Earth Talk :Sprinkling dust to Protect the Earth?

Some certainly do consider it science
What we’re talking about is a form of geoengineering that entails sending up some 800 jumbo planes to sprinkle their payload of millions of tons of chalk dust in the stratosphere 12 miles above the Earth’s surface in an effort to reflect some of the sun’s heat back into space to turn the tide on climate change.
The so-called Stratospheric Controlled Perturbation Experiment (SCoPEx) was developed by chemist James Anderson and physicist David Keith, both of Harvard— with funding from Bill Gates—“to advance understanding of stratospheric aerosols that could be relevant to solar geoengineering.” The researchers want to test their hypothesis with a $3 million experiment 12 miles above the Southwestern United States where they would steer remote controlled balloons to disperse small plumes of calcium carbonate.
