I set out explicitly to refute the article, a quixotic enterprise but it doesn't cost anything. Nobody's going to refute Svensgard's hypothesis. Plenty of us can point out its inherent difficulties, though. Lack of any downward trend in cosmic rays, for instance, or the miniscule observed variation in cloud-cover during an entire solar cycle.
Then once again, it is well known that there is less cosmic rays when there is greater solar activity. And it is also well known that solar activity as such varies across the centuries. When solar activity is high, production of Carbon 14 is low. And temperatures are high presumably because fewer cosmic rays are getting through and hence fewer clouds are formed.
As presented in the article, a downward trend and signifcant cloud-response are givens. Which they aren't. Svensgard needs to be out there photographing cosmic-ray measuring stations to give some substance to his downward trend before he bothers the good folk at CERN.
There is no "trend". There is a variation depending on solar activity.

So it doesn't explain why there is a trend up in temperature, when there is no trend up in solar activity.

No, AUP, I have no magic way of finding proof or evidence. You're way ahead of me on being up on the literature. What I'm pointing out to you is that, at the moment, there is no evidence that one can find that confirms or debunks the AGW hypothesis. What you've found that is good enough for you is basically statements of known physics or phenomena which have been cobbled together to form a hypothesis. There is no evidence. Sorry.



Anything that would falsify either side of the debate.



As you should well realize by now, none of that is evidence. Papers published regarding warming observations cannot distinguish between AGW and GW. Absorbance data do not establish warming. Restating the hypothesis ad nauseam doesn't qualify either.

I'm 53 year old. Per the hypothesis, the warming has been occuring over my entire life and then some. Have I noticed anything? No. If the planet keeps warming at current rates, will I notice it? No. If the planet begins to cool, will that disprove AGW? No.

I am a scientist. I respect the work of other scientists who specialize differently. I'll let them do their work and judge it thereby. So, far, it's fairly interesting stuff.

Again, you are misinformed. Solar activity in fact varies across the centuries and not just in accordance with the 11 year solar cycle. And although cosmic rays have only been measured since 1935, it is possible to determine solar activity many centuries back in time. This is due to the variation in the amount of Carbon 14 produced as solar activity changes. And the variation of Carbon 14 can be measured via tree rings and by other methods. And once all the data is assembled, the direct correlation between solar activity and temperature is shown.

I am well aware of all that, but what about the trend over the last fifty years? That's the period during which the relevant warming has taken place, and direct measurements have been available. Forget the glorious past, what about the recent past? That's the period you're invoking Svensgard to explain, in preference to the more established view (AGW).

I wish I could find the Danish article I linked earlier in English as it is very informative.

Just pass along what you learned from it. Solar cycles, cosmic rays, and cloud-cover correlations we've already got. What else is in there?

I was referring to the article referenced here: "Mr Svensmark last week published the first experimental evidence from five years' research on the influence that cosmic rays have on cloud production in the Proceedings of the Royal Society Journal A: Mathematical, Physical and Engineering Sciences." Did you read this article?

I was explicitly referring to the Torygraph article, which is what you referenced before. And this quote adds nothing to that anyway.

I don't think they are crackpots. You seemed to be implying they were.

Perhaps you have an over-active imagination. Perhaps that's what you assumed I would say, and then read the implication into what I did say. Who can really know?

Glad to see we are in agreement that they are not crackpots.

Why suggest that they might be in the first place? You brought the word into the conversation, after all, in order to defend them. Like a pushy lawyer.

It's also hard to take this kind of "refutation" seriously.

It's almost impossible to take that sort of response seriously. Really, if that's all you've got to say, keep your gob shut. I say this as a well-wisher.

It is not a solar cycle of "Danish" cloud-cover, but of global cloud cover. And yes, the graph concerns +/- 2% of cloud cover. Which is pretty significant. Imagine if the global temperature changed 2% as a consequence! (Temperature in Kelvin, naturally).

OK, global, my Danish wasn't up to that. But it's certainly not +/- 2%. That would be - not imply, but be - a 4% interval, not the 2% interval that I referred to. It goes up to +1%, then it drops down to -1%,then it goes back to pretty much where it started. You then imagine that global temperature varies by some equivalent during that period, and that nobody's noticed it before. Hardly likely, is it?

You had nothing further to respond to. If you disagree, please tell me what it was.

How can I respond to "Again, you are misinformed"? I disagree with it, obviously, but I'm none the wiser as to why I shouldn't. And that was the entirety of the contribution I was responding to. So you're right, there was nothing further to respond to, and I responded anyway, with what I regard as sound advice. Ignore it if you will.

Sorry, I can't see what? I just said that I can't see you claiming the hypothesis is weak as you have shown no reason for me to think so. You still haven't.

In that case, I doubt I can. I doubt anybody can, for that matter.

Do let us know how the CERN thing works out.

I understand how this works, but you appear not to. Let me help you.

No hypothesis or theory is ever proven. In fact, hypothesis and theories can only be refuted. Those theories which explain as much or more than others, and cannot be refuted, are the winners. They are the ones you see in textbooks.

OK, so proven is the wrong word, but it doesn't mean that you can automatically assume that something is valid or even just the best answer until it is refuted.


Those would be great theories if only they explained anything or predicted anything. They don't.
I agree. That is the point.

This post is so out of touch with reality that it's hard to take seriously. Time to think Varwoche. Sheesh, and I thought it was a time to sow.

There are no trend lines, no R2 statistics. It is your side that beats the drum of "record" temps, so with 1998 being the "record" temp, it only stands to reason to view as the baseline for the current discussion. Cherry-picking this egregious is a sorry sight to behold.

It was Met O and others who predicted 2007 was the beginning of "record" temps exceeding 1998. I am simply showing it is going in the opposite sign. On the planet I inhabit, 12 of the 13 warmest years on record occurred in the past 13 years, 2007 amongst. link (http://www.cru.uea.ac.uk/cru/info/warming/)

You need to answer the following question: why is GISS diverged so far from HadCRU and others? I know you've already been told this but with hope springing eternal: it hasn't.

Why would using the cumulative sum be valid with highly autocorrelated data?

Why is the data autocorrelated, is it because there is noise added to a "typical" parameter and that this "typical" is moving?

A drunkard's walk might be autocorrelated, but this doesn't resemble that.

Anyway, as I said before, you don't need a cusum when you look at the simple mean-temperature vs time plot.

This resembles data for a parameter that is increasing.

Nothing about cosmic rays in there. I suppose you're using solar activity as a proxy. There is this though :

"He said firm conclusions about whether the present changes involve a long-term trend or a relatively brief aberration should come with continued monitoring into the next solar minimum, expected around 2006."

So how did that work out?

Hard to summarize a summary. Sorry. I suppose I could translate the entire article....

You said it was informative, so you surely carried away some salient points. But, whatever.

In other words, you didn't read it. OK.

Perhaps you thought they were top-notch and just failed to make your view clear.

I felt that "I don't know that I can refute a Torygraph article to your satisfaction, but I'll give it a shot" was unambiguous. You even thanked me, and then suggested that I "have a look at the article before criticizing". There's only one article involved at that point, so your confusion seems rather contrived.

See above.

Quite.

Then stop making throw-away comments which I can only answer in the way I did. Make substancial, constructive ones. Thanks.

I try, but "It's also hard to take this kind of 'refutation' seriously" doesn't give me much to work with. It's a bit throw-away, don't you think? If you simply say "You are mistaken" and move on, what's a man to do? Let it pass?

No, the scale goes from -2% to + 2%. Not sure which figure you were looking at?

The scale goes there, the graph doesn't. There's not much blue above 1% or below -1%. There's quite a lot of it closer to zero - but that's the way of it with cycles. Mostly there's just not much going on.

To see any trend requires examining multiple cycles, obviously. Any such trend will be considerably less than variation within a cycle. As an explanation for three decades of warming, the cloud-cover thing just doesn't hack it. Not without postulating cloud-cover as the dominant influence on climate.

You can respond by admitting that you were misinformed. Very simple.

I am not misinformed.

I shall do my best. Let me know when you become a skeptic.

Very barbed. Especially from someone who goes limp when "CERN" and "60 scientists" are paraded in front of him. I didn't notice you questioning exactly what involvement they had, you just appeared well impressed at their mere mention.

I think your initial intepretation was correct.

The CUSUM shows the temperature series to potentially a non-stationary series. Autocorrelation would be a potential source of this.

What this means is that the OP charts, plotting one against another, are highly susceptiable to finding spurious correlations (either statistical, or more commonly by simply looking at the two together). Which has been my point all along:

The plot in the OP is not very good statistical evidence for any inference that links the two series in any way.

OK, I am only arguing the case that this is evidence that the temperature is actually rising, and rising at an increasing rate.

This still leaves the question about the "A" in AGW...

However I am unable to outguess climate physicists on that.

Cyclical changes in the sun's energy output are not responsible for Earth's recent global warming ... Instead the findings put the blame for climate change squarely on human-created carbon dioxide (CO2) and other greenhouse gases—reinforcing the beliefs of most climate scientists. link (http://news.nationalgeographic.com/news/2007/07/070712-sun-climate.html) no indication of a systematic trend in the level of solar activity that can explain the most recent global warming link (http://www.agu.org/pubs/crossref/2005/2005GL023621.shtml) Sunspots alter the amount of energy Earth gets from the sun, but not enough to impact global climate change ... The difference in brightness between the high point of a sunspot cycle and its low point is less than 0.1 percent of the sun's total output ... If you run that back in time to the 17th century using sunspot records, you'll find that this amplitude variance is negligible for climate. link (http://news.nationalgeographic.com/news/2006/09/060913-sunspots.html)

Yes I am. I think I explained about how the connection between solar activity and cosmic rays is well known.

It is. It's noisy, but across a few cycles it's pretty clear.

No idea, sorry.

A more recent meta-study concludes that there's been no trend in solar activity or cosmic rays over the last fifty years.

It is indeed very informative and I wish I could find it for you in English. No luck so far, though.

Don't worry about it. I find something informative when I go away with at least one "Well, I didn't know that" in my head.

OK, I suppose that my question regarding whether you read the "article" could be interpreted as the news article I linked to itself and not the article referred to in the article. In any case, did you read the article referred in the article?

The article of the which part? As I recall the link was to the Torygraph article. Easy meat.

I was referring to your "argument" at the point in question.
You must be looking at a different graph than I am. The blue curve alone varies between at least 1.6% and -1.8% as far as I can see.

At the extremes. 3.4%, but notice how little of the blue is out there, and how much closer to the zero-line. And, of course, most of it cancels out, so at the end of the cycle there's not much difference at all.

So the effect is there, but you've gone nowhere in demonstrating that there's a trend across solar cycles. That will necessarily be far less than the variation within a cycle.

Not only do the 3 recent decades of data fit very well, but so does data going back to before the year 1000, including the "little iceage" and the Maunder Minimum. It may be an incredible coincidence, but denying the data by claiming it simply isn't there, is pretty close to woo.

I'm certain there's no reliable cloud-cover data going back to Knut's day.

I have shown that you are. There is in fact an increasing solar activity and has been for decades. And there is a corresponding decrease in cosmic rays, also across the decades. You claimed this wasn't the case. Ergo, you were misinformed.

There is no increase in solar activity over the last fifty years.

Yes, that was barbed. But I think we both are quite adept at barbs. :)

That was irony. You really did go tickle-my-tummie to "CERN" and "60 scientists", so as a wannabe sceptic you don't rate yet.

Perhaps, but dismissing alternative explanations out of hand certainly doesn't seem very skeptic/sceptic.

I haven't used up all this bandwidth by being out-of-hand. I've provided good reason for my consigning this alternative to the darkest recesses of unlikelihood.

The problem with the Solar Constant (which is not a constant) is that until very recently there has not been a great way to measure it that excludes effects of the atmosphere. And early measurements, even those during the space age suffer from having been done in all sorts of ways that are hard to mutually calibrate.

So, it is really hard to find ANY trend in the solar output that you can be really confident of, but you can set some limits, and those limits cluster around a zero change, but do not exclude a small change up or down.

Can you show me some figures for that? Which best represents solar activity: insolation, for which we have only recent direct measurements, sunspot frequency, or something else? I looked at sunspot counts recently and they don't show a recent (late 20th century) increase.

I used these figures (http://solarscience.msfc.nasa.gov/greenwch/spot_num.txt). They are easily put in a spreadsheet to produce graphs.

The Sun is one of my interests. And I can confirm that other than the usual cycles there does appear to be no trend in the last 60 years or so. If there is, I've not seen the paper proving it. And knowing the Sun has become vital to certain commercial interests and so it has been an object of intense scrutiny for about that period of time.

The link is to the third group of discussion hosted by Svelgaard, a noted solar exert, on Climateaudit. The post count is upwards of 1500, and Svelgaard tries to answer every question asked.

A brief summary of his attitude is that total solar variability is likely low, which means that climate sensitivity to solar may be high (obviously it is at least 2x the sensitivity to greenhosue gas forcing). But for various reasons, sensitivity to solar might be considerably higher.

There are satellites up there looking at nothing else. All day, every day.

What we get from the other end is argumentum ad proxy. Sunspots are their brittlecone pines. I bet, though, that as things warm up over the next two-to-seven years the positive phase of the Solar Cycle will be trotted out in explanation. By at least one of the usual suspects, and by at least two newcomers.

If I'm wrong, I'll eat brittle cone and admit it. If I'm right - well, that's reward enough in itself. I may make mention of it from time to time, of course ...

The link is to the third group of discussion hosted by Svelgaard, a noted solar exert, on Climateaudit. The post count is upwards of 1500, and Svelgaard tries to answer every question asked.

Doesn't he have work to do?

A brief summary of his attitude is that total solar variability is likely low ...

Well, yeah, we can see that. Satellites, yadda-yadda.

... which means that climate sensitivity to solar may be high ...

"Means" given what assumptions? The ones that come with the "may"?

... (obviously it is at least 2x the sensitivity to greenhosue gas forcing).

You perhaps mean that for the hypothesis to stand it would obviously have to be at least twice the sensitivity of greenhouse forcing. Does he given any reason why climate should be so selective in its responses? Down here it's all about fluids and energy accounting. It strikes me that rather more is being loaded on clouds than they can support.

But for various reasons, sensitivity to solar might be considerably higher.

Various reasons, and they "might". What are these reasons again? I think we've strayed into mystic physics territory.

I'm not sure (haven't looked into it) to what extent the interaction between cosmic rays and the solar wind etc are discussed in these threads. They should be. Svelgaard comes across as conservative, but open minded.

He comes across as someone reveling in the attention he's getting. I don't see him dropping his hypothesis any time soon.

But that does not do the subject justice, so let me again suggest reading the thread.

How does he answer the argument that global warming is an artefact of bad measurement practices? UHI and all that stuff? This guy's trying to explain why problematic warming is being caused by the Sun. What do you like, a random Dane's argument or McIntyre's? I reckon McIntyre will outlast the Dane.

That doesn't work, of course, so the solar thing du jour is about the length of the cycles, which is supposed to reveal some aspect of mystic physics. It takes data-mining to desperately dangerous depths.

There are those who have made predictions based on what that data-mining has "revealed". Enough of them that at least some can claim to have called it, given the variety. Not many will be able to claim three in a row. Before that the subject was a backwater with a somewhat nutty reputation. From the moment solar cycles were identified people went looking for a climate signal and an odd sub-culture emerged, one side finding signals, the other knocking them down.

It never entirely went away, and suddenly it's thrust into the limelight because climate is centre-stage, and anything related is fair game.

I will point out a similar quandary over whether cigarette smoking caused cancer.

Lung cancer happens at times in individuals who never smoked. So, for many years the defense of the Tobacco Industry was that you could not look at ANY specific death as a result of lung cancer and say definitively that it was caused by smoking. And then they would draw the conclusion that therefore no harm had ever been proven because you could not point to a single provable case.

Reality has a noisy signal, and when we try to find a trend we must make a rational assessment of probabilities.

One really does wonder about this type of thinking. Something is okay to discuss, even though a quick check shows all the issues and faults, and the published rebuttals. So sad. And Lockwood/Frolich were the ones that were going to "drive the last nail into the coffin of the sun". Is there a paucity of quality peer reviewed literature asserting "solar has no current influence on climate"?

Another pretty picture, but it does claim to represent the "accurate long-term trend" from 1860 to 2000. Which you'll notice is upward. You'll also have noticed that 140 years is about two 60-80 year cycles, and the trend has gone up across both of them. The cycle is visible, but there's clearly some other influence imposed on it.

The accurate trend-line is alarming enough in its implications, and is the one that's taken account of. The really silly line in that picture is the thick black one, the current "no warming" period. It's a projection from a few years ago, and it's still not quite flat.

What Capeldodger does not tell you is that these charts have been discussed on this forum before including various references and supporting studies. As for requesting a reference to Rodale's graph, sheesh. That's just the old CO2 trend and two major temperature series. Which everyone should already accept. So this is a chart of basic raw data, rather than a chart which forms a correlation or a conclusion from that data. The chart I presented does form a conclusion, by noting a high correlation of the sinusoidal curve with the raw temperature data. The source is given below -

I took this graph and marked it up to indicate some of the alleged trends and what I thought were more realistic. The issues that it shows are not that "there is or is not global warming" but...
Charts are often made starting in 1900 and ending in the current, these exaggerate warming by starting at a low and ending at a high. (Red line wrong, blue line right).
Charts for recent decades often have shown a linear continuation of warming which is not happening. (Purple line wrong, current climate is following the black line)
Tsonis 2007 and several other scientists, including the arthors of the study from which the 60-80 year chart was made, indicate that temperatures should go down in the next decades, not up.
Hansen, Gore and other climate alarmists started agitating largely in 1988 and have been riding a known, predictable upward trend of temperature due to natural causes while promoting it as due to man's CO2 emissions. That upward trend is now over and the temperatures are stable and or declining.
The chart acknowledges a trend toward a increase in temperature over the last century.Does that answer your question?

I draw your attention to two sets of summary graphs and note that R = 0.80 to 0.90 for all series studied by these scientists.


First graphs and discussions.

Figure 5.3 The full spectrum of unsmoothed reconstructed temperatures from ice core samples for the last 1420 years. (http://www.fao.org/docrep/005/y2787e/y2787e1v.gif)
Spectral analysis of the time series of dT, ACI and LOD are presented in Fig 5.4. It is clear that the spectra of dT, ACI and LOD are rather similar. Primary maxima of dT and ACI are 50-55 years, and the period of the LOD cycle is 64 years. Other maxima are less pronounced, although there are clear peaks of ACI and LOD values (19 and 23 years, respectively) in the high frequency (left) range of the spectrum. The latter indicates that there is a global climate cycle with a frequency of about 20 years. Its effect on biota should be taken into account.

Second graphs and discussion.

You won't be proved wrong because you've never taken a definite position. I could be proven wrong, as could varwoche, because we've taken definite positions, based on sound judgement.

You love calling me names, don't you CD.

AUP made a specific point that solar influences have not contributed to the recently recorded phenomenon. Again, for completeness, this is what he said...

Of course the sun is the major influence on the climate, but it's not a driver of change at present.

... which is a bit like trying to have your cake and eat it too. And, worse, it's unsubstantiated.

Rubbish. Your ignorance of what it's founded on is your problem, not something to be projected onto others. Educate yourself, don't demand that we go over the same ground yet again

You have clearly failed to educate yourself in a subject on which you are pontificating. You do come across as a pompous ass, there, I've said it..

This really is rich coming from you, CD. I've found your understanding of thermodynamics comical. I'm also waiting for your explanation as to why, if all the physiscs you rely on for your belief that AGW has been established ss fact, scientists trying to deliever a falsifiable hypothesis have failed to do so over one hundred years (your figure, not mine).

You'll have to wait a while to prove us wrong. Let us know how that works out for you.

Here's another of your favorite slights. As I've pointed out to AUP previously, the AGW side hasn't put out anything falsifiable either so there's no proving your side wrong. You keep harping on the net warming occuring on the planet as if that were proof of your hypothesis but it isn't. I think you need to study up on thermo before you try to make that k's (pun intended but you probably won't get it).

Warmers have argued that solar cannot account for global temperature rise since 1950, and your graph does show flat from then forward. Warmers look for solar to produce an immediate and dramatic effect, not any effect delayed by years or decades.

For CO2 they have all kinds of nuanced delayed effects, and can blame or attribute most anything on CO2.

For the last decade and the current solar minima, It is hard to not attribute some part of the current level temperatures to solar. How much is open to question.

However, the graph may possibly support the hypothesis that CO2 increases follow warming, not the other way around. And, if the oceans are indeed acting as one large "solar capacitor", this may account (in part) for the observations at Mauna Loa that higher fractions of CO2 are being recorded at that station.

Better still, wouldn't it be nice if someone would answer as to why the lower troposphere isn't warming as "the" climate models dictate? How can it ever cool if CO2 has such powerful heat retaining abilities?

1) the models are always wrong but they keep correcting them every couple of years to fit what really happens.

The total heat in the troposphere shows the actual amount of the greenhouse effect. If it isn't that much heat, it ain't that big a greenhouse effect. That's what we have, it seems.

No way to argue from authority - the authority is the actual middle troposphere temperature, not some UN agency.

Since this agrees with Schwartz's concepts on ocean heat capacity, where do we go from here? Looks like the case is getting pretty solid. Multiple lines of evidence with mutual, interlocking conclusions that agree nicely.

zeusbheld
25th February 2008, 03:28 AM
What Capeldodger does not tell you is that these charts have been discussed on this forum before including various references and supporting studies.

i asked *you*. don't pass the buck. you are the one making a claim. i'm new here, and wondering why you and Rodale consistently fail to contextualize the graphs you provide. if, EVERY time you post a graph, you can provide a link to its original context, i'm sure i'm not the only one who would be grateful. seems like common sense to me. apparently not.

Also, if you both can provide links to these threads you reference i'd be grateful.

at present i'm neither AGW skeptic nor believer, more like AGW agnostic. i expect to stay that way for some time as the math for modeling climate is.... complicated.

*your* tactics look dodgy, but perhaps you are just sincerely assuming a greater familiarity with the material in question? nonetheless it sure looks like a lack of full disclosure.

what i have noticed the considerable shortage of AGW skeptic papers in relevant peer review journals. so in short, i'm inclined to believe, based on skimming peer-reviewed journals, that a majority of relevant scientists are inclined toward AGW, but that doesn't prove it's happening, does it. as far as i can it certainly hasn't been proven yet, but it certainly hasn't been disproven either.

in short, my position is, "i don't know." if i were a policymaker i'd feel more inclined to investigate until i have a position. but i'm not. as an individual, i expect my 'carbon footprint' is less than most who are adamant about AGW--but for reasons having nothing to do with AGW (i don't own a car as i live in a city and dont' need or want one, among other things).

As for requesting a reference to Rodale's graph, sheesh. That's just the old CO2 trend and two major temperature series. Which everyone should already accept.

ALL charts and graphs should be referenced, as it is incredibly easy to doctor data when plotting it to support any claim made. i know next to nothing about the science involved, but i DO know how to massage data when plotting it. i worked in the graphics department of an investment bank for a while; my JOB was to show whatever trend was desired by the banker.

all the graphs you guys are posting look specious, at best. that may be only because plotted trends without supporting justification set off my alarm bells.

So this is a chart of basic raw data, rather than a chart which forms a correlation or a conclusion from that data.

the first graph you present is most definitely NOT 'basic raw data' there is a trend curve clearly marked on it. was that a deliberate attempt to con me, or don't you know what "basic raw data" is?

where is it from? it says AFTER Kyatshorin and Lyubushin, does this mean if i find the paper by these people (the one you still refuse to link to; i did NOT see it in the K + L paper you linked to) i'll get the contextual info for this graph, or did you take the graph from some OTHER article which relies on K +L?

The chart I presented does form a conclusion, by noting a high correlation of the sinusoidal curve with the raw temperature data. The source is given below -

again, the source is NOT given bellow, and b) after they rather efficiently (i didnt do the math, but it looked purty good) establish the correlation of the sinusoidal curve with raw temperature data they say

The concept of generating forecasts of anthropogenic climate change and consequent changes in fish production is beyond the scope of this study.

call me naive, but i tend to interpret 'beyond the scope' as 'no comment.' Is that why you never show things in their original context? if you're trying to convince me that your'e trying to con me, you're doing a GREAT job.

I took this graph and marked it up to indicate some of the alleged trends and what I thought were more realistic. The issues that it shows are not that "there is or is not global warming" but...
Charts are often made starting in 1900 and ending in the current, these exaggerate warming by starting at a low and ending at a high. (Red line wrong, blue line right).
Charts for recent decades often have shown a linear continuation of warming which is not happening. (Purple line wrong, current climate is following the black line)
Tsonis 2007 and several other scientists, including the arthors of the study from which the 60-80 year chart was made, indicate that temperatures should go down in the next decades, not up.
Hansen, Gore and other climate alarmists started agitating largely in 1988 and have been riding a known, predictable upward trend of temperature due to natural causes while promoting it as due to man's CO2 emissions. That upward trend is now over and the temperatures are stable and or declining.
The chart acknowledges a trend toward a increase in temperature over the last century.Does that answer your question?
no; for one thing, the paper *you* link to (no i didn't go through it and to the math) claims the climate oscillates, but explicitly makes no claims regarding an overall long-term trend.
Secondly, you make a lot of trend claims with NO links to supporting evidence and did you at least skim through the K+L paper and notice all that math supporting their claims? apparently not, as you've taken the liberty of drawing trendlines with a crayola (or the photoshop version thereof).

Again, from the paper *you* linked to (http://www.fao.org/docrep/005/y2787e/y2787e01.htm#TopOfPage), in case you missed it the first time:

The concept of generating forecasts of anthropogenic climate change and consequent changes in fish production is beyond the scope of this study.

yet you dare to tread where the authors don't, without the need for dozens of pages of tedious math, apparently? you lost me there.

I draw your attention to two sets of summary graphs and note that R = 0.80 to 0.90 for all series studied by these scientists.
and this is enough for *you* to draw a conclusion the authors of the paper don't? wow i'm impressed.

Don't Blame Sun for Global Warming (http://news.nationalgeographic.com/news/2006/09/060913-sunspots.html)

No indication of a systematic trend in the level of solar activity that can explain the most recent global warming (http://www.agu.org/pubs/crossref/2005/2005GL023621.shtml) This is the evidence that Dr. Imago requested and as yet has ignored.

I'd ignore it too, if I posted delusional nonsense such as...
It's quite clear to everyone who's paying attention that they've hung their hat on carbon dioxide. What is not clear - or proven - is that this is the correct place to do so.

Seemingly the material issue in your discussion is 60-80 year cycles, here are a few random looks at this reality. This 60-80 year cycle isn't really in dispute, what is I think might generally be described is whether the influence of man's emissions and so forth overwhelm this and other natural cycles, including solar and others. These are just a few, this is a big subject and please note that it is only one of several dozen that are relevant to the so called "climatology' field.

I would second that. The problem of establishing whether or not AGW is occuring is more complex than it seems. Two or more different warming drivers (natural vs anthropogenic) need to be resolved from one another. At present, the pro-AGW side can only point to the construct of their hypothesis. The anti-AGW side can only rebut with pointing out AGW predictions that have not come to fruition.

You may want to compare this debate vs the Malthusian scares that arise from time to time. I'm not saying that AGW is a scare although some politicians are certainly using it for that purpose. However, history speaks volumes here. Don't give away all your belongings just yet.

I would tend to agree from the weight of the evidence. The scientific foundation of the AGW hypothesis appears sound but way overhyped. The people who tend to believe it at its worst don't seem to be too well grounded in scientific theory.

I've seen too many greenie carnival shows to trust that bunch at anything. A fair amount of my work is to debunk bad modeling by searching out and demonstrating actual measured field data. Field data ALWAYS trumps modeling, no matter how much we agree with the model's construction. Constantly updating your predictions on the basis of reality is called research, not verification. Add to that the fact that many complex models can only be debunked in fact and not by logic, and this AGW thing seems less and less ominous every passing year. (That's why I bring up the Malthusian scares as they were falsified by history, not theory.)

Is it that there is or is not a 60-80 year climate cycle that is influential in climate?

correct me if i'm wrong but that was the subject of the paper you linked to? they went through an awful lot of (what looked like) pretty good math (i was too lazy to work through it) to get that sinusoidal trendline.

Is it that there is or is not "global warming?"

well i've seen enough evidence that there is some global warming lately, not enough to convince me as to whether (or not) it is a) a long term trend or b) anthropogenic.

however, if you've got evidence that it is (or is not) warming i'd be interested in that, but i only look at science papers the rest is just 'net fun and games.

no. the issue is not the 60 - 80 year cycle, the issue is that you cited a paper which clearly establishes said cycle, but you *seem* to be insinuating that it is evidence against anthropogenic global warming. the authors themselves say, in their conclusion:

The concept of generating forecasts of anthropogenic climate change and consequent changes in fish production is beyond the scope of this study.

what i saw in *your* post is you drew heavily from their study, didnt' link to it until pressed, and concluded by drawing trend lines on the graph in photoshop.

what i want from you,

a) is science papers that explicitly support your conclusion.

failing that, if you're amibtious,

Human Impacts on Climate

Adopted by Council December 2003
Revised and Reaffirmed December 2007

The Earth's climate is now clearly out of balance and is warming. Many components of the climate system—including the temperatures of the atmosphere, land and ocean, the extent of sea ice and mountain glaciers, the sea level, the distribution of precipitation, and the length of seasons—are now changing at rates and in patterns that are not natural and are best explained by the increased atmospheric abundances of greenhouse gases and aerosols generated by human activity during the 20th century. Global average surface temperatures increased on average by about 0.6°C over the period 1956–2006. As of 2006, eleven of the previous twelve years were warmer than any others since 1850. The observed rapid retreat of Arctic sea ice is expected to continue and lead to the disappearance of summertime ice within this century. Evidence from most oceans and all continents except Antarctica shows warming attributable to human activities. Recent changes in many physical and biological systems are linked with this regional climate change. A sustained research effort, involving many AGU members and summarized in the 2007 assessments of the Intergovernmental Panel on Climate Change, continues to improve our scientific understanding of the climate.

During recent millennia of relatively stable climate, civilization became established and populations have grown rapidly. In the next 50 years, even the lower limit of impending climate change—an additional global mean warming of 1°C above the last decade—is far beyond the range of climate variability experienced during the past thousand years and poses global problems in planning for and adapting to it. Warming greater than 2°C above 19th century levels is projected to be disruptive, reducing global agricultural productivity, causing widespread loss of biodiversity, and—if sustained over centuries—melting much of the Greenland ice sheet with ensuing rise in sea level of several meters. If this 2°C warming is to be avoided, then our net annual emissions of CO2 must be reduced by more than 50 percent within this century. With such projections, there are many sources of scientific uncertainty, but none are known that could make the impact of climate change inconsequential. Given the uncertainty in climate projections, there can be surprises that may cause more dramatic disruptions than anticipated from the most probable model projections.

With climate change, as with ozone depletion, the human footprint on Earth is apparent. The cause of disruptive climate change, unlike ozone depletion, is tied to energy use and runs through modern society. Solutions will necessarily involve all aspects of society. Mitigation strategies and adaptation responses will call for collaborations across science, technology, industry, and government. Members of the AGU, as part of the scientific community, collectively have special responsibilities: to pursue research needed to understand it; to educate the public on the causes, risks, and hazards; and to communicate clearly and objectively with those who can implement policies to shape future climate.

given AGU's position, i'd really like to see the full content of that paper (without having to pay nine bucks).

study based on applied theory of chaos (cycle....)
http://www.worldclimatereport.com/index.php/2007/08/17/climate-change-chaos/

that looks interesting, but it's a blog. got the original paper by Tsonis, Swanson, and Krakov?

other notes. "chart was after" means it is from these Russians. I picked a html version of the PDF, the PDF is quite large, something like a hundred pages. The html version may be later in date.

is this the paper on the 60-80 year cycle by Klyatshorin et al? or another paper? i've got the Klyatshorin paper now, thanks.

"raw data " referred as I recall to David Rodale's graph, which is just three lines of raw data. Sinusoidal chart does of course have the sinusoidal curve fit superimposed on the raw data. 2nd sinusoidal chart which you note looks like it is marked up with markers, those were done by me purposely to illustrate certain points.

those certain points are what i want you to establish transparently, otherwise i have to assume that it is *your* conclusion based on conjecture.

I would second that. The problem of establishing whether or not AGW is occuring is more complex than it seems. Two or more different warming drivers (natural vs anthropogenic) need to be resolved from one another. At present, the pro-AGW side can only point to the construct of their hypothesis. The anti-AGW side can only rebut with pointing out AGW predictions that have not come to fruition.

You may want to compare this debate vs the Malthusian scares that arise from time to time. I'm not saying that AGW is a scare although some politicians are certainly using it for that purpose. However, history speaks volumes here. Don't give away all your belongings just yet.

do link to these "Malthusian scares" if you can.

what i find interesting about these AGW threads is that we have a thread full of (apparent) non-scientists and so many have a strong opinion on something very complex.

so far the anti-AGW people have been rather sloppy IMO. but again, i'd rather base *my* opinion on science papers than on keyboard warriors. that said, the better keyboard warriors can often cough up links to science papers to support their convictions. i find these papers interesting, if difficult, reading.

I would tend to agree from the weight of the evidence. The scientific foundation of the AGW hypothesis appears sound but way overhyped. The people who tend to believe it at its worst don't seem to be too well grounded in scientific theory.

well, at its worst you have "The Day After Tomorrow." but Hollywood is a bit of a straw man innit.

I've seen too many greenie carnival shows to trust that bunch at anything. A fair amount of my work is to debunk bad modeling by searching out and demonstrating actual measured field data. Field data ALWAYS trumps modeling, no matter how much we agree with the model's construction. Constantly updating your predictions on the basis of reality is called research, not verification.

is this what you do for a living? are you a climate scientist? if not, what got you into this strange hobby?

Add to that the fact that many complex models can only be debunked in fact and not by logic, and this AGW thing seems less and less ominous every passing year. (That's why I bring up the Malthusian scares as they were falsified by history, not theory.)

in principle i'd agree that transparency around data collection and data collection methodology is vital. science advances through failing to disprove things in spite of intense effort, not through proving things.

it's worth noting that "AGU" host many papers which tacitly assume AGW, like this one. (http://www.agu.org/journals/scripts/highlight.php?pid=2007GL032179)

Looks like a good study. Not what I object to which is "Alarmism".

Discussion, Motl. (http://motls.blogspot.com/search?q=tsonis)

They argue that the synchronization disappears once the coupling between all/most of these cycles gets too high: a major climate shift is a consequence. The amount of synchronization decides about the ENSO variability as well as the global temperature, as they demonstrate by an analysis of major indices in the 20th century. This climate shift may be seen as a bifurcation - branching of one possible solution into two. It is accompanied by changes of the coupling parameter which acts as an external parameter.

....the shifts have occurred or will occur around 1913, 1942, 1978, 2033, 2072.....a 0.2 Celsius cooling between 2005 and 2020 should be followed by a 0.3 Celsius warming until 2045 or so and by cooling in the rest of the 21st century. 2100 is seen as more than 0.1 Celsius cooler than 2005.

I don't do links--LIIINNNKKKKSSSSS!!!--esp. to issue of common knowledge, so here are some references, and if you are not as blinkered a far lefty as you otherwise seem to be, look them up.

Early 1960s: Silent Spring: hunters, pollution and habitat diestruction were killing off all the wildlife; all wildlife would be gone by 2000.
Outcome: LOL!

Mid-late 60s: The population bomb: we were going to have a SRO world by sometime in the 1990s resulting in global famines, etc.
Outcome: LOL!

1960s and 70s: by 2000 our world would be uninhabitable due to pollution.
Outcome: LOL!

Early 70s: we would be OUT of oil (completely out) by the early to mid-90s.
Outcome: LOL!

Mid to late 70s: The coming Ice Age. Global climate was growing dangerously...colder, and we were entering a new ice age.
Outcome: LOL!

70s-80s: Using up all arable land (by about 2000). We were putting too much land under the plow which would cause regional and global famine as soil "failed" due to poor farming practices.
Outcome: LOL! (100s of thousands of acres in the US and Canada have been voluntarily taken out of production and allowed to revert to natural state, producing, accidentally, the Popov's "Buffalo Commons"--this headlong race to return most of the central part of N. America to its natural state has paused recently because...more land is needed for production of corn to make...ethanol).

In fact that was a minority view (http://www.usatoday.com/weather/climate/globalwarming/2008-02-20-global-cooling_N.htm).

Thomas Peterson of the National Climatic Data Center surveyed dozens of peer-reviewed scientific articles from 1965 to 1979 and found that only seven supported global cooling, while 44 predicted warming. Peterson says 20 others were neutral in their assessments of climate trends.

The study reports, "There was no scientific consensus in the 1970s that the Earth was headed into an imminent ice age.

"A review of the literature suggests that, to the contrary, greenhouse warming even then dominated scientists' thinking about the most important forces shaping Earth's climate on human time scales."

Although it may or may not have been a minority view, global cooling certainly fits the "Malthusian scare" concept. There should normally be a reality that "extreme scare scenario" represents a minority view anywhere you go, right?

Just like we can go and look at decadal trends in publishing of stock market books and always find "The Coming Crash....<insert hyperbole as desire>", but reality is pretty mundane.

Wiki article (http://en.wikipedia.org/wiki/Malthusian_catastrophe). Pretty even-handed. Wiki article (http://en.wikipedia.org/wiki/Club_of_Rome)on the Club of Rome, the last group I know of that tried to make a living off Malthusian scare theory. Do a search on them. A popular book from the 70s called The Population Bomb (http://en.wikipedia.org/wiki/The_Population_Bomb) had people believing in food riots in American cities. I think you'll see some parallels. Note especially that Malthusian theories have never been theoretically disproven although they have been falsified by fact.

what i find interesting about these AGW threads is that we have a thread full of (apparent) non-scientists and so many have a strong opinion on something very complex.

I believe you're seeing backlash of strict science vs trendy science. AGW has no falsifiable statement and the anti-AGW side cannot refute other than point out predictions that are not or have not come true.

so far the anti-AGW people have been rather sloppy IMO. but again, i'd rather base *my* opinion on science papers than on keyboard warriors. that said, the better keyboard warriors can often cough up links to science papers to support their convictions. i find these papers interesting, if difficult, reading.

To be very frank, you're in the wrong place if you want a highly technical discussion. This is a skeptic's forum and as such what you'll find in response to most claims is "show me". You will sometimes find someone in the crowd with a direct and succinct refutation of a claim but the claim here is AGW which, as I've pointed out, is pretty much based on faith at this point.

I also believe you are being a bit critical of the anti- side while letting the pro- side ride with provenly false claims such as "the science is settled", "AGW is a theory", "AGW is proven", "you can't disprove AGW without falsifying modern thermodynamics", "a warming planet proves AGW", and so on. All these statements are bunk but they surface over and over again. Other than that, I like your skeptical and open-minded approach.

I'm an analytical chemist who at this moment is involved in quite a bit of ecological, environmental and safety modeling. I see disturbing parallels to really bad modeling practice in some of the pro-AGW arguments. Generally, though, I don't like to see science so abused.

in principle i'd agree that transparency around data collection and data collection methodology is vital. science advances through failing to disprove things in spite of intense effort, not through proving things.

Well, it advances both ways. The most important step in discovery is to differentiate competing hypotheses by devising a definitive test. That is, a test that, given an outcome, would exclude at least one of the hypotheses from being true. We have nothing like that yet for AGW yet the proponents won't stop claiming that the science is established. KInda irks me.

You love calling me names, don't you CD.

I don't remember thinking of one. What was it?

AUP made a specific point that solar influences have not contributed to the recently recorded phenomenon. Again, for completeness, this is what he said...



... which is a bit like trying to have your cake and eat it too. And, worse, it's unsubstantiated.

No, it's not like that at all.

Want a source? Here ya go:

Solar influence level since 1960. I knew that.

If this construct is accurate, you can't conclude what AUP has. Period.

I find it hard to conclude otherwise. How do you do it? There's no solar trend since 1960. There are wiggles in the line, but have you looked at the scale on the y-axis? Perhaps more to the point, have you ever read How To Lie With Statistics? It's a must-read, IMO.

All name-calling aside.

What was that name? I must have thought it good at the time.

Or, do you want to now call NOAA a bunch of liars/deniers/asses?

Note especially that Malthusian theories have never been theoretically disproven although they have been falsified by fact.

that's all pop stuff though. speaking for myself, i'm not interested in pop stuff because that sort of thing would happen anyway, as it presses our instinctual buttons. it has no bearing whatsoever on whether the claims have anything to do with reality.

got more recent stuff? and are there science papers backing these people up? granted i wasn't there but i don't get the impression that these ideas were widely accepted and researched by scientists; looks more like a few outliers cashing in on our instinctual desire to thrill at being scared.

I believe you're seeing backlash of strict science vs trendy science. AGW has no falsifiable statement and the anti-AGW side cannot refute other than point out predictions that are not or have not come true.

the appearance of the AGW scientific debate to a layperson--as opposed to net fora, where the appearance is shrill loons coming out of the woodwork--is that it will come down to these models consistently making accurate predictions. that still may not be enough for strict scientific fact, but my impression is it would add considerable weight to the hypotheses involved. my impression, also, is that given that climate is measured in 30 year chunks, it will take a while for predictions yea or nay to reach a critical mass.

if strict science vs trendy science is really happening, string theory may be headed for a world of hurt, huh?

To be very frank, you're in the wrong place if you want a highly technical discussion. This is a skeptic's forum and as such what you'll find in response to most claims is "show me".

which is why i'm here. "show me." i'm not necessarily looking for a highly technical discussion, but i do need one rooted in science, and i'm hoping for more pointers to toward actual research papers. seems to me that any skeptic worth their salt would want to see the [scientific] case in matters of science, and at least try to understand what's being said.

You will sometimes find someone in the crowd with a direct and succinct refutation of a claim but the claim here is AGW which, as I've pointed out, is pretty much based on faith at this point.

well here's the thing. i don't see where the AGW crowd have proved their point, but there DO seem to be more people publishing papers on it than publishing papers with alternate explanations, and papers tacitly accepting it. that doesn't mean it's 'scientific fact' of course.

I also believe you are being a bit critical of the anti- side while letting the pro- side ride with provenly false claims such as "the science is settled", "AGW is a theory", "AGW is proven", "you can't disprove AGW without falsifying modern thermodynamics", "a warming planet proves AGW", and so on. All these statements are bunk but they surface over and over again.

i've been critical of the other side, too--someone made the absurdly irrelevant claim that anti-AGW types need to "get out more" as if going outside and seeing your petunias bloom earlier every year would settle anything (disclaimer: i obviously know nothing about gardening).

i haven't seen too many of the kinds of statements you describe, mainly perhaps because of my timing in entering this board and because the shrill irrelevance of posters like "Tokie" drowns them out. i picked on MHaze not primarily because of the obvious sloppiness of his citations but because i expect somewhere in there are the resources to make a better case, and i'd like to see it. notice i haven't picked on this "Rodale" fellow as much because he seems rather lost in his own world and unlikely to provide the kind of transparency i'm looking for.

most of the statements you describe are obvious howlers, only ones that aren't are "AGW is a theory" and "the science is settled" (which are essentially the same claim, are they not?). and *my* forays into science papers have uncovered no stronger claim than a consensus amongst relevant scientists. the consensus seems demonstrable but that IN NO WAY to me implies the science is "settled."

most of the shrilly irrevant posters on both sides are howling like mad dogs because AGW IS what one generally refers to as "post-normal-science"---policy decisions attempted before the science is settled. by its nature it will attract more partisan loons on both sides than anything else. and most likely frustrate people who can understand the science involved so much as to drive them off (my vulcanologist friend, who spends the bulk of his time studying aircraft contrails rather than is/is there not AGW, doesn't bother with this sort of net bickering).

Other than that, I like your skeptical and open-minded approach.

i suppose my "science" position at present can be summed up as follows:
it is apparent to me that the science isn't settled. it appears, from the papers i've skimmed, that there IS an anomalous climate shift, that hasn't been easily explained away by the usual influences on climate. "global warming," in other words, appears to me to be happening, although "climate change" is a more apt term. the permanence, cause and degree of this change are not settled as far as i can tell. AGW seems to my untrained eye plausible enough but NOT in any way "proven."

anyone, feel free to jump in and correct any of that, but anyone who wants to be at all persuasive, please offer links to science papers and transparent sources.

my "policy" position would be summed up:
it may be possible that as the pro-AGW crowd assert, that the problem is something we should start fixing before it is settled, but i'm frankly not sold on that yet at all. that said i'm inherently for alternative fuels as dependence on 'foreign oil' is a bad thing, i'm tentatively for nuclear power, "sustainable" architecture, fuel efficient transportation and clean rather than dirty coal technology regardless of AGW.

having clearly stated my position, i now expect both pro- and anti-AGW types to jump down my throat.

Cal Tech et al (http://www.sciencedaily.com/releases/2007/10/071016090525.htm), Oct 2007
A team of American and Canadian scientists has devised a new way to study Earth's past climate by analyzing the chemical composition of ancient marine fossils. The first published tests with the method further support the view that atmospheric CO2 has contributed to dramatic climate variations in the past, and strengthen projections that human CO2 emissions could cause global warming.

Rutherford Appleton et al (http://news.nationalgeographic.com/news/2007/07/070712-sun-climate.html), July 2007
Cyclical changes in the sun's energy output are not responsible for Earth's recent global warming ... Instead the findings put the blame for climate change squarely on human-created carbon dioxide (CO2) and other greenhouse gases—reinforcing the beliefs of most climate scientists.

Human activities, chiefly the burning of fossil fuels, have upset a natural balance in ocean acidity ... We have very clear evidence, and there is no doubt this is occurring ... Ice core measurements show that oceans have not been as acidic as they now are for at least 650,000 years, and probably millions of years beyond

Here are some studies you might consider:

there are some credible institutions listed there (in particular, i have an inordinate fondness for Scripps, since i saw my first-ever real live shark there when i was five)...

and some very interesting hypotheses...

BUT here's the thing. they are articles and press releases. NONE are science papers. some are articles ABOUT science papers, but none are genuine science papers, with all the data, endless charts, and messy higher math that is beyond my comprehension, and none of the publications are peer-reviewed journals. i may google the actual papers in question, but i have a long, long list of things to google already.

incidentally, i should add that i am Naomi Oreskes' survey is solid and has resisted attempts to refute it to my satisfaction. yep, i'll agree there's a consensus. four years later, probably even more scientists in relevant disciplines on board. all articles and press releases do, though, is add to the weight of how many scientists say AGW is happening. i already know there are lots of 'em. but consensus ain't how science works.

i am trying to understand what the science that has been done is saying, not the scientists who do it, however well-intentioned and convinced they may be. i want to see the actual work. therefore, i want to see the science papers that are doing the heavy lifting towards establishing AGW (or some other cause for GW) as i struggle to understand what's going on.

it's probably apparent by now that unless a shocking paper surfaces that slices, dices and even makes julienne fries, i'm unlikely to be convinced either way next week or even next month, and i don't know how long it will take. i don't make policy decisions so the world will not be on pins and needles while i make up my mind.

not that y'all need to jump around to entertain me, just clarifying my position. but speaking of jumping around, i think more people should at least try to direct all that energy they expend jumping toward looking at the actual science behind it, even if (like me) you've got a snowball's chance in hell of actually understanding it.

got more recent stuff? and are there science papers backing these people up? granted i wasn't there but i don't get the impression that these ideas were widely accepted and researched by scientists; looks more like a few outliers cashing in on our instinctual desire to thrill at being scared.

I was there (Boomer, Class of '54), and it was mostly taken up by the younger generation, the media on slow news days, and SF writers. I think every generation (as it enters adulthood) has the feeling that it's a defining generation, and Apocalypse Soon appeals to that.

It perhaps had some impact in China after Mao, but I think they did the math for themselves.

the appearance of the AGW scientific debate to a layperson--as opposed to net fora, where the appearance is shrill loons coming out of the woodwork--is that it will come down to these models consistently making accurate predictions. that still may not be enough for strict scientific fact, but my impression is it would add considerable weight to the hypotheses involved.

Some predictions from the few alternative hypotheses would also be useful. Accuracy of a single prediction is somewhat subjective. A cohort of predictions provide a more objective ranking.

my impression, also, is that given that climate is measured in 30 year chunks, it will take a while for predictions yea or nay to reach a critical mass.

It's a rolling thirty years, and the subject came up more than thirty years ago. I think the "thirty year" idea is more to do with the Hansen et al 1988 model and paper than climate science per se. That model is (in modern terms) fairly crude, and was only predicted to get into its full stride from thirty years on and forward. Of course, that doesn't mean it's all over the place for 29 years and suddenly snaps into place; it's done well enough over the last twenty years to not be discredited. Which is the best it could do, really.

More modern models, with vastly greater computing resources available and the lessons of earlier models to learn from, are not so restricted. Last summer, modellers at the Hadley Centre published predictions of what will occur in the next six or seven years. Which is bold.

if strict science vs trendy science is really happening, string theory may be headed for a world of hurt, huh?

The destiny (so far) of every Theory of Everything.

i've been critical of the other side, too--someone made the absurdly irrelevant claim that anti-AGW types need to "get out more" as if going outside and seeing your petunias bloom earlier every year would settle anything (disclaimer: i obviously know nothing about gardening).

I'll accept "irrelevant" as in your terms of scientific papers, but it was by no means absurd or irrelevant in its original context. Damned if I recall which thread it was in or when, but a bit of anecdotal was called for at the time. People are arguing that "global warming stopped in '98" on the basis of graphs and statistics; hundreds of millions of anecdotal experiences say otherwise. The Bali Conference and up-coming Copenhagen Conference say otherwise. The Bush White House fighting-retreat says otherwise.

Science isn't the only evidence worth discussing. That's what you want to concentrate on, and I'm fine with that. Leave me to plough my own furrow.

my "policy" position would be summed up:

I don't even go there. What's the point? There won't be any policies that aren't reactive, and we can't predict who'll be reacting when to what.

Stick to the science, is my advice. Policy is a diversion, and we know how some people love diversions.

that's all pop stuff though. speaking for myself, i'm not interested in pop stuff because that sort of thing would happen anyway, as it presses our instinctual buttons. it has no bearing whatsoever on whether the claims have anything to do with reality.

got more recent stuff? and are there science papers backing these people up? granted i wasn't there but i don't get the impression that these ideas were widely accepted and researched by scientists; looks more like a few outliers cashing in on our instinctual desire to thrill at being scared.

Can't help you. I wasn't arguing that the Malthusian stuff is fact or not and it's been over thrity years since I ran into the Population Bomb stuff. If you want to research that scare, I'm sure you'll find at least some discussion among accredited scientists. However, most of that was retrospective as to why the predictions didn't happen. To my knowledge, there has never been a formal academic refutation of Malthus.


which is why i'm here. "show me." i'm not necessarily looking for a highly technical discussion, but i do need one rooted in science, and i'm hoping for more pointers to toward actual research papers. seems to me that any skeptic worth their salt would want to see the [scientific] case in matters of science, and at least try to understand what's being said.


All that either side has right now are random observations that either support or rebut an unfalsifiable hypothesis. There are lengthy bibliographies availabe on the web for the separate studies. The interpretation is the crux of the controversy.

most of the shrilly irrevant posters on both sides are howling like mad dogs because AGW IS what one generally refers to as "post-normal-science"---policy decisions attempted before the science is settled. by its nature it will attract more partisan loons on both sides than anything else.

If you are stating that there's more politics about this controversy than science, I am in full agreement.


i suppose my "science" position at present can be summed up as follows:
it is apparent to me that the science isn't settled. it appears, from the papers i've skimmed, that there IS an anomalous climate shift, that hasn't been easily explained away by the usual influences on climate. "global warming," in other words, appears to me to be happening, although "climate change" is a more apt term. the permanence, cause and degree of this change are not settled as far as i can tell. AGW seems to my untrained eye plausible enough but NOT in any way "proven."


You're going to have to define for me exactly what you mean by "the usual influences on climate". I'm convinced that there is no one who really knows exactly what influences climate other than the sun. If such were known, I think that it would be rather easy to model climate. All you would have to do is apply different weights to each component and you'd have a fairly precise model in no time. That hasn't happened yet.


my "policy" position would be summed up:
it may be possible that as the pro-AGW crowd assert, that the problem is something we should start fixing before it is settled, but i'm frankly not sold on that yet at all. that said i'm inherently for alternative fuels as dependence on 'foreign oil' is a bad thing, i'm tentatively for nuclear power, "sustainable" architecture, fuel efficient transportation and clean rather than dirty coal technology regardless of AGW.


I'm all for the cessation of all types of pollution as quickly as possible. I just don't like to see science used as the whipping boy for trendy pseudo-science. It may be OK to force people to do stuff based on fear of putative AGW but sliding into pseudo-science eventually kick our asses more thoroughly than AGW would, if it is or isn't real.

NASA Goddard Center (http://www.nasa.gov/centers/goddard/news/topstory/2006/troposphere_ozone.html), March 2006
NASA scientists have found that a major form of global air pollution involved in summertime "smog" has also played a significant role in warming the Arctic ... According to this new research, ozone was responsible for one-third to half of the observed warming trend in the Arctic during winter and spring. Ozone is transported from the industrialized countries in the Northern Hemisphere to the Arctic quite efficiently during these seasons.


This one is fascinating. Ozone is now more contributive to AGW than CO2. While ozone is nefariously wiping out the poles, it's doing flat zip to warm the cities from whence it came. Varwoche, I would take this one off the list.

As far as the others, I haven't read most of them but, from the descriptions, I would say "Post hoc, ergo propter hoc." I dislike directed science. DDT and eggshells (what else was in them shells?).

Another CD claim out of the blue: AGW accounts for the urban heat island effect. Evidence?


Directed Science? Directed how?

Directed science: studies incorporating a known bias performed to confirm a conclusion rather than test an hypothesis.

Science has never prospered where it's been directed. What on Earth are you suggesting? Some unseen global power that can direct science?

So much to learn; so little time, huh? Know you not of any falsified studies? How did your cave get internet service?

Post-predicted hoc is often quite validly associated with propter. That's how science works. Observe, hypothesise, predict, observe again. Mystic science, the "something might turn up" position, really doesn't fit in there. AGW does.

Your imaginary view of science is showing again. Science is NOT observe, hypothesize, predict, repeat. That's what I call the iterative stochastic approach and it's not science. It might be where you live but not here on Earth. Science is hypothesize, devise a test, test, judge results. It's not science if the test cannot falsify the hypothesis. Your approach is called research/hypothesis formation and it's only a small part of science.

Again, you use the mystic science label. Can you explain to me yet, if all the science needed to model climate is known, why hasn't it been successfully modeled in over one hundred years of trying? After that, you can back up your claim that past climate can be post-dicted with the simple physics you know. How about your claim that a model is not a hypothesis? What fun, living in a make-believe world!

Not nearly as much as being fooled by irresponsible conclusions, varwoche. From where I sit, researchers can determine (1) if there is a correlation between overall climate and a natural phenomenon and (2) the approximate concentration of carbon dioxide in the atmosphere at that time. There is no authoritative method of linking them at the moment.

As it happens, one prediction - more than three spatial dimensions - may be falsifiable by the Large Hadron Collider when it gets up to speed (which is quite some speed, I can tell you :)). It may be able to at least put an upper limit on the number of spatial dimensions; if that limit turns out to be three then string theory becomes more of a hobby interest than a scientific pursuit.

maybe it's easy for you, but maybe i just suck at math and so when i look at the relevant equations or the mathematical reasoning behind the models i get a headache.

That level of math is beyond me, but I can usually get the drift. Partial differential equations is about where my maths education stopped. I never studied statistics so I'm not at all good with that. The best book on statistics I've ever read is How to Lie With Statistics by Darrell Huff, so I'm not completetely disarmed.

I think a good grounding in thermodynamics is key to understanding climate. It's all about how energy flows through a system so as to maximise (within the system's constraints) the rate at which entropy is increased. When you look at it that way everything slips into place :).

Once you get into complex dynamic systems, such as fluids, the maths is inherently difficult. You need computers for even the simpler equations or it just takes too long, even for one point (or cell) in space at one point in time, with one set of initial conditions. You can see how the computations would increase exponentially when you introduce multiples of those. (I did this stuff over 35 years ago so I can remember only the basics.)


I think a good grounding in thermodynamics is key to understanding climate. It's all about how energy flows through a system so as to maximise (within the system's constraints) the rate at which entropy is increased. When you look at it that way everything slips into place :).

That would be a good start. Fluid dynamics is at least as important.


Do you know RealClimate http://www.realclimate.org/ ? That's a good source of links and references.
I agree.

Note: that site pretty much represents 'The Team', as Steve McIntyre refers to it, so anyone referencing it can expect attacks from the GWS crowd.;)

Another CD claim out of the blue: AGW accounts for the urban heat island effect. Evidence?

Do what now? :confused:

You stated that ozone isn't warming the cities its generated in. Which implies that there's no extra warming in cities, ergo no warming bias introduced by the Urban Heat Island effect. Unless you think there's some cast-iron way of separating the two effects and the ozone contribution is nil.

Directed science: studies incorporating a known bias performed to confirm a conclusion rather than test an hypothesis.

What is this known bias, who knows about it, and how do they know? As one who's clearly in the know you could enlighten us.

So much to learn; so little time, huh? Know you not of any falsified studies? How did your cave get internet service?

To repeat myself, science has never prospered when it's been directed. The Nazis rejected "Jewish science", the Soviets under Stalin rejected genetics, the Catholic nations rejected free thought in general. Check out how things worked out for them.

Climate science, on the other hand, is prospering. There's no sign of the dead hand of conformity holding it back. More and more scientists and institutions around the world are getting involved, more and more funds are available, more and more attention is attracted to it.

Your imaginary view of science is showing again. Science is NOT observe, hypothesize, predict, repeat. That's what I call the iterative stochastic approach and it's not science. It might be where you live but not here on Earth. Science is hypothesize, devise a test, test, judge results.

How does that differ from my cycle?

OK, I start with observe, because observation precedes any hypothesis. The hypothesis (if it's useful) leads to a prediction of something as yet unobserved. Then it's back to observation, to see whether what's predicted is actually what's observed. That may require an experiment, or it may require looking for a phaenomenon that has not yet been directly observed or measured.

Observe, hypothesize, predict (devise a test), observe (test). The hypothesis is judged on subsequent observations.

It's not science if the test cannot falsify the hypothesis. Your approach is called research/hypothesis formation and it's only a small part of science.

AGW theory can be falsified quite easily. Global cooling would do it, absent other obvious influences such as major vulcanism or asteroid strike. We've had global warming, but if AGW theory is wrong it could as easily have been global cooling. Perhaps it has coincided with some other forcing, but that strikes me as extremely unlikely. One decade, maybe; two decades, it's a bit of a stretch; three decades and it's good enough for me.

Again, you use the mystic science label. Can you explain to me yet, if all the science needed to model climate is known, why hasn't it been successfully modeled in over one hundred years of trying?

For most of that time there were no computers, which was something of a handicap, but Hadley Cells were modelled on paper back in the 18thCE. Respect to Hadley, and to Coriolis, and, of course, to Arrhenius and Milankovich. Among others.

Sticking to the era of active modelling, Hansen et al 1988 has done a pretty good job, and you're in no position to say that recent models aren't accurate. The data's not in yet.

The science involved is fairly simple, but the application is a bitch. A thin film of fluids on a rotaing sphere orbiting a fixed energy source that's not quite normal to the axis of rotation. And that's without bringing geography into it. Modelling the broad picture counts as a success in the circumstances

After that, you can back up your claim that past climate can be post-dicted with the simple physics you know.

What non-simple physics are you suggesting? Dark matter? Dark energy? Dark climate-specific-stuf? There's been no call for it so far.

How about your claim that a model is not a hypothesis? What fun, living in a make-believe world!

Let us know how that works out for you in the long-run.

A model is not a hypothesis. It's a representation of a hypothesis, a test of a hypothesis, if you will. Models are tools, just as telescopes and microscopes are tools.

I would wonder what a great number of scientists are doing in the world these days. They are working with many areas where it is impossible to 'falsify' their research. String theory and astronomy and other areas of research come to mind. Not everyone has the luxury of a laboratory.

If it's impossible to falsify research then it's not even at the hypothesis level yet. To have a hypothesis that will eventually be accepted as a theory, it must be falsifiable. No mention of labs, cyclotrons, etc need enter into this discussion.

Why is it that perfectly rational and intelligent people want to give the AGW hypothesis a pass on this part of the scientific method? Is it fear that waiting too long will doom us? Maybe so, but the scientific method got us this far and I say let's stay with the thing that got us here. I'm very skeptical that the scaremongers using AGW for their agenda are correct anyway.

Prove is too strong a word. There's lots of things that are widely accepted but can't be proven.

Did my wording offend you, varwoche? I so humbly apologize. Could you, pretty please, sir, point to a falsifiable link between the mean concentration of carbon dioxide in the atmosphere and Earth's heat content? When you get a chance, that is. Don't break a sweat!

And since you dismiss scientific evidence out of hand without even reading it, and since you scare-quote "climate science" as if it's not real science, I see no point in jumping through hoops on your behalf. Sorry 'bout that.

I've dismissed the claims of one of your links on exactly the point I challenged you on. I read the summaries of the others and noted that they too appear to suffer from the same flaw. That flaw is presupposing that carbon dioxide is indeed a major temperature driver. So, yes, I will disbelieve any statement using that assumption for now. I will not dismiss the raw data those studies turned up without a good reason, though, as raw data is different from interpretation.

You don't surprise me or disappoint me by refusing to meet my challenge, varwoche. Sorry 'bout that.

Once you get into complex dynamic systems, such as fluids, the maths is inherently difficult.

It's practically impossible is on the small scale, but on the large scale (and climate is pretty large) the chaos fades away. The fluid dynamics of a wave breaking is still uncertain (or was last I heard), but an experienced surfer can pick out a pattern in very short order.

You need computers for even the simpler equations or it just takes too long, even for one point (or cell) in space at one point in time, with one set of initial conditions. You can see how the computations would increase exponentially when you introduce multiples of those. (I did this stuff over 35 years ago so I can remember only the basics.)

Even with today's resources models operate on atmospheric cells that are a hundred or more kilometres across and a kilometre deep. A lot of fine detail is going to be lost in there. To my mind the most important lost detail is clouds, which exist generally on a much smaller scale. Cloud-effect has to be averaged across the cell, and that's a definite weakness.

That would be a good start. Fluid dynamics is at least as important.

It's certainly important. On the other hand, thermodynamics does inform fluid dynamics, and so takes precedence IMO. (I was proselytised by a thermo-dynamicist at an impressionable age. Given any new subject I always start from that perspective. "It's the entropy, stoopid".)

Interestingly, thermodynamics and fluid dynamics are both strongly grounded in the 19thCE. This is old, well-established science. And well-resourced at the time, since they pertain so strongly to steam-based technology (the cutting-edge of the day).

It's too precious how, when it suits you, you verbalize the problem with establishing AGW (resolution of the natural and anthropogenic effects) yet, usually, you dismiss the natural component to bolster your belief in AGW. Well done.

Climate science, on the other hand, is prospering. There's no sign of the dead hand of conformity holding it back. More and more scientists and institutions around the world are getting involved, more and more funds are available, more and more attention is attracted to it.

I have no idea what you're trying to say. Are you making that claim that, because it's popular and well-funded, some climatologists won't succumb to tempation for fame, honor and wealth? Let me know how that goes, will you? Those are usually the ingredients needed for corruption.

Is English not your first language? Since when does observe mean test? You really need to review your science. You've got it upside down, inside out and backwards. I don't fall for that stuff. I don't care what you mean if what you say is diametrically opposed to it. Why do you rely on hand-waving when understanding the scientific method is so damned easy?

AGW theory can be falsified quite easily. Global cooling would do it, absent other obvious influences such as major vulcanism or asteroid strike. We've had global warming, but if AGW theory is wrong it could as easily have been global cooling. Perhaps it has coincided with some other forcing, but that strikes me as extremely unlikely. One decade, maybe; two decades, it's a bit of a stretch; three decades and it's good enough for me.

You've amazed me again. First you call it the AGW theory. Just couldn't resist, huh? Sorry, bub, it's a hypothesis, if anything, and I'm being generous. As it can't be falsified yet, it's not even that. Strictly, it's more of a thought experiment that will someday lead to a hypothesis.

I've taken you to task previously for the statement that a cooling world would falsify the AGW hypotheses. That is not true and you only say it because you don't know much about thermodynamics. The AGW hypotheses are proposed mechanisms which try to describe how human activity has influenced the planet's climate. Not only are these hypotheses not yet falsifiable as to their intrinsic correctness, there is no indication as to how efficacious each proposed mechanism will be. That is, AGW gases may indeed warm the earth but a stronger climatic mechanism could cause cooling while AGW is occuring. That is, AGW may indeed be active even when the planet is cooling. Remember my tellng you about not making your k's? There is nothing to rule out that k[climatic factor n] >> k [AGW].

I know what's simple here and it's neither the science nor its application. I am telling now that your belief that all the necessary science that needs to be known to understand climate is already known is absolute nonsense. That's a permutation of "the science is settled" gaffe. I would tell you right now that, given the time, money and power that has been pooled into trying to model climate without success, your premise that all we need to know is known gets less and less likely every day. Whereas we have the mathematics to deconvolute tremendously complex matrices of intertwined signals, you keep retreating into the tired argument that "we have to wait just a little longer" while some other fool is telling me that "there's no time to wait".

A model is not a hypothesis. It's a representation of a hypothesis, a test of a hypothesis, if you will. Models are tools, just as telescopes and microscopes are tools.

Computers are tools. Models are hypotheses. Some models are even theories. Every physics equation you ever saw in your life is a model. For some reason, you've convinced yourself that models only belong in computers or catwalks. T'aint so.

Really, you need to go back to remedial science class. Nothing you say makes sense. If you want to believe in unfalsifiable stuff, fine. No one's going to object. Just don't try to blame science for it.

On falsifying the AGW hypothesis. M. Tobis, a climate modeller had this to say: (http://initforthegold.blogspot.com/2008/02/first-big-surprise.html)
R. Pielke Jr. asks at what point the theory on which we operate might be falsified. I have to say I have a hard time answering. If this means falsifying the theory of the greenhouse effect, it's baffling. The question is sort of like what it would take to abandon the idea of gravity. It is pretty much incomprehensible to me how the theory of radiative transfer might be falsified without taking the whole of science down with it.

While Lucia, well, I think she is an engineer, had a different take on it.
“What trend in GISS Land/Ocean temperatures over the next 5, 8 or 10 years, would be inconsistent with the most recent IPCC projections of climate change?”

This question can be answered, because it nails down a metric– GISS Land/Ocean, and specifies the “current consensus” with projections that are published, and, so, knowable. The answer is a bit complicated, since the IPCC provided a range of projections, described the probabilities in somewhat vague terms and has different projections for both short and long terms trends.

In my opinion, the short answer to the question is: If, the weather is such that an ordinary least squares fit to GISS Land/Ocean data for the next decade shows any negative trend, this would be inconsistent with the IPCC’s short term projection for temperature which appears to be 2.0°C per century.
You can read about it at the links below.
http://rankexploits.com/musings/2008/what-weather-would-falsify-the-current-consensus-on-climate-change/
http://rankexploits.com/musings/2008/can-ipcc-projections-be-falsified-sample-calculation/
http://rankexploits.com/musings/2008/yet-more-on-falsification/

I like Lucia's approach, in as much as she defines a metric to use and it would be obvious if temperature increases meet the demands of the hypothesis or not. Its clear and straightforward.

There is clearly a difference between the two viewpoints. For a climate modeller, when expressed in very elementary terms, the AGW hypothesis may simply be a question of radiative transfer. Increasing the CO2 content is expected to lead to warming, so for a climate modeller, this aspect is fundamental to the work that they do. The rate of warming is what is in question: given a doubling of CO2, what will happen? Falsifying AGW requires falsifying some basic physics. Lucia defined her falsification criteria differently. Her test is applied to the model outputs, the predictions the modellers make of 'what will happen'.

In really simple terms, and I do like things simple, AGW would be falsified for me if CO2 doubled and nothing happened. Or, what are we up to now, increased by a third and nothing happened. I suspect that for that to be true, some physics that I admittedly don't well understand will need to be either just plain wrong or to have been wrongly applied for a heck of a long time; or some unknown mechanism will minimise the effects of the CO2 increase.

In that sense, falsification of AGW seems quite straightforward to me. Nothing needs to happen. But I think we often talk at cross purposes. What is implicit to a climatologist is not implicit or obvious to an engineer or, e.g. a JREF forumite. Slimething, you aren't the only one out there wondering about falsification. Its an important question.

And demonstrates some balls. I too like that approach.

What struck me was this from Pielke Jr :

"What behavior of the climate system could hypothetically be observed over the next 1, 5, 10 years that would be inconsistent with the current consensus on climate change?".

So there is a current consensus, and we've the word of a Pielke to back it up with. Cool.

(That "1, 5, 10 years" is the antithesis of "ballsy". What a wimp.)

From the third of your links -

Now, as it happens, I don’t like to use already collected before a prediction to test a prediction. I don’t like that the IPCC does that. But, oddly enough, the IPCC seems to do this all the time, and includes already existing data in their predictions. So….
if you think calling the IPCC’s “2001-2010″ predictions, made in 2007 ‘predictions’ even including the eariler data is fair, and
if the IPCC would normally use this 2001-2007 data to “confirm” their “prediction”, made in 2007
then, it is, in some sense, fair to falsify their “predictions”, based on the same data the IPCC would use to confirm their predictions.As you can see, the current Hadley trend is flat, flat, falt.
So yes, if the flat trend in Hadley data persists to the end of 2010, that would be inconsistent with projections of the predicted 2.0C/century trend. Only lower rates of increase would be consistent with the actual weather to a 95% confidence level.

Support for David Rodale's assertion that in the last decade, it has not been warming.

You've posted links to articles that can't be retrieved without payout $, knowing that people would not pay the $ out. Your summaries of the articles content may or may not reflect the actual scientific conclusions.

Consider, for a moment, how often I've posted an article that clearly cut into the AGW-warming point of view, and how it got picked at based on nuances of grammer or the politically correct AGW disclamer contained therein. The ability of persons such as yourself to produce such (weak) criticisms was based on my providing articles for which the full pdf was available without charge.

If you cannot (or will not) do the same, don't expect your spin or the spin of others regarding the actual conclusions of the scientists writing the articles to be considered as fact.

Pseudoscientific Varochian Neo-Alarmism noted. I know I'm going to regret this, but I have to ask - what's the difference between 'alarmism' and 'neo alarmism'? Did you merely note that some libbies use 'neo-conservative' in a deregatory way and think it sounded cool, or is there some sort of point?

Well, just start with Andrew's list.

That should keep you busy for a while.:)

there's a lot of crap on there. if i haven't already said i'm not interested in shameless political hacks like Miloy. let me make it perfectly clear right now: "JUNK SCIENCE" is a complete waste of bandwidth.

also, forget anything with "hoax" in the title; i don't own a tinfoil hat and don't plan on one. like most conspiracy theories, all the climate conspiracy theories i've seen are pretty loony. i've read papers by some of the more controversial pro-AGW scientists--Hansen for example--and while they may be wrong, and a lot of people may still agree with them, that ain't enough to call it a conspiracy. the stench these sorts of arguments give off is exactly why i'm calling for credible, science-based blogs critical of AGW. it's not that i believe conspiracies never happen; Enron was real. but hey i'll gamble and risk missing something good by ignoring all conspiracy theories thanks. it's a risk i'm willing to take, tinfoil isn't my color thanks.

now if you wouldn't mind winnowing out the conspiracy nuts and political hacks and limiting it to AGW-SKEPTICAL science-based blogs, i'm still interested. incidentally, "real climate" is full of scientists, true--but pretty strongly pro-AGW. pro-AGW science blogs are easy to find.

If it's impossible to falsify research then it's not even at the hypothesis level yet. To have a hypothesis that will eventually be accepted as a theory, it must be falsifiable. No mention of labs, cyclotrons, etc need enter into this discussion.

Why is it that perfectly rational and intelligent people want to give the AGW hypothesis a pass on this part of the scientific method? Is it fear that waiting too long will doom us? Maybe so, but the scientific method got us this far and I say let's stay with the thing that got us here. I'm very skeptical that the scaremongers using AGW for their agenda are correct anyway.

Slime, AGW theory requires a "hotspot" in the middle troposphere levels, this hotspot being most pronounced in the tropics due to radiative effects being the most pronounced. As I have presented research which shows this hotspot does not exist, or arguably exists but is a faint shadow of what AGW theory would require, it seems that at here is a hypothesis of AGW that has been refuted pretty nicely.

Derogatory? No, to the contrary. Unlike 90% of the Warmologists posting at JREF, Varoche makes a serious effort to find literature to support AGW.

i asked for:

you even quoted it in your response.

yet you regurgitated a list so random that it included not only Miloy, but freakin' "Real Climate"? you're aware they're pro AGW???? apparently not.

maybe you'd better sit down for this.... this may shock you.... but i *can* google. no really, i can. seriously.

point of my request was that, if anyone had done *their own* homework and found the kind of resources i was looking for, and if they are interested in sharing them, i'm interested. with all due respect, is there any reason i should expect the rest of your thinking to be any less sloppy and haphazard?

From the third of your links -

Now, as it happens, I don’t like to use already collected before a prediction to test a prediction. I don’t like that the IPCC does that. But, oddly enough, the IPCC seems to do this all the time, and includes already existing data in their predictions. So….
if you think calling the IPCC’s “2001-2010″ predictions, made in 2007 ‘predictions’ even including the eariler data is fair, and
if the IPCC would normally use this 2001-2007 data to “confirm” their “prediction”, made in 2007
then, it is, in some sense, fair to falsify their “predictions”, based on the same data the IPCC would use to confirm their predictions.As you can see, the current Hadley trend is flat, flat, falt.
So yes, if the flat trend in Hadley data persists to the end of 2010, that would be inconsistent with projections of the predicted 2.0C/century trend. Only lower rates of increase would be consistent with the actual weather to a 95% confidence level.

Support for David Rodale's assertion that in the last decade, it has not been warming.

It's just a shame for DR that the data doesn't support his assertion.

Whether I agree with your specific comments or not, this is the same standard of critical examination that should be applicable to Varoche's linked papers with their ostensible assetions.

Except that I provide the source material to allow such critical discussion.

Thanks for making my point.


And since you dismiss scientific evidence out of hand without even reading it, and since you scare-quote "climate science" as if it's not real science, I see no point in jumping through hoops on your behalf. Sorry 'bout that.

Yep, well, who knows, varoche. Maybe some of those links do support your radical non mainstream view of AGW, but no one will ever know, because no one is going to go pay $9 - 35 per article to find out, will they?

You are welcome to produce links that link to actual scientific papers and have them considered on their merits or lack of. Indeed, linking directly to peer-reviewed papers is the ideal. Unfortunately, as you know, papers that are available online for free are in the extreme minority.

This means that we often must link to indirect sources. And obviously, we must always take into account the possibility that the science is not accurately portrayed. For this reason, it's important to link to unbiased sources as best we can and avoid sources that willfully twist the facts.

This of course is the worst case scenario -- citing agenda-driven, non-expert propagandists who are proven liars. This could aptly be described as the mhaze scenario (http://forums.randi.org/showthread.php?postid=3075882#post3075882), and it has no place on a skeptical forum.

My point is that no one is going to pay $9 - 35 to refute or read an article, including you. But that doesn't make the poster's assertions as to it's comments (or his cut and paste of someone else's assertions as to it's comments) authoritative. It's his job to substantiate the assertions, either by producing the actual articles, substantial excerts from them, etc, whatever would do the job.

Just produce the documents that you think support your case, whatever you think your case is.

It's really pretty simple. There isn't any need for a lot of chatter and personal attacks, unless you actually don't have much to produce.

seems like, as a deeply entrenched anti-AGW, you'd be eager to show that rational people are skeptical of AGW rather than resorting to documentaries with spooky music like a 9-11 troofer. but i guess 'deeply entrenched' trumps 'rational.'

i may never have a list, but here's the thing: if someone asks for a cheeseburger, and i don't have one, i don't give them anything. and i definitely dont give them a dog diarrhea sandwich.

hey! nice cliche! *yawn*.

i thought maybe, just maybe, i thought you'd notice the difference between "beggers" (sic) and giving you a chance to augment your case against AGW (rather than, oh i don't know, make it clear your tinfoil hat is more than a fashion statement).

have to agree with that. a context like this, 'theory' should be used rigorously. 'evolution' is a theory in the scientific sense (as i understand it; i'm not a scientist). AGW is a hypothesis at this point.

i do find this to be an important distinction.

Hawking's views are pretty out there; day-after-tomorrow type stuff.

Yes, but that wasn't why I told the story. The point was that a "sceptic" said that he respected Hawking and was sure that someone that clever wouldn't be taken in by AGW. Yet, when I presented the evidence of Hawking's actual views, did the sceptic reconsider his own views? Did he hell! He then shifted to claiming that Hawking couldn't have really looked at the subject. This is denialism, not scepticism, and it infests this subject.

Hawking has also said that one way or another we could possibly really mess the planet up, and we needed to progressively develop ways to get a part of the human race permanently off planet. In this context he was mainly talking about designer bugs. (just to put his remarks in a wider context).

Slime, AGW theory requires a "hotspot" in the middle troposphere levels, this hotspot being most pronounced in the tropics due to radiative effects being the most pronounced. As I have presented research which shows this hotspot does not exist, or arguably exists but is a faint shadow of what AGW theory would require, it seems that at here is a hypothesis of AGW that has been refuted pretty nicely.

Not you too, mhaze! Please repeat after me: hypothesis, not theory. (Slime curls up in fetal position.)

What I consider to be primal to the AGW thought-experiment is that artifacts, any artifacts, are systematically warming the planet. I can't argue that it's not happening because the mere existence of blacktop where there once were trees would make that true in a trivial sense. I have not examined the various popular hypotheses as you have so I don't know of the hot-spot you speak of is common to all variants of the greenhouse gas AGW hypotheses. I doubt it is so, for the moment, let's say that one or several hypotheses requiring the formation of a hotspot have been falsified on the basis of one false prediction. However, there must be some hypotheses that don't predict that so AGW hypotheses are still alive.

I have noted before that, based on the physics underpinning the basic concept of greenhouse gases adding insulation and thus warming the planet, I believe that the hypotheses are probably true but not proven. I am begining to reach the opinion, though, that such signal as AGW is generating is weaker than first expected and may be unresolvable for quite some time. We'll just have to wait and see.

quite familiar with the Huff book and the principles contained therein. used to do graphics in an investment bank, and boy did those people use every trick in the book!

:D

When PC's and spreadsheets and graphics and cheap printers and PowerPoint came in ... I was already primed to advise people on what chart option to select depending on the intention. It's been a valued part of my toolkit since I was a teenager.

yeah, i have ample blog resources on the 'yes AGW' side. still keenly interested in links to any papers though. the IPCC report is de facto a policy recommendation, what i'm interested in is scientific papers attempting to establish the A in AGW.

IPCC reports are packed with references in the scientific parts. The primary task of the IPCC is not to recommend policy but to collate current scientific research and understanding, for the benefit of actual policy-makers. That's where the meat is.

for blogs, etc i'd be interested in CREDIBLE 'no AGW' material, because all i can find is partisan horse droppings by zero-credibility political hacks like Steven Miloy, the Ann Coulter of science.

It's a bit of a give-away, isn't it? The GW Sceptic presentation reeks of defensiveness, the consensus presentation doesn't. Only one side is associating themselves with such scoundrels. Only one side is shrill and often at least borderline hysterical.

My point is that no one is going to pay $9 - 35 to refute or read an article, including you. But that doesn't make the poster's assertions as to it's comments (or his cut and paste of someone else's assertions as to it's comments) authoritative. It's his job to substantiate the assertions, either by producing the actual articles, substantial excerts from them, etc, whatever would do the job.

Just produce the documents that you think support your case, whatever you think your case is.

It's really pretty simple. There isn't any need for a lot of chatter and personal attacks, unless you actually don't have much to produce.

Lake Qinghai on the Tibetan Plateau Reference
Xu, H., Liu, X. and Hou, Z. 2008. Temperature variations at Lake Qinghai on decadal scales and the possible relation to solar activities. Journal of Atmospheric and Solar-Terrestrial Physics 70: 138-144. What was done
Working with sediments retrieved from Lake Qinghai on the northeastern Qinghai-Tibet Plateau, the authors reconstructed a 600-year temperature history of the region based on high-resolution series of the sediment's total carbonate content, the δ18O and δ13C of its carbonates, and the detrended δ15N of organic matter contained in the sediment cores, which they compared against total solar irradiance histories reconstructed from sunspot numbers, and tree-ring 14C and ice-core 10Be data that are also indicative of solar activity.
What was learned
Xu et al. report that their temperature history indicates that "the intervals of 1430-1470, 1650-1715, and 1770-1820 are consistent with the three coldest intervals of the Little Ice Age," and that "these obvious cold intervals are also synchronous with the minimums of the sunspot numbers during the past 600 yeas," namely, "the Sporer, the Maunder, and the Dalton minimums," which facts strongly suggest, in their words, "that solar activities may dominate temperature variations on decadal scales at the northeastern Qinghai-Tibet plateau." In addition, their observation that "more and more evidence indicates that the Little Ice Age occurred worldwide," provides more and more evidence that it was likely solar-induced.
What it means
If the development of the significant cold of the worldwide Little Ice Age was driven by a concomitant change in some type of solar activity (which seems fairly well proven by a wealth of real-world data, of which the study of Xu et al. is but one example), it logically follows that the "undevelopment" of the Little Ice Age (i.e., the global warming of the 20th century) was primarily driven by the reversal of that change in solar activity, and not by the historical rise in the air's CO2 content. However, as also noted by Xu et al., how small perturbations of solar activity have led "to the observed global warming, what is the mechanism behind it, etc., are still open questions." Nevertheless, everything else about the matter seems fairly well established.

problem is, the word "theory" has a different yet completely legit meaning in the wider world. as a parallel, no doubt analytic philosophers cringe whenever they hear some layperson say things like "my philosophy of life is you reap what you sow."

iv'e even heard scientists occasionally make this usage error (usually outside of their field, heh). nonetheless it is very much worth preserving its specialized meaning within science; look at the grief abuse of the word has caused in the hands of creationists!

so in short, it's a fussy point true, but 100 percent cringe-worthy. and a lot more important of a distinction than the specialized use of "philosophy." maybe we need a new word for "scientific theory"....

That is exactly what I've been saying but in too verbose a manner, AUP. Thank you for clarifying it. I agree with the the physics underpinnings.

Britain's Prince Charles Compares Global Warming to Nazis

Wednesday, May 02, 2007
http://www.foxnews.com/images/service_ap_36.gifLONDON — Britain's Prince Charles (http://javascript%3Cb%3E%3C/b%3E:siteSearch%28%27Prince%20Charles%27%29;) said Tuesday that urgent action is needed to fight climate change, likening the struggle to Britain's battle against Nazi Germany in World War II.
The environmentalist prince told a business conference at his St. James's Palace residence that "the crisis of climate change (http://javascript%3Cb%3E%3C/b%3E:siteSearch%28%27climate%20change%27%29;) is far too urgent and discussion simply isn't enough."
"I do not want my children and grandchildren, or anyone for that matter, saying to me, 'Why didn't you do something when it was possible to make a difference and when you knew what was happening?'" he said.

"We can do it, just think what they did in the last war. Things that seemed impossible were achieved almost overnight."
The 58-year-old heir to Britain's throne is a firm supporter of environmentalist causes, and runs an organic farm on his Highgrove (http://javascript%3Cb%3E%3C/b%3E:siteSearch%28%27Highgrove%27%29;) estate in western England. He also has a multimillion-dollar line of organic foods, Duchy Originals, whose profits go to charity.

Especially to those of us most concerned with the science not being done. Time and time again you fail to answer challenges to this line of thought that you keep touting. I assume this vague statement relates back to this whimsical gem: It's quite clear to everyone who's paying attention that they've hung their hat on carbon dioxide. ... But, everything from this point forward is geared at bolstering that assertion and making any observations fit that premise, instead of considering alternate possibilities. I've talked about this extensively already. No need to rehash now. Apparently you're not following the state of the science or even the thread(s). Otherwise you'd be aware that your claim -- consisting of pure speculation that you've failed to provide an iota of support for -- is abject nonsense:

study about the sun (http://news.nationalgeographic.com/news/2007/07/070712-sun-climate.html)

Huh? What challenges? I'm not the one making specific claims. I am the one challenging people to do additional science that will either prove or disprove their current claims.

Science - it's quite simple - is the unbiased collection and assimilation of facts that help to elucidate something meaningful and predictive about a particular area of interest. There are many ways to remove bias from this process, none of which I've seen consistently employed to date.

To that end, all I've asked is that the people looking at retrospective data, and making broad, sweeping statements about the accuracy, meaningfulness, and validity of those data, use more rigorous methods to either further prove or disprove their conclusions.

Specifically, I would like to see two things:

1) Controlled experiments where the microfractions of CO2 being discussed demonstratively show a quantifiable heat-rentention effect on the order of magnitude now being attributed to current AGW models.

2) A prospective, blinded study of dendrochronology controlling for other mitigating factors that would validate the current historical temperature record.

These are two very easy experiments that could be started today. The first one could be done in an afternoon. The second one may take a decade (or so), but would demonstrably make the point about the effect of CO2 - either way.

Why won't these researchers do these experiments? I've heard a lot of excuses why they won't, but still no one is doing them. Funny.

I don't care about other "forcers" of climate change at the moment. Let's focus on CO2, upon which is the peg the majority of this debate's hat is currently hung.

PROVE THE PRINCIPLE! This has NOT adequately been done to date. Correlation does not equal causation. And, there has not definitively proven to be a causative link. (I feel like the only sane man in a crazy world. SHEESH!)

That you will never see.
For newcomers, AGWrs claim that the physics about their pet theory is very sound.....CO2 have some properties that make it a "greenhouse gas".

But......... the real question is : Those properties are still in effect when CO2 is in a 1000 PPM dilusion (almost homeopatic) on air? And what happens when this CO2 is stored in large masses of water?

There are some other questions, and AGWrs have come with nice theories about this, but a controlled experiment we haven't see.

yes, and when that 'single study' happens, it will inevitably be followed by lots of further research reproducing the result.

that's fair enough, for sure.

but the best way to CORRECT it is for posters like mhaze to stop posting even dumber, sloppier arguments. no offense, but DUH.

but looking at this forum--and let's be clear i'm NOT sold on the A in AGW--there are too many people on the skeptic side in this forum that just do a crap job of posting. if one paid no attention to the science, didn't give a rat's orifice about 'democraps' and 'republic***s', one would probably be put off by sloppy posts like mhaze's and inclined to trust more careful posters like Trueskeptic. damn shame too since it's utterly superficial.

Sincere question: when a field becomes as large (encompassing many scientific disciplines) and as mature ("greenhouse effect" was proposed in the 19th century), what single study could disprove GW or AGW? Those seem to be pretty big theories with many sub-theories and hypotheses. I could imagine someone proposing a seminal hypothesis that demonstrates a non-causality between atmospheric GHGs and global temperature, but that would then require many, many more studies to test, replicate, and verify it.

As an example, could any one single study disprove the Theory of Evolution now, after 150 years? Ok... I suppose finding "a bunny rabbit in the pre-cambrian" would disprove at least part of it, but would such a study be accepted without a great deal more studies to verify it?


That was my point. My new point is that when this failure is commited by an AGW believer most people don't notice it. No one has corrected Truesceptic dumb argument about Coulter, but the discussion about the counterargument is quite alive.

Oh, I don't know about that... I think that Greenpeace can often act idiotically, as can many other ideologic (as opposed to scientific) environmentalists, and I don't think that this is a secret among those who accept AGW as probable. Is it possible that there is a confirmation bias to your hypothesis that AGW "believers" (I don't agree with the framing of that point with the word "belief") get a free pass when it comes to their evangelism? I'm quite aware that I'm highly susceptible to confirmation bias of my assumptions!! :)

Fine. Let's put it in a bottle and do the test. Argued in principle. Why has no one proven it in practice?

Gibberish.

I've set out the experiment before, and will state it again. Select your trees. Place appropriately calibrated measuring devices near those trees. Let trees grow. Send tree rings to scientists in a blinded manner a set period of time from when the experiment was initiated. And, have them attempt to correlate the data in a blinded manner to the actual observations.

Not done yet. Why?

YES! i've seen a LOT more proAGW than noAGW science papers and granted i most likely don't fully understand the science, but all i'm seeing is correlations! normally i read evo bio papers (for fun, believe it or not). compare and contrast.

i don''t know enough about it to know what experiments *should* be done, but the stuff i have seen is suggestive, sure. but i've seen NO papers that'd convince me that AGW is a nailed-down theory, let alone that it's gonna be a disaster that we have to fix NOW before it happens or.... else.

and when i express my skepticism i get offered links to tinfoil-hat conspiracy theories from so-called skeptics. i expect the climate scientists are working in good conscience (unlike many internet posters and conspiracy nuts). but... there hasn't been enough time and enough research done to sort the wheat from the chaff. fads and trends hit science as much as any human activity, and until it's done and dusted we don't KNOW.

Torneträsk tree-ring width and density ad 500–2004: a test of climatic sensitivity and a new 1500-year reconstruction of north Fennoscandian summers (http://www.springerlink.com/content/8j71453650116753/?p=9ddaf2f63141459da7289ee7be4a4b41&pi=5)
Abstract
This paper presents updated tree-ring width (TRW) and maximum density (MXD) from Torneträsk in northern Sweden, now covering the period ad 500–2004. By including data from relatively young trees for the most recent period, a previously noted decline in recent MXD is eliminated. Non-climatological growth trends in the data are removed using Regional Curve Standardization (RCS), thus producing TRW and MXD chronologies with preserved low-frequency variability. The chronologies are calibrated using local and regional instrumental climate records. A bootstrapped response function analysis using regional climate data shows that tree growth is forced by April–August temperatures and that the regression weights for MXD are much stronger than for TRW. The robustness of the reconstruction equation is verified by independent temperature data and shows that 63–64% of the instrumental inter-annual variation is captured by the tree-ring data. This is a significant improvement compared to previously published reconstructions based on tree-ring data from Torneträsk. A divergence phenomenon around ad 1800, expressed as an increase in TRW that is not paralleled by temperature and MXD, is most likely an effect of major changes in the density of the pine population at this northern tree-line site. The bias introduced by this TRW phenomenon is assessed by producing a summer temperature reconstruction based on MXD exclusively. The new data show generally higher temperature estimates than previous reconstructions based on Torneträsk tree-ring data. The late-twentieth century, however, is not exceptionally warm in the new record: On decadal-to-centennial timescales, periods around ad 750, 1000, 1400, and 1750 were equally warm, or warmer. The 200-year long warm period centered on ad 1000 was significantly warmer than the late-twentieth century (p < 0.05) and is supported by other local and regional paleoclimate data. The new tree-ring evidence from Torneträsk suggests that this “Medieval Warm Period” in northern Fennoscandia was much warmer than previously recognized.
The article concludes the Arctic has actually cooled in the last 1500 years, and as we all know now (at least those that didn't assimilate) the recent ice melt was due to wind and oceanic circulation patterns and not temperature.
