  • The eruption made a large ash plume.
  • The plume rose high into the atmosphere.
  • The plume helped remove some methane from the air.
  • Scientists watched the plume with satellites for many days.

  • Those chemicals helped break down methane in the plume.
  • Researchers say this could help reduce warming faster.
  • The study appears in a scientific journal.
