    Geo-engineering to slow global warming: David Keith on TED.com


    Keith et al. (2005): “the Earth is already so transformed by human actions that it is, in effect, a human artifact.” So, what is natural and what is unnatural?

    Environmental scientist David Keith talks about a cheap, effective, shocking solution to climate change: What if we injected a huge cloud of particles into the atmosphere, to deflect sunlight and heat? As an emergency measure to slow a melting ice cap, it could work. Keith discusses why geo-engineering like this is a good idea, why it’s a terrible one — and who, despite the cost, might be tempted to use it. (Recorded September 2007 in New York City. Duration: 16:04.)
