Dust may settle unanswered questions on Antarctica
Dust trapped deep in Antarctic ice sheets is helping scientists unravel details of past climate change. view more (2009-03-30)
Earth's core rotates faster than its crust, scientists say
Scientists have ended a 9-year-old debate by proving that Earth's core rotates faster than its surface, by about 0.3 to 0.5 degree per year. view more (2005-08-26)
Greenland and Antarctic ice sheet melting, rate unknown
The Greenland and Antarctica ice sheets are melting, but the amounts that will melt and the time it will take are still unknown, according to Richard Alley, Evan Pugh professor of geosciences, Penn State. view more (2009-02-17)
World premier for newly composed music for ice instruments
World premier for newly composed music for ice instruments: The ensemble "Voices of Ice" play at the Ice Globe Theater in the northern part of Sweden. Tuesday, March 18 is the world premier at the Ice Globe Theater in Jukkasj'Īrvi for two newly composed musical pieces by the Swedish composers Karin Rehnqvist and Bill Brunson. The music... view more... (2003-03-11)
Scientists head to warming Alaska on ice core expedition
The state of Alaska has the dubious distinction of leading the lower 48 in the effects of a warming climate. Small villages are slipping into the sea due to coastal erosion, soggy permafrost is cracking buildings and trapping trucks. view more (2008-04-30)
Ice-Free Arctic Summers Likely Sooner Than Expected
Summers in the Arctic may be ice-free in as few as 30 years, not at the end of the century as previously expected. The updated forecast is the result of a new analysis of computer models coupled with the most recent summer ice measurements. view more (2009-04-03)
Ice study could stop people slip-sliding away
Going out and about in freezing conditions could become safer thanks to fundamental research at the University of Edinburgh into how we slip on ice. view more (2004-12-09)
Remnants of ice age linger in gravity
Researchers have uncovered a large area of low but increasing gravity over North America - the lingering effect of the last ice age when sheets of ice sometimes three kilometres thick covered nearly all of Canada and the northeastern U.S. view more (2007-05-11)
Food shortages threaten Antarctic wildlife
Antarctic whales, seals and penguins could be threatened by food shortages in the Southern Ocean. Numbers of Antarctic krill (Euphausia superba), a shrimp-like crustacean at the heart of the food chain, are declining. The most likely explanation is a dramatic decline in sea-ice. The results are published this week in the journal Nature. view more (2004-11-01)
Impact of Climate Warming on Polar Ice Sheets Confirmed
In the most comprehensive survey ever undertaken of the massive ice sheets covering both Greenland and Antarctica, NASA scientists confirm climate warming is changing how much water remains locked in Earth's largest storehouse of ice and snow. view more (2006-03-09)
Oceanic seesaw links Northern and Southern hemisphere during abrupt climate change
Very large and abrupt changes in temperature recorded over Greenland and across the North Atlantic during the last Ice Age were actually global in extent, according to an international team of researchers led by Cardiff University. view more (2009-02-26)
NASA data show Arctic saw fastest August sea ice retreat on record
Following a record-breaking season of arctic sea ice decline in 2007, NASA scientists have kept a close watch on the 2008 melt season. Although the melt season did not break the record for ice loss, NASA data are showing that for a four-week period in August 2008, sea ice melted faster during that period than ever before. view more (2008-09-29)
A glimpse at the Earth's crust deep below the Atlantic
Long-term variations in volcanism help explain the birth, evolution and death of striking geological features called oceanic core complexes on the ocean floor, says geologist Dr Bram Murton of the National Oceanography Centre, Southampton. view more (2009-11-13)
Global glacier melt continues
Glaciers around the globe continue to melt at high rates. Tentative figures for the year 2007, of the World Glacier Monitoring Service at the University of Zurich, Switzerland, indicate a further loss of average ice thickness of roughly 0.67 meter water equivalent (m w.e.). Some glaciers in the European Alps lost up to 2.5 m w.e. view more (2009-01-29)
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 between two islands. It is another identifiable impact... view more...

Arctic sea ice thinning at record rate
The thickness of sea ice in large parts of the Arctic declined by as much as 19% last winter compared to the previous five winters, according to data from ESA's Envisat satellite. view more (2008-10-29)
Study: Greenland ice sheet larger contributor to sea-level rise
The Greenland ice sheet is melting faster than expected according to a new study led by a University of Alaska Fairbanks researcher and published in the journal Hydrological Processes. view more (2009-06-12)
Bacteria discovery aids food production, water purification
The search for a type of bacteria that creates better ice cream and artificial snow has suddenly become a lot easier, thanks to a discovery by Queen's University biologist Virginia Walker. view more (2006-10-02)
Muscle mass: Scientists identify novel mode of transcriptional regulation during myogenesis
In an upcoming issue of G&D, Drs. Maria Divina Deato and Robert Tjian (HHMI, UC Berkeley) reveal that the formation of an alternative transcriptional core promoter complex directs cell-type specific differentiation during myogenesis. view more (2007-08-20)
Human activity destroys species that the Ice Age could not
Forest clearance and animal overgrazing in the last 5,000 years have destroyed important tree species that had survived even the Ice Age. Dr Mick Frogley, Lecturer in Physical Geography at the University of Sussex, is one of a British research team exploring a site near Lake Ioannina in the Pindus Mountains of northwestern Greece. "Given the... view more... (2002-09-20)
