This image of the circulation of the oceans for the entire planet is fascinating and beautiful.
The current shape of the oceans has created the Gulf Stream which is the primary determinant of the Northern Hemisphere climate. It was fisherman from Portugal who sailed the Gulf Stream that carried the information about ocean currents that connected Europe to America via C. Columbus. It was changes in the Gulf Stream that allowed Vikings to settle in Canada, Greenland and Iceland as well as to populate and dominate Russia, England and France.
The other important notable fact from this illustration shows the way that the Pacific El Nino, La Nina pattern has an influence on the Atlantic and the climate of the whole world.
I personally use the data that discovered this global ocean flow in the past few decades to recognize that global warming is trivial and has nothing to do with human carbon generation.
