Climate change affects Southern Ocean carbon sink
The first evidence that recent climate change has weakened one of the Earth’s natural carbon ‘sinks’ was published recently in the journal Science.
A four-year study by scientists from the University of East Anglia (UEA), British Antarctic Survey (BAS) and the Max-Planck Institute for Biogeochemistry reveals that an increase in winds over the Southern Ocean, caused by greenhouse gases and ozone depletion, has led to a release of stored CO2 into the atmosphere and is preventing further absorption of the greenhouse gas.
