Article Photos: Global warming talk heats up, revisits carbon tax 3/3

  FILE - In this Tuesday June 22, 2010 file photo, South Carolina congressional candidate Bob Inglis speaks to the reporters after his loss in the runoff election to Trey Gowdy in Greenville, S.C. A carbon tax has been revived by some on both right and left spectrum of politics and is suddenly the hot topic of opinion pieces and quiet discussions. "I think the impossible may be moving to the inevitable without ever passing through the probable," said Inglis. The Republican lost his seat in 2010 in a primary fight, partly because acknowledged that global warming exists and needs to be dealt with. Now he heads a new group that advocates a carbon tax and the idea is endorsed by former Ronald Reagan economic adviser Arthur Laffer. (AP Photo/ Richard Shiro)
