“Climate change challenges, time for global Environmental Health to act in unison”

26 September:

World Environmental Health Day


“Climate change is increasing risks to human health and to health systems that seek to protect the safety and well-being of populations. The largest health risks will be in those communities and populations currently impacted on by climate related diseases. Direct and indirect health impacts associated with climate change are caused by rising temperatures, altered precipitation patterns as well as increasingly severe and frequent extreme weather events. Direct health impacts arise from hazards such as heat-waves, droughts and storms and indirect impacts come from exposures to disease vectors, air and water pollution. Rising carbon dioxide levels, which contribute to climate change, may also reduce the nutrient value in staple crops. This could increase food insecurity among some populations, particularly those in developing countries.”

  • “Climate change affects the social and environmental determinants of health – clean air, safe drinking water, sufficient food and secure shelter.”
  • “Between 2030 and 2050, climate change is expected to cause approximately 250 000 additional deaths per year, from malnutrition, malaria, diarrhoea and heat stress.”
  • “Reducing emissions of greenhouse gases through better transport, food and energy-use choices can result in improved health, particularly through reduced air pollution.”
