Saw this article at the Times.

This article is about change at the icecaps, that they are melting, and will continue to melt.  The "point of no return" is almost upon us. 

There is still debate on whether this all man-made, or whether some of the effect is a warming that occurs naturally.

At any rate, things are different now at the polar icecaps, than they have been, and will be more different in the near future.
