worse than we thought – amplifying feedbacks!

Climate change will be much worse, much sooner than most people think. The United Nations Intergovernmental Panel on Climate Change (UN IPCC) recent report, while rather dire, is actually a best-case analysis.

For example, the IPCC’s report did not include the effects of “amplifying feedbacks” such as melting permafrost releasing methane — a powerful greenhouse gas — which causes more warming, which melts more permafrost, and on and on.

Including such effects leads to much more dire results than the UN presented.
