Researchers propose using cargo planes to spray particles above poles to cool Earth, but warn it's not a replacement for emissions cuts.
A new UCL study suggests that existing cargo planes, like the Boeing 777F, could be used to cool the Earth by spraying particles above the polar regions, a process called stratospheric aerosol injection.
The technique involves releasing sulfur dioxide particles to reflect sunlight, potentially cooling the planet by 0.6°C annually.
However, the method could cause issues like acid rain, and the study emphasizes that it is not a replacement for reducing greenhouse gas emissions.
