Global redistribution of heat by ocean currents. As global warming accelerates evaporative transfer of fresh water to poles, conveyor belt slows.
Winds move 60 % of “excess heat” from equator to poles (primarily via extratropical and tropical storms), while ocean currents move 40% (thermohaline “conveyor belt”).
