@dave sss; that's one Hell of a lot of additional energy that human activity has pumped into our oceans - nor can energy be 'destroyed'.
Warmer oceans means higher evaporation rats, stronger air pressure cells, greater precipitation and huge impacts on life-forms adapted for cooler conditions.
Those living on coasts already under attack from erosion as well as those living on riverine flood plains and low elevation islands are first cabs of the rank for increased risks.
