Little Ice Age: Various dates between 1250 and 1550 or later are held to mark the start of the Little ice age, ending at equally varied dates around 1850 1460–1550 Spörer Minimum cold; 1656–1715 Maunder Minimum low sunspot activity; 1790–1830 Dalton Minimum low sunspot activity, cold
Shows the pattern of temperature and ice volume changes associated with recent glacials and interglacials. An interglacial period (or alternatively interglacial, interglaciation) is a geological interval of warmer global average temperature lasting thousands of years that separates consecutive glacial periods within an ice age.
Greenland ice cores show 24 interstadials during the 100,000 years of the Wisconsin glaciation. [3] Referred to as the Dansgaard–Oeschger event , they have been extensively studied, and in their northern European contexts are sometimes named after towns, such as the Brorup , the Odderade , the Oerel , the Glinde , the Hengelo, or the Denekamp .
Researchers say the planet seem naturally on track to escape an ice age for the next 50,000 years, an unusually long period of warmth.
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 ...
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.
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 over the past 3 billion years. The Late Cenozoic Ice Age began 34 million years ago, its latest phase being the Quaternary glaciation, in progress since 2.58 million years ago.
Reindeer evolved during the last ice age to withstand temperatures as low as minus 94°F (minus 70° C. ... and global warming have disrupted the reindeer’s natural migration patterns, making it ...
