On 5 November, 1965, the group now known as the President’s Council of Advisors on Science and Technology (PCAST) cautioned President Lyndon B. Johnson that continued accumulation of atmospheric carbon dioxide resulting from fossil-fuel burning would “almost certainly cause significant changes” and “could be deleterious from the point of view of human beings.”AAAS observes that fifty years later, "the reality of human-caused climate change has been reaffirmed by virtually every leading scientific organization as well as the vast majority of individual climate scientists worldwide." The public is invited to participate in a free day-long scientific symposium to commemorate the 50th Anniversary of the First Official Climate-Change Warning to a U.S. President, to "review what scientific research has revealed over the past 50 years, and offer a forward-looking assessment of the range of scientific, technological, communication, and policy options for the future." Registration is required. More @ AAAS.
