Remote ocean has doubled its intake of the greenhouse gas since 2000, reversing an earlier decline.

The Southern Ocean, which each year soaks up billions of tonnes of carbon dioxide from the atmosphere, has reversed a worrying decline in its annual intake of the greenhouse gas.

But the study1 — which pulls together millions of scattered field observations — brings a much clearer understanding of the variable activity of the Southern Ocean as the world’s most important buffer against global warming. The work was published on 11 September in Science.
