University of Toronto study shows climate change will lead to less ultraviolet radiation over northern high latitudes
Physicists at the University of Toronto have discovered that changes in the Earth's ozone layer due to climate change will reduce the amount of ultraviolet (UV) radiation in northern high latitude regions such as Siberia, Scandinavia and northern Canada. view more (2009-09-16)
New window into ancient ozone holes
British researchers have hit on a clever way to search for ancient ozone holes and their relationship to mass extinctions: measure the remains of ultraviolet-B absorbing pigments ancient plants left in their fossilized spores and pollen. view more (2005-08-10)
Houseplants cut indoor ozone
Ozone, the main component of air pollution, or smog, is a highly reactive, colorless gas formed when oxygen reacts with other chemicals. view more (2009-09-09)
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)
Research finds new cause of ozone wheezing and potential treatments
Researchers at the National Institute of Environmental Health Sciences (NIEHS), part of the National Institutes of Health, and Duke University have discovered a cause of airway irritation and wheezing after exposure to ozone, a common urban air pollutant. view more (2009-02-04)
Long-Term ozone measurements from Space assured
The EUMETSAT Polar System, and the ESA METOP-1 Programme together form a co-operative venture between the two organisations, and lead to the launch of the first METOP satellite in mid-2003. The system provides operational meteorological data from polar orbiting satellites, to complement and complete an international system of polar satellites... view more... (2000-03-05)
Indoor air purifiers that produce even small amounts of ozone may be risky for health
In a small, poorly ventilated room, an indoor air purifier that produces even a few milligrams of ozone per hour can create an ozone level that exceeds public health standards. view more (2006-05-10)
Ozone shuts down early immune response in lungs and body
As policy makers debate what levels of ozone in the air are safe for humans to breathe, studies in mice are revealing that the inhaled pollutant impairs the body's first line of defense, making it more susceptible to subsequent foreign invaders, such as bacteria. view more (2007-10-01)
Fires in Alaska and Canada caused sharp increase in Houston's ozone level
Forest fires that ravaged parts of eastern Alaska and western Canada in 2004 exacerbated the already-high levels of ozone pollution in Houston, Texas, some 5,000 kilometers [3,000 miles] away. view more (2006-09-25)
ESA finds a black-hole flywheel in the Milky Way
Far away among the stars, in the Ara constellation of the southern sky, a small black hole is whirling space around it. If you tried to stay still in its vicinity, you couldn`t. You`d be dragged around at high speed as if you were riding on a giant flywheel. In reality, gas falling into the black hole is whirled in that way. It radiates energy,... view more... (2002-04-26)
Wildfires Cause Ozone Pollution to Violate Health Standards, New Study Shows
Wildfires can boost ozone pollution to levels that violate U.S. health standards, a new study concludes. view more (2008-10-10)

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)
Study: Perception of hole size influenced by performance
Golfers who play well are more likely to see the hole as larger than their poor-playing counterparts, according to a Purdue University researcher. view more (2008-07-08)
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)
UCI scientists find chlorine may contribute to ozone formation
Standard methods of predicting air pollution don't take atmospheric chlorine into account, but the chemical could be responsible for 10 percent or more of daily ozone production in local air, research at UC Irvine has found. view more (2006-06-14)
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)
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)
European satellites provide new insight into ozone-depleting chemical species
Using data from the MIPAS and GOME-2 satellite instruments, scientists have for the first time detected important bromine species in the atmosphere. view more (2009-02-26)
Setting stars reveal planetary secrets
Watching the stars set from the surface of the Earth may be a romantic pastime but when a spacecraft does it from orbit, it can reveal hidden details about a planet's atmosphere. view more (2007-11-06)
