Genghis Khan has been branded the greenest invader in history - after his murderous conquests killed so many people that huge swathes of cultivated land returned to forest. The Mongol leader, who established a vast empire between the 13th and 14th centuries, helped remove nearly 700million tons of carbon from the atmosphere, claims a new study.
The deaths of 40million people meant that large areas of cultivated land grew thick once again with trees, which absorb carbon dioxide from the atmosphere. And, although his methods may be difficult for environmentalists to accept, ecologists believe it may be the first ever case of successful manmade global cooling.
Not so fast with those conclusions. Turns out that trees (all plants actually) produce methane, a greenhouse gas far more potent than carbon Dioxide. If it were that simple, it seems reasonable to conclude that cool or icehouse temperatures dominate all time before man arrived on the scene. CO2 is clearly not the critical component in global climatic changes. Sun activity most likely has the dominant extrinsic control on earth climate and that along with continental drift fits the global climatic swings of the geologic past.

Hey Doc if continents can drift does that mean that congressman Johnson was onto something when he said Guam would tip over and capsize? :pop

Perhaps he could have used the term subducted instead lol Then again, if Guam ends up in a collision zone, it could well be tipped and crushed. The problem is we might have to wait a hundred million years to bring it all to fruition.
