The British-Irish Ice Sheet (BIIS), [2] also known as the Irish Sea Glacier was an ice sheet during the Pleistocene Ice Age that, probably on more than one occasion, flowed southwards from its source areas in Scotland and Ireland and across the Isle of Man, Anglesey and Pembrokeshire. [3]

During deglaciation since the Last Glacial Maximum, between about 20,000 to 7,000 years ago (20–7 ka), the sea level rose by a total of about 100 m (328 ft), at times at extremely high rates, due to the rapid melting of the British-Irish Sea, Fennoscandian, Laurentide, Barents-Kara, Patagonian, Innuitian and parts of the Antarctic ice sheets ...
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.

The ice core record showed a cold oscillation between 14,025 to13,904 years BP, which is reflected in the increased δ 18 O during this period. This cold oscillation was also observed in earlier ice core records (GRIP [ 10 ] [ 11 ] and GISP2 [ 12 ] [ 13 ] [ 14 ] ) drilled in the early 1990s by GRIP members.
During deglaciation between about 19– 8 ka, sea level rose at extremely high rates as the result of the rapid melting of the British-Irish Sea, Fennoscandian, Laurentide, Barents-Kara, Patagonian, Innuitian ice sheets and parts of the Antarctic ice sheet. At the onset of deglaciation about 19,000 years ago, a brief, at most 500-year long ...
The last Ice Age was followed by the Late Glacial Interstadial, a period of global warming to 12.9 ka, and the Younger Dryas, a return to glacial conditions until 11.7 ka. Paleoclimatology holds that there was a sequence of stadials and interstadials from about 16 ka until the end of the Pleistocene.
