The Ocean's Tipping Point

Gadget Lab: Weekly Tech News from WIRED - A podcast by WIRED - Thursdays

If you haven’t heard of it before, you’re about to become intimately familiar with the Atlantic Meridional Overturning Circulation. This system of currents—which brings water up the Atlantic from the southern tip of South America, through the tropics, and all the way to the coast of Iceland before looping back down south—plays a key role in keeping our planet’s climate stable. It keeps northern European winters relatively mild, it provides nutrients to ocean life, and it brings much-needed rain to agricultural systems in equatorial zones.Researchers who study the AMOC say this system is showing signs of instability, and it could shut down entirely—and soon. If the current slows down or stops, it would potentially kick off an ecological disaster of epic proportions. Deep cold spells, crushed food systems, entire regions in drought. This week, we bring WIRED features editor Sandra Upson onto the show to talk about the AMOC, the research that’s being done on it, and what life would be like on Earth if the current reaches its tipping point. Buckle up. Show Notes:Read “How Soon Will the Atlantic Ocean Break? Two Sibling Scientists Tried to Answer That—and Shook the World,” Sandra Upson’s WIRED feature on the researchers who are studying the AMOC and who have estimated the current could collapse in the next 30 years or so. Read our previous coverage of the AMOC research that kicked off the present debate about when it could reach the tipping point.Recommendations:Sandra recommends watching trashy reality shows in a language you’re trying to learn as an informal and entertaining study aid. Mike recommends embracing Brat Summer—IYKYK. Lauren recommends the book The Wave by Susan Casey, which is about the science and joy and terror of big waves.Sandra Upson can be found on social media @sandraupson. Lauren Goode is @LaurenGoode. Michael Calore is @snackfight. Bling the main hotline at @GadgetLab. The show is produced by Boone Ashworth (@booneashworth). Our theme music is by Solar Keys.
