The Four Corners area (red) is the major U.S. hot spot for methane emissions in this map showing how much emissions varied from average background concentrations from 2003-2009 (dark colors are lower than average; lighter colors are higher). Image Credit: NASA/JPL-Caltech/University of Michigan A new study of satellite data by scientists at NASA and University of Michigan One shows that one small “hot spot” in the American Southwest produces the greatest concentration of the greenhouse gas methane in the United States.
