ABSTRACT
This chapter reviews the current state of research on climate change impacts to human health security. It deals with an overview of climate science, examines research on the influence of climate change on a variety of aspects of health security, and considers a discussion of climate change policy and human health. The implications of climate change for human health security are wide-ranging and profound. The difficulty in establishing the causal links between climate change and health security is that there are few, if any, direct causal links between them. While infectious disease transmission has been a central concern in the climate change and health security discussions, a secondary condition that could have an impact on health security is climate change’s impact on agricultural production and food supplies or food security. Health care access by low-income populations may be a more significant driver of the level of risk than climate induced changes to the environment.
