“Concentration vs. Extent“. Steven Goddard plays word games to try to slip out of his unsupported Arctic Sea Ice claims. He’s nothing if not intransigent!

Steven used to argue about ice extent (surface area) but the ice volume facts completely undercut his position. Now he’s talking about ice “concentration”. This is pretty much just a variation on volume, but it lets him slip away from his claims about extent.

To do this though Steven has to baldly claim that his chosen model, PIPS 2.0, is the proper one to use because it’s the only one that he can use to claim that “concentration” is not collapsing too. The better model is PIOMAS, but unfortunately it doesn’t support his claims.

Funny how quickly the outrage over using “models” disappears when denialists like Steven find one that they think they can exploit.

How ’bout the numbers? Arctic sea ice extent is currently about 270,000 km² lower than the “record low” of 2007. Arctic sea ice volume is also down since then, by about 300 km³.
