Quantitative risk assessment of the effects of climate change on selected causes of death, 2030s and 2050s
WHO releases a quantitative assessment of the health impacts of climate change. This constitutes an update and a further development of the assessment that was first published by WHO for the year 2000, now with a wider range of health impacts, and projections for future years.
The assessment takes into account a subset of the possible health impacts, and assumes continued economic growth and health progress. Even under these conditions, it concludes that climate change is expected to cause approximately 250 000 additional deaths per year between 2030 and 2050; 38 000 due to heat exposure in elderly people, 48 000 due to diarrhoea, 60 000 due to malaria, and 95 000 due to childhood undernutrition. Results indicate that the burden of disease from climate change in the future will continue to fall mainly on children in developing countries, but that other population groups will be increasingly affected.
