SACRAMENTO, Calif.— Twenty leading climate experts today called on Gov. Jerry Brown to impose a moratorium on fracking in California. In a letter delivered this morning (see PDF), retired NASA climate scientist James Hansen of Columbia University, Michael Mann of Penn State University, Michael MacCracken of the Climate Institute, Ken Caldeira of the Carnegie Institution for Science, Anthony Ingraffea of Cornell University and other experts say fracking and other extreme oil and gas extraction techniques disrupt the climate and harm California’s efforts to be a leader in reducing greenhouse gas emissions.
