[[File:Phanerozoic Climate Change.png|thumb|350px|Climate history over the past 500 million years, with the last three major ice ages indicated,
[[Andean-Saharan glaciation|Andean-Saharan]] (450 Ma), [[Karoo Ice Age|Karoo]] (300 Ma) and [[Late Cenozoic Ice Age|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 age]]s 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.

Within ice ages, there exist periods of more severe glacial conditions and more temperate conditions, referred to as [[glacial period]]s and [[interglacial|interglacial period]]s, respectively.  The Earth is currently in such an interglacial period of the Quaternary glaciation, with the [[Last Glacial Period]] of the Quaternary having ended approximately 11,700 years ago.  The current interglacial is known as the [[Holocene]] epoch.<ref name="Walker, M. 2009. pp. 3">Walker, M., Johnsen, S., Rasmussen, S.

A minor series of [[wiktionary:glaciation|glaciations]] occurred from 460 to 430&nbsp;Ma, and there were extensive glaciations from 350 to 289&nbsp;Ma.

The [[Late Cenozoic Ice Age]] has seen extensive ice sheets in [[Antarctica]] for the last 34&nbsp;Ma. During the last 3&nbsp;Ma, ice sheets have also developed on the northern hemisphere. That phase is known as the [[Quaternary glaciation]], and was marked by more or less extensive glaciation. They first appeared with a dominant frequency of 41,000 years, but after the [[Mid-Pleistocene Transition]] that changed to high-amplitude cycles, with an average period of [[100,000-year problem|100,000 years]].<ref name="Willeit">{{cite journal|title=Mid-Pleistocene transition in glacial cycles explained by declining CO2 and regolith removal &#124; Science Advances|journal=Science Advances|date=April 2019 |volume=5 |issue=4 |pages=eaav7337 |doi=10.1126/sciadv.aav7337 |last1=Brovkin| first1=V.| last2=Calov| first2=R.|last3=Ganopolski| first3=A. |last4=Willeit |first4=M. |pmid=30949580 |pmc=6447376}}</ref>

== Nomenclature of Quaternary glacial cycles ==
Whereas the first 30 million years of the Late Cenozoic Ice Age mostly involved Antarctica, the [[Quaternary glaciation|Quaternary]] has seen numerous ice sheets extending over parts of Europe and North America that are currently populated and easily accessible. Early geologists therefore named apparent sequences of glacial and interglacial periods of the Quaternary Ice Age after characteristic geological features, and these names varied from region to region. The marine record preserves all the past glaciations; the land-based evidence is less complete because successive glaciations may wipe out evidence of their predecessors. [[Ice cores]] from continental ice accumulations also provide a complete record, but do not go as far back in time as marine data. [[Pollen]] data from lakes and bogs as well as [[loess]] profiles provided important land-based correlation data.<ref name="Davis">{{cite web |author=Davis, Owen K. |title=Non-Marine Records: Correlations with the Marine Sequence |work=Introduction to Quaternary Ecology |publisher=University of Arizona |url=http://www.geo.arizona.edu/palynology/geos462/07nonmarin.html |url-status=dead |archive-url=https://web.archive.org/web/20170727164508/http://www.geo.arizona.edu/palynology/geos462/07nonmarin.html |archive-date=2017-07-27 }}</ref> The ''names'' system has mostly been phased out by professionals. It is now more common for researchers to refer to the periods by their [[marine isotopic stage]] number.<ref name="Gibbard">{{cite book |author1=Gibbard, P. |author2=van Kolfschoten, T. |chapter=Chapter 22: The Pleistocene and Holocene Epochs |chapter-url=http://www-qpg.geog.cam.ac.uk/people/gibbard/GTS2004Quat.pdf |editor1=Gradstein, F.

Gilbert |title=A Geologic Time Scale 2004 |publisher=Cambridge University Press |location=Cambridge |year=2004 |isbn=978-0-521-78142-8 }}</ref>  For example, there are five Pleistocene glacial/interglacial cycles recorded in marine sediments during the last half million years, but only three classic glacials were originally recognized on land during that period ([[Kansan glaciation|Mindel]], [[Wolstonian Stage|Riss]] and [[Wisconsin glaciation|Würm]]).<ref>{{cite journal |author=Kukla, George |title=Saalian supercycle, Mindel/Riss interglacial and Milankovitch's dating |journal=Quaternary Science Reviews |volume=24 |issue=14–15 |pages=1573–83 |date=August 2005 |doi=10.1016/j.quascirev.2004.08.023 |bibcode=2005QSRv...24.1573K }}</ref>

Land-based evidence works acceptably well back as far as MIS 6 (see [[Marine isotope stages]], Stages), but it has been difficult to coordinate stages using just land-based evidence before that. Hence, the "names" system is incomplete and the land-based identifications of ice ages previous to that are somewhat conjectural.  Nonetheless, land based data is essentially useful in discussing landforms, and correlating the known marine isotopic stage with them.<ref name="Davis"/>

=== Uncertain correlations ===
It has proved difficult to correlate the traditional regional names with the global marine and ice core sequences. The indexes of [[Marine isotope stage|MIS]] often identify several distinct glaciations that overlap in time with a single traditional regional glaciation. Some modern authors use the traditional regional glacial names to identify such a sequence of glaciations, whereas others replace the word "glaciation" with "complex" to refer to a continuous period of time that also includes warmer stages. As shown in the table below, it is only during the last 200-300 thousand years that the time resolution of the traditional nomenclature allow for clear correspondence with MIS indexes. In particular there has been a lot of controversy regarding the glaciations MIS 10 and MIS 12, and their correspondence to the [[Elster glaciation|Elster]] and [[Mindel glaciation]]s of Europe.<ref>{{cite journal|author=Böse|display-authors=etal|year=2012|title=Quaternary Glaciations of Northern Europe|journal=Quaternary Science Reviews|issue=44|page=17|citeseerx=10.1.1.734.1691 }}</ref>
