Soil Can Sequester Planet-Warming Carbon. The Merced River is Helping Scientists Understand How.

Soils are carbon sinks, storing more planet-warming carbon than the atmosphere and all animal and plant life combined.

But they can also release massive amounts of stored carbon into the atmosphere. Given carbon’s central role in climate change, understanding the forces that govern how soils absorb and release carbon is crucial.
