By 2005 the glacier was only 1.5 km (0.93 mi) from reaching Taku Point and blocking Taku Inlet. [60], As recently as 1975 many North Cascade glaciers were advancing due to cooler weather and increased precipitation that occurred from 1944 to 1976. More than 80% of all glacial ice in the northern Andes is concentrated on the highest peaks in small plains of approximately 1 km2 (0.39 sq mi) in size. [128], According to one study, in the years 2002–2019 Greenland lost 4,550 gigaton of ice, 268 gigaton per year, on average. [140] Pine Island Glacier, an Antarctic outflow glacier that flows into the Amundsen Sea. I guess that without having something measurable and quantifiable in front of me that I could judge for myself, my acceptance of climate change would always have been based on other peoples’ opinions. Kilimanjaro, at 5,895 m (19,341 ft), is the highest peak on the continent. [28] The Briksdalsbreen glacier retreated 230 m (750 ft) between 1996 and 2004 with 130 m (430 ft) of that in the last year of that study; the greatest annual retreat recorded on that glacier since studies began there in 1900. It’s truly a shame that this is going on under our watch, and it’s even worse that it’s happening all around the world to virtually all glaciers. Gannett Glacier on the northeast slope of Gannett Peak is the largest single glacier in the Rocky Mountains south of Canada. [157][158][159] The Thwaites Glacier alone, in Western Antarctica is "currently responsible for approximately 4 percent of global sea level rise. The net loss in volume and hence sea level contribution of the Greenland Ice Sheet (GIS) has doubled in recent years from 90 km3 (22 cu mi) per year in 1996 to 220 km3 (53 cu mi) per year in 2005. [118] Similarly, Midre Lovenbreen retreated 200 m (660 ft) between 1977 and 1995. These large, rapidly flowing glaciers situated on steep slopes have been very reactive to small mass-balance changes. Jan Carstensz's 1623 report of glaciers covering the equatorial mountains of New Guinea was originally met with ridicule, but in the early 20th century at least five subranges of the Maoke Mountains (meaning "Snowy Mountains") were indeed still found to be covered with large ice caps. Sakha's glaciers, totaling seventy square kilometers, have shrunk by around 28 percent since 1945 reaching several percent annually in some places, whilst in the Altai and Chukotkan mountains and non-volcanic areas of Kamchatka, the shrinkage is considerably larger. [77] In the Aconcagua River Basin, glacier retreat has resulted in a 20% loss in glacier area, declining from 151 km2 (58 sq mi) to 121 km2 (47 sq mi). The WAIS is bounded by the Ross Ice Shelf, the Ronne Ice Shelf, and outlet glaciers that drain into the Amundsen Sea. Athabasca Glacier: See receding glacier in person. Jökulsárlón is 110 m (360 ft) deep and nearly doubled its size between 1994 and 2004. [5] All are located in mountain ranges, notably the Himalayas; the Alps; the Pyrenees; Rocky Mountains; the Caucasus and Pacific Coast Ranges of North America; the Patagonian Andes in South America; and mountain ranges in New Zealand. If seeing the tragic decline of the incredible glacier doesn’t make you want to do something for the planet, nothing will. Thanks for your reply and consent. [139], Dakshin Gangotri Glacier, a small outlet glacier of the Antarctic ice sheet, receded at an average rate of 0.7 m (2.3 ft) per year from 1983 to 2002. The thinner ice then experienced spreading rifts and breakup. I mean it’s such a nebulous and distant concept that I think I just put it to the back of my mind and ignored it. Thanks. Thirdly, few taller mountains exist in these regions upon which enough cold air exists for the establishment of glaciers. [1] Climate change may cause variations in both temperature and snowfall, resulting in changes in mass balance. No longer. Losing half its volume and retreating more than 1.5 kms, the shrinking glacier has left a moonscape of rocky moraines in its wake. Between the years 1997 and 2001, 68 km (42 mi) long Biafo Glacier thickened 10 to 25 m (33 to 82 ft) mid-glacier, however it did not advance. By 2008 Bossons Glacier had retreated to a point that was 1,400 m (4,600 ft) above sea level. Photographs indicate that the glaciers today are only half the size as when first photographed in the late 1890s. Having had the privilege of visiting the Rockies last year, like you we were concerned about the melting ice at the Columbia Icefields. [143] Thwaites Glacier, which has also shown evidence of thinning, has been referred to as the weak underbelly of the West Antarctic Ice Sheet. [7] Both areas support glacier ice from mountain glaciers, valley glaciers and even smaller icecaps, which are usually located in higher mountainous regions. FIGURE 7: High-angle oblique aerial photograph of Athabasca Glacier taken Aug. 21, 1964 (U.S. Geological Survey) According to research conducted by glacial scientists, the Athabasca Glacier is receding in length and shrinking in volume at an alarming rate. These continuous continental-scale ice sheets, 3 km (1.9 mi) or more in thickness, cap much of the polar and subpolar land masses. [120], In Greenland, glacier retreat has been observed in outlet glaciers, resulting in an increase of the ice flow rate and destabilization of the mass balance of the ice sheet that is their source. The WAIS is classified as a marine-based ice sheet, meaning that its bed lies below sea level and its edges flow into floating ice shelves. The Ward Hunt has lost 90% of its area in the last century. Between 1850 and 1950, the Boulder Glacier on the southeast flank of Mount Baker retreated 8,700 feet (2,700 m). If you’re planning a visit to the Columbia Icefields this summer, why not visit with your environmentalist’s hat on. Figures for Chacaltaya show a loss of 67% of its volume and 40% of its thickness over the same period. [102] and the Idenburg glacier on Ngga Pilimsit dried up in 2003. [56] Tajikistan and neighboring countries of the Pamir Range are highly dependent upon glacial runoff to ensure river flow during droughts and the dry seasons experienced every year. The Athabasca Glacier has retreated 1,500 m (4,900 ft) since the late 19th century. Inland glaciers have had a generally negative mass balance, whereby during the 1990s, maritime glaciers showed a positive mass balance and advanced. [30] Gråfjellsbrea, an outlet glacier of the Folgefonna ice cap, had a retreat of almost 100 m (330 ft). [30] Overall, from 1999 to 2005, Briksdalsbreen retreated 336 metres (1,102 ft). [75] The Northern Patagonian Ice Field lost 93 km2 (36 sq mi) of glacier area during the years between 1945 and 1975, and 174 km2 (67 sq mi) from 1975 to 1996, which indicates that the rate of retreat is increasing. [76] The two major glaciers of the Southern Patagonia Icefield to the north of Moreno, Upsala and Viedma Glacier have retreated 4.6 km (2.9 mi) in 21 years and 1 km (0.62 mi) in 13 years respectively. ", "A Reconciled Estimate of Glacier Contributions to Sea Level Rise: 2003 to 2009", "Forecasting temperate alpine glacier survival from accumulation zone observations", "2013 State of the climate: Mountain glaciers", "Mer de Glace, Glacier Retreat-A Receding Sea", "Glacier des Bossons and Glacier de Taconnaz", Two-thirds of glacier ice in the Alps 'will melt by 2100', Modelling the future evolution of glaciers in the European Alps under the EURO-CORDEX RCM ensemble, "Glacier loss may cost political instability: Expert", "Glaciers melting faster in southeast Turkey, sparking concerns", "The Swiss Glaciers Glaciological Report (Glacier) No. This represents a loss of 8% of the ice field, with all glaciers experiencing significant retreat. It's one of numerous glaciers on the immense Columbia Icefield, which sits astride the … The recent collapse of Wordie Ice Shelf, Prince Gustav Ice Shelf, Mueller Ice Shelf, Jones Ice Shelf, Larsen-A and Larsen-B Ice Shelf on the Antarctic Peninsula has raised awareness of how dynamic ice shelf systems are. [36] Nonetheless, available records do indicate a general retreat of all glaciers in the Altai Mountains with the exception of volcanic glaciers in Kamchatka. The last ice age had much of the world covered with ice, and climate change is part of the natural order of things. [119] In the Novaya Zemlya archipelago north of Russia, research indicates that in 1952 there was 208 km (129 mi) of glacier ice along the coast. I’d love to see your film when eventually if it’s possible to access it online! The likelihood of such events is rising due to the creation and expansion of glacial lakes resulting from glacier retreat. The glacier retreated 1.9 kilometres (1.2 mi) in 33 years. That is not a small boulder – see if you can spot the tiny people next to it. The 50 km2 (19 sq mi) loss in the last 20 years coincides with negative mass balance in the region. The retreat of equatorial glaciers has been documented via maps and photographs covering the period from the late 1800s to nearly the present. [112], Other studies show that between 1960 and 1999, the Devon Ice Cap lost 67 km3 (16 cu mi) of ice, mainly through thinning. Go to the lower lot. Thus, suggests ocean temperature controls ice sheet surface runoff at specific sites. Towns and villages in steep, narrow valleys that are downstream from glacial lakes are at the greatest risk. Thanks to Banff... Hi Lou & Rob, Just found and enjoyed your blog, I clicked on your Facebook link and the first thing I saw was a photo of Railay Beach, wow, what a place, we stayed at the Beach Club a few years ago. There’s always room for doubt with forest fires, hurricanes and floods, but a if a glacier that’s been there for thousands of years suddenly disappears in the space of a few months and years, it’s pretty hard to argue with.
