The actual reason that the equator is so much warmer than the poles is because the solar radiation strikes the Earth nearly straight on, while at the poles it strikes the Earth at an angle, writes ...

BOULDER — According to a new data analysis, 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 ...

In general, air heats near the equator, rises, then moves toward the poles. This air then cools and sinks to move back toward the equator.

In their simulations, the high-latitude oscillations carry heat from the solar poles to the equator, which limits the temperature difference between the Sun’s poles and the equator to less than ...

A geomagnetic event around 41,000 years ago sent the aurora wandering for centuries, as far south as the equator.
