The New York Times Dot Earth blog ran an interesting story on recently published research on gas leakage at drilling sites. Predictions had ranged widely, but the results suggest that the amount of methane that escapes in the drilling process is lower than expected (and feared). That’s good news for the many residents of PA who live within eye sight of a well, and for the climate in general. But questions still remain about the impact of the drilling process on the environment. This was the first of a number of papers published from a large research study. I’m curious to see the others.
