As global efforts to reduce air pollution improve public health, they inadvertently accelerate climate change by removing cooling aerosols. This phenomenon, termed 'termination shocks,' reveals the complex interplay between air quality and climate stability, leading to extreme weather patterns and ecological risks. Researchers warn that while cleaner air is beneficial, it may also heighten global warming effects, necessitating careful consideration of future geoengineering strategies.

Why it matters

  • Air Quality Improvements: Efforts to reduce pollution have saved millions but also increased global warming.

  • Termination Shocks Explained: Rapid removal of aerosols can lead to extreme climate responses.

  • Impact on Weather Patterns: Changes in aerosol levels affect regional weather, including monsoons.

  • Geoengineering Risks: Future geoengineering interventions must consider complex climate interactions.
