Melting ice, more rain drive Southern Ocean cooling

Global climate models predict that the ocean around Antarctica should be warming, but in reality, those waters have cooled over most of the past four decades .

Stanford University scientists have now found that the discrepancy between model results and observed cooling comes down to missing meltwater and underestimated rainfall.

As rising temperatures melt Antarctica 's ice sheet and cause more precipitation, the Southern Ocean's upper layer is growing less salty.

New method incorporates simulations from 17 different climate models.

Missing freshwater explains up to 60% of mismatch in observed and predicted Southern Ocean surface temperatures between 1990 and 2021 .

"We've known for some time that ice sheet melting will impact ocean circulation over the next century and beyond," Earle Wilson said.
