The Ongoing Multi-Decadal Colorado River Crisis: a collision of 19th Century Water Law, 20th Century Infrastructure, and 21st Century Climate Change and Population Growth.
The Colorado River supplies water to over 40M people in seven states, two nations and 30 Indian Tribes. Every major Southwestern city including Denver, Phoenix, Tucson, Los Angeles, Las Vegas, Albuquerque and many others rely on the river for up to 90% of their water supplies. Since 2000, river flows have declined by nearly 20% compared to the 20th century, and the nation’s two largest reservoirs have plummeted from nearly 95% full to about 25% full. A large snowpack and resulting runoff in 2023 will buy the system a ‘grace year’ but otherwise will do little to change the fundamental water management problems due to the ongoing ‘aridification’ and water overuse in the American Southwest. What does this mean for Coloradans?

Wildland fires and weather are coupled through complex feedbacks including forest and wildfire management practices, human encroachment into wildland, and the effects of climate change.
Wildfire is a fundamental component of ecosystems which humans have used to manage landscapes throughout history. In recent decades, the destructive impact of wildfires has increased significantly in the United States and across the world. This increase arises from several factors, including forest and wildfire management practices, human encroachment into wildland, and the effects of climate change on weather and vegetation. Wildland fires and weather are coupled through complex feedbacks.
Wildland fire prediction is a critical component of effective risk assessment, fire management and decision support.

The Colorado Fossil Discovery that Rocked the World
Dr. Tyler Lyson is curator of vertebrate paleontology at the Denver Museum of Nature & Science. Dr. Ian Miller is Curator of Paleobotany and Director of Earth & Space Sciences at the Denver Museum of Nature & Science.
Sixty-six million years ago a 6-mile wide asteroid slammed into Earth and caused the extinction of more than 75% of life on Earth. Dr. Lyson and Dr. Miller explained how and when life rebounded in the aftermath of the extinction based on past fossil records and a new discovery east of Colorado Springs which contains a remarkably complete fossil record of mammals, turtles, crocodiles, and plants.

Pastor John Pavlovitz
May 16, 2019-Cultivating Hope and Creating Community: A Compassionate Guide for Difficult Days
To be compassionate is to bleed, to feel deeply for the damage around you and to be moved to respond to it. This is a beautiful and invaluable instinct, but it is costly, too. There is a toll the trauma of the world takes on us when we seek to step into that dangerous space and to work for healing and justice. In days when so much need is at our doorsteps and on our news feeds, how do we attend to it all without becoming overwhelmed and consumed by it? How can we cultivate hope when it is hard to come by?
John Pavlovitz is author of A Bigger Table: Building Messy, Authentic, and Hopeful Spiritual Community and Hope and Other Superpowers: A Life-Affirming, Love-Defending, Butt-Kicking, World-Saving Manifesto. Please join us for a time of authentic conversation on how to be safely burdened with the pain of this world and what to do when you have exhausted your resources.

Colorado’s 14ers: Balancing recreational Use and Environmental Protection on America’s Approachable Everests
Colorado has more than 53 mountains over 14,000 feet in elevation (popularly known as the “14ers”) that draw hikers and climbers from across the globe. These peaks possess rare and fragile alpine tundra ecosystems and unique animals that, while well adapted to these harsh high-altitude peaks, are very susceptible to the impact of hikers. For the past 25 years, the Colorado Fourteeners Initiative has been the primary nonprofit partner of the Forest Service and Bureau of Land Management, building summit hiking trails, restoring damaged alpine terrain, and monitoring hiking use levels and trail conditions, as well as educating hikers about safe and responsible recreational use in these fragile areas. Our audience will achieve a better understanding of why these peaks are so sought-after by hikers and climbers, as well as the complicated balancing of interests between protecting their natural resources and providing recreational opportunities.

The End of Time
With the earth rapidly warming, the oceans rising, disasters spreading, and species after species hurtling towards extinction, it can be hard not to worry that we may be approaching the end of something: of society as we know it and even of time itself. But what would it mean for time to end? What is time anyway? And why do we experience it the way we do? What does it say about us as a society that we have come to understand it as a more or less straight line, infinitely divisible, angled always upwards? Could it be related to the crises that we are facing? Ben Ehrenreich will discuss these questions and his latest book, Desert Notebooks: A Roadmap for the End of Time (2020), which “layers climate science, mythologies, nature writing, and personal experiences into a stunning reckoning with our current moment and with the literal and figurative end of time.”

The Epic (and Operatic) Tale of the Rocky Mountain Locust: An Environmental Murder Mystery featuring Locust: The Opera
The story of the Rocky Mountain locust, which blackened the skies of North America for centuries and formed a swarm covering nearly 200,000 square miles in 1875, was ripe for transformation into a commensurately grand form. Perhaps even more remarkable than the breathtaking scale of its outbreaks was its sudden disappearance, with the last living specimen being collected in 1902.

Dr. Michael Edwards
June 20, 2019- Understanding your DNA: The Past, Present and Future of Human Genetic Research
Information contained in the ~6 billion bits of code stored in our DNA can be used to trace ancestry across the planet, to convict someone of murder, or to predict the potential for a terminal disease in later life. The cost of determining this genetic code for the average person has previously been prohibitive, but recent scientific advances have now made it feasible for many U.S. citizens to know their genetic makeup.
Dr. Edwards is the founder of the bioinformatics consulting company, Bioinfo Solutions LLC. He is active in teaching science and math at all levels, from instructing high school students in ‘big data’ analysis to holding workshops for clinical oncologists interested in using genomics in their cancer research. This lecture will attempt to summarize the current state of genetic research and to explain how all this information will completely change the way we do science and medicine in the future.

Dr. William Anderegg
August 1, 2019- Hot, Dry, and Smoky: What is the future of Colorado’s Forests in a Changing Climate?
The fate of the forests of the western United States in the twenty-first century with rapid human-caused climate change is largely unknown. In the past twenty years or so, climate change-supercharged fires, droughts, and beetle outbreaks have prompted concern that forests might die off en masse across the West. Dr. Anderegg, assistant professor of biology at the University of Utah, grew up in Cortez, Colorado, and still spends his time hiking, backpacking, hunting, and fishing across the Colorado Rockies. His research centers on the intersection of ecosystems and climate change, especially the future of Earth’s forests in a changing climate. He has studied western forests for more than a decade and his investigation seeks to shed light on the future of Colorado’s forests. The aim of his research is to develop predictive tools to help forecast and manage the fate of western forests in this century.
