Sea ice status thread.

[BenBurch]

This is the thread to post actual data about sea ice conditions. Please debate AGW on some other thread. Data only here, PLEASE.

As of the readings of 4 September 2008;

Arctic sea ice extent is very close to last year's record loss and the gap between the two is closing.

Antarctic sea ice extent is slightly below average and much below that of last year.

I guess I will steal David's thunder, from his other post:

You are right, Antarctic sea ice extent is currently about 3-5% below last year.

The current images are much closer to last years, as the graph would show you. The average product is just that, an average for the month, and we started August much behind last year and caught up over the course of the month;

I see ice!

Here is a place where you can see sea ice!

That is a whole lot of ice. Darn convinience stores and the Ice Machine Conspiracy!

[Wangler]

Thats right! Thank heavens it's the Antarctic, and therefore meaningless.

[Dancing David]

It means alot to those what love it!

Please keep THIS thread at least on topic? I was hoping to make a place to put data, not clever comments or debate.

[bobdroege7]

another look to compare this year with last, almost a tie.

Anyone know what this might mean?

Nothing unusual then. Polar sea ice shrinks in summer and reappears in winter.

A longer melt season perhaps.

If it gets to January, the ice cap is gone.

Yes. The melt ends later, on average, every year.

[Wangler]

No, I meant in the whole AGW sense.

Does it mean that the melt season is longer each year? If so, any reasoned explanations why?

Or does it mean that the melt season is delayed more each year? If so, any reasoned explanations why?

Anybody ever thought about it?

Sorry Ben, I was trying to make some lightness before the usual descent into lies, misdirection and smearing. The Arti ice has shrunk quite a bit, beyond all known records. Despite the cigarette/asbestos industry style tactics that will be presented soon. Much of Antartic ice looks as though it may break free as well.

[Wangler]

Lookin (http://nsidc.org/arcticseaicenews/index.html)' pretty good compared to last year!

[mhaze]

no, it's BADDD! Really, it is! Just look at it! Doesn't it Worry You?

We're Doomed. Doomed, I tell ya . Doo

Not enough difference to spit at, actually. Last year was the worst ever. This year is the second worst, eclipsing 2005. Even in a steep decline, there are year-to-year variations that make the signal noisy. This is one of them.

[portlandatheist]

What I think is interesting is this winter there was MORE ice than there has been in quite some time (look at the winter 2008 peak http://arctic.atmos.uiuc.edu/cryosphere/IMAGES/global.daily.ice.area.withtrend.jpg ) but that was a short lived reprieve with this summers ice melt

[Dancing David]

The sea surface anamolies temperatures are interesting

[jimbob]

In what way Dancing David?

Linky please?

hello,

From Wanglers link:

It is the fourth down, I think.

[Wangler]

Watching this stuff really is fun..it's like feeling the pulse of the planet!


One question I have is why they are using different time frames for the averaging.

Temps: 1982 - 2006 used to establish the average
Extent: 1979 - 2000 used to establish the average

Now, I know that they are different data sets, gathered by different instruments.

But, for example, the ice extent data could be averaged between 1979-2006; why not?

Probably so that the extents were directly comparable to those appearing in reports made before 2006.
