LA Heat Risks in a Warming World
Abstract:
<p dir="ltr">The Urban Heat Island (UHI) effect is a growing concern as heat waves intensify, particularly in densely populated urban areas like Los Angeles (LA). This phenomenon causes significant elevated temperatures within cities compared to its surrounding rural areas. In Los Angeles, factors such as prevalence of heat absorbing surfaces, the removal of vegetation, and air pollution all play a significant role on UHI. The UHI effect in Los Angeles has significant implications for public health, often associated with heat-related illnesses, cardiovascular issues, respiratory problems, and risks during pregnancy, especially with vulnerable populations like the elderly and children. As the relationship between health and heat continues to deepen, it is necessary to identify which regions in Los Angeles will be the most impacted. Using GIS technologies we can plot the most significant factors of UHI as health data to understand more about the groups who are experiencing the brunt of the effect. All data was sourced directly from the City of Los Angeles, CalEPA’s Urban Heat Island Index and the California Healthy Places Index. We found there to be a correlation between median household income and heat related health illnesses. However, more research must be done on other factors such as the UHI during different times of day (late nights, early mornings) as well as seasons (winter vs. summer). We hope to display our findings in a public dashboard that can be used by non-profit organizations and other agencies when prioritizing where to distribute resources during extreme heat events.</p>
