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)
Changes in Ocean Circulation Could Lead To Rapid Regional Sea Level Change
One of the major consequences of future ocean circulation changes would be sea level change. This is shown in a new study by scientists from the Potsdam Institute for Climate Impact Research in Germany which was published in the recent issue of "Climate Dynamics". They investigated the scenario of a possible shutdown of the Atlantic overturning... view more... (2005-04-04)
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 governments and industry still unprepared for oil spills 20 years after Exxon Valdez
Two decades after the Exxon Valdez oil spill devastated a vast stretch of the Alaskan coast, governments and industry in the Arctic would be unable to effectively manage a large oil spill, according to a new report by World Wildlife Fund. view more (2009-03-19)
When it comes to sea level changing glaciers, new NASA technique measures up
A NASA-led research team has used satellite data to make the most precise measurements to date of changes in the mass of mountain glaciers in the Gulf of Alaska, a region expected to be a significant contributor to global sea level rise over the next 50-100 years. view more (2008-11-07)
NASA Satellites Measure and Monitor Sea Level
For the first time, NASA has the tools and expertise to understand the rate at which sea level is changing, some of the mechanisms that drive those changes and the effects that sea level change may have worldwide. view more (2005-07-11)
Greenland glaciers dumping ice into Atlantic at faster pace
The amount of ice that Greenland's glaciers dump into the Atlantic Ocean has almost doubled in the last five years because glaciers are moving faster, according to a new Science study. view more (2006-02-17)
Inuit are on the right track
Inuit trails are more than merely means to get from A to B. In reality, they represent a complex social network spanning the Canadian Arctic and are a distinctive aspect of the Inuit cultural identity. And what is remarkable is that the Inuit's vast geographic knowledge has been passed through many generations by oral means, without the use of... view more... (2009-02-05)
Arctic lake sediments show warming, unique ecological changes in recent decades
An analysis of sediment cores indicates that biological and chemical changes occurring at a remote Arctic lake are unprecedented over the past 200,000 years and likely are the result of human-caused climate change, according to a new study led by the University of Colorado at Boulder. view more (2009-10-20)
Lands surface change on Alaska tundra creating longer, warmer summers in Arctic
A gradual lengthening of the snow-free season in Alaska's tundra, and a corresponding northward progression of the growth of shrubs and trees, may be creating a cycle of warmer and longer summers in the Alaskan Arctic. view more (2005-09-23)
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 loss
Increasing amounts of ice mass have been lost from West Antarctica and the Antarctic peninsula over the past ten years, according to research from the University of Bristol and published online this week in Nature Geoscience. view more (2008-01-14)
Study breaks ice on ancient Arctic thaw
A new analysis of ocean-floor sediments collected near the North Pole finds that the Arctic was extremely warm, unusually wet and ice-free the last time massive amounts of greenhouse gases were released into the Earth's atmosphere - a prehistoric period 55 million years ago. view more (2006-08-10)
In the Cornucopia of the European Project of Ice Coring in Antarctica: the oldest Antarctic ice core
On Tuesday 21th of December 2004 a European team involved in Epica (European Project for Ice Coring in Antarctica) reached the drilling depth of 3270.2, which is five meters above the bedrock at Dome C, on the central plateau of the east Antarctic ice sheet. The ice is melting at the bedrock and it has been decided to stop at this depth to avoid... view more... (2005-01-13)
Pollutant haze heats the Arctic
Arctic climate already is known to be particularly prone to global warming caused by industrial and automotive emissions of carbon dioxide and other greenhouse gases. view more (2006-05-11)
Antarctic glacier thinning at alarming rate
The thinning of a gigantic glacier in Antarctica is accelerating, scientists warned today. The Pine Island Glacier in West Antarctica, which is around twice the size of Scotland, is losing ice four times as fast as it was a decade years ago. view more (2009-08-14)
Arctic land and seas account for up to 25 percent of world's carbon sink
In a new study in the journal Ecological Monographs, ecologists estimate that Arctic lands and oceans are responsible for up to 25 percent of the global net sink of atmospheric carbon dioxide. view more (2009-10-15)
The last stage of an arctic odyssey
The French explorer, Gilles Elka'-m, who left North Cape (Norway) in May 2000, has almost completed the seventh and final stage of his 12,000 km solo trek along the rim of the Arctic Ocean, from the Atlantic to the Pacific, on foot, kayak, skis, by sled pulled by himself or by dogs... with help from ESA. The "Arktika" expedition is... view more... (2004-03-30)
Close relationship between past warming and sea-level rise
In a paper in Nature Geoscience, a team from the National Oceanography Centre, Southampton (NOCS), along with colleagues from Tübingen (Germany) and Bristol presents a novel continuous reconstruction of sea level fluctuations over the last 520 thousand years. view more (2009-06-23)
Measuring water from space
Observations from satellites now allow scientists to monitor changes to water levels in the sea, in rivers and lakes, in ice sheets and even under the ground. As the climate changes, this information will be crucial for monitoring its effects and predicting future impacts in different regions. view more (2008-11-13)
