Arctic Rivers Provide Fingerprint of Carbon Release from Thawing Permafrost
The feedback between a warming climate and accelerated release of carbon currently frozen into permafrost around the Arctic is one of the grand challenges in current climate research. A study published this week in the Proceedings of the National Academy of Sciences of the USA by a team of researchers led by Stockholm University used radiocarbon dating of carbon in four large Siberian-Arctic rivers to pinpoint the patterns of old carbon release from permafrost across northern Eurasia.
