Science and Technology The warning hidden deep in Antarctica returns to the center of the climate crisis: scientists identify in the deep circulation of the Southern Ocean the mechanism that released CO₂ at the end of the last ice age and can now transform the ocean itself into an amplifier of global warming.

Science and Technology As if a giant sponge had failed at the planet’s southern extreme, the Southern Ocean is becoming saltier, losing ice at an alarming rate, and allowing deep heat to return to the surface, in a change capable of disrupting the circulation that regulates temperature, carbon, and storms across all Earth’s oceans.
