The lead oceanographer in this research says: “The deep oceans have been warming across much of the world for decades, so we were surprised to suddenly see this trend reversing and stabilizing in the Scotia Sea.”
Carbon dioxide up, warming down – surprising to some it seems.
The supply of dense Antarctic water from the bottom of the ocean to the Atlantic has declined in recent years, says Phys.org.
However, a new study explains for the first time how since 2014 this has stabilized and slightly recovered due to the variability in upstream dense waters, with implications for the global climate.
The study, led by British Antarctic Survey, is published this week in the journal Nature Climate Change.
