Warming Will Unlock Carbon in Forests, Study Warns http://apocadocs.com/s.pl?1339526340
...scientists have identified another feedback loop that may be accelerating the loss of carbon dioxide from the topsoil of forests in the United States, contributing to climate change. In a study published online on Monday, researchers at the University of California, Irvine, and the Lawrence Berkeley National Laboratory found that as temperatures rise, activity increases among the microbes that eat the topsoil and exhale carbon dioxide afterward.
While that finding is not surprising, said the lead author, Francesca Hopkins, a doctoral researcher in the Department of Earth System Science at Irvine, she and her collaborators also found that in warmer temperatures the microbes were better able to digest decades-old carbon stored in the soils.
