English: Schematic of the methane climate feedback loop showing how feedback mechanisms relate to each other: each feedback mechanism (within the yellow circle) is forced by climate change, altering methane emissions to the atmosphere. Direct methane feedbacks are indicated with green arrows, and indirect feedbacks are within the yellow circle. After production, methane is exposed to oxidation before being emitted to the atmosphere where it is then consumed by the atmospheric methane sink. The amount of methane in the atmosphere causes radiative forcing (the greenhouse effect) that feeds back to the overall climate forcing, completing the positive methane climate feedback loop (shown in light blue).
