2. Vulnerability Vulnerability to climate change is “the degree to which geophysical, biological and socio-economic systems are susceptible to, and unable to cope with, adverse impacts of climate change.” (Füssel and Klein, 2006) 2

3. Community’s overall vulnerability Exposure: Changing environment due to global warming Population characteristics/Sensitivity (e.g. age, pre-existing disease) Adaptive capacity : –Community Resilience (Resources) –Response Capacity: Capacity of public health and emergency response infrastructure

4. Population Sensitivity Varies by Climate Health Threat Heat: – Elderly, Medical compromised, Social Isolation, Children, low income, occupational Flooding/Extreme events: – Elderly, low-income, homeless, disabled, lack of transportation, obese, co-morbid Drought: – dialysis patients, elderly, pregnant and nursing women, infants, immunocompromised individuals

5. Vulnerability Assessment in BRACE Statewide vulnerability data will be used to develop vulnerability indicators and maps for all census tracts in California A more detailed vulnerability assessment will be done in at least one county from each of the ten multi- county regions. Assessments will use 2000 as a baseline and we will make estimates for each decade up to 2040 and a final statewide assessment at 2099. For each assessment, we will use projected demographic data and projected climate change data (sea level rise, wildfire risk, and extreme heat days).

11. 46% of African Americans and 36% of Latinos reside in the two highest risk categories compared to 30% of whites Los Angeles County 11

12. 12 In LA County, median income in the highest risk area is 40% lower than the lowest risk area

13. Questions What LHD staff & programs / policy leaders/ partners/ stakeholders will you share this with; and how and in what context or venue will you present it; get feedback; and adapt and update it as new information is available? Will you engage vulnerable populations directly or work with partners for community -based input on the maps and report? 13
