New Glacier Outburst Flood in Iceland
On July 9th researchers from Keele and Staffordshire Universities and the Icelandic Meteorological Office identified the source and drainage routes of a glacier outburst flood or 'jokulhlaup' which is currently draining from the western margin of Vatnajokull ice cap. The team are currently part of an Earthwatch funded project based at Skaftafell... view more... (2002-07-09)
Why is Greenland covered in ice?
There have been many reports in the media about the effects of global warming on the Greenland ice-sheet, but there is still great uncertainty as to why there is an ice-sheet there at all. view more (2008-08-28)
Mars With Ice, Shaken, Not Stirred
Mars, like Earth, is a climate-fickle water planet. The main difference, of course, is that water on the frigid Red Planet is rarely liquid, preferring to spend almost all of its time traveling the world as a gas or churning up the surface as ice. view more (2007-10-26)
Satellites can help Arctic grazers survive killer winter storms
Rain falling on snow sounds like a relatively harmless weather event, but when it happens in the far north it can mean lingering death for reindeer, musk oxen and other animals that normally graze on the Arctic tundra. view more (2008-03-19)
Scientists: Polar ice clouds may be climate change symptom
As the late summer sun sets in the Arctic, bands of wispy, luminescent clouds shine against the deep blue of the northern sky. view more (2007-08-21)
Melting Greenland Ice Sheets May Threaten Northeast United States, Canada
Melting of the Greenland ice sheet this century may drive more water than previously thought toward the already threatened coastlines of New York, Boston, Halifax, and other cities in the northeastern United States and Canada. view more (2009-05-28)
Are Ice Age relics the next casualty of climate change?
The Wildlife Conservation Society (WCS) recently launched a four-year study to determine if climate change is affecting populations of a quintessential Arctic denizen: the rare musk ox. view more (2008-04-25)
The last stage of an arctic odyssey
The French explorer, Gilles Elka'-m, who left North Cape (Norway) in May 2000, has almost completed the seventh and final stage of his 12,000 km solo trek along the rim of the Arctic Ocean, from the Atlantic to the Pacific, on foot, kayak, skis, by sled pulled by himself or by dogs... with help from ESA. The "Arktika" expedition is... view more... (2004-03-30)
Global warming plus natural bacteria could release vast carbon deposits currently stored in Arctic soil
Increasing concentrations of carbon dioxide in the atmosphere will make global temperatures rise. By studying soil cores from the Arctic, scientists have discovered that this rise in temperature stimulates the growth of microorganisms that can break down long-term stores of carbon, releasing them into the atmosphere as carbon dioxide. This will... view more... (2005-05-05)
International Greenland ice coring effort sets new drilling record in 2009
A new international research effort on the Greenland ice sheet with the University of Colorado at Boulder as the lead U.S. institution set a record for single-season deep ice-core drilling this summer, recovering more than a mile of ice core that is expected to help scientists better assess the risks of abrupt climate change in the future. view more (2009-08-27)
Record warm summers cause extreme ice melt in Greenland
An international team of scientists, led by Dr Edward Hanna at the University of Sheffield, has demonstrated that recent warm summers have caused the most extreme Greenland ice melting in 50 years. view more (2008-01-16)
UA scientists seek new emphases in Arctic climate change research
Much of circumpolar Arctic research focuses on the physical, direct changes resulting from climate warming such as sea ice retreat and temperature increases. view more (2009-09-11)
2000 meters deep in Antarctic ice
European ice core drilling project at Kohnen station retrieves old ice for climate research. At the Kohnen station operated by Alfred-Wegener-Institute for Polar- and Marine Research, Bremerhaven, the international drilling team reached a depth of 2000 meters on January 7 at 0210 hours. The ice from that depth is about 100.000 years old and yields... view more... (2004-01-08)
Water at Martian south pole
Thanks to ESA's Mars Express, we now know that Mars has vast fields of perennial water ice, stretching out from the south pole of the Red Planet. Astronomers have known for years that Mars possessed polar ice caps, but early attempts at chemical analysis suggested only that the northern cap could be composed of water ice, and the southern cap... view more...

Dust may settle unanswered questions on Antarctica
Dust trapped deep in Antarctic ice sheets is helping scientists unravel details of past climate change. view more (2009-03-30)
Arctic soil reveals climate change clues
Frozen arctic soil contains nearly twice the greenhouse-gas-producing organic material as was previously estimated, according to recently published research by University of Alaska Fairbanks scientists. view more (2008-10-08)
Greenland and Antarctic ice sheet melting, rate unknown
The Greenland and Antarctica ice sheets are melting, but the amounts that will melt and the time it will take are still unknown, according to Richard Alley, Evan Pugh professor of geosciences, Penn State. view more (2009-02-17)
Ice study could stop people slip-sliding away
Going out and about in freezing conditions could become safer thanks to fundamental research at the University of Edinburgh into how we slip on ice. view more (2004-12-09)
Remnants of ice age linger in gravity
Researchers have uncovered a large area of low but increasing gravity over North America - the lingering effect of the last ice age when sheets of ice sometimes three kilometres thick covered nearly all of Canada and the northeastern U.S. view more (2007-05-11)
Food shortages threaten Antarctic wildlife
Antarctic whales, seals and penguins could be threatened by food shortages in the Southern Ocean. Numbers of Antarctic krill (Euphausia superba), a shrimp-like crustacean at the heart of the food chain, are declining. The most likely explanation is a dramatic decline in sea-ice. The results are published this week in the journal Nature. view more (2004-11-01)
