Our Dimming Sun
Yep, that what newest research has found. It seems that clearer skies let in more sunlight and caused higher average temperatures in western Europe. Please see link below.

This comes as no surprise to me because a PBS NOVA report named “Our Dimming Sun” showed a chart on how the temperatures over the U.S. rose several degrees when airliners were grounded for 4 days following the 9-11 disaster. The chart went straight up several degrees when the planes were all grounded and dropped down to previous levels when flights resumed. This, all due to the lack of the vapor/ice trails that Jets produce when they fly at very high altitudes. Without these white trails to reflect sunlight back into the atmosphere, more sunlight reached the earth making it noticeably warmer for those four days.
The PBS special also showed that the increasing pollution over China and India is reducing sunlight reaching those areas and thereby reducing temperatures and evaporation. Thus the title “Our Dimming Sun”.

So, my conclusion is that if you want cleaner skies, you have to except any Global warming that we artificially produce. I have a good idea, let nature do it's job without man interfering. Mother Nature did an excellent job of protecting our world for many billions of years, who are we to try to undo such a successful record.
