Your article basically points out two facts with regard to sea ice, both the decrease in the Arctic, and the increase in the Antarctic, both caused by global warming.

The article also points out that the climate models cannot reproduce the likely historical trends in sea ice which means the models' ability to predict future trends is zero. Hand waving about sea salinity does make the problems with the models go away.

Science is useful when it tells us what we don't know but the problem with climate science is the "approved narrative" does not allow scientists to acknowledge that the models are poor approximations of the real world and should never be treated as "predictions".  Statements like 2degC as the limit to prevent "dangerous" warming are unscientific nonsense.
