Revealing glacier flow with satellite images
2015-11-30 02:03:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Frank Paul, a glaciologist at the University of Zurich in Switzerland, has created animations from satellite images of the Karakoram mountain range in Asia to show how its glaciers flow and change. The images of four different regions compress 25 years of glacier changes into just one second, revealing the complex glacier behaviour in the Karakoram. The animations are published today (26 November) in The Cryosphere, an open access journal of the European Geosciences Union (EGU). The new animations...

Lakes expanding 'dangerously' in Everest glacier
2015-11-27 05:54:00| Climate Ark Climate Change & Global Warming Newsfeed
BBC: Lakes that have been forming near Mount Everest could threaten settlements downstream if they overflow. Ponds on the surface of the Khumbu glacier in the Himalayas have expanded and joined together to form larger bodies of water. Climbers need to cross the glacier, including the treacherous Khumbu Icefall, to climb the mighty peak. The accelerated meltdown of glaciers in the region is causing concern against a backdrop of rising global temperatures. Scientists say the warning is the first...

Another Glacier in Greenland is rapidly melting
2015-11-19 14:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Environmental News Network: It's big. It's cold. And it's melting into the world's ocean. It's Zachariae Isstrom, the latest in a string of Greenland glaciers to undergo rapid change in our warming world. A new NASA-funded study published today in the journal Science finds that Zachariae Isstrom broke loose from a glaciologically stable position in 2012 and entered a phase of accelerated retreat. The consequences will be felt for decades to come. The reason? Zachariae Isstrom is big. It drains ice from an area of 35,440 square...

Why massive Greenland glacier is melting from below
2015-11-18 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Christian Science Monitor: A massive glacier in northeast Greenland, named Zachariae Isstrom, has come detached from a stabilizing sill and is rapidly melting into the North Atlantic Ocean, according to a new study. Zachariae Isstrom began "accelerated retreat" in 2012 and is currently melting at a rate of 5 billion tons per year, a team of scientists from NASAs Jet Propulsion Laboratory, the University of Kansas, and the University of California-Irvine published in the journal Science last week. This spells bad news...

Slide of north Greenland glacier quickens, raising sea levels
2015-11-13 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: A glacier in northeast Greenland with enough ice to raise world ocean levels by 50 cms (20 inches) has begun to slide faster toward the sea, extending ice losses to all corners of the vast remote island, a study showed on Thursday. Warmer water temperatures meant the end of the Zachariae Isstrom glacier floated free from a ridge of bedrock below sea level on which it had rested until 2012, according to the U.S. study reported in the journal Science. Without that natural brake, the glacier in the...
