The northern part of the Greenland ice sheet experienced extreme snowmelt during the summer of 2008, with large portions of the area subject to record melting days, according to Dr. Marco Tedesco, Assistant Professor of Earth & Atmospheric Sciences at The City College of New York (CCNY), and colleagues.

Researchers from TU Delft joined forces with the Center for Space Research (CSR) in Austin, Texas, USA, to develop a method for creating an accurate picture of Greenland’s shrinking ice cap.

Why is Greenland covered in ice?

Only changes in carbon dioxide levels are able to explain the transition from the mostly ice-free Greenland of three million years ago, to the ice-covered Greenland of today

Rewriting Greenland's immigration history

Thirty-six-year-old Professor Eske Willerslev, University of Copenhagen, and his team of fossil DNA researchers have done it a couple of times before: rewritten world history. Most recently two months ago when he and his team discovered that the ancestors of the North American Indians were the first people to populate America, and that they came to the country more than 1,000 years earlier than originally assumed.

Researchers warm up to melt's role in Greenland ice loss

In July 2006, researchers afloat in a dinghy on a mile-wide glacial lake in Greenland studied features of the lake and ice 40 feet below. Ten days later the entire contents of the lake emptied through a crack in the ice with a force equaling the pummeling water of Niagara Falls. The entire process only took 90 minutes.

Lakes of meltwater can crack Greenland's ice, contribute to ice sheet flow

Researchers from the Woods Hole Oceanographic Institution (WHOI) and the University of Washington (UW) have for the first time documented the sudden and complete drainage of a lake of meltwater from the top of the Greenland ice sheet to its base.

Antarctic ice loss speeds up, nearly matches Greenland loss

Ice loss in Antarctica increased by 75 percent in the last 10 years due to a speed-up in the flow of its glaciers and is now nearly as great as that observed in Greenland, according to a new, comprehensive study by UC Irvine and NASA scientists.

True North Gems Seeks Alternative to Myanmar “Blood” Rubies

True North Gems, b developing ruby and sapphire in Greenland, can play a role in breaking the dominance of governments such as Myanmar’s, the world’s largest supplier of rubies and sapphire.

Greenland snow melting hit record high in high places

A new NASA-supported study reports that 2007 marked an overall rise in the melting trend over the entire Greenland ice sheet and, remarkably, melting in high-altitude areas was greater than ever at 150 percent more than average. In fact, the amount of snow that has melted this year over Greenland could cover the surface size of the U.S. more than twice.

Glaciers, ice caps to dominate sea level rise this century

Ice loss from glaciers and ice caps is expected to cause more global sea rise during this century than the massive Greenland and Antarctic ice sheets, according to a new University of Colorado at Boulder study.

Earth was warmer than previously believed

A team of international researchers has collected the oldest ever recovered DNA samples and used them to show that Greenland was much warmer at some point during the last Ice Age than most people have believed.
