摘要

This paper uses a vote-counting procedure to estimate the probability density function of the total economic impact as a parabolic function of global warming. There is a wide range of uncertainty about the impact of climate change up to 3℃, and the information becomes progressively more diffuse beyond that. Warming greater than 3℃ most likely has net negative impacts, and warming greater than 7℃ may lead to a total welfare loss. The expected value of the social cost of carbon is about $29/tC in 2015 and rises at roughly 2% per year.
