Prodding the bottom of a thermokarst lake in northeastern Siberia releases bubbles of methane and carbon dioxide. Large quantities of organic matter are stored in permafrost soils. As the permafrost thaws, bacteria can decompose the ancient organic matter, which produces methane and carbon dioxide. Methane is an important greenhouse gas and has a warming potential of 25 compared to carbon dioxide over a 100-year period.
