Human health

Climate change is expected to have a number of mostly adverse effects on human health, according to the Intergovernmental Panel on Climate Change, including:

  • heat-related mortality and morbidity
  • mortality and morbidity related to extreme weather.

In addition, the following hazards to human health are predicted:

  • increases in water and food-borne disease
  • changes in seasonality and distribution of vector-borne diseases (that is diseases spread by organisms, such as mosquitoes)
  • increased air pollution (ground-level ozone and particles), and
  • adverse impacts on community and mental health.
