Remote Sensing Photo credit: U.S. It is a joint mission by NASA and the German Aerospace Centre, launched in 2002. These activities demonstrate the value in both GRACE satellite data and MERRA reanalysis data. It is perhaps of concern though that while attitudes internally at NASA may be shifting, those of the Trump administration are not. But the change is still apparent; so, too, is the sense of how the shrinking of the glaciers fits into broader ecosystem changes. Here we examine Landsat images from … Alaska and the Canadian Arctic dominated mass loss, whilst the Southern Andes and High Mountain Asia came third and fourth respectively in terms … Alaska leads the race with over 3019 gigatons lost in total, or 816 million 747s. The area shown is the central portion of the park, extending from the Lake McDonald area (west) to the St. Mary area (east). The increasing rate of glacier mass loss, with eight out of the ten most negative mass balance years recorded after 2010, during a period of retreat indicates alpine glaciers are not approaching equilibrium and retreat will continue to be the dominant terminus response (Pelto, 2019; WGMS, 2020). “On a glacier only 115 acres in size,” Fagre said, “that’s a huge loss.” The change here is slightly more noticeable because of the stark contrast with Upper Grinnell Lake, which has grown in the past few decades as the glacier has retreated. Modeled Climate-Induced Glacier Change in Glacier National Park, 1850–2100. Warm summer temperatures are causing this glacier to lose about 2 to 3 acres per year, and sometimes as much as 10 acres. Most were still there when the national park was established in 1910. Source: NASA Jet Propulsion Laboratory. Muir Glacier in Glacier Bay National Park thinned more than 700 feet in the 23 years between 1980 and 2003. In addition to shrinking in area, Grinnell has rapidly thinned. Lemon Creek Glacier in Juneau is one example of rapid ice loss. Watch an alaskan glacier melt. The glaciers of Alaska are melting and retreating: the chief cause is climate change and the loss of ice is unlikely to slow, according to a new study by U.S. scientists. Johns Hopkins Glacier May 27, 2020 JPEG In southeast Alaska, “glacier change is continuing with no pause or slowdown apparent in the data,” said Chris Larsen. The scientists check snow levels against stakes they’ve inserte… Menagerie Glacier in Glacier Bay National Park, Alaska. A top agenda for the White House is to speed up plans for NASA’s Artemis Program, to land the next people on the Moon by 2024. That’s the year by which this park will purportedly be glacier-free. Today the number of ice bodies is 25. Snow and Ice It is possible for some seasonal snow to persist into August, but most of the blue color in these images is “permanent” snow and ice. In Seward, Alaska, Exit Glacier is melting at an astonishing rate. Planet we live on models often do not capture local change with enough precision and thinned since.
