Ice sheets drive atmospheric carbon dioxide levels, inverting previous ice-age theory
In the early 20th century, Milutin Milankovitch, a leading astronomer and climatologist of the time, proposed that the Earth's ice-age cycles could be predicted because they correspond directly with routine changes in the Earth's orbit and its tilt over cycles of tens of thousands of years. view more (2006-07-25)
Boston university researchers develop new model of ice volume change based on Earth's orbit
Through dated geological records scientists have known for decades that variations in the Earth's orbit around the sun — subtle changes in the distance between the two — control ice ages. view more (2006-06-23)
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)
NASA provides new perspectives on the earth's changing ice sheets
It's widely documented that climate change is causing the Greenland and Antarctic ice sheets to shrink. Air temperatures in many parts of the polar regions have increased and waters that surround parts of the ice sheets have warmed up. view more (2006-12-12)
Warm winter also in the Arctic
Central Europe is not the only place where the past, warm winter has caused record temperatures. Unusually mild temperatures also prevented ice formation in the Arctic, specifically in the region around Spitsbergen. view more (2007-03-30)
It's raining pentagons
This week's Nature Materials (09 March 2009) reveals how an international team of scientists led by researchers at the London Centre for Nanotechnology (LCN) at UCL have discovered a novel one dimensional ice chain structure built from pentagons that may prove to be a step toward the development of new materials which can be used to seed clouds... view more...

Man-made soot contributed to warming in Greenland in the early 20th century
New research shows that industrial development in North America between 1850 and 1950 greatly increased the amount of black carbon--commonly known as soot-- that fell on Greenland's glaciers and ice sheets. view more (2007-08-10)
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)
First British Glacial Map to predict future climate change
An academic from the University of Sheffield has produced the first glacial map of Britain, which could allow us to better predict climate change in the future. The map is published in the latest edition of the journal Boreas. view more (2004-11-23)
Movement of Earth's North Magnetic Pole Accelerating Rapidly
After some 400 years of relative stability, Earth's North Magnetic Pole has moved nearly 1,100 kilometers out into the Arctic Ocean during the last century and at its present rate could move from northern Canada to Siberia within the next half-century. view more (2005-12-12)
How will the Arctic sea ice cover develop this summer?
The ice cover in the Arctic Ocean at the end of summer 2008 will lie, with almost 100 per cent probability, below that of the year 2005 - the year with the second lowest sea ice extent ever measured. view more (2008-07-10)
Predetermined winners and losers in the Ice Age extinction game
The Quaternary ice ages caused severe decimation of the European tree flora. Of the diverse pre-Ice Age tree flora only a minority of the genera are still widespread in Europe. Most of the remainder have been lost altogether from the European flora and now only occurs in Asia and/or North America, although some persist as relicts in southern... view more... (2003-07-02)
New Tibetan ice cores missing A-bomb blast
Ice cores drilled last year from the summit of a Himalayan ice field lack the distinctive radioactive signals that mark virtually every other ice core retrieved worldwide. That missing radioactivity, originating as fallout from atmospheric nuclear tests during the 1950s and 1960s, routinely provides researchers with a benchmark against which they... view more...

First large-scale evaluation of iris recognition under way
The National Institute of Standards and Technology (NIST) has announced that it is running the Iris Challenge Evaluation (ICE), the first large-scale evaluation of iris recognition. view more (2005-08-11)
The origin of perennial water-ice at the South Pole of Mars
Thanks to data from ESA's Mars Express mission, combined with models of the Martian climate, scientists can now suggest how the orbit of Mars around the Sun affects the deposition of water ice at the Martian South Pole. view more (2007-07-16)
ODP scientists say no large Northern Hemisphere ice sheets 41 million years ago
New research to test global ice volume approximately 41.6 million years ago shows that ice caps at this time, if they existed at all, would have been small and easily accommodated on Antarctica. view more (2007-08-23)
The MARSIS radar estimates the volume of water in the south pole of Mars
By studying the South Polar region of Mars, the MARSIS (Mars Advanced Radar for Subsurface and Ionospheric Sounding) radar of the Mars Express space probe has enabled the structure of the layered deposits of this region to be elucidated. view more (2007-04-02)
Science From Space
Scientists working at the Bristol Glaciology Centre at the University of Bristol will be staying up all night to watch the lift-off of the largest and most powerful Earth observation satellite ever to be launched by the European Space Agency. The satellite, called ENVISAT, is 25 metres high, ten metres wide and weighs over eight tons. Fully... view more... (2002-02-28)
Research icebreaker 'Polarstern' drifting in Antarctic ice
Since November 27, an ice floe has served as home as well as working place for 55 scientists from 11 nations. The research icebreaker 'Polarstern' of the Alfred Wegener Institute for Polar and Marine Research in Bremerhaven has been tied up firmly to a drifting ice floe in the Antarctic Weddel Sea. view more (2004-12-09)
First direct evidence that human activity is linked to Antarctic Ice Shelf collapse
The first direct evidence linking human activity to the collapse of Antarctic ice shelves is published this week in the Journal of Climate. view more (2006-10-17)
