Thawing permafrost also delivers organic - rich soils to lake bottoms, where decomposition
in the absence of oxygen releases additional methane.116 Extensive wildfires also release
carbon that contributes to climate warming.107, 117,118 The capacity of the Yukon River Basin
in Alaska and adjacent Canada to store
carbon has been substantially weakened since the 1960s by the combination of warming and thawing of permafrost and by increased wildfire.119 Expansion of tall shrubs and trees into tundra makes the surface darker and rougher, increasing absorption of the sun's energy and further contributing to warming.120 This warming is likely stronger than the potential cooling effects of increased
carbon dioxide uptake associated with tree and shrub expansion.121 The shorter snow - covered seasons
in Alaska further increase energy absorption by the land surface, an effect only slightly offset by the reduced energy absorption of highly reflective post-fire snow - covered landscapes.121 This spectrum of changes

carbon management to offset fossil fuel
emissions.94, 95,96
