Monitoring and evidence on climate change and health

WHO coordinates reviews of the scientific evidence on the links between climate change and health and helps to shape a global research agenda.

Working closely with health ministries and research centers around the world, WHO gathers and analyses information about climate change health impacts and the level of preparedness of different countries to deal with these.

Through a series of health and climate change country profiles, WHO monitors the health impacts of climate change and the progress in building climate resilient health systems in a wide range of countries.

WHO conducts research and collects evidence on the opportunities for health gains from mitigation of Short-Lived and other climate pollutants. These health co-benefits far outweigh the costs of meeting climate change goals and are an important driver for the socio-political acceptance of the necessary changes across sectors.

Human health is strongly determined by environmental health, such as through ecosystem goods and services, biodiversity, land degradation and desertification, water services and urban health. WHO monitors the environmental determinants of health, as well as the public health implications of global environmental change.
