(A 2014 study published in the journal Science by University of Washington scientists used satellite data and numerical modeling to predict that the West Antarctic Ice Sheet, including Thwaites, may collapse in 200 to 1,000 years. For two months in the winter of 2019, Hogan was part of a joint US-UK expedition to the region, a trip that began at Punta Arenas, Chile. New studies show fractures on surface ice and warm seawater melting the ice from underneath. WIRED is where tomorrow is realized. One of the big questions is the speed of the melting, and whether it will reach some kind of tipping point where it will be unable to be reversed if society is able to contain carbon emissions and somehow slow climate change. © 2020 Condé Nast. At the same time, they are seeing troubling signs of increased melting that can still cause a slow rise in sea levels around the globe.

Not only is the Antarctic Ice Sheet growing, NASA admits that the growth is actually reducing sea-level rise. ), Instead, Lhermitte’s model is an attempt to incorporate ice sheet damage into similar global climate models that predict both sea level rise and the future of Antarctica’s glaciers. NBA star's wife 'blindsided' by him holding hands with another woman, Pregnant mom who disappeared on Thanksgiving found dead, Ellen Page comes out as transgender, will be called Elliot, This record-breaking baby is 27 years old — 2 years younger than her mom, Bodybuilder marries sex doll after whirlwind romance, Glacier National Park has reportedly removed and replaced signs that say, "the glaciers will all be gone by the year 2020. Last Updated: 7th August, 2020 16:08 IST Pluto's Glaciers May Be Growing Due To Change In The Dwarf Planet's Seasons: Study When NASA's New Horizon probe flew by Pluto five years ago it was discovered that it has glaciers made of solid methane. This also confirms what I’ve been saying all along. Glacier National Park recently confirmed the changes to CNN but is maintaining a defiant public face. The glacier used to follow a cyclical pattern of advance and retreat. It is also very important to understand that glacier changes are not only … Many factors can speed up or slow down a glacier’s rate of ice loss. One Planet Only Forever at 04:14 AM on 3 February, 2020. The juxtaposition of then and now makes for a dramatic view of our warming planet. Shasta in … The researchers also used special equipment to detect gravitational changes in the glacier that revealed the density of the bedrock below the ice. That’s next to impossible right now, because there are too many other unknown factors to consider, such as the pace of climate change that is warming both the air and water temperature around the glaciers, as well as the movement of ocean currents around Antarctica. “That’s one reason Thwaites has been changing,” he says. And by late Nov 2018, Hudson Bay was already 40% iced up. “You do NOT want your bridge to break, and you do not want to need to predict exactly the conditions that will make it break, so you design with a large safety margin. If Thwaites goes kaput, the resulting catastrophe could raise global sea levels by more than two feet on its own, or by eight feet in combination with melting from nearby glaciers, according to NASA estimates. “We don’t know all the process. Jazz Shaw Posted at 6:31 pm on June 10, 2019. Your California Privacy Rights Sitemap New research shows that Greenland’s glaciers melt faster than expected. “We used measurements of gravitational changes to make a new map of the glacier and seafloor shape,” Porter says. Park spokeswoman Gina … including all the glaciers on Mt. The ‘gone by 2020’ claims were repeated in the New York Times, National Geographic, and other international news sources.” “Almost everywhere, the Park’s specific claims of impending glacier disappearance have been replaced with more nuanced messaging indicating that everyone agrees that the glaciers are melting,” Roots added. Their results show that the damage is creating a positive feedback loop that triggers more damage and faster-moving ice flows. What we have done with this study is look at this damage, the tearing apart of these ice shelves, and what their potential contribution to sea level rise could be.”. And it isn’t just Iceland’s glaciers experiencing expansion. Together, they revealed massive seafloor channels moving warm water to the base of the glacier. We can't ‘design’ Thwaites, so we face these large uncertainties. Thanks for contacting us. See Growing Alaskan glaciers the start of a new Little Ice Age?.. Figure 3: Percentage of shrinking and growing glaciers in 2008–2009, from the 2011 WGMS report. That study, published today in the Proceedings of the National Academy of Sciences, concludes that understanding how the ice field ruptures as it moves across the bedrock is vital to understanding when this collapse might occur. Montana’s Glacier National Park is updating its signs to no longer predict its signature glaciers would be melted by 2020. Categories Archives, Growing glaciers in U.S., Volcanoes - Above water 5 Comments NASA – Largest glacier in Greenland is growing for third year … “The ice shelf slows down the traffic behind. The original estimates of the timing of glacier melt were based on two things: modeled projections of the glaciers’ response to warming, and direct observations of glacial retreat. Perhaps, after so many embarrassments, 2020 will be the year the tide finally turns. This didn’t happen. 14 Oct 08 – “Never before in the history of a research project dating back to 1946 had the Juneau Icefield witnessed the kind of snow buildup that came this year. Mainly, though, it’s because we’re living through an era of green groupthink when even institutions that ought to know better have been overwhelmed by enviro-doom scare narrative. Sept. 2, 2020 Nearly freezing and often an otherworldly shade of blue, glacial lakes form as glaciers melt and retreat. Share on Facebook. And by late Nov 2018, Hudson Bay was already 40% iced up. Jakobshavn's growth did not come as a surprise to scientists. A recent study team from NASA's Jet Propulsion Laboratory in Pasadena, California, determined that water transported to the area around the glacier by a key ocean current has been colder than it was prior to 2016, when the growth began. One Planet Only Forever at 04:14 AM on 3 February, 2020. A group of researchers from the United States and the United Kingdom took advantage of an unusually calm period in Antarctica in January 2019 to explore the two glaciers and the ocean nearby with ships, unmanned submarines, and aircraft to find out what’s happening to the ice and how fast. Scientists say Thwaites and the other glaciers are not likely to collapse in the next century; they are simply too big to fail right now. For several years, scientists have been worried about the retreat and eventual collapse of Thwaites Glacier, a Florida-sized plug that holds back the West Antarctic ice sheet from the Southern Ocean. Glaciers appear to be growing, not melting in recent years at Glacier National Park. Antarctica contains 90 percent of the earth’s ice. !” says reader Vance von Raab. 64,619, This story has been shared 29,333 times. Melting Glaciers Causes Growing Pains for Greenland. After publication of that report, field observations showed glacier melt to be years ahead of the projections, causing scientists in 2010 t… Never put a time limit on your doomsday predictions. The initial scientific fruits of this expedition, part of a five-year $50 million effort called the International Thwaites Glacier Collaboration, are now being published, and the results are worrying. This strongly suggests that glacial retreat is the result of natural causes — the end of the Little Ice Age — rather than of so-called “anthropogenic global warming.”, The National Park Service is not the only institution to have been caught out by the failure of “man-made climate change” to accord with the alarmists’ predicted time schedules. Video of the diorama two years ago. GROWING! I went to the bridge to talk to the captain, and as we were talking this 25-meter cliff emerged out of the gloom.”. 09.14.2020 03:29 PM. By Jessica Chasmar - The Washington Times - Wednesday, January 8, 2020 Montana’s Glacier National Park is updating its signs to no longer predict its signature glaciers would be melted by 2020. Published at: Nov 24 2020 - 12:52 / Updated at: Nov 24 2020 - 12:52. Predicting glacier ice movement is difficult because ice behaves as both a solid and as a liquid, says Penn State University professor of geosciences Richard Alley, who was not affiliated with any of these studies. “We approached Thwaites at night,” Hogan recalls. In 1968 Paul Ehrlich warned in his bestseller “The Population Bomb” that by the end of the ’70s “hundreds of millions of people” would have starved to death. Glacier National Park removes signs saying glaciers would melt by 2020. Its signs will now say: “When they [the glaciers] will completely disappear depends on how and when we act. Glacier National Park quietly removing “Gone by 2020” signs “Rush Limbaugh closed his show today with an article from Glacier National Park (Montana) who says they are taking down their signs warning that the glaciers are melting because they are GROWING!!! Now the vague signs say it's up to us to fix the problem. Glaciers growing because of "global warming," new study claims 24 Aug 06 - See Glaciers growing because of global warming.. This rookie error has been the undoing of charlatans, cultists and false prophets through the ages, from Martin of Tours, who predicted that the world would end by 400, to Harold Camping, who claimed it would happen on Sept. 6, 1994. One thing is consistent: The glaciers in the park are shrinking.”. I meant only the glaciers in the Alps. Figure 2: Percentage of shrinking and growing glaciers in 2008–2009, from the 2011 WGMS report. Two-thirds of glacier ice in the Himalayas will be lost by 2100 if climate targets aren’t met August 3, 2020 11.02am EDT Ann Rowan , University of Sheffield But the point is that we should not be worried that the glaciers on Greenland are growing, because we are all doomed from all the other climate change, global warming, and whatever that is melting all the other glaciers. First, some of the glaciers have expanded, not shrunk, in the last decade. Never put a time limit on your doomsday predictions. Do Not Sell My Personal Information, Your California Privacy Rights The WIRED conversation illuminates how technology is changing every aspect of our lives—from culture to business, science to design. ... 2020. That fear has driven a big push by international teams of researchers to understand what’s going on at Thwaites and nearby Pine Island Glacier. It was similar on a lot of other glaciers too. All rights reserved. At the moment you lose the ice shelf, the glaciers are free to flow and discharge their ice into the ocean.”. The fact we have these big underwater channels going all the way up to the base of the glacier—because they are deeper and larger, you get more of that warm water and would increase the ability to melt.”. Lhermitte thinks his study results mean that Antarctic glaciers need to be closely watched in the coming years for any signs of rapid change that might lead to an environmental catastrophe. “One of the drivers is warm water getting underneath the floating parts and increasing the melting. Not melting. A recent study team from NASA's Jet Propulsion Laboratory in Pasadena, California, determined that water transported to the area around the glacier by a key ocean current has been colder than it was prior to 2016, when the growth began. “They are important because Thwaites is vulnerable to changing quickly under climate change,” Hogan says. Fabiano Ventura is exploring the rooftops of the world to recreate 19th-century photographs of Alpine glaciers. “The understanding of how much and how fast these glaciers are going to change is still unknown,” Lhermitte says. Plenty of green (or proto-green) and other doomsday predictors — have been proved similarly wrong through the ages: from third-century Carthaginian priest Tertullian and 18th-century economist Thomas Malthus (both of whom predicted population growth would outstrip the planet’s ability to feed humanity) to Rachel Carson (who warned of a cancer epidemic due to pesticides); from Peter Wadhams, the Cambridge professor who predicted summer Arctic ice would be gone by 2015 (it’s still there) to the Prince of Wales, who warned in 2009 that there were just “100 months” to save the world from climate change (but then had to extend the deadline, Harold Camping-style, when doomsday failed to materialize). One, authored by Hogan in the journal Cryosphere, detailed the team’s new map of the seafloor at Thwaites using the ship-based sonar readings. “We hope that it allows governments to see where the hot spots might be for glacial lakes growing in the future,” he said. New research shows that Greenland’s glaciers melt faster than expected. The signs, films, flyers and pamphlets published by the National Park Service and U.S. Geological Survey all predict that GNP’s glaciers will melt away by either 2020 or 2030. The segment that once said the glaciers would for sure be gone by 2020 now reads, “When they completely disappear, however, will depend on how and when we act.” The USGS still insists, “The overall picture remains the same, however, and that picture is that the glaciers all continue to retreat.” Given all this, you might be tempted to wonder why any of the supposed experts predicting imminent environmental catastrophe still get taken seriously.

The rest of the mountains will still be available for skiing and bobsledding.) Monitoring on Sept. 6, 2020, revealed that Wedgemount Glacier receded 30 metres between 2019 and 2020, which is almost five metres more than the 10-year average. Glacier National Park has reportedly removed and replaced signs that say, "the glaciers will all be gone by the year 2020." In an email to WIRED, Alley compared the science of studying how Antarctic glaciers move to the process of engineering a bridge. “The ice shelf is getting weaker,” says Stef Lhermitte, an assistant professor of geoscience and remote sensing at the Technical University of Delft in the Netherlands. Part of the reason, I suspect, is that the mainstream media has an insatiable appetite for doomsday predictions (however ridiculous) — and less enthusiasm for stories about how we’re all doing pretty OK. The crew flew over both the glacier and the bay where Thwaites meets the ocean, according to David Porter, an associate scientist at Lamont Doherty Earth Observatory at Columbia University and an author on the second study, also published in the journal Cryosphere. The US/UK team published two scientific papers last week from the 2019 expedition. “They are these large sleeping giants,” Lhermitte says about Thwaites and Pine Island glaciers. Sorry, your blog cannot share posts by email. She declared, “The climate scientists were just joking about the glaciers all melting by 2020, and you were an idiot if you believed them,” she stated. National park ditches signs saying glaciers will be gone by 2020. Not melting. “We start to be curious if they will stay sleeping or awake with large consequences, with sea level rise.”. That’s a harbinger of a coming collapse—and sea level rise. Glacier National Park quietly removing “Gone by 2020” signs “Rush Limbaugh closed his show today with an article from Glacier National Park (Montana) who says they are taking down their signs warning that the glaciers are melting because they are GROWING!!! Quantifying parts of that is important, although remembering that this is still fracture mechanics, and it still might surprise us, one way or the other,” Alley wrote. Growing Alaskan glaciers the start of a new Little Ice Age? Terms of Use Figure 1: Long-term changes in glacier volume adapted from Cogley 2009. New studies show fractures on surface ice and warm seawater melting the ice from underneath. Greenland and the Arctic have also gained ice over the last three years, 45% more than normal in fact. NASA's Oceans Melting Greenland (OMG) project has revealed Greenland’s Jakobshavn Glacier, the island’s biggest, is actually growing, at least at its edge. But since 2008, Franz Josef has been rapidly shrinking. Researchers operating special ship-mounted sonar gear found a series of 25-mile-wide channels in the seafloor that bring warm water to the base of the Thwaites and Pine Island Glaciers. The second paper contained new data from another group that flew over the glacier in a Twin Otter aircraft with ground-penetrating radar that was able to look through the ice. After a five-day crossing to Antarctica on the US research vessel Nathaniel B. Palmer, Hogan arrived at the Thwaites study site and found herself staring at a massive wall of ice. Guides used to be able to lead tourists straight onto the glacier by foot. Antarctic Glaciers Are Growing Unstable Above and Below Water. Do Not Sell My Personal Information. Why France celebrated a well-known pedophile, This story has been shared 64,619 times. When this warm flow meets the place where the glaciers rest on top of the edge of the Antarctic continent—known as the grounding line—the ice underneath the glacier melts and the whole glacier becomes more slippery. These underwater channels are up to 3,280 feet deep and between 12 miles to 25 miles wide, says Porter. Glacier National Park is quietly updating its signs that, based on climate models, erroneously predicted the glaciers would be gone by 2020. by Michael Tennant Now the vague signs say it's up to us to fix the problem. NASA's Oceans Melting Greenland (OMG) project has revealed Greenland’s Jakobshavn Glacier, the island’s biggest, is actually growing, at least at its edge. Representative Ocasio-Cortez has strongly attacked efforts to remove signs in Glacier National Park stating that the glaciers will be gone by 2020. Crater glacier is not typical of a valley glacier but many valley glaciers all over the world are also growing. Park officials have known that the glaciers would still be...

The continued enlargement of Tupper Lake at the base of the glacier was also monitored. If the Antarctic Ice Sheet is growing, wouldn’t that mean that more than 90 percent of the world’s glaciers are growing? Published at: Nov 24 2020 - 12:52 / Updated at: Nov 24 2020 - 12:52.
