November 2024 Program
What: Insiders look at the new edition of the Cherokee National Forest Hiking Guide by Will Skelton, Richard Harris, James Wedekind, and Hiram Rogers
When: Tuesday, November 12, 2024, 7:00-8:30 PM
Where: Tennessee Valley Unitarian Universalist Church 2931 Kingston Pike, Knoxville TN.
The third edition of the only hiking guidebook to all of the trails in the Cherokee National Forest, the Cherokee National Forest Hiking Guide, was recently published by UT Press. It covers 840 miles of trails (plus the Benton MacKaye Trail’s 99 miles) and 225 trails in the 555,598 acres National Forest (all more than in the Smokies). The National Forest is filled with wonderfully scenic mountains, creeks, forests, wildlife, wildflowers, and grassy balds and will help the public enjoy the Forest. Our November program meeting will feature the editor of the book, Will Skelton, one of the two assistant editors, Richard Harris, and two of the 39 people who worked on the book, James Wedekind and Hiram Rogers, talking about how they got the book done and showing photos from the book. Doing the book required countless hours of work and well over a year to complete, with people hiking all of the trail miles with GPS devices for mileage and directions and then writing up the various trails for the book. The book also has a wealth of additional information including how to advice, the history of how the National Forest’s protected areas came to be, maps and GPS use, and lots more. There are maps of all the trails in the book and also photographs that were taken of most of the areas and assembled by Roger Jenkins. The result was an outstanding and comprehensive guide to the Cherokee National Forest’s natural wonders.

What: Native Fish Restoration in the Great Smoky Mountains National Park by Caleb Abramson, Fisheries Technician, Great Smoky Mountains National Park
When: Tuesday, May 9, 2023, 7:00-8:30 PM
Where: Tennessee Valley Unitarian Universalist Church 2931 Kingston Pike, Knoxville TN
Great Smoky Mountains National Park contains nearly 2,900-miles of perennial waterways ranging from high-elevation creeks to lower elevation rivers. Approximately 700 of those miles are occupied by almost 70 species of fish from 12 different families, including: lampreys, darters, shiners, minnows, suckers, bass and trout. Brook Trout, the only native salmonid species in the Smokies, lost more than 75-percent of its original range due to wholescale logging prior to the National Park’s establishment. Those populations that did survive were relegated to the highest elevation streams that saw little timber harvest. Unfortunately, the areas those fish persist also receive higher loads of atmospheric deposition, which lowers stream pH. Fishery managers have been working to restore native Brook Trout to select mid-elevation watersheds with more stable stream chemistry. To date, managers have restored more than 31-miles of select streams to purely Brook Trout. Restoration efforts continue to be performed.

What: Measurements and Models: The Science of Climate Change by Dr. Peter Thornton, Director of the ORNL Climate Change Science institute
When: Tuesday, October 10, 2023, 7:00-8:30 PM
Where: Tennessee Valley Unitarian Universalist Church 2931 Kingston Pike, Knoxville TN.
Earth’s climate is changing faster today than at any time in recorded history, and human influence on the atmosphere through fossil fuel combustion and other sources of greenhouse gas emissions is known to be the primary factor driving this change. Atmospheric concentration of carbon dioxide is higher than any time in the previous million years and is rising steadily. The impact of these changes is seen on every continent with global and regional warming trends that are unambiguous since at least the 1980s.
In this presentation we will examine at the observations underlying our understanding of these Earth system changes, and we will explore how we know what causes the observed changes. We will also look at what computer models can tell us about future climate changes, and the uncertainties around those predictions. We will assess the impacts of climate change and discuss options for how humanity can respond to this unfolding crisis.
About Peter Thornton: Peter studies biogeochemistry of land, coastal, and aquatic ecosystems, and incorporates that knowledge into models to improve predictions of future climate. His research spans spatial scales from plots to the global Earth system. A special focus of his research is the coupling of the biotic and abiotic cycling of nutrients such as nitrogen and phosphorus which limit growth and metabolism of plants and microbes.
Peter is the Director for ORNL’s Climate Change Science Institute, which brings together researchers from across the Lab with shared interests and expertise in climate change science, impacts, and solutions. He is also Section Head for the Earth Systems Science Section within ORNL’s Environmental Sciences Division, which integrates the efforts of empiricists, experimentalists, and modelers working at scales from sites to watersheds to the globe. Peter has been recognized multiple times by Clarivate’s Web of Science as a Highly Cited Researcher. He is a Fellow of the American Association for the Advancement of Science.
Peter is a mentor to several technology projects within the Oak Ridge Public Schools and serves as a board member for the Oak Ridge Public Schools Education Foundation. He enjoys running, hiking, and making music. Contact: thorntonpe@ornl.gov

When: Tuesday, November 14, 2023, 7:00-8:30 PM
Where: Tennessee Valley Unitarian Universalist Church 2931 Kingston Pike, Knoxville TN.
For wildlife whose ancestors have traversed our landscapes for centuries in search of food, mates, and territory, this is not the question. Their instinct is to continue moving across age-old geographical paths.
Since 2017, more than 20 regional organizations have been collaborating to make Interstate 40 between Asheville and Knoxville safer for people and wildlife. This partnership ultimately led to the creation of Safe Passage: The I-40 Pigeon River Gorge Wildlife Crossing Project.
This presentation will explore what this coalition is doing to prevent wildlife-vehicle collisions in this vital wildlife corridor. You’ll learn what the project is, why it's important, what’s a stake, who’s involved, what activities are currently underway to provide safe passage for wildlife across this major highway that bisects the Great Smoky Mountains National Park and Pisgah National Forest, and how you can help.
Tracy Davids is the Outreach Committee Chair for the Safe Passage Fund Coalition comprised of The Conservation Fund, Defenders of Wildlife, Great Smoky Mountains Association, National Parks Conservation Association, North Carolina Wildlife Federation, Wildlands Network and The Wilderness Society — all of which are dedicated to making the 28-mile section of Interstate 40 in the Pigeon River Gorge a safer place for wildlife and humans alike. They are supported by a stakeholder group of nearly 20 federal, state, tribal, and non-governmental organizations. More information on the coalition can be found at smokiessafepassage.org

What: The Value of Trees for Sustainable Urban Water: Interest in an Old Friend by Dr. Jon Hathaway, Associate Professor, UTK
When: Tuesday, February 13, 2023, 7:00-8:30 PM
Where: Tennessee Valley Unitarian Universalist Church 2931 Kingston Pike, Knoxville TN.
Urbanization causes fundamental shifts in the landscape’s water balance, leading to unintended consequences such as flooding and water quality degradation. For nearly a decade, Dr. Hathaway’s research team at the University of Tennessee has worked to understand the role of trees for mitigating these effects. From tree contributions to rain gardens, to rainfall interception, its clear trees have significant value in urban spaces. In this presentation, Jon will provide a synopsis of what we’ve learned, and discuss his next project that will bring a substantial number of tree-centric stormwater treatment practices to East Knoxville over the next five years.
About Jon Hathaway: Hathaway received his PhD from North Carolina State University in 2010, where he studied the fate, transport, and removal of indicator bacteria in urban stormwater runoff.

What: Why Trust Models? The Process of Building Confidence in Projections of Climate Impacts
When: Tuesday March 12, 2024, 7:00-8:30 PM
Where: Tennessee Valley Unitarian Universalist Church 2931 Kingston Pike, Knoxville TN.
Prediction is difficult, especially if it’s about the future. For scientists working to understand consequences of a rapidly changing climate, that famous quote is not just a humorous quip, but a workaday challenge. As we grapple with the consequences of a changing climate for water resources, built infrastructure, and the environment, complex computer models are indispensable tools. Models used for projections of climate impacts are system-level models that combine representations of surface water, soil water, surface vegetation, and groundwater dynamics. In this presentation, we will explore how scientists build confidence in those integrated hydrologic models as tools for understanding climate impacts. Using ORNL work to understand how a warming climate will likely affect Arctic tundra landscapes as an example, we will explore how multiple lines of evidence are used to improve confidence in model projections.
About Scott Painter: Scott is a computational hydrologist and leader of the Watershed Systems Modeling Group at ORNL. His research focuses on improving predictive understanding of how water, waterborne material, and heat move through natural and human impacted environments and the implications of those flow and transport processes for society and ecosystem health. He and his team build state-of-the-art simulation tools, compare model results to laboratory experiments and field observations, and perform numerical experiments to understand implications of climate change on water resources and ecosystems. Prior to joining ORNL, Scott had research positions at Los Alamos National Laboratory, Southwest Research Institute, and CSIRO-Australia. Contact: paintersl@ornl.gov

What: Collaborations for Conservation by Nancy Manning, Executive Director TCWP
When: Tuesday, May 14, 2024, 7:00-8:30 PM
Where: Tennessee Valley Unitarian Universalist Church 2931 Kingston Pike, Knoxville TN.
The Tennessee Citizens for Wilderness Planning (TCWP) and the Harvey Broome Group of the Sierra Club share a rich history dating back to the founding of both organizations. Throughout the years, we have collectively identified environmental threats and mobilized the strength, resilience, and commitment of our members to address them. Despite numerous successes, we have never allowed ourselves to rest on our laurels. Even as we've secured protection for threatened areas, new challenges have emerged, sometimes within those very areas we fought to safeguard. Today, the stakes are higher than ever in our organizations' histories, as we confront unexpected failures within the legal system.
In this presentation, Nancy will discuss the historical and ongoing successes of TCWP, the enduring inspiration that propels us forward in the face of persistent threats, and a proposal for immediate collaboration in conservation efforts. Drawing upon the Native American principle of "Calling the Circle," Nancy will present a compelling case for united action in preserving our natural heritage.
Nancy Manning, JD, current Executive Director of Tennessee Citizens for Wilderness Planning, is an attorney, certified mediator, trainer, manager, facilitator and consultant. Nancy owned the Law Office of Nancy Manning for 25 years, with a primary focus of serving indigent Native Americans in Rapid City, South Dakota. Nancy served on 3 nonprofit boards in Rapid City, including Lifeways, the Restorative Justice Center and the Pennington County Air Quality Control Board. She created the first mediation practice and training center in Rapid City and was the only service provider there for 15 years. Nancy moved to Texas in 2007 and became Executive Director of a conservation nonprofit, where she helped to raise more money in 7 years than had been raised in the prior 52 years. As the Executive Director she led efforts to develop, plan & implement a 7-year outreach initiative to engage an ethnically diverse community in conserving a 10-acre habitat on the east side of Austin which engaged local youth in outdoor education. Nancy was recognized for Innovative Environmental Leadership; one of 40 individuals nationwide selected as a 2011 Audubon / Toyota TogetherGreen Fellow to further this east Austin conservation outreach effort, which engaged over 1200 volunteers. Nancy founded her consulting company, Power Your Mission, in 2014 and founded Austin Nonprofit Meetup in 2018 where she provided online monthly meetups for nonprofit leaders nationwide until 2022. She is currently the Executive Director of Tennessee Citizens for Wilderness Planning.

What: Cryptocurriencies and Climate Change Casualties by John Nolt, Professor Emeritus, University of Tennessee
When: Tuesday, June 11, 2024, 7:00-8:30 PM
Where: Tennessee Valley Unitarian Universalist Church 2931 Kingston Pike, Knoxville TN.
There’s a lot not to like about cryptocurrencies. For one thing, they make it easy to conceal financial crimes. But they also have detrimental long-term effects on the environment. Cryptocurrency “mines” (data centers, really) pull enormous quantities of power from the electrical grid. Thus they are attracted to states like Tennessee where electric power is relatively cheap. This forces TVA and other utilities to plan new fossil-fueled power plants or extend the lifetimes of old ones to meet the demand. If these plans are carried through, we will blow through greenhouse gas emissions targets and global heating will intensify dangerously. The predictable result is increased human casualties (injuries, illnesses, displacements, and deaths) and rapidly accelerated degradation of nature. This talk traces the causal links that lead to such tragedies and suggests ways to break them.

What: A Rational Basis for Hope: Human Behavior Modeling and Climate Change by Dr. Louis J. Gross, Chancellor's Professor Emeritus of Ecology and Mathematics, University of Tennessee
When: Tuesday, August 13, 2024, 7:00-8:30 PM
Where: Tennessee Valley Unitarian Universalist Church 2931 Kingston Pike, Knoxville TN
It is easy to lose confidence in the capacity for human social and political systems to respond effectively to the challenges from rising average global temperature and associated climate change. A working group of diverse researchers with backgrounds in mathematical modeling, climate science, psychology, sociology, economics, geography and ecology has addressed the question as to whether there is any rational basis to expect that human behavioral changes can sufficiently impact climate to significantly reduce future mean global temperatures. Climate models can readily make assumptions about reductions in future greenhouse gas emissions and project the implications, but they do this without accounting for feedbacks from human behavior. We have developed models to build a rational basis to link social system and human behavior with climate. Results from these efforts is that there is indeed some rational basis for hope, with social, political and technical feedback processes driving future climate policies and emissions. Under some circumstances these lead to a meaningful reduction of projected future average temperature.
