Southern Ocean Salinity and Ice Loss Threaten Global Carbon Circulation

A recent study from the University of Southampton reveals that the Southern Ocean is becoming saltier and losing ice faster than climate models predicted. These changes are allowing deep heat to rise to the surface, potentially disrupting the global ocean currents that regulate Earth's temperature and carbon storage. Researchers used European satellite data from 2015 to 2024 to document this shift. The findings suggest a fundamental change in the ocean's state, which could have long-term impacts on storm patterns and the planet's ability to sequester carbon.
