The implications of changing environmental conditions are increasingly recognized as threats to human, national and international security now and in the future. This Town Hall provides an opportunity to enhance understanding of the nature of these challenges and encourage consideration of ways to strengthen and expand the critical partnerships necessary to ensure that the AMS Weather, Water and Climate Enterprise can and will actively contribute to addressing these challenges.Through a series of paired presentations, the Town Hall will provide an explanation of select challenges from the perspective of organizations charged with responding coupled with examples of how the Enterprise informs their efforts. This approach is consistent with the Meeting’s theme of “Linking Information to Knowledge to Society.” Organizers anticipate addressing challenges and opportunities related to: extreme weather events; climatic anomalies and changes in food, water, and energy security; and extending partnerships with other disciplines and analytical communities to support decision-making.
