Geo-Engineering: “Comparatively Inexpensive”
Compared to what? We wonder.
Researchers in the US have estimated that modification of stratospheric albedo – a widely discussed geoengineering technique to counteract some of the effects of climate change – could cost as little as $5bn a year.
“That’ll be upfront, in our swiss bank account if you don’t mind… sign here.”
“Now, technology and policy expert Jay Apt of Carnegie Mellon University in the US and colleagues have put a price on such aerosol pumping. Using statistical methods, they estimated the cost for various systems of delivering between one and five million tonnes of particles such as sulphur compounds to altitudes of 18–30 km. These systems included the use of existing aircraft, the procurement of new aircraft or airships, the procurement of rockets and guns, and suspended gas pipes.”
