David Holmgren, co-originator of the permaculture concept, authored *PERMACULTURE: Principles and Pathways Beyond Sustainability*. He challenges the belief that "green tech" can enable global "sustainable consumption," asserting that diminishing oil reserves will inevitably lead to a mandatory "energy descent" for human civilization.

Holmgren advocates for permaculture principles as the most effective framework for a peaceful societal "powering down."

David Keith reviews the science and technology of solar geoengineering, addressing the following Q’s: how effective could it be in reducing climate risks? What new risks does it entail? What is uncertain? And, finally, how could uncertainty be reduced to a substantial research program? He presents a case for integrating solar geoengineering into a 4D climate policy that includes emissions cuts, carbon removal, and adaptation.

David Keith has worked near the interface between climate science, energy technology, and public policy since ’91. He took first prize in Canada’s national physics prize exam, won MIT’s prize for excellence in experimental physics, and was one of TIME Magazine’s Heroes of the Environment. David is Professor of Applied Physics at the Harvard School of Engineering and Applied Sciences and Professor of Public Policy at the Harvard Kennedy School, and founder of Carbon Engineering, a Canadian company developing technology to capture CO 2 from ambient air to make carbon-neutral hydrocarbon fuels. Best known for his work on the science, technology, and public policy of solar geoengineering, David led the development of Harvard’s Solar Geoengineering Research Program, a Harvard-wide interfaculty research initiative. His work has ranged from the climatic impacts of large-scale wind power to an early critique of the prospects for hydrogen fuel. David’s hardware engineering work includes the first interferometer for atoms, a high-accuracy infrared spectrometer for NASA’s ER-2, the development of Carbon Engineering’s air contactor and overall process design, and the development of a stratospheric propelled balloon experiment for solar geoengineering. He teaches science and technology policy, climate science, and solar geoengineering. David is the author of over 200 academic publications with a total citation count of over 13,000. He has written for the public in op-eds and A Case for Climate Engineering.

While rights are widely understood, the corresponding responsibilities are often overlooked. David Arnot champions a "responsibility revolution" to sustain human rights and democratic ideals, urging everyone to participate.

A lifelong advocate for human rights and reconciliation, Arnot has a distinguished career. As a Provincial Court Judge, he pioneered sentencing circles for restorative justice. As Treaty Commissioner, his "Teaching Treaties in the Classroom" project was cited by the UN, and he coined the phrase "we are all treaty people." Currently, as Chief Commissioner of the Saskatchewan Human Rights Commission, he prioritizes mediation, education, and systemic advocacy over litigation.
