any part of the ozone layer that has become depleted by atmospheric pollution, resulting in excess ultraviolet radiation passing through the atmosphere. [1985–90] Random House Kernerman Webster's College Dictionary, © 2010 K Dictionaries Ltd. Copyright 2005, 1997, 1991 by Random House, Inc. ...
The abnormally low concentrations of ozone recorded over Novolazarevskaya Station in October 1985 (the Antarctic spring) appear to be linked with the fact that over the past few years the duration of the spring readjustment of circulation over Antarctica (involving the collapse of the wintertime ...
Despite the enormous attention devoted to the massive springtime loss of stratospheric ozone in the Southern Hemisphere (the Antarctic Ozone Hole was recognized officially in the pages of Nature in 1985), there has been no mention in news sections of Nature of the massive ozone loss in the north...
In 1985, scientists reported a change in the atmosphere, a hole or thinning of ozone(臭氧层)over Antarctica. Scientists were not sure what was causing. Most scientists believe that man-made chemicals are destroying the ozone. They also have found signs of ozone loss in other parts of the ...

The scientists showed that the hole in the ozone layer over Antarctica, discovered in 1985, is around 4 million square miles smaller in 2014 than it was in 2000. That's the size of the entire Indian subcontinent. Scientists believe that the recovery can be attributed to the decline of ...
In 1985, just over 30 years ago, the " ozone hole " made its appearance in the press as a truly global environmental threat. As one of the most important global environmental issues of the late twentieth century, the " ozone hole " is also and maybe most importantly a remarkable ...
Nonetheless, by 1985, the British Antarctic Survey confirmed a hole in the ozone layer and suggested a link to CFCs – vindicating the work of Molina and Rowland, who were eventually awarded the 1995 Nobel Prize in Chemistry. An unambiguous call to action ...
In 1985, Farman et al. discovered the near complete disappearance of the stratospheric ozone layer over Antarctica in spring. This 'Ozone Hole' took the atmospheric research community by surprise as it could not be explained by the known catalytic cycles removing ozone in the stratosphere. McElroy...
“It’s great news for ozone in the Southern Hemisphere,” said Paul Newman, chief scientist for Earth Sciences at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “But it’s important to recognize that what we’re seeing this year is due to warmer stratospheric temperatures. It...
