"Conservationists touted a major victory Tuesday in their battle to protect Yellowstone grizzly bears when a federal appeals court ruled that wildlife managers erred when they removed Endangered Species Act protection from 'one of the American West's most iconic wild animals.'"

"Naomi Oreskes is a science historian, professor at the University of California, San Diego, and co-author (with Erik Conway) of Merchants of Doubt, a book that examined how a handful of scientists obscure the facts on a range of issues, including tobacco use and climate change. Her seminal paper in the journal Science, 'Beyond the Ivory Tower: The Scientific Consensus on Climate Change,' challenged - back in 2004 - the notion that climate change science was uncertain. Her work has documented the spread of doubt-mongering from an industry practice to a political strategy."
