FCEA Blog: Cost-Benefit Analysis of Solar Geoengineering

By Juan Moreno-Cruz, and Soheil Shayegh. „Solar geoengineering (SGE) offers the possibility of offsetting greenhouse-gas-induced temperature increases by reducing incoming solar radiation. Its key advantages are 1) it is fast. Unlike emissions reductions, which can take decades to bear results, SGE can reduce global temperatures nearly instantaneously. 2) it is cheap. SGE can potentially reduce temperatures at costs that are several orders of magnitude lower compared to abatement – this has been called “the incredible economics of geoengineering”.“
