Researchers locate carbon reserve six feet below the soil's surface
Nov. 26 (UPI) -- At least a quarter of all the carbon stored in Earth's soil is found locked up in minerals roughly six feet beneath the surface. But new research suggests this unique carbon reservoir will become less efficient at carbon storage as the planet warms. To better understand how rising carbon dioxide levels in the atmosphere will impact the planet's climate, scientists need to more accurately model Earth's many carbon cycles. Soil hosts one of those carbon cycles. As part of a new survey, the first of its kind, researchers detailed the way carbon physically and chemically binds to minerals in soils across the globe. The results of the survey were published Monday in the journal Nature Climate Change. "We know less about the soils on Earth than we do about the surface of Mars,"...
