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 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)
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 other similar meteorites. view more (2008-03-14)
Has the mystery of the Antarctic ice sheet been solved?
A team of scientists from Cardiff University's School of Earth and Ocean Sciences and Amgueddfa Cymru - National Museum Wales travelled to Africa to find new evidence of climate change which helps explain some of the mystery surrounding the appearance of the Antarctic ice sheet. view more (2008-02-28)
Observing sustainable tourism in Antarctica
"Antarctica is the ultimate destination for anyone interested in natural history but it also challenges those people who visit to think broadly about our responsibilities to all life on Earth." That's the view of Dr Robert Lambert, a lecturer on Tourism and the Environment at The University of Nottingham, who has just returned from the... view more... (2008-02-25)
Scientists Discover 'giant fossil frog from hell'
A team of researchers, led by Stony Brook University paleontologist David Krause, has discovered the remains in Madagascar of what may be the largest frog ever to exist. view more (2008-02-20)
Emory Researcher Finds Crayfish Fossils Provide Missing Evolutionary Link
Crayfish body fossils and burrows discovered in Victoria, Australia, have provided the first physical evidence that crayfish existed on the continent as far back as the Mesozoic Era, says Emory University paleontologist Anthony Martin, who headed up a study on the finds. view more (2008-02-07)
International team establishes unique observatory in Antarctica
A team of scientists representing six international institutions, including Texas A&M University, has succeeded in reaching the summit of Antarctica - also a monumental achievement for ground-based astronomy -- to establish a new astronomical observatory at Dome Argus on the highest point of the Antarctic Plateau. view more (2008-02-04)
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)
First evidence of under-ice volcanic eruption in Antarctica
The first evidence of a volcanic eruption from beneath Antarctica's most rapidly changing ice sheet is reported this week in the journal Nature Geosciences. The volcano on the West Antarctic Ice Sheet erupted 2000 years ago (325BC) and remains active. view more (2008-01-21)
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)
Earth's heat adds to climate change to melt Greenland ice
Scientists have discovered what they think may be another reason why Greenland's ice is melting: a thin spot in Earth's crust is enabling underground magma to heat the ice. They have found at least one "hotspot" in the northeast corner of Greenland -- just below a site where an ice stream was recently discovered. view more (2007-12-13)
Massive dinosaur discovered in Antarctica sheds light on life, distribution of sauropodomorphs
A new genus and species of dinosaur from the Early Jurassic has been discovered in Antarctica. The massive plant-eating primitive sauropodomorph is called Glacialisaurus hammeri and lived about 190 million years ago. view more (2007-12-11)
'Magma P.I.' unearths clues to how crust was sculpted
About a decade ago, Johns Hopkins University geologist Bruce Marsh challenged the century-old concept that the Earth's outer layer formed when crystal-free molten rock called magma oozed to the surface from giant subterranean chambers hidden beneath volcanoes. view more (2007-12-04)
NASA-conceived map of Antarctica lays ground for new discoveries
A team of researchers from NASA, the U.S. Geological Survey, the National Science Foundation and the British Antarctic Survey unveiled a newly completed map of Antarctica today that is expected to revolutionize research of the continent's frozen landscape. view more (2007-11-28)
ANDRILL's 2nd Antarctic drilling season exceeds all expectations
A second season in Antarctica for the Antarctic Geological Drilling (ANDRILL) Program has exceeded all expectations, according to the co-chief scientists of the program's Southern McMurdo Sound Project. view more (2007-11-28)
Emory paleontologist reports discovery of carnivorous dinosaur tracks in Australia
The first fossil tracks belonging to large, carnivorous dinosaurs have been discovered in Victoria, Australia, by paleontologists from Emory University, Monash University and the Museum of Victoria (both in Melbourne). view more (2007-10-22)
Cold colony vulnerable to environmental challenge
Australia and other owners of the Antarctic territories may be ill-prepared to face a major environmental challenge to the continent, according to a Queensland University of Technology academic. view more (2007-10-19)
