Washington Post: CO2 levels hit highest point yet, even after 15-month idling of transportation, industry and overall carbon emissions.

Initial air pollution reductions during the Covid-19 pandemic had an immediate measurable impact on global and local air quality. Demand for oil dropped by nearly 9 percent. That didn't stop the atmospheric carbon dioxide level from reaching its highest concentration since records began.

It's a sign of how difficult it will be to curb overall global emissions enough to prevent the worst consequences of climate change and global warming.

"Even as international borders closed and global economic activity took a massive hit throughout much of 2020, researchers have found that human-caused emissions rebounded fairly quickly after decreasing sharply early in the pandemic," the Washington Post reported.

“Tracking Decarbonization in the Southeast: Generation and CO2 Emissions,” a report developed by the Southern Alliance for Clean Energy, examines the role electric utilities have played in decarbonizing the power supply over the last decade. The report examines power sector carbon dioxide emissions throughout the Southeast, home to some of the biggest utility systems in the nation.

In the spirit of Thinking Globally, Acting Locally, consider what you can do to help Mother Earth and its inhabitants.

Adopting a more sustainable life style to reduce one’s personal ecological footprint is easier to wish for than to accomplish. Some measures that would reap a significant  environmental benefit, such as making a home more energy efficient, may require a substantial investment of physical effort, time and money that will pay back over time only.

Deliberate choice of clothing, however, is a simple course of action for anyone to start making a big difference in social justice, climate impacts and environmental conservation.

The lack of regional and local vehicle traffic during the pandemic greatly reduced measurable pollution in Great Smoky Mountains National Park.

This is your Hellbender weekend read, and the first in an occasional Hellbender Press series about the effects of the Covid-19 pandemic on the natural world

Great Smoky Mountains National Park shut down for six weeks in 2020 during the Covid-19 pandemic. Recorded emissions reductions during that period in part illustrate the role motor vehicles play in the park's vexing air-quality issues. The full cascade of effects from the pollution reductions are still being studied.

Hellbender Press interviewed park air quality specialist Jim Renfro about the marked reduction of carbon dioxide and other pollutants documented during the park closure during the pandemic, and the special scientific opportunities it presents.  He responded to the following questions via email.

Hellbender Press: You cited “several hundred tons" in pollutant reductions during an interview with WBIR of Knoxville (in 2020). What types of air pollutants does this figure include?
