The plans sound like something out of the handbook of a James Bond villain: generate artificial volcanic eruptions, seed colossal clouds that shade the planet, cover the oceans in immense algal blooms visible from space.

In The Planet Remade, journalist Oliver Morton presents the need for a real-life “Greenfinger” to cool the planet. Curbing humankind’s fossil fuel habit within the next few decades is just too tall an order considering today’s lackluster energy alternatives, he argues.
