CLIMATE ONE: Small Dollar, Big Impact
The climate doesn’t care where emissions cuts come from; what matters is that the world transitions to renewable energy quickly and cheaply. If it’s significantly cheaper to install solar panels in India than on a rooftop in California, then isn’t that where they should be built? Similarly, transferring money directly to local people with the greatest stake in preserving their land can have outsized impact in conservation. Where does a climate dollar go furthest?

Charles Sumner: Conscience of a Nation
Charles Sumner is mainly known as the abolitionist statesman who suffered a brutal caning on the Senate floor by the proslavery congressman Preston Brooks in 1856. This violent episode has obscured Sumner’s status as the most passionate champion of equal rights and multiracial democracy of his time. A friend of Alexis de Tocqueville, an ally of Frederick Douglass, and an adviser to Abraham Lincoln, Sumner helped the Union win the Civil War and pass into law the Emancipation Proclamation, the Thirteenth Amendment, the Freedmen’s Bureau, and the Civil Rights Act of 1875.
In his new book Charles Sumner: Conscience of a Nation, Zaakir Tameez presents Sumner as one of America’s forgotten founding fathers, a constitutional visionary who helped to rewrite the post–Civil War Constitution and give birth to modern civil rights law. He also argues that Sumner was a gay man who battled with love and heartbreak at a time when homosexuality wasn’t accepted. And he explores Sumner’s critical partnerships with the nation’s first generation of Black lawyers and civil rights leaders, whose legal contributions to Reconstruction have been overlooked for far too long.
Join us as Tameez brings back to life one of America’s most inspiring statesmen, whose formidable ideas remain relevant to a nation still divided over questions of race, democracy, and constitutional law.

CLIMATE ONE: Batteries Now Included
The Trump administration has taken aim at green energy, but one technology has largely been left untouched: batteries to store wind and solar electricity. California alone surpassed 13GW of battery storage last year, and Texas has become the fastest growing market for the technology. But producing batteries isn’t without its downsides, especially when it comes to mining the necessary raw materials. The upside is that those materials can be recycled and reused. If the recycling technology can reach scale and price targets, the environmental impact would drop significantly. And spent EV batteries could become a grid scale storage site even without breaking down the battery packs. How soon before renewables plus batteries can power our grid 24/7?
This episode features a reported piece by Camila Domonoske that was originally broadcast on NPR’s All Things Considered on July 10, 2024

The Future of Gun Violence Prevention with Rob Bonta, David Hogg, and Leaders in the Fight for Safety
In the wake of the Parkland shooting in 2018, David Hogg and his classmates' rallying cry, #NeverAgain, echoed across the nation. Unfortunately, since that tragic event, countless other locations—the Tree of Life Synagogue, El Paso, Uvalde, Half Moon Bay and many more—have joined the heartbreaking list of mass shootings. For each of the past five years, the number of mass shootings in the United States has exceeded the number of days in the year. These tragic events have upended workplaces, schools, places of worship, communities and daily life nationwide, resulting in thousands of lives lost. In response to this epidemic, many politicians have provided little more than clichéd thoughts and prayers.
In August 2023, California Attorney General Rob Bonta released a report on gun violence that revealed the stunning statistic that 140,000 gun deaths in the United States could have been prevented over the last 10 years had the rest of the country matched California’s firearm death rate. Leading the California Department of Justice for the last three years, Bonta has pioneered the "California model of gun violence prevention." Building on his work as a state legislator, he has defended California’s leading firearms safety laws, championed robust use of the wide array of gun-prevention tools available to Californians, and established the first-of-its-kind Office of Gun Violence Prevention.
Join Parkland shooting survivor and March for Our Lives co-founder David Hogg, along with other prominent gun violence prevention leaders, for a discussion on the future of gun safety in California and the nation, moderated by Attorney General Bonta.
How has the California model succeeded, and can it be replicated across the country? Can we hold the firearm industry accountable for putting profits over people? How should we address different types of firearm violence—including community violence, mass shootings, domestic violence and suicide? What do the twin crises of violence and political gridlock reveal about our society? And where can we find hope? Learn more about your ad choices. Visit megaphone.fm/adchoices

Are We Living Inside a Video Game? Rizwan Virk on his 'Simulation Hypothesis'
Are we living in the Matrix?
Rizwan Virk—an MIT computer scientist, leading video game pioneer, entrepreneur, film producer, venture capitalist, professor, and a founder of Play Labs @ MIT—is a leading authority on simulation theory. Now he comes to Commonwealth Club World Affairs to discuss the issues raised in his new book The Simulation Hypothesis: An MIT Computer Scientist Shows Why AI, Quantum Physics, and Eastern Mystics All Agree We Are in a Video Game.
Virk says the evolution of our video games, including virtual reality, augmented reality, artificial intelligence, and quantum computing, will lead us to a technological singularity. We will reach the simulation point, he argues, where we can develop all-encompassing virtual worlds like the OASIS in Ready Player One or The Matrix—and in fact we are already likely inside such a simulation.
Though that sounds like science fiction, many scientists, engineers, and professors have given the simulation hypothesis serious consideration, including Elon Musk, Neil deGrasse Tyson, and Nick Bostrom. But philosophers of many traditions have long contended that we are living in some kind of “illusion” and that there are other realities that we can access with our minds.
Virk's work in Silicon Valley as a video game designer caused him to wonder where our technology would take us and how long it would take us to create something like the world of The Matrix—and why he’s now 70 percent certain that we’re already inside a simulation.
Whether you are a computer scientist, a fan of science fiction like the Matrix movies, a video game enthusiast, a spiritual seeker, or simply a fan of mind-bending thought experiments, come hear Virk for yourself and you might never look at the world the same way again.

CLIMATE ONE: Cause of Death: Air Pollution
In 2013, 9-year-old Ella Roberta died from a severe asthma attack. She became the first person in the United Kingdom (and possibly the world) to have “air pollution” listed as the cause of death on her death certificate. Her mother, Rosamund Adoo-Kissi-Debrah, founded the Ella Roberta Foundation and has become a global voice for clean air.
Globally, the World Health Organization says that air pollution is associated with 6 to 7 million premature deaths every year. Addressing the cause of these deaths would also go a long way to addressing climate disruption. And since talking about climate has become so politically fraught, should we reframe the conversation to focus on taking care of our air?
Highlights:
(00:00) Intro
(03:00) Rosamund shares details of Ella’s young life and her early asthma attacks
(08:00) Ella becomes first person to have “air pollution” listed as cause of death
(13:00) Rosamund’s work sharing Ella’s story and raising awareness about air pollution
(20:30) How poisonous transportation emissions are and policy tools to reduce them
(26:00) Economic development does not need to sit contrary to healthy air
(27:00) Dieselgate and the work of the True Real Urban Emissions initiative
(31:00) Extreme heat can make air pollution more deadly
(37:00) Why we shouldn’t use the term "climate change”
(43:00) Finding ways to connect with people on climate based on their priorities
(49:00) How to convey the seriousness of climate threats while also empowering people to feel that they can make a difference
(52:30) Climate One More Thing
Guests:
Rosamund Adoo-Kissi-Debrah, Founder, Ella Roberta Foundation
Sheila Watson, Deputy Director, FIA Foundation
Susan Joy Hassol, Director, Climate Communication

Hip-Hop Meditation: An Intriguing Evening of Music and Mindfulness
Join us for an unforgettable evening of insight, rhythm and discussion. Hip-Hop Meditative Mindfulness blends two worlds that would seem to be at odds—the stillness of meditation and the vitality of hip-hop. Together, they invite you into a fascinating new space for powerful spiritual practice. Coupled with a discussion of how these practices can reach people immersed in popular culture and help them find the wisdom of mindfulness and Buddhism, this will be a memorable event.
Led by Born I—a renowned meditation teacher on the Balance app, an author praised by Alice Walker, and a hip-hop artist with more than 20 million streams—our event will open with a grounding guided meditation and crystal singing bowl sound bath, followed by a discussion of healing, impermanence and street culture, drawing from Born I's experiences as a Buddhist, a father, a musician, and an author.
Born I will also discuss his new book, Lyrical Dharma: Hip-Hop as Mindfulness, and his journey from the street to spirituality.
"hell is behind uspresence and kindnessended my blindness" — Born I
Although available on live stream, this event will be best in-person. So come to the Club for this experiential event, meet Born I and your peers, and maybe even have dinner afterward at a nearby restaurant!
About the Speaker
Born I (Ofosu Jones-Quartey) is a Ghanaian-American based in Washington, D.C. He is the male voice on the popular Balance meditation app and creator of the new book Lyrical Dharma: Hip-Hop as Mindfulness (Parallax Press) and companion album Komorebi.

CLIMATE ONE: Young People Are Bringing Climate To Court. And Winning.
We’re all feeling the effects of the fossil-fueled climate crisis, but young people will not let this threat to their future go unchallenged. They’re taking it to the courts. In the last year, youth plaintiffs have had notable legal successes in Montana and Hawaiʻi, challenging that those states were violating their constitutional rights in continuing to burn fossil fuels. In Hawaiʻi, the ruling compels the state department of transportation to quickly move to a zero-emission system.
But the biggest victory may have been outside of the U.S. The small island nation of Vanuatu led the charge to ask the International Court for Justice to grant a judgement on the legal obligation of countries to fight climate change. The judgment, released in late July, stated that countries do have a responsibility to address the climate crisis. Beyond their specific claims and remedies, these numerous cases ask: What do we owe our future generations, and how will we make good on those promises?
Guests:
Vishal Prasad, Director, Pacific Islands Students Fighting Climate Change
Julia Olson, Co-Executive Director & Chief Legal Counsel, Our Children’s Trust
Rylee Brooke Kamahele, Youth Plaintiff, Navahine v. Hawaiʻi Department of Transportation

How Low Birth Rates and Longer Lifespans Could Disrupt the Global Economy
While much of the focus in Washington is on fiscal debates, there’s another growing challenge with far-reaching implications for the United States and the global economy: the “youth deficit.”
A recent report by the McKinsey Global Institute (MGI) finds that declining birth rates and aging populations could undermine productivity and living standards around the world. Unless leaders take action, “younger people will inherit lower economic growth and shoulder the cost of more retirees, while the traditional flow of wealth between generations erodes,” the report warns.
MGI director and report co-author Chris Bradley will discuss the challenge and what the public and private sectors can do to prepare for these changing demographics. Join us for this timely conversation. Learn more about your ad choices. Visit megaphone.fm/adchoices
