New scientific research has shed further doubt on claims about the environmental benefits of the natural gas drilling process known as fracking. Researchers with the National Oceanic and Atmospheric Administration and the University of Colorado say methane may be escaping from gas sites at much higher rates than previously thought. Data suggests as much as 9 percent of total methane produced may be leaking. Methane is many times more powerful than carbon at contributing to global warming.
