5. But fracking gas leaks methane horribly

Fracking is not good for the climate. Or, to put it a tad more scientifically, “By The Time Natural Gas Has A Net Climate Benefit You’ll Likely Be Dead And The Climate Ruined,” as I wrote two years ago.

New satellite data and surface observations analyzed by Harvard researchers confirm previous data and observations: U.S. methane emissions are considerably higher than the official numbers from the EPA. Significantly, the EPA numbers are mostly based on industry-provided estimates, not actual measurements.

While this new study doesn’t attribute a specific source to the remarkable 30 percent increase in U.S. methane emissions from 2002–2014, many other studies have identified the source of those emissions as leakage of methane from the natural gas production and delivery system.

The central problem for the climate is that natural gas is mostly methane (CH4), a super-potent greenhouse gas, which traps 86 times as much heat as CO2 over a 20-year period. That’s why many studies find that even a very small leakage rate can have a large climate impact — enough to gut the entire benefit of switching from coal-fired power to gas for a long, long time.
