LAD BIBLE - Scientists have warned that the Gulf Stream could collapse altogether, having weakened significantly over the past 100 years.
Without it, you've got the possibility of rising sea levels, climate change, and unliveable temperatures.
What is the Gulf Stream?
The Gulf Stream is often described as the world's 'conveyor belt' as it transports warm, salty water to the north and releases heat to western Europe, across the Atlantic, and circulates back south.
It's part of a much wider system of currents, referred to as the Atlantic Meridional Overturning Circulation (AMOC).
If the Gulf Stream collapses, however, you've potentially got all sorts of problems.
Why is the Gulf Stream collapsing?
Researchers from the University of California, Riverside, have concluded that the AMOC 'has been weakening for more than a century'.
Because greenhouse gases continue to rise, 'that trend is likely to continue', according to Professor Wei Liu, an author of the study.
