Pennsylvania State Capital Bureau Pennsylvania faces serious threats from climate change, including heavier rainfalls, damaging floods and warmer temperatures, if greenhouse gas emissions are not reduced, according to a new report released by Gov. Tom Wolf’s administration on Wednesday. The Pennsylvania Climate Impacts Assessment 2021 predicts that by the middle of this century (2041 to 2070), the statewide average annual temperature will be nearly 6 degrees hotter than between 1971 and 2000. Besides the rise in temperatures and heat waves, the report warns that inland flooding will occur more often and the 56-mile coastline of the Delaware River’s estuary in southeast Pennsylvania could rise by more than 2 feet by the mid-century, while in northwestern Pennsylvania Lake Erie’s water levels would fluctuate from lows to record highs, reminiscent of 2019.
