2008 ozone hole larger than last year
The 2008 ozone hole - a thinning in the ozone layer over Antarctica - is larger both in size and ozone loss than 2007 but is not as large as 2006.   view more (2008-10-08)

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)

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)

Arctic ice on the verge of another all-time low
Following last summer's record minimum ice cover in the Arctic, current observations from ESA's Envisat satellite suggest that the extent of polar sea-ice may again shrink to a level very close to that of last year.   view more (2008-08-29)

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)

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)

Patagonian glacier yields clues for improved understanding of global climate change
A better understanding of climate variations at planetary scale is one of climate scientists' crucial concerns. Stable water isotope analysis, the chemistry of ice cores taken from the Arctic and Antarctic polar ice caps and of air bubbles trapped in them now allow a chronology to be drawn up of... view more (2008-08-05)

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)

Unique fossil discovery shows Antarctic was once much warmer
A new fossil discovery- the first of its kind from the whole of the Antarctic continent- provides scientists with new evidence to support the theory that the polar region was once much warmer.   view more (2008-07-23)

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)

Pocket-sized magnetic resonance imaging
The term "MRI scan" brings to mind the gigantic, expensive machines that are installed in hospitals. But research scientists have now developed small portable MRI scanners that perform their services in the field: for instance to examine ice cores.    view more (2008-07-09)

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)

Ocean satellite launch critical to Australian science
A new earth observing satellite being launched in California today will help guide future Australian ocean and climate science.   view more (2008-06-23)

Ocean warming on the rise
Increased scientific confidence that ocean observations are accurately reflecting rising global temperatures is central to new Australian research published today in the journal, Nature.   view more (2008-06-19)

Ocean temperatures and sea level increases 50 percent higher than previously estimated
New research suggests that ocean temperature and associated sea level increases between 1961 and 2003 were 50 percent larger than estimated in the 2007 Intergovernmental Panel on Climate Change report.    view more (2008-06-19)

Computer models show major climate shift as a result of closing ozone hole
A new study led by Columbia University researchers has found that the closing of the ozone hole, which is projected to occur sometime in the second half of the 21st century, may significantly affect climate change in the Southern Hemisphere, and therefore, the global climate.   view more (2008-06-13)

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)

'New' ancient Antarctic sediment reveals climate change history
Recent additions to the premier collection of Southern Ocean sediment cores at Florida State University's Antarctic Marine Geology Research Facility will give international scientists a close-up look at fluctuations that occurred in Antarctica's ice sheet and marine and terrestrial life as the... view more (2008-04-29)

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)

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)

Tuatara, the fastest evolving animal
In a study of New Zealand's "living dinosaur" the tuatara, evolutionary biologist, and ancient DNA expert, Professor David Lambert and his team from the Allan Wilson Centre for Molecular Ecology and Evolution recovered DNA sequences from the bones of ancient tuatara, which are up to 8000... view more (2008-03-24)

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)
