A two-decade-long rise in early summer temperatures across southern Africa may have been caused by ozone loss over the South Pole, researchers say. "The temperatures were actually significantly higher than those of other seasons and the rising assumed a shift rather than a slow and gradual manner," said climate scientist Desmond Manatsa of the Bindura University of Science Education in Zimbabwe. By analyzing climate data between 1979 and 2010, researchers found that the size of the ozone hole sparked an upward shift in temperatures in the area, according to a report in Nature Geoscience.
