Question:

Mars has a more eccentric orbit of the Sun than Earth. Mars is 20% closer to the Sun during its winter than it is during its summer. How would temperature distributions on Earth be affected if we had a similarly eccentric orbit that brought us much closer to the Sun during winter in the Northern Hemisphere?

a. Maximum temperatures would be higher during the winter season in the Northern Hemisphere.
b. Maximum temperatures would be higher during the winter season in the Southern Hemisphere.
c. Maximum temperatures would be higher during the winter seasons in both the Northern and Southern Hemispheres.
