Ozone depletion is a major climate driver in the southern hemisphere
When people hear about the dangers of the ozone hole, they often think of sunburns and associated health risks, but new research shows that ozone depletion changes atmospheric and oceanic circulation with potentially devastating effects on weather in the Southern Hemisphere weather.  View News Article (2014-12-02)

NASA Study Finds Clock Ticking Slower On Ozone Hole Recovery
The Antarctic ozone hole's recovery is running late. According to a new NASA study, the full return of the protective ozone over the South Pole will take nearly 20 years longer than scientists previously expected. View News Article (2006-06-30)

NASA's AURA satellite peers into Earth's ozone hole
NASA researchers, using data from the agency's AURA satellite, determined the seasonal ozone hole that developed over Antarctica this year is smaller than in previous years. View News Article (2005-12-07)

Geological reasons of ozone layer destruction
The modern science admits that the ozone concentration in the stratosphere is diminishing. This process has been fixing since the middle of 1980s. "The most popular hypothesis about technogenic freon that destroys the ozone layer is quite vulnerable", - said Dr. of geology Vladimir Sivorotkin who studies the problem of the ozone layer for ten years. Freon is used mainly as a vaporising fluid in... View News Article (1999-10-19)

Low Temperatures Enhance Ozone Degradation above the Arctic
Extraordinarily cold temperatures in the winter of 2010/2011 caused the most massive destruction of the ozone layer above the Arctic so far: The mechanisms leading to the first ozone hole above the North Pole were studied by scientists of the KIT Institute of Meteorology and Climate Research (IMK).  View News Article (2012-01-20)

As ozone hole approaches annual peak, NASA scientists reveal latest information and images
In 1987, the United States joined several other nations in signing the Montreal Protocol, an international treaty designed to protect the Earth's ozone layer by phasing out the production of a number of substances believed to be responsible for ozone depletion. View News Article (2006-09-29)

NASA Reveals New Results From Inside the Ozone Hole
NASA scientists have revealed the inner workings of the ozone hole that forms annually over Antarctica and found that declining chlorine in the stratosphere has not yet caused a recovery of the ozone hole. View News Article (2013-12-12)

Annual Antarctic ozone hole larger and formed later in 2015
The 2015 Antarctic ozone hole area was larger and formed later than in recent years, said scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA). View News Article (2015-10-30)

2014 Antarctic Ozone Hole Holds Steady
The Antarctic ozone hole reached its annual peak size on Sept. 11, according to scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA). The size of this year's hole was 24.1 million square kilometers (9.3 million square miles) - an area roughly the size of North America. View News Article (2014-10-31)

European low-ozone event reveals worrying trend
For several days last week, the protective ozone layer over Europe thinned considerably. Scientists monitoring ozone coverage using a rapid mapping technique based on data from the GOME (Global Ozone Monitoring Experiment) instrument aboard ESA`s ERS-2 satellite detected finger-like ozone thinning over Europe. "From 28-30 January, we observed a pronounced `streamer event`," explains DLR`s Thilo... View News Article (2002-02-06)
