Ozone hole saves Antarctic from global warming

Tue Dec 1, 2009

Amid global concern over depletion of the ozone layer, scientists have said the ozone loss cooled the Antarctica by shielding it from global warming.

Reports conducted by the Scientific Committee on Antarctic Research (SCAR) suggest the positive impact the environmental catastrophe of ozone hole on protecting Antarctica from global warming.

Scientists said Antarctica has been protected from the global warming's damaging effects by the ozone layer hole, the impact of one of the worst environmental disasters of the 20th century.

The hole in the ozone layer was caused by the release of chlorofluorocarbon (CFC) gases. The hole, however, has cooled temperatures and shielded most of Antarctica from global warming, the report found.

"The most astonishing evidence is the way that one man-made environmental impact, the ozone hole, has shielded most of Antarctica from another, global warming," said John Turner, head of climate research for the British Antarctic Survey and lead editor for the review.

The study has also found South Pole sea levels will rise 1.4 meters globally by 2100 as polar ice melts.
