Dr. Quinton's talk, "Dinosaurs, Asteroids, and Climate Change," explores the connections between climate change, asteroid impacts, and dinosaur extinction. She discusses predictions regarding how an asteroid alters Earth's climate, emphasizing that these have not been empirically tested and thus require a creative experimental approach.

Page Quinton is an Assistant Professor of Geology, teaching courses such as Principles of Paleontology, Geochemistry, and Climate Change: Past and Present. This presentation was given at an independently organized TEDx event. Learn more at https://www.ted.com/tedx.

Physicist Michio Kaku argues humanity faces an extinction threat from Mother Nature and the laws of physics, making space travel our ultimate destiny. Citing Isaac Asimov's question and the 99.99% extinction rate of species, Kaku believes our survival depends on exploring beyond known physics.

The future energy system will be 100% renewable, a goal potentially achievable sooner with the right incentives. Yet, simply adopting renewables isn't sufficient. Our technology must be designed

The future energy system will be 100% renewable, a goal potentially achievable sooner with the right incentives. Yet, simply adopting renewables isn't sufficient. Our technology must be designed for repair, reuse, and multiple cycles to ensure true sustainability.

Join our studio guests to explore the opportunities and risks of this renewable transition. We will also feature Professor Lou Yongqi of Tongji University, a leading circular designer from China, who will discuss how new design principles can reshape one of the world's largest economies.

New Yorker writer Eliza Griswold and UC Berkeley professor Arlie Hochschild traveled to "Trump country" to challenge stereotypes and understand environmental perspectives beyond the "red state, blue state" divide. Griswold explored fracking's impact in Pennsylvania, while Hochschild immersed herself in rural Louisiana. Both emerged with honest portraits of a misunderstood America.

The discussion also covered the U.S. fracking boom, which has made the country the world's largest oil producer. Bethany McLean's book, *Saudi America*, examines fracking's past, present, and future. However, this fossil fuel expansion conflicts with Paris climate accord goals, prompting questions about the future of energy. Learn more at climateone.org.

John Holdren, a Harvard professor of environmental science and policy, believes that addressing climate change is a solvable challenge.

However, he suggests the Green New Deal might overcomplicate these efforts if it simultaneously pursues ambitious goals such as universal jobs, education, and healthcare.

John Hearin, Ph.D., explores the critical importance of our world's beaches as cultural treasures and vital economic engines. He will explain common methods for protecting these essential resources and how our decisions literally shape the shoreline.

Dr. Hearin, who grew up in Daytona Beach, holds M.S. and Ph.D. degrees in Ocean Engineering from the Florida Institute of Technology, where he also served as an Assistant Research Professor. With over 15 years of active involvement, he currently chairs the Cocoa Beach chapter of the Surfrider Foundation.

Liberal democracy faces significant threats from rising populism and its struggle to address complex societal challenges, including the climate crisis. This necessitates bold, radical ideas for both policy solutions and the processes required to implement change, especially concerning economic growth expectations.

Caroline Lucas MP and Professor David Runciman will explore diverse approaches to these multifaceted concerns. They will specifically consider whether deliberative processes can effectively engage citizens in political decision-making, thereby strengthening representative democracy.

Pueblo people have a 400-year history of sustainability and self-reliance, a tradition disrupted by Spanish land policies. Today, they are actively working to restore these vital practices within their communities.

Greg Cajete, a Tewa Indian from Santa Clara Pueblo, New Mexico, is a leading voice in this effort. He serves as Director of Native American Studies and an Associate Professor at the University of New Mexico, holding a Ph.D. with an emphasis in Native American Studies.

Visit UCTV to learn about the far-reaching impacts of fracking, including premature births, unexplained illnesses in humans and livestock, flammable water, toxic wells, and increased earthquakes.

Professor Sara Wylie (Northeastern University) connects fossil fuels to climate change and endocrine disruption, discussing strategies to resist the combined toxicities of the fossil fuel and petrochemical industries. She also explores developing alternative public interest databases and environmental health research tools.
