Dim the Sun to 'Save Us' from Climate Change - 🤦 What Could Possibly Go Wrong?

Scientists want to spread dust in the upper atmosphere to see if it will stop climate change.

The idea is to dump calcium carbonate, basically chalk dust, into the stratosphere to block some of the sun's rays with the hope of halting the climate from warming.

It's called Stratospheric Aerosol Injection or SAI.
