Forests may not help mitigate carbon dioxide pollution thanks to an uptick in CO2 emissions from decomposition

 

As higher levels of carbon dioxide permeate the Earth's atmosphere, scientists have long counted on forests -- which, as individual trees, grow larger in carbon-rich environments -- to soak up some of the excess.

But after nearly a decade and a half of observing forest ecosystems in controlled settings, scientists now see evidence that elevating carbon levels may cause forests to release as much extra carbon as they absorb.
