Public Health Impacts of Climate Change in Washington State: Projected Mortality Risks Due to Heat Events and Air Pollution

As a subset of the state's 2009 Climate Change Impact Assessment, this chapter is focused on two key public health concerns related to climate change: heat-related illness and worsening air quality. This study had three goals: 1) to determine the historical relationship between extreme heat events and mortality in different regions of Washington State, for selected age groups and causes of death, 2) to use these findings to predict the number of excess deaths by age group and cause during projected heat events in years 2025, 2045 and 2085, and 3) to use estimates of the relationship between ozone concentration and mortality available from the scientific literature to predict the number of excess deaths in mid-century (2045-2054) due to ozone under a changing climate, assuming a growing population. The report integrates estimates of ozone concentration and mortality to provide an initial quantitative assessment of potential mortality impacts in the mid 21st century. Specifically, it estimates the excess mortality due to climate-related ambient ozone concentrations in Spokane County and King County, Washington for the recent decade (1997-2006) and mid century decade (2045-2055).
