The soil beneath our feet is a huge carbon bank storing up to approximately three times more carbon than the entire atmosphere. That makes it a significant player in the future of our climate. If even a small fraction of the carbon escapes into the air as carbon dioxide, it could accelerate planetary heating. But what determines whether the carbon stays in the ground or escapes? According to new research published in the journal Nature Climate Change, water is the deciding factor. The wetter the soil, the more carbon stays in the ground.
