FSU: Thawing Permafrost Feeds Climate Change

Carbon, held in frozen permafrost soils for tens of thousands of years, is being released as Arctic regions of the Earth warm and is further fueling global climate change, according to a Florida State University researcher.

Assistant Professor of Oceanography Robert Spencer writes in Geophysical Research Letters that single-cell organisms called microbes are rapidly devouring the ancient carbon being released from thawing permafrost soil and ultimately releasing it back into the atmosphere as carbon dioxide. Increased carbon dioxide levels, of course, cause the Earth to warm and accelerate thawing.
