Winner of the PROSE Award for Physical Sciences and Mathematics: Environmental Science The Presidents and the Planet recounts the story of the world’s greatest environmental dilemma through the eyes of early climate change pioneers. It begins in the 1950s, when American scientists first warned about the risks of pollution altering the natural climate in dramatic ways, the national media began covering the matter, and experts first offered testimony to congressional committees on the topic. The story ends in the early 1990s, by which time global efforts to confront the challenge were advancing, while political turmoil had begun to undermine U.S. leadership’s ability to address current and future environmental threats. While some early proponents endorsing climate action are well known, many of the major players have gone largely unrecognized. The oceanographer Roger Revelle exerted influence on eight White Houses during his life and even one after his death, when his former student Al Gore assumed the office of vice president. William Nordhaus had already written seminal studies on climate change when President Jimmy Carter appointed him to the Council of Economic Advisors. Four decades later, the Yale professor won the Nobel Prize in economics for his work on the subject. John Chafee, a Republican from Rhode Island, chaired the Senate’s first committee on the problem and provided concrete solutions to face the dangers of a warming planet during the Reagan administration. The drama reached a full pitch during the George H. W. Bush years, as vocal advocates for climate action and staunch foes of government regulation wrestled over the direction of U.S. energy and environmental policy. To better trace the evolving climate debate in America, author Jay Hakes inspected the archives and writings of prominent scientists and the pivotal reports of the National Academy of Sciences, and traveled to presidential libraries to discover how commanders-in-chief and their science, economic, and political advisors addressed the issue. The Presidents and the Planet affords fresh perspectives that will alter the public’s understanding of when officials first grasped the dire consequences of climate change.
