Dismal Glacier, British Columbia Prospects Match Name

Landsat image comparison from 1988 and 2015, red arrow indicates 1988 terminus and yellow arrows 2015 terminus. Purple arrows indicate thinning upglacier. Dismal Glacier flows north from Mount Durrand in the Selkirk Range of British Columbia.  It drains from 2500 m to 1950 m and its runoff flows into Downie Creek that is a tributary to the Columbia River and Revelstoke Lake.  This lake is impounded by the BCHydro Revelstoke …

Bionnassay Glacier Terminus Tongue Detaches, Mont Blanc, France

Bionnassay Glacier drains west from Dôme du Goûter and Aiguille de Bionnassay of the Mont Blanc Massif in France. The glacier has a heavily debris covered terminus and has experienced less retreat from 1980-2010 then other Mont Blance glaciers. Bionnassay retreated 200 m (Moreau et al , 2012), while Mer de Glace retreated 500 m in the interval 1998 to 2008. Gardent et al (2014) observed a 25% decline in …

Auyuittuq National Park Ice Cap Downwasting, Baffin Island

Just south of the Penny Ice Cap on Baffin Island in Auyuittuq National Park there are a large number of small ice caps.  We focus on three of these ice caps east of Greenshield Lake.  The region has been experiencing rapid ice loss, with 50 % of the ice cap area lost in the last few decades (Miller et al, 2008).  Miller et al (2008) also observe that these are thin …

Disaggregation of Austria’s Third Largest Glacier, Obersulzbach Kees

The Obersulzbach Glacier, is situated in the uppermost part of the Obersulzbach Valley, which feeds the Salzach River system in Austria. The glacier drains the northeastern flank of Großvenediger. The glacier was the third largest glacier in Austria in the 1980’s, but in the last several decades separated into five distinct sections. Now that it is in five parts, should it be listed as such? Yes, given that the Austrian …

Snow Deficit on Grinnell Ice Cap, Baffin Island, Canada

The Grinnell Ice Cap Is located on the Terra Incognita Peninsula on Baffin Island. The name suggests the reality that this is a not often visited or studied region. Two recent studies have changed our level of knowledge. Way (2015) notes that the ice cap has lost 18% of its area from 1974 to 2013 and that the rate of loss has greatly accelarated and is due to summer warming, …

Langfjordjokulen, Norway Retreat-Thinning

Langfjordjokulen is in the Finnmark region of northern Norway. This is a plateau glacier with a valley glacier extending east toward Langfjordhamm. The Norwegian Water Resources and Energy Directorate has monitored the length change and mass balance of this glacier from 1989-2014. The mean mass balance has been significantly negative averaging -0.7 m/year, with every year being a net loss since 1997. This is no way to sustain a glacier …

Glacier Index of Posts

Glacier Index List Below is a list of the individual glacier posts examining our warming climates impact on each glacier. This represents the first 2.7 years of posts, 180 total posts, 166 different glaciers. I have worked directly on 40. The others are prompted by fine research that I had come across, cited in each post or inquiries from readers and other scientists. I then look at additional often more …

McDonald Glacier, Montana Retreat

McDonald Glacier is in the Mission Range of the Montana southeast of Flathead Lake. It is the largest and one of only two significant glaciers in this range. The glacier is tucked under the north side of McDonald Peak. The glacier was over 1 kilometer long in the 1966 USGS map of the region. By 2005 the glacier has lost 45% of its area, retreating 200 meters on average and …

Snowshoe Peak Glacier Retreat, Yukon

There was the Yukon Gold Rush and then there are a number of surging glaciers in the Yukon. These two have drawn our attention. In Kluane National Park, besides the large surging outlet glaciers draining the St. Elias Mountains (Donjek, Lowell, Kaskawulsh etc.) there are numerous smaller alpine glaciers in ranges just east of the St. Elias. In a recent ice core study in the Eclipse Icefield it was found …

Samudra Tupa Glacier Retreat and Himalaya glacier mass losses

Samudra Tupa Glacier is one of the largest in the Chenab Basin, India. Pink arrow indicates the terminus in a glacier lake and A mark the accumulation zone with the red line indicating the equilibrium line in 1998. In a glacier inventory in the basin by Kulkarni et al (2007) the 466 glaciers in the basin were observed to have lost 21% of their total area from 1962 to 2001. …
