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.

During SF Climate Week, Climate One hosted 2025 Goldman Environmental Prize winners Laurene Allen and Carlos Mallo Molina. These inspiring leaders protect their communities from powerful interests, often at great personal risk. Join Co-Host Greg Dalton to explore their extraordinary actions.

Carlos Mallo Molina led a campaign to stop Fonsalía Port construction, canceled in October 2021. The terminal threatened a 170,000-acre marine protected area in Tenerife, home to sea turtles, whales, and sharks. He now envisions a marine conservation and education center.

Laurene Allen protected New England families from PFAS-contaminated drinking water. Her campaign pressured an industrial giant, responsible for toxic "forever chemicals," to close in May 2024, ending over 20 years of pollution.

John Doerr, venture capitalist and author of the best-selling book *Measure What Matters*, popularized OKRs (objectives and key results). Now, in *Speed & Scale: An Action Plan for Solving Our Climate Crisis Now*, Doerr and Kleiner Perkins advisor Ryan Panchadsaram argue that the same management tools can be applied to prevent the growing climate crisis.

Join The Commonwealth Club and Climate One on December 6, 2021, as John Doerr and Ryan Panchadsaram discuss this pressing issue. They will explore how lessons learned at the highest levels of business might address climate change, in conversation with Greg Dalton of Climate One.

Amid global crises—climate change, ecocide, declining biodiversity, social inequity, injustice, and political turmoil—Indigenous lifeways and values offer a path to a better future. Core Indigenous values like relationship, responsibility, reciprocity, and redistribution guide us to be good stewards of our communities and ecosystems. Birds, our feathered relatives, provide valuable insights into these principles. Join the conversation.

Our panelists are Aimee Roberson (Cultural Survival Executive Director), Ruben Flores (CS Bazaar Artist), Kim Tekwitha Spencer (CS Youth Fellow), and Israel Hernández López (KOEF Grant Partner). Interpretation is available: tinyurl.com/lifeways1120.

"Health as a Social Movement" is a three-year NHS England-funded program. It aims to understand and support social movements in health and care, working with New Care Model vanguards and national partners (The RSA, New Economics Foundation, Nesta). The program develops and spreads effective ways to mobilize people, improving health and care outcomes with a positive return on investment.

The animation, "More Than a Pill," sponsored through the RSA Student Design Awards, clarifies and illuminates the ideas behind creating a social movement for health. It was voiced by Nathalie Spencer, with thanks to Matthew Stidwill.

Rapid decarbonization of Western lifestyles is essential to avoid catastrophic climate change. This talk, based on the EU-funded CityZEN project, outlines a methodology to engage communities in envisioning a shared, carbon-free future. By visualizing individual carbon footprints, design interventions can transform consumption across urban space, mobility, and energy, creating bio-diverse, prosperous, and connected neighborhoods.

Greg Keeffe, Professor of Sustainable Architecture at Queens University Belfast, is an academic and urban designer with over 30 years' experience in sustainability. He develops innovative solutions for urban revitalization and theoretical hypotheses for our future existence. This presentation was delivered at a TEDx event. Learn more at ted.com/tedx.
