The Last Frost

While browsing this page on the EPA's website today, I noticed two maps that I found very interesting. In map #1 you see the average global warming trend, red being warming, blue meaning cooling. In map #2 you see a map of what is effectively global dimming due to atmospheric sulfates. Blue and white being a reduction in solar radiation reaching the surface.

If you look at the two together something starts to pop out… check out Map #3. The warming trend seems to be reduced by the increased atmospheric sulfate concentrations. The interesting thing is that according to the EPA, sulfates clear out of the atmosphere within just a few weeks. It seems like there's some truth to the theories that global dimming is hiding the true effects of global warming. If and when we stop producing atmospheric sulfates things may change very rapidly.

See the maps after the jump.
