The Holocene glacial retreat is a geographical phenomenon that involved the global retreat of glaciers (deglaciation) that previously had advanced during the Last Glacial Maximum. Ice sheet retreat initiated ca. 19,000 years ago and accelerated after ca. 15,000 years ago.
All the glaciers in Turkey are in retreat and glaciers have been developing proglacial lakes at their terminal ends as the glaciers thin and retreat. [ 61 ] [ 62 ] Between the 1970s and 2013, the glaciers in Turkey lost half their area, going from 25 km 2 (9.7 sq mi) in the 1970s to 10.85 km 2 (4.19 sq mi) in 2013.
A glacial terminus Satellite view of changing glacier termini in the Bhutan-Himalaya, showing glacial lakes formed by the retreating termini on the surface of the debris-covered glaciers over the last several decades. A glacier terminus, toe, or snout, is the end of a glacier at any given point in time.
Studying exposed landforms can also inform the understanding of the present and near future as glaciers all over the world retreat in the current period of climate change. [26] In general, recently deglacialized landscapes are inherently unstable and will tend to move towards an equilibrium.
The retreating glaciers of the last ice age, both depressed the terrain with their mass and provided a source of meltwater that was confined against the ice mass. Lake Algonquin is an example of a proglacial lake that existed in east-central North America at the time of the last ice age .
A century later glacier retreat has opened a multi-armed bay more than 30 miles long. The tidewater glacier has divided into three independent glaciers, Yahtse, Tsaa and Guyot Glacier. Other examples of glaciers currently in the retreat phase are South Sawyer and Sawyer Glaciers in Alaska, retreating 2.1 and 2.3 km respectively from 1961 to 2005.
Kettle – Depression or hole in an outwash plain formed by retreating glaciers or draining floodwaters; Moraine – Glacially formed accumulation of debris Rogen moraine, also known as Ribbed moraines – Landform of ridges deposited by a glacier or ice sheet transverse to ice flow
Since the glaciation of the Little Ice Age, Earth has lost more than 50% of its glaciers. This along with the current increase in retreating glaciers caused by climate change has created a shift from frozen to liquid water, increasing the extent and volume of glacial lakes around the world. Most glacial lakes present today can be found in Asia ...
