Climate Change and Human Health

From heat waves to floods, from poor air quality to the spread of vector-borne disease like Zika, many climate hazards translate directly into measurable adverse effects on human health. At Four Twenty Seven, we have been working hard to both create and gather the best resources and tools designed to help the healthcare sector plan for the impacts of climate change.


Heat and Social Inequity in the United States

Heat and Social Inequity in the United StatesFour Twenty Seven has developed a series of maps that examines one of the most significant public health risks posed by climate change: heat vulnerability. These maps combine projections from global climate models with socioeconomic indicators of heat vulnerability to compare the complex and interconnected components of heat risk and resilience by county in the U.S.


California Heat & Health Project

CHATAs part of California’s Fourth Climate Change Assessment, Four Twenty Seven is working with project partners to develop an interactive tool that will inform long-term planning efforts to communicate the urgency of and mitigate the public health impacts of extreme heat across the state. We released a report on the literature review and user needs assessment performed to understand how the tool should be designed to improve efforts most effectively in all California regions.


San Francisco Flood Vulnerability

San Francisco Flood Vulnerability In San Francisco, local flood inundation coupled with extreme storms is projected to have a direct impact on health outcomes in the city. The most likely health impacts related to flood include physical injuries, waterborne illnesses, respiratory illnesses, vector-borne disease, and food-borne illnesses. Our interactive story map illustrates how flood inundation and extreme storms may affect public health, with a specific focus on vulnerable communities.


India Heat Impact Project

India Heat Impact ProjectUsing high-resolution climate models to explore the impact of rising temperatures on human health and labor productivity. India, with relatively low GDP per capita, high population density, and tropical climate, is particularly vulnerable to these effects. This project presents the challenges through an interactive story map, exploring the impacts of heat and humidity, and emerging practices in adaptation planning.


Resilient Hospitals Dashboard

Resilient Hospitals DashboardA busy medical ward is the last place you want the lights to go out in the event of a hurricane, flood or extreme weather event. These same conditions can drive surges of patients that can outpace the hospitals’ capacity to react. However, most hospitals have yet to integrate local climate change projections into their risk management and planning processes. Our team has created the Resilient Hospital Dashboard, an application designed to help hospitals understand their vulnerability and enable uninterrupted patient care.
