  • NASA Chases Climate Change Clues Into The Stratosphere

    Starting this month, NASA will send a remotely piloted research aircraft as high as 65,000 feet over the tropical Pacific Ocean to probe unexplored regions of the upper atmosphere for answers to how a warming climate is changing Earth. The first flights of the Airborne Tropical Tropopause Experiment (ATTREX), a multi-year airborne science campaign with a heavily instrumented Global Hawk aircraft, ...

  • Stratospheric water vapor is a global warming wild card

    A 10 percent drop in water vapor ten miles above Earth’s surface has had a big impact on global warming, say researchers in a study published online January 28 in the journal Science. The findings might help explain why global surface temperatures have not risen as fast in the last ten years as they did in the 1980s and 1990s. Observations from satellites and balloons show that stratospheric ...

  • Ozone layer recovery may be delayed by greenhouse gas emissions

    The ozone layer in the stratosphere protects life on Earth from harmful radiation, but emissions from human activity have damaged this defence. A new study suggests that ozone recovery could be delayed, or even postponed indefinitely for some regions, by the impact of increasing amounts of greenhouse gases (GHGs) in the atmosphere. Although ozone at ground level is hazardous to health, ozone in ...

  • An instrument from Environnement S.A will measure volcano ashes

    In partnership with the environment and space physics and chemistry laboratory at orleans and CNES (National Space Research Centre), we have started the development ofa ‘LOAC’ measurement system, that will count and size grade aerosols, for balloon-carried stratospheric measurement applications. The first flight of the LOAC was organised by the CNES, from the ESRANGE/Kiruna base ...

  • The ozone hole of 2008 is larger than in 2007

    “After decades of chemical attack, it may take another 50 years or so for the ozone layer to recover fully. As the Montreal Protocol has taught us, when we degrade our environment too far, nursing it back to health tends to be a long journey, not a quick fix”, said Ban Ki-moon, Secretary-General of the United Nations, on the occasion of the International Day for the Preservation of Ozone Layer ...

  • Climate change impacts linked to ozone depletion

    "A warming world with violent storms holds many unpleasant surprises" said Durwood Zaelke, President of the Institute for Governance and Sustainable Development (IGSD). "Recent research now suggests that this may include damage to the protective ozone shield, which protects us from harmful ultraviolet radiation that causes skin cancer, cataracts, suppresses the human immune system, and damages ...

  • Ozone hole grows but is below 2006 record

    Scientists from the German Aerospace Centre (DLR) have discovered that the ozone hole over Antarctica has expanded this year against what it was in 2007, but is smaller than what it was in 2006. The ozone is a protective atmospheric layer protecting Earth from harmful ultraviolet rays. Failure to shield the planet can trigger a multitude of health ailments in people and harm biodiversity. While ...

  • 2008 ozone hole larger than last year - ESA

    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. Ozone is a protective atmospheric layer found in about 25 kilometres altitude that acts as a sunlight filter shielding life on Earth from harmful ultraviolet rays, which can increase the risk of skin cancer and cataracts and harm marine life.  This ...

  • Cassini Spacecraft and Ground Telescope See Violent Saturn Storm

    NASA's Cassini spacecraft and a European Southern Observatory ground-based telescope tracked the growth of a giant early-spring storm in Saturn's northern hemisphere so powerful it stretches around the entire planet. The rare storm has been wreaking havoc for months and shot plumes of gas high into the ...

  • NASA Finds Sea Ice Decline Driving Rise in Arctic Air Pollutants

    Drastic reductions in Arctic sea ice in the last decade may be intensifying the chemical release of bromine into the atmosphere, resulting in ground-level ozone depletion and the deposit of toxic mercury in the Arctic, according to a new NASA-led study. The connection between changes in the Arctic Ocean's ice cover and bromine chemical processes is determined by the interaction between the salt ...

  • 2013 Ozone2Climate Technology Roadshow Highlights HCFC Alternatives to Safeguard Ozone Layer

    A roadshow organized by UNEP OzonAction and the China Refrigeration and Air-Conditioning Association (CRAA) has got underway in Shanghai to highlight safe alternatives to hydrochlorofluorocarbons (HCFCs), which damage the stratospheric ozone layer, in refrigeration and air conditioning (RAC) technologies. Many ozone and climate-friendly alternative technologies to HCFC-based equipment with ...

  • Nitrous oxide is now top ozone-layer damaging emission

    According to new research, emissions of anthropogenic nitrous oxide (N2O) are now causing more damage to the ozone layer than those of any controlled ozone depleting substance and this is projected to remain the case for the rest of this century. The study suggests that limiting N2O emissions could help both the recovery of the ozone layer and tackle climate change. Many ozone-depleting ...

  • Global warming caused by CFCs, not carbon dioxide, study says

    Chlorofluorocarbons (CFCs) are to blame for global warming since the 1970s and not carbon dioxide, according to new research from the University of Waterloo published in the International Journal of Modern Physics B this week. CFCs are already known to deplete ozone, but in-depth statistical analysis now shows that CFCs are also the key driver in global climate change, rather than carbon ...

  • Are sunspots prime suspects in global warming?

    (AXcess News) - It's a modern-day climate scuffle William Herschel would recognize. He should. He helped trigger it. In 1801, the eminent British astron­­omer reported that when sunspots dotted the sun's surface, grain prices fell. When sunspots waned, prices rose. He suggested that shifts in grain prices were a stand-in for shifts in climate. Large numbers of sunspots led to a ...

  • Antarctic Ocean Losing Ability to Absorb Carbon Dioxide

    Norwich, UK - Recent climate change brought on by human activities has weakened one the Earth's natural defenses against global warming. Atmospheric carbon dioxide is not being absorbed by the Southern Ocean as quickly as it once was, an international research team has found. Scientists have observed the first evidence that the Southern Ocean’s ability to absorb the major greenhouse gas carbon ...
