For decades, scientists have speculated that rising global temperatures might alter the ability of soils to store carbon, potentially releasing huge amounts of carbon into the atmosphere and triggering runaway climate change. Yet thousands of studies worldwide have produced mixed signals on whether this storage capacity will actually decrease — or even increase — as the planet warms. It turns out scientists might have been looking in the wrong places.
