We examine the treatment of climate damages in the FUND model. By inserting software switches to turn individual features on and off, we obtain FUND's estimates for 15 categories of damages, and for components of the agricultural category. FUND, as used by the U.S. government to estimate the social cost of carbon, projects a net benefit of climate change in agriculture, offset by a slightly larger estimate of all other damages. Within agriculture there is a large benefit from CO2 fertilization, a moderate cost from the effect of temperature on yields, and a much smaller impact of the rate of change.
