Earth cooled.

Answer 1

Reduced methane concentrations in the atmosphere would likely lead to Earth cooling. Methane is a potent greenhouse gas, and its reduction would result in less heat being trapped in the atmosphere, thereby contributing to a cooling effect. Therefore, the correct response is:

Earth cooled.
