Arctic lakes could accelerate CO2 emissions


Today’s Video of the Day from NASA Goddard describes a potentially underestimated threat from Arctic warming, as rising temperatures allow permafrost to thaw and release carbon dioxide that has been stored in the frozen soil for centuries.

Thermokarst lakes can form when snowmelt collects into areas of the ground that have slumped from thawing permafrost. A study funded by NASA has found that the formation of these lakes could accelerate the rate that carbon dioxide is released into the atmosphere.
