Trees: A leading source of global warming

From the Financial Times:
But now it seems we need to think again. In a discovery that has left climate scientists gasping, researchers have found that the earth's vegetation is churning out vast quantities of methane, a greenhouse gas far more potent even than CO2. This is not a product of trees and plants rotting, which everyone already knew was a source of methane; it is an entirely natural side-effect of plant growth that scientists had somehow missed. Yet it is by no means trivial: preliminary estimates suggest that living trees and plants account for about 10 to 30 per cent of the methane entering the atmosphere.

(Tongue in cheek alert!) This means two things. First, thank goodness all those rainforests were cleared or we'd be living on a mini sun right now. Second, clear cutting is good after all!
