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)
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)
Study Finds Subglacial Water in West Antarctica Considerably More Active Than Previously Observed
The recent discovery of a subglacial water system beneath the West Antarctic ice sheet (WAIS) is causing scientists to rethink the mechanisms that control the flow of ice streams into the Ross Ice Shelf and ultimately into the Southern Ocean, according to a report in the February 15, 2007, issue of Science magazine online. view more (2007-02-16)
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)
NASA Scientist Claims Warmer Ocean Waters Reducing Ice Worldwide
According to a NASA scientist, the pieces to a years-old scientific puzzle have come together to confirm warmer water temperatures are creeping into the Earth's colder areas. Those warm waters are increasing melting and accelerating ice flow in polar areas. view more (2006-03-24)
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)
Warming oceans threaten Antarctic glaciers
Scientists have identified four Antarctic glaciers that pose a threat to future sea levels using satellite observations, according to a study published in the journal Science. view more (2007-03-16)
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)
Greenland melt accelerating, according to CU-Boulder study
The 2007 melt extent on the Greenland ice sheet broke the 2005 summer melt record by 10 percent, making it the largest ever recorded there since satellite measurements began in 1979, according to a University of Colorado at Boulder climate scientist. view more (2007-12-12)
Antarctic ice shelf disintegrating as result of climate change, say scientists
Satellite imagery from the University of Colorado at Boulder's National Snow and Ice Data Center shows a portion of Antarctica's massive Wilkins Ice Shelf has begun to collapse because of rapid climate change in a fast-warming region of the continent. view more (2008-03-26)
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)
Amber specimen captures ancient chemical battle
It appears that chemical warfare has been around a lot longer than poison arrows, mustard gas or nerve weapons - about 100 million years, give or take a little. view more (2007-08-30)
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...

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)
Arctic sea ice declines again in 2006, say University of Colorado researchers
While cool August temperatures prevented sea ice in the Arctic from reaching its lowest summer extent on record, 2006 continued a pattern of sharp annual decreases due to rising temperatures probably caused by greenhouse warming. view more (2006-10-05)
The moon's south pole: Very high resolution, radar images find rocks abundant, but no ice sheets
Using the highest resolution radar-signal images ever made of the moon - images from the National Science Foundation's (NSF) Arecibo Telescope in Arecibo, P.R., and the NSF's Robert C. Byrd Telescope in Green Bank, W.Va. - planetary astronomers have found no evidence for ice in craters at the lunar south pole. view more (2006-10-19)
