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.
