Watch Out Where the Mammoths Go
By Jodi LaMarco
Scientist Sergei Zimov believes that as ice-melt releases ancient organic matter from arctic permafrost, exposed materials will begin to break down, thus fueling global warming.
Materials locked in ice, such as mammoth dung, can emit CO2 and methane once bacteria are again exposed to the air.
According to Zimov, chief scientist at the Russian Academy of Science's North Eastern Scientific station, "Permafrost areas hold 500 billion tons of carbon, which can fast turn into greenhouse gases. If you don't stop emissions of greenhouse gases into the atmosphere...the Kyoto Protocol will seem like childish prattle."
