Our report is an introduction to the concept of space-based geoengineering, or a planetary sunshade.
A sunshade could complement existing efforts to mitigate the climate crisis. The report is intended for policy makers who are discussing climate overshoot scenarios.
The United States of America can play a unique role in mitigating the climate crisis. We recommend this version of our report for US audiences.
