New isotope cluster could lead to better understanding of atmospheric carbon dioxide
A team of researchers has discovered an unexpected concentration of a certain isotopic molecule in parts of the stratosphere that could have implications for understanding the carbon cycle and its response to climate change. view more (2009-07-15)
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)
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)
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)
Cyclones spurt water into the stratosphere, feeding global warming
Scientists at Harvard University have found that tropical cyclones readily inject ice far into the stratosphere, possibly feeding global warming. view more (2009-04-21)
Tibet Provides Passage for Chemicals to Reach the Stratosphere
NASA and university researchers have found that thunderstorms over Tibet provide a main pathway for water vapor and chemicals to travel from the lower atmosphere, where human activity directly affects atmospheric composition, into the stratosphere, where the protective ozone layer resides. view more (2006-05-10)
SARS From Outer Space? (p 1832)
An alternative theory to the origin of severe acute respiratory syndrome (SARS) is proposed by scientists in a letter in this week's issue of THE LANCET--that the disease may have originated in outer space. Chandra Wickramasinghe from Cardiff University, UK, and colleagues describe how around a tonne of bacteria is deposited on the earth every... view more... (2003-05-21)
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)
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...

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)
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)
Global warming may delay recovery of stratospheric ozone
Increasing greenhouse gases could delay, or even postpone indefinitely the recovery of stratospheric ozone in some regions of the Earth, a new study suggests. This change might take a toll on public health. view more (2009-02-05)
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)
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 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)
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)
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)
Stratospheric injections could help cool Earth, computer model shows
A two-pronged approach to stabilizing climate, with cuts in greenhouse gas emissions as well as injections of climate-cooling sulfates, could prove more effective than either approach used separately. view more (2006-09-15)
Stratospheric ozone chemistry plays an important role for atmospheric airflow patterns
Interactions between the stratospheric ozone chemistry and atmospheric air flow lead to significant changes of airflow patterns from the ground up to the stratosphere. view more (2008-03-10)
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)
