Carbon emissions from warming soils could trigger disastrous feedback loop

26-year study reveals natural biological factors kick in once warming reaches certain point, leading to potentially unstoppable increase in temperatures.

Warming soils are releasing more carbon into the atmosphere than previously thought, suggesting a potentially disastrous feedback mechanism whereby increases in global temperatures will trigger massive new carbon releases in a cycle that may be impossible to break.

The increased production of carbon comes from the microbes within soils, according to a report in the peer-review journal Science, published on Friday.
