Addresses mitigation and adaptation to climate change as it pertains to water and health. Focuses on regions where water-borne illness, malnutrition, and vector-borne diseases – problems that will worsen with increasing temperatures and urban overcrowding – represent the top three causes of morbidity and mortality. Includes readings, workshops and films that address water, climate change and health challenges and explore solutions. Field trips include coastal watershed restoration, flood protection, carbon sequestration, and zero-carbon sites in the Boston area. Students complete a term project and/or teach a class, setting the stage for a life-long commitment to communicating climate science to a broad public. Students taking graduate version complete additional assignments.
