Permafrost Melt Soon Irreversible Without Major Fossil Fuel Cuts By Stephen Leahy: "UXBRIDGE - Thawing permafrost is threatening to overwhelm attempts to keep the planet from getting too hot for human survival.
Without major reductions in the use of fossil fuels, as much as two-thirds of the world's gigantic storehouse of frozen carbon could be released, a new study reported. That would push global temperatures several degrees higher, making large parts of the planet uninhabitable."
