Should we create a solar shade to cool the earth?

Reflecting sunlight into space using chalk dust could cool Earth to pre-industrial levels, showcasing human ingenuity in climate solutions.

Exploring solar geoengineering, using stratospheric chalk to reflect sunlight may cool Earth with minimal environmental impact.

Critics fear solar geoengineering could deter focus from reducing fossil fuel reliance, despite its potential to mitigate climate change.
