Session Description: In response to a request from Congress, the National Academies have launched America's Climate Choices, a suite of coordinated activities that will examine the serious and sweeping issues associated with global climate change, including the science and technology challenges involved, and provide advice on actions and strategies the nation can take to respond (http://americasclimatechoices.org). The purpose of this town hall meeting is to solicit community input on the questions and topics the study should address in order to yield a broad, action-oriented, and authoritative set of analyses to inform and guide climate change responses across the nation. Thomas Wilbanks, Marilyn Brown, Diana Liverman, and other study participants and staff will provide an overview of study activities and lead a group discussion.
