Higher Water Temperatures and Reduced Ice Cover In the Arctic Ocean
Over the past six weeks, scientists aboard the research vessel "Polarstern" of the Alfred Wegener Institute for Polar and Marine Research have been investigating changes in ocean temperature and sea ice cover in the area of Fram Strait between Spitsbergen and Greenland. In this area significant exchange of water masses between the Arctic Ocean... view more... (2004-08-27)
When it comes to sea level changing glaciers, new NASA technique measures up
A NASA-led research team has used satellite data to make the most precise measurements to date of changes in the mass of mountain glaciers in the Gulf of Alaska, a region expected to be a significant contributor to global sea level rise over the next 50-100 years. view more (2008-11-07)
Fluorescence microscopy reveals why some antifreeze proteins inhibit ice growth better than others
Antifreeze or "ice structuring" proteins - found in some fish, insects, plants, fungi and bacteria - attach to the surface of ice crystals to inhibit their growth and keep the host organism from freezing to death. view more (2007-03-07)
Antarctic research helps shed light on climate change on Mars
Researchers examining images of gullies on the flanks of craters on Mars say they formed as recently as a few hundred thousand years ago and in sites once occupied by glaciers. The features are eerily reminiscent of gullies formed in Antarctica's mars-like McMurdo Dry Valleys. view more (2008-08-29)
NASA and USGS Produce Most Detailed Satellite Views of Antarctica
Researchers from NASA and the U.S. Geological Survey (USGS), Golden, Colo., have woven together more than a thousand images from the Landsat 7 satellite to create the most detailed, high-resolution map ever produced of Antarctica. The Landsat Image Mosaic of Antarctica (LIMA) offers views of the coldest continent on Earth in 10 times greater... view more... (2007-03-08)
Greenland's ice loss accelerating rapidly, gravity-measuring satellites reveal
A new analysis of data from twin satellites has revealed that the melting of Greenland's ice sheet has increased dramatically in the past few years, with much of the loss occurring primarily along one shoreline potentially affecting weather in Western Europe. view more (2006-08-11)
Heatwave on the top of the world
The French Intergovernmental Panel on Climate Change (IPPC, or GIEC in French) has just announced the conclusions of its 4th report, which restates that global warming has increased the average temperature by 0.74°C over the last century. view more (2007-03-02)
Has the mystery of the Antarctic ice sheet been solved?
A team of scientists from Cardiff University's School of Earth and Ocean Sciences and Amgueddfa Cymru - National Museum Wales travelled to Africa to find new evidence of climate change which helps explain some of the mystery surrounding the appearance of the Antarctic ice sheet. view more (2008-02-28)
'Finger rafting:' Ice sheets that mesh when they meet
A study reported in Physical Review Letters demonstrates how ice sheets sometimes interlace when they meet, rather than riding over or under each other, and discusses the implications for other phenomena from plate tectonics of the Earth's surface to the design of self-assembling nanostructures. view more (2007-03-02)
Ice storms devastating to pecan orchards
Ice storms and other severe weather can have devastating impacts on agricultural crops, including perennial tree crops. view more (2009-03-25)
NASA researcher finds days of snow melting on the rise in Greenland
In 2006, Greenland experienced more days of melting snow and at higher altitudes than average over the past 18 years, according to a new NASA-funded project using satellite observations. view more (2007-05-30)
LSU scientist finds evidence of 'rain-making' bacteria
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. view more (2008-02-29)
Simple test for asthma patients predicts length of hospital stay
Simple test for asthma patients predicts length of hospital stay (Peak expiratory flow sequence in acute exacerbations of asthma) BMJ Volume 322, p 1281 Measuring the change in a patient’s ability to blow three times in quick succession into a peak flow meter during an acute asthma attack predicts the length of time they will stay in... view more...

UCSB scientists propose Antarctic location for 'missing' ice sheet
New research by scientists at UC Santa Barbara indicates a possible Antarctic location for ice that seemed to be missing at a key point in climate history 34 million years ago. view more (2009-08-26)
As Greenland melts
Not that long ago - the blink of a geologic eye - global temperatures were so warm that ice on Greenland could have been hard to come by. Today, the largest island in the world is covered with ice 1.6 miles thick. Even so, Greenland has become a hot spot for climate scientists. view more (2009-10-20)
Climate change threatens Lake Baikal's unique biota
Siberia's Lake Baikal, the world's largest and most biologically diverse lake, faces the prospect of severe ecological disruption as a result of climate change, according to an analysis by a joint US-Russian team in the May issue of BioScience. view more (2009-05-01)
Improved predictions of warming-induced extinctions sought
In the March 2007 issue of BioScience, an international team of 19 researchers calls for better forecasting of the effects of global warming on extinction rates. view more (2007-03-01)
Monitoring of blood flow to the brain could prevent brain damage
University of Southampton engineers believe that monitoring blood flow to the brains of head injury patients could potentially reduce the incidence of brain damage and long-term disability, and are developing methods of using ultrasound to do this. With many years experience in studying the rise and fall of pressure inside the heads of patients... view more... (2003-04-30)
Arctic sea ice hits second-lowest extent, likely lowest volume, say CU-Boulder researchers
Arctic sea ice extent during the 2008 melt season dropped to the second-lowest level since satellite measurements began in 1979, reaching the lowest point in its annual cycle of melt and growth on Sept. 14. view more (2008-10-03)
Giants joust in the cold
A new giant was born recently in the coastal waters of Antarctica. A series of images captured from May through the beginning of this month by ESA`s Envisat satellite shows the subsequent duel between the new iceberg and another as it breaks free of the Ross Ice Shelf and tries to move north. Christened C-19 by the US National Ice Centre in... view more... (2002-10-22)
