Cold Water Currently Slowing Fastest Greenland Glacier
NASA research shows that Jakobshavn Glacier, which has been Greenland’s fastest-flowing and fastest-thinning glacier for the last 20 years, has made an unexpected about-face. Jakobshavn is now flowing more slowly, thickening, and advancing toward the ocean instead of retreating farther inland. The glacier is still adding to global sea level rise - it continues to lose more ice to the ocean than it gains from snow accumulation - but at a slower rate...

NASA’s Greenland Mission Still Surprises in Year Four
Only seven months after NASA’s Oceans Melting Greenland (OMG) mission wrapped its last field campaign on the world’s largest island, an OMG crew is back in Greenland to collect more data. With two or three field projects a year since 2016, no wonder OMG has made the most comprehensive measurements yet of how ocean water lapping at the undersides of Greenland’s melting glaciers affects them. All that data has answered a lot of existing questions - and it’s raised plenty of new ones...

The Biggest Threat to Greenland’s Glaciers Lies Deeper in the Ocean Than Expected
This summer, a chunk of ice the size of lower Manhattan broke off of a glacier in Eastern Greenland. It contained 10 billion tons of ice, making the video of the event an insanely shareable capsule of climate change dread. But for NASA scientists, the spectacle created by these massive calving events is really just the final step in a far more worrisome — and less visible — process...

Narwhals Are Helping NASA Understand Melting Ice and Rising Seas
Greenland’s ice cap holds beneath it 10 percent of the earth’s freshwater, enough to raise global sea levels by 20 feet. While there’s no doubt it is melting, scientists have little certainty about exactly what’s happening inside this 10,000-year-old ice roughly three times the size of Texas. Last winter was the warmest on record in the Arctic, and as Greenland heats up, understanding this glaciate has become essential to navigating our future...

Greenland’s Thinning Ice
With temperatures around the world climbing, melt waters from the continental ice sheets of Greenland and Antarctica are raising sea levels. Those ice sheets are melting from both above and below. Much of the ice lost from ice sheets comes from a process called calving where ice erodes, breaks off, and flows rapidly into the ocean. A large volume of ice is also lost from ice sheets melting on their surfaces...

Sun and sky, snow and ice - Reflections at the top of the world
It was 11:30 in the morning and GLISTIN-A instrument engineer Ron Muellerschoen and I were in northern Greenland at the Thule Air Base pier looking over the frozen Wolstenholme Bay. We’d been talking about the time Ron was wearing shorts here during the summer, but today it was the typical -22 Fahrenheit (-30 Celsius.) And even though over the past week we’d somehow gotten used to the cold and I was wearing a big parka, my legs were starting to get cold after walking for an hour. So we decided to head back...

Science Torpedoes Reveal How Greenland Is Melting From Below
If the climate keeps warming the way it has, Greenland may finally live up to its name (which was probably bestowed on it by some colorblind viking). The island’s glacier-crusted surface is melting, and a lot of this is from balmier atmospheric temperatures. But as the saying goes, that’s just the tip of the iceberg. The oceans are becoming more tepid as well, and that warmer water is causing the glaciers to thaw from below...

OMG: How fast are oceans melting Greenland?
We know more about the moon and other planets than we do some places on our home planet. Remote parts of the world ocean remain uncharted, especially in the polar regions, especially under areas that are seasonally covered with ice and especially near jagged coastlines that are difficult to access by boat. Yet, as global warming forces glaciers in places like Greenland to melt into the ocean, causing increased sea level rise, understanding these remote places has become more and more important...
