Breakthrough Institute co-founders Michael Shellenberger and Ted Nordhaus returned to Yale University last month for a retrospective on their 2004 essay, “The Death of Environmentalism.” Rarely does a critical assessment of an inflamed public debate so clearly shine the light of reason on why a cause was lost. In their speech Shellenberger and Nordhaus, bloth life long environmentalists, argued that green politics and the climate change crisis were destroyed from within, by exaggerated scientific claims, fantasies about green jobs and “An Inconvenient Truth.” After detailing how climate change alarmists managed to snatch defeat from the jaws of victory, the authors go on to offer some advice for the green movement: 12 theses for a post-environmental approach to climate change. In effect, they are saying that the world needs to concentrate on solving the problems that matter to people—food, energy, economic development—and the environment will be fixed as a side effect.
