Earth has regulated its climate for 60 million years through a hidden ocean feedback

A new study has identified a natural process that may have helped keep Earth's climate stable for the past 60 million years. Researchers found that changes in sea level controlled the amount of phosphate reaching the oceans, affecting marine life, carbon burial beneath the seafloor and the level of carbon dioxide in the atmosphere. The findings offer a new explanation for how Earth naturally regulated long-term warming and cooling.
