The impacts of climate change on human health are a major concern, particularly for populations with known health disparities. In response to this pressing public health issue, in 2010 The San Francisco Department of Public Health created its Climate and Health Program. The goal of the program is to help San Francisco develop ways to anticipate health effects of climate change by applying climate science, predicting health impacts, and preparing flexible programs. The Climate and Health program receives funding from the CDC to participate in the Climate-Ready States and Cities Initiative. The products of our Climate and Health Program are summarized at our website http://www.sfclimatehealth.org.
