Climate change is already starting to have far-reaching consequences for human health and these risks will grow in the coming decades.
The choices we make now will impact how vulnerable we are to these health risks. Climate variability and change can affect the morbidity and mortality of any health outcome sensitive to weather or climate; decreased water availability and agricultural productivity could affect undernutrition, while changing weather patterns and sea level rise may alter the geographic range, seasonality, and incidence of some infectious diseases, such as malaria.
These risks are not independent, but will interact in complex ways with risks in other sectors. Policies and programs must consider climate change if they aim to facilitate resilient and sustainable societies.
