NASA and USGS are using a real-time ice sheet viewing process in order to study the factors that influence the movement of glaciers and ice sheets towards the sea.
The mystery behind Greenland’s icy history, where it was ice-free for 280,000 years, could help in research for climate change survival. However, mapping the history of the ice growth and shrinkage proves to be a remarkably difficult task. While researchers are digging deeper into the past, the ice narrative is becoming even more tangled.
Greenland ice melted on Monday at such a catastrophic speed that scientists could hardly believe it. It was such an the "extreme melt event" that experts had to check if they were making a mistake.
Following especially warm summers and increased icemelt, Greenland's ice sheet appears to waterlogged and unable to to buffer its contribution to rising sea levels.
As part of their ongoing "ScienceCasts" video series, Science@NASA reminds just how closely experts from around the world have been keeping a wary eye on Greenland's ice sheet. The result has been a mountain of research all showing the same thing: under the thinning of ice is a whole lot of nothing, and that's not good news.
The answer to scientists' questions about why Greenland was cooler than the rest of North America through the early 1990s, but is warming now--may have new solar-connected connections.
Just yesterday, Nature World News reported on Greenland's mysteriously vanishing lakes, which can drain entirely in just a matter of a few hours. But now, a subsequent study is saying that while warming temperatures have created more of these supraglacial lakes, they are not likely to worsen Greenland's contribution to sea level rise.
Though many recent media reports note that the Earth's warming climate is to blame for Greenland's glacier melt - in addition to other melting ice forms like those in Antarctica - a new study shows that oceans may contribute in large part to these glaciers' demise.
Researchers have found evidence that ash from forest fires in the Northern Hemisphere is finding its way into snow-build across Greenland, causing vulnerability and melt of the Greenland ice sheet - which scientists once thought was caused by global climate change alone.
Greenland is losing ice from part of its territory at an accelerating rate - faster than previously thought - suggesting that the icecap is growing increasingly unstable, according to a study in Nature Climate Change.
NASA is on a mission to find out what lies beneath the two-mile thick ice sheets in Greenland by sending in a remote-controlled, solar-powered robot called Grover.
