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.”

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. Yet, widespread public skepticism persists, and comprehensive policy responses have remained elusive.

On 29 October, 2015, a daylong symposium will 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.

The event is free and open to the public, but seating is limited, and pre-registration is required.
