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 More (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 More (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 More (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).

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 More (2006-09-29)
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 More (2002-02-06)
Laughing Gas in a Vicious Circle
Italian researchers discover another mechanism for the formation of atmospheric N2O Summer smog, the ozone hole, the greenhouse effect – the complex web of chemical reactions in the atmosphere, which leads to manifold environmental problems, is still not fully cleared up. In a tricky way, a single chemical compound is found at the center of the action: laughing gas (N2O). A group of Italian... View More (2001-05-15)
2008 ozone hole larger than last year
The 2008 ozone hole - a thinning in the ozone layer over Antarctica - is larger both in size and ozone loss than 2007 but is not as large as 2006. View More (2008-10-08)
Antarctic forecast: premature break-up of ozone hole this week
Based on satellite data from the European Space Agency, the national meteorological centre of the Netherlands predicts the Antarctic ozone hole will break apart this week, months earlier than usual. A scientist at the Royal Netherlands Meteorological Institute (KNMI) adds that the depth of the ozone hole is much smaller than previously seen. "This breakdown is occurring exceptionally early in...

AWI-Scientist Markus Rex Receives Dobson-Award
For his work on interactions between climate change and the ozone layer, Dr Markus Rex of the Alfred Wegener Institute for Polar and Marine Research (Research branch Potsdam) received the 'Dobson-Award' on May 31, 2004. The Quadrennial Ozone Symposium in Greece was chosen to present the award for the first time. Markus Rex was honoured for his publication "On the unexplained stratospheric... View More (2004-06-25)
NOAA, NASA: Significant ozone hole remains over Antarctica
The Antarctic ozone hole, which yawns wide every Southern Hemisphere spring, reached its annual peak on September 12, stretching 10.05 million square miles, the ninth largest on record. Above the South Pole, the ozone hole reached its deepest point of the season on October 9 when total ozone readings dropped to 102 Dobson units, tied for the 10th lowest in the 26-year record.

Computer models show major climate shift as a result of closing ozone hole
A new study led by Columbia University researchers has found that the closing of the ozone hole, which is projected to occur sometime in the second half of the 21st century, may significantly affect climate change in the Southern Hemisphere, and therefore, the global climate. View More (2008-06-13)
NASA and NOAA Announce Ozone Hole is a Double Record Breaker
NASA and National Oceanic and Atmospheric Administration (NOAA) scientists report this year's ozone hole in the polar region of the Southern Hemisphere has broken records for area and depth. View More (2006-10-23)
Chemicals that eased one environmental problem may worsen another
Chemicals that helped solve a global environmental crisis in the 1990s - the hole in Earth's protective ozone layer - may be making another problem - acid rain - worse, scientists are reporting. View More (2010-03-04)
2007 ozone hole 'smaller than usual'
The ozone hole over Antarctica has shrunk 30 percent as compared to last year's record size. According to measurements made by ESA's Envisat satellite, this year's ozone loss peaked at 27.7 million tonnes, compared to the 2006 record ozone loss of 40 million tonnes. View More (2007-10-04)
Columbia engineering study links ozone hole to climate change all the way to the equator
In a study to be published in the April 21st issue of Science magazine, researchers at Columbia University's School of Engineering and Applied Science report their findings that the ozone hole, which is located over the South Pole, has affected the entire circulation of the Southern Hemisphere all the way to the equator.

Record cold winter may increase ozone hole over North Europe
European scientists confirmed that Arctic high atmosphere is reaching the lowest ever temperatures this winter, warning that destruction of the protective ozone layer is substantially increased under very cold conditions. First signs of ozone loss have already been detected. The ozone layer is located in the so called stratosphere, the lowest layer of the atmosphere, at an altitude of... View More (2005-01-31)
NASA Pinpoints Causes of 2011 Arctic Ozone Hole
A combination of extreme cold temperatures, man-made chemicals and a stagnant atmosphere were behind what became known as the Arctic ozone hole of 2011, a new NASA study finds. View More (2013-03-12)
NASA keeps eye on ozone layer amid Montreal Protocol's success
NASA scientists will join researchers from around the world to celebrate the 20th anniversary of the Montreal Protocol, an international treaty designed to reduce the hole in Earth's protective ozone layer. View More (2007-09-14)
Ozone hole recovery may reshape southern hemisphere climate change
A full recovery of the stratospheric ozone hole could modify climate change in the Southern Hemisphere and even amplify Antarctic warming, according to scientists from the University of Colorado at Boulder, the National Oceanic and Atmospheric Administration and NASA. View More (2008-04-25)
