Gaia Masterclass: The economic impacts of climate change
Speakers: Professor Richard Tol, University of Sussex
Moderator: Farshid Mostowfi, SDTS Chairperson
Abstract:
This masterclass surveys current estimates of how climate change affects human welfare. Comparative static studies show that the modal impact of a 2.5 degree Celsius increase is equivalent to losing some 2% of income — or hundred years of global warming is about as bad as losing one year of economic growth. The uncertainty is large and skewed the wrong way. Poorer countries are much more vulnerable than richer countries. Adding omitted impacts doubles the estimate, and adding growth effects doubles the estimate again. Econometric estimates of the impact of weather shocks on economic growth suffer from fatal conceptual and statistical flaws.
