BALANCE: CLIMATE FEEDBACK MAY NOT BE AS BAD AS THOUGHT.I looked for Turetsky's study and found this press release linking to this abstract
One of the global warming nightmares is that thawing permafrost might release methane, a potent greenhouse gas. This positive feedback would accelerate warming. A group led by M. Turetsky of Michigan State found that new plant growth in thawing Canadian peat bogs more than offset the release of methane.
The only thing we can be sure of about the future is that it will be absolutely fantastic. So if what I say now seems to you to be very reasonable, then I have failed completely. Only if what I tell you appears absolutely unbelievable, have we any chance of visualizing the future as it really will happen.
