Last Glacial Period, not to be confused with the Last Glacial Maximum or Late Glacial Maximum below. (The following events also fall into this period.) 48,000–28,000: Mousterian Pluvial wet in North Africa 26,500–19,000: Last Glacial Maximum, what is often meant in popular usage by "Last Ice Age" 16,000–13,000
The Mesozoic Era [3] is the era of Earth's geological history, lasting from about , comprising the Triassic, Jurassic and Cretaceous Periods.It is characterized by the dominance of gymnosperms such as cycads, ginkgoaceae and araucarian conifers, and of archosaurian reptiles such as the dinosaurs; a hot greenhouse climate; and the tectonic break-up of Pangaea.
The cooling of the 8.2-kiloyear event was a temporary feature, but the sea-level rise of the meltwater pulse was permanent. In 2003, the Office of Net Assessment (ONA) at the United States Department of Defense was commissioned to produce a study on the likely and potential effects of modern climate change. [ 28 ]
Bølling oscillation interstadial (warm and moist period) between the Oldest Dryas and Older Dryas stadials (cool periods) at the end of the Last glacial period. In places where the Older Dryas was not seen, it is known as the Bølling–Allerød warming. c.12,340 BC: c.11,140 BC: Cemetery 117: site of the world's first known battle/war. c ...
Global average temperatures show that the Little Ice Age was not a distinct planet-wide period but a regional phenomenon occurring near the end of a long temperature decline that preceded recent global warming. [1] The Little Ice Age (LIA) was a period of regional cooling, particularly pronounced in the North Atlantic region. [2]
The cooling trend continued in the Miocene, with relatively short warmer periods. When South America became attached to North America creating the Isthmus of Panama around 2.8 million years ago , the Arctic region cooled due to the strengthening of the Humboldt and Gulf Stream currents, [ 35 ] eventually leading to the glaciations of the ...
The cooling period is reproduced by current (1999 on) global climate models that include the physical effects of sulfate aerosols, and there is now general agreement that aerosol effects were the dominant cause of the mid-20th century cooling. At the time there were two physical mechanisms that were most frequently advanced to cause cooling ...
Global cooling through volcanism is the sum of the influence of the global dimming and the influence of the high albedo of the deposited ash layer. [108] The lower snow line and its higher albedo might prolong this cooling period. [109]
