Will a Warmer climate stop the Gulf Stream part III

One thing that complicates the whole argument about the melting of ice sheets and lower salinities in the North Atlantic is something so unexpected as winds. There is is a constant westerly wind blowing, a so-called TRADE WIND , at the same latitude as the Panama Canal. In that part of the Atlantic much fresh water naturally evaporates because of the heat. The Tradewind then transports this water westward to the Pacific Ocean. This increases the salinity of the Atlantic and decreases it instead in  the Pacific !

 

The trade winds help to keep up the salinity of the Atlantic. The question is whether the increased supply of fresh water in the North Atlantic, by melting ice, may over- compensate for the wind borne removal to the Pacific Ocean so that the salinity of the North Atlantic is still dropping and mixing operations cease (read previous posts).

The data reported by the UN climate commission shows that the surface layer in the Pacific have become fresher in recent years while the surface of the Atlantic Ocean has become more saline . The calculations show that salinity reduction in the Pacific represents a loss of freshwater from the Atlantic which are significantly larger than the contributions by the melting of the Greenland ice sheet . What do they really mean? The salinity may well be increasing instead of decreasing in the Atlantic!
