The nonprofit National Geographic Society has sold its flagship magazine and other media assets to Rupert Murdoch’s 21st Century Fox for $725 million. The deal will turn the nonprofit magazine into a commercial operation. Rupert Murdoch has long come under fire for denying the impact of human activity on climate change. A study published in 2014 by the Union of Concerned Scientists argued more than 70 percent of Fox’s climate change coverage was “misleading.”
