Climate change related to global warming is the world’s most urgent public health problem (Stott BMJ 2006) Climate change has been called the defining issue for public health in the 21st century. (Chan, 2007) Climate change related to global warming is the world’s most urgent public health problem (Stott BMJ 2006) Climate change has been called the defining issue for public health in the 21st century. (Chan, 2007)
Health Impacts of Climate Change Direct impacts Temperature related Extreme weather events Indirect impacts Air pollution related Water and food borne contamination Vector borne and zoonotic diseases Socio-economic impacts on communities
The French Heat Wave 2003 Daily Mortality in Paris Source: INVS, 2003
Number of hot days above 30 C Heat Waves in Canadian Cities Environment Canada 2005
Heat, Air Pollution and Weather Related Mortality in Toronto Air Pollution Acute air pollution related elevated mortality # Days with temp >30 0 C Heat alerts Heat related elevated mortality Cold related mortality Annual mean # (1954- 2000) 82282.5120105 Predicted 2080 (based on a 3 fold increase in CO2) Substantial increase in high pollution days (esp Ozone related) 25-30% increase, to 1070 4 fold increase 4 fold increase in hot weather warnings 3 fold increase (360) 60% decrease Derived from Toronto Public Health. Influence of Weather and Air Pollution on Mortality in Toronto: Summary Report (Pengelly et al., 2005)
Allergies Length of Season Increased Pollen Counts Synergism with Ozone
Storms, floods, drought Less developed countries: more vulnerable Direct injuries Indirect Damage PTSD, anxiety, depression Socio-political unrest and Population Displacement Drought Water scarcity Malnutrition, infant mortality Fires
Impact in Developing Countries By 2000, climate change since the 1970s was causing over 150,000 additional deaths per year (WHO, 2002) Malnutrition; Gastro-enteritis; malaria Sea level rise
Indirect impacts on international health Water Food security Extreme climatic events Shelter and human settlements Population displacement and migration The challenge of poverty and inequality (MDGs) Costello A et al.
