Volcano Cleans Its Own Methane Pollution
30 May
Summary
- Volcanic eruption created formaldehyde, indicating methane breakdown.
- Salty water vapor and ash from volcano aided methane destruction.
- Findings may inform new methods to tackle methane pollution.
In January 2022, a violent underwater volcanic eruption in the South Pacific generated a formaldehyde cloud, revealing a surprising self-cleaning mechanism for methane.
The Hunga Tonga-Hunga Ha'apai volcano's powerful eruption propelled salty water vapor and ash into the stratosphere, creating conditions that scientists believe helped break down methane. This process, indicated by the formaldehyde cloud observed for over a week, suggests the volcano neutralized some of its own pollution.
Researchers estimate the eruption released approximately 330,000 tons of methane, with around 900 tons being broken down daily. This finding offers potential new avenues for tackling methane, a significant contributor to global warming.
Experts suggest these insights could inform geoengineering strategies to reduce atmospheric methane. However, they also urge caution, emphasizing the need for extensive research to understand potential unintended consequences and ensure safety and effectiveness.
