  • ASU Researchers Tackle Extreme Heat Relief as Phoenix Temps Soar

    ASU Researchers Tackle Extreme Heat Relief as Phoenix Temps Soar
    Feb 21 2025
    Phoenix experienced a 113-day streak of temperatures at or over 100 degrees, and an annual average high temperature of 90 degrees in 2024. The city’s extreme heat is the worst in the nation and has equally resulted in staggering increases of climate-related health emergencies and deaths.

    Greater resilience to such rising temperatures requires clear, verifiable information that can guide communities in effective decision-making. Researchers at Arizona State University are working to fill this gap, using the Phoenix metro as a laboratory in which to measure, study and document the complex variables that determine thermal risk or safety for humans.

    Using novel technologies—like ANDI, the only thermal manikin in the world customized for testing outdoor environments—these scientists are building a detailed understanding of how heat affects the human body under a variety of real-world conditions. The results inform local governments' urgent heat risk mitigation work, identifying and prioritizing high-impact opportunities for public cooling center facilities and augmented built or natural shade.

    Listen in as Ten Across founder Duke Reiter the award-winning climatologist Jennifer Vanos and human thermoregulation expert Konrad Rykaczewski about progress and direction in this groundbreaking heat research at ASU, and how its results may help other heat-vulnerable cities in the I-10 corridor and beyond.

  • Investing in New Orleans' Future with GNOF CEO Andy Kopplin

    Investing in New Orleans' Future with GNOF CEO Andy Kopplin
    Feb 13 2025
    New Orleans is an extraordinary place that has experienced more than its fair share of adversity. Living below sea level where the mouth of the Mississippi River meets the Gulf Coast, residents have become adept at mitigating a variety of water-related challenges, from the inundation of tropical storms and subsidence to the scarcity issues of saltwater intrusion.

    There’s a lot we can learn from the people and leaders of New Orleans. The city's pride in its wealth of culture was on display to the nation recently in the pageantry of Super Bowl LIX. But the spirit of New Orleans may be most evident in the way the city has pioneered a model of urban resilience that addresses future social, economic, and environmental risks.

    Future-oriented action, with all its challenges, is the core focus of Ten Across and the focus of today’s episode with Greater New Orleans Foundation CEO Andy Kopplin.

    To commemorate their 100-year anniversary, the Foundation recently hosted a “Next 100 Years Challenge,” offering a $1.2 million investment in 10 different resilience project proposals across Southern Louisiana. The community has already seen significant returns on this initial investment, offering a compelling example for local and regional support of stronger communities in a changing climate.

  • Reporting on Climate Change When it's at Your Doorstep with Allison Agsten

    Reporting on Climate Change When it's at Your Doorstep with Allison Agsten
    Feb 6 2025
    Compelling communication about risks and necessary actions is of special interest throughout the Ten Across geography. As we continue to follow the course of recent wildfires in the Los Angeles area, we took a closer look at journalism on the ground-- reporters doing their best to convey urgent information at multiple and sometimes personal scales. On the heels the hottest 12 months in recorded history, parts of the Los Angeles metro burned during most of January. Ten months of abnormally dry conditions in the city were preceded by two very wet winters. Scientists refer to this increasingly common phenomenon as hydroclimate volatility or whiplash. It has been shown to be aggravated by climate change, and in Southern California, it creates the essential ingredients for large-scale wildfire. As inaugural director of the Annenberg Center for Climate Journalism and Communication at the University of Southern California, Allison Agsten’s job is to study how the news media and other communication professionals are informing audiences of climate change risks and impacts. In 2023, we invited her to share this important work and to lead our Climate Communications workshop at our Ten Across Summit in Los Angeles. Allison is, unfortunately, also a recent survivor of the Palisades Fire conflagration. As her neighborhood burned and the media converged around her home last month, she conducted some research in real time by asking them whether their reports would cover the ways climate change influenced the disaster. In this episode, we’ll hear what they had to say and what Allison believes this means for the future of climate journalism in the U.S. Related articles and resources: “What I Learned from LA Reporters Covering the Fires” (Allison Agsten, USC Annenberg Center for Climate Journalism and Communication blog) “The media needs to show how the climate crisis is fueling the LA wildfires” (The Guardian Opinion, January 16, 2025)“US Speaker suggests withholding disaster aid over California immigration policies” (9 News, January 23, 2025) “How partisan news outlets frame vested interests in climate change” (Journal of Environmental Management, February 2025) “Consuming cross-cutting media causes learning and moderates attitudes: A field experiment with Fox News viewers” (Center for Open Science, 2023) “What We Can Learn from the LA Fires with Char Miller” (Ten Across Conversations podcast, January 30, 2025) “Urban Expert Bill Fulton’s Perspective of How LA Can Rebuild Following the Fires” (Ten Across Conversations podcast, January 15, 2025) “NOAA Meteorologists Reflect on This Year’s Historic Atlantic Hurricane Season” (Ten Across Conversations podcast, November 22, 2024)

  • Past and Future Resilience Along the Mississippi with Boyce Upholt

    Past and Future Resilience Along the Mississippi with Boyce Upholt
    Jan 31 2025
    In many ways, modern American engineering was born on the Mississippi. In the early days of westward expansion, the continent’s largest river basin presented both a vital resource for transportation, biodiversity and agricultural production and a complicated barrier.

    The Army Corps of Engineers was founded in 1802, a year before the Louisiana Purchase. By the mid-1800s, Congress charged the Corps with improving transportation on the river to support the nation’s burgeoning steamboat industry and riverine settlements. Military-trained engineers were enlisted to control the river, using brute force technology, into a predictable path to prevent flooding of communities and stabilize water levels for travel.

    In the new book, The Great River: The Making and Unmaking of the Mississippi, award-winning investigative journalist Boyce Upholt questions the logic of believing it possible—or ideal—to control one of the world's largest and most powerful rivers for centuries. Taking a holistic and geologic view of the landscape, Boyce describes how the Mississippi River has continually changed paths over millennia and why this is necessary to the health of the entire delta, especially in a changing climate.

    The book offers insight into the power and the fragility of many of the ecosystems on which we rely. Listen in as Ten Across founder Duke Reiter and Boyce Upholt discuss the intersections of the built and the natural environments, and the complexities of maintaining habitable places within essential yet hazardous geographies.

  • What We Can Learn from the LA Fires with Char Miller

    What We Can Learn from the LA Fires with Char Miller
    Jan 29 2025
    Our examination of the conditions that exacerbated the Los Angeles wildfires earlier this month continues today with perspective from author and environmental historian Char Miller.

    Southern California received some much-needed rain over this past weekend, allowing firefighters to better contain the Palisades, Eaton, and Hughes fires. At the same time, the burned hillsides now bear much greater risk of mudslides and floods.

    These communities and individual residents must make complicated decisions about how to securely rebuild for the future. California Governor Gavin Newsom and Los Angeles Mayor Karen Bass have both advocated for eliminating some regulatory hurdles to help fast-track the reconstruction of Pacific Palisades and Altadena.

    Having carefully studied California’s fire history, Char argues that haste could lead to repeats of the same land use, zoning, and construction mistakes that have increased residential fire risk across the state to begin with.

    Climate change aside, land use policies that discount long-term environmental awareness are common contributing factors in nearly every type of disaster risk found in the Ten Across geography. Listen in as Ten Across founder Duke Reiter talks with Char Miller about the developing events in Los Angeles and how they relate to many other risk and adaptation stories across Interstate 10 in recent history.

  • Is Sharing Our Climate Emotions Key to Achieving Climate Action?

    Is Sharing Our Climate Emotions Key to Achieving Climate Action?
    Jan 23 2025
    In the hottest year in recorded history, extreme heat corresponded to several notable weather events and ongoing public health impacts in the Ten Across geography. Evidence shows warming ocean temperatures were behind an especially destructive Atlantic hurricane season for the Gulf. Nearly all states along this transect saw their rates of private insurance nonrenewal increase among the most at-risk communities, as a result of storms, wildfires and other extreme weather. Lastly, all but four US cities that saw the most significant jump in their number of extremely hot days last year are along Interstate 10.

    It would not be unreasonable to feel some uneasiness and uncertainty as the new year begins. We are living in a fast-paced, highly connected period of volatility for humanity at large. And many of the decisions and actions taken now will have more immediate consequences here in the Ten Across geography, where the evidence of climate change is felt most profoundly.

    A loss of insurance or homeownership; loss of recreation or thermal comfort due to extended heat waves; or loss of communities as we once knew them from disaster, places a significant mental toll on those in the immediate and surrounding environment, as well as observers. However, a study by George Mason University finds most Americans (65%) ‘rarely’ or ‘never’ talk about the topic of climate change with friends or family.

    In this episode, Ten Across founder Duke Reiter and Dr. Sophie Nicholls, principal investigator for the Feeling Planet research study, discuss the importance of naming and reflecting on difficult feelings about our environment. Sophie’s study seeks to demonstrate how this process is critical in tending to ourselves and others, and for generating action and hope for the future.

  • Ten Across Conversations 2024 Major Takeaways

    Ten Across Conversations 2024 Major Takeaways
    Jan 17 2025
    The events of the past year have reinforced the logic of the Ten Across initiative. In the context of the hottest year in recorded history, the Ten Across geography witnessed ongoing drought, a supercharged Atlantic hurricane season, devastating wildfires, and a significant loss of homeownership or insurance safety nets for its residents. As we enter 2025, with staggering urban wildfires still raging in the Los Angeles area and a new federal administration soon to be sworn in; it is evident that this year will be a complex, unpredictable, if not historic year. This underscores the urgency of continuing our dialogues and collaborations on climate resilience. We believe the Ten Across region holds critical insights to understanding our present challenges and the foreseeable future as a nation as climate change and other global forces converge. In this episode, we contextualize major issues surfaced in 2024 and their significance within our region to set the stage for conversations in the year ahead. While we cannot highlight every guest and topic, we would like to sincerely thank all who engaged with us and shared their insights last year. We hope this summary will inspire you to revisit and share some of your favorite conversations of the show, so that we may connect with more of you in the new year.

  • Urban Expert Bill Fulton's Perspective on How LA Can Rebuild Following the Fires

    Urban Expert Bill Fulton's Perspective on How LA Can Rebuild Following the Fires
    Jan 15 2025
    On January 10, a sudden urban fire began in Los Angeles’s Pacific Palisades neighborhood, immediately scorching 200 acres. Two hours later, evacuations were ordered for the 23,000 people in the community. By morning, all Los Angeles firefighters were called to duty, prepared for the worst as 50 to 80-mph winds began to pick up and carry embers from the fire for miles.

    Then the worst happened—firefighting aircraft became grounded due to the strong Santa Ana winds and hydrants, not designed for a fire of this scale, ran dry after constant use for 24 hours leaving homes and first responders defenseless. Within a short period of time, the Palisades fire razed 5,000 structures and counting to the ground.

    A little over a week since the blaze began, the Palisades and nearby Eaton fire in the Angeles National Forest, remain largely uncontained. Smaller fires in the conflagration—including Hurst and Kenneth on the northeast side of LA—are nearly or 100% contained. However 90,000 residents remain under evacuation orders and another 84,000 are under a warning. Life has come to a standstill in this portion of the nation’s second largest city and the path to recovery is uncertain.

    For years, the insurance industry has been anticipating an event like this. In fact, just last summer, 70% of Palisades residents had their home policies dropped because companies determined wildfire rebuilding cost would be insurmountable. The absence of private insurance coverage, and the speed with which the fire consumed billions of dollars’ worth of property, has raised urgent questions about how and where we will choose to develop housing, businesses, and necessary institutions in a climate changed world.

    In this timely episode, Ten Across founder Duke Reiter and Bill Fulton, the former mayor of Ventura, California and former director of planning and economic development for the City of San Diego, discuss the future of homeownership, insurance, and residential development in Los Angeles while this singularly tragic event continues to play out.
