While significant gaps remain in our total knowledge of the extent of carbon dioxide’s sources, such as fires, volcanic activity and the respiration of living organisms, and its natural sinks, such…

The growth in China's carbon dioxide (CO2) emissions is far outpacing previous estimates, making the goal of stabilizing atmospheric greenhouse gases much more difficult, according to a new analysis…

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…
