New Greenland ice melt fuels sea level rise concerns

Stability in the rapidly changing Arctic is a rarity. Yet for years researchers believed the glaciers in the frigid northeast section of Greenland, which connect to the interior of the country’s massive ice sheet, were……

Scientists discover vast reservoir under Greenland that may hold clues to explain shrinking glaciers

Scientists have discovered a vast reservoir of fresh water captured in layers of old snow buried near the surface of Greenland’s vast ice sheet. The reservoir, located in southeastern Greenland, is similar to a subsurface aquifer found on land. Its…  …

Massive canyon revealed under Greenland ice sheet

NASA announced on Thursday that a massive canyon that has been unknown for all of human history has been found under a mile of ice in Greenland. An airborne research project known as Operation IceBridge discovered the canyon via ice-penetrating radar signals. Under the multimillion-year-old sheet of ice lies a…

Valley as deep as the Grand Canyon lies beneath Greenland

A huge canyon twice the size of the longest river in Britain and as deep as the Grand Canyon lies beneath the ice sheet in Greenland, scientists said Thursday. Prior to the establishment of the ice sheet some four million years ago, the canyon is believed to have been a…

NASA GROVER solar-powered robot takes a test drive in harsh Greenland climate

NASA has just completed a field test of its new solar-powered polar rover. The new robot named GROVER, which stands for Goddard Remotely Operated Vehicle for Exploration and Research, has passed an extreme environment test in the harshest part of Greenland…  …

Even mild global warming could completely melt Greenland’s ice cap

The Greenland icesheet is more sensitive to global warming than thought, for just a relatively small — but very long term — temperature rise would melt it completely, according to a study published on Sunday. Previous research has suggested it would need warming of at least 3.1 degrees Celsius (5.6…
