Meet David Keith. He’s a professor of physics and public policy at Harvard University. He’s a Canadian who won Canada’s national physics prize exam and who Time Magazine named one of their Heroes of the Environment in 2009. Keith sounds like — must be — a rational guy with credentials like that, right? But consider Keith’s plan to tackle climate change.
He wants to send two jets 20 kilometres up above the Earth’s surface to spray a fine layer of sulfuric acid, approximately one million tons of it, blanketing the global atmosphere.
According to an article on Smithsonian.com, which recently featured Keith, that layer of sulfuric acid would be enough to reflect back one per cent of the sun’s rays, deflecting radiation and lowering the global temperature.
The Smithsonian celebrated Keith in mid-May at its third annual The Future is Here Festival.
