Ralph Cicerone, head of the National Academy of Sciences, will provide a take-home message on what the scientific community in general and the AMS community in particular can do to increase their credibility with the public. Cicerone has been thinking deeply about how the practice of science and the behavior of individual scientists can be improved. As much as listening, communication is based on some level of trust. And, just as the Tuesday event should provide a teachable moment about how we influence our environment, the ”Climategate” e-mails were a teachable moment about human frailty being a part of the practice of science. The current political climate has been reinforced by Climategate and by a few errors in the Intergovernmental Panel on Climate Change’s (IPCC) report, damaging the trust the public feels not only in climate science, but also toward science in general. Viewing this in a positive manner, provides an incentive to redouble the efforts of all scientists in promoting ethical professional conduct and improving the way the business of science is done and the manner in which scientific findings are communicated to the public. For additional information on the 2011 Presidential Town Hall, please contact AMS President Peggy LeMone (e-mail: amspresident@ametsoc.org).
