by Bill McKibben (The Nation) Our leaders thought fracking would save our climate. They were wrong. Very wrong.   …   Meet methane, otherwise known as CH₄.  In February, Harvard researchers published an explosive paper in Geophysical Research Letters. Using satellite data and ground observations, they concluded that the nation as a whole is leaking methane in massive quantities. Between 2002 and 2014, the data showed that US methane emissions increased by more than 30 percent, accounting for 30 to 60 percent of an enormous spike in methane in the entire planet’s atmosphere.

To the extent our leaders have cared about climate change, they’ve fixed on CO₂. Partly as a result, coal-fired power plants have begun to close across the country. They’ve been replaced mostly with ones that burn natural gas, which is primarily composed of methane. Because burning natural gas releases significantly less carbon dioxide than burning coal, CO₂ emissions have begun to trend slowly downward, allowing politicians to take a bow. But this new Harvard data, which comes on the heels of other aerial surveys showing big methane leakage, suggests that our new natural-gas infrastructure has been bleeding methane into the atmosphere in record quantities. And molecule for molecule, this unburned methane is much, much more efficient at trapping heat than carbon dioxide.

The EPA insisted this wasn’t happening, that methane was on the decline just like CO₂. But it turns out, as some scientists have been insisting for years, the EPA was wrong. Really wrong. This error is the rough equivalent of the New York Stock Exchange announcing tomorrow that the Dow Jones isn’t really at 17,000: Its computer program has been making a mistake, and your index fund actually stands at 11,000.

And Obama was never shy about taking credit for at least part of the boom. Public research dollars, he said in 2012, “helped develop the technologies to extract all this natural gas out of shale rock—reminding us that government support is critical in helping businesses get new energy ideas off the ground.”

Obama had plenty of help selling natural gas—from the fossil-fuel industry, but also from environmentalists, at least for a while.

…

Because here’s the unhappy fact about methane: Though it produces only half as much carbon as coal when you burn it, if you don’t—if it escapes into the air before it can be captured in a pipeline, or anywhere else along its route to a power plant or your stove—then it traps heat in the atmosphere much more efficiently than CO₂. (Robert) Howarth and (Anthony) Ingraffea 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.

To say that no one in power wanted to hear this would be an understatement. The two scientists were roundly attacked by the industry; … An MIT team, for instance, had just finished an industry-funded report that found “the environmental impacts of shale development are challenging but manageable”; one of its lead authors, the ur-establishment energy expert Henry Jacoby, described the Cornell research as “very weak.” One of its other authors, Ernest Moniz, would soon become the US secretary of energy …

…

The trouble for the fracking establishment was that new research kept backing up Howarth and Ingraffea. In January 2013, for instance, aerial overflights of fracking basins in Utah found leak rates as high as 9 percent.

…

The EPA’s old chemistry and 100-year time frame assigned methane a heating value of 28 to 36 times that of carbon dioxide; a more accurate figure, says Howarth, is between 86 and 105 times the potency of CO₂ over the next decade or two.

…

One obvious conclusion from the new data is that we need to move very aggressively to plug as many methane leaks as possible.

…

Also, containing the leaks is easier said than done: …

With that in mind, the other conclusion from the new data is even more obvious: We need to stop the fracking industry in its tracks, here and abroad.

…

We’ve reached the point, that is, where the idea of natural gas as a “bridge fuel” to a renewable future is a marketing slogan, not a realistic claim (even if that’s precisely the phrase that Hillary Clinton used to defend fracking in a debate earlier this month).

…

When Hillary Clinton took over the State Department, she set up a special arm, the Bureau of Energy Resources, after close consultation with oil and gas executives. This bureau, with 63 employees, was soon helping sponsor conferences around the world. And much more: Diplomatic cables released by WikiLeaks show that the secretary of state was essentially acting as a broker for the shale-gas industry, twisting the arms of world leaders to make sure US firms got to frack at will.

Bernie Sanders, by contrast, has called for a moratorium on new fracking.   READ MORE
