Global Warming’s Terrifying New Chemistry | The Nation
"Two Cornell scientists, Robert Howarth and Anthony Ingraffea, living on the northern edge
of the Marcellus Shale,… began producing a series of papers claiming that if
even a small percentage of the methane leaked—maybe as little as 3 percent—then fracked gas would do more climate damage than coal. And their preliminary data showed that leak rates
could be at least that high: that somewhere between 3.6 and 7.9 percent of methane gas from shale-drilling operations actually escapes into the atmosphere.

In January 2013, for instance, aerial overflights of fracking basins in Utah
found leak rates as high as 9 percent.

“The Harvard paper is important,” venerable climate-policy UC Berkeley PhD Dan
Lashof said. “It’s the most convincing new data I have seen showing that the
EPA’s estimates of the methane-leak rate are much too low
. I think this paper shows that
US greenhouse-gas emissions may have gone up over
the last decade if you focus on the combined short-term-warming impact.”
