glacier national park glaciers growing

As scientists continue to warn about melting glaciers in the Antarctic, one key glacier in Greenland is growing again, NASA says. Funding for these webcams comes, in part, from the Glacier National Park Conservancy. In Glacier National Park (GNP), USGS scientists define glaciers according to the commonly accepted guideline in which a body of ice has an area of at least 0.1 km2 (100,000 m2), or about 25 acres. This story has been shared 78,524 times. After publication of that report, field observations showed glacier melt to be years ahead of the projections, causing scientists in 2010 to revise their “end date” to 2020. For more than 10 years, Glacier National Park in Montana had signs that said all of its namesake glaciers would be gone by 2020. A 2003 report was based on modeling a scenario of doubling pre-industrial atmospheric CO2 levels by 2030, which would have melted the park’s major glaciers – and presumably the minor ones, too – by 2030. The death throes of glaciers are an urgent research topic, as streamflow, water supplies, aquatic habitat, and albedo feedback all hinge on the presence of glaciers. This is just one of many examples where interpretive signs in the national parks are updated to reflect emerging science. Furthermore, Sperry Glacier is monitored in size and volume twice a year. In late summer when the glaciers are most visible, satellites can capture images to measure the areas of glaciers. Alas, it isn’t. Accessed June 13, 2016. But the glaciers are growing. The signs of climate change may be most visceral on a local level, but preserving what remains of the glaciers requires dramatically scaling back greenhouse gas emissions around the world. Can shearing of Thwaites glacier slow or stop if humans control greenhouse gas emissions? This story appears to have been triggered when the Park Service changed three signs about projected dates when the glaciers might melt completely. Florentine noted that she and other scientists, comparing measurements from benchmark glaciers in the Northern Rockies, Cascades, and Alaska, found all the glaciers to be losing mass, even though they are at different elevations, latitudes, and climate regimes. Caitlyn Florentine, a glaciologist with the U.S. Geological Survey’s Northern Rocky Mountain Science Center, is one of several scientists charged with keeping an eye on the park’s glaciers. Scientists predict that, by the year 2030, the glaciers that give their name to Glacier National Park will be gone. May 30, 2019. National Park Service (2016) Glacier National Park: Glaciers/Glacial Features. When asked if these assertions are true, Florentine was resolute: “No,” she said, shaking her head. Both glaciers have gotten progressively smaller, and their overall footprints shrank by 8.4% and 5.8% respectively, in the 10-year period between 2005 and 2015. Thus, new research continues to shed light on the subject. She described the methods used to keep track of the glaciers, from analysis of aerial photography and satellite imagery, to boots-on-the-ice measurements of glacial ice volume. These signs said that the glaciers could be gone by 2020. Roots, J.D., Ph.D., Founder, Lysander Spooner University. An arête where three or more glaciers meet to form a peak is called a horn. The U.S. Geological Survey spells it out in plain language: “Despite occasional big winters or frigid weeks that occur, the glaciers of GNP, like most glaciers worldwide, are melting as long-term average temperatures increase.”. Titled “Glacier National Park Quietly Removes Its ‘Gone by 2020′ Signs,” Roots’ describes a scramble by federal park officials to hide or … Florentine summarized the findings as an “overall, consistent trend of mass loss” which she described as “pretty striking, considering that the benchmark glaciers are in such different climate settings.”, Echoing USGS, the National Park Service is unequivocal on its website: “the park’s glaciers are all getting smaller,” explains the park’s webpage about glaciers. Climate variability sometimes causes more snow to accumulate on glaciers, causing them to grow. The glaciers at Glacier National Park probably formed after the Holocene Climatic Optimum and reached their maximum extent in the mid-1800’s toward the end of the Little Ice Age. Despite recent cold winters, warmer-than-average summer temperatures have been erasing all the wintertime gains, and then some. 69,149, This story has been shared 39,086 times. The data include scientific information for the 37 named glaciers in Glacier National Park and two glaciers on U.S. Forest Service land. Visit Glacier virtually with the park's webcams! Perito Moreno is one of the only glaciers in the world that is growing instead of shrinking. The history of glaciation within current Glacier National Park boundaries spans centuries of glacial growth and recession, carving the features we see today. By also exploring its cultural and economic history, the human impact is observed, including what the future might hold for this park as its glaciers quickly vanish. Enter email for instant 15% discount code & free shipping. Your California Privacy Rights The signs have been updated to say, “When they will completely disappear, however, depends on how and when we act.”, Another sign that used to have the 2020 date now reads, “Some glaciers melt faster than others, but one thing is consistent: the glaciers in the park are shrinking.”. Glacier National Park is replacing signs predicting that its glaciers will be “gone by 2020.” Sharp-eyed visitors have noticed that far from disappearing by 2020, some of them have actually increased in size, and 29 of the glaciers in the Montana park remain stubbornly unmelted, despite “climate change.” 78,524, This story has been shared 69,149 times. St. Mary, Montana. You can visit their website to learn more about the projects they fund throughout Glacier. Yet the mass trend in the northern Rockies, where Glacier National Park is located, and in nearly all mountain ranges in the world is on a steady decline. Post was not sent - check your email addresses! Rebutting myths about climate change is an endless game of whack-a-mole. The residual parts of the glaciers are higher, more shaded, and receive more snow deposition from avalanches and windblown snow. As the myth was repeated across multiple denier websites, the situation was described as the Park Service’s being “forced to admit” it had been wrong and “scrambling to remove the signs without their visitors noticing.”. Since 1895, NOAA data show the two counties that comprise Glacier National Park have warmed nearly 3 degrees F, a trend that is taking a heavy toll on the glaciers. The new signs reflect as much, reading: “When they will completely disappear depends on how and when we act. Climate Alarmists Meltdown Over Glacier National Park (Except When They’re Growing) A blog published earlier this month by Roger Roots, an attorney, reveals overheated desperation of a different sort than we tend to hear about in the mainstream media. If that were actually happening, it would be welcome news, and as the blog author hints, it would indeed be newsworthy. Email. “That’s why we turn to science.” Florentine described the work of the USGS as “systematic and reproducible,” a far cry from snapping a photo from the side of the road. WEST GLACIER, Mont. This 2020 date was then put on signs in the park, educating visitors about the observations of rapid ice loss resulting from global warming. That’s the case with this myth, too. “It’s measurement-intensive,” she said in a video call from her West Glacier office. Because of these factors, these glacier remnants appear more capable of withstanding higher temperatures, compared to the thinner, lower-elevation parts of the glaciers that underwent rapid melt. The evidence presented is a single, blurry photograph snapped from an overlook along a popular park road, and a video that compares a cell phone photo to an image of Grinnell Glacier on a park recycling bin. Accessed June 13, 2016. Glacier National Park in the U.S. state of Montana is filled with deep glacial valleys and sharp arêtes. “It appears that the National Park Service is trying to hide the fact that the glaciers are growing!”. The cumulative dataset spanning 50 years of glacier monitoring was released in 2017 and is freely available to the public. Were it true that Jackson glacier had grown by 30% since 2009, the glacier would be larger now than it was in the 1990s. We've received your submission. Jakobshavn Glacier in western Greenland is notorious for being the world’s fastest-moving glacier. Sitemap Sorry, your blog cannot share posts by email. The National Park Service has quietly removed all the signs put up by the Obama administration that told visitors that the glaciers would “all be gone” by the year 2020 due to global warming… because… it’s 2019, and the glaciers are all still there and have been growing. Glaciers are receding rapidly all around the world: in the Himalayas, Greenland, the Alps, Africa, South America, and Antarctica. Privacy Notice While the projected melting date has been pushed forward, the glaciers are far from being out of harm’s way, park reps say. – Going-to-the-Sun Road, the mountain pass that connects the east and west sides of Montana's Glacier National Park, is free of snow and ahead of schedule. On average, the glaciers have reduced by 39 percent and only 26 glaciers are now larger than 25 acres, which is used as a guideline for deciding if bodies of ice are large enough to be considered glaciers.

Park officials have known that the glaciers would still be intact come 2020 since 2017, when they learned that the US Geological Survey forecast … Glaciers were present within current Glacier National Park boundaries as early as 7,000 years ago but may have survived an early Holocene warm period (Carrara, 1989), making them much older. Your Ad Choices Fortunately, the topic is getting due attention from legitimate scientists. (Some signs even tell visitors that the glaciers may be gone by 2020.) After encountering several social media references that glaciers are growing in my home state of Montana, I dug in to find the origin of the myth, and check in with scientists for an update on the status of Glacier National Park’s namesake features. Glacier was established as a national park on May 11, 1910, America’s 10 th national park. Official Park literature claims that all glaciers in GNP are predicted to melt away by the year 2030. Accessed June 13, 2016. © 2020 Yale Climate Connections | Created by Constructive, Inuit activist Sheila Watt-Cloutier on the cultural value of ice and snow. 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. 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. What, then, is the future of the million-acre national park … While there are several great hotels, cabins and camp sites inside the park, the best place to … (Some signs even tell visitors that the glaciers may be gone by 2020.) Glaciers are “dynamic and flowing landforms,” explained Florentine, and new understanding of the intricacies of glacier retreat can help clarify why the remaining glaciers are more persistent than once thought. The page about climate change bears a stark headline: “This rapid rate of warming is melting the park’s glaciers, increasing the severity and likelihood of wildfires, and shifting wildlife habitat.” The caption on a graph of CO2 and temperature over the past 400,000 years leaves no doubt about the cause of warming: “In the past century, human activities have emitted a significant amount of CO2, which is causing the Earth to heat up – and glaciers to melt – at an alarming rate.”, One element of deliberate misinformation is that it often contains a grain of truth. The site that made these claims turns out to be mostly that of a single person who writes a blog espousing libertarian themes, while crediting himself as “the only research institution challenging the government’s Glacier Park climate hysteria.”, The blog post goes on to chastise the media for ignoring its assertions: “No mainstream news outlet has done any meaningful reporting regarding the apparent stabilization and recovery of the glaciers in GNP over the past decade.”.
