The Southern Ocean has been dutifully gobbling up a century's worth of carbon dioxide 🌍 and heat 🔥 released by human activities, but when we finally let go of our fossil fuel habit, it might come back to haunt us. 👻

Southern Ocean Is Building a 'Burp' That Could Reignite Global Warming
The ocean's hidden payback.

Earth's mysterious 'hum' points to the sound of waves crashing across the world. Scientists first recorded Earth's low-frequency "hum" in the 1960s, but its origin was a mystery. It is now believed the hum is caused by ocean swells in the Southern Ocean, the sound of which echoes across the planet

The mysterious 'hum' of Earth and what scientists think is causing it
Earth is constantly humming with an ultra-low-frequency vibration that can be picked up right across the globe and has puzzled seismologists for decades. Growing evidence suggests it is the collective sound of the world's oceans constantly moving.
Climate simulations suggest the Southern Ocean could eventually shift from a major carbon sink to a net CO₂ source after emissions decline, as persistent ocean warming and changes in alkalinity weaken its capacity to absorb atmospheric carbon.

Enhanced carbon loss in the Southern Ocean under mitigation scenarios
The Southern Ocean (SO) plays a pivotal role in the global carbon cycle by absorbing anthropogenic carbon dioxide (CO2). Yet, it remains uncertain whether this role will persist under future mitigation efforts. Using idealized emission-driven simulations…
