Methane feedbacks to the global climate system in a warmer world
Methane (CH 4 ) is produced in many natural systems that are vulnerable to change under a warming climate, yet current CH 4 budgets, as well as future shifts in CH 4 emissions, have high uncertainties. Climate change has the potential to increase CH 4 emissions from critical systems such as wetlands...

Methane (CH 4 ) is produced in many natural systems that are vulnerable to change under a warming climate, yet current CH 4 budgets, as well as future shifts in CH 4 emissions, have high uncertainties. Climate change has the potential to increase CH 4 emissions from critical systems such as wetlands, marine and freshwater systems, permafrost, and methane hydrates, through shifts in temperature, hydrology, vegetation, landscape disturbance, and sea level rise. Increased CH 4 emissions from these systems would in turn induce further climate change, resulting in a positive climate feedback. Here we synthesize biological, geochemical, and physically focused CH 4 climate feedback literature, bringing together the key findings of these disciplines. We discuss environment-specific feedback processes, including the microbial, physical, and geochemical interlinkages and the timescales on which they operate, and present the current state of knowledge of CH 4 climate feedbacks in the immediate and distant future. The important linkages between microbial activity and climate warming are discussed with the aim to better constrain the sensitivity of the CH 4 cycle to future climate predictions.
