More from Shellenberger and Nordhaus on uncoupling energy policy from climate policy

Their latest piece: Freeing energy policy from the climate change debate.

Excerpts:

Environmental advocates — with help from pollsters, psychologists, and cognitive scientists — have long understood that global warming represented a particularly problematic threat around which to mobilize public opinion. The threat is distant, abstract, and difficult to visualize. Faced with a public that has seemed largely indifferent to the possibility of severe climactic disruptions resulting from global warming, some environmentalists have tried to characterize the threat as more immediate, mostly by suggesting that global warming was already adversely impacting human societies, primarily in the form of increasingly deadly natural disasters.

The result has been an ever-escalating set of demands on climate science, with greens and their allies often attempting to represent climate science as apocalyptic, imminent, and certain, in no small part so that they could characterize all resistance as corrupt, anti-scientific, short-sighted, or ignorant. Greens pushed climate scientists to become outspoken advocates of action to address global warming. Captivated by the notion that their voices and expertise were singularly necessary to save the world, some climate scientists attempted to oblige. The result is that the use, and misuse, of climate science by advocates began to wash back into the science itself.

Not everyone agrees with this assessment, as suggested recently by sociologist Bill Freudenburg and others that climate science errs in being too conservative rather than too apocalyptic.

Nevertheless, S & N want us to consider the extent to which dramatic energy policy can be rolled out in the absence of incentives like carbon taxes or cap and trade if, as they suggest, we are wasting time using science to pursue the latter:

In the end, there is no avoiding the enormous uncertainties inherent to our understanding of climate change. Whether 350 parts per million of CO2 in the atmosphere, or 450 or 550, is the right number in terms of atmospheric stabilization, any prudent strategy to minimize future risks associated with catastrophic climate change involves decarbonizing our economy as rapidly as possible. Stronger evidence of climate change from scientists was never going to drive Americans to demand economically painful limits on carbon emissions or energy use. And uncertainty about climate science will not deter Americans from embracing energy and other policies that they perceive to be in the nation’s economic, national security, and environmental interest. This was the case in 1988 and is still largely the case today.

Now is the time to free energy policy from climate science. In recent years, bipartisan agreement has grown on the need to decarbonize our energy supply through the expansion of renewables, nuclear power, and natural gas, as well as increased funding of research and development of new energy technologies. Carbon caps may remain as aspirational targets, but the primary role for carbon pricing, whether through auctioning pollution permits or a carbon tax, should be to fund low-carbon energy research, development, and deployment.
