The truth is now out, research has shown that trees, the wicked things, produce an extra 150m tonnes of methane every year. If a similar proportion of this, say 6m tonnes, remain in the atmosphere, it will only raise the temperature of the atmosphere by just over one-thousandth of a degree Celsius. Certainly not enough to worry about but surely enough to blow IPCC’s credibility away.
