Inconvenient truths for the environmental movement

By Joshua S. Goldstein and Steven Pinker. Joshua S. Goldstein is emeritus professor of international relations at American University and a research scholar at the University of Massachusetts Amherst. Steven Pinker is professor of psychology at Harvard University and the author of “The Better Angels of Our Nature.” Excerpts:
"The first is that, until now, fossil fuels have been good for humanity. The industrial revolution doubled life expectancy in developed countries while multiplying prosperity twentyfold. As industrialization spreads to the developing world, billions of people are rising out of poverty in their turn — affording more food, living longer and healthier lives, becoming better educated, and having fewer babies — thanks to cheap fossil fuels."

"Nuclear power is the world’s most abundant and scalable carbon-free energy source. In today’s world, every nuclear plant that is not built is a fossil-fuel plant that does get built, which in most of the world means coal. Yet the use of nuclear power has been stagnant or even contracting."

"Nuclear today is relatively expensive, but that is largely because it must clear massive regulatory hurdles while its fossil competitors have been given relatively easy passage. New fourth-generation nuclear designs, a decade away from deployment, will burn waste from today’s plants and run more cheaply and safely."

"Without nuclear power, the numbers needed to solve the climate crisis simply do not add up. Solar and wind are growing quickly, but still provide about 1 percent and 4 percent respectively of electricity production, and cannot scale up fast enough to supply what the world needs. Moreover, these intermittent energy sources could power the grid only with big advances in battery technology that are still in the basic-science stage. Even with them, we must not triple-count the energy promised by renewables: they cannot supplant existing fossil fuel use and replace decommissioned nuclear plants and meet the skyrocketing needs of the developing world."

"These arguments have been forcefully made by pragmatic environmentalists such as James Hansen and Stewart Brand."

"The second priority is carbon pricing: charging people and companies to dump their carbon into the atmosphere. Economists across the political spectrum agree that such a price would incentivize conservation, decarbonization, and R&D far more effectively than regulating specific industries and products (to say nothing of sermonizing for a return to an abstemious preindustrial lifestyle). Without carbon pricing, fossil fuels — which are uniquely abundant, portable, and energy-dense — simply have too great an advantage. Yet despite a strong campaign by Citizens’ Climate Lobby, a policy that ought to be a no-brainer has yet to catch on with politicians or the public."
