Cargo Planes Could Cool Overheating Planet
72% Informative
Scientists at University College London say existing aircraft could be used to cool Earth by spraying particles high above the polar regions.
The technique, known as stratospheric aerosol injection, works by releasing sulfur dioxide particles into the upper atmosphere, where they reflect incoming sunlight before it can warm the planet.
The discovery potentially moves geoengineering from theoretical concept to something that could be implemented more quickly.
