ORNL researcher models fire’s growing footprint in a changing climate
ORNL report: Local wildfire danger will likely loom larger because of climate change
OAK RIDGE — This cruel summer, the Southern Appalachian region is already baking in above-normal temperatures and basking in poor air quality.
Air temperatures in Knoxville flirted with 100 degrees on July 6, which were well above average and prompted the National Weather Service to issue a heat advisory for much of the metropolitan area.
It’s hard to definitively link a heat wave to global warming, but one oft-cited consequence of climate change is the growing intensity of wildfires, even in the traditionally moisture-rich Appalachians. The range of climate change effects is difficult to pin down, but one constant in the study of climate change is an expected increase in overall temperatures, which can power wildfires via both fuel increases and volatility.

SACE released its annual utility decarbonization tracking report, and it’s not pretty
Report: Many utilities are not reducing carbon emissions despite public assurances to the contrary
KNOXVILLE — Global greenhouse gas emissions must peak by 2025 and experience rapid and deep reductions to avoid a potentially catastrophic future, according to a new analysis by air-quality and climate advocates. Emissions must reach net zero by the early 2050s to limit warming to 1.5 degrees (C) in order to avoid the worst impacts of the climate crisis.
Many utilities and municipalities have acknowledged this dynamic, but the Southern Alliance for Clean Energy s fourth annual “Tracking Decarbonization in the Southeast" report highlights that current utility resource plans are not in line with this overarching target. Obstacles to getting utilities on track that are discussed in our report include: increasing reliance on fossil gas, underutilizing energy efficiency, and placing limitations on popular technologies such as rooftop solar. There’s still a lot of work to do before any Southeast utility is on track to decarbonize.

Invasive insects are among the vanguard of noticeable climate changes in America’s most-visited national park
GATLINBURG — Ants scurry beneath the carpet of last year’s leaves in Great Smoky Mountains National Park. The native ants are busy spreading the seeds of violets and bloodroot, preparing a new carpet of spring wildflowers to draw thousands of visitors.
But the local insects aren’t alone under there. They have become prey to venomous Asian needle ants that also prowl the leaf litter.
These invaders dine on termites, other ants and insects, while stealing habitat from them. Unlike invasive fire ants, needle ants can live in pristine forests and build large colonies with hundreds of queens. But like fire ants, needle ants have a painful sting that can trigger an allergic reaction.
Climate change is expected to make it easier for invasive species like needle ants to upset the delicate balance of this temperate rainforest full of rare plants and animals. That’s just one example.
