Andy Lee Robinson does a lot of excellent graphics about Arctic sea ice. This one is spectacularly good.

(Moan, grumble, complain. Why is it that some people are so talented in so many ways? Robinson did the graphics and the animation and he also performed the music in the background which he wrote.)
Aaaaand, the whole Chasing Ice video is now online.
