Some scientists believe that global warming will trigger a new ice age. Greenland's glaciers have been moving more rapidly into the sea lately thus producing more icebergs. So it is assumed that Greenland's ice shelf is melting rapidly but satellite data shows that more moisture is falling as snow over Greenland and that the ice shelf actually grew higher (2 or 3 inches).
If more moisture falls as snow over northern Canada and Siberia then sunlight in those areas will be reflected back into space, the snow will not melt and next season it will pile up even higher, and within a few thousand years it could be huge... another ice age.
There are huge ice shelves in Antarctica that polar bears could live off. If the planet is warming up maybe the south pole could be a little more hospitable on the coast lines and ice shelves.
There are plenty of seals to eat down there. Would it be a problem for the Penguins?
