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.

The national uprising following George Floyd's murder has underscored systemic racism and its impact on environmentalism, where communities of color face disproportionate climate burdens yet are often excluded from solutions. Join us for a vital conversation on amplifying leaders of color in climate action and building an inclusive, anti-racist green movement.

Speakers include Mustafa Santiago Ali (National Wildlife Federation), Robert Bullard (Texas Southern University), and Glynda Carr (Higher Heights for America), hosted by Greg Dalton.

Climate experts emphasize the urgent need to act on global warming, noting only 13-20 years remain before critical thresholds are reached. Immediate focus must be on carbon removal and implementing "zero" solutions across key sectors: zero-emission electric grids, transportation, buildings, and waste manufacturing. This collective effort is essential to turn the tide.

Addressing climate change demands substantial funding, yet philanthropic strategies face scrutiny. Critics argue major organizations often underfund grassroots initiatives, movement building, and vulnerable communities most impacted by climate change. True progress, as emphasized by Farhad Ebrahimi, requires broad community engagement. Learn more at climateone.org.
