Rotating globe showing sea-surface temperature with a cycling colour-coding, illustrating the transport of heat from the Equator to the poles. The ocean and atmosphere act to reduce temperature differences by transporting heat from the Equator to the poles. Without these heat engines, equatorial regions would be 10degC warmer, and the poles would be 20degC cooler than they are today. At low latitudes it is estimated that up to 74% of poleward heat transport is due to ocean currents.
