FiveThirtyEight Apologizes On Behalf Of Controversial Climate Science Writer

NEW YORK -- Two prominent climate scientists say Roger Pielke Jr., a controversial writer at Nate Silver’s FiveThirtyEight site, sent emails threatening possible legal action in response to their criticism of his findings for the data-driven news site. Pielke says it's "ridiculous" to characterize the emails as threats against Michael Mann, director of the Earth System Science Center at Pennsylvania State University, and Dr. Kevin Trenberth, a distinguished senior climate scientist at the National Center for Atmospheric Research. FiveThirtyEight, however, apologized to both men.
