"Curbing Climate Change by Sealing Gas Leaks"
"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. ...
Within a few days the leaks had been sealed by workers.
Efforts like EnCana’s save energy and money. Yet they 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."
