CHARLOTTE, N. C. – The impact of poor air quality on people's lungs often is felt long before it is seen, but a program by Clean Air Carolina is providing the tools to educators and community members to help them see the invisible.

The AirKeepers Citizen Science program provides materials and low-cost sensors that people can use to monitor air quality right where they live.

Susan Harden, an assistant professor at the University of North Carolina, offers the education to her freshman classes.

"Because of their Citizen Science technology that's very accessible and inexpensive, our students were able to use air-quality monitors," Harden explained. "So, they had the equipment that gave them immediate feedback about their research questions."

Clean Air Carolina has collected more than 10,000 hours of data with its monitors that measure particulate matter, a contributor to the depletion of air quality. The data is uploaded to an online site and is available to scientists and the public to monitor the air.

In recent years, state lawmakers have ordered the shutdown of many air-quality units across the state. Clean Air Carolina hopes the data collected by citizens will help supplement the information.

Kate Ortiz is in Harden's UNC class this semester, and says she was surprised how much particulate matter she found in a school parking lot full of idling cars waiting to pick up students.

"I just learned a lot of new information about air quality that I hadn't had before, so it was an interesting class," Ortiz said. "It definitely influenced my knowledge about how I will be partaking, and contributing my own air pollution."

Harden says the hands-on nature of the program makes a lasting impression on her students.

"They're learning how to be advocates at really, the earliest stages of their college careers," she said. "And so those two things – learning how to do science and learning how to be advocates for the environment – are just two wonderful aspects of the program."

Clean Air Carolina is working with agencies that protect the environment to test the effectiveness of monitors and programs such as this one.

As Virginia Gov. Glenn Youngkin pushes forward on plans to withdraw the Commonwealth from the Regional Greenhouse Gas Initiative (RGGI), environmental activists are raising concerns over the plan.

The multistate compact aims to reduce greenhouse-gas pollution through carbon allowances and capping carbon dioxide emissions. It also funds Virginia's Community Flood Preparedness Fund, a program supporting strategies to mitigate and prevent flooding.

Andrea McGimsey, executive director of Faith Alliance for Climate Solutions, said pulling out of RGGI would end the initiative.

"Our rainfall is just getting a lot harder, we're seeing these deluges like we've never seen before, and the science backs that up," McGimsey pointed out. "Our communities are flooding more and more, and we need to prepare for that, because we know it's going to get worse."

A report commissioned by the governor found participation in the program will drive up energy bills for Virginia residents by about $2.39 cents per month, and more than $1,500 per month for industrial customers. The report's authors also contended the project has not borne out its intended benefits.

Annette Osso, managing director for Resilient Virginia, countered it is because the program is relatively new. Virginia completed its enrollment in RGGI in January 2021, and the Flood Preparedness Fund has only completed three grant rounds so far.

"You're either going to pay for it later, after a flood, or you're going to spend some money up front now to put in the mitigation," Osso contended.

One path the governor could take to back out of RGGI involves Virginia's seven-member Air Pollution Control Board.

Zander Pellegrino, northern Virginia organizer for the Chesapeake Climate Action Network, said Youngkin has been filling the board with his appointees, a process which will conclude tomorrow.

"He's going against the will of the General Assembly," Pellegrino emphasized. "There were numerous attack bills that were introduced this past legislative session that tried to do exactly this, that tried to repeal RGGI. He lost. They were voted down."

The Chesapeake Climate Action Network is organizing a protest outside the state Capitol building tomorrow to protest Youngkin's efforts to pull out of RGGI. At noon, demonstrators will march backward around the building to symbolize the direction they say Youngkin is taking the Commonwealth.

Communities in Maryland have been awarded portions of a $1 million grant to support infrastructure projects such as improving local waterway health and increasing green space in urban areas. Environmental advocates said it can help improve quality of life.

The Chesapeake Bay Green Streets, Green Jobs, Green Towns grant was awarded to 13 projects across Maryland, Pennsylvania, Virginia and West Virginia.

Jana Davis, president of Chesapeake Bay Trust, a Maryland-based partner in the grant, said a lot of the awarded communities will use the funds for stormwater runoff control, which can address flooding.

"It encourages water to soak into the ground instead of flooding local streets," Davis explained. "Getting water to flow through the ground and get filtered helps clean the water so that when it enters natural systems it's cleaner than rolling off the surface of a parking lot where it picks up pollutants and goes right into the local stream or bay."

Stormwater management projects include green roofs and vertical rain gardens. Maryland recipients include community organizations in Baltimore, Mount Rainier, Preston and Columbia. The towns of Emmitsburg, Galena, Glen Echo and Millington also received a share of the grant.

The grant is supported in part by the Environmental Protection Agency and the West Virginia Department of Environmental Protection. It also will help local communities increase the amount of green space, such as tree canopies and conservation meadows.

Davis argued every community should have green space within walking distance of all residents.

"It's so important to have an oasis that's green, that provides both a beautiful space to spend time," Davis contended. "But also a place where air quality is locally just a little bit better, where there's shade and where community amenities can be found, whether it's a park bench or a water feature."

Research has shown tree canopies and urban forests can help cities retain stormwater, provide habitat for animals, reduce summer temperatures and store greenhouse gases. Increasing tree canopies is a goal of cities such as Baltimore. Officials want to get the city to 40% canopy coverage by 2037.

Mapping migration routes is important for conserving species such as pronghorn, so supporters hope Congress will fund mapping efforts.

The United States Geological Survey has published two volumes on migration of ungulates, or hoofed mammals, in the western United States. Michael O'Casey, Pacific Northwest field manager for the Theodore Roosevelt Conservation Partnership, said the second volume highlights Sheldon-Hart Mountain pronghorn movements in southeast Oregon.

"It shows this really neat connection between two of the first wildlife refuges in the country that were set aside for big game, specifically for pronghorn," he said. "The map in that Volume Two really highlights the need for connectivity between those two refuges."

The Biden administration zeroed out funding for wildlife migration mapping in its 2023 budget. Advocates for mapping hope Congress will set aside $5 million so USGS can continue work with state and local stakeholders on developing maps for big game species in the West.

Matt Kaufmann, a USGS wildlife biologist, said migrating species are facing more obstacles in the form of fences, traffic and development.

"The mapping gives us a road map to identify the threats that the migrations face, and also identify some of the conservation opportunities," he said, "and without a map, it's really difficult to proactively manage and conserve these migrations."

Kaufmann said migrating animals travel across privately owned land, public lands and tribal reservations, making management complex. But he said ungulate herds are important to western ecosystems, providing prey for large carnivores such as wolves.

"Most of them are also harvestable game animals," he said, "and the harvestable surplus that is produced by migration provides millions of dollars in revenue to the state wildlife agencies that manage those herds, and also billions of dollars in tourism revenue to wildlife viewers."
