Figure 3. Increases in decadal averaged (2091–2100) annual CH 4 emission (Tgyr −1 , poleward of 45° N) with respect to 2011–20 as a result of the warming and expansion of yedoma lakes (Y), non-yedoma (NY) lakes, wetlands (W), and total inundated areas for the low and high TCR under the UCE and GST scenarios, respectively. Each scenario contains 18 ensemble members (17 members of model-based pattern shifts and one member of climatological pattern). Whisker plots show the minimum, maximum, and plus/minus one standard deviation about the ensemble mean. Abstract Climate change and permafrost thaw have been suggested to increase high latitude methane emissions that could potentially represent a strong feedback to the climate system. Using an integrated earth-system model framework, we examine the degradation of near-surface permafrost, temporal dynamics of inundation (lakes and wetlands) induced by hydro-climatic change, subsequent methane emission, and potential climate feedback. We find that increases in ...
