Economics of climate engineering

Using a cost-effectiveness analysis, a study finds that retaining solar radiation management (SRM), which involves injecting sunlight-reflecting particles into the stratosphere, as a future alternative for constraining the global temperature to 2.4° C above pre-industrial levels by 2100 could result in an economy of US $2.5-5.9 trillion between 1990 and 2049; these savings are earned even before SRM is deployed, arise from a reduction in climate change mitigation measures, and offset the costs associated with side effects of SRM. - Read at PNAS.org
