You're welcome.

Answer:

Earth cooled.

Explanation:

The reduced methane concentrations in the atmosphere affect Earth :

  • Particles of gas and dust released into the atmosphere during a volcanic eruption affect the climate.
  • Most of the particles emitted by the  volcano cool the planet by blocking incoming solar radiation.
  • The cooling effect can last from months to years, depending on the nature of the eruption.

Therefore, the Earth is cooled.
