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.

Use of Forests as Carbon Offsets Fails to Impress In First Big Trial

Project in Bolivia Keeps Trees Standing But Has Little Clear Effect on Emissions

But a report Greenpeace will release Thursday questions the premise of using forest conservation overseas to compensate for U.S. pollution, noting that Noel Kempff envisioned keeping 55 million metric tons of carbon dioxide from entering the atmosphere over 30 years but has lowered that expectation to 5.8 million. The revised estimates do not take into account that logging may have moved to areas to the north, east and southwest of the project. And the report notes that the project’s three corporate underwriters — American Electric Power, BP America and PacifiCorp — overestimated how much carbon the project kept from entering the atmosphere, telling the EPA it accounted for 7.4 million metric tons from 1997 to 2004.
