This talk explores Sunset Crater, Arizona's youngest volcano, erupted 940 years ago, impacting the Sinagua people. Geologist Dr. Jeffrey Meyer will share its story and his work mapping the unique Bonito lava flow, notable for traveling uphill.

Understanding this flow aids hazard prediction and interpreting past flows on Earth, the Moon, and other planets. Dr. Meyer, a retired geology instructor, became curious about the Bonito flow, leading to detailed mapping via Lidar.

In an increasingly urbanized and digitized world, many people are disconnected from nature and lack a deep understanding of climate change's profound impacts, despite early warnings from melting glaciers. This growing disconnect highlights an urgent need for action.

Young activists are taking charge of their climate future. High school student Isha Clarke gained fame confronting Senator Dianne Feinstein, advocating for truth to power and criticizing politicians' inaction. Similarly, 14-year-old Sarah Goody organized a climate strike, questioning the value of studying for a future that may not exist. These young voices, alongside others joining organized movements, are fighting urgently for their future.

After the 2020 wildfires, Kyle Trefny became a wildland firefighter, connecting with peers passionate about transforming society's relationship with fire. This led him to co-found FireGeneration

After the 2020 wildfires, Kyle Trefny became a wildland firefighter, connecting with peers passionate about transforming society's relationship with fire. This led him to co-found FireGeneration Collaborative (FireGen) in 2022. FireGen is a youth-led organization dedicated to shifting wildfire management from short-term disaster response to long-term resilience and Indigenous leadership.

Trefny co-led FireGen's national campaign, advocating for youth roles in policy. This resulted in FireGen members advising a federal commission and Director Ryan Reed becoming the youngest federal advisor in US history. Trefny has also been instrumental in shaping FireGen's vision and securing over $350,000 in grants, empowering youth and Indigenous voices for the future.

Humanity faces a critical climate crisis, with only about nine years to halve global CO2 emissions by 2030. While digitalization profoundly shapes our lives, its potential role in climate policy

Humanity faces a critical climate crisis, with only about nine years to halve global CO2 emissions by 2030. While digitalization profoundly shapes our lives, its potential role in climate policy for achieving this rapid reduction remains largely unexplored.

Nick Nuttall, International Strategic Communications Director for Earth Day Network and We Don't Have Time, and a UN veteran, emphasizes digitalization's opportunities for sustainable development. He views digital technology as a vital tool against climate change, citing examples from ocean clean-up to renewable energy. However, Nuttall warns against seeing it as a cure-all, stressing that digitalization must be used wisely to be effective.

Nuttall's insights were shared at a TEDx event. Learn more at ted.com/tedx.

Over the past 20 years, youth incarceration has plummeted by 75% as states closed prisons and reformed policies. In her new book, *In Our Future We Are Free*, journalist Nell Bernstein dissects this transformation. She chronicles the forces that moved us from a "moral panic" to a time when youth prisons are rapidly fading.

Bernstein's book highlights the pivotal role of imprisoned youth, mothers, activists, and even prison officials in challenging the "racist brutality of youth prisons" and closing institutions. Join Nell Bernstein and moderator Chesa Boudin to learn how this coalition reformed a "racist and destructive institution" and what other social movements can learn from their struggle.
