Tiny U.s. Region Is Methane 'hot Spot,' Nasa Finds
This map shows anomalous U.S. methane emissions (or how much the emissions differ from average background concentrations) for 2003 to 2009, as measured by the European Space Agency's SCIAMACHY instrument. Purple and dark blue areas are below average. Pale
