The rapid retreat of the Cordilleran ice sheet is a focus of study by glaciologists seeking to understand the difference in patterns of melting in marine-terminating glaciers, glaciers whose margin extends into open water without seafloor contact, and land-terminating glaciers, with a land or seafloor margin, as scientists believe the western ...
The White Chuck Glacier (near Glacier Peak) is a particularly dramatic example. The glacier area shrank from 3.1 km 2 (1.2 sq mi) in 1958 to 0.9 km 2 (0.35 sq mi) by 2002. Between 1850 and 1950, the Boulder Glacier on the southeast flank of Mount Baker retreated 8,700 feet (2,700 m). William Long of the United States Forest Service observed the ...
When the Laurentide ice sheet progressed through the process of deglaciation, it created many new landforms and had various effects of the land. First and foremost, as huge glaciers melt, there is a consequently large volume of meltwater. The volumes of meltwater created many features, including proglacial freshwater lakes, which can be sizable ...
Researchers combed through hundreds of thousands of historical photos of Greenland's coastal glaciers to identify new trends. Greenland glaciers are melting twice as fast as they did in the 2000s ...
The ice would act as a dam as water could not drain through the ice sheet, which in the Wisconsin period covered most of the proglacial river valleys. Numerous small, isolated water bodies formed between the moraine and the ice front. As the ice sheet would continue to melt and recede northward, these ponds combined into proglacial lakes. In ...
The glaciers on the Andes mountain range are melting quickly - at some of the fastest rates on the planet - and the ground beneath them is rising up rapidly too. Scientists discover why the Andes ...
Global warming has increased the speed at which glaciers in Greenland are melting by fivefold over the last 20 years, scientists from the University of Copenhagen said on Friday. Greenland's ice ...
The Laurentide ice sheet (LIS) was a massive sheet of ice that covered millions of square miles, including most of Canada and a large portion of the Northern United States, multiple times during the Quaternary glaciation epochs, from 2.58 million years ago to the present.
