The Climate Resilience for Frontline Clinics toolkit guides staff and providers at U.S. clinics that serve uninsured and underinsured populations on how to develop disaster preparedness plans, extreme weather alert systems and health tip sheets to give patients, to better deal with heat waves, hurricanes, wildfires and floods in underserved communities. It was developed by researchers at the Center for Climate, Health, and the Global Environment at Harvard T.H. Chan School of Public Health and the nonprofit Americares and was funded by Biogen.
