Great Smoky Mountains National Park on Monday announced that Alan Sumeriski, a veteran park infrastructure manager in the nation's most-visited national park, will take the helm as deputy superintendent.

“Alan is a well-respected senior leader in the National Park Service with over 30 years of experience in managing some of the most complex operations in the National Park Service and I’m honored to select him as the next deputy superintendent of the Smokies,” Superintendent Cassius Cash said in a press release announcing Sumeriski's new assignment. “As acting deputy superintendent, Alan has consistently provided strong and innovative parkwide leadership to help us meet the challenges of today and tomorrow.”

Sumeriski has served as the heavily visited national park's facilities management chief since 2007. His first assignment was as an engineering equipment operator for park service units in the Washington/Baltimore area.

“Alan provides leadership for over 150 permanent and seasonal staff who care for 384 miles of roads, 146 bridges, 152 historic cemeteries, 27 water and sewer systems, 10 campgrounds, 11 picnic areas, 848 miles of trails, and over 100 historic structures and landscapes,” according to a park release.

NYT: NOAA map details US climate change over last century

The map produced by the National Oceanic and Atmospheric Administration shows that virtually all of the U.S. has higher average temperatures than 100 years ago. The precipitation data shows where rainfall averages have increased (East Tennessee and most of the Appalachian Mountains and their adjacent foothills and valleys) and where they fluctuated beyond average (California and the Southwest). Some of the data predates the regular government weather and climate record-keeping that began 90 years ago.

"Because the normals have been produced since 1930, they also say a lot about the weather over a much longer term. That is, they show how the climate has changed in the United States, as it has across the world, as a result of emissions of heat-trapping gases over more than a century."

SACE: TVA must also wean itself off natural gas and nuclear reliance

As previously reported by Hellbender Press, Tennessee Valley Authority plans to shut down its five remaining coal plants by 2050 and pursue a carbon-neutral future.

TVA board members spoke favorably of the decision at its regular meeting on Thursday.

“TVA CEO Jeff Lyash shared a vision of how TVA will continue to support the Valley for years to come with a commitment to sustainability. The board also endorsed a strategic focus on decarbonization and a commitment to providing a reliable, low-cost energy supply as TVA moves into the future,” according to a statement released Thursday by TVA.

“TVA leadership issued a Strategic Intent and Guiding Principles document to provide direction for developing business strategies that provide reliable, resilient, low-cost and clean energy to the region. View the Executive Summary of the document.

“TVA’s new Carbon Report outlines TVA’s commitment and path to reduce carbon in the coming years without compromising the reliability and low rates the Valley has come to expect. The report outlines TVA’s leadership today in carbon reduction, our plan to achieve 70 percent reduction by 2030, our path to 80 percent reduction by 2035 and our aspiration to achieve net-zero carbon by 2050.”

Knoxville-based Southern Alliance for Clean Energy generally lauded TVA’s sustainability mission, but released the following detailed response Thursday afternoon:

“The agency’s intentions fall far short of the Biden Administration’s goal of decarbonizing the nation’s electric grid by 2035, a timeframe recommended by scientists to avoid the worst impacts of climate change.

Joy Grissom and Gerry Moll: Preserving East Tennessee’s natural heritage with shovels and wheelbarrows

If there’s a massive ecological disturbance in your neighborhood, who you gonna call?

The Knoxville Native Plant Rescue Squad, of course. 

Joy Grissom and Gerry Moll spent the past six years identifying, digging, hauling and muscling native East Tennessee plants to salvation from construction, grading and logging sites.

The duo has saved thousands of plants and their communities from certain demise. They have plucked plants to safety from areas ranging from a 170-acre logging operation in Cocke County to relatively small commercial developments in Knox County.

NYT: EPA plans stricter regulation of HFC emissions

Hydrofluorocarbons were used on an industrial scale to replace ozone layer-destroying chlorofluorocarbons used in refrigeration, cooling and other applications, but they turned out to be a powerful driver of climate change. Scientists estimate HFCs are 1,000 times more potent than carbon dioxide in terms of their cimate-change role.

Oak Ridge National Laboratory scientists continue research into zero-emission refrigerant technologies. 

According to Times reporting: “In proposing a new regulation, Michael S. Regan, the E.P.A. administrator, said the agency aimed to reduce the production and importation of hydrofluorocarbons, which are used in refrigeration and air-conditioning, in the United States by 85 percent over the next 15 years.”

“Our intelligence and flexibility as a society will be tested as the financial and industrial giants all figure out what they’re going to do.”

The Tennessee Valley Authority intends to phase out its aging fleet of coal plants by 2035, potentially replacing the age-old carbon-rich power source with increased use of natural gas and refreshed, concentrated supplies of nuclear energy as the vast utility moves to drastically reduce its greenhouse gas emissions.

The plan emerged Wednesday, about a month after the Biden administration called on the U.S. power sector to eliminate pollutants linked to climate change by 2035.

The Tennessee Valley Authority is the largest public provider of electricity in the United States. It provides wholesale power to every major municipal provider in Tennessee, as well as other metropolitan areas and smaller utility districts and cooperatives within its seven-state service area.

CItizen Times: Roan Mountain donation will protect vast stretches of forest in Roan Highlands

Epic Games CEO Tim Sweeney donated 7,500 acres to the Southern Appalachian Highlands Conservancy, an area described by an Asheville Citizen-Times reporter as “A high-elevation hideaway for birds, bears and salamanders, a massive piece of Western North Carolina’s famous mountains left unmarred, and a refuge for rare species in the face of climate change...

Mayor wants green for green; some otherwise supportive city residents already aren’t pleased with some initiatives.

KNOXVILLE — Mayor Indya Kincannon’s proposed Knoxville 2020-2021 budget commits some $30 million to reduce city climate impacts, expand its use of renewable energy, invest in urban forest preservation and outdoor recreation assets and improve bus and bicycle travel in communities across the city. The budget also provides money for revitalization of the Burlington District, a historic pedestrian center of Black commerce in East Knoxville.

The city’s net budget is $384 million, which includes a $253 million operating fund.

The budget is just a recommendation to City Council at this point. 

This photo provided by Ijams Nature Center is an example of the plethora of weird things removed from the Tennessee River and its tributaries during the annual River Rescue held March 27. 

Mattresses, rocking horse and plastic shed among the stranger items retrieved from area waterways

Volunteers removed 31,000 pounds from the Tennessee River and its watersheds on March 27 during the 32nd annual Ijams River Rescue despite a storm system that dropped several inches of heavy rain on the area.

The rain dissuaded some of the 717 volunteers signed up for the river rescue, but nearly 500 people still joined together to collect trash from 32 sites. Their nasty haul included 919 bags of garbage and 82 tires, according to a release from Ijams Nature Center. 

The heavy rain actually worked out somewhat in organizers’ favor, as debris and flotsam were flushed from tributaries into the main stem of the river.

“Heavy rain always means more trash because the rising waters wash everything downstream and into the Tennessee River,” Ijams Volunteer Coordinator Madelyn Collins said in the news release. “We are so appreciative to everyone who braved the storms and did the work while they could. It was amazing how much volunteers accomplished in such a short time.”

One lucky participant found a $50 bill; other unusual items removed from the river included a toilet, a recliner, mattresses, a rocking horse, plastic shed and a baby stroller.

“The takeaway from this year’s event—and every other cleanup this community does—is that we need to be more careful about how we dispose of trash and recyclables. If you don’t put it where it belongs, it ends up in our water.”

Tennessee Valley Authority; city of Knoxville Stormwater Engineering; Bio Plumbing, LLC; First Horizon Foundation; Tennessee Wildlife Resources Agency; WestRock CP, LLC; Genera, Inc.; Knoxville TVA Employees Credit Union; Waste Connections of Tennessee Inc.; CAC AmeriCorps; and the Water Quality Forum sponsored, supported or participated in the annual cleanup.
