It sounds like a wacky idea out of science fiction - but it’s backed in part by billionaire Microsoft founder Bill Gates and top scientists from Harvard.
The researchers believe that a fleet of specially designed aircraft could spray sulfate particles into the lower stratosphere to cool down our planet and offset the effects of climate change.
A test of the technology has been proposed for this year, the Daily Mail reports, with the Stratospheric Controlled Perturbation Experiment (SCoPEx) seeing a bag of carbonate dust released into the atmosphere 12 miles up.
If that experiment proves successful, the researchers will move on to releasing the dust from planes.
This week, advocates from all walks of life are engaging in a campaign to #MeetBillGates and his stranglehold on our lives. Our freedom. Our medical care. Imagine a human being able to control the sun? Let's call the project "ICARUS."
