George Washington was onto something. 260 years (give or take 10 or so) before Kyoto he was trying to save the Earth. He chopped down that obnoxious cherry tree to help clean the air.
Trees contribute "10 to 30% of the world's methane emissions". Just when I was going to abandon the car for the bicycle the easier answer of chopping down a few trees presents itself. Dairy farmers are happy about this too. Trees' emissions are far greater than cows'.
Seriously, if this is true and science has missed it until now, what else are they missing in those climate models? Planting trees was a key part of Kyoto, but now it seems that planting trees may not be such a great idea after all. Back to the drawing board, I guess.
