Greenland ice sheet still losing mass, says new University of Colorado study
Data gathered by a pair of NASA satellites orbiting Earth show Greenland continued to lose ice mass at a significant rate through April 2006, and that the rate of loss is accelerating, according to a new University of Colorado at Boulder study. view more (2006-09-21)
Antarctic glacier thinning at alarming rate
The thinning of a gigantic glacier in Antarctica is accelerating, scientists warned today. The Pine Island Glacier in West Antarctica, which is around twice the size of Scotland, is losing ice four times as fast as it was a decade years ago. view more (2009-08-14)
Antarctic ice shelf disintegrating as result of climate change, say scientists
Satellite imagery from the University of Colorado at Boulder's National Snow and Ice Data Center shows a portion of Antarctica's massive Wilkins Ice Shelf has begun to collapse because of rapid climate change in a fast-warming region of the continent. view more (2008-03-26)
Chance discovery: Alaska Range glacier surges
There is evidence that the McGinnis Glacier, a little-known tongue of ice in the central Alaska Range, has surged. view more (2006-03-16)
New Antarctic seabed sonar images reveal clues to sea-level rise
Motorway-sized troughs and channels carved into Antarctica's continental shelves by glaciers thousands of years ago could help scientists to predict future sea-level rise. view more (2009-05-05)
Humans inhabited New World's doorstep for 20,000 years
The human journey from Asia to the New World was interrupted by a 20,000-year layover in Beringia, a once-habitable region that today lies submerged under the icy waters of the Bering Strait. view more (2008-02-13)
Study assesses impact of fish stocking on aquatic insects
The impact fish stocking has on aquatic insects in mountain lakes can be rapidly reversed by removing non-native trout, according to a study completed by U.S. Forest Service and University of California, Davis, scientists. view more (2009-03-27)
***Changed embargo time***Rising sea levels could be 'cancelled out' by increased snowfall
A paper published today in Science shows that the largest ice sheet in the world, the East Antarctic Ice Sheet, is growing due to increased snow fall. This growth partly mitigates the sea level rise caused by melting glaciers in other areas, especially Greenland. view more (2005-05-17)
Where Does the North Pole Ice Come From? The Origin of the Northern Hemisphere Ice Age
Large areas of the Northern Hemisphere are currently covered with ice. This has, however, not always been the case. In the current issue of the science magazine "Nature", scientists from the GeoForschungsZentrum Potsdam (GFZ) and the Potsdam Institute for Climate Impact Research (PIK) present a possible solution for the oldest mystery of palaeo... view more...

Antarctic ice shelf retreats happened before
The retreat of Antarctic ice shelves is not new according to research published this week (24 Feb) in the journal Geology by scientists from Universities of Durham, Edinburgh and British Antarctic Survey (BAS). view more (2005-02-23)
Mapping a glacial path of destruction
The dangerous power of glacial outburst floods—or jokulhlaups—will be easier to predict thanks to new models developed by a Leeds researcher and presented at the International Glaciological Society symposium in Iceland this Friday (June 23). view more (2006-06-20)
Why oceans behave like water in a bath
SATELLITE measurements of sea levels have uncovered a bizarre effect. The sea seems to be rising faster near the coast than in mid-ocean. Simon Holgate and Philip Woodworth of the Proudman Oceanographic Laboratory, in Bidston, UK, found this discrepancy using the Topex satellite, launched in 1992. The satellite measures sea level by bouncing... view more... (2004-04-21)
Black carbon pollution emerges as major player in global warming
Black carbon, a form of particulate air pollution most often produced from biomass burning, cooking with solid fuels and diesel exhaust, has a warming effect in the atmosphere three to four times greater than prevailing estimates, according to scientists in an upcoming review article in the journal Nature Geoscience. view more (2008-03-24)
Better estimates for future extreme precipitation in Europe
Researchers in Switzerland report that extreme rains in Europe may grow stronger and more frequent in the near future and have significant effects on the region's infrastructure and natural systems. view more (2006-03-30)
Century of data shows intensification of water cycle but no increase in storms or floods
A review of the findings from more than 100 peer-reviewed studies shows that although many aspects of the global water cycle have intensified, including precipitation and evaporation, this trend has not consistently resulted in an increase in the frequency or intensity of tropical storms or floods over the past century. view more (2006-03-16)
Acid Soils in Slovakia Tell Somber Tale
Increasing levels of nitrogen deposition associated with industry and agriculture can drive soils toward a toxic level of acidification, reducing plant growth and polluting surface waters, according to a new study published online in Nature Geoscience. view more (2008-11-18)
Swedish researchers fly all the way to the Antarctic
Participants in the second part of this winter's polar expedition to the Antarctic, SWEDARP 2002/03, are ready to depart. Today, Monday, January 20, five members of the expedition will leave Sweden to join the group of ten researchers already on site in Antarctica as of the middle of December. Swedish scientists in the fields of glaciology,... view more... (2003-01-20)
Global change conference sets the scene for next round of Kyoto Protocol talks
Throughout the world, scientists are seeing clear signs that the Earth is rapidly changing. Tropical glaciers are melting fast and some will disappear within 15 years if current warming trends continue. Fifty percent of the land surface has been modified and more than half the world’s accessible freshwater is being used directly or... view more... (2001-04-10)
Earthworm activity can alter forests' carbon-carrying capabilities
Earthworms can change the chemical nature of the carbon in North American forest litter and soils, potentially affecting the amount of carbon stored in forests, according to Purdue University researchers. view more (2008-10-28)
Bacteria discovery aids food production, water purification
The search for a type of bacteria that creates better ice cream and artificial snow has suddenly become a lot easier, thanks to a discovery by Queen's University biologist Virginia Walker. view more (2006-10-02)
