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.
An artist's impression of the last glacial period at glacial maximum [4]. The LGP is often colloquially referred to as the "last ice age", though the term ice age is not strictly defined, and on a longer geological perspective, the last few million years could be termed a single ice age given the continual presence of ice sheets near both poles.
1650, not the start of the Little Ice Age, but the start of the coldest years midway through, i.e., the First Climatic Minimum [clarification needed] The Little Ice Age ended in the latter half of the 19th century or in the early 20th century. [21] [22] [23] The 6th report of the IPCC describes the coldest period in the last millennium as: [24]

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
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. The Last Glacial Period ended about 15,000 years ago. [1]
Scientists warn that the Earth is just 15 years away from experiencing a "mini ice age" — something that hasn't happened in 300 years. Researchers in the U.K. created a new model of the Sun ...
Throughout Earth's climate history (Paleoclimate) its climate has fluctuated between two primary states: greenhouse and icehouse Earth. [1] Both climate states last for millions of years and should not be confused with the much smaller glacial and interglacial periods, which occur as alternating phases within an icehouse period (known as an ice age) and tend to last less than one million years ...
