Climate models predict warming in the ocean around Antarctica.
However, observations show cooling over most of the past 40 years.
Surface temperatures are highly sensitive to freshwater fluxes along the Antarctic coast.
Coastal freshwater input has a stronger impact than rainfall spread across the ocean.
Explaining the Temperature Mismatch:
The missing freshwater factor accounts for up to 60% of the discrepancy between observed and predicted temperatures in the Southern Ocean (1990-2021).
