"The good news: A sample of what are probably the best fracked wells in the country finds low emissions of methane, a potent heat-trapping gas. The bad news: The study likely missed the super-emitters, the wells that are responsible for the vast majority of methane leakage."

"The ugly news: Same as ever — natural gas from even the best fracked wells is still a climate-destroying fossil fuel. If we are to avoid catastrophic warming, our natural gas consumption has to peak sometime between in the next 10 to 15 years, according to studies by both the Center for American Progress and the Union of Concerned Scientists."
