Satellite data spotted a surprising hot spot of the potent heat-trapping gas methane over part of the American southwest. Those measurements hint that U.S. Environmental Protection Agency considerably underestimates leaks of natural gas, also called methane. In a new look at methane from space, the four corners area of New Mexico, Colorado, Arizona and Utah jump out in glowing red with about 1.3 million pounds of methane a year. That’s about 80 percent more than the EPA figured and traps more heat than all the carbon dioxide produced yearly in Sweden. (AP Photo/NASA, JPL-Caltech, University of Michigan)
