This diagram from NASA gives an intesting view of Global Warming.

The warmest regions are in Eastern Siberia and Alaska. However, Eastern USA
and the sea around Antarctica are showing cooling. That allows some idiots
to claim that the warming is not global, but it is very significant none the
less.
