Coming up at 1:00 this afternoon, WFPL will air “Gas Planet: The Impact of the Natural Gas Boom on Climate Change.” This hour-long documentary produced by The Allegheny Front examines the rise of natural gas, fueled by low prices, abundant resources and a lower carbon footprint than coal. But there are environmental effects tied to natural gas fracturing–or “fracking”–in nearby West Virginia, Pennsylvania, New York and Ohio. And then there are concerns about the effect methane, a greenhouse gas, could have on climate change.
