How on Earth can global warming deniers be using Arctic sea ice as evidence against AGW?

I think the approach they're taking is that the AGW doomsayers where rather spectacularly wrong about the complete loss of Arctic ice this summer, so you begin to wonder what else are they wrong about.

I don't know Dana, but I'll bet you $100.00 US, that September 15, 2009 will have more arctic sea ice than September 15, 2008. Ok Dana: Your on!

Actually the ice is thicker than it was at 1979 levels: http://igloo.atmos.uiuc.edu/cgi-bin/test/print.sh?fm=10&fd=12&fy=1979&sm=10&sd=12&sy=2008 Pinkish purple is 80% concentration and dark purple is 100% concentration. Also the faster it forms before the main part of the deep freeze occurs in December, January and February the thicker it will be in June, July and August.

That's easy D, it did not behave as the doomsayers predicted. If they're wrong about this, they're firing shots in the dark at the rest of it, too.

The last few years has actually seen the planet's temperature cool.

why did the Earth's temerature rise and fall before we drove SUV's and ruined the planet? Just wondering........

I thought you were going to provide a link of some semi-reputable denier actually, er, denying on those grounds. Instead all you give us is scientific data from a reputable organisation! Where is the 'debate', where are these deniers? A bunch of troll like folk on YA! adds up to not very much at all. If you are reffering to them then why are you bothering?

my goodness, i've heard it's cooling since 1998. is that really true? i wonder where we could see such results? http://igloo.atmos.uiuc.edu/cgi-bin/test/print.sh?fm=10&fd=11&fy=1998&sm=10&sd=11&sy=2008 uh oh, seems like lots less arctic ice in 2008 than 1998. maybe it's not cooling. Don't like those dates? pick your own. you'll be working pretty hard to show that there's more ice anywhere in 2008 than there was if 1998.

I agree, it is ridiculous, but I have a few problems with some of your specifics: "Arctic sea ice melt broke the record of 2007 in terms of volume." I don't know how you could say this so definitively. William Connolley explains the difficulty with measuring sea ice volume here http://scienceblogs.com/stoat/2008/10/sea_ice_thinner.php#more
