In June the nonprofits Physicians for Social Responsibility and Concerned Health Professionals of New York released the sixth edition of a compendium that summarizes more than 1,700 scientific reports, peer-reviewed studies and investigative journalism reports about the threats to the climate and public health from fracking.

The research has been piling up for years, and the verdict is clear, the authors conclude: Fracking isn’t safe, and heaps of regulations won’t help (not that they’re coming, anyway).

“Across a wide range of parameters, from air and water pollution to radioactivity to social disruption to greenhouse gas emissions, the data continue to reveal a plethora of recurring problems and harms that cannot be sufficiently averted through regulatory frameworks,” write the eight public health professionals, mostly doctors and scientists, who compiled the compendium. “There is no evidence that fracking can operate without threatening public health directly and without imperiling climate stability upon which public health depends.”
