Antarctic ice loss
Increasing amounts of ice mass have been lost from West Antarctica and the Antarctic peninsula over the past ten years, according to research from the University of Bristol and published online this week in Nature Geoscience. view more (2008-01-14)
NASA mission checks health of Greenland's ice sheet and glaciers
A NASA-led research team has returned from Greenland after an annual three-week mission to check the health of its glaciers and ice sheet. About 82 percent of Greenland is made up of a giant ice sheet. view more (2007-05-31)
Climate kick from the Southern Ocean
This much was already known: in the closing phase of the last ice age the Southern Hemisphere began warming first. As a result, the Antarctic sea ice melted. It was at least a thousand years later - as evidenced by investigations of Greenland ice cores - that the high northern latitudes began to get warmer. Sea ice in the North Atlantic retreated... view more... (2003-07-29)
Antarctic Ice Sheet's Hidden Lakes Speed Ice Flow Into Ocean, May Disrupt Climate
Just as explorers once searched the vast reaches of Africa's Nile River for clues to its behavior and ultimate source, modern-day scientists are searching Antarctica for its hidden lakes and waterways that can barely be detected at the surface of the ice sheet. view more (2007-03-07)
Data show Antarctic ice stream radiating seismically
A seismologist at Washington University in St. Louis and colleagues at Pennsylvania State University and Newcastle University in the United Kingdom have found seismic signals from a giant river of ice in Antarctica that makes California's earthquake problem seem trivial. view more (2008-06-05)
Russia Returns To Arctic On A Drifting Ice-floe
After a long break Russia is getting ready to resume the research in Arctic with the help of floating stations. As Valery Martyshenko (Rosgidromet) has advised InformNauka, an appropriate ice-floe is currently being looked for, and the 32nd station will start the floating in the last decade of April. Vladimir Sokolov, Head of the SP-32 floating... view more... (2003-03-25)
UK Princess sees oldest ice on earth
Princess Anne, currently visiting Antarctica, was today given a gift of ice that is 50000 years old. It came from an ice core - a cylinder of ice drilled from the Antarctic ice sheet - drilled by the European Project for Ice Coring in Antarctica (EPICA). EPICA, a consortium of 10 European nations, is drilling two ice cores in Antarctica, in order... view more... (2002-02-08)
US-led international research team confirms Alps-like mountain range exists
Flying twin-engine light aircraft the equivalent of several trips around the globe and establishing a network of seismic instruments across an area the size of Texas, a U.S.-led, international team of scientists has not only verified the existence of a mountain range that is suspected to have caused the massive East Antarctic Ice Sheet to form,... view more...

Scientists want to solve puzzle of excess water vapor near cirrus clouds
A number of researchers in recent years have reported perplexing findings of water vapor at concentrations as much as twice what they should be in and around cirrus clouds high in the atmosphere, a finding that could alter some conclusions about climate change. view more (2006-12-01)
Researchers link Ice Age climate-change records to ocean salinity
Sudden decreases in temperature over Greenland and tropical rainfall patterns during the last Ice Age have been linked for the first time to rapid changes in the salinity of the north Atlantic Ocean. view more (2006-10-05)
Arctic sea ice minimum shatters all-time record low, report University of Colorado scientists
Scientists from the University of Colorado at Boulder's National Snow and Ice Data Center said today that the extent of Arctic sea ice appears to have reached its minimum for 2007 on Sept. 16, shattering all previous lows since satellite record-keeping began nearly 30 years ago. view more (2007-09-21)
IU sends innovative technology to Antarctica to speed polar research
Environmental scientists studying the world's shrinking polar ice sheets will soon get a substantial boost in computing power thanks to IU's Polar Grid Project. view more (2008-09-23)
Global warming could lead to a greener Greenland (embargoed until 18.00 BST)
Research published in Nature suggests that enough greenhouse gases could be in the atmosphere as early as 2050 to melt the massive ice-sheet that covers Greenland. As a result, sea levels could rise by around seven metres over the next 1,000 years. Along with colleagues in Belgium and Germany, Dr Jonathan Gregory, of the Centre for Global... view more...

Glaciers not on simple, upward trend of melting
Two of Greenland's largest glaciers shrank dramatically and dumped twice as much ice into the sea during a period of less than a year between 2004 and 2005. And then, less than two years later, they returned to near their previous rates of discharge. view more (2007-02-13)
Antarctic seabirds and climate change
Recent changes in Antarctic seabird populations may be linked to environmental change according to scientists reporting in the journal Science this week. Researchers from the Cambridge-based British Antarctic Survey (BAS) reviewed the best available data from a range of long-term studies to test the view that warming of the Earth`s climate is... view more...

Antarctic ice loss speeds up, nearly matches Greenland loss
Ice loss in Antarctica increased by 75 percent in the last 10 years due to a speed-up in the flow of its glaciers and is now nearly as great as that observed in Greenland, according to a new, comprehensive study by UC Irvine and NASA scientists. view more (2008-01-24)
New research provides insight into ice sheet behavior
A new study published this week takes scientists a step further in their quest to understand how Antarctica's vast glaciers will contribute to future sea-level rise. view more (2009-07-21)
Threat from West Antarctica less than previously believed
The potential contribution to sea level rise from a collapse of the West Antarctic Ice Sheet (WAIS) have been greatly overestimated, according to a new study published in the journal Science. view more (2009-05-15)
Researchers say Arctic sea ice still at risk despite cold winter
Using the latest satellite observations, NASA researchers and others report that the Arctic is still on "thin ice" when it comes to the condition of sea ice cover in the region. A colder-than-average winter in some regions of the Arctic this year has yielded an increase in the area of new sea ice, while the older sea ice that lasts for... view more... (2008-03-19)
Robot submarine reveals secret stash of key Antarctic food source under sea ice
A robot submarine expedition under the Antarctic sea ice has discovered a major food reserve in the Southern Ocean. The findings, reported this week in SCIENCE, show a dense band of the shrimp-like krill under the ice, five times more concentrated than in open water. The importance of sea ice as a nursery for krill - key food for penguins, whales... view more... (2002-03-05)
