Climate journalists Alec Luhn, who reports on environmental crises and their political fallout, and Madeleine Cuff, a specialist in climate policy and Earth-system tipping points, explore the Atlantic’s fragile conveyor belt. They examine how scientists could warn of collapse, possible climate and food-system upheaval, and whether a stalled AMOC might someday be revived. Greenland melt, interacting tipping points and the race to cut emissions also come under scrutiny.

Episode notes
The AMOC Makes Europe Surprisingly Mild
- The AMOC transports 1.2 petawatts of heat, profoundly moderating Europe’s climate.
- Bergen averages 2.6°C in January, while similarly located Anchorage averages −8.4°C, illustrating the current’s influence.
Greenland Melt Could Slow The Ocean Conveyor
- Evidence suggests the AMOC has weakened roughly 15%, though direct measurements span only about 20 years.
- Greenland’s freshwater dilutes salty water, reducing its density and slowing the sinking that drives circulation.
A Past AMOC Collapse Offers A Warning
- The Younger Dryas saw Earth return to ice-age conditions for about 1,300 years as freshwater likely disrupted the AMOC.
- Greenland now releases icebergs and meltwater five times faster than 30 years ago.
