The extent of human health risks from extreme weather and climate events depends not just on exposure to these events, but also on the status of the public health and health care systems, built environment, and natural environment, and on the capacity of individuals and communities to understand the risk, and avoid, prepare for, cope with, and recover from extreme events. The panelists will explore how recent scientific understanding of the magnitude and pattern of possible impacts, and of the effectiveness of measures to communicate and manage risks, can inform local to national policy development.
