This map of net radiation, incoming sunlight minus reflected light and outgoing heat, shows global energy imbalances. Areas around the equator absorbed about 200 watts per square meter more on average than they
reflected or radiated. Areas near the poles reflected and/or radiated about 200 more watts per square meter than
they absorbed. Mid-Latitudes were roughly in balance.

The net heating imbalance between the equator and poles is responsible for all BUT ONE of the occurrences posted here:

A) Ocean currents
B) Earth's climate
C) The four seasons
D) Air circulation patterns
