The Earth may be able to recover from rising carbon dioxide emissions faster than previously thought, according to evidence from a prehistoric event. When faced with high levels of atmospheric carbon dioxide and rising temperatures 56 million years ago, the Earth increased its ability to pull carbon from the air. This led to a recovery that was quicker than anticipated by many models of the carbon cycle.
