Conclusions:           if the earth is considered to be a uniform ball all of one substance then:

 

(1)     On average, the earth's suface and the atmosphere are warmer at the Equator than at the Poles;

 

(2)     On average, there is a tremendous fluctuation from winter to summer temperatures in the polar regions and none at all in the equatorial regions.  No seasons at the equator.
