Ozone loss warmed southern Africa

Nature

Antarctic ozone hole’s effects may have spread much wider than thought.

Ozone loss over the South Pole might be the reason for a two-decade rise in early summer temperatures across southern Africa, according to research published today inĀ Nature Geoscience1.

Desmond Manatsa, a climate scientist at Bindura University of Science in Zimbabwe, and colleagues analysed data sets of southern African climate from 1979 to 2010, covering the

Arctic Ocean full up with carbon dioxide

Loss of sea ice is unlikely to enable Arctic waters to mop up more carbon dioxide from the air.

As climate scientists watched the Arctic’s sea-ice cover shrink year after year, they thought there might be a silver lining: an ice-free Arctic Ocean could soak up large amounts of CO2 from the atmosphere, slowing down the accumulation of greenhouse gases and climate change.

But research published in Science today … Read the rest
