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.

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.
