Actually, I hadn't. Apparently I'm a Lazyass.

Assuming this is true, the point of the politics behind global warming isn't that the entire globe is warming, it's that we are F'ing up the planet. Some places warmer, some colder, some smoggier, beaches creeping in, ecosystems collapsing, etc. Finding some place in the world that is getting colder doesn't mean pollution is good for the world.

Edit - I just did my research and 90% of what I find says that while small parts are growing, this is due to the much larger meltoff on the thinner edges, which is causing more snow to fall, thus increasing the thicker central areas.
