The results are published in the journal Nature Climate Change. A team at British Antarctic Survey (BAS) examined the potential impact of computer-produced warming scenarios on over 960 species of seafloor marine invertebrates with known habitats south of 40°S. Southern Ocean seafloor water temperatures are projected to warm by an average of 0.4°C over this century with some areas possibly increasing by as much as 2°C.…
