It's is a computer model. It gives ice volume estimates based on satellite altimetry (post-2003), and based on NOTHING of consequence except ice extent (pre-2003).

It's not possible to derive ice volume from available data prior to 2003.

As for ice extent, "since 1970s" is a cherry-pick. Here's the IPCC's FAR:

Good!

It reduces temperature difference between high & low latitudes. It causes DECREASING temperature gradient from low to high latitude.

Now, how does that affect storms? James Hansen explains it @ 7:25

Of course he was wrong: Arctic Amplification causes DECREASING temperature gradient.

Surely, by now, he's heard of Arctic Amplification. Could it be is predictions have more to do with his politics than with science?

Say it ain't so, @DrJamesEHansen !
