The Intergovernmental Panel on Climate Change has assumed Nordhaus is to be trusted. The integrated assessment models used at the IPCC are based on Nordhausian visions of adaptation to warming that only marginally reduces global gross domestic product. If future GDP is barely affected by rising temperatures, there’s less incentive for world governments to act now to reduce emissions.

Andrew Glikson, who teaches at Australian National University in Canberra and advises the IPCC, has written about the coming era of mass human death, what he calls the Plutocene, the natural successor to the Anthropocene. Global governments, he charges, are “criminals” for ushering in the Plutocene in pursuit of short-term political and economic gain. I first reached out to him during the black summer of bushfires that raged across Australia in 2020. Glikson’s mood was foul then, and it has not gotten better since.

“The governing classes have given up on the survival of numerous species and future generations,” he told me, “and their inaction constitutes the ultimate crime against life on Earth.” Part of the reason for inaction is the false cheer that Nordhaus has spread with his math-genius, climate-idiot models.
