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 2-5oC 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 b deployed and processed using existing technology, similar to methods proposed for space habitat construction. The cost may be substantially lower than the economic and human damage caused by a significant climate change.
