Scientists discover massive icebergs once drifted off Britain's coast, offering insights into climate change.

Scientists have found evidence of massive icebergs, comparable in size to medium-sized UK cities, that drifted off Britain's coast about 18,000 years ago. Distinctive grooves in the North Sea floor, left by these icebergs, suggest they were five to tens of kilometers wide and 50-180 meters thick. These findings could offer insights into how climate change affects Antarctica and predict the impacts of current ice shelf disintegration.
