Methane, an extremely potent greenhouse gas, is increasing fast in our atmosphere — both from industrial emissions AND from "natural" sources triggered by global warming, which then cause more global warming, and so on, and so on...

New research shows that feedbacks in the climate system are boosting methane emissions from natural sources, especially tropical wetlands.
Scientists say that an abrupt surge in methane emissions in the early 2000s is probably due mainly to the response of wetlands to warming, with additional contributions coming from fossil fuel use, “implying that anthropogenic emissions must decrease more than expected to reach a given warming goal.”
Increasing rainfall, a well-documented impact of global warming, is making wetlands larger and wetter, and a warmer world fosters more plant growth, which means more decomposing material that emits methane.
About 60% of methane emissions are from fossil fuel use, farming, landfills, and waste, with the rest c

Increasing rainfall, a well-documented impact of global warming, is making wetlands larger and wetter, and a warmer world fosters more plant growth, which means more decomposing material that emits methane.
About 60% of methane emissions are from fossil fuel use, farming, landfills, and waste, with the rest coming from rotting vegetation in wetlands in the tropics and Northern Hemisphere.
A new trouble spot is in the Arctic, where scientists recently found unexpectedly large methane emissions in winter. And globally, the increase in water vapor caused by global warming is slowing the rate at which methane breaks down in the atmosphere.

New studies suggest global warming boosts natural methane releases, which could undermine efforts to cut emissions of the greenhouse gas from fossil fuels and agriculture.
