Similarly, the possible snowball Earth of the Precambrian's Cryogenian between 580 and 850 million years ago (and which itself had a number of distinct episodes) could be related to the rise of more advanced multicellular animal life and life's colonisation of the land.
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 ]
Timeline of glaciation. Appearance. Climate history over the past 500 million years, with the last three major ice ages indicated, Andean-Saharan (450 Ma), Karoo (300 Ma) and Late Cenozoic. A less severe cold period or ice age is shown during the Jurassic - Cretaceous (150 Ma). There have been five or six major ice ages in the history of Earth ...
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 ...
Late Cenozoic Ice Age, the geologic period of the last 33.9 million years. Little Ice Age, a period of relative cold in certain regions from roughly 1450–1480. Pleistocene, a geologic epoch, often colloquially referred to as the "Ice Age", that includes the world's most recent repeated glaciations (2,580,000 to 11,700 years ago) Plio ...
The Pleistocene (/ ˈplaɪstəˌsiːn, - stoʊ -/ PLY-stə-seen, -stoh-; [ 5 ][ 6 ] often referred to colloquially as the Ice Age) is the geological epoch that lasted from c.2.58 million to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International ...
The shape of Earth's orbit around the Sun affects the Earth's climate. Over a 100,000 year cycle, Earth oscillates between having a circular orbit to having a more elliptical orbit. [ 24 ] From 2.58 million years ago to about 1.73 million ± 50,000 years ago, the degree of axial tilt was the main cause of glacial and interglacial periods.
199.6. Triassic–Jurassic extinction event, causes as yet unclear. 66. Perhaps 30,000 years of volcanic activity form the Deccan Traps in India, or a large meteor impact. 66. Cretaceous–Paleogene boundary and Cretaceous–Paleogene extinction event, extinction of dinosaurs. 55.8. Paleocene–Eocene Thermal Maximum. 53.7.
