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)
Methane releases from Arctic shelf may be much larger and faster than anticipated
A section of the Arctic Ocean seafloor that holds vast stores of frozen methane is showing signs of instability and widespread venting of the powerful greenhouse gas, according to the findings of an international research team led by University of Alaska Fairbanks scientists Natalia Shakhova and Igor Semiletov. view more (2010-03-05)
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)
New Antarctic ice core to provide clearest climate record yet
After enduring months on the coldest, driest, and windiest continent on Earth, researchers today closed out the inaugural season on an unprecedented, multi-year effort to retrieve the most detailed record of greenhouse gases in Earth's atmosphere over the last 100,000 years. view more (2008-01-24)
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)
For toy-like NASA robots in Arctic, ice research is child's play
Several snowmobiles navigated speedily over arctic ice and snow in Alaska's outback in late June. This scene might seem ordinary except that the recently unveiled snowmobiles are unmanned, autonomous, toy-size robots called SnoMotes - the first prototype network of their kind envisioned to rove treacherous areas of the Arctic and Antarctic... view more...

Research finds that Earth's climate is approaching 'dangerous' point
NASA and Columbia University Earth Institute research finds that human-made greenhouse gases have brought the Earth's climate close to critical tipping points, with potentially dangerous consequences for the planet. view more (2007-06-01)
Siberian lakes burp "time-bomb" greenhouse gas
Frozen bubbles in Siberian lakes are releasing methane, a greenhouse gas, at rates that appear to be "... five times higher than previously estimated" and acting as a positive feedback to climate warming, said Katey Walter, in a paper published today in the journal Nature. view more (2006-09-08)
Warming ocean contributes to global warming
The warming of an Arctic current over the last 30 years has triggered the release of methane, a potent greenhouse gas, from methane hydrate stored in the sediment beneath the seabed. view more (2009-08-17)
FSU Historian's Arctic research has him sitting on top of the world
It's one of the coldest and most remote areas on Earth, but the Arctic region has long held great strategic interest for a number of nations. Now, a Florida State University researcher is leading an international team that is working to produce one of the most comprehensive histories to date of the northernmost part of the world from the late 19th... view more...

Impact of Climate Warming on Polar Ice Sheets Confirmed
In the most comprehensive survey ever undertaken of the massive ice sheets covering both Greenland and Antarctica, NASA scientists confirm climate warming is changing how much water remains locked in Earth's largest storehouse of ice and snow. view more (2006-03-09)
Oldest Antarctic ice core reveals climate history
Secrets of the Earth's past climate locked in a three-kilometre long Antarctic ice core are revealed this week in the journal Nature. The core from Dome C, high on East Antarctica's plateau, contains snowfall from the last 740,000 years and is by far the oldest continuous climate record obtained from ice cores so far. The ice has been collected... view more... (2004-06-03)

Antarctic ice shelf 'hangs by a thread'
British Antarctic Survey has captured dramatic satellite and video images of an Antarctic ice shelf that looks set to be the latest to break out from the Antarctic Peninsula. A large part of the Wilkins Ice Shelf on the Antarctic Peninsula is now supported only by a thin strip of ice hanging between two islands. It is another identifiable impact... view more...
