Snow

Re Ice. It seems sea ice extent is on a gradual increase in the Antarctic while on a decrease in the arctic - since 1979. What's that about?

The data in that webpage show no clear trend at all in the Antarctic, whereas there is a clear decrease in the Arctic.

In any case, increasing temperatures in very cold regions can lead to more ice. Air at -10C can hold more water vapour than air at -20C, so an increase in temperature in that range can lead to more precipitation, which would still fall as snow.
