David Keith reviews the science and technology of solar geoengineering, examining its potential to reduce climate risks, associated new risks, and current uncertainties. He proposes integrating solar geoengineering into a comprehensive 4D climate policy, which includes emissions cuts, carbon removal, and adaptation.

A distinguished expert, David Keith is a Harvard Professor of Applied Physics and Public Policy. He founded Carbon Engineering, a company developing technology to capture CO2 for carbon-neutral fuels. Best known for his work on solar geoengineering, he led Harvard's Solar Geoengineering Research Program. He has authored over 200 academic publications and "A Case for Climate Engineering."

The session was moderated by Greg Bronevetsky.

In her reflection titled "Disconnection," Julia Butterfly Hill introduces "separation syndrome" as the fatal consequence of severing our ties to life. She illustrates this by noting that a plant dies when its roots are ripped from the earth, mirroring how humanity perishes when we detach from our connected consciousness.

Hill argues that this profound disconnection leads to the demise of our planet, our human families, and the entire global family. Her message underscores the critical importance of recognizing and nurturing our interconnectedness for collective survival.
