The formation of sea ice causes the concentration of salt in surface waters to increase; less sea ice would mean a smaller increase in the concentration of salt.
海冰的形成导致表水中盐的浓度增加；海冰的减少意味着盐浓度的增加幅度较小。

If you replenish the ice sheets and frozen waters of the high latitudes, more light will be reflected back into space, so reducing the warming of the oceans and atmosphere.
如果高纬度地区的冰原和冻结的水得到补充，更多的光将被反射回太空，从而减缓海洋和大气的变暖。

Thus, although the winter sea-ice cover might decrease, the surface waters would remain cold enough so that the decrease would not be excessive.
