California Building Resilience Against Climate Effects (CalBRACE)

Climate Change and Health Vulnerability Indicators for California

Indicators, data and narratives to assess exposures, social vulnerability and adaptive capacity

Background

The CalBRACE Project developed climate change and health indicators narratives and data to provide local health departments and partners tools to better understand the people and places in their jurisdictions that are more susceptible to adverse health impacts associated with climate change, specifically extreme heat, wildfire, sea level rise, drought, and poor air quality. The assessment data can be used to screen and prioritize where to focus deeper analysis and plan for public health actions to increase resilience.


The CalBRACE project was partially supported by the Centers for Disease Control and Prevention (CDC) Climate Ready States and Cities Initiative (CRSCI) through Cooperative Agreement 5UE1EH001052. The contents are solely the responsibility of the authors and do not necessarily represent the official views of CDC or the US Health and Human Services Agency.


CalBRACE Vulnerability Assessment Framework

Vulnerability assessments are a key tool to begin to prepare and plan for resilience to climate change and health impacts. A climate change and health vulnerability assessment helps to identify where a person’s or neighborhood’s susceptibilities to injury or disease exist due to their distance and sensitivity to climate-related environmental exposures or hazards. Adaptive capacity can offset the potential for injury and disease from exposure and sensitivity to hazards associated with climate change. Understanding more about neighborhoods and populations with multiple or complex social vulnerabilities can improve prioritization of efforts, inclusive planning, communication, and evaluation of adaptation and interventions developed to protect communities from the effects of climate change. The suite of domains and indicators developed by the CalBRACE Project is focused on assessing current and future climate change exposures (such as wildfires, extreme heat, air pollution, sea level rise, and drought), the people and places most susceptible to health risks from climate exposures, and the capacity to adapt to a changing climate. Also see: The CalBRACE Climate Change and Health Profile reports and Resources for adaptation planning for climate change and public health.

Climate Change & Health Vulnerability Data and Indicators

The CalBRACE Project produced climate change and health vulnerability indicators for download using the link below. Each indicator includes the data in an Excel file as well as a narrative in PDF format. Each narrative describes the indicator’s significance to climate change and health, the evidence that links the indicator to health outcomes, data sources, bibliographic references, methodology, and limitations that impact the interpretation of the indicator. Examples of maps, charts, and tables are also included. We invite you to download the data and narrative files and use them to create maps, charts, and tables of your own counties and communities.

The most up to date climate change data for California can be viewed and downloaded from www.cal-adapt.com.


The indicators are organized in three domains: Environmental Exposures, Population Sensitivity and Adaptive Capacity.

 

Environmental Exposures Domain

Environmental exposure refers to the magnitude, frequency, and duration of an environmental exposure or disease risk.

Data and Indicators:  Excel files with data for California, its counties, cities, towns, and census tracts (depending on availability) and narratives in PDF files for each indicator.

CalBRACE indicators were developed using the same methods used by Healthy Communities Data and Indicators Project (HCI). Please see the Users’ Tool Kit to view instructions for creating maps, graphs, tables, and explanatory texts using the indicators’ data files. Please see their Technical Information section for detailed information about indicator production and example SAS codes.
