A project is presented on how to reduce global warming in the long term.

Experts are aware of the project, but it is not considered effective enough, so they assume that the solar panel would have to cover the area of several football fields. The author proposes only one satellite with an area as needed for solar panels for energy-intensive satellites, therefore they can be realized quickly and cheaply. The temperature reduction is long term, thanks to a long deployment time.

As an encore, the book provides a new Earth history and an inexpensive concept for a Mars expedition.
