Volcanoes in the Andes may have cooled Earth by supercharging ocean life

AI BRIEFING

• ⬤ Volcanic eruptions in the Andes may have cooled Earth by releasing ash into the ocean, which helped to increase algae growth and reduce carbon dioxide levels, ultimately contributing to a global cooling event.
• ⬤ This phenomenon, which occurred millions of years ago, had a lasting impact on the planet's climate and ecosystems.
• ⬤ The discovery sheds new light on the complex relationships between volcanic activity, ocean chemistry, and the Earth's climate history.
