New ground truth: soil microbe negative feedback

This could be a game changer. From the University of California, Irvine press release, a finding that suggests soil microbes have a negative feedback with temperature increase. This has broad implications for the amount of CO2 emitted estimated in climate models. It had been assumed that as temperature increased, microbes and fungii would increase their CO2 output. Globally, this microbiotic contribution is large.  The amount of CO2 released from soils worldwide each year is estimated to be about 8-10 times greater than the amount released by humans.

This study shows that soil microbes won’t go into a an “overdrive” mode when soil temperature increases.
