Article: Current knowledge about ocean circulations (AMOC and others) and their variability are so unsettled that the most sophisticated and powerful climate models are completely unable to accurately forecast these gargantuan climate forces.
Ocean circulation is responsible for the immense global heat transport that affects every facet of world climate. And yet, the scientists remain perplexed as to the mechanics and intricacies of the entire system.
But what do the climate scientists know for sure? Well...that human CO2 emissions have absolutely nothing to do with this natural ocean circulation heat transport and weather system. That part is settled.
