That lack of data had a lot to do with the venue in which this talk was given. At TED conferences the speakers are only allowed 18 minutes, just enough time to present an idea. But his methodology and data didn't need to be presented because he wasn't actually trying to explain how to geoengineer the planet. The focus of his talk was that the taboo subject of geoengineering should be pulled out of the closet, discussed publicly and actively investigated by more climate scientists, possibly with government funding.

I was intrigued by this talk because he questioned many of the assumptions people make about global warming, primarily the the one that global warming is bad for everyone. What was so damn great about the global climate 200 years ago anyway? And if we can reverse global warming, should we really make it that cold again? People don't ask these sorts of questions nearly often enough and it's a good sign when scientists ask them. Hopefully more people will actually think about the answers to those questions instead of simply assuming that preindustrial temperatures are preferable.

Here's a link to the Economist article he referenced in his talk.
