Humans have profoundly impacted the planet, ushering in the Anthropocene. Ivo Kennedy explores urban agriculture's vital role in society and individual lives. He investigates how systems, from large-scale hydroponics to community gardens, can reinvent agriculture and foster nature appreciation, even within cities.

Amid environmental crisis, Kennedy, a public health graduate student, reflects on his love for both nature and vibrant city life. He considers how urban agriculture can transform gray skylines into green spaces, helping achieve environmental sustainability in energy-demanding cityscapes. This talk was given at a TEDx event.

The energy transition is critical, with the 2020s marking a decisive decade for climate justice. As fossil fuels peak, we must rapidly scale renewables, ensuring an equitable new energy economy.

The energy transition is critical, with the 2020s marking a decisive decade for climate justice. As fossil fuels peak, we must rapidly scale renewables, ensuring an equitable new energy economy. Visionary "green" entrepreneur Danny Kennedy, founder of New Energy Nexus, proposes a "3D" clean energy future: distributed, decentralized in ownership, and democratized in control, driven by global grassroots entrepreneurship.

Kennedy, a seasoned eco-activist and clean-tech leader, co-founded Sungevity and Powerhouse. He now serves as CEO of New Energy Nexus, a global nonprofit providing funds, accelerators, and networks to advance clean energy innovation and adoption worldwide.

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.
