Methane release from melting permafrost could trigger dangerous global warming | John Abraham

A policy briefing from the Woods Hole Research Center concludes that the IPCC doesn't adequately account for a methane warming feedback

While most attention has been given to carbon dioxide, it isn't the only greenhouse gas that scientists are worried about. Carbon dioxide is the most important human-emitted greenhouse gas, but methane has also increased in the atmosphere and it adds to our concerns.

While methane is not currently as important as carbon dioxide, it has a hidden danger. Molecule for molecule, methane traps more heat than carbon dioxide; approximately 30 times more, depending on the time frame under consideration. However, because methane is present in much smaller concentrations (compared to carbon dioxide), its aggregate effect is less.
