Groups to carry on air quality work, defend U.S. investments and ensure voices are heard from all communities

This story is from North Carolina News Service.

RALEIGH — President-elect Donald J. Trump retakes office in less than a week amid promises to roll back efforts to combat climate change. A friendly Congress could follow suit. But state-level efforts to address the crisis will continue in North Carolina, at least.

Trump has promised to repeal the Inflation Reduction Act passed under President Joe Biden, which earmarked billions for climate-resilience and alternative energy projects. Brittany Griffin with the nonprofit CleanAIRE NC says tinkering with the law would hurt the state, including its ability to prepare for more severe weather as climate change worsens. But she says there are still glimmers of hope on the state level.

“We still have a lot of state-led policies, and then our makeup now of the General Assembly looks different. We have a governor who also is pretty well-informed and, I believe, dedicated to addressing environmental issues in our state,” he said.

Griffin added that her organization will be working with community and legal partners to resist potentially harmful changes under the Trump administration, and ensuring that all citizens have a voice in their environment. CleanAIRE NC’s community science manager Daisha Walls is on the Environmental Justice Advisory Council for the Governor’s Office.

Griffin noted that there are a number of ways CleanAIRE NC is helping people feel more empowered, such as through its air monitoring networks in communities across the state and clean energy transportation efforts in rural areas, and said community member involvement is important to the state’s response to climate change.

“When they amplify their voice, it allows them to feel like they are participating in the process of shaping environmental policies as it relates to their communities,” she said.

North Carolina lawmakers have passed climate goals under the state’s Carbon Plan that aim to reduce Duke Energy’s carbon emissions by 70 percent by 2030 and reach carbon neutrality by 2050. But Griffin said the current plan falls short for the state’s underserved and impacted communities. However, it is renewed every two years and she hopes they have a larger say in the next iteration.

“We at CleanAIRE NC would like to make sure there’s more inclusion for all communities in the planning process so they can actually more directly benefit from it,” she said.

OAK RIDGE — Researchers at the Department of Energy’s Oak Ridge National Laboratory joined forces with EPB of Chattanooga and the University of Tennessee at Chattanooga to demonstrate the first transmission of an entangled quantum signal using multiple wavelength channels and automatic polarization stabilization over a commercial network with no downtime.

The successful trial of this innovation marks another step toward the eventual creation of a quantum internet that could prove to be more capable and secure than existing networks.

Quantum computing relies on quantum bits, or qubits, to store information. Qubits, unlike the binary bits used in classical computing, can exist in more than one state simultaneously via quantum superposition, which allows combinations of physical values to be encoded on a single object.

The demonstration used automatic polarization compensation, or APC, to stabilize the polarization, or direction of the electric field oscillation in a light wave, of a signal sent over the EPB’s fiber-optic commercial quantum network. The approach used reference signals generated by lasers to continuously check the transmitted polarization, detected with an ultrasensitive method known as heterodyne detection.

APCs reduce data interference caused by outside forces like wind and temperature changes that can affect the fiber optic cables used to transmit quantum signals.

“One of our goals all along has been to develop quantum communications systems that operate seamlessly for users,” said Joseph Chapman, an ORNL quantum research scientist who led the study. “This is the first demonstration of this method, which enabled relatively fast stabilization while preserving the quantum signals, all with 100 percent uptime — meaning the people at either end of this transmission won’t notice any interruption in the signal and don’t need to coordinate scheduled downtime.”

The method enabled continuous transmission of the signals with no interruptions for more than 30 hours between the node on the University of Tennessee Chattanooga campus and two other EPB quantum network nodes, each about half a mile away. The UTC node held an entangled-photon source developed by Muneer Alshowkan, an ORNL quantum research scientist.

Saving barrens full of life

Written by

tennessee coneflower couchville cedar gladeTennessee coneflower is seen in Couchville cedar glade, a prime example of cedar glade habitat that is a target of preservationists — such as the land acquired recently in Rutherford County by TennGreen Land Conservancy. The Couchville property is managed by the Tennessee Department of Environment and Conservation. It is similar in nature to the TennGreen property in Rutherford County, and is part of a nexus of such glades around the Cumberland Plateau. According to TDEC: “Couchville supports one of the largest known and best quality populations of the Tennessee coneflower (Echinacea tennesseensis), which was delisted as a federally endangered species in September 2011. Couchville also provides one of the finest examples of a glade-barrens complex and protects many rare plant species. The glades are distributed where limestone outcropping and shallow soils limit growth of perennial plants and support annual species like leavenworthia, sporobolus, and sedum. The barrens species, that also includes Tennessee coneflower, occur where soils increase and grasses like little bluestem and side oats grama become dominant. The glades and barrens interface forming a complex.”  Tennessee Department of Environment and Conservation

Cedar glade habitat protected in fast-growing Tennessee county

MURFREESBORO — To close out 2024, TennGreen Land Conservancy and Allen Patton protected 50 acres of globally unique cedar glade habitat in Middle Tennessee’s Rutherford County with a conservation easement.

Called Rockdale Cedar Glades and Woodlands, Patton’s land abuts TennGreen’s Lamar Cedar Glades & Woodlands Conservation Easement, increasing this connected corridor of protected land to an expansive 256 acres. Limestone cedar glades and barrens, which are incredibly diverse but under threat from development and pollution, are found on the protected properties. This additional 50-acre easement is also within the Spring Creek HUC 12 Watershed and the Stones River Upper HUC 12 Watershed, marking it as critical habitat.

(Hellbender Press has previously reported on the special nature and importance of cedar barrens, including one located in Oak Ridge, just on the cusp of the Cumberland Plateau, which is better known for its cedar glades).

bigsouthforkThe Big South Fork on the Cumberland River as seen at Leatherwood Ford in March 2020 when it recorded a record height of 39 feet. One year later, it recorded a new record height of 41 feet. The flooding destroyed four boat ramps in the area, the park service has now rebuilt them all. Big South Fork is a very popular paddling destination.  National Park Service

Big South Fork completes substantial repairs to four boat launches damaged in series of rain and windstorms

 ONEIDA —  Workers in Big South Fork National River and Recreation Area completed repairs to four popular boat launches damaged by significant generational flooding events over the past couple of years. 

Park staff dismantled and rebuilt the boat launches at Blue Heron Mine-18, Brewster Bridge, Station Camp and Peters Bridge, all of which were severely damaged during flooding in March 2021 that arose after 8 inches of rain fell in and around Big South Fork. The Big South Fork of the Cumberland River reached 41 feet at Leatherwood Ford; three days prior it was at 7 feet.

The second-highest flow of the river since rain gauges were installed in the park in 1984 occurred just a year earlier in 2020 when the river hit 39 feet.

The park also experienced flooding in 2024, during which a man perished after he fell in a park waterway. Severe storms also damaged or destroyed multiple Big South Fork facilities and blocked roads and trails for weeks.

Big South Fork includes nearly 250 miles of rivers and streams and is a destination park for water recreation, and rock climbing.

Mature Soybeans S.

Poor production, low commodity prices mean difficult times for many in state agriculture sectors

Patricia McDaniels is senior media relations coordinator and editor at the University of Tennessee Institute of Agriculture.

KNOXVILLE — In 2024, Tennessee’s agricultural and forestry industrial complex was significantly impacted by six major factors: drought, agricultural land loss, trade deficits, decreasing foreign market demand, below average yields and relatively lower prices for major commodities.

Researchers and Extension specialists from the University of Tennessee Institute of Agriculture Department of Agricultural and Resource Economics also suggest that the outlook for 2025 could vary depending on the sector.

In the annual economic report to the governor of Tennessee prepared by the Boyd Center for Business and Economic Research at the UT Haslam College of Business, the agricultural and resource economists provide an economic outlook for the state’s farmers and foresters.
 
“The state’s agricultural and forestry industries directly and indirectly contributed $103 billion to the Tennessee economy,” says Andrew Muhammad, UTIA professor of agricultural economics.
 
“2024 was a struggle for many of our producers and sectors. Next year could also be difficult, with trade policy uncertainty, low crop prices, drought- and hurricane-reduced feed supplies and high input costs.” Muhammad is a co-author of the report and holds the Blasingame Chair of Excellence in Agricultural Policy.
 
In terms of gross output, the agricultural and forestry industrial complex measured 11 percent of the economic activity conducted in Tennessee in 2024. An estimated 385,743 individuals worked in industries supported by the complex, which is 8.8 percent of the state’s total employment.
 
“Due to the dramatic declines in gross revenue in 2024, many crop producers will struggle with obtaining financing for the 2025 crop, which could affect production and result in consolidation in the row crop sector in Tennessee,” Muhammad and his co-authors write in the report. They add that negative factors affecting the livestock, poultry and dairy industries in 2025 will be continued high interest rates when financing operations and equipment, as well as inflation and reduced discretionary spending available to consumers.

Citizen-led Audubon Christmas Bird Count tallies our feathered friends for yet another year

Holly Kays is the lead writer for Smokies Life.

GATLINBURG — Since its origin in 1900, the Christmas Bird Count has become a holiday fixture for ever-expanding numbers of birders across the globe, giving a valuable gift to generations of wildlife scientists — a massive trove of data on bird populations in the Western Hemisphere.

This annual avian census, set to commence for the 125th time, began in an era when many bird species were facing steep declines, especially waterfowl prized for their feathers. The Christmas Bird Count was the National Audubon Society’s answer to the traditional Christmas Side Hunt, a team competition that encouraged participants to kill as many furred and feathered creatures as possible in a single outing.

“The Christmas Bird Count really got started as an alternative to those kinds of hunting efforts,” said Curtis Smalling, executive director of Audubon North Carolina. “This year is the 125th annual Christmas Bird Count, and that makes it the longest-running community science project in North America.”

Anyone can participate in the CBC, regardless of their birding skill level, by joining one of the thousands of circles, each 15 miles in diameter, that comprise the event. The organizer of each circle chooses a day between December 14 and January 5 to conduct their count. On the appointed day, all participants in the circle have 24 hours in which to tally as many birds as they can. In addition to listing the individual species spotted, they also count the number of individual birds seen and participant hours logged.

The Great Smoky Mountains region includes circles in Gatlinburg, Cades Cove, Knoxville, Franklin, Highlands, Waynesville, Hot Springs and Asheville.

If you have birdfeeders at home, remove any dead birds you may encounter and stop feeding; minimize any poultry/wildlife interactions

Lee Wilmot is a TWRA information specialist. This story will be updated. 

NASHVILLE — The Tennessee Wildlife Resources Agency is reminding hunters to remain vigilant and take appropriate precautions as reported cases of Highly Pathogenic Avian Influenza (HPAI) increase among wild birds, backyard domestic flocks and commercial poultry flocks in the Southeast.  HPAI is highly contagious among bird populations and is known to be deadly for domestic fowl.

(California Gov. Gavin Newsom on Dec. 18 declared a state of emergency in California as cases in that state jump dramatically).

“Numerous states in the Mississippi Flyway are reporting HPAI detections that are leading to dead and dying birds, mainly snow geese,” said Jamie Feddersen, TWRA Migratory Gamebird Coordinator. “Tennessee is also finding ducks and geese with HPAI. Hunters should follow safety precautions when handling these birds.”

“Since March 2022, Tennessee has confirmed numerous cases of Highly Pathogenic Avian Influenza in wild birds, including ducks, Canada geese, vultures and a Bald Eagle,” said TWRA Wildlife and Forestry Chief Joe Benedict. “We urge homeowners and hunters to take precautions to prevent the spread of the disease in Tennessee and to protect wildlife and poultry populations.”

USFWS seeks public comment on proposed listing of crucial indicator species throughout its known range; several populations in Smokies region

Melissa Clark is a U.S. Fish and Wildlife Service senior public affairs specialist.

The U.S. Fish and Wildlife Service announced Dec. 12 a proposal to list the eastern hellbender as an endangered species throughout its range under the Endangered Species Act. Eastern hellbenders are found in Alabama, Georgia, Illinois, Indiana, Kentucky, Maryland, Mississippi, Missouri, New York, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia and West Virginia.

“The eastern hellbender is a unique salamander that plays a crucial role in maintaining healthy freshwater ecosystems,” said Service Midwest Regional Director Will Meeks. “As key indicators of stream and river health, hellbenders need protection that also will help support healthier ecosystems across their range.”

Historically, eastern hellbenders have been documented in 626 populations. Recent data indicate only 371 of these populations (59%) remain. Among the remaining populations, only 45 (12%) are stable, 108 (29%) have an unknown recruitment status, and 218 (59%) are in decline.

The eastern hellbender is one of two subspecies of hellbenders in the United States. The other subspecies, the Ozark hellbender, occurs in Missouri and Arkansas and was listed as an endangered species in 2011. In 2021, the Missouri distinct population segment of the eastern hellbender was listed as endangered.

— Nikki Giovanni

This story was originally published by Tennessee Lookout. 

BLACKSBURG — Knoxville native Nikki Giovanni, a poet, civil rights legend and educator who empowered generations with her fearless words and unwavering advocacy for Black America, died on Dec. 9 at the age of 81 after her third cancer diagnosis.

“The acclaimed poet, Black Arts Movement icon whose poems of wit, wonder and wisdom were celebrated in children’s books, on keynote stages and television shows, and in more than two dozen bestselling poetry collections, died peacefully on December 9, 2024, with her life-long partner, Virginia [Ginney] Fowler, by her side,” said friend and  author Renee Watson in a statement. 

In 2023, Knoxville’s Beck Cultural Exchange Center unveiled an exhibit dedicated to Giovanni, featuring her complete book collection and personal memorabilia. The center, a cherished space for Giovanni, was a must-visit whenever she returned to her hometown.

“Nikki was a gift to the world, generously sharing her talents with everyone around her,” said Rev. Reneé Kesler, President of the Beck Cultural Exchange Center. She loved deeply and expressed that love in countless ways.”

Yolande Cornelia “Nikki” Giovanni was born on June 7, 1943, in the “Negro Wing” of Knoxville General Hospital to parents Yolande Cornelia Sr. and Jones “Gus” Giovanni. She graduated from Austin High School in 1961.

She enrolled at the historically Black Fisk University in Nashville in 1960. At Fisk, she joined the Writer’s Workshop, a space that fostered her creativity and connected her with other aspiring Black writers who later went on to become prominent Black literary figures such as Dudley Randall, Margaret Walker and Amiri Baraka. 

“At Fisk, she found her voice — a voice that would go on to inspire the world to dream with courage, to fight with purpose and to love without constraint. Through her poetry, she wove stories of Black resilience, beauty and liberation. Her spirit is forever etched into the soul at Fisk, an eternal light guiding us toward justice, creativity and authenticity,” Fisk officials said in a statement.

Conservation groups have cautioned against the zombie roadway between Wears Valley and Gatlinburg; EIS-level study uncertain

This story will be updated.

The National Park Service (NPS) said Dec. 9 it “will conduct additional design work and technical studies for Foothills Parkway Section 8D. This decision was based on feedback from subject matter experts and public comments received during a 30-day public comment period that ended Aug. 21.
“The NPS will reinitiate the National Environmental Policy Act (NEPA) process and inform the public of opportunities for future public engagement once this additional work is completed. A schedule for completing the additional work has not yet been established,” according to a release from NPS public affairs specialist Dave Barak.
 
Conservation groups, including the National Parks Conservation Association, say the road would further fragment forest habitat and present unacceptable water-quality hazards.
 
The NEPA offers a range of alternatives, however, and it was not immediately known whether the park service would again embark on a more detailed environmental impact statement (EIS) or proceed with a relatively cursory environmental assessment.
 
A draft of the previous EIS process for this parkway project were completed decades ago, as reported by Hellbender Press.
 
The federal government last year opened the latest round of public comment on the project, which would traverse Buckeye Knob and Cove Mountain and multiple aquatic and karst environments.

 

Concerns raised by the public over the decades range from impacts on domestic water supplies and endangered or threatened species to the fact the roadway might be a catalyst for excessive tourism infrastructure in Townsend and Wears Valley.

NOAA’s Teek and Tom bring fun and free science to classrooms and homes

Screen Shot 2024 12 03 at 1.44.28 PM

It’s all about the ocean-weather-climate connection!

Join intrepid student explorer Teek from planet Queloz and National Oceanic and Atmospheric Administration (NOAA) climate scientist Tom Di Liberto as they explore planet Earth’s weather and climate. This five-part science series covers a range of scientific topics, including how the ocean influences weather and climate on Earth, and the technologies scientists use to gather information about our planet and its changing climate.

Each episode is supplemented by two lesson plans designed for students in the fourth through sixth grades — all of which are compiled in a single Educator’s Guide. Each lesson allows students to explore and investigate NOAA data, visualizations and content, allowing them to build knowledge of and skills associated with important Earth science concepts.

An understanding of how the Earth works as a system and how humans interact with the Earth is important for all inhabitants of our planet. Teek and Tom are a fun and engaging way to grow that understanding!

Teek and Tom: Educator’s Guide

The Teek and Tom Educator’s Guide includes 10 lesson plans — two supplementing each episode. The lessons allow students to build knowledge of and skills associated with important Earth science concepts. Through the exploration and investigation of NOAA data, visualizations, and content, the lessons support the videos in telling a cohesive story of key Earth systems, and how those systems impact each other.

Each lesson is aligned to the Next Generation Science Standards (NGSS), national standards for mathnational standards for English and language arts, and the College, Career, and Civic Life (C3) Framework for Social Studies State Standards. These standards reinforce the interdisciplinary nature of ocean, weather and climate studies, and support the teaching of these topics. The lessons engage students in content that is locally relevant; and use the 5E model (Engage, Explore, Explain, Elaborate, Evaluate) to provide a structure for students to connect science ideas with their own experiences, and apply their learning to new contexts.

ORNL central to East Tennessee nuclear resurgence

Written by

kairosornlOak Ridge National Laboratory

Demonstration reactor projects, alternative fuel among projects centered around Oak Ridge, an old-school nuclear town

Leo Williams is the editor of ORNL Review. UT-Battelle manages Oak Ridge National Laboratory for the Department of Energy’s Office of Science. The full interactive article is available here.

Offer your perspective on this article and the new rise of nuclear technology in East Tennessee by contacting Hellbender Press Editor Thomas Fraser at This email address is being protected from spambots. You need JavaScript enabled to view it..

OAK RIDGE — In fall 2020, California-based Kairos Power announced plans to build an advanced nuclear demonstration reactor within the site of the former K-25 uranium enrichment plant in Oak Ridge.

It was a good location for the company. The decommissioned K-25, now named Heritage Center Industrial Park, came with impressive infrastructure, including ample electricity from the Tennessee Valley Authority, abundant water from the nearby Clinch River and more than 11 miles of rail line connected directly to the Norfolk Southern system. Interstate 40 was less than five miles away.

Perhaps more importantly, the location gave Kairos’ scientists and engineers close access to an unmatched pool of nuclear expertise. ORNL, which helped start the nuclear age more than 80 years ago and remains at the forefront of nuclear research, is all of five miles away. The University of Tennessee, Knoxville, which hosts a prestigious nuclear engineering department dating back to 1957, is just 30 miles down the road.

And the federally owned TVA, which has operated nuclear power plants since 1974, is developing its own next-generation nuclear reactor about three miles away.

In particular, though, the company wanted to be near a national lab, according to its co-founder Mike Laufer.

“The big decision for us was where we were going to put the Hermes reactor,” he said.

“For that, we pretty quickly narrowed down that we had a strong preference to be in close proximity to a national laboratory, with capabilities that could augment our own infrastructure.”

Hermes will be a 35-megawatt molten salt-cooled reactor that uses a new kind of uranium fuel called TRISO — short for tristructural isotropic particle fuel. The billiard ball-sized TRISO pebbles will consist of uranium, carbon and oxygen particles surrounded by carbon- and ceramic-based materials designed to prevent the release of radioactive fission products. The reactor will not produce electricity; rather, it will demonstrate the company’s technology before Kairos moves on to building much larger commercial reactors.
