Invasive snails have gained a foothold in Pennsylvania, crowding out native species. We join a team surveying Lake Erie for mysterysnails.  We talk to people dealing with the latest summer heat wave about their thoughts on climate change.  And a new documentary takes a fresh look at the life and death of coal in Appalachia. Plus, we take a look at what’s next for Hays Woods, Pittsburgh’s newest city park.

We have news about PFAS, Pennsylvania’s Trail of the Year, and spotted lanternflies in Pittsburgh.
