In a matter of decades, melting glaciers could shut down the Gulf Stream - the system of currents that brings warmth to the Northern Hemisphere, experts say. Without this additional warmth, average temperatures could drop by several degrees in North America, parts of Asia, and Europe. The scientists warn that an abrupt shutdown of Atlantic Ocean currents is looking more likely than ever, as computer simulations find a 'cliff-like' tipping point looming in the near future.
'We are moving closer to the collapse, but we're not sure how much closer,' said lead author Rene van Westen, a climate scientist and oceanographer at Utrecht University.
The Gulf Stream is part of a much wider system of currents, officially called the Atlantic Meridional Overturning Circulation or AMOC. Described as 'the conveyor belt of the ocean', it transports warm water near the ocean's surface northwards - from the tropics up to the Northern Hemisphere. Scientists say that the Gulf Stream shutdown could have severe and cascading consequences around the world.
When a global weather calamity like the one in 'The Day After Tomorrow' may happen is 'the million-dollar question', according to van Westen.
