Climate Mitigation Poster

Space mirrors placed in orbit around Earth could reflect sunlight away and cool the planet by up to 3°C. The mirrors would be made of thin reflective plastic foil and have a size of one square kilometer. While producing and deploying many mirrors would be challenging, the initial investment of $1 billion could place around 100 mirrors in space.
