Economists have been examining the effect of climate change for almost as long as it has been known to science.
In the 1970s, 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.
