Ancient Supervolcano Eruption Had Minimal Effect on Climate

Speedy Summary

• Recent geochemical evidence from India challenges the belief that the Toba supervolcano eruption 74,000 years ago caused a severe volcanic winter.
• Analysis of ancient sediments suggests that the eruption rather led to several years of warm and dry weather.
• The Toba supervolcano eruption was colossal, releasing thousands of cubic kilometers of volcanic material into the atmosphere.
• Volcanic eruptions are generally known to influence climate due to sulfur dioxide emissions, which can block sunlight and led to cooling episodes.
