April’s show discussed methane emissions, the main component of natural gas and a highly potent greenhouse gas — and their consequences for Pennsylvania in the natural gas age. Methane, 80 times more potent than carbon dioxide over a near-term time frame, is responsible for about one-fourth of the global warming today. The show welcomed Andrew Place, Vice Chairman of the Pennsylvania Public Utility Commission, as its featured guest, while a roundtable discussion composed of Sam Robinson from Governor Tom Wolf’s Office of Policy and Planning, Andrew Williams of the Environmental Defense Fund, and PEC’s John Walliser continued the discussion.
