This document builds on an earlier map of Earth Systems Experimentation published in 2012. That original map documented almost 300 projects and experiments related to the field of geoengineering. Five years later over 800 such projects can be identified. These include projects in Carbon Capture, Solar Radiation Management, Weather Modification and other approaches.
Who Funds and Who Pays: The funding of solar geoengineering, 2020–2025
This report by Jared Sanborn and J. P. Sapinski, published by the Heinrich Böell Foundation, analyses the period from 2020 to 2025, and shows that funding for high-risk solar geoengineering technologies has increased dramatically - more than tenfold. Both 2024 and...
