A 2017 study concluded that coastal glaciers and icecaps — what Willis is studying — reached a "tipping point" for ice loss in 1997 and since then have been rapidly deteriorating. The AP is solely responsible for all content. Kangerlussuaq Glacier is one of Greenland’s largest tidewater outlet glaciers, accounting for approximately 5% of all ice discharge from the Greenland ice sheet. “I tend toward the higher number, but I’m hoping for a lower number,” said University of Maryland Baltimore County glaciologist Christopher Shuman, whose family owns property along the coast. If Willis' theory that much of the damage is from the water turns out to be correct, he said, "there's a lot higher potential for Greenland to melt more quickly than we thought." Climate change is eating away at Greenland's glaciers in two ways. The water weakens glaciers and causes icebergs to break loose. "I tend toward the higher number, but I'm hoping for a lower number," said University of Maryland Baltimore County glaciologist Christopher Shuman, whose family owns property along the coast. To measure this, NASA is spending five years crisscrossing the island in a tricked-out 77-year-old DC-3 built for World War II. All Rights Reserved. The answer could be crucial to Earth's future. Now there are new satellite images of flooding in Kangerlussuaq, a key air transportation hub. A 2019 study by Danish climate scientist Ruth Mottram looked at 28 glaciers in Greenland with long-term data. In total the sea has risen by 2.7 centimeters since the 60s and the world's glaciers still contain enough to raise the ocean by another half a meter, which could directly threaten many cities in coastal regions. Other scientists, such as the University of Colorado's Ted Scambos, say Greenland's contribution to sea level rise by 2100 would probably be closer to 1 foot (30 centimeters). Water brings more heat to something frozen faster than air does, as anyone who has ever defrosted a steak under the faucet knows. McCubbin then waits for a tone on his computer that tells him the probe is underwater and measuring temperature and salinity. A study published in 2017 concluded that Greenland's peripheral glaciers and ice caps crossed an irreversible tipping point around 1997, and will continue to melt. (AP Photo/Mstyslav Chernov). They found that Jakobshavn Isbrae lost more than 1.5 trillion tons of ice between 1880-2012, while Kangerlussuaq and Helheim lost 1.4 trillion and 31 billion tons from 1900–2012, respectively. The melt is extremely clear and the glacier is sadly covered in a charcoal sand, which is likely to accelerate its melt. A NASA satellite found that Greenland's ice sheet lost about 255 billion metric tons a year between 2003 and 2016, with the loss rate generally getting worse. And that means seas rising faster and coastal communities being inundated more. Those icebergs eventually melt, adding to the seas. If Willis’ theory that much of the damage is from the water turns out to be correct, he said, “there’s a lot higher potential for Greenland to melt more quickly than we thought.” And that means seas rising faster and coastal communities being inundated more. When all of the flight's five probes start signaling — with a sound McCubbin likens to "a fax machine or an AOL modem" — he and Willis high-five. Like nearly every other glacier on Greenland, the massive Kangerlussuaq is melting. Specifically, he wants to know whether the melting is being caused more by warm air or warm seawater. Meanwhile, pilots Andy Ferguson and Don Watrous bank the plane toward the blue-green spots, looking for the next target and pointing out stunning giant icebergs and signs of glacial retreat over the radio. Warm water provides "a bigger bang for the buck" than air when it comes to melting ice, Willis said. Nearly all are melting, with only one or two that could be considered somewhat stable. The answer could be crucial to Earth’s future. They found that Jakobshavn Isbrae lost more than 1.5 trillion tonnes of ice between 1880-2012, while Kangerlussuaq and Helheim lost 1.4 trillion and 31 billion tonnes from 1900-2012, respectively.

Greenland has been melting faster in the last decade and this summer, it has seen two of the biggest melts on record since 2012. If the water is playing a much bigger role than scientists thought, it could mean seas will be rising faster and higher than expected. 1. Global sea levels have risen 0.55 inches since 2003 due to ice melt in Antarctica and Greenland driven by climate change according to new data measurements from several NASA satellites. As the data is radioed back from one $2,000 probe now deep in the water near Kangerlussuaq in eastern Greenland, it initially looks like the temperature hasn’t changed much over the last year or two, which could be good news. The study, published in Nature Communications on Tuesday, looks at Jakobshavn, Kangerlussuaq, and Helheim glaciers, all of which tumble from the heights of the ice sheet down to sea. The most obvious way is from the warm air above, which has been brutal this summer, with a European heat wave in July working like a hair dryer on the ice. If the water is playing a much bigger role than scientists thought, it could mean seas will be rising faster and higher than expected. Warm water provides “a bigger bang for the buck” than air when it comes to melting ice, Willis said. It’s this deep water that does the major damage. Just how crucial seawater is to melting was illustrated, somewhat paradoxically, by the Jakobshavn glacier, the fast-shrinking glacier on Greenland's more populated west coast.

(AP) — The fields of rippling ice 500 feet below the NASA plane give way to the blue-green of water dotted with irregular chunks of bleached-white ice, some the size of battleships, some as tall as 15-story buildings. Jakobshavn Isbræ and Kangerlussuaq glaciers have gone through “periods of dynamic instability” and are sensitive to small fluctuations in atmosphere or ocean warming, the study said. The ice melt has already contributed more than eight millimetres to global sea levels, the researchers wrote. Some of Greenland's largest outlet glaciers, such as Jakobshavn Isbræ and Kangerlussuaq Glacier, are flowing faster into the ocean. The three largest glaciers in Greenland, capable of lifting the earth's water level by approximately 1.3 meters, may melt down earlier than anticipated time, said researchers. Willis, project manager Ian McCubbin and mechanic Rich Gill drop long, cylindrical probes through a special tube in the floor of the plane, watching as the sensors parachute down and then dive into the chilly water. Estimates of the spatial extent of melt across the Greenland ice sheet (GrIS) were unexceptional for most of the summer (i.e., June, July, August) melt season of 2018. It turns out that the three outlet glaciers—Jakobshavn Isbrae in Western Greenland as well as Helheim and Kangerlussuaq Glacier in Eastern Greenland—have lost ice corresponding to a sea level rise of 8.1 millimetres. If warm water plays a bigger role than scientists suspect, by the year 2100, Greenland alone could cause 3 or 4 feet (more than 1 meter) of sea level rise, Willis said. Vadim Nefedoff/Shutterstock.com. “It’s a little scary,” Willis said as looked down on an area filled with more water than ice. The research, published in Nature Communications, focuses on the “big three” glaciers in Greenland: Jakobshavn Isbræ, Kangerlussuaq Glacier and … In particular, they determined how the Jakobshavn, Helheim and Kangerlussuaq glaciers in Greenland during the late 19th and early 20th century melted at rates that are just as … Facebook hit with antitrust lawsuit from FTC and 48 state attorneys general, New questions over possible vaccine passports for jobs and travel, Election integrity ad campaign urges conservatives to accept 2020 results, In this photo taken on Wednesday, Aug. 14, 2019, NASA scientist Josh Willis looks out of the window after dropping a probe from a plane as they fly above the Kangerlussuaq Glacier, eastern Greenland. That's because 90% of the heat energy from climate change goes into the oceans, Willis said. But that’s just one data point. Greenland's ice sheet and melting glacier into river with tundra aerial view, near Kangerlussuaq, Greenland. Kangerlussuaq Glacier (Greenlandic: Kangerlussuaq, meaning 'large fjord'; old spelling Kangerdlugssuaq) is the largest glacier on the east coast of the Greenland ice sheet. It flows into the head of the Kangerlussuaq Fjord, the second largest fjord in East Greenland. "It's a little scary," Willis said as looked down on an area filled with more water than ice. It will take centuries for all of Greenland’s massive ice sheet to melt, but how fast is the key question. Greenland contains enough ice to make world sea levels rise by 20 feet if it were all to melt. We close the day interviewing local climate change activists @aviaqkl @saschabildorf and @nick_thorleifsen. They found that Jakobshavn Isbrae lost more than 1.5 trillion tonnes of ice between 1880-2012, while Kangerlussuaq and Helheim lost 1.4 trillion … "One glacier retreating looks like carelessness, but 28 retreating is the sign of something going on," Mottram told The Associated Press. In recent years, it suddenly started to grow a bit, probably because of a cooling of waters as a result of a temporary shift in weather and water-current patterns, Willis said. “One glacier retreating looks like carelessness, but 28 retreating is the sign of something going on,” Mottram told The Associated Press. It will take centuries for all of Greenland's massive ice sheet to melt, but how fast is the key question. The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute's Department of Science Education. "Some of them are as big as a city," Willis said. But that's just one data point. In 2018 the Kangerlussuaq ice front reached its most retreated position since observations began in 1932. Kangerlussuaq Glacier is equally struggling, ... Byond temperature, recent findings show increasingly sunny skies could melt ice as could more soot from wildfires driven by climate change. The ice melt has already contributed more than eight millimetres to global sea levels, the researchers wrote. Stay … Willis, project manager Ian McCubbin and mechanic Rich Gill drop long, cylindrical probes through a special tube in the floor of the plane, watching as the sensors parachute down and then dive into the chilly water. 2. That’s because 90% of the heat energy from climate change goes into the oceans, Willis said. Like nearly every other glacier on Greenland, the massive Kangerlussuaq is melting. In a single day this month, it lost a record 13.7 billion tons (12.5 billion metric tons) by one estimate. “Some of them are as big as a city,” Willis said. NASA scientist Josh Willis is now closely studying the phenomenon in hopes of figuring out precisely how global warming is eating away at Greenland’s ice. To measure this, NASA is spending five years crisscrossing the island in a tricked-out 77-year-old DC-3 built for World War II.

Specifically, he wants to know whether the melting is being caused more by warm air or warm seawater. Extreme E heads to the Arctic and the retreating Russell Glacier near Kangerlussuaq in Greenland during its inaugural campaign, raising awareness of the rate at which ice is melting at the poles by racing on land once occupied by the once-mighty glacier, right by its receding snout. Timelapse images of a large calving event at the Helheim Glacier, as published research shows that the three largest glaciers in Greenland -- which hold enough frozen water to lift global sea levels some 1.3 metres -- could melt faster than even the worst-case warming predictions. When University of Georgia ice scientist Tom Mote, who isn't part of this project, started studying Greenland's glaciers in the early 1990s, researchers really didn't think the water was a big factor. In fact, the giant frozen island has seen one of its biggest melts on record this year. The other way is from warm, salty water, some of it from North America's Gulf Stream, nibbling at coastal glaciers from below. Greenland has been melting faster in the last decade and this summer, it has seen two of the biggest melts on record since 2012. In fact, the giant frozen island has seen one of its biggest melts on record this year. They found that Jakobshavn Isbrae lost more than 1.5 trillion tonnes of ice between 1880-2012, while Kangerlussuaq and Helheim lost 1.4 trillion and 31 billion tonnes from 1900–2012, respectively. In a single day this month, it lost a record 13.7 billion tons (12.5 billion metric tons) by one estimate. In general, oceans warm up much more slowly than the air, yet they stay warmer longer. The water weakens glaciers and causes icebergs to break loose. Greenland contains enough ice to make world sea levels rise by 20 feet if it were all to melt. Each year for the past four years, NASA has been looking at all of Greenland, and the numbers overall haven't been quite as comforting. If warm water plays a bigger role than scientists suspect, by the year 2100, Greenland alone could cause 3 or 4 feet (more than 1 meter) of sea level rise, Willis said. In general, oceans warm up much more slowly than the air, yet they stay warmer longer.

"We're definitely watching the ice sheet disappear in front of us.". Like nearly every other glacier on Greenland, the massive Kangerlussuaq is melting. They found that Jakobshavn Isbrae lost more than 1.5 trillion tonnes of ice between 1880-2012, while Kangerlussuaq and Helheim lost 1.4 trillion … What Willis is measuring is the water 660 feet (200 meters) or more below the surface, which is warmer and saltier than the stuff that touches the air. Each year for the past four years, NASA has been looking at all of Greenland, and the numbers overall haven’t been quite as comforting. The other way is from warm, salty water, some of it from North America’s Gulf Stream, nibbling at coastal glaciers from below. Climate change is eating away at Greenland’s glaciers in two ways. NASA scientist Josh Willis is now closely studying the phenomenon in hopes of figuring out precisely how global warming is eating away at Greenland's ice. By viewing our video content, you are accepting the terms of our. A team of researchers based in Denmark and Britain used historical images and a host of other data to estimate … Those icebergs eventually melt, adding to the seas. When University of Georgia ice scientist Tom Mote, who isn’t part of this project, started studying Greenland’s glaciers in the early 1990s, researchers really didn’t think the water was a big factor. From Kangerlussuaq, a 25 km dirt road leads directly to the edge of the Greenland Ice Sheet, passing several viewpoints of glacier tongues along the way. It's this deep water that does the major damage. Water brings more heat to something frozen faster than air does, as anyone who has ever defrosted a steak under the faucet knows. This equals 2,930 ice cubes of 1x1x1 kilometres having melted in the period between 1880 and 2012. Turn on desktop notifications for breaking stories about interest? In fact, the giant frozen island has seen one of its biggest melts on record this year. Now the question is how much and how fast. As the data is radioed back from one $2,000 probe now deep in the water near Kangerlussuaq in eastern Greenland, it initially looks like the temperature hasn't changed much over the last year or two, which could be good news. 3. “We’re definitely watching the ice sheet disappear in front of us.”, In this photo taken on Wednesday, Aug. 14, 2019, icebergs are photographed from the window of an airplane carrying NASA Scientists as they fly on a mission to track melting ice in eastern Greenland. What Willis is measuring is the water 660 feet (200 meters) or more below the surface, which is warmer and saltier than the stuff that touches the air. Now the question is how much and how fast. (AP Photo/Mstyslav Chernov). Researchers found that the Jakobshavn and Kangerlussuaq glaciers actually lost more ice in the late 19th and early 20th centuries, when temperatures were lower, than they are today. ABOARD A NASA RESEARCH PLANE OVER GREENLAND -- The fields of rippling ice 500 feet below the NASA plane give way to the blue-green of water dotted with irregular chunks of bleached-white ice, some the size of battleships, some as tall as 15-story buildings. A 2019 study by Danish climate scientist Ruth Mottram looked at 28 glaciers in Greenland with long-term data. Greenland, Day 4: We travelled to Kangerlussuaq to visit the Russell Glacier. McCubbin then waits for a tone on his computer that tells him the probe is underwater and measuring temperature and salinity. Just how crucial seawater is to melting was illustrated, somewhat paradoxically, by the Jakobshavn glacier, the fast-shrinking glacier on Greenland’s more populated west coast. Surface ice mass balance for the 2017/18 season was below or near the long-term mean (relative to the period 1961-90), consistent with a snow cover that survived late into the spring and average/low surface melting during summer. Other scientists, such as the University of Colorado’s Ted Scambos, say Greenland’s contribution to sea level rise by 2100 would probably be closer to 1 foot (30 centimeters). In fact, the giant frozen island has seen one of its biggest melts on record this year. Like nearly every other glacier on Greenland, the massive Kangerlussuaq is melting. By Dr Alfredo Carpineti 18 … The biggest and most notable impact of these glaciers melting is in the rise of sea level. The most obvious way is from the warm air above, which has been brutal this summer, with a European heat wave in July working like a hair dryer on the ice. Meanwhile, pilots Andy Ferguson and Don Watrous bank the plane toward the blue-green spots, looking for the next target and pointing out stunning giant icebergs and signs of glacial retreat over the radio. The Russell Glacier in Kangerlussuaq and the Eqip Sermia and Sermeq Kujalleq glaciers in Ilulissat are fine places to see calving events. Willis’ project — called Oceans Melting Greenland, or OMG — is showing that it is. A NASA satellite found that Greenland’s ice sheet lost about 255 billion metric tons a year between 2003 and 2016, with the loss rate generally getting worse. Greenland has been a recurring source of headlines in July 2012, with the calving of a new iceberg off the Petermann Glacier and surface melting across nearly all of the Greenland Ice Sheet. In recent years, it suddenly started to grow a bit, probably because of a cooling of waters as a result of a temporary shift in weather and water-current patterns, Willis said.
