Reduced efficiency of the Barents Sea cooling machine

Nature Climate Change, Published online: 18 May 2020; doi:10.1038/s41558-020-0772-6 The Barents Sea cools the ocean, and dense water masses form that flow into the global overturning circulation. Hydrographic observations from 1971 to 2018 show reduced cooling efficiency with warmer Atlantic inflow, reduced sea ice and reduced wind-driven heat loss.
