💡 Analysis & Explanation

Geoengineering Concepts Analysis ▼

Both 'cirrus cloud thinning' and 'stratospheric aerosol injection' are theoretical climate engineering (geoengineering) strategies.

Mechanism ▼

Injecting sulphate aerosols into the stratosphere mimics the cooling effect of massive volcanic eruptions by reflecting incoming solar radiation back into space. Cirrus cloud thinning aims to reduce the ice clouds that trap outgoing longwave terrestrial radiation. Both methods seek to cool the Earth's surface.

Conclusion ▼

These drastic measures are being studied specifically as potential emergency interventions to counteract and mitigate severe global warming.
