Older Arctic sea ice replaced by young, thin ice, says CU-Boulder study
A new study by University of Colorado at Boulder researchers indicates older, multi-year sea ice in the Arctic is giving way to younger, thinner ice, making it more susceptible to record summer sea-ice lows like the one that occurred in 2007. view more (2008-01-14)
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)
Northern bogs may have helped kick-start past global warming
Methane gas released by peat bogs in the northern-most third of the globe probably helped fuel the last major round of global warming, which drew the ice age to a close between 11,000 and 12,000 years ago, UCLA and Russian Academy of Sciences scientists have concluded. view more (2006-10-13)
Study shows snowfall hasn't increased over Antarctica in last 50 years
An international effort to determine the variability of recent snowfall over Antarctica shows that there has been no real increase in precipitation over the southernmost continent in the last half-century. view more (2006-08-11)
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)
New Arctic satellite data shows Arctic literally on thin ice
The latest data from NASA and the University of Colorado at Boulder's National Snow and Ice Data Center show the continuation of a decade-long trend of shrinking sea ice extent in the Arctic, including new evidence for thinning ice as well. view more (2009-04-07)
Arctic sea ice recovers slightly in 2009, remains on downward trend, says U. of Colorado report
Despite a slight recovery in summer Arctic sea ice in 2009 from record-setting low years in 2007 and 2008, the sea ice extent remains significantly below previous years and remains on a trend leading toward ice-free Arctic summers, according to the University of Colorado at Boulder's National Snow and Ice Data Center. view more (2009-10-07)
Scientists discover pentagonal ice
Scientists at the University of Liverpool have discovered a five-sided ice chain structure that could be used to modify future weather patterns. view more (2009-04-07)
Role of Silica in Climate Cycles
New research from the University of East Anglia (UEA) has demonstrated that the compound silica was not solely responsible for changes in carbon dioxide levels during past Ice Ages. It is already known from scientific research that during past Ice Ages increased amounts of silica, a common component of wind-blown dust, were deposited in the ocean.... view more... (2001-06-21)
Call for responses to report on AHRB museums and galleries funding
The Arts and Humanities Research Board (AHRB) is seeking responses to its report on the funding of English university museums and galleries. The report sets out the AHRB's intentions for the future of its core funding scheme for university museums and galleries in England. A number of key issues have been identified as areas of particular... view more... (2004-08-04)
Cooling with tiny crystals
Refrigeration equipment prevents sweaty brows in the summer and also keeps our food fresh for longer periods. With CryoSol®, a new and easily pumpable liquid ice suspension, space requirements for cold storage are much lower than with conventional coolants. view more (2004-08-27)
Surprisingly rapid changes in the Earth's core discovered
In a recent paper published in Nature Geoscience, the geophysicist Mioara MANDEA from the GFZ German Research Centre for Geosciences, Potsdam and her Danish colleague Nils OLSEN from the National Space Institute/DTU Copenhagen, have shown that motions in the fluid in the Earth's core are changing surprisingly fast, and that this, in turn, effects... view more...

Higher Water Temperatures and Reduced Ice Cover In the Arctic Ocean
Over the past six weeks, scientists aboard the research vessel "Polarstern" of the Alfred Wegener Institute for Polar and Marine Research have been investigating changes in ocean temperature and sea ice cover in the area of Fram Strait between Spitsbergen and Greenland. In this area significant exchange of water masses between the Arctic Ocean... view more... (2004-08-27)
Global warming, Antarctic ice is focus of multinational workshop
As the national repository for geological material from the Southern Ocean, the Antarctic Marine Geology Research Facility at Florida State University houses the premier collection of Antarctic sediment cores -- and a hot new acquisition will offer an international team of scientists meeting there May 1-4 its best look yet at the impact of global... view more...

North America's northernmost lake affected by global warming
Analyses conducted by researchers from Universite Laval's Center for Northern Studies reveal that the continent's northernmost lake is affected by climate change. view more (2007-09-27)
Getting to the core of the problem - CMD19CMMP with
Using the equations of quantum mechanics, which normally govern the bizarre physics that occurs at tiny atomic scales, has enabled geophysicists to answer a much larger-scale question - what the Earth`s core is made from. At the Condensed Matter physics conference on Tuesday 9 April, part of the Institute of Physics Congress in Brighton, Prof Mike... view more... (2002-03-26)
New ice cores expand view of climate history
Two new studies of gases trapped in Antarctic ice cores have extended the record of Earth's past climate almost 50 percent further, adding another 210,000 years of definitive data about the makeup of the Earth's atmosphere and providing more evidence of current atmospheric change. view more (2005-11-28)
Fluorescence microscopy reveals why some antifreeze proteins inhibit ice growth better than others
Antifreeze or "ice structuring" proteins - found in some fish, insects, plants, fungi and bacteria - attach to the surface of ice crystals to inhibit their growth and keep the host organism from freezing to death. view more (2007-03-07)
Largest collection of anomalous white dwarfs observed in new Hubble images
Twenty-four unusual stars, 18 of them newly discovered, have been observed in new Hubble telescope images. The stars are white dwarfs, a common type of dead star, but they are odd because they are made of helium rather than the usual carbon and oxygen. This is the first extensive sequence of helium-core white dwarfs to be observed in a globular... view more... (2009-04-23)
Europa does the wave to generate heat
One of the moons in our solar system that scientists think has the potential to harbor life may have a far more dynamic ocean than previously thought. view more (2008-12-12)
