If methane in the atmosphere decreases, energy in the Earth system would . . .

Accepted Answer

Decrease, because less energy would enter than exit.

Answer

Decrease, because more energy would enter than exit.

Question 13

Ice core data from Greenland indicates there was a time period on Earth when the atmosphere changed so more energy entered the Earth system than exited.

What change to the atmosphere could have caused this?

Accepted Answer

Carbon dioxide increased, leading to more energy in the Earth system because more exiting energy bounced back toward Earth.

Answer

Carbon dioxide decreased, leading to more energy in the Earth system because less energy from the sun bounced back toward outer space.
