Between the record-breaking global heat and extreme downpours, it’s hard to ignore that something unusual is going on with the weather in 2023.
People have been quick to blame climate change – and they’re right: human-caused global warming plays the biggest role. The weekslong heat wave that started in June 2023 in Texas, the U.S. Southwest and Mexico would have been virtually impossible without it, one study found.
However, the extremes this year are sharper than anthropogenic global warming alone would be expected to cause. September temperatures were far above any previous September, and around 3.1 degrees Fahrenheit (1.75 degrees Celsius) above the preindustrial average, according to the European Union’s earth observation program.
July was Earth’s hottest month on record, also by a large margin, with average global temperatures more than half a degree Fahrenheit (a third of a degree Celsius) above the previous record, set just a few years earlier in 2019.

Appalachian State University research helps farmers and crop yield
This article was provided by Appalachian State University. Hei-Young Kim is laboratory manager and research assistant with the Appalachian Energy Center.
BOONE — The Appalachian State Nexus Project experiments continue to advance agricultural innovations with biochar to help local farmers. Biochar is a charcoal-like material produced from plant material such as grass, agricultural and forest residues that produce carbon-rich material used for agriculture and horticulture purposes.
Adding biochar to soil increases surface area, pH, plant nutrient availability, and enhances water-holding capacity, according to Appalachian State researchers. It also can sequester carbon in the ground for extended periods of time, which may otherwise find its way into the atmosphere as CO2 or methane.
The qualities of biochar vary depending upon the material it comes from — timber slash, corn stalks or manure.
Oak Ridge research suggests rough weather ahead
OAK RIDGE — Researchers from Oak Ridge National Laboratory and Northeastern University modeled how extreme conditions in a changing climate affect the land’s ability to absorb atmospheric carbon — a key process for mitigating human-caused emissions. They found that 88 percent of Earth’s regions could become carbon emitters by the end of the 21st century.
Climate extremes lasting months or years could reduce plant productivity, which governs Earth’s capacity to produce food, fiber and fuel. Events such as wildfires could generate bursts of emissions from carbon stored in forests.
The team used the open-source Community Earth System Model to simulate multiple variables, which enabled a holistic understanding of how climatic conditions interact.
“Our results suggest that meteorological extremes will become more frequent, intense and widespread due to the compound effect of high temperature, drought and fire,” said ORNL’s Bharat Sharma. “Tropical regions may face these to the most extreme degree.”

Climate change could steal your fish
Dan Chapman is a public affairs specialist for the Southeast Region of U.S. Fish and Wildlife Service.
CHEROKEE — The mountains of the Southern Appalachians were scraped clean a century ago. Headwater ecology changed as the canopy of trees disappeared that was shading the streams from all but the noonday sun. Rainstorms pushed dirt and rocks into the water muddying the feeding and breeding grounds of fish, amphibians and insects.
Lower down the mountain, newly cut pastures edged right up to the creeks while cows mucked up the once-pristine waters. Invasive bugs killed hemlocks, ash and other shade-giving trees. Pipes, culverts and dams blockaded streams and kept animals from cooler water.
The trout never had a chance.
Now they face an even more insidious foe — climate change.

Biden-sponsored legislation trickles down to cap defunct Big South Fork oil wells
ONEIDA — Big South Fork National River & Recreation Area (NRRA) received $1 million for the orphaned well reclamation project, funded through the Inflation Reduction Act and Bipartisan Infrastructure Law. This project is part of a nationwide effort to restore natural habitats and address climate change impacts.
In fiscal year 2023, President Biden’s Investing in America agenda, through the Bipartisan Infrastructure Law and the Inflation Reduction Act will provide $52 million to the National Park Service to fund projects throughout the country related to ecosystem resilience, restoration, and environmental planning needs.
The Big South Fork project will plug and reclaim six orphaned well sites throughout the park in Tennessee and Kentucky. The project, funded by the Inflation Reduction Act, will mitigate abandoned mine drainage and close open mine portals at Big South Fork NRRA.
Methane pollution from many of these unplugged wells is a serious safety hazard and is a significant driver of climate change, with methane being more than 25 times as potent as carbon dioxide at trapping heat in the atmosphere.
“Plugging the wells removes abandoned aboveground oil or gas production equipment, improves visitor safety and protects park groundwater and other park resources,” said Big South Fork NRRA Superintendent Niki Stephanie Nicholas in a press release.
“The restoration of these sites through these investments will stabilize access roads and production sites and promote ecosystem health by planting native plant species.”

Here’s an updated summer primer for the end of the world as we know it
Written by Rick VaughanThe Earth’s sun is seen in this NASA image. Scientists said July might be the hottest month in 100,000 years.
The global heat wave of July 2023 has spared Southern Appalachia. So far.
KNOXVILLE — July 2023 has so far offered a scary look at global climate change around the world, and the month is already one for the record books.
This month will likely end up being the hottest July on record, globally speaking. That comes after quantitative conclusions from multiple scientists that the past week was, globally, the warmest in 100,000 years.
The Southern Appalachians have generally been spared from the heat settling on vast portions of the country and world, but that will soon change. The National Weather Service predicts higher than average temperatures flirting with 100 degrees in the Tennessee Valley next week. Record-breaking temperatures are possible. The average high temperature for July in Knoxville is 87 degrees.

Citizens continue call for TVA to adopt sustainable alternatives to coal plants

Solar? Gas? Future of Kingston plant up in the air
KINGSTON — Tennessee Valley Authority is considering whether to go with gas or solar power after it closes the infamous Kingston Fossil Plant in Tennessee.
The plant has stood since 1955 in Roane County. The federal utility plans to close Kingston Fossil plant and is looking at ways to replace the power it generated. It’s asking the public for comments. The utility’s proposals center around replacing the power generated by the plant with either solar generation or natural gas. One option includes replacing the coal-powered plant at the site with a fossil gas plant.
TVA recently proposed to retire three units between 2026 and 2031 and the other six units between 2027 and 2033. Ash spilled from a dike at this plant in 2008. A lawsuit was recently resolved surrounding the health damage to people working on cleaning up the spill. TVA has identified trouble with starting up and shutting down the plant for power generation and technical issues with lower boilers as the reasons for closing the plant, not the spill.

Environmental groups sue Tennessee Valley Authority over proposed new power plant
This story was originally published by Tennessee Lookout.
NASHVILLE — A trio of environmental groups filed suit against the Tennessee Valley Authority, claiming the utility violated federal law by failing to properly evaluate climate, environmental and financial impacts of a proposed new gas-fired plant in Cumberland City, Tennessee.
The lawsuit, filed in a Nashville federal court this month, also claims that TVA quietly inked a deal with an international pipeline company to supply the gas-fired plant, even as it publicly went through the motions of seeking input on alternative sources of power to replace the Cumberland Fossil Plant, its aging coal-fire facility located about 60 miles northwest of Nashville.
The groups are seeking an immediate halt to construction on the gas plant and an order forcing the utility to revise the existing environmental impact study used as the basis for moving forward with the gas-fired plant.
“Our country’s largest utility has gamed the system to fast-track dirty energy projects and that’s why we’re going to court to stop it,” Gaby Sarri-Tobar, a campaigner with the Center for Biological Diversity, said in a statement. “TVA needs to be held accountable for its reckless pursuit of a new fossil gas plant in the midst of the climate emergency.”
To critics’ dismay, TVA plans to replace coal with natural gas. The utility also plans to double its solar supply.
Written by Ben PoundsCitizens call on TVA to stop passing gas
KNOXVILLE — The Tennessee Valley Authority in coming years plans to add both natural gas and solar plants to its portfolio to meet what it says are rising energy demands.
TVA’s Board of Directors laid out the federal utility’s plan in a meeting at Norris Middle School in May. Environmentalists at a previous hearing criticized the utility’s focus on natural gas rather than renewables or other measures. Other people, largely tied to local power providers, argued that a switch to renewable energy would be unreliable.
TVA showed a map in a press release following the meeting, showing four proposed natural gas plants and two proposed solar plants. Two of those natural gas plants would be in Tennessee while the other two are planned for Alabama and Kentucky. It stated these new plants will total 3,800 megawatts. It also spoke of its System Operations Center, set to open in fall 2024 in Georgetown to manage the utility’s grid. TVA also stated a desire to research nuclear technologies.
“Our region is experiencing growth at six times the national average, which means we must invest in our current power system and build new generation so we can continue meeting our region’s demand,” said TVA president and CEO Jeff Lyash.
Several citizens criticized TVA’s focus on natural gas plants and new pipelines at the listening session May 9. Among them was Clinton resident and activist John Todd Waterman.

Enviros cheer new Biden plan to limit fossil pollution
WASHINGTON — The U.S. Environmental Protection Agency on May 11 proposed new carbon pollution standards for coal and gas-fired power plants to protect public health and reduce harmful pollutants.
EPA’s proposed standards are expected to deliver up to $85 billion in climate and public health benefits over the next two decades and avoid up to 617 million metric tons of total carbon dioxide (CO2) through 2042.
EPA estimates that in 2030 alone, the proposed standards will prevent more than 300,000 asthma attacks; 38,000 school absence days; 1,300 premature deaths; 38,000 school absence days; and 66,000 lost work days.
Dr. Stephen A. Smith, Executive Director of Southern Alliance for Clean Energy: “Individuals and communities across the country are doing whatever they can to protect against the immense dangers of climate pollution and are depending on the federal government to do the same. Federal limits on climate pollution from power plants are a critically needed and long overdue protection for public health and the environment.
“We will be reviewing the proposal and hope that the proposal hits the mark in giving our communities the safeguards they need from deadly fossil pollution.”
EPA will be taking comments on these proposals for 60 days after publication in the Federal Register.

Rocking chair rebellion: Older Americans help drive climate activism

As their twilight approaches, elders supercharge climate action on behalf of future generations
This story was originally published by The Revelator. Eduardo Garcia is a New York-based climate journalist. A native of Spain, he has written about climate solutions for Thomson Reuters, The New York Times, Treehugger and Slate. He is the author of Things You Can Do: How to Fight Climate Change and Reduce Waste, an illustrated book about reducing personal carbon footprints.
Thousands of senior Americans took to the streets in March in 30 states to demand that the country’s major banks divest from fossil fuels.
This “rocking chair rebellion” — organized by Third Act, a fast-growing climate action group focused on older Americans — shows that Baby Boomers are becoming a new force in the climate movement.
Third Act cofounder Bill McKibben, who joined a Washington, D.C., protest, says it’s unfair to put all the weight of climate activism on the shoulders of young people. It’s time for older Americans to take a central role.
“Young people don’t have the structural power necessary to make changes,” McKibben tells The Revelator. “But old people do. There are 70 million Americans over the age of 60. Many of us vote, we’re politically engaged, and have a lot of financial resources. So if you want to press either the political system or the financial system, older people are a useful group to have.”

The State of Bats: Grim news for our winged mammals
The big brown bat feeds on beetles, flies, moths, and true bugs, which it catches and eats while in flight. It is widespread across the Southern Appalachians and forages for food by flying slow, straight courses over water, forest canopies, wooded clearings, and around city lights. J. Scott Altenbach via Georgia Department of Natural Resources
North America’s first State of the Bats report gives a sobering outlook for the winged mammals. According to the North American Bat Conservation Alliance report:
- More than half of the 154 known bat species on the continent could face severe population declines over the next 15 years.
- During that time, up to 82 percent of bat species will be negatively affected by climate change, especially extreme drought and temperatures.
- The scope and severity of threats — including habitat loss, wind turbines and the deadly bat disease white-nose syndrome — are increasing.
The news isn’t all bad. The report outlines ways to help and emphasizes the wide-ranging benefits of bats, from improving crop yields to eating insect pests. It also highlights the promise of focused, collaborative conservation efforts.
Case in point, the lesser long-nosed bat was once endangered in Mexico and the U.S. But thanks to international efforts, it is now delisted and recovered in both countries.
The North American Bat Conservation Alliance is another example. The coalition involving the U.S., Mexico and Canada created the 2023 State of the Bats report with Bat Conservation International and others.
“Bats face many challenges and the conservation landscape is increasingly complex,” said Dr. Jeremy Coleman, alliance co-chair and white-nose syndrome coordinator for the U.S. Fish and Wildlife Service. “While there is more to do, the level of international collaboration we have achieved for bat conservation in North America is a bright spot and a cause for optimism going forward.”

How two East Tennessee churches went solar, and can help your congregation do it, too
OAK RIDGE — On two church roofs on the same road in this small town that helped harvest the atom, panels catch the sun’s rays for electric power.
Oak Ridge Unitarian Universalist Church at 1500 Oak Ridge Turnpike and Faith Lutheran Church at 1300 Oak Ridge Turnpike added solar energy at different times through different companies using different federal incentives. ORUUC added its panels in 2015; Faith Lutheran added them in March 2022. Members of both churches involved in the solar projects spoke to both the challenges involved and the benefits. They said their churches benefited both financially and spoke of the benefits to the planet.
“I really hope it works well for us as well as for the environment,” said George Smith, associate pastor at Faith Lutheran. “I’m fond of thinking that we’re turning God’s gift of sunshine into a gift of cash for ministry.”
