News at the North Pole Ozone Layer

ENN, March 16, 2011

Unusually low temperatures in the Arctic ozone layer have recently initiated massive ozone depletion. The Arctic appears to be heading for a record loss of this trace gas that protects the Earth's surface against ultraviolet radiation from the sun. This result has been found by measurements carried out by an international network of over 30 ozone sounding stations spread all over the Arctic and Subarctic and coordinated by the Potsdam Research Unit of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association in Germany.

Antarctic Sea Ice Paradoxically Growing

ENN, June 18, 2010

While Arctic sea ice continues to shrink as the world warms, the ice around Antarctica is actually growing, thanks to the influence of the ozone hole over the southernmost continent, scientists have reported.But the south polar growth won't be permanent, they warn. Though they are headed in opposite directions, the current conditions at both poles are affected by human impacts on the climate, said John Turner of the British Antarctic Survey, who presented these findings to the International Polar Year (IPY) conference held last week in Oslo, Norway.

The Ozone hole is filling in, oh no!

ENN, January 26, 2010

According to research at the University of Leeds, the hole in the ozone layer is now steadily closing. This is a concern, since its repair could actually increase warming in the southern hemisphere, the scientists at Leeds conclude. Read more...

British Antarctic Survey Climate Review finds the Ozone Hole has Shielded Antarctica from Global Warming!

ENN, December 01, 2009

An important report from the British Antarctic Survey (BAS) shows things aren’t always what they seem to be, and that our knowledge of our complex Earth is not a good as we thought. Sometimes problems are not what they seem to be, and sometimes a problem in one sense carries unknown benefits in other senses. Professor John Turner of British Antarctic Survey is the lead editor of the review. He said,“For me 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". Read more...
