Polar Ocean Is Sucking Up Less Carbon Dioxide

The ability of the Southern Ocean to remove carbon dioxide from the atmosphere is being eroded by climate change, say environmental researchers. If the trend continues, then the ability of this 'carbon sink' to deal with humankind's greenhouse emissions will be impaired. Roughly half of the carbon dioxide that enters the atmosphere is absorbed by the world's oceans, so as greenhouse emissions increase, the amount taken up by the oceans should increase in proportion...
