Coniferous trees once figured prominently in the makeup of Penn's Woods, but their populations never fully recovered from the deforestation of the nineteenth century. Now Pennsylvania's conifers face a new threat: invasive competitors and pests, warmer and wetter weather, and other disruptions linked to climate change.

We explore an evergreen topic with Joe Stavish of Tree Pittsburgh in advance of the group's upcoming Conifer Symposium on June 14.

Of America's ten most endangered waterways, as ranked by the group American Rivers, two can be found in Pennsylvania. While the problems they face are very different, the Ohio and Lehigh rivers both illustrate how intimately connected water issues are with human activity and a changing climate -- not just in the northeastern U.S., but nationwide.

The Pennsylvania Wilds is in the midst of an economic revival based on nature and outdoor recreation, but local leaders and residents worry their success could be undone by military jets flying at very low altitudes over protected public lands. With public comment now being accepted, we look at concerns about the Maryland Air National Guard's plans to expand training operations over one of Pennsylvania's wildest areas.

When people vote to raise their own taxes to fund conservation programs, it's noteworthy. When it happens in a deeply conservative rural community, it's unusual. But when the proposal passes by a four-to-one margin, it's a mandate -- and then some.

How did the campaign for Carbon County's open space initiative achieve such a blowout? And could other Sixth Class PA counties do the same? Organizer Dennis DeMara has answers.

The Infrastructure Investment and Jobs Act of 2021 will deliver unprecedented federal funding for alternative transportation by way of the Carbon Reduction Program. What might that mean for southeastern PA's Circuit Trails initiative? We discuss with Matthew Edmonds of the Montgomery County Planning Commission.

Oil and gas companies pay the U.S. government for the opportunity to drill on public lands, but they only pay royalties on natural gas that's captured and sold. When it's not worth the trouble of bringing it to market, companies either flare off surplus methane or simply release it into the atmosphere, where its near-term climate impact is worse than carbon dioxide's. A new Environmental Defense Fund report documents the amount of gas being wasted as well as the cost to taxpayers, consumers, and the environment.

Pennsylvania's state legislature is divided for the first time in more than a decade, and its new Democratic governor is looking for common ground to govern with bipartisan support. One of his Republican predecessors found that common ground in the environment.

On the eve of what could be an especially contentious legislative session, we revisit our 2020 conversation with former governor Tom Ridge.

Could Pennsylvania's underground rock formations become a reservoir for captured greenhouse gas emissions? With a newly funded soil sample storage facility on the way, the Pennsylvania Geological Survey is in a better position to find out. We chat with Assistant State Geologist Kristin Carter.

2023 is already shaping up to be a big year for environmental policy and legislation, especially around matters of energy and climate. We review the agenda with PEC's Senior VP for Legal and Government Affairs, John Walliser.

Pennsylvania's landscape is riddled with abandoned oil and gas wells that were never properly shut down and sealed up, including hundreds of thousands for which the responsible parties can't be identified, or no longer exist. Between inadequate bonding requirements for operators and a chronically underfunded remediation program, DEP is fighting an uphill battle. But private well-plugging efforts like the Well Done Foundation are stepping up to help meet the need. As founder Curtis Shuck explains, they're also exploring innovative ways to finance the work.
