In the 1970s, the Yale economist William Nordhaus began constructing a model meant to gauge the effect of warming on economic growth. The work, first published in 1992, gave rise to a field of scholarship assessing the cost to society of each ton of emitted carbon offset by the benefits of cheap power — and thus how much it was worth paying to avert it.
Dr. Nordhaus became a leading voice for a nationwide carbon tax that would discourage the use of fossil fuels and propel a transition toward more sustainable forms of energy. It remained the preferred choice of economists and business interests for decades. And in 2018, Dr. Nordhaus was honored with the Nobel Memorial Prize in Economic Sciences.
