Climate econometric models indicate solar geoengineering would reduce inter-country income inequality

Abstract

Exploring the heterogeneity in impacts and outcomes of using solar geoengineering to counteract global warming is important. Here the authors found that solar geoengineering that reduces temperature below present-day would grow GDP by accelerating economic development in tropics, but projections for global GDP-per-capita by the end of the century are highly dispersed and model dependent.
