Polar ocean soaking up less CO2

by Simon Hilton on Fri 18 May 2007

One of the Earth’s most important absorbers of carbon dioxide (CO2) is failing to soak up as much of the greenhouse gas as it was expected to.
The decline of Antarctica’s Southern Ocean carbon “sink” – or reservoir – means that atmospheric CO2 levels may be higher in future than predicted.
These carbon sinks are vital; they mop up excess CO2 from the atmosphere, slowing down global warming.
The study, by an international team, is published in the journal Science.
This effect had been predicted by climate scientists, and is taken into account – to some extent – by climate models. But it appears to be happening 40 YEARS AHEAD OF SCHEDULE.
