Urban Heat Island Mortality Equity: 12,000 Annual Deaths in Poor Neighborhoods From 2-4°C Temperature Differential

FixingMay 11, 2026AI: 8.0

Problem Definition

Low-income urban neighborhoods suffer 2-4°C higher temperatures than wealthy areas due to tree canopy loss and reduced green space. This creates 12,000+ excess heat deaths annually, concentrated in communities of color. Current adaptation funding flows to wealthy neighborhoods through property ownership; poor renters have no agency in cooling infrastructure.

Root Causes

Green infrastructure investment follows property value not health equity

Heat mortality invisible in policy until extreme events
