Hansen revises and checks the figures, it's patent fraud, McIntyre does it for him, he's a hero. :rolleyes:
Not sure what patent fraud means in oz-talk, but it is accounting fraud according to the GAAP standards here. That's the national standards for accounting that are followed by all public companies.
McIntyre thinks scientists should be accountable for the accuracy of their data according to the GAAP standards. I concur.

I think you misunderstand what McIntyre was saying. He was saying Hansen can't change the measurement system he is using. As far as I can tell, hansen moved from a less accurate system to one that is more accurate. McIntyre was wrong in either case.

Only a gullible warmer could believe "adjusting" temperature data upward continually without justification or explanation is not to be questioned.
The trend is less than the climate models predicted, and it is going down. It won't be long until you folks will be back here trying to convince us that's a result of "global warming" as well. Irrefutable hypotheses are great aren't they?
Let's see. McIntyre continually trawls through Hansen's data, looking for errors. He's a hero. Hansens moves to a more accurate data set, he's a fraud. He can't win, because if he stayed with the old one, he'd be criticised for that too.
Meanwhile, you ignore the validation of Hansen's code by McIntyre. As did McIntyre. It was supposed to reveal all kinds of incompetence, but it didn't. I can't imagine the pressure Hansen is put under by this remorseless and merciless circling of the sharks, who only have the intention of eating him alive.
The troposphere is warming. At that rate, it's on track for the IPCC predictions. The first part is the warming of the troposphere, then the feedback mechanisms, which aren't to do with troposphere warming, take over.

By the way, AUP, you never answered me on this.
I said I was willing to go 0.025 C/decade for AGW superimposed on the natural cycle, with 0.005 C/decade for CO2 "greenhouse effects".
Do you want to agree with that? If not, please look at the chart here and tell me how much for AGW in the last decade, how much for CO2, and how much was from the natural cycle.
Here are some things to mull over. I'll be pointing out some details in them which are quite relevant to the current discussion. Not that I've got all the answers, mind you....just trying to make an effort to ask the right questions.
You don't have to ask me, the IPCC has already worked it out. Read the report.

Wrong and backwards. Hansen was wrong in either case. From the current main page....

Should NASA climate accountants adhere to GAAP?
There are undoubtedly more Climate Audit readers familiar with GAAP (Generally Accepted Accounting Principles) than at other climate websites, but it’s worth re-stating one of the fundamental GAAP principles (http://en.wikipedia.org/wiki/GAAP): Principle of the permanence of methods: This principle aims at allowing the coherence and comparison of the financial information published by the company.
Now you may say that this is “science” and accounting principles don’t apply. And my response would be that I’d expect GAAP principles to be a minimum standard for the type of climate statistics being carried out by NASA. Even if NASA climate statisticians are unaware of GAAP per se, they should be adhering to the principles. Sharp practice is sharp practice, however it is gussied up.

This curve fit has a pretty good correlation to
the general temperature rise due to coming out of the Little Ice Age
the known hot period in the 1930s
polar ice cycles of 60-80 years
the cool period from 1940-1970
the "alarming accelerating trend" since 1980Climate cycles accounts for all these major events and swings in the data.
The CO2 AGW cycle doesn't.
The CO2 AGW theory only explains the "alarming accelerating trend" since 1980. But I've asked here repeatedly if someone could just show a relationship between the CO2 level and the temperature, first with 1850, then 1950, then with the last 30 years. No takers. Why?
Because CO2 does not have a significant relation to temperature as measured. And that's the core premise of the IPCC. They are wrong.

I keep on thinking if I ignore anything Singer says, you'll forget about him.
The cooling after the 40's was due to pollution. It's already been researched. If you want to confirm it yourself, go to Bangkok. The pollution is so bad the sun is a red orb all day. It cools the city. The pollution drifts down to the some resorts, one of which I spent a few days at. Occasionally the haze would lift, and the temperature would shoot up.
It's got nothing to do with Singer, his cycles, or his support of big tobacco and big oil. Now it's warming again. Hadley is following the climate much more closely than other climate models have been able to, and it's going to start rising again very soon. You tip a drop in the next few years, I'm backing them and it's going to rise.

I gave you your opportunity to pick three annoying references. You declined, so now you get annoyed. Get over it. AGW Believers must be scripted that the cooling period after 1940 was due to pollution for two reasons. otherwise the theory of AGW caused by CO2 has a very inconvenient truth.
Here are the reasons the Mann-Hansen-Gore team scripted response on the 1940-1970 cool period is that it is caused by pollution
we fixed that pollution, fixed that cooling. Look! We can fix stuff.
obviously now we can fix CO2, fix that dangerous accelerated temperature riseYour citing the presence of major pollution today doesn't help a theory that we fixed major global cooling for a thirty year period by eliminating pollution.

No, Mann-Hansen-Gore had nothing to do with the research into particle pollution that causes cooling. It's a real phenomenon, I have experienced an extreme example myself. It's also the reason why Australia's average rainfall is constant, because it is the reason there is more rainfall in the NorthWest of Australia.

Mann-Hansen-Gore stretched the fact that particle pollution causes cooling out until it was said to cause a 30 year period of global cooling that overwhelmed the global warming that was happening at the same time.
Then they had an excuse why 1940-1970 did not fit their model.
Just like they tried to do away with

and just like their wish to show 1998 as warmer than the 1930s.All relating to showing "Unprecedented Man Made Global Warming" since the 1980s. Well, yes it was unprecedented, and yes it was man made. By them.
Here is the actual temperature data. The smooth line is a curve fit with pretty good correlation. The prediction is that temperatures will cool off in the coming decade.
No reason for alarm.

As far as I can tell, hansen moved from a less accurate system to one that is more accurate. McIntyre was wrong in either case. Please note there is a difference between accuracy and precision. What McIntyre is saying is science is just as accountable as any business when submitting data for public consumption. The law requires NASA/NOAA et al to abide by such standards of accountability. Hansen has been playing games and breaking the law. That may not sit well with you, but is the truth.
Would you please correct the incorrect information on your webpage. This request is made pursuant to the Data Quality Act.
Yours truly,
Stephen McIntyre
Let's see. McIntyre continually trawls through Hansen's data, looking for errors. He's a hero. Hansens moves to a more accurate data set, he's a fraud. He can't win, because if he stayed with the old one, he'd be criticised for that too.

Crocodile tears for Dr. Hansen.
As for the comment on troposphere warming, it sounds like you’re rewriting AGW hypothesis which says the troposphere should warm at a faster rate than the surface. Since this is not the case, that hypothesis is rejected. No Unique, if you bothered to look at the satellite data, there is no trend in the troposphere, hence the ‘new and improved’ global warming from Met O (Hadley).
You don't have to ask me, the IPCC has already worked it out. Read the report.

Perhaps the next subject should be how the Australian citizens get back all the money they gave to supposedly fix the "greenhouse gas emissions problem", after it is scientifically proven to not be a problem.
Shouldn't all those billions be given back?
We're headed over the top of the curve on this chart, temperatures are stabilizing. If the chart is right, then temperatures will head down.
Safekeeper, the people in Norway should get back the $466 per person that they were forced to cough up for the 2007 startup of higher utility bills that was supposedly to "reduce greenhouse gas emissions". Don't you want the money back?

THE Liberal Party has allegedly told its federal and state members to decline invitations to events starring former US vice-president Al Gore.
Since his failed presidential run in 2000, Gore has been an advocate for reducing carbon emissions and tackling climate change, reaching a wide audience through his Oscar-winning documentary, An Inconvenient Truth.
Invitations to the events run by public relations heavy Max Markson were issued to Liberals from the Prime Minister down. Only one accepted, then promptly cancelled.
"There is absolutely an official boycott in place," said Markson, a noted ALP fund-raiser.
"It is a national and state boycott. We had one NSW Liberal MP (respond) and he had to ring back and apologise and say he wasn't allowed to come. In the end the only Liberal Party representative at any event will be former PM Malcolm Fraser, who is turning up in Melbourne on Friday."
Liberal state director Julian Sheezel denied the party had told candidates to stay away.
"There is no credibility in that assertion at all," he said.

No Unique, there isn't a perfect curve leading onto the Mauna Loa. If you'd bother to research the many tens of thousands of CO2 measurements prior to and after Mauna Loa, you'd know the "perfect trend" is bunk. You would also know about the "missing sink".

Here is another chart from the compilation. An excel spreadsheet is downloadable with all the data, by the way.
Interesting that warmers ignore all the studies of atmospheric CO2 concentration except the two - ice cores and Mauni Lao - that supposedly support their hypothesis of CO2 being the primary driving agent for climate.
You would think, then, warmers could show a simple correlation between atmospheric CO2 and temperature - using some group of years for temperature and their preferred, cherry picked CO2 data.
I'm still waiting for that.
Thought that maybe the problem was in the data set, that more data would hep. So I got these and contributed them. In the meantime, given the apparent weakness of the CO2 hypothesis, it seems reasonable for me to stay on the skeptical side.;)

A note about the data. Please note that the ice core data provides only one measurement (one ice core???) at the beginning, middle and end of the bell shaped curve centered around 1942.
One measurement trumps hundreds, including those done by two Nobel prize winners?

For which reason the Mauna Loa curve and ice core measurements are shown, also, on the graph.
The chemical measurements as stated, had a max error of 3%.
Cherry picking a bit there are you?
The CO2 measuring jumps all over the place, until we start measuring it at Mauna Loa. Then all of a sudden, it doesn't jump all over the place.

Hundreds of seperate measurements by different people at different times using different equipment at different places under different conditions. One of the attractions of Mauna Lao is that it provides a "well mixed" consistent reading. The dove-tail from ice core to Mauna Loa shows the match up and consistency between the two.

No Unique, there isn't a perfect curve leading onto the Mauna Loa. If you'd bother to research the many tens of thousands of CO2 measurements prior to and after Mauna Loa, you'd know the "perfect trend" is bunk. You would also know about the "missing sink".
Aside from that, viewing the chart below, notice the pattern existing from the Mauna Loa measurements? What does it say? Even a wild guess?

This is a perfect example of cherry picking and data dredging.
Yet with your cherry picked dredges you cannot show that simple correlation between CO2 and temperature?
Not even with my giving you your choice of a subset of the years? 1850 - present, 1950 - present, 1980 - present?
Not even with my providing additional sources - over 135 actual data sets with 90,000 results - which I am also not objecting to your cherry picking and data dredging from?
I do not know what else is humanly possible to do, to help AGW Warmers produce a solid, credible and scientific foundation for the manmade CO2 drives climate change hypothesis.
You can not say I did not try to help.
This is not good for the credibility of the AGW hypothesis that CO2 is the major driver of climate. What can be done to salvage this theory?

A Congressional Briefing about forecasts of global warming given by Scott Armstrong on Thursday, Sept 13 is available on YouTube (http://tinyurl.com/yw8unx) The briefing was based on the Green & Armstrong paper "Global Warming: Scientific Forecasts or Forecasts by Scientists?" (http://forecastingprinciples.com/Public_Policy/WarmAudit31.pdf)The global warming paper is the first of what we hope will be many forecasting audits of public policy issues to be presented on the new Special Interest Group page at http://publicpolicyforecasting.com (https://webmail.wharton.upenn.edu/exchweb/bin/redir.asp?URL=http://publicpolicyforecasting.com/). (17 September, 2007)

and here is the full text of the paper "Global Warming: Scientific Forecasts or Forecasts by Scientists?". (http://forecastingprinciples.com/Public_Policy/WarmAudit31.pdf)
Some conclusions.
"We have been unable to find a scientific forecast to support global warming."
"Climate models use models to express their judgements.
The "Seer Sucker" theory proposed 1978 applies to global warming. "No matter how much evidence exists that seers do not exist, seers will find suckers". Tetlock (2005) found support for this theory with an evaluation of 82,000 forecasts over 20 years.

1. A challenge for AGW believers to cite a scientific atmospheric study that provided empirical evidence of the hypothesized greenhouse effects of CO2 in the atmosphere.
2. This is a link to a summary of Singer's theory (http://www.ncpa.org/pub/st/st279/st279.pdf) of the 1,500 year climate cycle, excerpted from his book. Debunk Singer's core theory, of the 1,500 year climate cycle.
3. Can a AGW believer show correlation or causation, or any relationship, between global temperature and global atmospheric CO2 levels?

Perhaps this will help. Here is a summary of 135 separate published studies of CO2 concentration in the atmosphere prior to Keeling's work.
Is there some period(s) of years that you can point to and show a mathematical relationship between CO2 and temperature?
Beck's study (http://www.biokurs.de/treibhaus/180CO2_supp.htm) goes back to the year 1800 and is the summary of 135 separate published studies and over 90,000 separate tests on atmospheric CO2 concentration with a precision of better than 3%.
Beck's paper really hasn't got much weight on this subject. The worst part of it in my opinion is how he takes every data point and draws a curve through every single one.
Other than that there's a stack of reasons why the reconstruction must be wrong.
He doesn't mention that site bias (not measuring precision) is what prevented accurate measurements back then. That's precisely why Callendar set up the Mauna Loa monitoring station so remotely - to avoid the contamination issues that plagued co2 measurements elsewhere.
Measurements taken in and around cities are subject to large variations in surface co2 that can be carried by the wind. co2 concentration can differ by location by as much as 100ppm. It's just not reliable.
Another good reason for Beck's reconstruction not being correct is that the record since Mauna Loa came online has shown co2 rising steady and smooth with less than 3ppm change from year to year, yet we are expected to believe that before the 60s co2 was jumping about year to year like crazy? As if it knew to start behaving once we started measuring it properly? In one case Beck's reconstruction has it jumping 80ppm and then falling again within a few years.
That raises another reason to doubt Beck's reconstruction. Current understanding of the carbon cycle can't explain how such rapid swings of that magnitude in atmospheric co2 could be possible.
The fact that the ice core records disagree is just the icing on the cake of reasons to believe the reconstruction is not correct.

No Unique, there isn't a perfect curve leading onto the Mauna Loa. If you'd bother to research the many tens of thousands of CO2 measurements prior to and after Mauna Loa, you'd know the "perfect trend" is bunk. You would also know about the "missing sink".
Aside from that, viewing the chart below, notice the pattern existing from the Mauna Loa measurements? What does it say? Even a wild guess?

It shows that the rise in co2 each year has accelerated over time as human emissions of co2 have accelerated over time, and it also shows the natural variation on top of this long term trend.

The causation was determined long ago. Here is a paper from 1956

Radiation-convection models of the atmosphere are based on empirical data, and those show co2 is significant component of the greenhouse effect, and that increasing co2 causes warming.

It is quite interesting, isn't it?
There is no question that the Mauna Loa does very precise measurements, however the chemical tests were said to be accurate to within 3%. 3% is fine for this work.
Now is there a substantial reason to throw out all, or part of the data?
If so, on what basis? Can you point to scientific studies that go through these 135 studies and invalidate them? I think not. That really is the quesiton, whether these studies have been refuted in the peer reviewed literature.
You bring up the fact that many of the tests may have been done near cities and may have been affected by the "co2 plume". Of course that was well understood, and please note, many were not so affected.

Yes, the surface is the source of co2 into the atmsosphere and as a result there is a lot of contamination going at the surface which is carried about by the wind. Very few areas at the surface represent the co2 concentration of the atmosphere as a whole because of this contamination.
This paper documents the existance of this contamination

How about that one? No gentlemen's wagers, money escrowed at the start.
I take from that the clear message that I'm not dealing with a gentleman.
You ask me to bet on "pretty shortly" and zero Arctic sea-ice. That won't happen until Greenland's northern coast stops calving icebergs, which will take some considerable time. (Unless things really go pear-shaped, of course.) I don't make bets where there's so much wriggle-room for the bookmaker.

I do not know what else is humanly possible to do, to help AGW Warmers produce a solid, credible and scientific foundation for the manmade CO2 drives climate change hypothesis.
You can not say I did not try to help.
This is not good for the credibility of the AGW hypothesis that CO2 is the major driver of climate. What can be done to salvage this theory?

Depending on what SC24 does, it may very well be as warm as today, maybe even slightly warmer. However, if SC24 is weak as some predict, it will be cooler and continue downward from there. By all accounts SC25 will be much weaker. SC24 is the grey area. There is a 4-15 year lag response.

Radiation-convection models of the atmosphere are based on empirical data, and those show co2 is significant component of the greenhouse effect, and that increasing co2 causes warming.
Plass is not the answer. Here was a guy working with first generation computing equipment in the middle of the Cold War. Effects of radiation were of interest at that time, his work fell into that general category. He followed the work of Callender and elaborated it into something of a theory that CO2 changes drove all climate changes, entire ice ages and the like.
Plass was essentially an early theorist of CO2 causes global warming. Lab measurements tell us what we know about the CO2 molecule today.
Where are actual experiments in the layers of the atmosphere that are supposedly affected by CO2? That show the green house effect of CO2 in the troposphere and stratosphere, and which therefore prove what exactly climate sensitivity is?
Published experiments, data and methods, that are repeatable? Actual atmospheric experiments with real air molecules, at real altitudes, as the sun comes up and the layer warms?
That doesn't seem an unreasonable question, does it?

Original data, that is flawed for the reason Oponol already stated, the CO2 is not mixed in well, which would explain the wild fluctuations seen in the data. The smooth curve observed at Mauna Lou is confirmed by two independent sources, the ice core, and Cape Grim. Neither of these sources have CO2 levels fluctuating so randomly.

It's not a matter of liking spaghetti graphs or not. It's a matter of are they reasonable or not. The chaotic behaviour of temparature is to be expected, the mixed level of CO2 not. The mix of CO2 at ground level in inhabited areas, yes.

Can I throw something else into the mix here?

I read here (on this forum) that the relationship and effect is one which has been understood for a long time.
I also read here that the threat of global warming comes from the potential further large increase in temperature that will be caused by future increases in CO2.
I am also aware of James Hansen who is a climate modeller and his views that temperature increases will acceleate (tipping points he refers to).
Then I came across this:
http://www.sciencemag.org/cgi/content/abstract/173/3992/138
and this statement in particular:
although the addition of carbon dioxide in the atmosphere does increase the surface temperature, the rate of temperature increase diminishes with increasing carbon dioxide in the atmosphere
My bold.
These were result from a climate model at the Institute for Space Studies, Goddard Space Flight Center. Wouldn't that be James Hansen's model?
So there is my dilemna. I can't see how all three of the statements above can be correct.
Either we haven't understood this for a long time, or the effect of the next increase in CO2 will be much less that that experienced to date.

That fact has been known from the start, and is well understood. It's not the issue, the main problem is the "enhanced" effect, from feedback mechanisms. It actually took a bit of work to convince scientists that CO2 was an issue, since the logarithmic response was well known.
1) Increasing CO2 will increase warming, either way, even if it is not as strong. Don't forget, we are talking about a doubling of the amount of CO2 with time, so even if the effect is reduced from the direct CO2 contribution, we are adding a lot of CO2 to the atmosphere.
2) There are feedback effects. These include change of albedo, as ice melts so that darker areas of the earth are revealed that absorb, rather than reflect, radiation.
3) Measured responses to CO2. Albedo is changing, temperature is rising.

Either we haven't understood this for a long time, or the effect of the next increase in CO2 will be much less that that experienced to date.
We haven't understood it for a long time, and numerous articles and studies indicate that a doubling of CO2 may yield a temperature increase of 0.5-1.1 degrees, not the 2.5-6.5 C that the IPCC indicates.
So there is a big argument over how much of an effect this is - is it a critical problem, requiring everybody to lower greenhouse gas output? Or is it a relatively insignificant problem? To put that into a perspective, suppose the increasing industrialization, technology transfers and rapidly increasing wealth in many parts of the world have a net effect by 2050 of raising global average temperature 0.5 - 1.0 C.
Most people wouldn't care. If it was 6.5 C, that is a tremendous difference.
So it is a giant lie when people say "the science is settled". There is a lot of misinformation, and there are a lot of people with agendas confusing the scientific issues.
Then there are issues with positive and negative feedbacks, and with these crazy "tipping point" ideas that Alarmists use. Hansen has moved into that arena. Every time the IPCC issues a report, their forecasts are less catastrophic, and Hansen gets more so.
I wouldn't bother reading the IPCC stuff, by the way. Maybe the summary for policymakers just to get a flavor of what they are telling governments should go do.

Getting back to the 'CO2 impact is negligible due to water vapor' canard ... A new study has been published by DOE / Livermore Natl Labs reaffirming:
I dunno, that article seems to be an elaborate example of "begging the question."
"When you heat the planet, you increase the ability of the atmosphere to hold moisture," said Benjamin Santer, lead author from Lawrence Livermore National Laboratory's Program for Climate Modeling and Intercomparison. "The atmosphere's water vapor content has increased by about 0.41 kilograms per square meter (kg/m²) per decade since 1988, and natural variability in climate just can't explain this moisture change. The most plausible explanation is that it's due to the human-caused increase in greenhouse gases."
We know that the air is warmer, and we know that warmer air holds more water, so unless there is some other link between greenhouse gases and air moisture then this statement makes no sense. We expect to find more moisture in the atmosphere because the air is warmer, this is true regardless of how the air got to be warmer.
More water vapor -- which is itself a greenhouse gas -- amplifies the warming effect of increased atmospheric levels of carbon dioxide. This is what scientists call a "positive feedback."
If this is true, if there is no other mechanism in the system to moderate or reverse this "positive feedback", then why isn't our climate like Venus due to a runaway greenhouse effect from the last warming period from 1500 years ago?
This isn't the first time the Earth has been this warm. If the warming causes the ice caps to melt, releases trapped CO2 in the permafrost, releases methane trapped under the sea, and all these countless other effects that feed this loop, then life should have ended many times over.
That I've never seen an adequate answer to this question is one of the primary reasons I'm skeptical of global warming theories.
Basically, "fingerprinting" involves searching for a computer model-predicted pattern of climate change (the "fingerprint") in observed climate records. Fingerprint techniques allow researchers to examine a change in some property of the climate system and make rigorous statistical tests of the different possible explanations for that change.
Okay, so what would have been useful information that this reporter chose to leave out is information that describes how this "fingerprint" is arrived at and exactly what it is that excludes other theories.

Please review the methodologies precisely.
What is causing the CO2 fluctuations in the Mauna Loa record?
When it comes to the El Nino/La Nina variation one possible explanation springs to mind. During a La Nina (and to a lesser extent during a La Nada) deep cold water upwells along the eastern coast of Latin America, bringing a wealth of dissolved nutrients. This nourishes phytoplankton which absorb CO2 from the ocean (which in turn absorbs it from the atmosphere). The vast biomass that results is evidenced by the wealth of fish in the region. Not all of it is eaten before it dies, of course, so some of the absorbed carbon sinks to be sequestered in sediments. That's a "carbon sink" for you.
During an El Nino, warm water flows east across the Pacific and slows down (perhaps turns off) the upwelling. Phytolankton die back and less CO2 is absorbed and sequestered. This is evidenced by the dearth of fish at such times.
Another point : the upwelling cold water can absorb more CO2 than warm surface water, firstly because cold water can hold more CO2, and secondly because the deep water is pretty old - centuries at least - and so hasn't been exposed to the high atmospheric CO2-load that's been around more recently.
That's off the top of my head. I'm sure the science is right, but I don't have numbers to run.
I've nothing on the intriguing volcano effect, apart from a recent paper suggesting that volcanoes leave a longer-lasting signal in oceans than they do in the atmosphere. (Where I came across it I can't recall.) This suggests a relatively strong cooling of oceans by volcanoes, thus dissolving more CO2. That's pretty rough, though. I hope somebody has something better.
At least this bar-chart puts the "eruptions emit more CO2 than humans do in a decade" meme to sleep.
Does it imply a long CO2 life cycle?

http://forums.randi.org/imagehosting/thum_1032346f1c6357bb97.jpg (http://forums.randi.org/vbimghost.php?do=displayimg&imgid=8431)Given that every year saw an increase in CO2 whatever the conditions, it certainly doesn't imply a short one. Perhaps medium - a 30 year half-life seems reasonable. We could perhaps narrow it down from the rising trend-line, but ballpark terms are good enough I'd have thought.
Do chemical laws apply to AGW such as Henry's Law Constant?
AGW is entirely consistent with all branches of science. And with observations made over the last few decades.

Quite. As I understand it, the feedback is logarithmic, not linear, so each unit increase has a smaller effect. This leads us to the mathematical concept of a limit.

Getting back to the 'CO2 impact is negligible due to water vapor' canard ... A new study has been published by DOE / Livermore Natl Labs reaffirming:
Two comments after reading the article.
1. It may well be that the reporter didn't do too good a job - that's not unusual - but I didn't get clearly what was proven and how from the writeup. Basically, my response after reading it was not "ah HAA" but "Huh?"
One thing is very clear, though, this is more computer modeling, not actual atmospheric experiments.
2. I've quoted and mentioned that Wentz 2007 seemed like an important article. Wentz showed that atmospheric water increase for a given temperature rise was almost 3x that shown in IPCC models, obviously invalidating those models. Also appears that the feedback effect nets out at negative (reasonable) vs. positive (unreasonable).
Brief conclusion: A lot is going on with the water and cloud cycle that we don't understand (we already knew that) and people are seriously trying to figure it out (a good thing) and they are making some progress.
Is the DOE/Livermore study related to one of the several challenges made to AGW believers? That wasn't clear to me.

They used the modelling to explain the measurements. I don't know what sort of experiment you think will satisfy you, given there is only one planet, and we don't have any spare ones handy to work with. We can create a virtual planet with models, however. Models are used throughout science and engineering, with great success.

Wentz does not invalidate the models. The models were known from day one to be deficient, and they are constantly being improved. They predicted an increase in water vapour content, and that has been measured. According to Wentz, the amount that falls as rain is larger than anticipated, but rain is also a cycle, so you can have both, more rain, and more water content.

There's only one atmospheric experiment going on at the moment.
You'll surely have noticed that there's a lot of observation in there.
"
Using 22 different computer models of the climate system and measurements from the satellite-based Special Sensor Microwave Imager (SSM/I), atmospheric scientists from LLNL and eight other international research centers have shown that the recent increase in moisture content over the bulk of the world's oceans is not due to solar forcing or gradual recovery from the 1991 eruption of Mount Pinatubo. The primary driver of this 'atmospheric moistening' is the increase in carbon dioxide caused by the burning of fossil fuels."
That's a lot of people signing-up to a career-breaker, don't you think? They seem to be pretty convinced. You may not understand why, but I'm sure they do. As do I.
2. I've quoted and mentioned that Wentz 2007 seemed like an important article. Wentz showed that atmospheric water increase for a given temperature rise was almost 3x that shown in IPCC models, obviously invalidating those models.
IPCC models? I thought the IPCC collated research and model results, rather than run models themselves. Are you sure this guy wasn't referring to the 22 models mentioned above? You may have read it as "IPCC models", but I doubt that's what was said.
If this guy's right it only invalidates the models insofar as they will underestimate the equilbrium temperature, given that H2O is a greenhouse gas. No refuge there, I'm afraid.
Also appears that the feedback effect nets out at negative (reasonable) ...
(comforting)
... vs. positive (unreasonable).
(alarming)
Is the article peppered with anti-fnords that I can't see? (OK, that is obscure.) How exactly does this appear from the article? (For which thank you, varwoche; just keep loading and passing on up for the cock-and-fire stuff :))
Brief conclusion: A lot is going on with the water and cloud cycle that we don't understand ...
There's a lot going on in the banking world that we don't yet understand. There's also a lot that we do understand. Given those two facts, the credit market has seized-up horribly. Caution is the watchword, as it always has been when this sort of thing has happened before. Of course, when it comes to AGW there isn't the same level of experience to go on.
... (we already knew that) and people are seriously trying to figure it out (a good thing) and they are making some progress.
Meanwhile there are record downpours from the Midlands through Africa, India and China, other regions are suffering droughts, and cyclonic activity is remorselessly increasing. Whatever the precise interplay of mechanisms may be, the observed outcome is not good. Which surely suggests caution even in the political world.
Is the DOE/Livermore study ...
More accurately, that would be "atmospheric scientists from LLNL and eight other international research centers". One blessing of being "international" is to be beyond the dread clutches of Al Gore.
... related to one of the several challenges made to AGW believers? That wasn't clear to me.

According to Wentz, the amount that falls as rain is larger than anticipated, but rain is also a cycle, so you can have both, more rain, and more water content.
The H2O component of the atmosphere is always tiny compared to the H2O throughput. Of course, as humans it's the throughput - rain and dessication - that we care about. We call it "weather". When it comes to climate, it's that tiny component that makes a difference. And the climate dictates the rate of throughput.
It's a point worth making, I think. It's why, in general, wet places will become wetter and dry places will become drier.
There are, of course, larger movements. The same pole-ward shift of rainbands seems to be bringing floods to central Africa while it brings drought to Australia.
Time to quit Australia and move to the greening Sahara. Heck, isn't that how humanity has coped so adequately with climate change in the past? It's no big deal. People can always move :rolleyes:.

Well, I certainly have not made my mind up. That's why I've repeatedly asked the Believers to provide simple, direct scientific evidence. And why these questions arose -
Unanswered Questions and Challenges
1. A challenge for AGW believers to cite a scientific atmospheric study that provided empirical evidence of the hypothesized greenhouse effects of CO2 in the atmosphere.
It's not one paper, that would be impossible, since the subject is so complex. Ref IPCC reports.
2. This is a link to a summary of Singer's theory (http://www.ncpa.org/pub/st/st279/st279.pdf) of the 1,500 year climate cycle, excerpted from his book. Debunk Singer's core theory, of the 1,500 year climate cycle.
There are so many woo papers, it would be impossible to debunk them all using the scientific process, without extra funding. Hang on, you just said that was all that motivated them. Give them more funding.
3. Can a AGW believer show correlation or causation, or any relationship, between global temperature and global atmospheric CO2 levels?
Pretty simple. Shouldn't be that hard. No good answers so far....

Perhaps this discussion by Christy will help as a introduction to why cloud and precipitation systems operate as a negative, not a positive feedback.

Precipitation Systems: Nature's Air Conditioner? (http://www.weatherquestions.com/Roy-Spencer-on-global-warming.htm)
It is well known that precipitation is an important process in the atmosphere. Besides being necessary for life on Earth, all of the rain and snow that falls to the ground represents excess heat that has been removed from the Earth's surface during the evaporation of water. That heat is deposited in the middle and upper tropopshere when the water vapor condenses into clouds, some of then produce precipitation.
I believe it can be demonstrated that precipitation systems ultimately control most of the Earth's natural greenhouse effect. Most of the atmosphere (the lower 80%, called the troposphere) is continuously being recycled through precipitation systems (see Fig. 7), on a time scale of weeks. Winds in the troposphere's 'boundary layer' pick up water vapor that has been evaporated from the surface, and then transport this vapor to precipitation systems, where an equal amount of vapor (on average) is removed as rain or snow.
Partly because precipitation systems cover only several percent of the Earth's surface at any given time, even most climate researchers do not appreciate the controlling influence these systems have on the climate system. All of the humid air flowing into precipitation systems in the lower troposphere ends up flowing out of those same systems, mostly in the middle and upper troposphere. (The only exception is thunderstorm downdrafts, which you have likely experienced before). That air flowing out has moisture (water vapor and cloud) amounts that are controlled by precipitation processes within the systems. This constitutes the direct effect that precipitation systems have on the Earth's natural greenhouse effect.

Is there a relation between Hurricane Intensity and Global Warming in Australia? (http://www.worldclimatereport.com/index.php/2007/08/29/hurricanes-down-under/#more-261)

A team of scientists from institutions in Australia and New Zealand figured a way to do it, and here is the trick. The water that condenses in the clouds of tropical cyclones is slightly different from the water that forms in regular tropical clouds. Due to the enormous amount of water in a tropical cyclone and the height at which water condenses, the water is depleted in a particular isotope of oxygen (called the "oxygen 18 isotope" and denoted as "δ18O"). The Nott et al. team explain "An isotope gradient occurs across the cyclone with the eye wall region experiencing lowest levels of δ18O and low levels also occur within the zones of uplifted air around the cyclone known as spiral bands." It is likely that the most intense tropical cyclones will have "cloud tops at greater altitude around the eye and in spiral bands. The longevity of the system and hence the amount of rain that has occurred prior to the system crossing the coast also plays a role in the extent of isotope depletion." So if we had a water sample from each event, we could examine the δ18O level and have an index of the severity of the storm – finding the water samples sounds like a problem.
They estimate tropical cyclone intensity from AD 1226 to AD 2003, and global warmers will not be happy.
Nott et al. writes "it is clear that the period between AD 1600 to 1800 had many more intense or hazardous cyclones impacting the site than the post AD 1800 period. Seven events that were more intense/hazardous than the 1911 event occurred during this 200 yr period. Indeed the cyclone registering the lowest isotope difference value, hence the most intense or hazardous, of the entire record occurred here during this time."

The atmosphere's water vapor content has increased by about 0.41 kilograms per square meter (kg/m²) per decade since 1988, and natural variability in climate just can't explain this moisture change.
I'd be amazed if they could explain it. Last I knew our atmosphere has three dimensions. (kg/m²) is two dimensional. I would find it astonishing if they could find any three dimensional content contained within a two dimensional area. Is there some alternate universe I haven't heard about?

It appears they are referring to per m2 of the earth's surface, which is quite valid. If they were referring to per m3, the figures would make no sense at all.

Precipitation Systems: Nature's Air Conditioner? (http://www.weatherquestions.com/Roy-Spencer-on-global-warming.htm)
It is well known that precipitation is an important process in the atmosphere. Besides being necessary for life on Earth, all of the rain and snow that falls to the ground represents excess heat that has been removed from the Earth's surface during the evaporation of water. That heat is deposited in the middle and upper tropopshere when the water vapor condenses into clouds, some of then produce precipitation.

With all due respect, Safekeeper, typing "Words" like "Positive feedback" is not descriptive of the process. Go back and read about Positive and negative feedback. Here is just one fundamental issue from our friend Wikipedia.
Does it apply to climate? Can you draw the feedback loops and assign values to them? How do you prove that a given feedback is positive or negative?
Nyquist stability criterion (http://en.wikipedia.org/wiki/Stability_criterion)
The Nyquist stability criterion, named for Harry Nyquist (http://en.wikipedia.org/wiki/Harry_Nyquist), provides a simple test for stability (http://en.wikipedia.org/wiki/Stability) of a closed-loop (http://en.wikipedia.org/wiki/Closed-loop) control system (http://en.wikipedia.org/wiki/Control_system) by examining the open-loop system's Nyquist plot (http://en.wikipedia.org/wiki/Nyquist_plot). Stability of the closed-loop control system may be determined directly by computing the poles (http://en.wikipedia.org/wiki/Pole_%28complex_analysis%29) of the closed-loop transfer function (http://en.wikipedia.org/wiki/Transfer_function). In contrast, the Nyquist stability criterion allows stability to be determined without computing the closed-loop poles (http://en.wikipedia.org/w/index.php?title=Closed-loop_poles&action=edit).

That heat is deposited in the middle and upper tropopshere when the water vapor condenses into clouds, some of then produce precipitation.
I believe it can be demonstrated that precipitation systems ultimately control most of the Earth's natural greenhouse effect. Most of the atmosphere (the lower 80%, called the troposphere) is continuously being recycled through precipitation systems (see Fig. 7), on a time scale of weeks. Winds in the troposphere's 'boundary layer' pick up water vapor that has been evaporated from the surface, and then transport this vapor to precipitation systems, where an equal amount of vapor (on average) is removed as rain or snow.
Partly because precipitation systems cover only several percent of the Earth's surface at any given time, even most climate researchers do not appreciate the controlling influence these systems have on the climate system. All of the humid air flowing into precipitation systems in the lower troposphere ends up flowing out of those same systems, mostly in the middle and upper troposphere. (The only exception is thunderstorm downdrafts, which you have likely experienced before). That air flowing out has moisture (water vapor and cloud) amounts that are controlled by precipitation processes within the systems. This constitutes the direct effect that precipitation systems have on the Earth's natural greenhouse effect.

I'm not going to read all your links, but if I understand your point correctly you're just saying that increased water vapor in the air leads to more heat being radiated back into space because the water vapor carries it up to the troposphere?

Ahh, yes, I did miss that post. Sorry. Although I would probably add that there is easily the chance for many other things going on that contribute to the climate balancing. Then again, I was generally aiming my comment towards the other side of the argument as I feel that a lack of understanding of climate feedbacks and the climate system as a whole seems to be a very weak point in the AGW argument.

When a microphone feeds back, it doesn't keep on getting louder forever, it's limited by the power of the amplifier. When the climate has feedbacks, it's limited by the power coming from the sun, or the feedback mechanism itself runs out. Albedo changes when ice melts, causing the earth to absorb more radiation, rather than reflect it. When all the ice is gone, that's the end of that feedback mechanism. It's all also limited by the amount of radiation from the sun in the first place.

But the earth will change permanently, and it is a rapid change in geological terms. From a thermodynamic point of view, rapid change = chaos. Previous rapid changes have seen mass extinctions. We, collectively, will see massive changes needed in our infrastructure. The global wheat crop isn't doing too well, this year, for example.
We have seen the Asian economic meltdown come and go, and the rest of the world carried on, ditto 9/11, and other massive hits on the earths economic systems. This will affect all countries in the world, at the same time.
It will mean many species, such as polar bears being the most obvious ones, go extinct. Many other species will need to move to cooler climates, or adapt. Adaptation takes time, and the species won't have hat. Man now controls much of the land that blocks the way for species migration.

Look what's the most important topic for the Australian election this year.
http://www.theaustralian.news.com.au/story/0,25197,22461097-601,00.html
THE unprecedented crisis in the Murray-Darling Basin has propelled water to the top of the political agenda, with John Howard and Kevin Rudd battling to convince voters they can alleviate the devastating effects of Australia's prolonged drought.
The Prime Minister yesterday promised more drought relief for farmers, with Peter Costello outlining a controversial solution for urban water shortages -- a desalination plant for every capital city.
And Kevin Rudd used his trip to Walgett in northwest NSW to promote a $60 million strategy to help farmers prepare for the effects of climate change.
Under the Howard rescue plan -- to be considered by cabinet next week -- irrigators and communities suffering through record-breaking drought in the Murray-Darling Basin will receive extra support, probably in a two-phase package. It will include changes to exceptional circumstances drought assistance to make it easier for farmers -- particularly those who rely on irrigation -- to access immediate financial relief.
The package is also likely to include longer-term measures targeted at communities along the Murray that have received little or no water allocations this season and are watching their permanent plantings and crops die.
Farmers predict that if all the permanent plantings in the basin die it will cost up to $4 billion to replace them and the lost income could total $8 billion.
There are so many complaints about the cost of preventing climate change, but little appreciation of the cost of coping with it. The figures mentioned are just the dollars to deal with the farmers. A far bigger cost will be the increased cost of food.

Thank you for the analogy.
When the climate has feedbacks, it's limited by the power coming from the sun, or the feedback mechanism itself runs out.
Which doesn't make sense. There is no practical limit to the output of the Sun, and there is no indication of when any of the feedback mechanisms listed would "run out".
Albedo changes when ice melts, causing the earth to absorb more radiation, rather than reflect it. When all the ice is gone, that's the end of that feedback mechanism.
Except it wouldn't be the end. The ice would still be gone, and taken at face value the theory would suggest that the lack of ice would prevent the cycle from ever swinging back to cooler temperatures.
Yet the Earth has been warmer in the past than it is right now, and if that were true then we would never have our current situation. So there must be some mechanism that would not just end the feedback mechanism, but reverse its effects.
Either that or the alarmists are mistaken.
It's all also limited by the amount of radiation from the sun in the first place.
Which is a lot, and is not a practical limit for the sake of this discussion.

What is causing the CO2 fluctuations in the Mauna Loa record? Does it imply a long CO2 life cycle?
There is natural variation from year to year as many natural sources and sinks are sensitive to temperature. The rising co2 trend due to human activity is on top of this variation. Not sure whether you are refering to residence time of an average co2 molecule, or amount of time it would take for the atmosphere to return to pre-industrial co2 levels.
Do chemical laws apply to AGW such as Henry's Law Constant?
Yes and also warmer oceans absorb less co2.

Where are actual experiments in the layers of the atmosphere that are supposedly affected by CO2? That show the green house effect of CO2 in the troposphere and stratosphere, and which therefore prove what exactly climate sensitivity is?
I think you have to give an example of an experiment that would be necessary or would even work. I don't buy the idea that you can just sit a sensor somewhere in the atmosphere and determine what the warming effect would be of doubling co2.

A limited amount of energy reaches the earth from the sun.
If all ice on earth were to melt, there would no longer be a feedback loop caused by decreasing albedo.
The ice would still be gone, and taken at face value the theory would suggest that the lack of ice would prevent the cycle from ever swinging back to cooler temperatures. First off, what theory?
Second, there are factors that effect temperature other than albedo, obviously.
Yet the Earth has been warmer in the past than it is right now, and if that were true then we would never have our current situation. Unclear what you mean here.
So there must be some mechanism that would not just end the feedback mechanism, but reverse its effects. If you are trying to say that there are factors that effect temperature other than albedo and man made CO2, you are correct and I'm pretty sure you will find no disagreement on such basic facts.
You seem to be implying that a theory has been put forth that AGW will cause the earth to be permanently hot. If such a theory exists, I'm unaware of it.

That should be enough to model the absorption and emission of radiation in the atmosphere
HITRAN, in which serious errors were found and corrected just recently.
(Were studies done using HITRAN prior to 2005 corrected and restated with the new data? Not that I am aware of).
In the apparent lack of adequate atmospheric experiments, here is one format.
Keep in mind, as DR has pointed out, that atmospheric CO2 concentration varies considerably - in one location, over the course of a year - downwind of a major urban environment - in a year with El Nino or without.
Moreover, numerous environments hold low or negligible quantities of water vapor.
Therefore, it seems possible to look directly at various concentrations of CO2 in the air and what their effects are, instead of taking refuge in highly questionable computer modeling.
A balloon (or series of them) is launched with instrumentation to measure IR spectral emission, temperature, CO2 concentration and the like. The supposed effects of CO2 enhancing the "greenhouse effect" are at higher tropospheric altitudes.
On top of the balloon is placed a circular "fence", made perhaps of simple bubble plastic with aluminized mylar on the outer side.
Air above the balloon is now largely sheltered from IR radiation from the earth. Air on sides and below the balloon is affected by IR radiation. The hypothesis to be tested might be "there is no measurable difference in temperature of the samples of air protected from Earth's IR as compared to samples exposed to Earth's IR.
Of course "temperature" would imply that the CO2 absorbed IR and it became kinetic energy and was imparted to other air molecules in the vicinity. There is more arm waving in theory of CO2 greenhouse effects than that, some has to do with "re emission" by CO2 of photons.
Make no mistake about it, the physics gets very complex and the modeling by computers is unable to handle adequately exactly what CO2 does in the air, with other gases around it.

Add to the list of things which influence atmospheric CO2 - the full moon. Man's supposed contribution is about 1.2 ppm per year, so every full moon is a variation equal to about 2 years of man's supposed contribution. Variation due to yearly climate - looks like about 9 ppm.
It should be pretty easy to design an experiment that picks a time and place of testing, such that the range of CO2 concentrations in the atmosphere equal to 10 years of man's supposed contributions, and evaluate the hypothesized CO2 effect based on that.

Atmospheric CO2 concentration varies considerably - in one location, over the course of a year - downwind of a major urban environment - in a year with El Nino or without.
Moreover, numerous environments hold low or negligible quantities of water vapor.
Therefore, it seems possible to look directly at various concentrations of CO2 in the air and what their effects are, instead of taking refuge in highly questionable computer modeling.
A balloon (or series of them) is launched with instrumentation to measure IR spectral emission, temperature, CO2 concentration and the like. The supposed effects of CO2 enhancing the "greenhouse effect" are at higher tropospheric altitudes.
On top of the balloon is placed a circular "fence", made perhaps of simple bubble plastic with aluminized mylar on the outer side.
Air above the balloon is now largely sheltered from IR radiation from the earth. Air on sides and below the balloon is affected by IR radiation. The hypothesis to be tested might be "there is no measurable difference in temperature of the samples of air protected from Earth's IR as compared to samples exposed to Earth's IR.
Of course "temperature" would imply that the CO2 absorbed IR and it became kinetic energy and was imparted to other air molecules in the vicinity. There is more arm waving in theory of CO2 greenhouse effects than that, some has to do with "re emission" by CO2 of photons.
Make no mistake about it, the physics gets very complex and the modeling by computers is unable to handle adequately exactly what CO2 does in the air, with other gases around it.

Ahh, yes, I did miss that post. Sorry. Although I would probably add that there is easily the chance for many other things going on that contribute to the climate balancing. Then again, I was generally aiming my comment towards the other side of the argument as I feel that a lack of understanding of climate feedbacks and the climate system as a whole seems to be a very weak point in the AGW argument.
There's a lack of precision in some feedbacks, but no great lack of understanding. Water-vapour is a positive feedback. Clouds may be a negative one, but if so observation reveals that its effect is small. Permafrost is a positive feedback, as is albedo.
It's difficult to be precise about the numbers involved since science has never before had the opportunity to observe climate change of this magnitude. That's the atmospheric experiment that's going on now : jack up CO2-load and see what happens. Observations taken during the experiment will teach us more about the various interactions and their scale.
Science can make some inferences about the overall scale of feedbacks from glacial/inter-glacial phase-shifts. Picking apart the different contributions is problematic, though. Direct observations made during the current warming will avoid that problem. We have satellites to observe cloud-cover, albedo, and the tree-line. The behaviour of melting premafrost can be studied on the ground. Surface and sub-surface sensors can monitor the oceans. We'll be pretty expert on the whole subject in a few more decades.

The criticism, as far as I can make it out, is that the models aren't coming up with the detail. They never have been expected to, and probably won't, since what appears to be the demand is that they model the micro climates around the world, which are subject to chaotic behaviour. They do appear to track the average global temperature pretty well, though, which is what they are claimed to be able to do, given the scenarios that have to be taken into account. Given that rise in temperature, the feebacks that are predicted are happening, and observable.

Not only that, but no unexpected feedbacks have appeared. The rate of, say, permafrost melt is unexpectedly high, but we always knew it would be a positive feedback - permafrost sequesters a lot of carbon. It probably makes a significant contribution during glaciatl/inter-glacial phase-shifts. Working out how much is bit of a nightmare, of course, given that the permafrost-zone migrates on the surface of a sphere.
I'll make a point here that may not be universally appreciated : a positive feedback amplifies any change, warming or cooling. If the "natural cooling phase" that some predict for the near future does occur, the positive feedbacks will soon make it apparent.

I've provided some of my own (on the previous page). Care to comment on it, or provide a little analysis of your own?
"What about this, then?" does not constitute an argument. "Well, what about it?" does , on the other hand, constitute a response. So ... what about it?
The bar-chart reveals that CO2-load is increasing. The rate varies year-on-year - which is why decadal figures are more illuminating than annual - but it carries on inexorably upwards. To my mind, that's a lot more relevant than annual (let alone monthly) variations in the rate.

Add to the list of things which influence atmospheric CO2 - the full moon.
Is there any discernible trend in this lunatic influence, do you know? The Moon to me, in all its phases, is one of those constants that puts all this surface-skim stuff into perspective.
Man's supposed contribution is about 1.2 ppm per year, so every full moon is a variation equal to about 2 years of man's supposed contribution. Variation due to yearly climate - looks like about 9 ppm.
And yet, according to the David Rodale bar-chart, when you work out the accounts at the end of the year the bottom-line keeps coming out positive. So all that intra-annual variation really means nothing.
It should be pretty easy to design an experiment that picks a time and place of testing, such that the range of CO2 concentrations in the atmosphere equal to 10 years of man's supposed contributions, and evaluate the hypothesized CO2 effect based on that.
While isolating said place from the rest of the world's climate. Not really practicable, is it?
You might well find somewhere with a wildly fluctuating CO2-load, but what will that tell you? Squat, that's what. Greenhouse warming doesn't happen overnight.

Atmospheric CO2 concentration varies considerably - in one location, over the course of a year - downwind of a major urban environment - in a year with El Nino or without.
If you total all the areas downwind (?) of urban enviroments, it still comes to a tiny fraction of the Eastern Pacific influenced by El Nino/La Nina. Just to get some sense of scale.
Moreover, numerous environments hold low or negligible quantities of water vapor.
None of them over the oceans, which constitute about 70% of the surface. Of the rest, the dessicated area is a small minority. There's a desert band from the Sahara to the Gobi but it's well outweighed by the wetlands to North and South.
Therefore, it seems possible to look directly at various concentrations of CO2 in the air and what their effects are, instead of taking refuge in highly questionable computer modeling.

Which is why Hansen says he is worried. When the climate changes, it often seems to flip from one state to another, due to the feedback mechanisms. We have been fortunate to live in a time when negative feedback mechanisms have kept the climate relatively stable.

You are confusing the time for co2 equilibrium to be reached with how long and where the effect is seen, if there is any effect. For troposphere, consider 20,000 feet. It takes an hour or so for a cumulonimbus to develop and reach 20,000 feet. That or less is obviously how long co2 on the ground spreads. As I recall from somewhere, the speed of reaching equilibrium concentration in gas partial pressure should be the speed of sound in the medium (might have that wrong).
But that has no relation to how and when there is a greenhouse effect. There is one or is not one as the case may be, at 20,000 feet at the instant the sun rises above the horizon, and begins the process of thermal warming of the planet. You can take it from there to see the daily cycle, and also the "global warming" cycle as it applies to winter and summer.
The actual effect of "global warming" should be in the rate of change of tropospheric temperatures, right? How rapidly they heat up in response to the Earth's IR, and how rapidly their heat content decays.

1. We need to talk about heat capacity and heat energy, not temperature
You are ignoring the change that is happening. In terms of degrees K, it's quite small, but that small change is enough to change the climate and ecosystems drastically. That is, and always has been, the point.
2. Clouds are the real thermostat, having far more temperature regulating power than CO2
Ditto. So far clouds haven't stopped the warming, either.
3. There have been over 40 scientific studies that prove the atmospheric CO2 lifetime to be 5-6 years, not the "hundreds of years" that the IPCC alleges.
It's the change that is significant. Mauna Loa and Cape Grimes both show, it's steadily increasing. The isotope measurements confirm it's us adding the extra CO2. It's not going away, it's accumulating.
Overall the AGW concept is primarily a radiative energy model, while the actual planet is mostly a convective energy system.
It's the radiation that is trapping the extra heat, jacking up the temperature of the whole system, that is, it is a 'forcing'.
Now AGW True Believers deny over 135 peer reviewed studies of the amount of CO2 in the atmosphere, and also, over 40 scientific studies of the lifetime of CO2 in the atmosphere.
No, it's about why is it increasing, the change that increased amount is causing, and the lifetime of that increase.

Dude, clouds/water vapour trap heat, and to a much greater extent than CO2.
The effect of clouds is two-fold : on the one hand they reflect light from the Sun back into space (some of it even back into the Sun, where it has no significant effect), on the other they radiate infra-red down to the surface. Where it has some effect.
Water-vapour is a very different matter. It doesn't relect light from above, but it does absorb infra-red from below. That said, clouds are full of water-vapour, and the air below them is generally close to saturation. So the water-vapour effect probably dominates on a cloudy night.
It has long been a contrarian argument that clouds might be a negative feedback to climate change, but experience has demonstrated otherwise. It was always very speculative.
Water-vapour has long been recognised as a positive feedback to any climate forcing.

Most of the atmosphere is transparent, so it doesn't reflect anything, long-wave infra-red from the surface at any time or short-wave sunlight during the day. Long wave radiation does not reflect as readily as short-wave, so reflection of infra-red by clouds is tiny if it exists at all.
Apart from which, even in cloudless conditions there's still an infra-red glow from the atmosphere. It's not reflection. Re-emission, as per greenhouse theory, remains a very credible candidate.

The rate of increase is varying, not the CO2-levels. Look at your bar-chart again. Every year different, but every year an increase.

Of course there isn't, since there are other influences. Such as the effects of El Nino/La Nina/Itsa Nada on carbon sinks.
b)the 200 year life cycle is not observed
Hardly likely on such a short-term chart, and what's this 200-year life cycle? Do you mean the 100-year half-life?

Of course they do. Who's ever said different?
Further, does CO2 have the omnipotent power to control ENSO and volcanoes?
Is it not more likely that El Nino/La Nina and ENSO influence carbon sinks? I commented on that a page or two back, in a direct response that you seem to have ignored, unless I've missed something. Which is always possible.
How can CO2 levels drop during volcanic eruptions which emit high levels of CO2?
How can you claim that volcanoes emit significant amounts of CO2 when the evidence shows that they reduce the rate of increase? I'm still at a loss to explain the mechanism involved, but there it is in the data. Volcanoes do not emit significant amounts of CO2.

Thank you, Varwoche, but I'm not trying to partake in an argument, I'm just asking some questions about a subject I don't understand as well as I would like. If you don't understand the questions I'm asking or have no answers, then please leave it for someone who does.
There is not one single question-mark in the post that varwoche was responding to. No questions, just statements. Such as "there's no practical limit to the output of the Sun". Which there is. More to the point, the Sun's output is observable and observed.

The question was why we can detect infra red in the night sky ...
Do you think there is a chance that any of the massive amount of heat that is being radiated from the Earth on the night side, is being reflected back by the clouds and the atmosphere ?
Why would you care what I think, I'm not a scientist, and this is a complex area of research. I would seriously suggest you read the 4AR, if you question any of the claims made by the IPCC, then move on from there. Otherwise this is all just a waste of time.

Scientists? Well then.
Instead of reading the IPCC, the summary documents of which were written by non scientists and reviewed, changed and approved by governments before printing, one would want the scientists independent assessment.
Well... at least if you thought a 16 year old kid might get it wrong...
(hint: of course she got it right, why else would I have linked...:rolleyes:)This page provides information on the Independent Summary for Policymakers (http://www.uoguelph.ca/%7Ermckitri/research/ISPM.pdf) (ISPM) of the Fourth IPCC Assessment Report (AR4), recently published by the Fraser Institute (http://www.fraserinstitute.ca/). The ISPM is not a critique of or a response to the IPCC Report. It is a detailed summary, written on the premise that a great deal of good, balanced science is presented in the IPCC report and it should be widely disseminated and carefully read. The ISPM includes some 300 direct citations to the IPCC report and provides detailed chapter locations so that readers can look up the IPCC sections for themselves.
In producing this Summary we have worked independently of the IPCC, using the Second Order Draft of the IPCC report, as circulated after revisions were made in response to the first expert review period in the winter and spring of 2006. Section references will be checked against the final IPCC version, to be released in May 2007. If, in preparing the final draft of the Fourth Assessment Report, the IPCC substantially rewrites the Assessment text, such that the key summary materials presented herein need to be re-worded, we will do so and publish an Appendix to that effect.

Most of it is from water-vapour. Not in the ten or twenty metres above ground, obviously. That's just silly. But there's no question that water-vapour is the most influential greenhouse gas. There's no shortage of it at any temperature that doesn't freeze over the oceans.
If water-vapour were the only greenhouse gas, the oceans would be frozen all the way through. Earth's climate would be no different from the Moon's.
It's not wet atmosphere that makes the Earth warm, it's a warm Earth that makes the atmosphere wet. CO2 is what makes for a warm Earth. Water-vapour is just a positive feedback.

Take this.
This is a huge problem for the IPCC and greenhouse gas theorists. Not only do they have enormous numbers of calculations to make for each cubic meter of atmosphere, but those calculations change every few seconds depending on temperature, humidity, elevation, lattitude, local geography, clouds, wind, time of day, season, and etc. They try to use super computers to make these calculations, but even the best computers are not powerful enough, which is why computer climate models are still only “an approximation of reality” (Veiser 2000).
She seems to think that the computers have to model the actions of every molecule reacting with every photon, which is nonsense, of course. They don't model anything like every cubic metre.
Another problem that has been suggested with the whole radiative-heat transfer theory proposed by the IPCC is because as altitude increases, density decreases, thus leading to fewer and fewer collisions. There are fewer molecules in a unit of space above than below. I would agree that CO2 molecules would suffer fewer collisions at higher altitudes and have a chance to relax and emit their photons in all directions, 50% in an upward direction and 50% in a downward direction. But the photons headed upward are going to travel farther than the photons traveling downward because of the lower density above. Further, as the photons travel downward and are absorbed by CO2 molecules, they are again subjected to collisions. This makes me wonder how a photon can make it back to the surace of the earth and reheat the surface.
That's evidence. All you have to do is wonder how something can be true, decide it's not, and that's it.
The whole essay is full of rubbish like this.

nzclimatescience? "commonsense about climate change" give me a break. Science is not about common sense. If it was, no one would have thought of quantum mechanics. It is more and more about understanding highly complex systems. A bunch of earnest nutters and contrarians, with little actual expertise in what is actually being researched, doing just what the deniers all want, finding any answer but CO2, which is the point. It's the sun, no it's a natural cycle, no it's not actually changing, measurements are wrong, it's anything but CO2. Vincent Gray is past it, he has no idea what current research is nor how to understand it, Bellamy is a botanist, Carter is a simple contrarian in the mold of Lindzen, who is outside his field of competence.
Hoo boy AUP is getting desperate.
Perhaps I should put this in a sig:
"Science is not about common sense - AUP"
Clearly rattled by inconvenient truths, you resort to smear, innuendo and plain old-fashioned lying.
YOU are the simple contrarian. YOU are the denier.
CO2 has never caused warming as seen by every ice core record which shows carbon dioxide rise to be a delayed response. Why? Because YOU don't understand quantum physics. If you did, you'd know that the mean temperature of the atmosphere cannot rise by simply changing the partial pressure of a trace gas.
But you don't know that, because in AUP-world, ignorance is a part of view.

The night-sky glows in the infra-red. What more do you need? That radiation - heat - is coming from the sky straight back here. Absent any alternative explanation - as usual - this confirms greenhouse theory.
You mean, in the absence of an atmosphere, the night side of a planet falls straight to absolute zero?
Greenhouse theory predicts things which are not observed in the real atmosphere. But rather than deal with them, claim that everything change in the atmosphere, warm or cold, is predicted by greenhouse theory when it doesn't.

No. The night sky, above the atmosphere radiates at about 4 degrees Kelvin,
and yes that has an impact on the plantary surface temperature.
The first few posts on this topic were made by a strident and very incorrect "scneibster' who incorrectly assumed that the temperature calculation was a simple one based on black body radiation. That is (it should be clear) nonsense. Albedo and the spectral characteristics of the atmosphere are rcitical to any argument. The relationships are not simple and each 'effect' has other side effects which may either increase or decrease the supposed warming trend.
The problem is highly complex - I hope we see this now. Let me make an analogy. We have another highly complex system in biology, but in the case of biology, unlike environmental sciences, we can create experiments which are substantially comparable to the cases of interest. Yet there are differences. I was just reading through the data sheet on a new medication.
There was some evidence of a tertogenic effect of this med at high doses in a particular breed of rat, but not in other test animals. There was a possible carcinogenic effect at very high long term doses in some animals, but not others. So what exactly are the implications for normal use in humans ? It's very difficult to say anything definitive. The big pharma company that developed this medication makes very cautious statements and careful disclosures regarding the extrapolated impact of this medication on humans.
Now in contrast we have environmental scientists who, like astronomers and cosmologists, are unable to implement useful experiments. They must be satisfied with observation of existing environments. So exactly how many planetary atmospheric systems have environmentalists studied ? How often were their models demonstrated to accurately predict surface temperature ? Given the single local planet as their primary object of study - just how good is the quality of long-term temperature records and records of atmospheric gaseous content, of volcanic activity ? Obviously the answer is that this observations that inform this area of study have severe limitations. Despite this the recent claims of accuracy and consensus by all, are remarkably lacking in caution and are not at all circumspect.
If environmental scientists were as subject to law suit for damages as drug companies they would, I think, be making more careful statements about what data is currently suggesting, rather than jumping on the fear-mongering bandwagon.
No science is not about common sense and it is also not about concensus. I don't really care if an argument is proposed by an illustrious committee nor a 16 yo girl. As in any rational discussion , we should evaluate the arguments and not the proponents.
We should all be concerned that human activity has *apparently* caused a significant increase in atmospheric CO2. No one can argue that pollution via CO2, NO, ozone depleting chemicals and ground-water polluting chemicals is a net good. Also the amount of phosphorus and nitrogen that human activity makes available as runoff chemicals has a large net positive impact on the amount of plant growth - which is also generally viewed as a negative.
So whether one believes in the catastrophic global warming hypothesis or more simply in the clearly evidenced idea that current human activity is having a major impact wrt conventional pollution - what can practically be done about it ?
What force would compel less developed countries from burning fossil fuels even if more advanced countries avoid these ? What force will cause a roughly 1/3rd population decrease that would be necessary to avoid creating atmospherically fixed nitrogen for farming ? (it's estimated that 30-40% of all the nitrogen in the average human comes from a chemical plant).
Let's get past the dubious climate hypothesis. What can be done about it is a very intractable problem.

Pretty good comments and I agree with your approach. However you include co2 as a pollutant.
It would be nice to actually establish if man-made CO2 in the atmosphere is a "bad" or not. How could that be done?

Corbyn has a knowledge of the climate, but he hides it from everyone. That completely breaks the scientific model. The howls from McIntyre about about Jones are piercing, because they can't produce the data years after a paper was written and it has been long lost, but Corbyn won't even produce a reason why claims what he does, he just arbitrarily states results with no more reason than it's got something to do with the sun.

But on www.climateaudit.org (http://www.climateaudit.org), plenipotentiary suggests a solution in line with the general concepts of anthropogenic causation.
Posted on 09/18/2007 12:28:41 AM PDT by plenipotentiary (http://www.freerepublic.com/%7Eplenipotentiary)Q I still haven’t had explained to me how the seasonal variations in CO2 concentration create the seasons.
A Well, first of all you have to forget all that stuff about the spinning Earth being tilted at an angle of twenty-something degrees to the ecliptic, and cooling during its Northern winters, warming during its summers. Forget about the Sun. Or better still, think of the Earth as being flat.
Think instead about CO2 in the atmosphere. During summer, when plant photosynthesis is maximum, plants absorb CO2 from the atmosphere, and reduce its levels, and thus reduce global warming, resulting in a subsequent cold winter. During winter, when plant photosynthesis is at a minimum, CO2 levels tend to rise, resulting in global warming - and the subsequent warm summer.
See. Quite easy to explain.
You’ll probably want to know about anthropogenic seasonal variation too. That is, how humans manage to create the seasons. And this happens because, during winter, humans tend to light fires to keep warm, and these fires generate CO2, which causes global warming, and results in warm summers. During these warm summers, humans stop burning fires, and the excess CO2 is absorbed by plants, reducing atmospheric CO2 concentrations, and bringing global cooling, and the subsequent winter.
The result, as I’m sure you’ll see, is that the seasonal cycle of spring-summer-autumn-winter is entirely created by human activity, and if humans would simply stop burning fires in winter, this seasonal variation would vanish, and terrestrial surface temperatures would remain more or less constant.
Convinced? I’m sure you are. If you want to save the world from the endless cycle of the destruction of the creation, all you have to do is to not turn on your heating system when temperatures fall 10 or 20 degrees C below zero. It would also help if you stayed outside, and didn’t wear any clothes, or ate anything. You know by now that it makes no sense to do stupid things like that, right?

If I understand correctly, what you're saying is that because the air is thinner in the upper atmosphere, that more heat is radiated away from the planet because heat that radiates down towards the planet is more likely to encounter more molecules in the denser air and thus be re-directed upwards again?
Also, if IR is detected in the night sky, it's evidence that heat is being radiated away from the planet?

But on www.climateaudit.org (http://www.climateaudit.org), plenipotentiary suggests a solution in line with the general concepts of anthropogenic causation.
Posted on 09/18/2007 12:28:41 AM PDT by plenipotentiary (http://www.freerepublic.com/%7Eplenipotentiary)Q I still haven’t had explained to me how the seasonal variations in CO2 concentration create the seasons.
A Well, first of all you have to forget all that stuff about the spinning Earth being tilted at an angle of twenty-something degrees to the ecliptic, and cooling during its Northern winters, warming during its summers. Forget about the Sun. Or better still, think of the Earth as being flat.
Think instead about CO2 in the atmosphere. During summer, when plant photosynthesis is maximum, plants absorb CO2 from the atmosphere, and reduce its levels, and thus reduce global warming, resulting in a subsequent cold winter. During winter, when plant photosynthesis is at a minimum, CO2 levels tend to rise, resulting in global warming - and the subsequent warm summer.
See. Quite easy to explain.
You’ll probably want to know about anthropogenic seasonal variation too. That is, how humans manage to create the seasons. And this happens because, during winter, humans tend to light fires to keep warm, and these fires generate CO2, which causes global warming, and results in warm summers. During these warm summers, humans stop burning fires, and the excess CO2 is absorbed by plants, reducing atmospheric CO2 concentrations, and bringing global cooling, and the subsequent winter.
The result, as I’m sure you’ll see, is that the seasonal cycle of spring-summer-autumn-winter is entirely created by human activity, and if humans would simply stop burning fires in winter, this seasonal variation would vanish, and terrestrial surface temperatures would remain more or less constant.
Convinced? I’m sure you are. If you want to save the world from the endless cycle of the destruction of the creation, all you have to do is to not turn on your heating system when temperatures fall 10 or 20 degrees C below zero. It would also help if you stayed outside, and didn’t wear any clothes, or ate anything. You know by now that it makes no sense to do stupid things like that, right?
And you posted this, why?
I mean, what is the point of plentipotiary's vapid post.
Does his not making any sense support your not making any sense?

You need to learn about the variation of temperature with altitude. Do not assume that at higher elevations the temperature is colder, it is not so. And you don't make sense talking about a single molecules temperature, pressure or expansion.
you are just not making sense
I'm quite aware of temperature gradients, lapse rates, humidity vs. altitude, etc. What does not make sense?

If I understand correctly, what you're saying is that because the air is thinner in the upper atmosphere, that more heat is radiated away from the planet because heat that radiates down towards the planet is more likely to encounter more molecules in the denser air and thus be re-directed upwards again?
Also, if IR is detected in the night sky, it's evidence that heat is being radiated away from the planet?
Please correct me if I'm wrong.
More or less. If you read IR with a meter pointed up, you are reading the cumulative IR from all of the atmosphere above your position. That in turn is comprised of emissions from water vapor, CO2, and the supposed "all important" additional bit of CO2 from man made sources.
This has been discussed in great detail hundreds of places and rapidly gets quite technical. Here are some comments from DocMartyn in a discussion at www.climateaudit.org (http://www.climateaudit.org) which explore ways to actual prove or disprove the theory we are discussing -
DocMartyn says:
February 2nd, 2007 at 7:48 pm...if CO2 has the ability to reflect IR back to the ground level then it can easily be measure.
The temperature profile of the south pole has been studied since the 50’s. I looked at the RATE at which the pole cools in the winter. One would expect GHG to slow the rate of cooling, if CO2 were a powerful GHG. Alas, the pole appears to be cooling more rapidly now than it did 40 years ago, although the changes are quite small. I suspect that this would also be the case in dusk til dawn temperature change in sand deserts. The Arizona crater would be a good site. in this one we could raise the CO2 to 800ppm with ease and have a look at the change in the day and night time absolute temperatures.
Finally, finally, they never do actual expirements. I have never seen anyone shine a pulsing signal(tuneable)-laser into space through the atmosphere and measure the amount of light absorbed and light reflected back to Earth. Using ground stations, aircraft and satallites it would be relitivly easy to workout what was happening to the light and where it was going. These people don’t do this sort of thing, either because they dont have a background in expirements or they are worried about the answers.
Which leads right back to....

What planet do these guys life on? He's a conspiracy theorist and all. CO2 is not a 'powerful' GHG. It just happens that if you increase the concentration, it will increase the temperature by a degree or so, by itself, and the feedback mechanisms will take care of the rest, as is being observed.
You don't need to shoot a laser into space, you just need to do it in a lab to observe the effect. I don't even think a laser would be the right frequency, it's long wavelength radiation, not short, that is doing the heat transfer.
Why is he afraid to just read up on the existing literature that explains all this? Is he worried about the answer?

It includes the one-third extra CO2 and the extra water-vapour that results from the warming effect that one-third extra CO2. Water-vapour is a feedback. Since water-vapour is the dominant factor in the greenhouse effect, that's the all-important addition, don't you think? (Forget clouds and stuff, let's postulate clear skies here.)

I can't help thinking - and saying - it becomes a comforting hum to you at that point.

Events are really putting the onus on disproof, don't you think? The situation is evolving just as predicted by AGW decades ago, with increasing precision as time has passed. Ice-retreat has been a surprise, but in rate, not sign. As with all inevitable retreats, the timetable is the focus of discussion while events dictate.
DocMartyn says:
February 2nd, 2007 at 7:48 pm...if CO2 has the ability to reflect IR back to the ground level then it can easily be measure.
At which point he demonstrates his pig-ignorance. CO2 does not reflect infra-red. AGW is not based on that erroneous concept in any manner or form. No molecule reflects anything. Reflection is an electromagnetic phaenomenon that manifests in vastly larger systems. Clouds, for instance, or a mirror.
All that follows is just as worthless because it's derived - rather amateurishly, in my opinion - from nonsense.

Scientists? Well then.
Instead of reading the IPCC, the summary documents of which were written by non scientists and reviewed, changed and approved by governments before printing, one would want the scientists independent assessment.
Well... at least if you thought a 16 year old kid might get it wrong...
(hint: of course she got it right, why else would I have linked...:rolleyes:)This page provides information on the Independent Summary for Policymakers (http://www.uoguelph.ca/%7Ermckitri/research/ISPM.pdf) (ISPM) of the Fourth IPCC Assessment Report (AR4), recently published by the Fraser Institute (http://www.fraserinstitute.ca/). The ISPM is not a critique of or a response to the IPCC Report. It is a detailed summary, written on the premise that a great deal of good, balanced science is presented in the IPCC report and it should be widely disseminated and carefully read. The ISPM includes some 300 direct citations to the IPCC report and provides detailed chapter locations so that readers can look up the IPCC sections for themselves.
In producing this Summary we have worked independently of the IPCC, using the Second Order Draft of the IPCC report, as circulated after revisions were made in response to the first expert review period in the winter and spring of 2006. Section references will be checked against the final IPCC version, to be released in May 2007. If, in preparing the final draft of the Fourth Assessment Report, the IPCC substantially rewrites the Assessment text, such that the key summary materials presented herein need to be re-worded, we will do so and publish an Appendix to that effect.
It's starts off with a basic lie
The ISPM was prepared by experts who are fully qualified and experienced in their
fields, but who are not themselves IPCC chapter authors, nor are they authors of the
IPCC Summary for Policymakers.
Yet look at the retired scientists on the report? Kininmonth is a good example. He has no idea what the state of the science is, he has never worked in it.

That reply doesn't make any sense either, so I'll break down the post I said made no sense.
Hmmm.... let's see. A CO2 or water molecule gets excited by being hit, bangs around a bit more...that's gas expansion.
A single molecule cannot expand
So we're talking a gas working against gravity, the atmosphere moving up a bit.... where it is colder.
An increase in altitude does not necessarily indicate a decrease in temperature.
That uses up the kinetic energy of the gas heated by radiation from the earth doesn't it? Is some energy left over to re radiate downward? Is there a lot of it? How much?
A bit hard to move energy from a colder place to a hotter place, isn't it?
Ooops.
Again, confusing the properties of a single molecule with the properties of a large number of molecules, just like the 16 year old with her vapid football analogy. I don't get women and football analogies.
Also when CO2 absorbs the infared photon, the increase in energy goes to the stretching and vibrational modes of the molecule, not the velocity which corresponds to the temperature. Only when that molecule collides with another molecule can that vibrational energy be transferred into heat or the velocity of another molecule.
Looks like Kristine Byrnes, the high school student, does make sense.
So AUP, what do you say we go through her table of contents one chapter at a time? Might be lots of good rubbish there.

Since water-vapour is the dominant factor in the greenhouse effect, that's the all-important addition, don't you think? (Forget clouds and stuff, let's postulate clear skies here.)
It's all important only because CapelDodgy thinks its all important. Water vapour is a feedback because Capeldodgy is fixated by MAN-MADE carbon dioxide. The atmosphere has positive feedbacks because CapelDodgy says they do, not because they exist.
And no, we can't forget clouds and stuff because they are critical factors in a NEGATIVE FEEDBACK system which dominates the Earth's climate. We also can't forget the Sun, unless of course you're really determined.
But if there was warming die to an enhanced greenhouse effect, then there would be other observations which would be obvious, such as a large warming of the upper troposphere above the tropics - something that isn't observed.
We still haven't heard the Capeldodgy explanation for how increasing the partial pressure of a trace gas like carbon dioxide can cause warming because its never happened in the past, and it cannot happen according to quantum physics.
But then, since when has ignorance of physics ever stopped Capeldodgy before?

New York- Czech President Vaclav Klaus told journalists in New York today it would most help the debate on climate change if the current monopoly and one-sidedness were eliminated.
In his speech at the special U.N. summit on climate change in New York today Klaus said that despite the artificially created idea about a large extent of ongoing climate changes, the recent rise in global temperatures has been very small in historical comparison and its impact on man and his activities are basically negligible.
Klaus told journalists that the only chance was his proposal that the United Nations organise two parallel inter-governmental panels to discuss climate changes and publish two competing reports, because it was a political question.
"Let us look for a real solution," he said.
He said he would not take part in today's lunch at which former U.S. vice-president Albert Gore who holds the views on the global warming different from Klaus's would be present.
He said he agreed that it was correct to compare different views.
"However, this would require the side that behaves as if it has a monopoly on the truth showed the willingness for a dialogue and a public discussion. I am prepared for such a debate any minute," Klaus said.

Once again going back to this simple observation, why are CO2 levels varying with ENSO and volcano events?
Because both affect global temperature and that has a knock on effect on how much co2 is emitted/absorbed over a full year.
Does it suggest a)there is no lockstep consistent rise in CO2 caused by fossil fuels
Certainly not
b)the 200 year life cycle is not observed
Certainly not
How can CO2 levels drop during volcanic eruptions which emit high levels of CO2?
Volcanoes don't emit high levels of co2. co2 most likely drops because of the cooling of global temperatures in the years following a large volcanic erruption.
Note the correlation between temperature change and CO2 change in the following graph:
It is difficult to discern at first glance looking at the seemingly perfectly smooth upward trend normally shown, but the pattern is definitely there. What is actually driving CO2 levels?
Human emissions
Please explain where Segalstad is wrong:
http://folk.uio.no/tomvs/esef/esef0.htm
http://folk.uio.no/tomvs/esef/whatisco.ppt
Sorry don't have powerpoint, but he's confusing atmospheric lifetime of a single molecule (a few years) with residence time for co2 to fall back to previous levels (decades to centuries). The longer time period is due to the fact that as more co2 from the atmosphere is absorbed it becomes harder to absorb more. While co2 drop would start off fast, it would slow down. Much in the opposite way it has risen.

Overall the AGW concept is primarily a radiative energy model, while the actual planet is mostly a convective energy system.

Now AGW True Believers deny over 135 peer reviewed studies of the amount of CO2 in the atmosphere, and also, over 40 scientific studies of the lifetime of CO2 in the atmosphere.

Volcanoes don't emit high levels of co2. co2 most likely drops because of the cooling of global temperatures in the years following a large volcanic erruption.
More precisely, from the barchart presented by David Rodale it's the rate of increase in CO2 that drops, not CO2.
The cooling effect, especially on the oceans (thereby enabling them to dissolve more CO2), is my first guess too. I also wonder whether there's and "ocean-seeding" effect from ejected material - iron and potassium in particular. Speculation, of course, but informed speculation :).
I mentioned earlier (possibly on the Arctic Ice thread) that the fall-off in the rate of increase demonstrates that volcanoes do not emit significant amounts of CO2, but David Rodale seems to have missed that entire post.
If somebody would care to fund me, I'll happily hang out in the South Seas with a small fleet of research vessels waiting for an eruption. When one kicks off it'll take me next to no time to throw aside the dusky maidens, sober-up, and start the observations. Honest. I'm raring to go.

New York- Czech President Vaclav Klaus told journalists in New York today it would most help the debate on climate change if the current monopoly and one-sidedness were eliminated.
As a politician, Klaus no doubt finds a disinterested field of study, such as science, incomprehensible.

He's very ignorant, isn't he? And not a nice person - you should check out his wider political stance.
Klaus told journalists that the only chance was his proposal that the United Nations organise two parallel inter-governmental panels to discuss climate changes and publish two competing reports, because it was a political question.
See above. Klaus clearly can't distinguish between science (a search for truth) and politics (choosing a belief).
It would actually be interesting to watch him, and like-minded politicians, appoint their alternative IPCC. Would Crichton be in, I wonder? Would explicit rejection of the existing IPCC reports be a necessary qualification? Presumably members of the IPCC would be excluded. The cat-fight over precedence amongst those that do get in would be deeply amusing too.
Ain't gonna happen, though. Or it would have done already.
"Let us look for a real solution," he said.
From his statement he already knows there isn't an AGW problem, so the problem this solution applies to is presumably the progress - glacially slow though it is - towards action being taken. An anti-IPCC would stop that.
He said he would not take part in today's lunch at which former U.S. vice-president Albert Gore who holds the views on the global warming different from Klaus's would be present.
Gives you a flavour of the guy, doesn't it? Unless he just wasn't invited or has a prior engagement.
He said he agreed that it was correct to compare different views.
Well he would, wouldn't he?
"However, this would require the side that behaves as if it has a monopoly on the truth showed the willingness for a dialogue and a public discussion. I am prepared for such a debate any minute," Klaus said.
He's not prepared for a scientific debate, he's up for a rhetorical debate full of lawyers' tricks, like any standard politician. Or like Singer, as another example.
This is the Science Forum, not Politics. So I'll say no more about Klaus.

I was posting very specifically about a proposed experiment to measure the atmosphere's response to infra-red emissions from the surface.

When mhaze quotes someone who starts off with CO2 reflecting infra-red, I'm on it like a fly on a flesh-wound. That's my choice :).
It's not as if contrarians need to be convinced before the real world is allowed to go its own way. Which is just the way that we expected from a while back, having a good grasp of the science. Not exactly as we expected, because we never had an exact expectation. We had a general expectation, and lo, we were right and now we're starting to see the detail.
Not the detail of how things were twenty years ago, of course, who cares? (Lots of people, apparently.) The detail of the process. One thing that's very clear is that the process is faster than we generally expected twenty years ago.

Yes, that would be helpful.
I mean, that is what this whole thread is about, that is the theory about how CO2 as a greenhouse gas can cause an increase in temperature.
Your statements about what happens when a CO2 molecule absorbs a photon of infared light cleary show that you do not understand the process at hand.
Any statements by you that will clearly show that you understand the process would be helpful.
It is difficult to find peer reviewed literature on the internet that describes this process, as the science is not very new. Introductory college texts on Astonomy or Organic chemistry or spectroscopy would have the information.

I don't know how much raising the level of CO2 in the Arizona crater to 800 ppm would cost (although it might be as simple as lighting some fires), but if the laser in the sky would bring results, that doesn't seem so expensive.

See my post above. This accusation is based on conflating two seperate processes.
Convection, included, very poorly if you like.
As for CO2 and it's time in the atmosphere, when you the 200 year life cycle is observed are you referring to the time for CO2 to lapse back to "pre industrial levels"? In turn that implies that the "good level" of CO2 is the pre industrial level?
Trying to be sure I have your point of view right...

I don't know how much raising the level of CO2 in the Arizona crater to 800 ppm would cost (although it might be as simple as lighting some fires), but if the laser in the sky would bring results, that doesn't seem so expensive.
I might be wrong, but if there is anything testable about the issue then shouldn't it be tested?
Wonders never cease.
Taking a quick look at the Winslow crater, about 0.2 cu km in volume, looks like four K tons of co2 would double the concentration. That's without considering losses.
Even considering losses, it does not seem to be a big job to do it.

Convection is not hard to model.

That will take many thousands of years, if it happens at all. See the graph oponol has linked to.
In the short term CO2 can be taken up in biomass, but there's a limit to how much, since CO2 is not the only limiting factor in plant-growth. Water, space and nutrients are not in infinite supply.
The ocean's capacity to absorb CO2 reduces when it warms (as it is today), but it's still not saturated. Over-turning brings up cold deep water which has not yet been exposed to the high over-pressure of CO2 during the last century. Surface water, with its a high concentration of CO2, sinks, thus gradually sequextering the CO2. I say "gradually" because this overturning cycle takes place over thousands of years.
In turn that implies that the "good level" of CO2 is the pre industrial level?
It implies no such thing. There is no "good" or "evil" level of CO2. No value-judgments ares involved. This is just science.
With the fossil-CO2 that's already been added to the oceans and atmosphere a new equilibrium will be reached in a few centuries. That equilibrium will necessarily be higher than the pre-industrial equilibrium since there's a lot more CO2 in the system. A third more in the atmosphere, and a goodly amount in the oceans (I'm not sure what proportion, but significant enough for surface-water acidification to be a concern in itself).
Trying to be sure I have your point of view right...
I've described the science as best I can. Any questions?

Well, CP, you have presented the IPCC view. I'm just trying to get at what Oponal exactly meant. Since the view as you have presented it is that which is commonly presented, but when one examines the actual research, it does not seem clear at all.
You have presented assertions. They may or may not be correct. Consider: Why are we discussing this? Because DR referenced some 40 studies that show that turnover of CO2 in the air is a few years - say 5 years. Therefore, I noted that "now believers deny 135 studies of CO2 concentration, and 40 studies of CO2 turnover" or something to that effect.
Oponal indicates that's apples and oranges. Looks like the same issue to me, unless the discussion is the one I just asked regarding the time frame to get the atmospheric concentration back down to preindustrial levels.
Turnover of CO2 appears to take just a few years, not the hundreds you years you claim (and the IPCC, and oponal claims, but I am not sure of his context).
It would appear that the IPCC, you, and Oponal must reject the 40 studies of atmospheric turnover time for CO2, in order to assert "hundreds of years". I am not saying that I completely understand this issue, but I do understand it isn't completely understood.

Well, CP, you have presented the IPCC view.
What is it with you and the IPCC? The IPCC is a panel convened by governments under the auspices of the UN to report on the current state of science appertaining to climate change. It does not have a view, not does it dictate to the world of science.
What I wrote was about the science. Did you read any of it? If so, do you have a problem with any of it? Is there any point I should expand on?
I'm just trying to get at what Oponal exactly meant. Since the view as you have presented it is that which is commonly presented, but when one examines the actual research, it does not seem clear at all.
Yes, it does. You just need to be able to understand the research.
You have presented assertions. They may or may not be correct.
I can assure you they are correct. Pick one and tell me it isn't.
Consider: Why are we discussing this? Because DR referenced some 40 studies that show that turnover of CO2 in the air is a few years - say 5 years.
Turnover rate is not the same as retention rate. (I think that's been pointed out before.)
Therefore, I noted that "now believers deny 135 studies of CO2 concentration, and 40 studies of CO2 turnover" or something to that effect.
Knowing the difference between retention rate and turnover rate does not amount to denying studies of turnover rate (which some of those studies might actually allude to, for all I know). Where concentration comes into it I don't know.
Oponal indicates that's apples and oranges. Looks like the same issue to me ...
No surprises there.
... unless the discussion is the one I just asked regarding the time frame to get the atmospheric concentration back down to preindustrial levels.
Actually, your stuff was one long non sequitur.
Turnover of CO2 appears to take just a few years, not the hundreds you years you claim (and the IPCC, and oponal claims, but I am not sure of his context).
I was referring to retention rate. Not turnover rate.
It would appear ...
It clearly does so appear to you ...
... that the IPCC ...
Again with the IPCC :confused:.
... you, and Oponal must reject the 40 studies of atmospheric turnover time for CO2, in order to assert "hundreds of years". I am not saying that I completely understand this issue, but I do understand it isn't completely understood.
OK.
Turnover rate first. Turnover rate refers to the average time a molecule of CO2 spends in the atmosphere after it enters it. This is, apparently, on the order of five years. CO2 leaves the atmosphere when it enters plants or is dissolved in the ocean. It returns to the atmosphere when plants decay or are eaten and digested (much the same process), or when it evaporates from the ocean. There it stays for, on average, something like five years then goes through the cycle again.
Retention rate next. Retention rate refers to how long a mass of CO2 introduced over a short period into the atmosphere continues to have an influence on the CO2-load. This is on the order of a century or two.
Think of the system as a job-market. People move between jobs : turnover rate is analogous to the average time they spend unemployed. Increase the the labour-pool by, say, 10% without creating more jobs : the retention rate is how long it takes for the unemployment rate to return to its previous level.
Over the long-term CO2 will be sequestered from the atmosphere in the form of limestone. That's a slow process. In the meantime we're going to have to get used to it being around.

Correction: 75 kilo tons.
This is going to look frickin' amazing if you get the lighting right.
Obviously, the only way this could be done is by dumping two or three thousand refrigerated truck-loads of dry ice into the crater over a very short period - a few hours, maybe. It could be done - just build enough refrigerated storage capacity nearby and hire in a few hundred trucks - but the effect will be really spooky as all the moisture in the air above and around the crater condenses. Like I say, with the right lighting it would be a real show. You could finance the whole thing by selling tickets and transmission rights.
Apart from that, what's the point again?

You are no more a part of this debate than the football-fan who paints his naked oversized belly his team colours and belches ridicule at his opponents between gulps of stadium beer is a member of the team he cheers.

To return to the Avery-Singer saviour cycle of 1500 plus or minus 500 years, this seems to be founded on D-O events, which involve a rapid warming around Greenland. They've been detected in the record of the last glaciation, and seem to have a peridicity of about 1500 years. They are associated with glacial periods, not inter-glacials, and they represent local warming, not global warming. In fact, D-O events are associated with a cooling in the Southern Hemisphere. The current working theory (no pun intended) is that they involve a cyclic variation in the thermohaline circulation that transfers heat between the North Atlantic and the Southern Oceans.
On that basis, D-O events represent a redistribution of heat-energy within the system, not global warming. They bear no relation to what's occurring now.
Is there more to the Saviour Cycle than that?

AGWr's arguments are discussed in extnd in this paper:
A Layman's Guide to Man-Made Global Warming
http://www.climate-skeptic.com/2007/09/table-of-conten.html
The purpose of this paper is to provide a layman’s critique of the Anthropogenic Global Warming (AGW) theory, and in particular to challenge the fairly widespread notion that the science and projected consequences of AGW currently justify massive spending and government intervention into the world’s economies. This paper will show that despite good evidence that global temperatures are rising and that CO2 can act as a greenhouse gas and help to warm the Earth, we are a long way from attributing all or much of current warming to man-made CO2. We are even further away from being able to accurately project man’s impact on future climate, and it is a very debatable question whether interventions today to reduce CO2 emissions will substantially improve the world 50 or 100 years from now.
Despite the "layman" word, the paper shows a very good amount of reasons to be sceptical about AGW, as described in the IPCC 2007 report.
Worth the reading.

In the meantime, I'm talking to you.
Everything you have said regarding the CO2 cycle is your opinion only and does not change my point of view.
My opinion only? Is it only my opinion that CO2 is both dissolved in and evaporates from the oceans, and that one molecule can be dissolved at one time and evaporate later? Or that CO2 can be absorbed by photosynthesis and subsequently breathed out by browsing animals? Are there opinions otherwise?
But you are welcome to produce some references that lend credibility to your assertions.
Produce some that lend credibility to any other opinions. Those would be opinions that don't accept that CO2 can be absorbed by grass to make leaf and then be breathed out by browsing animals. Are you aware of any such opinions?
Regarding Singer and D/O cycles, you can follow the links I have provided after you requested something that could be accessed with a low speed modem - html version of Singer. You will find lots of interesting things that you may feel you can refute.
Given that you've found them already, why not present them? What's in there apart from the D-O events? Something must have convinced you.

The origin of the "80%" was your claim that reports of Arctic ice-extent were 50-80% inaccurate. Remember? You actually said something along the lines of "All these reports are 50-80% inaccurate" and then retreated into "predictions are 50-80% inaccurate", not having noticed the difference between prediction and report. Do you really want to revisit that?
I know you think your question is terribly clever, but it still doesn't absolve you of that earlier silliness. Nor is it clever.
Anyhoo, can you raise some of those opinions that are so different from mine? And anything substantial on the Singer-Avery cycle would be appreciated. Surely you can remember something other than the D-O events, given how impressed you seem to be by it.
If all Avery-Singer have is D-O events, I've already dealt with it. D-O events include a Southern Hemisphere cooling - measured by the same means, and by the same people - so they have nothing to say about global warming. This is global redistribution of heat-energy. I surely don't have to explain the difference.

No it wouldn't be that simple, since then you would have all the other components of smoke to deal with. As CD poited out, you would need large amounts of dry ice, a big laser and a lot of measuring equipment... all stuck in a hole in Arizona. Then you would need no wind, so that you have no particles in the air, some test runs, so that you can figure where to place the equipment, and a couple of planes to check the amount of infrared escaping the hole.
Of course, this means that the scientists involved had to take a few years from their own research - and their lives- to form a consortium, write a proposal, and start actually implementing it. This to basically show what we already know.
Or you could start emmiting huge amounts of CO2 into the atmosphere, and wait till the concentration is high enough for the sky to glow in infrared...

Bulk CO2 is 0.15 - 0.30 USD per kg, so it would appear that the initial amount mentioned, 75 KG, would simply be a matter of ordering some bulk (liquid CO2) tanker trucks over. $100K USD would buy say at $ 0.25 per KG 400,000 KG, which should do nicely.
Note that my calculation of 75kg was to double the entire concentration of CO2 - and that there is really no need to do that, increasing the concentration by one third or one half would likely do fine.
The experiment would only show what we already know? Our knowledge should be at least as good as our proof of theories of man made causation of the ozone hole, right?
But the "scientific consensus" on anthropogenic ozone depletion may have been completely wrong Singer's 1989 opinion (http://www.sepp.org/key%20issues/ozone/advinozon.html) that banning CFCs was premature and scientifically wrong appears correct.Alfred Wegener Institute of Polar and Marine Research in Potsdam, Germany, did a double-take when he saw new data for the break-down rate of a crucial molecule, dichlorine peroxide (Cl2O2). The rate of photolysis (light-activated splitting) of this molecule reported by chemists at NASA’s Jet Propulsion Laboratory in Pasadena, California1, was extremely low in the wavelengths available in the stratosphere - almost an order of magnitude lower than the currently accepted rate.
“This must have far-reaching consequences,” Rex says. “If the measurements are correct we can basically no longer say we understand how ozone holes come into being (http://www.icecap.us/).” What effect the results have on projections of the speed or extent of ozone depletion remains unclear.
Our understanding of the ozone hole formation, twenty years after the Montreal protocol, is in shambles. Of course more studies are needed to verify these conclusions. Perhaps the ozone scare should have been suspect in the first place, since the theory was proposed by Lovelock in 1974.
Given gross errors in the consensus of science coupled with political action such as this, how can one say that the hypothesized meteor crater experiment, "would only prove what we already know?"

Thanks - since CD really, really does not want to answer this question. Some people are math - phobic.
But no to your answer, because they are two separate observations.
2005 - Ice was somewhere between 900 and 1100.
2006 - Ice was somewhere between 810 and 990
Ice could have increased by 90k or decreased by 290k. Or anywhere in between...
Which is right? The simple statement, "Ice decreased by 100k", or the statement qualified by the error bounds?
This illustrates a point you made earlier about Kristin Byrnes, and our discussing the effect of CO2 in the upper atmosphere either in (a) 16 year old grammer (b) "adult" grammer (c) limited technical language readable to most say, college educated people(d) several levels of actual technical vocabulary. What level is the best to explain or discuss something on?
My one course in college on quantum theory was so long ago as to enable me to truthfully say I have sort of a really vague idea about quantum theory.
Regarding the possible consequences of CO2 in the upper troposphere and lower stratosphere. With CO2 we are talking about "three body problems". The interaction of the molecules with the rest of the atmosphere are impossible to model with computers. It appears impossible to know the relative proportion of energy transferred from CO2 via re emitted photons, and the proportion transferred to surrounding molecules as kinetic energy. In turn this implies lab experiments on CO2 do not provide a valid factual basis for the behavior of CO2 in the upper atmosphere. Also note the 2nd law of thermodynamics, energy does not move from a cold area to a hot area.
