There's no dispute that natural variations of atmospheric air flow patterns have played an important role in climate change in the last decades. Basic knowledge of how and why it happens is necessary…

Scientists have solved a 40-year-old puzzle by identifying the origin of the intense radio waves in the Earth's upper atmosphere that control the dynamics of the Van Allen radiation belts — belts…

A destructive spring freeze that chilled the eastern United States almost a year ago illustrates the threat a warming climate poses to plants and crops, according to a paper just published in the…

Modern diesel cars are quieter than their predecessors but also release considerably fewer exhaust fumes into the atmosphere. But the real culprit in diesel are heavy-duty, construction and off-road…

Research from ancient sediment cores indicates that a warming climate could make the world’s arctic tundra far more susceptible to fires than previously thought. The findings are important given the…

Widespread damage to plants from a sudden freeze that occurred across the Eastern United States from 5 April to 9 April 2007 was made worse because it had been preceded by two weeks of unusual warmth…

Brent Christner, LSU professor of biological sciences, in partnership with colleagues in Montana and France, recently found evidence that rain-making bacteria are widely distributed in the atmosphere…

Researchers writing in PMC Physics B have found that the rate at which electrons lose energy to carbon monoxide is greater than that to carbon dioxide at higher levels in the atmospheres of both Mars…

A discovery in molecular chemistry may help remove a barrier to widespread use of diesel and other fuel-efficient "lean burn" vehicle engines. Researchers at the Department of Energy's Pacific…

Research carried out by scientists from Earthwatch, the international environmental charity, has reinforced the urgent need to protect Europe’s remaining peat bogs. Dubbed the ‘rainforests of Europe…
