But the effects for most of the world will be devastating!
The most pessimistic predictions were that the permafrost might be melting away like this by the middle of the century. If it's happening now, it suggests that the carbon sinks are much more sensitive to warming than was thought and global warming will be much worse. Forget about the IPCC's 1.4 to 5.8 degrees C warming this century - think 6 to 12 degrees. Those kind of rises would turn most of the world to desert and make most life on Earth extinct.
