ESA to select new Earth Explorer missions
An important milestone for ESA's Living Planet Programme is to be reached this spring when it will be decided which of the six candidate Earth Explorer missions are to be selected for development. Before decisions are taken, the user community is invited to express their views at the Earth Explorer... view more (2004-02-05)

Computer models show major climate shift as a result of closing ozone hole
A new study led by Columbia University researchers has found that the closing of the ozone hole, which is projected to occur sometime in the second half of the 21st century, may significantly affect climate change in the Southern Hemisphere, and therefore, the global climate.   view more (2008-06-13)

High-Flying Balloons Begin Tracking Emerging Hurricanes
In a unique collaboration, U.S. and French researchers are launching large, specialized balloons into the stratosphere to drop nearly 300 instrument packages over wide swaths of Africa and the Atlantic Ocean.   view more (2006-09-01)

Field Project Seeks Clues to Climate Change in Remote Atmospheric Region
Scientists are deploying an advanced research aircraft to study a region of the atmosphere that influences climate change by affecting the amount of solar heat that reaches Earth's surface.   view more (2008-06-13)

Ozone hole recovery may reshape southern hemisphere climate change
A full recovery of the stratospheric ozone hole could modify climate change in the Southern Hemisphere and even amplify Antarctic warming, according to scientists from the University of Colorado at Boulder, the National Oceanic and Atmospheric Administration and NASA.   view more (2008-04-25)

The highest human freefall from the stratosphere
A team of researchers from the Universitat Autònoma de Barcelona, in coordination with the Instituto Nacional de Técnica Aerospacial Esteban Terradas (INTA – Esteban Terradas National Institute of Aerospace Technology), is preparing for a person to jump from an altitude of... view more (2002-04-15)

Ozone recovering, but unlikely to stabilize at pre-1980 levels, says study
While Earth's ozone layer is slowly being replenished following an international 1987 agreement banning CFCs, the recovery is occurring in a changing atmosphere and is unlikely to stabilize at pre-1980 levels.   view more (2006-05-04)

The tropics may be expanding
Atmospheric temperature measurements by U.S. weather satellites indicate Earth's hot, tropical zone has expanded farther from the equator since 1979, says a study by scientists from the University of Utah and University of Washington.   view more (2006-05-26)

Antarctic forecast: premature break-up of ozone hole this week
Based on satellite data from the European Space Agency, the national meteorological centre of the Netherlands predicts the Antarctic ozone hole will break apart this week, months earlier than usual. A scientist at the Royal Netherlands Meteorological Institute (KNMI) adds that the depth of the... view more (2002-09-23)

Advanced Aircraft to Probe Hazardous Atmospheric Whirlwinds
The nation's newest and most advanced research aircraft will participate in its first major mission March 1 through April 30, when it will study a severe type of atmospheric turbulence that forms near mountains and endangers airplanes.   view more (2006-03-02)

Changing jet streams may alter paths of storms and hurricanes
The Earth's jet streams, the high-altitude bands of fast winds that strongly influence the paths of storms and other weather systems, are shifting-possibly in response to global warming.   view more (2008-04-17)

Earth, Wind and Volcanoes - Disaster Science
Ash with Altitude "Volcanic ash, ejected into the stratosphere and spread horizontally by the winds, can cause serious damage to aircraft engines and sensors," says Dr Charles Sprinkle of the US National Weather Service. Modern jet engines operate at such high temperatures that volcanic... view more (1999-10-26)

Stardust comet dust resembles asteroid materials
Contrary to expectations for a small icy body, much of the comet dust returned by the Stardust mission formed very close to the young sun and was altered from the solar system's early materials.   view more (2008-01-25)

Burning asteroids may play 'more important climate role than previously recognized'
Dust from asteroids entering the atmosphere may influence Earth's weather more than previously believed, researchers have found.   view more (2005-08-26)

Gone With the Wind? Over A Hundred Scientists Take To The Skies To Track Global Air Pollution
This morning a team of forty scientists from seven UK universities will travel to the Azores to join hundreds more in the largest international atmospheric field campaign of its type ever attempted. The exciting mission will track and investigate a mass of polluted air as it leaves the United... view more (2004-07-08)

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... view more (2007-06-26)

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)

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)

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)

Geoengineering could slow down the global water cycle
As fossil fuel emissions continue to climb, reducing the amount of sunlight hitting the Earth would definitely have a cooling effect on surface temperatures.   view more (2008-05-28)

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)

NASA sees into the eye of a monster storm on Saturn
NASA's Cassini spacecraft has seen something never before seen on another planet - a hurricane-like storm at Saturn's south pole with a well-developed eye, ringed by towering clouds.   view more (2006-11-10)

Scientists use meteors to investigate climate change and giant waves at the 'edge of space'
A new research radar based in Antarctica is giving scientists the chance to study the highest layer of the earth's atmosphere at the very edge of space.   view more (2005-05-23)

Low levels of contamination also influence mortality rate
Navarre doctor Rosa Mar'­a Al'¡s Brun has shown, in her PhD thesis defended at the Public University of Navarre, that, despite contamination rates in Pamplona being very low, these still have an influence on death rates.   view more (2004-08-20)

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... view more (2000-12-15)
