So it really is a polluting particle. Even Obama's scientist admit it.

Many report hotter, unfriendly sun, no wind when the sky is white though. So that maybe just an unproven theory.

Obama May Block Sun's Rays to End Global Warming - Science News | Science & Technology | Technology News - FOXNews.com
WASHINGTON — The president's new science adviser said Wednesday that global warming is so dire, the Obama administration is discussing radical technologies to cool Earth's air.
John Holdren told The Associated Press in his first interview since being confirmed last month that the idea of geoengineering the climate is being discussed.
One such extreme option includes shooting pollution particles into the upper atmosphere to reflect the sun's rays. Holdren said such an experimental measure would only be used as a last resort.
"It's got to be looked at," he said. "We don't have the luxury of taking any approach off the table."

Why would particles in the atmosphere cause global dimming?
It's very simple - they reflect sunlight back into space. This fact has been well-known for many decades (it is why volcanoes, which can throw vast numbers of sulphate particles into the upper atmosphere, can have a strong temporary cooling effect on the Earth).
What came as a surprise was the so-called indirect effect, whereby particles in the atmosphere change the optical properties of clouds. This happens because the presence of man-made particles in the atmosphere increases the number of sites where water droplets can form. The effect is that up to six times as many water droplets form in a polluted air mass as would naturally, but since the amount of water vapour in the atmosphere does not change, the droplets have to be smaller than they would naturally be.
Since the reflectivity of the clouds depends on the surface area of the droplets, these polluted clouds are more reflective than unpolluted ones (since many small droplets have a bigger surface area than fewer big ones). By reflecting more sunlight back into space these more reflective clouds cut down the sunlight reaching the surface - hence contributing to global dimming.
