Jakobshavn, which is Greenland’s largest glacier and covers roughly 110,000 square kilometers, had been retreating 1.8 miles and thinning 130 feet per year as of 2012, NBC News reported. Study authors and outside scientists think this is temporary. But the last two years it started growing again at about the same rate, according to a study released on Monday, March 25, 2019, in Nature Geoscience. Unusually cold currents in the ocean have caused it and other glaciers situated in western Greenland to grow… The water can get cooler and have effects, but in the long run it is getting warmer and the melting will be worse, he said.Four outside scientists said the study and results make sense.University of Washington ice scientist Ian Joughin, who wasn’t part of the study and predicted such a change seven years ago, said it would be a “grave mistake” to interpret the latest data as contradicting climate change science.What’s happening, Joughin said, is “to a large extent, a temporary blip.
The Jakobshavn glacier around 2012 was retreating about 1.8 miles (3 kilometers) and thinning nearly 130 feet (almost 40 meters) annually. The Jakobshavn glacier, which was once considered one of the fastest-retreating masses of ice and snow on the planet, has reversed its fortunes in recent times and is actually growing back!
The Jakobshavn Glacier, which produced the iceberg that sunk the Titanic, is a 40-mile long, one-mile thick, fast-moving and quickly-thinning glacier in Greenland.. Greenland’s massive ice loss, a tell-tale sign of climate change and warming temperatures, has been particularly rampant in recent years, with the Jakobshavn glacier contributing to a significant chunk of those losses. Downturns do occur in the stock market, but overall the long term trajectory is up. Over the decades the water has been and will be warming from man-made climate change, he said, noting that about 90 percent of the heat trapped by greenhouse gases goes into the oceans.“In the long run we’ll probably have to raise our predictions of sea level rise again,” Willis said.Four outside scientists said the study and results make sense.University of Washington ice scientist Ian Joughin, who wasn’t part of the study and predicted such a change seven years ago, said it would be a “grave mistake” to interpret the latest data as contradicting climate change science.What’s happening, Joughin said, is “to a large extent, a temporary blip. - We kind of got used to a runaway system,” said Geological Survey of Denmark and Greenland ice and climate scientist Jason Box. Over the decades the water has been and will be warming from man-made climate change, he said, noting that about 90 percent of the heat trapped by greenhouse gases goes into the oceans.“In the long run we’ll probably have to raise our predictions of sea level rise again,” Willis said.Think of the ocean temperatures near Greenland like an escalator that’s rising slowly from global warming, Khazendar said. Khazendar and colleagues say this coincides with a flip of the North Atlantic Oscillation – a natural and temporary cooling and warming of parts of the ocean that is like a distant cousin to El Nino in the Pacific.The water in Disko Bay, where Jakobshavn hits the ocean, is about 3.6 degrees cooler (2 degrees Celsius) than a few years ago, study authors said.While this is “good news” on a temporary basis, this is bad news on the long term because it tells scientists that ocean temperature is a bigger player in glacier retreats and advances than previously thought, said NASA climate scientist Josh Willis, a study co-author.
WASHINGTON (AP) — A major Greenland glacier that was one of the fastest shrinking ice and snow masses on Earth is growing again, a new NASA study finds.“That was kind of a surprise.
Jakobshavn Glacier Danish: Jakobshavn Isbræ, also known as Ilulissat Glacier Greenlandic: Sermeq Kujalleq is a large outlet glacier in West Greenland.It is located near the Greenlandic town of Ilulissat (colonial name in Danish: Jakobshavn) and ends at the sea in the Ilulissat Icefjord.. Jakobshavn Glacier drains 6.5% of the Greenland ice sheet and produces around 10% of all Greenland icebergs. Monday, March 25, 2019 Greenland’s Jakobshavn is glacier growing again after shrinking for years and it is probably fine if the growth is temporary, but if not then it will conclusively end up rising the level of seas and oceans and imperil our lives..
