Ted Nordhaus Deconstructs Degrowth
from Decouple · host Dr. Chris Keefer
I am joined by returning guest and co-founder of The Breakthrough Institute, Ted Nordhaus, to discuss degrowth as a proposed solution to climate change and other environmental issues. Nordhaus has written forcefully against the idea of degrowth, which posits that growth in human populations and consumption levels will inevitably bring us to the brink of what this planet can sustain. The only way to avert catastrophe is to therefore reduce human populations and minimize consumption. Nordhaus’s objections are epistemological as well as pragmatic. While degrowth risks stalling innovation and adaptation in the face of climate change, it is unclear that the proclaimed limits to human consumption (at the root of degrowth thought) are actually knowable or would even be met in the normal course of human development. Nordhaus points out the difficulty of defining the line between necessity and luxury, and argues that there is no actual science or evidence behind claims that we are approaching or have passed “planetary boundaries.” Nordhaus emphasizes that he cares about the environment and other species, but that there are “non-apocalyptic reasons to protect nature.” As for what society should do to address the climate crisis and other environmental issues, Nordhaus offers a decision-making framework that acknowledges the vast uncertainties of any future scenario: Do more of the stuff that brings us in a direction we want to go, and less of the stuff that doesn’t. To Nordhaus, foretelling disaster based on what he says are unscientific limits to growth is “an authoritarian claim” that at best leads to regressive policies and at worst creates self-fulfilling prophecies. We go on to discuss the common use of WW2 as a metaphor for the scale of climate action needed, and contrast it with a Cold War metaphor that yields more technological optimism. Finally, we touch upon a concept near and dear to this podcast: decoupling. Read Ted Nordhaus's commentary on Vaclav Smil here: https://www.thenewatlantis.com/publications/must-growth-doom-the-planet
