Antarctica - an awakening giant?
The crucial role that Antarctica plays in global climate change and its future contribution to sea-level rise was highlighted today by Professor Chris Rapley, Director of British Antarctic Survey (BAS). Speaking at an international convention on climate change in Bonn, Germany* he presented a summary of the latest scientific results from... view more... (2005-05-19)
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)

UCSB scientists propose Antarctic location for 'missing' ice sheet
New research by scientists at UC Santa Barbara indicates a possible Antarctic location for ice that seemed to be missing at a key point in climate history 34 million years ago. view more (2009-08-26)
New surprising results about the research on glaciers
In order to understand the dynamics of glaciers and ice sheets as well as their interactions with climate, we need fundamental detailed knowledge about the way in which glaciers and ice sheets move. The way water is routed through glaciers is highly significant for their movement since the water pressure at the base of the glacier directly... view more... (2005-02-09)
Soviet plans implemented by Nature 90,000 years ago
One of the more controversial environmental issues, which emerged in the final years of the Soviet era, was the plan to dam and reverse the flow of north-flowing rivers in order to irrigate the dry southern steppes. This scheme was roundly criticised by scientists and environmentalists at the time because of fears for the impact on the Arctic... view more... (2002-01-22)
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)
Glimpse to past adds weight to global warming forecasts
A new examination of the period of global warming that planet Earth underwent 130,000 years ago is helping scientists to confirm the accuracy of projections for the next century - particularly over Canada's North. view more (2006-03-24)
NASA flies to Antarctica for largest airborne polar ice survey
NASA begins a series of flights Oct. 15 to study changes to Antarctica's sea ice, glaciers and ice sheets. The flights are part of Operation Ice Bridge, a six-year campaign that is the largest airborne survey ever made of ice at Earth's polar regions. view more (2009-10-09)
Melting of the Greenland ice cap may have consequences for climatic change
According to two international-research studies on the last ice age, studies with the participation of Dr Rainer Zahn, research professor in the ICREA at the UAB Institute of Environmental Science and Technology (ICTA), before the great ice sheets of the Arctic Ocean began to melt, early sporadic episodes of melting of the old ice sheet which... view more...

Ice Sheets Can Retreat
Modern glaciers, such as those making up the Greenland and Antarctic ice sheets, are capable of undergoing periods of rapid shrinkage or retreat, according to new findings by paleoclimatologists at the University at Buffalo. view more (2009-06-22)
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)
Antarctic Ice Core milestone - 2002 m reached as year 2002 arrives
In the first weeks of the New Year a team of European scientists drilled successfully through 2002 metres of ice at Dome Concordia, high on East Antarctica`s plateau - one of the most hostile places on the planet. A specially created laboratory on the ice enabled scientists to analyse, for the first time, past climate shifts within hours of each 3... view more... (2002-01-15)
US-led international research team confirms Alps-like mountain range exists
Flying twin-engine light aircraft the equivalent of several trips around the globe and establishing a network of seismic instruments across an area the size of Texas, a U.S.-led, international team of scientists has not only verified the existence of a mountain range that is suspected to have caused the massive East Antarctic Ice Sheet to form,... view more...

'Finger rafting:' Ice sheets that mesh when they meet
A study reported in Physical Review Letters demonstrates how ice sheets sometimes interlace when they meet, rather than riding over or under each other, and discusses the implications for other phenomena from plate tectonics of the Earth's surface to the design of self-assembling nanostructures. view more (2007-03-02)
Andrill demonstrates climate warming affects Antarctic ice sheet stability
A five-nation scientific team has published new evidence that even a slight rise in atmospheric concentrations of carbon dioxide, one of the gases that drives global warming, affects the stability of the West Antarctic Ice Sheet (WAIS). view more (2009-03-19)
Polar explorers use satellite broadband to stay in touch
A team of young explorers from the Climate Change College are on a ten day field trip, participating in ESA's CryoSat validation experiment on the Greenland Ice Sheet. view more (2006-05-08)
Hammering sheet metal into shape
The tool at the pressing plant resonantly pounds the sheet metal, ejecting the newly formed vehicle hood moments later. Although this operation runs like clockwork on the production line, it caused the developers of the metal-forming equipment many a headache, since sheet metal springs back (unbends elastically) when the press is opened. The... view more... (2003-02-20)
Plastic as hard and clear as glass
Plastics come in many forms. They are used to make boats, magnifiers, skis and all manner of household items. Transparent plastic sheet panels would be ideal in the manufacture of windows or headlamps of cars, for example, and tinted plastic foils could more readily be used to protect against the sun – if only the material was not so easily... view more...

Climate Research: Oldest Ice in Process
Scientists at the Alfred Wegener Institute for Polar and Marine Research (AWI) are handling the oldest ice that has ever been unearthed: The ice cores, which were drilled during last winter in the Antarctic research station Dome C, are up to 900.000 years old. They come from a depth of 3200 metres and contain information about the climate and... view more... (2003-11-14)
