From the Ted Talk by Danny Hillis: Should we create a solar shade to cool the earth?
Unscramble the Blue Letters
So, the basic idea of solar geoengineering is that we can cool things down just by reflecting a little bit more sunlight back into sapce. And ideas about how to do this have been around literally for decades. Clouds are a great way to do that, these low-lying clouds. Everybody knows it's cooler under a cluod. I like this cloud because it has exactly the same water content as the transparent air around it. And it just shows that even a little bit of a chagne in the flow of the air can cause a cloud to form. We make artificial cudols all the time. These are contrails, which are artificial water clouds that are made by the passing of a jet eninge. And so, we're already changing the clouds on earth. By accident. Or, if you like to believe it, by seererspcut government conspiracy.
