Environmentalist and author Bill McKibben has helped shape how the world understands climate change. In this conversation with Marco Werman, host of The World, McKibben offers a clear-eyed look at the climate crisis and the solutions that could help reduce the damage of a warming planet. As part of the Burke Lectureship at UC San Diego, McKibben also explores the moral and spiritual questions at the heart of climate change. More than three decades after The End of Nature brought climate change to a broad audience, his work continues to connect science, ethics, and grassroots action, including the global climate campaign 350.org and the fossil fuel divestment movement.

How does global warming connect to the extreme weather people experience close to home? Drawing on the work of the Weather Extremes and Climate Impacts Analytics group, Sasha Gershunov of Scripps Institution of Oceanography outlines the accelerating warming trend, the role of fossil fuels and carbon dioxide, and the greenhouse effect, and how it relates to extreme weather. He also traces key milestones in climate science, including the long-term carbon dioxide measurements begun by Charles David Keeling. The discussion then turns to how climate change may affect heat waves, floods, droughts, storms, wildfires, and sea level rise.

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]

For many people, a personal connection to the ocean ties into bigger issues like conservation and climate change. As the biodiversity of marine life along the coast at La Jolla Shores has declined, divers and researchers discuss why simply knowing about environmental problems isn’t enough. They emphasize the importance of conservation psychology, storytelling, and inspiration to encourage action. This video was created by graduate students in Marine Biodiversity & Conservation at Scripps Institution of Oceanography, UC San Diego. [Science] [Show ID: 41072]

Coastal Santa Barbara is considered one of the most idyllic locations on the North American West Coast, but its beauty is frequently disrupted by fast-spreading, wind-driven wildfires. The east-west oriented Santa Ynez Mountains (SYM), rising abruptly over 1,000 meters from the coastal plain, create a distinct climatic environment by separating the cool, stable air over the Pacific from the much drier atmosphere of the Santa Ynez Valley. This topography leads to unique regional wind patterns, including the Sundowner winds, which occur along the southern slopes of the SYM. Leila Carvalho, Professor of Geography and a researcher at the Earth Research Institute at UC Santa Barbara, studies regional and large-scale climate variability and change, including monsoon dynamics, tropical-extratropical interactions, extreme precipitation and temperature events, mountain weather and climate, and regional modeling.

Three major global challenges – climate change, loss of biodiversity and its benefits, and inequality and inequity among people – are typically tackled within three separate silos. However, scientific knowledge tells us that the three are inextricably linked. If the problems are not considered together, solutions to one may undermine solutions to the others. Moreover, more holistic, integrated solutions can deliver multiple co-benefits. Success requires integrated solutions. Jane Lubchenco, Professor of Marine Biology at Oregon State University, talks about the historically ambitious, innovative policies implemented by the Biden-Harris Administration to achieve this integration. Lubchenco is a marine ecologist with expertise in the ocean, climate change, and interactions between the environment and human well-being. From 2021-2025, she served as Deputy Director for Climate and Environment in the White House Office of Science and Technology Policy.

The meteorology that causes atmospheric rivers is complex, but scientists at the Center for Western Weather and Water Extremes (CW3E) are working to help better predict them and understand what they mean for rainfall and snowfall across the state. Join CW3E Deputy Director Julie Kalansky to learn the causes and consequences of these rivers in the sky. Series: "Jeffrey B.

We are at a critical moment in our society. While we advance efforts to mitigate and adapt to the climate crisis, across the globe, millions are experiencing issues of energy affordability, reliability and equitable access to modern energy technologies. In this program, Tony Reames, Professor of Environmental Justice at the University of Michigan School for Environment and Sustainability, explores the intricate intersection of energy, class, race and place, shedding light on inequities in access to and the distribution of energy resources. Reames discusses how various factors, including socio-economic conditions, policy landscapes and environmental characteristics contribute to energy inequities. The talk underscores the importance of understanding and addressing these issues in the pursuit of energy justice, emphasizing the need for inclusive scholarship, policies and funding that empower marginalized communities.
