Publication: measuring effects of geoengineering on agriculture using volcanoes by Solomon Hsiang

Jon ProctorSolomon Hsiang, and coauthors published a study in Nature estimating the effect of solar radiation management (SRM) on global agricultural production. The paper exploits the historical eruption of massive volcanoes that inject sulfate aerosols into the stratosphere to understand the effect of changing light conditions on crop yields. The paper finds that benefits from cooling, the intended effect of SRM, are fully offset by harm to yields via shading.

Publication: Social and economic impacts of climate by Solomon Hsiang

Tamma Carleton and Solomon Hsiang published an article in Science discussing and synthesizing the methods and results used to understand the impact of climate from the last decade. We demonstrate how findings across the literature and sectors are linked, identify commonalities across numerous studies, and compute how much (i) various aspects of the current climate contribute to to historical social outcomes, (ii) how much climate change to date has affected outcomes, and (iii) quantitative projections of the future. We identify that understanding "adaptation gaps" is the most important area for future research.

Publication: Conflict in a changing climate by GlobalPolicyLab Member

Tamma and Sol, along with co-author Marshall Burke at Stanford, published a review of the climate and violence literature in a Special Topics issue of the European Physical Journal.

The review focuses on how to use empirical evidence from historical climate-conflict relationships to make projections about the future. We present new evidence suggesting that income mitigates the impact of temperature on crime and conflict, implying that future projections may be improved by incorporating income-based adaptation.

Book published on economic risk of climate change by GlobalPolicyLab Member

Amir Jina, James Rising, and Solomon Hsiang were coauthors on the book "Economic Risks of Climate Change: An American Prospectus" published by Columbia University Press. The analysis in the book was the research behind the Risky Business initiative lead by Michael Bloomberg, Hank Paulson and Tom Steyer. Commentary by Karen Fisher-Vanden, Michael Greenstone, Geoffrey Heal, Michael Oppenheimer, and Nicholas Stern and Bob Ward enrich the original analysis.

Report on the Economic Risks of Climate Change by GlobalPolicyLab Member

Solomon Hsiang, Amir Jina, James Rising, and colleagues published a major report--The American Climate Prospectus--providing the first detailed assessment of the economic risks posed by climate change to the US economy. The analysis was the foundation of the Risky Business report, published simultaneously by Michael Bloomberg, Hank Paulson, Tom Steyer, and colleagues.
