Story summary

Stanford University researchers have uncovered a surprising trend: the Southern Ocean has cooled over the last 40 years, defying climate models that forecast warming. This cooling is attributed to rising meltwater and precipitation, which dilute salinity and hinder warm water mixing. Their groundbreaking findings highlight the crucial role of freshwater inputs in shaping climate models and global climate forecasts.
