Episode 349 One of the most vital systems of ocean currents - needed to keep life in northern Europe stable - is at risk of collapse. And now we can predict when it’s going to happen. Thanks to the work of climate scientists, we now have a model that tells us when major shifts in the Atlantic Meridional Overturning Circulation (AMOC) are expected. The AMOC is the Atlantic conveyor belt that keeps northern Europe temperate. If it turns off, northern Europe would be plunged into freezing conditions that would decimate agriculture and upend life as we know it. And it’s becoming clear that it is already weakening. Rowan Hooper is joined by climate journalist Alec Luhn. Together they explain how the AMOC and gulf stream work, why fears of a “tipping point” have been growing in recent years, and how this new model helps us prepare for the worst. Also hear from climate scientist René van Westen, who co-authored the report in Nature.

  • This week we have news about a much feared tipping point concerning the Atlantic Meridional Overturning Circulation,

  • AMOC.

  • That's the Atlantic conveyor belt that transports warm water from the tropics northward and that helps keep Northern Europe temperate.

  • It's what we've relied on for thousands of years.

  • If this conveyor belt turns off, Northern Europe would be plunged into freezing conditions.

  • It would basically destroy agriculture across most of the continent.

  • It's very bad news.

  • So it's vital that we understand the behaviour of the AMOC and have an early warning of

  • if it's going to collapse so that we can...

  • perhaps do something about it.

  • That's what we're getting into on this episode of The World,
