In the Southern Ocean, a Carbon-Dioxide Mystery Comes Clear
Twenty thousand years ago, low concentrations of carbon dioxide in the atmosphere allowed the earth to fall into the grip of an ice age. But despite decades of research, the reasons why levels of the greenhouse gas were so low then have been difficult to piece together. New research, published today in the leading journal…
