Earth's last Glacial Maximum period began around 33,000 years ago, when vast ice sheets covered much of the Northern Hemisphere.
At the time, the Eurasian ice sheet -- which covered much of Scandinavia -- contained approximately three times the amount of frozen water held in the modern-day Greenland ice sheet.
But rapid regional warming saw the ice sheet collapse over a period of just 500 years, according to authors of the study published in Nature Geoscience.
Analysing sediment drill cores from the Norwegian Sea, the team found that the ice sheet's collapse contributed to an event known as Meltwater 1A -- a period that saw as much as 25 metres added to global sea levels between 13,500-14,700 years ago.
Lead author Jo Brendryen from Norway's University of Bergen said the Eurasian ice sheet melt coincided with vast regional temperature swings.
The study showed that the entire Eurasian ice sheet melted in a matter of a few centuries, adding more than four centimetres to sea levels annually -- around 4.5-7.9 metres in total.

Hail Atlantis!
Earth's LAST Glacial Maximum???
You mean there's been more than one? What happened in between?
Whoa. What caused that?
Go back to that glacier period around 13,000 years ago, over the entire NE of the US. That one-mile thick glacier melted in a matter of weeks, and raised sea levels by 200 to 300 ft (where they are today).
These cycles come and go. But the speed part is the unknown.
“33,000 years ago”
I owned beachfront property back then.

Bush’s fault.
Pretty close to Noah?
Low taxes.
Vikings driving Humvees.
Neanderthals driving to their summer homes, probably. Because they were Neanderthals, they didn’t invent a carbon tax. So they lost their lovely continental glaciers and the good times hunting mammoths. If only they had listened to Al Cavegore.
Say, isn’t that around the time that humans discovered fire?
Back then, Noah probably got blamed for global warming. Now, Trump is. Noah is probably glad to be off the hook. 😁🤪😆
40 miles inland and 600 feet above sea level. Not worried.
So what?

” What happened in between? “
We happened in between. All of civilization has happened in an odd portion of temperate weather. For the most part, Earth has been covered with ice. Wait until the current ice age, which we are still technically in, resumes. Then all of us will be required to burn a barrel of oil per day.
