Spreading particles in stratosphere to fight climate change may cost $2bn a year
Cooling the Earth by injecting sun-blocking particles into the stratosphere could be "remarkably inexpensive", according to the most detailed engineering analysis to date.
The fear of a rogue nation or military force unilaterally taking control of the global climate is unfounded, the researchers added, as the many thousands of high-altitude flights needed to affect global temperatures could not escape detection.
