Global Dimming
 

Interesting transcript from BBC:

Some of the science at the end is a bit shaky at best (Travis' evidence) but it's an interesting read and a very scary view of the future.

I didn't read the entire thing, there are a few things I noticed though...

If anyone has ever done any research whatsoever on global warming, then they also know that global cooling was also theorized back in the 50s-70's. Hell, scientists promoted that theory as much as scientists today do about global warming.

Pan evaporation....well, even a hundred years of measurements isn't a blink of the eye in compared to the age of earth. A hundred years definitly would not hold up in a statistical analysis of the changes.

Also, I've always read that when dealing with heat exchange humidity has a LOT more to do with evaporative cooling than sunlight. Basically, the higher the humidity, the less evaporation occurs. At 100% there is little to no evaporation...
