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 between 26,000 and 20,000 years ago. [2]
An artist's impression of the last glacial period at glacial maximum [4]. The LGP is often colloquially referred to as the "last ice age", though the term ice age is not strictly defined, and on a longer geological perspective, the last few million years could be termed a single ice age given the continual presence of ice sheets near both poles.
Glacial history of Minnesota; Glacial period – Interval of time within an ice age that is marked by colder temperatures and glacier advances; Ice age – Period of long-term reduction in temperature of Earth's surface and atmosphere; Last Glacial Period – Period of major glaciations of the Northern Hemisphere (115,000–12,000 years ago)
CLIMAP has been a cornerstone of paleoclimate research and remains the most used sea surface temperature reconstruction of the global ocean during the last glacial maximum (Yin and Battisti 2001), but it has also been persistently controversial. CLIMAP resulted in estimates of global cooling of only 3.0 ± 0.6 °C relative to the modern day ...
The Phanerozoic eon, encompassing the last 542 million years and almost the entire time since the origination of complex multi-cellular life, has more generally been a period of fluctuating temperature between ice ages, such as the current age, and "climate optima", similar to what occurred in the Cretaceous. Roughly 4 such cycles have occurred ...
Studies of the original EPICA core showed that Earth’s climate experienced a 100,000-year cycle of cold glacial periods, or ice ages, interspersed with warmer periods. But this finding didn’t ...
The timing and speed of former glacier melt helps Hall pinpoint, or at least reject, certain hypotheses of the cause of Last Glacial Termination — the period of time where the planet warmed and ...
A glacial period (alternatively glacial or glaciation) is an interval of time (thousands of years) within an ice age that is marked by colder temperatures and glacier advances. Interglacials, on the other hand, are periods of warmer climate between glacial periods. The Last Glacial Period ended about 15,000 years ago. [1]
