The risks of global warming are pressing and potentially vast.

The difficulty of doing without fossil fuels is daunting, possibly even insurmountable. To meet that need, a small but increasingly influential group of scientists is exploring proposals for planned human intervention in the climate system: a stratospheric veil against the sun, the cultivation of photosynthetic plankton, fleets of unmanned ships seeding the clouds.

These are the technologies of geoengineering—and as Oliver Morton argues in this visionary book, it would be as irresponsible to ignore them as it would be foolish to see them as a simple solution to the problem.
