Methane leaks: cheap to fix and crucial; ny times;

[amborin]

To the naked eye, there was nothing to be seen at a natural gas well in eastern Texas but beige pipes and tanks baking in the sun.

But in the viewfinder of Terry Gosney’s infrared camera, three black plumes of gas gushed through leaks that were otherwise invisible.



"some three trillion cubic feet of methane leak into the air every year, with Russia and the United States the leading sources, according to the Environmental Protection Agency’s official estimate. (This amount has the warming power of emissions from over half the coal plants in the United States.) And government scientists and industry officials caution that the real figure is almost certainly higher.


in 2006 the E.P.A. estimated that Russia, the world’s largest gas producer, ranked highest, with 427 billion cubic feet of methane escaping annually, followed by the United States at 346 billion, Ukraine at 225 billion and Mexico at 191 billion.

are also a cheap, effective way of blunting climate change that could potentially be replicated thousands of times over, from Wyoming to Siberia, energy experts say. Natural gas consists almost entirely of methane, a potent heat-trapping gas that scientists say accounts for as much as a third of the human contribution to global warming.

“This for me is an absolute no-brainer, even more so than putting in those compact fluorescent bulbs in your house,” said Al Armendariz, an engineer at Southern Methodist University who studies pollutants from oil and gas fields.

Acting quickly to stanch the loss of methane could substantially cut warming in the short run, even as countries tackle the tougher challenge of cutting the dominant greenhouse emission, carbon dioxide, studies by researchers at the Massachusetts Institute of Technology suggest.

Unlike carbon dioxide, which can remain in the atmosphere a century or more once released, methane persists in the air for about 10 years. So aggressively reining in emissions now would mean that far less of the gas would be warming the earth in a decade or so.

Within a few days the leaks had been sealed by workers.

1. That's about 47 million US tons

Basically, the facts are saying we're adding 0.00539% to the methane content of our atmosphere each year through leaks.

Thanks for the thread, amborin.
