Scientists document a loss equivalent to detonating a Hiroshima nuclear bomb

Ocean currents, propelled by kinetic energy from the wind, are the great moderators of the Earth's climate. By transferring heat from the equator to polar regions, they help make our planet habitable.

And yet, the large-scale models used by scientists to study this complex system fail to accurately account for the impact of wind on the ocean's most energetic components: swirling, mesoscale eddies. These circular currents of water 50 to 500 kilometers in size are critical to determining the trajectory of larger ocean currents like the Gulf Stream.

And even more, a situation, in which most of the other people we are speaking to, don't know it too, though they, more or less, understand what we mean.
