What would happen to energy in the Earth system if methane in the atmosphere decreases?

Back

decrease, because less energy would enter than exit. This is because less exiting energy would be redirected (bounced) back toward Earth.

How should the energy in the Earth system change when the amount of methane in the atmosphere increases?

Back

more energy in the Earth system and more energy absorbed by Earth’s surface, because more energy enters than exits.

Good evidence shows trends over a long period of time instead of fluctuations within a short period of time.

What happened to energy in the Earth system when a large amount of carbon dioxide was released from rock on the ocean floor 120 to 80 million years ago?

Back

increased, because more energy entered than exited. This is because more exiting energy was redirected (bounced) back toward Earth.
