Gas Leaks from Fracking Accelerate Global Warming

UPDATE Jan 2013:

Yet another study reveals fracking has a huge problem of gas leaks. Up to  9% of the gas pumped out of the ground leaks into the atmosphere according to a study by National Oceanic and Atmospheric Administration (NOAA) published in Nature  Jan 3, 2013. Natural gas (methane) is a powerful greenhouse gas. If these leaks are widespread, fracking is worse than burning coal accelerating global warming.

In Jan 2012 I detailed new research showing that replacing coal with natural gas from fracking does little to fight climate change (see below). Two studies published in the months after that made an even stronger case that fracking for natural gas is very likely a HUGE MISTAKE:

From Nature: Air sampling reveals high emissions from gas field. Methane leaks during production may offset climate benefits of natural gas.

From Environmental Research Letters: New study demonstrates switching to natural gas is the path to climate disaster. What’s needed is an aggressive deployment of zero-carbon technologies and conservation.

Shale Gas Worse Than Coal Study Finds

By Stephen Leahy

UXBRIDGE, Canada, Jan 24, 2012 (IPS)

Hundreds of thousands of shale gas wells are being “fracked” in the United States and Canada, allowing large amounts of methane, a highly potent greenhouse gas, to escape into the atmosphere, new studies have shown.

Shale gas production results in 40 to 60 percent more global warming emissions than conventional gas, said Robert Howarth of Cornell University in New York State.

“Shale gas also has a larger greenhouse gas footprint than oil or coal over the short term,” said Howarth, co-author of a study called “Venting and Leaking of Methane from Shale Gas Development” to be published in the journal Climatic Change.
