The Greenland ice sheet is an ice sheet ... by the ice sheet over the past 12,000 years. ... from 400,000 years ago is consistent with ice losses from ...
A chronology of climatic events of importance for the Last Glacial Period, about the last 120,000 years The Last Glacial Period caused a much lower global sea level.. The Last Glacial Period (LGP), also known as the Last glacial cycle, occurred from the end of the Last Interglacial to the beginning of the Holocene, c. 115,000 – c. 11,700 years ago, and thus corresponds to most of the ...
The Younger Dryas impact hypothesis (YDIH) proposes that the onset of the Younger Dryas (YD) cool period at the end of the Last Glacial Period, around 12,900 years ago was the result of some kind of cosmic event with specific details varying between publications. [1]: Sec 1 The hypothesis is widely rejected by relevant experts.
The retreat of the Laurentide Ice Sheet in Canada led to the formation of moraines and up to 26 proglacial lakes scattered throughout central Canada. The deglaciation occurred from the last glacial maximum (21,000 years ago) to 7000 years ago. Some of the lakes in the southern Ungava Bay area were fully deglaciated c. 6,000 years ago. [5]
NASA scientists in Greenland took an unprecedented look at Cold War history when surveys found an abandoned "city under the ice.". In April, two scientists surveying the Greenland Ice Sheet found ...
[6] [7] Since the end of the Last glacial period about 12,000 years ago, ice sheets have retreated on a global scale, and Earth has been experiencing a relatively warm interglacial period marked by only high-altitude alpine glaciers at most latitudes with larger ice sheet and sea ice at the poles.

The research suggests the critical threshold for the Greenland ice sheet is between 1.7 and 2.3 degrees C of global warming. Bochow said humanity would have 100 years — perhaps more — to cool ...
The Greenland and Antarctic ice sheets are now losing more than three times as much ice a year as they were 30 years ago, according to a new comprehensive international study. Using 50 different ...
