Atmosphere, Not Oceans, Carries Most Heat to Poles
National Center for Atmospheric Research (NCAR)

According to a new study from the National Center for Atmospheric Science, the atmosphere redistributes annually as much heat from the tropics to the poles as would be produced by five million of the world's biggest power stations, generating 1,000 megawatts each. This is far more than the oceans carry poleward.
