BOULDER, Colo., Feb. 16 (UPI) -- Up to two-thirds of the Earth's permafrost could thaw by 2200 because of warming temperatures, releasing carbon into the atmosphere, U.S. scientists said.
The study by the University of Colorado Boulder's Cooperative Institute for Research in Environmental Sciences indicated the higher levels of carbon would impact not only the climate but also global strategies to reduce fossil fuel emissions, lead author Kevin Schaefer said Wednesday in a release.
