Architect Drew Hubbell explores the intersection of sustainable design and architectural artistry, highlighting how thoughtful, aesthetically rich structures can also embody strong environmental principles. He presents several recent projects, with particular attention to their fire-resistant strategies and materials. Against the backdrop of increasingly destructive wildfires across California, Hubbell addresses the urgent need for resilient design. He discusses practical approaches and innovative ideas for architects, designers, and homeowners seeking to build, or rebuild, with fire in mind. Drawing on his professional experience, he offers clear insights to help audiences make informed, forward-thinking decisions about creating homes that are both beautiful and better equipped to withstand fire.

The extractive linear economy and policies focused on endless growth have produced unparalleled socioeconomic inequality and the climate crisis. Communities around the world are calling for new economic models that are regenerative towards people, place, and ecosystems. Ancestral ʻŌiwi (indigenous Hawaiian) economic systems were built around people's relationships and understandings of wai (water). Kamanamaikalani Beamer, Director of the Kamakakūokalani Center for Hawaiian Studies at the University of Hawaiʻi, explores the lessons that can be drawn from the Hawaiian Ancestral Circular Economy and the resurrection of peoples' ancestral relationships to love and protect water.

Climate investor and philanthropist Tom Steyer, recipient of the 2025 Charles David Keeling Memorial Lecture, talks about the current and future state of energy. In a conversation with Scott Lewis of Voice of San Diego, Steyer argues that capitalism and policy must work together at scale, and highlights the marketplace rise of renewables like solar and EVs alongside challenges like slow fossil-plant retirement, grid constraints, and the need for longer-duration storage. He also discusses emerging options such as advanced geothermal and nuclear. The Keeling Memorial Lecure is given by a prominent member of the global change community able to speak on topics that reflect the legacy of Keeling's work. [Science] [Business] [Show ID: 41034]

Batteries have become an essential component of our daily life. They power our smartphones, laptops, tablets, and many of the cars around us. They are also key to the renewable energy transition. Building better batteries requires the design of materials whose chemical composition and structure evolve drastically on charge and discharge, yet those changes must be perfectly reversible for the device to sustain hundreds or thousands of charge-discharge cycles. Raphaële Clément, Associate Professor of Materials Department at UC Santa Barbara, explains why this is a challenging task that necessitates an atomic-level understanding of the inner workings of battery materials. Clément is working to establish materials design rules and optimize materials processing approaches to advance electrochemical energy storage. Series: "GRIT Talks" [Science] [Show ID: 41031]

The "energy transition" is actually a shift from relying on fossil fuels (like coal, oil, and gas) to using metals to generate energy. However, extracting metals has always been a significant environmental and political issue, especially for cities. This problem has been around for centuries, even ancient Roman writers wrote about it. In this program, Helen Thompson, Professor of Political Economy at Cambridge University, talks about the historic use of fossil fuels and its economic, social and environmental impacts to the transition today to extracting metals for energy, dominated by China. Thompson points out that extracting resources will always have environmental and social costs. To mitigate these risks, she says we need to find ways to reduce international competition and ecological damage. This requires acknowledging that the idea of endless progress, which was fueled by fossil fuels, has its limits. And she says we must prioritize sustainability and responsible resource management to create a better future. Series: "UC Berkeley Graduate Lectures" [Public Affairs] [Business] [Show ID: 40428]

Oil and gas are the most traded commodities on the planet; they are also the chief causes of the most grievous harm our species has yet faced, the burgeoning climate crisis. Bill McKibben is the Schumann Distinguished Scholar at Middlebury College and a founder of Third Act, which organizes people over the age of 60 to work on climate and racial justice. He examines how the export of hydrocarbons, in particular, has become an enormous threat to efforts to rein in greenhouse gasses. It explores the role that America – the world’s biggest exporter of gas – plays in this ongoing catastrophe. And it looks at the role that non-tradeable commodities – sunshine and wind – play in easing this crisis. Series: "UC Berkeley Graduate Lectures" [Science] [Show ID: 40220]

What role do oil companies have in tackling climate change? In this program, Paasha Mahdavi, Assistant Professor of Political Science at UC Santa Barbara, talks about the challenge of getting big oil to take climate change seriously. Mahdavi's research broadly explores comparative environmental politics and the political consequences of natural resource wealth. He is the author of Power Grab: Political Survival Through Extractive Resource Nationalization (Cambridge University Press, 2020), which shows how dictators maintain their grip on power by seizing control of oil, metals, and minerals production. Additional recent work includes the effects of oil-to-cash transfers on civic engagement; the political economy of fossil fuel subsidy reform; and the efficacy of policies to eliminate natural gas flaring.

How can we use raw materials to improve the environment? In this program, Susannah L. Scott, professor of chemistry at UC Santa Barbara, discusses how to efficiently use catalytic conversion of unconventional materials, such as biomass and synthetic polymers to create sustainable routes to renewable energy, fuels and chemicals.

Effective management of thermal-fluids transport has become a critical challenge in many energy, water, and electronic applications due to the increasing power density and shrinking length scales. In this talk, I will first describe our effort to manipulate multi-phase fluid motion using light-responsive surfactants. Upon illuminating droplets and bubbles with light, the surfactants at the fluid-fluid interfaces go through photo-isomerization, which changes the local interfacial tension and introduces a Marangoni flow. The resulting interfacial shear stress generates a net force on the bubble or the droplets, causing them to depart or slide along the surface. We demonstrate real-time manipulation of multi-phase fluidic systems using low intensity light which can potentially enhance phase change heat transfer. I will also describe our effort to achieve passive salt-rejecting solar thermal desalination by thin-film condensation in microporous membrane which utilizes ample three-phase contact area, salt diffusion and a low vapor transport resistance. With our design, we demonstrate continuous desalination of seawater for 7-days in one Sun with no salt precipitation. These examples demonstrate the potential of combining fundamental thermo-fluid science and advanced micro/nano engineering approaches to address many of the pressing thermal challenges in energy and water systems.

Modern slavery, which encompasses 45 million people around the world, is intricately linked to the economy, politics, violence and war, gender and the environment. In this panel discussion, Kevin Bales, professor of contemporary slavery and research director of the Rights Lab at the University of Nottingham, talks about the impact of contemporary slavery with three UC Berkeley professors, Arlie Hochschild, professor emerita, Department of Sociology, Enrique Lopezlira, Ph.D., director, Low-Wage Work Program, and Eric Stover, adjunct law professor and faculty director, Human Rights Center. Slave-based activities, like brick making and deforestation, are estimated to generate 2.54 billion tonnes of CO2 per year – greater than the individual emissions of all the world’s nations except China and the U.S. Globally, slaves are forced to do work that is highly destructive to the environment. This work feeds directly into global consumption in foodstuffs, in minerals – both precious and for electronics – construction materials, clothing, and foodstuffs. Most of this work is unregulated leading to extensive poisoning of watersheds, the clear-cutting of forests, and enormous and unregulated emissions of carcinogenic gases as well as CO2. Political corruption supports this slave-based environmental destruction and its human damage. Series: "UC Berkeley Graduate Lectures" [Humanities] [Science] [Business] [Show ID: 38615]
