Climate: Long range Investigation, Mapping, and Prediction, known as CLIMAP, was a major research project of the 1970s and 80s to produce a map of climate conditions during the Last Glacial Maximum. The project was funded by the National Science Foundation as part of the International Decade of Ocean Exploration (1970s) and is based in large ...
The list of periods and events in climate history includes some notable climate events known to paleoclimatology. Knowledge of precise climatic events decreases as the record goes further back in time. The timeline of glaciation covers ice ages specifically, which tend to have their own names for phases, often with different names used for different parts of the world. The names for earlier ...
Throughout Earth 's climate history (Paleoclimate) its climate has fluctuated between two primary states: greenhouse and icehouse Earth. [1] Both climate states last for millions of years and should not be confused with the much smaller glacial and interglacial periods, which occur as alternating phases within an icehouse period (known as an ice age) and tend to last less than 1 million years ...
Cordilleran Ice Sheet. Southern edge of the ice sheet. It extended north along the Pacific coast and covered the Alaska Peninsula. The Cordilleran ice sheet was a major ice sheet that periodically covered large parts of North America during glacial periods over the last ~2.6 million years.
The Last Glacial Maximum (LGM), also referred to as the Last Glacial Coldest Period, [1] was the most recent time during the Last Glacial Period where ice sheets were at their greatest extent 26,000 and 20,000 years ago. [2] Ice sheets covered much of Northern North America, Northern Europe, and Asia and profoundly affected Earth 's climate by ...
Glacial ice is the largest reservoir of fresh water on Earth, holding with ice sheets about 69 percent of the world's freshwater. [ 4 ][ 5 ] The retreat of glaciers has near term impacts on the availability of fresh water for drinking water and irrigation.
Laurentide ice sheet. The maximum extent of glacial ice in the north polar area during the Pleistocene period included the vast Laurentide ice sheet in eastern North America. The Laurentide ice sheet 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 ...
Geologic temperature record. The geologic temperature record are changes in Earth 's environment as determined from geologic evidence on multi-million to billion (10 9) year time scales. The study of past temperatures provides an important paleoenvironmental insight because it is a component of the climate and oceanography of the time.
