No to Keystone, Yes to Crazy (The New York Times, March 9, 2013)

NYT columnist Thomas Friedman references Dr. Verleger's latest article in The International Economy in this op-ed piece: "It’s great that shale gas is replacing coal as a source of electricity, since it generates less than half the carbon dioxide. As the oil economist Philip Verleger Jr. notes in the latest edition of the journal International Economy, these breakthroughs will also lead to much more oil and gas at lower prices, which will help American consumers, manufacturers and jobs. But, he adds, “it will be harder and harder to push for renewable energy programs as hydrocarbon prices fall,” and “the new technologies that allow us to tap shale oil and shale gas could release vast quantities of methane” if not done properly. Methane released in the atmosphere contributes much more to climate change than CO2."
