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)
Crab claws pack strengthening bromide-rich biomaterial
Next time you have an unlucky encounter with a crab's pinchers, consider that the claw tips may be reinforced with bromine-rich biomaterial 1.5 times harder than acrylic glass and extremely fracture resistant, says a University of Oregon scientist. view more (2009-02-26)
Contraceptive pill produced from potato toxin
Dutch researcher Patrick Vronen from Wageningen University has investigated several methods for converting toxins in high-starch potatoes into a raw material for steroid hormones used, for example, in contraceptive pills. The molecular structure of the potato toxin solanidine, which is found in high-starch potatoes, is similar to that of... view more... (2003-06-24)
New clues to ozone depletion
Laerge quantities of ozone-depleting chemicals have been discovered in the Antarctic atmosphere by researchers from the University of Leeds, the University of East Anglia, and the British Antarctic Survey. view more (2007-07-27)
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)
Water detection at Gusev crater described
A large team of NASA scientists, led by earth and planetary scientists at Washington University in St. Louis details the first solid set of evidence for water having existed on Mars at the Gusev crater, exploration site of the rover Spirit. view more (2005-09-08)
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)
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)
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)
New policies needed to combat Global Change, says Commissioner Wallström
Never before have policy makers faced a more challenging task than responding to global change, said EU Environment Commissioner Margot Wallström, in an article in the International Herald Tribune today (http://www.iht.com/articles/125563.html) and in a statement made for the launch of a new book on global change*... view more...

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)
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)
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)
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)
New simulation shows consequences of a world without Earth's natural sunscreen
Nearly two-thirds of Earth's ozone is gone -- not just over the poles, but everywhere. The infamous ozone hole over Antarctica, first discovered in the 1980s, is a year-round fixture, with a twin over the North Pole. The ultraviolet (UV) radiation falling on mid-latitude cities like Washington, D.C., is strong enough to cause sunburn in just five... view more... (2009-03-19)
Satellite sniffs out chemical traces of atmospheric pollution
The recent Hague talks on global warming focused attention on the so-called greenhouse gases in our atmosphere. But these gases are only a part of the story. Mankind generates a wide variety of emissions that are changing the chemistry and composition of our planet~s atmosphere. Satellite monitoring is helping scientists to understand those... view more... (2000-12-15)
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)
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)
World`s Largest Switchboard for Climate Monitoring
Europe`s showpiece in climate monitoring is called Envisat. Fully equipped, the largest, most complex, and most powerful Earth observation satellite of the European Space Agency (ESA) is 25 meters high, ten meters wide and weighs over eight tons, scheduled for launch in the night of 28 February /1st March on an Ariane 5 launcher. Europe`s flying... view more... (2002-02-27)
