This activity is being carried out by Resolute Forest Products. This is a rapidly developing story. Aside from the…

From MMFA: Broadcast networks are decreasing their climate coverage at a time when the case for reporting on the issue is become more and more compelling. By ignoring this serious matter, media are failing to inform audiences about pressing impacts on human migration patterns, women, and the economy. In 2016, media had no shortage of…

From Chris Mooney and Juliet Eilperin at the Washington Post: The Environmental Protection Agency announced Friday evening that its website would be “undergoing changes” to better represent the new direction the agency is taking, triggering…
