The onset of an ice age is related to the Milankovitch cycles where regular changes in the Earths tilt and orbit combine to affect which areas on Earth get more or less solar radiation. Another Ice Age in the future is a possibility. Waning through a succession of retreats and relatively minor advances it.

Currently we are in a warm interglacial that began about 11000 years ago. There have been four known Ice Ages on Earth in the 46 billion years that the planet has existed. If the ice age ended 11700 years ago then the 117 kiloyear marker should be close to the glacial maximum marker at the bottom of the graphics but this is not the case.

1 day agoThe age of the meteor impact crater discovered seven years ago underneath kilometer-deep ice in Greenland had long puzzled scientists. Woolly Mammoth lived during the last ice age 50000 years ago and the last ones died off around 3700 years ago. When did cavemen die. Roughly 20000 years ago the great.

At its thickest it was taller than the Empire State Building perhaps 2000 feet or more making it. The Ice Ages began 24 million years ago and lasted until 11500 years ago. It terminated abruptly in what are now the boroughs leaving the city with a unique landscape This resonated with me and reminded me of posts about Minnesotas Lake Agassiz as well as the Waterlines. The Huronian glaciation was the longest recorded ice age in earths history in which the planet witnessed global-scale glaciation approximately 2400 to 2100 million years ago.

At least five major ice ages have occurred throughout Earths history. The earliest was over 2 billion years ago and the most recent one began approximately 3 million years ago and continues today yes we live in an ice age.
