GLOBAL WARMING BLAMED ON BIG BOOM

Russian scientist Vladimir Shaidurov has come up with a controversial non-greenhouse gas explanation for global warming:

The Tunguska Event, sometimes known as the Tungus Meteorite is thought to have resulted from an asteroid or comet entering the earth's atmosphere and exploding. The event released as much energy as fifteen one-megaton atomic bombs. As well as blasting an enormous amount of dust into the atmosphere, felling 60 million trees over an area of more than 2000 square kilometres. Shaidurov suggests that this explosion would have caused "considerable stirring of the high layers of atmosphere and change its structure." Such meteoric disruption was the trigger for the subsequent rise in global temperatures.

Shaidurov has to be one brave man; the humans-are-destroying-the-Earth crowd are going to crap all over him.
