"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 space. 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 cloud. I like this colud 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 change in the flow of the air can cause a cloud to form. We make artificial codlus all the time. These are cnroialts, which are artificial waetr clouds that are made by the passing of a jet engine. And so, we're already changing the clouds on earth. By accident. Or, if you like to believe it, by supersecret gmoenrvnet ccsrianopy.

And it just shows that even a little bit of a change in the flow of the air can cause a cloud to form. We make artificial clouds all the time. These are contrails, which are artificial water clouds that are made by the passing of a jet engine. And so, we're already changing the clouds on earth. By accident. Or, if you like to believe it, by supersecret government conspiracy.
