Scientists Realize That A Machine Is Starting That Can't Be Stopped: "Scientists are fretting about a global warming vicious cycle that had not been part of their already gloomy climate forecasts: Warming already under way thaws permafrost, soil that had been continuously frozen for thousands of years.
Thawed permafrost releases methane and carbon dioxide. Those gases reach the atmosphere and help trap heat on Earth in the greenhouse effect. The trapped heat thaws more permafrost, and so on."
The profit crackers that pass for businessmen in this country are about to pull the finger, inviting nature to gas us all.
"'The higher the temperature gets, the more permafrost we melt, the more tendency it is to become a more vicious cycle,' said Chris Field, director of global ecology at the Carnegie Institution of Washington. 'That's the thing that is scary about this whole thing. There are lots of mechanisms that tend to be self-perpetuating and relatively few that tends to shut it off.'"
