Antarctic ozone hole linked to warming in southern Africa

A decades-long warming trend in southern Africa is likely the result of the ozone hole over the Antarctic and its effect on wind circulation, researchers say.
In early summer southern Africa is affected by what is known as the Angola Low, a low-pressure system that pulls in warm air from the lower latitudes, increasing temperatures.
But during the past 20 years, the researchers said, the annual rise in temperatures has been nearly two degrees Fahrenheit hotter than normal.
Desmond Manatsa, a climate scientist at Bindura University of Science in Zimbabwe, working with international colleagues, analyzed climate data from 1979 to 2010, and found as the size of the ozone hole -- caused by human use of fluorocarbons -- grew, temperatures in southern Africa rose as well.
