Stratospheric aerosol injection would work by releasing tiny particles into the atmosphere’s dry, stable upper layer called the stratosphere. These particles would scatter sunlight back into ...

Spending decades grinding up something approaching a quadrillion dollars worth of diamonds into dust ... particles in the atmosphere — is known as stratospheric aerosol injection.

Blocking the sun by injecting tiny particles in the atmosphere – called solar geoengineering – can lower the Earth’s temperature but has some real costs. Economists run the numbers.
