Rising surface ozone reduces plant growth and adds to global warming
Scientists from three leading UK research institutes have today released new findings that could have major implications for food production and global warming in the 21st century. view more (2007-07-26)
Ozone layer depletion levelling off
By merging more than a decade of atmospheric data from European satellites, scientists have compiled a homogeneous long-term ozone record that allows them to monitor total ozone trends on a global scale - and the findings look promising. view more (2009-09-22)
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)
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)
Gender may play role in recovery from pneumonia after ozone exposure
Does air pollution have a bigger effect on the immune system of females than males? It did among mice exposed to ozone -- a major component in air pollution that is known to negatively affect lung function -- and then infected with pneumonia, as significantly more females died from the infection than males. view more (2007-06-26)
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)
Study finds no safe level for ozone
Even at very low levels, ozone-the principal ingredient in smog-increases the risk of premature death, according to a nationwide study to be published in the April edition of the journal Environmental Health Perspectives. view more (2006-02-17)
Key molecule discovered in Venus's atmosphere
Venus Express has detected the molecule hydroxyl on another planet for the first time. This detection gives scientists an important new tool to unlock the workings of Venus's dense atmosphere. view more (2008-05-16)
Ozone levels drop when hurricanes are strengthening
Scientists are continually exploring different aspects of hurricanes to increase the understanding of how they behave. Recently, NASA-funded scientists from Florida State University looked at ozone around hurricanes and found that ozone levels drop as a hurricane is intensifying. view more (2005-06-08)
Antarctic plants repair themselves
Dutch researchers funded by NWO have studied the effects of the hole in the ozone layer on the vegetation in Antarctica. The repair mechanisms of lichens and mosses appear to be effective even at low temperatures. Nevertheless, the ecology of the Antarctic is still under threat. The rise in temperature caused by the greenhouse effect is doing... view more... (2001-11-26)
Will an ozone hole develop over the Arctic? A press briefing at the research site
The Theseo presentation will mark the beginning of a decisive period in the development of the Arctic stratosphere. Over the last ten years or so, cold winters have been a prerequisite for maximum ozone depletion, and scientists now understand the chemical processes in the stratosphere that cause the phenomenon. It has been very cold during... view more... (2000-01-21)
Ozone and UV over Europe: no sign of improvement
"The occurrence of ozone mini-holes over Europe increases and any ozone layer recovery could only become measurable around 2010 at the earliest" concludes an assessment report, released today, on European research in the stratosphere. The report concerns loss of ozone, increases in ultraviolet radiation as well as the impact of aircraft... view more... (2002-01-21)
Mountainous plateau creates ozone 'halo' around Tibet
Not only is the air around the world's highest mountains thin, but it's thick with ozone, says a new study from University of Toronto researchers. view more (2005-12-08)
NASA Study Links "Smog" to Arctic Warming
NASA scientists have found that a major form of global air pollution involved in summertime "smog" has also played a significant role in warming the Arctic. view more (2006-03-15)
Winds trigger increases in ozone destroying gases in upper stratosphere
A surprising new University of Colorado at Boulder study indicates winds circling high above the far Northern Hemisphere have a much greater impact on upper stratospheric ozone levels than scientists had thought. view more (2006-09-29)
NASA airborne expedition chases climate, ozone questions
NASA's Tropical Composition, Cloud and Climate Coupling (TC4) field campaign will begin this summer in San Jose, Costa Rica, with an investigation into how chemical compounds in the air are transported vertically into the stratosphere and how that transport affects cloud formation and climate. view more (2007-06-28)
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)
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)
By ice floe to the North Pole
At the end of August, an unusual expedition under Russian leadership will leave for the Arctic Ocean. One of the participants is Jürgen Graeser of the Alfred Wegener Institute for Polar and Marine Research, one of the research centres of the Helmholtz Association. view more (2007-07-23)
Outdoor Team Sports In High-Ozone Environments Could Triple Asthma Risk In Children (p 386)
A US study in this week's issue of THE LANCET highlights how children playing outdoor team sports in areas of high ozone concentration could be three times more likely to develop asthma than children who do not take part in sporting activities. Asthma is the most common chronic disease of childhood; its prevalence and incidence have been... view more... (2002-01-30)
