Deglaciation - Wikipedia
Deglaciation is the transition from full glacial conditions during ice ages, to warm interglacials, characterized by global warming and sea level rise due to change in continental ice volume. [1] Thus, it refers to the retreat of a glacier, an ice sheet or frozen surface layer, and the resulting exposure of the Earth 's surface.

2023年1月5日 · Although Central Europe, Caucasus and Middle East, North Asia, and Western Canada and US are projected to experience widespread deglaciation for the +2°C scenario, our results also reveal where remaining glaciers will be concentrated at the end of this century.
Future emergence of new ecosystems caused by glacial retreat
2023年8月16日 · In deglaciated areas, the emerging ecosystems will be characterized by extreme to mild ecological conditions, offering refuge for cold-adapted species or favouring primary productivity and...
Persistently well-ventilated intermediate-depth ocean through ... - Nature
2020年10月12日 · Intermediate-depth waters in the Atlantic and Pacific Oceans were well equilibrated with the atmosphere through the last deglaciation, according to radiocarbon data from deep-sea corals.
Southern Ocean glacial conditions and their influence on deglacial ...
2023年6月9日 · We discuss the evidence for early initiation of deglaciation in the Southern Ocean, including two proposed mechanisms for how the Southern Hemisphere controls the progression of deglaciation.
Deglaciation - SpringerLink
2014年1月1日 · Deglaciation refers to the uncovering of land and water that was previously covered by ice. The process corresponds to the retreat of the glacier terminus or the ice sheet margin toward its source area (cirque, ice sheet center).
The deglaciation of the Americas during the Last Glacial …
2020年4月1日 · Abstract. This paper reviews current understanding of deglaciation in North, Central and South America from the Last Glacial Maximum to the beginning of the Holocene. Together with paleoclimatic and paleoceanographic data, we compare and contrast the pace of deglaciation and the response of glaciers to major climate events.

THE DEGLACIATION OF THE NORTHERN HEMISPHERE: A Global Perspective. Orbitally induced increase in northern summer insolation after growth of a large ice sheet triggered deglaciation and associated global warming.
