From John Holdren’s 7/7 Harvard Talk: Global Warming: What do we know and should do.

“I actually thought the biggest shortcoming in Kyoto achetecture, besides focusing on absolute reductions from 1990 which has a lot of problems, was that if focused altogether too much on targets and not enough on mechanisms. …in a way, focusing on exactly where you need to be by exactly what time is not as important as figuring out what you’re going to do to bend the curve away from this business as usual growth that we’re now on.”

“This climate change challenge is certainly one of the most interdisciplinary problems that society has ever faced in the way it links and requires understandings from science, from engineering, from economics, from policy analysis, from politics, in order to understand both what is needed and how to get there.”
