Climate scientists worldwide are clear about the cause of global warming: It’s us. Industrial pollution in the form of carbon and methane emissions are heating our planet at an unsustainable rate. While the House has tried to take action to address the problem, the administration and GOP-controlled Senate has adopted a head-in-the-sand approach. The administration is actually rolling back regulations in place to protect us from harmful methane pollution and gutting regulations designed to reduce our carbon emissions. As the second-largest natural gas producing state, Pennsylvania needs to step up to the plate in the absence of federal leadership. Gov. Wolf should put standards in place to cut methane emissions and send a signal to other states to do likewise.
