Scientists warn Gulf Stream could collapse as early as 2025

Scientists are warning that a crucial tipping point could be reached in 2025 - that would see the start of the collapse of the Atlantic Gulf Stream - if global emissions were not reduced.
The Atlantic Meridional Overturning Circulation, known as AMOC, drives the Atlantic's currents - by pushing warm water from the Gulf of Mexico northwards, towards the Arctic, where it cools and sinks.
It last collapsed during the previous ice age around 12,000 years ago - and could have catastrophic impacts for humanity.
Sea levels would rise around the East Coast of North America - and storms would worsen in Europe.
While rains in Asia, Africa and South America would be disrupted - causing issues for food production for billions of people.

Matthew England is an ocean and climate dynamics professor at the University of New South Wales. His Antarctic-focussed work is very similar to this latest study. He Joins us live from Sydney to discuss this.
