Sometimes dry soils yield more clouds
Symposium of the American Meteorological Society in Wageningen (The Netherlands) Cloud formation does not always follow beaten tracks. The formation of low clouds during nice weather conditions will normally take place above moist soils. Under specific atmospheric conditions, which can occur in Europe, drier soils yield more clouds, according to a... view more... (2002-07-12)
Ancient oceans offer new insight into the origins of animal life
Analysis of a rock type found only in the world's oldest oceans has shed new light on how large animals first got a foothold on the Earth. view more (2009-09-10)
Deep-rooted plants have much greater impact on climate than experts thought
Trees, particularly those with deep roots, contribute to the Earth's climate much more than scientists thought, according to a new study by biologists and climatologists from the University of California, Berkeley. view more (2006-01-12)
Recipe for a storm: The ingredients for more powerful Atlantic hurricanes
As the world warms, the interaction between the Atlantic Ocean and atmosphere may be the recipe for stronger, more frequent hurricanes. view more (2007-11-30)
Water found to be main culprit in Argentine ant invasions
According to a study conducted by two biologists at the University of California, San Diego, Argentine ants in Southern California need wet soil to live and breed. view more (2006-03-30)
Greenland ice core analysis shows drastic climate change near end of last ice age
Information gleaned from a Greenland ice core by an international science team shows that two huge Northern Hemisphere temperature spikes prior to the close of the last ice age some 11,500 years ago were tied to fundamental shifts in atmospheric circulation. view more (2008-06-20)
Prehistoric global warming may have contributed to fossil preservation
Prehistoric global warming episodes from massive atmospheric pollution involving carbon dioxide and methane could have created and preserved "mass kills" of wildlife, according to a University of Oregon study presented at the Geological Society of America's annual meeting. view more (2005-10-13)
NASA aircraft captures windy details in hurricane's ups and downs
Researchers employing some of the world's most sophisticated weather research equipment recently captured details on winds and other conditions in a rapidly intensifying hurricane. This data will help to advance the understanding of these complex storms. view more (2006-12-12)
Revised theory suggests carbon dioxide levels already in danger zone
If climate disasters are to be averted, atmospheric carbon dioxide (CO2) must be reduced below the levels that already exist today, according to a study published in Open Atmospheric Science Journal by a group of 10 scientists from the United States, the United Kingdom and France. view more (2008-11-10)
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)
NASA experiment stirs up hope for forecasting deadliest cyclones
NASA satellite data and a new modeling approach could improve weather forecasting and save more lives when future cyclones develop. view more (2009-04-14)
Soil nutrition affects carbon sequestration in forests
On December 11, USDA Forest Service (FS) scientists from the FS Southern Research Station (SRS) unit in Research Triangle Park, NC, along with colleagues from Duke University, published two papers in The Proceedings of the National Academy of Science (PNAS) that provide a more precise understanding of how forests respond to increasing atmospheric... view more...

Chemical Could Revolutionize Polymer Fuel Cells
Heat has always been a problem for fuel cells. There's usually either too much (ceramic fuel cells) for certain portable uses, such as automobiles or electronics, or too little (polymer fuel cells) to be efficient. view more (2005-08-25)
Stratospheric ozone chemistry plays an important role for atmospheric airflow patterns
Interactions between the stratospheric ozone chemistry and atmospheric air flow lead to significant changes of airflow patterns from the ground up to the stratosphere. view more (2008-03-10)
Changes to land cover may enhance global warming in Amazon, reduce it in midlatitudes
New simulations of 21st-century climate show that human-produced changes in land cover could produce additional warming in the Amazon region comparable to that caused by greenhouse gases, while counteracting greenhouse warming by 25% to 50% in some midlatitude areas. view more (2005-12-09)
New clues to ozone depletion
Laerge quantities of ozone-depleting chemicals have been discovered in the Antarctic atmosphere by researchers from the University of Leeds, the University of East Anglia, and the British Antarctic Survey. view more (2007-07-27)
Climate researchers meet to simulate flight operations for storm cloud experiment
Summertime in northern Australia means monsoon storms - and plenty of them. Tall, turbulent clouds associated with these storm systems form rapidly, release their energy in the form of rain, then tail away, leaving in their wake a surplus of moisture to feed the next system. view more (2005-09-14)
Atmospheric Mercury Has Declined -- But Why?
The amount of gaseous mercury in the atmosphere has dropped sharply from its peak in the 1980s and has remained relatively constant since the mid 1990s. This welcome decline may result from control measures undertaken in western Europe and North America, but scientists who have just concluded a study of atmospheric mercury say they cannot... view more...

New model revises estimates of terrestrial carbon dioxide uptake
Researchers at the University of Illinois have developed a new model of global carbon and nitrogen cycling that will fundamentally transform the understanding of how plants and soils interact with a changing atmosphere and climate. view more (2007-12-12)
Ocean growing more acidic faster than once thought
University of Chicago scientists have documented that the ocean is growing more acidic faster than previously thought. In addition, they have found that the increasing acidity correlates with increasing levels of atmospheric carbon dioxide. view more (2008-11-25)
