A Space-Based Solar Screen Against Climatic Warming, Michael Noah Mautner

Chemistry Publications

The expected global warming may be reversed by space-based screen that would intercept a fraction of the solar radiation incident on Earth. Warming by 2-5^oC could be prevented by intercepting 3-7%, respectively, of the incident solar radiation. The screen may be constructed for example of a thin film, a grid of film supported by a mesh or fine-grained dust deployed in orbit about the Earth. For an average film thickness or particle radius of 0.001 cm, the required mass is 10¹⁴ - 10¹⁵ g, equivalent to a medium sized lunar mountain or asteroid. The material may …
