Abrupt Climate Shifts May Come Sooner, Not Later
The United States could suffer the effects of abrupt climate changes within decades-sooner than some previously thought--says a new government report.   view more (2008-12-22)

Measuring water from space
Observations from satellites now allow scientists to monitor changes to water levels in the sea, in rivers and lakes, in ice sheets and even under the ground. As the climate changes, this information will be crucial for monitoring its effects and predicting future impacts in different regions.   view more (2008-11-13)

Scientists probe Antarctic glaciers for clues to past and future sea level
Scientists from the U.S., U.K. and Australia have teamed up to explore two of the last uncharted regions of Earth, the Aurora and Wilkes Subglacial Basins, immense ice-buried lowlands in Antarctica with a combined area the size of Mexico.   view more (2008-10-28)

U.S.-Led, International AGAP Team Poised to Probe One of Antarctica's Last Unexplored Places
A U.S.-led, multinational team of scientists from six nations will pierce the mysteries of one of the globe's last major unexplored places this month. Using sophisticated airborne radar and other Information Age tools and techniques, the scientists will virtually "peel away" more than... view more (2008-10-15)

Gas from the past gives scientists new insights into climate and the oceans
In recent years, public discussion of climate change has included concerns that increased levels of carbon dioxide will contribute to global warming, which in turn may change the circulation in the earth's oceans, with potentially disastrous consequences.   view more (2008-10-06)

Advice from research: market visiting rights to Antarctica
Tourism on Antarctica is increasing and that can form a threat for the vulnerable South Pole area. Research from Maastricht University provides a possible solution: market the visitor rights to the highest bidder.   view more (2008-09-29)

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)

My, what big teeth you had! Extinct species had large teeth on roof of mouth
When the world's land was congealed in one supercontinent 240 million years ago, Antarctica wasn't the forbiddingly icy place it is now. But paleontologists have found a previously unknown amphibious predator species that probably still made it less than hospitable.   view more (2008-09-12)

Ice core studies confirm accuracy of climate models
An analysis has been completed of the global carbon cycle and climate for a 70,000 year period in the most recent Ice Age, showing a remarkable correlation between carbon dioxide levels and surprisingly abrupt changes in climate.   view more (2008-09-12)

Experts meet on need for new rules to govern world's fragile polar regions
A new co-ordinated international set of rules to govern commercial and research activities in both of Earth's polar regions is urgently needed to reflect new environmental realities and to temper pressure building on these highly fragile ecosystems, according to several of the experts convening in... view more (2008-09-08)

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)

Antarctic Fossils Paint a Picture of a Much Warmer Continent
National Science Foundation-funded scientists working in an ice-free region of Antarctica have discovered the last traces of tundra--in the form of fossilized plants and insects--on the interior of the southernmost continent before temperatures began a relentless drop millions of years ago.   view more (2008-08-06)

Snapshot of past climate reveals no ice in Antarctica millions of years ago
A snapshot of New Zealand's climate 40 million years ago reveals a greenhouse Earth, with warmer seas and little or no ice in Antarctica, according to research published this week in the journal Geology.    view more (2008-07-29)

Wilkins Ice Shelf hanging by its last thread
The Wilkins Ice Shelf is experiencing further disintegration that is threatening the collapse of the ice bridge connecting the shelf to Charcot Island. Since the connection to the island in the image centre helps to stabilise the ice shelf, it is likely the break-up of the bridge will put the... view more (2008-07-11)

Human influences challenge penguin populations
The ecology of penguins makes these iconic swimming and diving seabirds of the Southern Hemisphere unusually susceptible to environmental changes.   view more (2008-07-01)

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)

Climate Models Overheat Antarctica, New Study Finds
Computer analyses of global climate have consistently overstated warming in Antarctica, concludes new research by scientists at the National Center for Atmospheric Research (NCAR) and Ohio State University.   view more (2008-05-08)

Ozone hole recovery may reshape southern hemisphere climate change
A full recovery of the stratospheric ozone hole could modify climate change in the Southern Hemisphere and even amplify Antarctic warming, according to scientists from the University of Colorado at Boulder, the National Oceanic and Atmospheric Administration and NASA.   view more (2008-04-25)

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... view more (2008-03-26)

Living fossil still calls Australia home
They are separated by a vast ocean and by millions of years, but tiny prehistoric bones found on an Australian farm have been directly linked to a strange and secretive little animal that lives today in the southern rainforests of South America.   view more (2008-03-26)

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)

Unmanned aerial vehicles mark robotic first for British Antarctic Survey
Scientists at British Antarctic Survey (BAS) in collaboration with the Technical University of Braunschweig (TUBS), Germany have completed the first ever series of flights by autonomous unmanned aerial vehicles (UAVs) in Antarctica.   view more (2008-03-19)

Meteorites are rich in the building blocks of life, claims new research
Amino acids that are the building blocks of life have been found in their highest ever concentration in two ancient meteorites which crashed to Earth millions of years ago, scientists claim today.   view more (2008-03-14)

Meteorites a rich source for primordial soup
The organic soup that spawned life on Earth may have gotten generous helpings from outer space, according to a new study. Scientists at the Carnegie Institution have discovered concentrations of amino acids in two meteorites that are more than ten times higher than levels previously measured in... view more (2008-03-14)

ASU researcher may have discovered key to life before its origin on Earth
An important discovery has been made with respect to the mystery of "handedness" in biomolecules. Researchers led by Sandra Pizzarello, a research professor at Arizona State University, found that some of the possible abiotic precursors to the origin of life on Earth have been shown to... view more (2008-02-29)
