In this episode of The Climate Translation, Dr. Mac explores the growing concern among scientists that several major Earth systems may be more tightly connected than we once understood. Beginning with melting in Greenland, he explains how freshwater entering the North Atlantic can influence ocean circulation, alter tropical rainfall patterns that affect the Amazon rainforest, and contribute to changes in heat distribution that reach all the way to Antarctica’s vulnerable ice shelves.

We break down what scientists actually mean when they talk about “tipping points.” Rather than sudden collapse, these thresholds describe shifts in stability, where gradual change  ...
