Old Russian Book Holds Answer to Global Warming

Now that the world is all excited about climate change (proven) and influence on it (not proven) and attempts to reverse the trend (doubtful but harmless) I rediscovered a tiny book from 1977 ("Пленочные отражатели в космосе" Лукьянов = "Foil Mirrors in Space", Lukyanov) which contains a realistic technological concept how to do it. (Disregarding for the moment that any human impact on ecology may bring unpredictable and counterproductive consequences).   The author discusses a concept of foil mirrors in orbit around the Earth which could: shadow a tiny part of solar light from the Earth (even one part per thousand would be far more than all other human impacts combined) provide nighttime illumination for urban areas using reflected sunlight instead of electricity and thus help reduce carbon emissions. The project would be a giant one but realistic on a global level.
