Waming is causing permafrost to melt releasing methane causing even faster warming

Warming of Arctic causes permafrost to melt.   The Arctic is warming much faster than rest of earth (4 degrees F), meaning that permafrost is also melting rapidly, releasing methane CH4 that is 25 to 100 times more powerful as a greenhouse gas than carbon dioxide CO2.  Our computer models are based on CO2 and even slight changes in angles of a molecule can cause radical changes in behavior.......Perhaps this is why catastrophic rates and intensities of unprecedented storms around the globe have alarmed scientists who had used CO2 models to predict changes.
