Conversations with David Whitford In recent years, a partisan political climate and noisy media landscape together have created an environment where science is easily drowned out by misinformation or manipulated by private interests. Meanwhile, our leaders grapple with some of the most complex and daunting problems in history, such as climate change, the spread of nuclear weapons, and transition to a clean energy economy. Kevin Knobloch, Arlington resident and president of the Union of Concerned Scientists (UCS), will discuss how the UCS’s Center for Science and Democracy works to restore the essential role of science, evidence-based knowledge, and constructive debate in US policymaking. This event is co-sponsored by the League of Women Voters in Arlington.
