In the original version of this Article, the following content has been added: “The simulated Antarctic sea ice expansion in CESM1-ASI also brings on a conspicuous increasing trend of surface salinity from the Antarctic coast to 60oS and a surface freshening trend north of 60oS in the Southern Ocean (Figure 1I), as consistent with the pattern of observed SSS change3 (Figure 1H). The underlying rationale is that sea ice forms around the Antarctic coast, moves northward due to meridional wind drift, and melts in the open ocean in lower latitudes. Between 1979 and 2013, CESM1-ASI witnesses a large trend of equatorward sea-ice freshwater transport in the”
