The Guardian's James Randerson explains how his newspaper came to launch its 'Keep it in the Ground' campaign, backing the global fossil fuel divestment movement — and how, rather than constraining the paper journalistically, the project provided a connection to readers that goes far beyond a click on a website.

For this latest installment of “Between the Lines,” a question-and-answer feature with authors, SEJournal book editor Tom Henry interviewed longtime SEJ member Cynthia Barnett about her third book, “RAIN: A Natural and Cultural History,” which came out in April. It’s a unique, ambitious book that goes beyond climate science and water in general to show how rain itself has been perceived around the world by numerous cultures throughout history. Barnett sees rain as “a unifying force in a fractured world.” She also is the author of two other highly acclaimed books,“Mirage: Florida and the Vanishing Water of the Eastern U.S.” and “Blue Revolution: Unmaking America’s Water Crisis.

The issue re-ignited recently when astrophysicist and climate change denier Willie Soon, affiliated with the Harvard-Smithsonian Center for Astrophysics, was revealed to have taken funding — but not disclosed it — from fossil fuel interests. Now the Smithsonian Institution has said it will tighten its guidelines for disclosure of funding by its researchers.
