The hour-long report on the fossil-industry and right-wing climate science denial movement broadcast on PBS Frontline Tuesday night raises a key issue. Did deniers win their fight to stop action on global warming by killing it in Congress and keeping it out of the presidential campaign?

"Penn State University scientist Michael Mann, whose work showed that Earth’s temperatures have risen along with increased fossil fuel use, announced Tuesday he had filed a lawsuit against the conservative National Review and the Competitive Enterprise Institute for defamation, complaining that they falsely accused him of academic fraud and compared him to convicted child molester Jerry Sandusky."

"L'AQUILA, Italy -- Six scientists and a government official were sentenced to six years in prison for manslaughter by an Italian court on Monday for failing to give adequate warning of an earthquake that killed more than 300 people in L"Aquila in 2009."

"BRUSSELS -- The European Food Safety Authority said Thursday it cannot accept an 'inadequate' report by a French scientist on a link between cancer and genetically modified corn."

"The EFSA said an initial review showed that the 'design, reporting and analysis of the study ... are inadequate,' meaning it could not 'regard the authors' conclusions as scientifically sound.'

"ANCHORAGE, Alaska — The group aiming to develop a giant copper and gold mine in the Bristol Bay area is vetting the scientific studies that underlay its work, turning to a Colorado-based non-profit with expertise in environmental conflict resolution. But critics of the proposed Pebble mine are having little of it."

Nancy Rabalais, a marine ecologist dedicated to studying the "dead zones" in the Gulf of Mexico and elsewhere, has won one of this year's MacArthur "genius" grants. Rabelais directs the Louisiana Universities Marine Consortium in Chauvin, La., and, since the mid-1980s, she has conducted the major monitoring program collecting basic data on seasonal oxygen levels and nutrients in Gulf waters.
