Earth cooled.

Answer 1

Reduced methane concentrations in the atmosphere typically lead to Earth cooling. Methane is a potent greenhouse gas, and lower concentrations result in less heat being trapped in the atmosphere, which can contribute to cooling effects. Therefore, the correct response is:

Earth cooled.
