Southern Ocean: Small-Scale Processes Reshape Global Climate Outcomes

The Southern Ocean profoundly influences global climate by absorbing significant CO2 and heat. Recent research reveals small-scale processes like freshwater-driven stratification are enhancing its carbon sink, unexpectedly altering global climate outcomes, though this effect may be temporary.

• Southern Ocean crucial for global climate, absorbs CO2 and heat.
• Small-scale oceanic processes unexpectedly reshape climate outcomes.
• Freshwater-driven stratification traps deep, carbon-rich waters.
• Anomaly shows Southern Ocean strengthening as a carbon sink.
• Future carbon release possible if stratification weakens.
• Improved climate models needed for accurate projections.
