Strengthening case for life on Mars - CMD19CMMP with The Physics Congress 2002
When it was announced last month that the Mars Odyssey satellite had found water ice beneath the planet`s frozen carbon dioxide south polar ice cap, "I felt excited!" says Dr Lidija Siller, a physicist from the University of Newcastle. "I believe that the data I have explains how this water became trapped underneath the surface". Dr Siller will be... view more... (2002-03-26)
Scientists Detect Melting of Antarctic Ice Shelf
A giant ice shelf the size of Scotland is melting rapidly in warm Antarctic waters, a report in SCIENCE will reveal today. Thinning of the Larsen Ice Shelf - vast sections of which collapsed catastrophically during the 1990's - was discovered by scientists at the University of Cambridge, University College London, University of Bristol and the... view more...

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)
Forecasting where and when the rain will fall
Leeds researchers are aiming to unlock the secrets of the British weather, bringing forecasters one step closer to that elusive holy grail: the ability to predict exactly where, when and how much rain is going to fall. Dr Alan Blyth from the school of the environment explains: "There's still a lot we don't know about exactly how rain is... view more... (2003-11-24)
Arctic Sea ice extent is third lowest on record
U.S. satellite measurements show Arctic sea ice extent in 2009 - the area of the Arctic Ocean covered by floating ice - was the third lowest since satellite measurements were first made in 1979. view more (2009-10-07)
New Glacier Outburst Flood in Iceland
On July 9th researchers from Keele and Staffordshire Universities and the Icelandic Meteorological Office identified the source and drainage routes of a glacier outburst flood or 'jokulhlaup' which is currently draining from the western margin of Vatnajokull ice cap. The team are currently part of an Earthwatch funded project based at Skaftafell... view more... (2002-07-09)
Cooling Off Periods
Research by a team of Cambridge scientists has provided new clues about the first dramatic cooling of the Earth's climate 34 million years ago. The team, based at the University of Cambridge's Department of Earth Sciences said that ocean temperature drops were apparently not responsible for the rapid formation of ice in Antarctica. Carrie Lear,... view more... (2000-01-12)
International Greenland ice coring effort sets new drilling record in 2009
A new international research effort on the Greenland ice sheet with the University of Colorado at Boulder as the lead U.S. institution set a record for single-season deep ice-core drilling this summer, recovering more than a mile of ice core that is expected to help scientists better assess the risks of abrupt climate change in the future. view more (2009-08-27)
Exploding Bubbles Detected by Laser Light
A revolutionary way of detecting the potentially dangerous gas bubbles in bore-holes that can lead to large explosions, is reported today in the Institute of Physics journal, Measurement Science and Technology. The new technique, developed by researchers at the University of Reading, could save the oil exploration industry millions of pounds by... view more... (2000-05-30)
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)
CryoSat - a satellite with an icy mission
On 8 February the ESA Director of Earth Observation, José Achache, signed the contract confirming that Astrium will build the new European environmental and climate satellite CryoSat. The satellite is planned for an April 2004 launch into a polar orbit and will measure changes in the thickness of ice sheets and polar ocean sea-ice cover... view more... (2002-02-08)
The tropics play a more active role than was thought in controlling the Earth's climate
Researchers from the Universitat Aut√≤noma de Barcelona and Durham University (UK) have discovered that a million years ago, global climate changes occurred due to changes in tropical circulation in the Pacific similar to those caused by El Ni√ħo today. view more (2005-10-12)
CARBON FIBRE COULD HELP BEAT TRAFFIC JAMS
Thin sheets of carbon fibre could provide a new way of repairing bridges quickly and increasing their life-span. The technique would also reduce the disruption to traffic caused by conventional repair techniques. view more (1999-05-20)
Record warm summers cause extreme ice melt in Greenland
An international team of scientists, led by Dr Edward Hanna at the University of Sheffield, has demonstrated that recent warm summers have caused the most extreme Greenland ice melting in 50 years. view more (2008-01-16)
West Antarctic ice sheet may not be losing ice as fast as once thought
New ground measurements made by the West Antarctic GPS Network (WAGN) project, composed of researchers from The University of Texas at Austin, The Ohio State University, and The University of Memphis, suggest the rate of ice loss of the West Antarctic ice sheet has been slightly overestimated. view more (2009-10-20)
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)
New predictions for sea level rise
Fossil coral data and temperature records derived from ice-core measurements have been used to place better constraints on future sea level rise, and to test sea level projections. view more (2009-07-27)
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...

Egg-shaped legacy of Britain's mobile ice-sheet
The ice sheets that sculpted the landscape of northern Britain moved in unexpected ways and left distinctive egg-shaped features according to new research. view more (2009-09-16)
Research team draws 150-meter ice core from McCall Glacier
A 150-meter ice core pulled from the McCall Glacier in the Arctic National Wildlife Refuge this summer may offer researchers their first quantitative look at up to two centuries of climate change in the region. view more (2008-07-11)
