Marine Algae A Weapon Against Global Warming?
"Parforce" an EU-funded research project has discovered a new link between marine algae and climate change. Researchers working on the project found out that iodine vapours, released from algae or plankton, condense over oceans to form aerosols . These aerosols, which tend to counter "global... view more (2002-07-18)

NASA study improves ability to predict aerosols' effect on cloud cover
Using a novel theoretical approach, researchers from NASA and other institutions have identified the common thread that determines how aerosols from human activity, like the particles from burning of vegetation and forests, influence cloud cover and ultimately affect climate.   view more (2008-08-15)

Electric sand findings could lead to better climate models
Wind isn't acting alone in the geological process behind erosion, sand dunes and airborne dust particles called aerosols.   view more (2008-01-08)

Record air pollution above the Arctic
Last week Scientists of the Alfred Wegener Institute for Polar and Marine Research observed the highest air pollution on record since measurements began in Ny-Ã-lesund on Svalbard. Monitoring instruments displayed significantly increased aerosol concentrations compared to those generally found.   view more (2006-05-11)

Laboratory scientists study soot in megacity pollution
A team of Los Alamos scientists recently returned from a month-long data-gathering trip to Mexico City as part of an international, multi-agency environmental science collaboration.   view more (2006-05-09)

Detecting secondary aerosols
EUREKA project E! 2507 EUROENVIRON COPAP has developed a new detection device that will aid research into global climate change, environmental studies, life-science research and environmental monitoring and improve understanding on aerosols.   view more (2005-02-03)

Central American fires impact US air quality and climate
Scientists using NASA satellites and computer models have shown that pollutants from Central American biomass burning can influence air quality and climate in the United States.   view more (2006-10-11)

Airborne dust causes ripple effect on climate far away
When a small pebble drops into a serene pool of water, it causes a ripple in the water in every direction, even disturbing distant still waters.   view more (2007-01-30)

Seeing clearly despite the clouds
Satellites taking atmospheric measurements might now be able to see blue skies as clearly as optimists do. Researchers have found a way to reduce cloud-induced glare when satellites measure blue skies on cloudy days, by as much as ten-fold in some cases.   view more (2008-05-21)

Global 'sunscreen' has likely thinned, report NASA scientists
A new NASA study has found that an important counter-balance to the warming of our planet by greenhouse gases - sunlight blocked by dust, pollution and other aerosol particles - appears to have lost ground.   view more (2007-03-19)

NASA probes the sources of the world's tiny pollutants
Pinpointing pollutant sources is an important part of the ongoing battle to improve air quality and to understand its impact on climate. Scientists using NASA data recently tracked the path and distribution of aerosols — tiny particles suspended in the air — to link their region of... view more (2007-01-31)

Scientists want to solve puzzle of excess water vapor near cirrus clouds
A number of researchers in recent years have reported perplexing findings of water vapor at concentrations as much as twice what they should be in and around cirrus clouds high in the atmosphere, a finding that could alter some conclusions about climate change.   view more (2006-12-01)

Tiny airborne particles are a major cause of climate change
A scientist at the Weizmann Institute of Science and his colleagues caused a storm in the atmospheric community when they suggested a few years back that tiny airborne particles, known as aerosols, may be one of the main culprits causing climate change - having, on a local scale, an even greater... view more (2006-07-19)

Invisible gases form most organic haze in urban, rural areas
A new study involving the University of Colorado at Boulder shows that invisible, reactive gases hovering over Earth's surface, not direct emissions of particulates, form the bulk of organic haze in both urban and rural areas around the world.   view more (2007-07-10)

Seismic images show dinosaur-killing meteor made bigger splash
The most detailed three-dimensional seismic images yet of the Chicxulub crater, a mostly submerged and buried impact crater on the Mexico coast, may modify a theory explaining the extinction of 70 percent of life on Earth 65 million years ago.   view more (2008-01-24)

Volcanoes helped slow ocean warming trend, researchers find
Ocean temperatures might have risen even higher during the last century if it weren't for volcanoes that spewed ashes and aerosols into the upper atmosphere, researchers have found. The eruptions also offset a large percentage of sea level rise caused by human activity.   view more (2006-02-10)

New satellite set to collect most-detailed data yet about atmospheric particles
A new satellite that last week began gathering data from the Earth's atmosphere could be a key tool in unraveling just how much effect the reflectivity of clouds and tiny particles called aerosols are having on the planet's changing climate.   view more (2006-06-13)

NASA satellite measures pollution from east Asia to North America
In a new NASA study, researchers taking advantage of improvements in satellite sensor capabilities offer the first measurement-based estimate of the amount of pollution from East Asian forest fires, urban exhaust, and industrial production that makes its way to western North America.   view more (2008-03-18)

Reducing air pollution could increase rice harvests in India
New research from the University of California indicates that reductions of human-generated air pollution could create unexpected agricultural benefits in one of the world's poorest regions. These new findings will be published online the week of Dec. 4 in the journal Proceedings of the National... view more (2006-12-05)

Tiny dust particles from Asian deserts common over western United States
It has been a decade since University of Washington scientists first pinpointed specific instances of air pollution, including Gobi Desert dust, traversing the Pacific Ocean and adding to the mix of atmospheric pollution already present along the West Coast of North America.   view more (2007-12-13)

Gassed by gannets!
This is one of the subjects being investigated in the GANE (Global Atmospheric Nitrogen Enrichment) research initiative funded by NERC. The first meeting of the principal investigators will be on Thursday, 9th March, when they will share information on progress of the various projects that form the... view more (2000-03-08)

Rats on a road trip reveal pollution-heart disease risk
Rats that rode in a truck on the New York State Thruway between Rochester and Buffalo and were exposed to the same highway pollution that motorists encounter, showed a drop in heart rate and effects on the autonomic nervous system   view more (2007-02-01)

Scientists to Assess Beijing Olympics Air Pollution Control Efforts
As the Summer Olympics in Beijing kicks off this week, the event is giving scientists a once-in-a-lifetime opportunity to observe how the atmosphere responds when a heavily populated region substantially curbs everyday industrial emissions.   view more (2008-08-11)

Researchers to Scrutinize Megacity Pollution During Mexico City Field Campaign
A team of researchers from the National Center for Atmospheric Research (NCAR) and other institutions is heading to Mexico City to participate in one of the most complex field campaigns ever undertaken in atmospheric chemistry.   view more (2006-03-03)

Are aerosols reducing coastal drizzle and increasing cloud cover?
Scientists sponsored by the Department of Energy are conducting a six-month atmospheric research campaign at the Point Reyes National Seashore, in Marin County, California. The experiment's goal is to help researchers understand how aerosols -small particles such as soot, dust and smoke-influence... view more (2005-07-01)
