Data show Antarctic ice stream radiating seismically
A seismologist at Washington University in St. Louis and colleagues at Pennsylvania State University and Newcastle University in the United Kingdom have found seismic signals from a giant river of ice in Antarctica that makes California's earthquake problem seem trivial. view more (2008-06-05)
Past climate of the northern Antarctic Peninsular informs global warming debate
The seriousness of current global warming is underlined by a reconstruction of climate at Maxwell Bay in the South Shetland Islands of the Antarctic Peninsula over approximately the last 14,000 years, which appears to show that the current warming and widespread loss of glacial ice are unprecedented. view more (2009-11-09)
Glaciers Reveal Martian Climate Has Been Recently Active
The prevailing thinking is that Mars is a planet whose active climate has been confined to the distant past. About 3.5 billion years ago, the Red Planet had extensive flowing water and then fell quiet - deadly quiet. It didn't seem the climate had changed much since. view more (2008-04-24)
A warming climate can support glacial ice
New research challenges the generally accepted belief that substantial ice sheets could not have existed on Earth during past super-warm climate events. view more (2008-01-11)
Ecologists use oceanographic data to predict future climate change
Ecologists and oceanographers are attempting to predict the future impacts of climate change by reconstructing the past behavior of Arctic climate and ocean circulation. view more (2008-11-07)
New plant finds in andes foretell of ancient climate change
For the third time in as many years, glaciologist Lonnie Thompson has returned from an Andean ice field in Peru with samples from beds of ancient plants exposed for the first time in perhaps as much as 6,500 years. view more (2005-09-15)
Brain Research To Help In Fight Against Cardiovascular Disease
Scientists at the University of Liverpool, supported by the British Heart Foundation, are studying blood flow in the brain to further medical understanding of cardiovascular disease. view more (2005-03-21)
Scientists Confirm Historic Massive Flood in Climate Change
Scientists from NASA and Columbia University, New York, have used computer modeling to successfully reproduce an abrupt climate change that took place 8,200 years ago. At that time, the beginning of the current warm period, climate changes were caused by a massive flood of freshwater into the North Atlantic Ocean. view more (2006-03-01)
Satellites witness lowest Arctic ice coverage in history
The area covered by sea ice in the Arctic has shrunk to its lowest level this week since satellite measurements began nearly 30 years ago, opening up the Northwest Passage - a long-sought short cut between Europe and Asia that has been historically impassable. view more (2007-09-17)
Arctic Ice More Vulnerable to Sunny Weather, New Study Shows
The shrinking expanse of Arctic sea ice is increasingly vulnerable to summer sunshine, new research concludes. view more (2008-04-22)
Peering under the ice of a collapsing polar coast
Starting this month, a giant NASA DC-8 aircraft loaded with geophysical instruments and scientists will buzz at low level over the coasts of West Antarctica, where ice sheets are collapsing at a pace far beyond what scientists expected a few years ago. view more (2009-10-08)
ASIRAS, a new ESA airborne instrument sees ice for the first time
Making sure that the measurements made by satellites are as accurate as possible has always been a difficult business and this will be especially true for ESA's ice mission CryoSat. However, last week a new instrument, which is set to be the workhorse for validating CryoSat data, was successfully tested from an aircraft over the snow and ice not... view more... (2004-04-08)
The secret of a snake's slither
Snake locomotion may seem simple compared to walking or galloping. But in reality, it's no easy task to move without legs. view more (2009-06-10)
Sunlight has more powerful influence on ocean circulation and climate than North American ice sheets
A study reported in today's issue of Nature disputes a longstanding picture of how ice sheets influence ocean circulation during glacial periods. view more (2008-11-07)
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)
Antarctic Ice Cores - 2002 metres deep as the year 2002 arrives
In the first week of the New Year a team of European scientists reached successfully the depth of 2002 metres of ice at the site of Dome Concordia high on East Antarctica's plateau - one of the most hostile places on the planet. The team, working on a seven-year Antarctic ice core programme to discover the history of the Earth's climate and... view more... (2002-01-15)
German research vessel Polartern discovers abandoned Russian station on ice floe
On August 16, 2004 early in the morning the German research vessel RV Polarstern discovered the remains of the abandoned Russian drifting ice camp North Pole-32 on an ice floe. The position of the floe was 82°16`N - 004°21`W. Three more or less intact barracks (one with antenna), one tent, two damaged barracks, two tractors, three larger... view more... (2004-08-20)
Ice and a slice of climate history
The first 40 million years of Arctic climate history was recovered from beneath the Arctic sea floor yesterday (Monday 23 August). view more (2004-08-24)
Cosmic dust in ice cores sheds light on Earth's past climate
Each year nearly 40,000 tons of cosmic dust fall to Earth from outer space. Now, the first successful chronological study of extraterrestrial dust in Antarctic ice has shown that this amount has remained largely constant over the past 30,000 years, a finding that could help refine efforts to understand the timing and effects of changes in the... view more...

Glaciers not on simple, upward trend of melting
Two of Greenland's largest glaciers shrank dramatically and dumped twice as much ice into the sea during a period of less than a year between 2004 and 2005. And then, less than two years later, they returned to near their previous rates of discharge. view more (2007-02-13)
