The cost of stratospheric aerosol injection through 2100

Published: October 2020 by Environmental Research Letters

Summary: A follow up to the 2018 paper wherein the aeronautical tactics and costs required to implement a hypothetical stratospheric aerosol injection program are calculated through the end of the century to give a more complete picture of costs.  A range of emissions pathways is considered, as is a range of cooling targets, such that a spectrum of possible program sizes may be evaluated.
