The debate has raged for decades: Was it humans or climate change that led to the extinction of many species of large mammals, birds, and reptiles that have disappeared from Earth over the past 50,000 years?

During ice ages, dry, frozen terrain extended over much of northern Europe, Asia and North America. Many plants and animals retreated from these desolate, harsh landscapes and sought refuge in pockets of more hospitable territory.

Glacial cyclicity of the Earth has often been considered on 100,000 year timescales, particularly for the Late Pleistocene (~11,700 to 129,000 years ago) swapping between periods of extensive polar and mountain glacier ice ...
Earth has experienced significant changes in its climate over the past ~2.6 million years (the Quaternary) with a series of glacial and interglacial cycles that have transformed our landscapes. This involves erosive action ...
Approximately 700,000 years ago, a "warm ice age" permanently changed the climate cycles on Earth. Contemporaneous with this exceptionally warm and moist period, the polar glaciers greatly expanded. A European research team ...

A glacial period is an interval of time within an ice age that is marked by colder temperatures and glacier advances. Interglacials, on the other hand, are periods of warmer climate within an ice age. The last glacial period ended about 10,000 to 15,000 years ago; the current Holocene epoch is the interglacial we are presently in.
