Methyl bromide alternatives indicated for North Carolina tomato production
Methyl bromide (MeBr) is a highly effective broad-spectrum fumigant used extensively in U.S. agriculture to control a wide variety of pests. Under the Montreal protocol of 1991, however, MeBr was defined as one of the chemicals that contributed to the depletion of the stratospheric ozone layer, resulting in an incremental reduction in the amount... view more...

Aerosols may drive a significant portion of arctic warming
Though greenhouse gases are invariably at the center of discussions about global climate change, new NASA research suggests that much of the atmospheric warming observed in the Arctic since 1976 may be due to changes in tiny airborne particles called aerosols. view more (2009-04-09)
The Rise of Oxygen Caused Earth's Earliest Ice Age
Geologists may have uncovered the answer to an age-old question - an ice-age-old question, that is. view more (2009-05-07)

Air pollution linked to cardiovascular risk indices in healthy young adults
Researchers in Taiwan have demonstrated for the first time that urban air pollution simultaneously affects key indicators of cardiovascular risk in young adults: inflammation, oxidative stress, coagulation and autonomic dysfunction. view more (2007-08-15)
Small fluctuations in solar activity, large influence on the climate
Our sun does not radiate evenly. The best known example of radiation fluctuations is the famous 11-year cycle of sun spots. Nobody denies its influence on the natural climate variability, but climate models have, to-date, not been able to satisfactorily reconstruct its impact on climate activity. view more (2009-08-28)
UT Southwestern allergist offers coping strategies
The good news for allergy sufferers is that springtime mountain cedars and tree pollens have generally subsided. The bad news: It's summertime. view more (2006-06-14)
Pollution, everyday allergens, may be sources of laryngitis
Everyday exposure to environmental tobacco smoke, allergens, and air pollution may be the root of chronic cases of laryngitis, says new research presented at the 2008 American Academy of Otolaryngology - Head and Neck Surgery Foundation (AAO-HNSF) Annual Meeting & OTO EXPO in Chicago, IL. view more (2008-09-22)
Launch of weather satellite CD-ROM
The CD-ROM has been produced on behalf of the Coordination Group for Meteorological Satellites Meteorological Satellites (CGMS). Its production follows nearly 40 years of data from space, helping improve meteorology, monitoring of the climate, the state of the oceans, land surfaces and planetary atmosphere. view more (1999-08-17)
Termite insecticide a potent greenhouse gas
An insecticide used to fumigate termite-infested buildings is a strong greenhouse gas that lives in the atmosphere nearly 10 times longer than previously thought, UC Irvine research has found. view more (2009-01-22)
The greenhouse gas that saved the world
When Planet Earth was just cooling down from its fiery creation, the sun was faint and young. So faint that it should not have been able to keep the oceans of earth from freezing. But fortunately for the creation of life, water was kept liquid on our young planet. view more (2009-08-18)
Satellites confirm half-century of West Antarctic warming
The Antarctic Peninsula juts into the Southern Ocean, reaching farther north than any other part of the continent. The southernmost reach of global warming was believed to be limited to this narrow strip of land, while the rest of the continent was presumed to be cooling or stable. view more (2009-01-23)
Termite Killer Lingers as a Potent Greenhouse Gas
Sulfuryl fluoride (SO2F2), a gas commonly used to rid buildings of termites and other pests, is a greenhouse gas that remains in the atmosphere about 36 years, six to 10 times longer than previously thought, according to a research team led by Jens Mühle, an atmospheric chemist at Scripps Institution of Oceanography, UC San Diego. view more (2009-03-11)
A bubbling ball of gas
The Sun is a bubbling mass. Packages of gas rise and sink, lending the sun its grainy surface structure, its granulation. Dark spots appear and disappear, clouds of matter dart up - and behind the whole thing are the magnetic fields, the engines of it all. view more (2009-11-12)
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)
Polar clouds take a 'bite' out of meteoric iron
Polar clouds are known to play a major role in the destruction of Earth's protective ozone layer, creating the springtime 'ozone hole' above Antarctica. Now, scientists have found that polar clouds also play a significant role in removing meteoric iron from Earth's atmosphere. Polar clouds have been widely studied in recent years, because of their... view more... (2004-04-14)
New process offers slick solution to tyre waste
With fossil fuels running out, the oil and gas tied up in the millions of waste tyres discarded each year has been targeted as a possible fuel source for decades. Tyres can yield up to 60% of their weight as fuel oil, but the relatively low price of refined crude means it makes little economic sense to use tyre-derived products. Dr Williams... view more...

Air Quality Forecasts for China
With less than a month remaining before the Beijing Olympics, Chinese officials have introduced a series of measures to improve air quality for the Games. A new tool has been installed in the capital city to allow the Chinese to monitor the effectiveness of these efforts. view more (2008-07-24)
Mercury in atmosphere could be washed out more easily than earlier believed
Scientists for years have been at a loss to explain unexpectedly high levels of mercury in fish swimming the rivers and streams of areas like eastern Oregon, far away from industrial sources of mercury pollution such as coal-fired power plants. view more (2005-12-08)
Washington Getting a Summertime Air Quality Exam
Summer in the city can often mean sweltering "bad air days" that threaten the health of the elderly, children and those with respiratory problems. This summer the nation's capitol has been no stranger to such severe air-quality alerts. view more (2006-08-07)
