In this May 22, 2014, photo, empty train cars, front, sit in a yard after having their loads of coal unloaded at Norfolk Southern's Lamberts Point coal terminal in Norfolk, Va. As the Obama administration weans the U.S. off dirty fuels blamed for global warming, energy companies have been sending more of America’s unwanted energy leftovers to other parts of the world. It’s a global shell game on fossil fuels that at the very least makes the U.S. appear to be making more progress on global warming than it actually is, because it shifts some of the pollution, and the burden for cleaning it up, onto another country’s balance sheet.
