  1. Climate Change and Public Health Concerns in North America Kristie L. Ebi, Ph.D., MPH North America 2030: An Environmental Outlook 25 June 2008

  2. Pathways by Which Climate Change May Affect Human Health IPCC 2007

  3. Health Impacts Depend on Multiple Factors • Geographic factors: • Baseline climate • Abundance of natural resources (i.e. soil, fresh water supplies) • Elevation • Biological sensitivity: • Developmental stage • Pre-existing medical conditions and/or acquired factors (i.e. immunity) • Genetic factors • Socioeconomic factors: • May increase likelihood of exposure to harmful agents/high risk residences • Associated with underlying diseases that mediate risk • Affect ability to adapt or respond

  9. Temperature and Enteric Disease RR of Salmonellaincreased by 1.2% per degree above - 10˚C RR of Campylobacter increased by 2.2% (4.5% in Newfoundland) per degree above - 10˚C RR of E. coli increased by 6.0% per degree above - 10˚C Fleury et al. 2006

  10. EDF/George Mason/NACCHO Survey of Public Health Directors Department Has Expertise to Assess Health Risks?

  11. Priority Issues to Address • Increase resilience of public health systems • Uniform data indicators and data systems • Decision support tools for climate change and health • Explicitly incorporate climate change into transboundary cooperation for: • Air toxics • Vectorborne diseases • Health impact assessments of mitigation and adaptation programs and activities across all sectors
