Climate change catastrophe took just months
Six months is all it took to flip Europe’s climate from warm and sunny into the last ice age, researchers have found.
They have discovered that the northern hemisphere was plunged into a big freeze 12,800 years ago by a sudden slowdown of the Gulf Stream that allowed ice to spread hundreds of miles southwards from the Arctic.
Previous research had suggested the change might have taken place over a longer period — perhaps about 10 years.
The new description, reminiscent of the Hollywood blockbuster The Day After Tomorrow, emerged from one of the most painstaking studies of past climate changes yet attempted.
