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)
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... view more... (2005-01-31)
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... view more...

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... view more... (2004-06-25)
NOAA study shows nitrous oxide now top ozone-depleting emission
Nitrous oxide has now become the largest ozone-depleting substance emitted through human activities, and is expected to remain the largest throughout the 21st century, NOAA scientists say in a new study. view more (2009-08-28)
Volcanic aerosol clouds and gases lead to ozone destruction
Volcanic eruptions destroy ozone and create 'mini-ozone holes', according to two new studies by researchers at the Universities of Cambridge and Oxford. view more (2006-11-09)
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... view more... (2001-05-15)
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... view more... (2002-02-06)
Microbes use sunscreens too
Microbes can withstand extreme levels of atmospheric ultraviolet light (UV) by producing their own sunscreens. Unlike humans, some bugs may even be able to survive without any help from the ozone layer scientists heard today (Thursday 19 September) at the Society for General Microbiology autumn meeting at Loughborough University. "A group of... view more... (2002-08-28)
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)
Inside the Ozone Layer
A new atmospheric model is able to quantify man-made versus naturally occurring damage to the stratosphere with an eye toward repairing the diminishing ozone layer that is located within the stratosphere. view more (2006-02-24)
Beyond CO2: Study reveals growing importance of HFCs in climate warming
Some of the substances that are helping to avert the destruction of the ozone layer could increasingly contribute to climate warming. view more (2009-06-23)
Underground Nuclear Explosions Deteriorate The Ozone Layer
Russian scientists have found one more cause of depletion of the ozone layer. They think that abyssal gases can go to the surface and reach stratosphere, deteriorating the ozone shield. Underground nuclear explosions enforce this process. A geologist Boris Golubov of the Institute of Geosphere Dynamics RAS and a climatologist Grigoriy Kruchenitsky... view more... (2002-08-16)
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)
Rocket launches may need regulation to prevent ozone depletion, says study
The global market for rocket launches may require more stringent regulation in order to prevent significant damage to Earth's stratospheric ozone layer in the decades to come, according to a new study by researchers in California and Colorado. view more (2009-04-01)
Climate change and atmospheric circulation will make for uneven ozone recovery
Earth's ozone layer should eventually recover from the unintended destruction brought on by the use of chlorofluorocarbons (CFCs) and similar ozone-depleting chemicals in the 20th century. view more (2009-04-13)
Ozone layer decline leveling off, according to new study
A new global study involving long-term data from satellites and ground stations indicates Earth's ozone layer, while still severely depleted following decades of thinning from industrial chemicals in the atmosphere, is no longer in decline. view more (2005-08-30)
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)
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)
Ozone recovering, but unlikely to stabilize at pre-1980 levels, says study
While Earth's ozone layer is slowly being replenished following an international 1987 agreement banning CFCs, the recovery is occurring in a changing atmosphere and is unlikely to stabilize at pre-1980 levels. view more (2006-05-04)
