May it be the same as the nuclear "winter" after the war? When scientists forgot that soot could go down and the only influence is a little cloudy day instead of the ice age. I don't negate the existence of the global warming, i've felt it myself this summer with 49 degrees on sun 2 weeks without any rain. The drought is much more probable than it was before. So many springs dissapeared due to it in the last decade. It's bad, dangerous, but still not the end of the world.

Also everyone watches the CO2 level, but what about other greenhouse gases like methane?
