The TN Lunabotics, science and sustainability get together at BOSS event
KNOXVILLE — What do environmental, social and economic sustainability have in common?
There are numerous ways to answer that question, but for those who pay close attention to education or economics it’s an accepted fact that the future belongs to societies that invest heavily in STEM (Science, Technology, Engineering and Mathematics).
That’s why educators at all levels are pushing students towards those subjects at every opportunity, as was evidenced Jan. 21 at Big Orange STEM Saturday (BOSS) at the University of Tennessee.
About 150 high school students picked from communities across East Tennessee spent much of their Saturday at John C. Hodges Library, getting a first-hand taste of what awaits them should they choose to pursue careers in STEM through the UT system.
Each year more than 600,000 people visit Ijams Nature Center
This is the second installment of an occasional series, Hellbent, profiling citizens who work to preserve and improve the Southern Appalachian environment.
KNOXVILLE — On any given day, the parking lot at Ijams Nature Center in South Knoxville is packed with cars, trucks, and buses as folks of all ages flock to hike, climb, swim and paddle its 300-plus acres of protected wildlands.
Making sure the center’s 620,000 or so annual visitors have a positive experience interacting with Mother Nature requires dozens of full-time employees plus a generous contingent of volunteers. Ensuring the complex operation stays on course and within its $1.8 million operating budget is a tough job, but Ijams Executive Director Amber Parker has been doing it for six years now and has no desire to be doing anything else.
When Amber talks about Ijams she fairly bursts with giddy, infectious energy. This is a woman who has clearly found her place in the world, and even a brief walk along any of the center’s 21 trails makes one wonder if the land itself hasn’t responded in like fashion to her devotion.
The crucial Amazon rainforest is nearing a point of no return
The Amazon has long served as a vast carbon sink, even as vegetation pumped oxygen into the atmosphere to the point it was called the “lungs of the Earth.”
But vast deforestation, despite calls to save the Amazon that originated decades ago, portends profound changes in the ecology of the huge, increasingly fragmented forest that lies mainly within Brazil.
“Just in the past half-century, 17 percent of the Amazon — an area larger than Texas — has been converted to croplands or cattle pasture. Less forest means less recycled rain, less vapor to cool the air, less of a canopy to shield against sunlight,” according to a report from Alex Cuadros.
“In one study, a team led by the researcher Paulo Brando intentionally set a series of fires in swaths of forest abutted by an inactive soy plantation. After a second burn, coincidentally during a drought year, one plot lost nearly a third of its canopy cover, and African grasses — imported species commonly used in cattle pasture — moved in.”
Updated 1/3: Conservationists express dismay as Feds conclude ‘no significant impact’ from construction of Wears Valley mountain bike complexWritten by JJ Stambaugh
Feds clear 14-mile mountain bike trail network off Foothills Parkway, but no funding is secured
GATLINBURG — Those who logged protests against a National Park Service plan to carve a 14-mile mountain bike trail network through the forest off Foothills Parkway said they still opposed the plan despite federal conclusions it would not adversely impact the natural environment of the area.
“I’m very disappointed,” said Donna Edwards, an outspoken conservationist who lives in Walland and participated in the public scoping process. “What are (the) reasons for choosing the alternative with the largest footprint and greatest environmental impact?
“I fail to understand why mountain bikers’ needs are considered to be more important than those of birders and hikers, considering the extensive mountain bike trail networks in other areas of East Tennessee.”
She said arguments against approving the Wears Valley mountain bike trails were wise and well documented.
Here is the original Hellbender Press story:
A proposed off-road bike trail in the Wears Valley section of the Foothills Parkway that would be operated by the National Park Service has overcome a procedural hurdle but appears to be no closer to actually being built due to a lack of funding.
An environmental assessment to determine the project’s potential impact on wildlife and the environment led to an official “Finding of No Significant Impact” (FONSI), park officials said in a press release issued Thursday.
“We understand the public’s desire to have a purpose-built bike trail, and this marks a step for potential future development of a trail in Wears Valley,” said Cassius Cash, superintendent of the Great Smoky Mountains National Park. “Having the signed FONSI allows us the opportunity to explore potential funding paths for both the construction and the annual operational costs.”

Updated 12/27: Temperatures climb and snow melts as bitter cold finally moves out of Southern AppalachiansWritten by JJ Stambaugh
Southern cities emerge from frigid airmass after Christmas weekend of brutal cold and snow
KNOXVILLE — Temperatures rose above freezing on Tuesday for the first time since Dec. 23 following a weekend bout with historic cold, high winds, burst water and sewage lines and power outages. The chaos was punctuated with unexpectedly potent snowfall Dec. 26 on frigid roadways that snarled traffic in the city and metro area.
The snow came in the wake of a brutal cold front that first moved into the region in the early hours Friday morning.
Snow didn’t start falling until Monday afternoon, and by sunrise Tuesday between .5 and 2 inches of the white stuff had blanketed the area, falling upon already frigid roadways.
Public safety officials across the region urged motorists to stay home, and numerous government offices either closed or got off to a late start Tuesday due to icy roads.
Both the Knoxville Police Department and Knox County Sheriff’s Office activated their Severe Weather plans, which meant that officers would only respond to emergencies and wrecks with injuries.
Crews from the city used brine and rock salt to treat streets designated as Level I (main thoroughfares like Kingston Pike and Broadway) and Level II (connector roads like Sutherland Avenue and Martin Luther King Jr. Boulevard).
In Great Smoky Mountains National Park, where more than 4 inches of snow fell, officials closed several roads, including the Gatlinburg Bypass, Foothills Parkway West, Laurel Creek Road at the Townsend Wye, and Little River Road from the Sugarlands Visitors Center to the Townsend Wye.
Among the lower elevations in the East Tennessee Valley, Blount County had the most snow with 2 inches on the ground; most of Knox County registered 1.5 inches, according to meteorologist Allan Diegan of the National Weather Service office in Morristown.
While the snow brought its own share of problems and excitement, many people were still recovering from a bitter cold front that swept through the region over the Christmas weekend.
While some native East Tennesseans can remember even colder storms, the type of single-digit temperatures seen from Dec. 23 to 25 came as a surprise to many residents, according to Diegan.
“I wouldn’t say this was rare by any means, but it normally doesn’t happen in December,” Diegan said. “Our coldest days are usually in January and February. This just hasn’t happened in several years, so for people who are just now moving here it might be a little different than what they expected.”
At Knoxville’s McGhee-Tyson airport, the mercury fell as low as 4 degrees early Friday morning, which was the lowest reading on a Dec. 23 since 1988, he said.
But that was by no means the coldest temperature ever recorded in the Knox County area, stressed Diegan — that record was set on January 21, 1985, when the mercury dropped to a bone-chilling 24 degrees below zero.
“I don’t think we saw any daily low records broken this weekend, which is kind of hard to believe,” he said. “This was, at least, the coldest it’s gotten since 2015.”
On February 20, 2015, the low in Knoxville was 3 degrees, records show.
One record that was set in Knoxville over the weekend was for the lowest recorded high temperature for December 23, said Diegan. The high on Friday never climbed above 22, which broke the record of 24 set in 1989.
The blast of cold Arctic air that wreaked havoc over much of the nation last week was so intense it managed to bring single-digit lows even though there wasn’t any snow on the ground until the cold front had already blown through.
“Typically, it takes us having snow on the ground that’s followed by a clear night for the temperatures to drop so low,” he explained. “Cloud cover acts like a blanket and solar radiation is trapped. When it clears, the solar radiation escapes and the temperatures tend to plummet.”
So what was the coldest spot in East Tennessee over the past few days and who got the most snowfall?
Unsurprisingly, Diegan said the answer to both questions was Mt. LeConte in the Great Smoky Mountains National Park.
Weather equipment installed on the 6,593-foot-tall mountain went as low as 22 degrees below zero on Christmas Eve and, after Monday’s snow storm, approximately 4.5 inches of precipitation was on the ground.

UPDATED Dec. 23: Rolling blackouts, icy spots and subzero wind chills are only some of the challenges facing hundreds of thousands of people across East Tennessee and the Southern Appalachians as a Siberian cold front barrels through the region.
In Knox County, up to 26,000 KUB customers had lost power at one time due to a combination of wind damage and a massive surge in demand for electricity. High temperatures in the Knoxville area hovered near 10 degrees throughout Dec. 23.
If your power went out for up to an hour today, in a home or commercial establishment it was likely due to rolling blackouts imposed on local utilities by the Tennessee Valley Authority.
“TVA is requiring KUB to reduce power load due to extreme demand on the electric system,” Knoxville Utility Board said in a press release.
“KUB customers are likely to experience temporary outages until TVA provides more information,” according to a statement released in the early afternoon of Dec. 23 by officials at the utility. “KUB is striving to keep rolling outages to 15 minutes and is rotating outages across the service area until TVA lifts the requirement.”
The planned outages were stopped around 1:30 p.m. but around 7,200 customers remained without power due to the high winds at that time, KUB’s website said.
The cold front — which has wreacked havoc and shattered records across much of the continental United States — roared into the Tennessee Valley in the early morning hours Friday, driving temperatures down into the single digits as winds gusted up to 40 mph.
The lowest recorded temperature in Knox County was 3 degrees in Karns; the low in downtown Knoxville stood at 7 degrees, said meteorologist Allan Diegan.
The real danger came from the wind chill, which was estimated at 5-10 degrees below zero in the early morning hours, he said. The good news was the roads were mostly clear, with few areas in the Tennessee Valley seeing more than a dusting of snow.
The mercury isn’t expected to climb above freezing until Monday, although the winds should begin to diminish on Saturday.
The rolling blackouts triggered confusion and no small amount of swearing in Fountain City during the noontime “lunch rush.” Power went out along Broadway just before 12 p.m., forcing surprised store clerks and restaurant managers to ask their customers to leave until the situation could sort itself out.
“I can’t believe I drove down here for this,” said 44-year-old Debra Wells of Halls as she walked back to her car in the Kroger parking lot. “I was going to get lunch at the deli but now it looks like I can’t even go to Chik-Fil-A (across the street).”
One manager at Kroger shook his head apologetically when asked when the store would reopen. “No idea,” he said as he locked the front doors.
The grocery store reopened within the hour, however — just as power was cut to thousands of customers in the residential areas of the Fountain City and Inskip neighborhoods for about 20 minutes.
One of the biggest concerns this weekend has been the safety of the hundreds of men, women and children who live on Knoxville’s streets, according to officials from Knox Area Rescue Ministries (KARM).
A white flag has been flying outside KARM’s emergency shelter for the homeless on North Broadway, signaling that normal rules restricting who can stay there have been temporarily waived.
“People have been streaming in all day long,” said KARM spokesperson Karen Bowdle. “There are probably close to 450 people in the building. There so many people that they’ve separated the men into the chapel and the women into the dining room.”
Karen said that KARM crews had even been taking meals and coffee to the City’s warming station across the street.
“We’re very grateful, and we’re all trying to work as a team,” she said. “There are a lot of people who will die across our country this weekend.”
The original Hellbender Press article continues below:
A historically brutal cold front expected to move into East Tennessee late Thursday has people across Knox County and beyond bracing for a potentially deadly drop in temperatures.
The approaching storm is expected to shatter low-temperature records as the temperature drops as low as 7 degrees Dec. 24, the coldest temperature ever reported in Knoxville on Christmas Eve, according to officials from the National Weather Service station in Morristown.
“The biggest concern is the wind chill,” said NWS meteorologist Kyle Snowdin, who said that daytime highs on Friday are expected to hover in the mid-teens. “There will be wind gusts of 30 to 40 mph, which means we could see temperatures of negative single digits or even negative double digits.”
City cultivation of urban nature amenities proceeds apace
KNOXVILLE — The latest phase in a multimillion dollar plan to turn the southern end of the James White Parkway into an integral part of the city’s Urban Wilderness officially kicked off Monday afternoon (Dec. 19).
Numerous officials, including Mayor Indya Kincannon, showed up for the groundbreaking of the Baker Creek Pavilion, a key component of the ambitious project.
The city is pouring $2.7 million into the Baker Creek area of the Urban Wilderness Gateway Park, which will offer public restrooms, a picnic area and plenty of parking.
Updated: Smokies crews recover drowned Knoxville kayaker
TOWNSEND — Smokies recovery teams on Monday found the body of Carl Keaney, 61, of Knoxville, in the Little River.
Keaney was last seen kayaking the Sinks during high flow when he vanished under water, prompting calls to Great Smoky Mountains National Park rangers who, along with other local crews, proceeded to search for his body for three days.
Here’s the previous Hellbender Press report:
Teams are searching for a missing kayaker in what Great Smoky Mountains National Park officials are now calling a “recovery operation” after a 61-year-old man disappeared underwater while boating above the Sinks on Little River. High water levels from recent heavy rains are making search and recovery difficult.
“Around 3:40 p.m. on Friday, Dec. 16 Great Smoky Mountains National Park dispatch received a call that a 61-year-old man had disappeared underwater while kayaking above The Sinks and did not resurface,” according to a news release from the park.
“Park rangers, along with emergency personnel from Townsend Fire Department and Blount Special Operations Response Team are on scene searching for the kayaker. High water level from recent rain is complicating recovery efforts. Little River Road from Metcalf Bottoms to the Townsend Wye is closed to accommodate emergency traffic.”

Global population growth promises a drastic spike in public health emergencies
This story was originally published by The Conversation. Maureen Lichtveld is dean of the School of Public Health at the University of Pittsburgh.
There are questions that worry me profoundly as an environmental health and population scientist.
Will we have enough food for a growing global population? How will we take care of more people in the next pandemic? What will heat do to millions with hypertension? Will countries wage water wars because of increasing droughts?
These risks all have three things in common: health, climate change and a growing population that the United Nations determined passed 8 billion people in November 2022, which is double the population of just 48 years ago.

City kicks off ambitious project to expand the tree canopy that benefits us all
KNOXVILLE — The people in this city sure seem to love their trees.
There is at least one tree for every two people who live within the city limits, but officials say they want to add even more over the next 20 years.
How many should be planted is currently up in the air, as is the right mix of species and where they should go.
Those are just some of the questions that will be answered in coming months as the Knoxville Urban Forest Master Plan is developed by officials from the city and the non-profit group Trees Knoxville in conjunction with several other agencies and interested citizens.

Contribute to the master plan to grow tree canopy in Knoxville
KNOXVILLE — No matter where you are in the city, you’re not far from a patch or two of trees.
These copses range from small groupings of oaks or dogwoods that are commonly used to mark property boundaries to lush belts of temperate mixed-hardwood forest that sprawl across hundreds of acres.
While Knoxville may be blessed with an abundance of these urban forests, many local residents and leaders believe it’s nowhere near enough.

Jefferson County views and values protected with Foothills Land Conservancy easement

JEFFERSON CITY — Can you see the Sleeping Lady?
We are standing on the back porch of the historic Isaac McBee House, built in 1850, and I follow Jack Kramer’s gaze across the back lawn, over McBee Island flanked by the cold March waters of the Holston River, and to the mountains in the distance.
“She’s easier to see this time of year,” he says, because those distant hills are unobscured by the foliage of trees still nakedly waiting for spring. Indeed, I can see her — she lies with her head to the west and her toes stretched out to the east, the hills forming the rise and fall of her body.
Park releases Smokies air-tour plan
GATLINBURG — Great Smoky Mountains National Park and other federal officials completed a management plan to formally regulate aircraft tours over the park.
Don’t expect much to change in the skies over the park: The plan allows 946 air tours a year by select helicopter operators, unchanged from the average number of annual flights recorded from 2017 to 2019. Flights may only operate from two hours after daybreak to two hours before sundown.
“The plan establishes measures to protect park resources including natural and cultural resources, preservation of wilderness character, and visitor experience,” according to Smokies officials. Flights will be restricted to six routes over the park, and must maintain an elevation above 2,700 feet of the highest terrain. Cades Cove is off limits, as are several historical sites, including the Walker Sisters Cabin.
Air tours, often to the dismay of many hikers and others, have occurred over the park for most of its history, but no formal flight guidelines were in place.
“We appreciate the tireless work that went into the development of the Smokies air tour management plan,” said Superintendent Cassius Cash. “The plan incorporates several improvements that allow continued air tour activity, while at the same time better protecting the wilderness character of the backcountry, wildlife populations, natural soundscapes, and the visitor experience in historic areas like Cades Cove.”
Eastern Band of Cherokee Indian members provided notable input into the development of the plan, which will go into effect in 90 days from Dec.3.
Hellbender Press previously reported on development of the Smokies aircraft management plan.
UT forestry efforts benefit whiskey and ecological chasers
KNOXVILLE — Volunteers, distilleries and two universities came together this fall to collect white oak acorns to ensure the survival of the species for commercial and ecological purposes.
It was a key part of a conservation effort started by distilleries worried about the future of oak barrels and casks used to age whiskey and bourbon.
It’s about more than that though, as white oaks have many uses not just for people but for an estimated 2,000 other species, including bats, birds, turkeys, deer, rabbits and hundreds of butterflies and moths. But because the trees are slow to grow, they may be at risk, especially as the region grapples with the uncertain outcomes of climate change.
Real or fake Christmas trees? Like most things in life, the answer is a function of time.
Nothing beats the fresh aroma of a live Christmas tree, if you are into that kind of thing, but both real and fake trees carry their own load of sustainability pros and cons.
Live trees offer holiday beauty and scent and are a traditional addition to households. But they are harvested from a vast monoculture and require multiple levels of carbon-burning transport.
Artificial trees offer convenience, and can be reused for a decade. But they are largely made of plastic, manufactured in places with unsavory human rights records, and require global transit.
This article breaks it down pretty well. Maybe it’s just best to not have a Christmas tree?
