Oxford University’s Geoegineering Programme defines the process as “the deliberate large-scale intervention in the Earth’s natural systems to counteract climate change” and a new book, Geoengineering: The Gamble discusses its potential benefits and pitfalls. The author, Gernot Wagner, is a climate economist who teaches at New York University and was the founding executive director of Harvard’s Solar Geoengineering Research Program. The opening sentence of the book is: “The first time I heard about solar geoengineering, I considered the idea nuts.” It's a useful admission, because directly intervening in the world's climate provokes much the same reaction from most people.

Wagner sums up the case for geoengineering as “fast, cheap and imperfect.” It's fast, because it could lower global temperatures far more quickly than cutting emissions. It's not really cheap, potentially costing many billions of dollars, but that's still a lot less than the trillions that we're spending attempting to completely reorganise the way we travel, produce goods, generate energy and eat – which is what is demanded in order to eliminate carbon emissions.

Geoengineering is imperfect, says Wagner,........
