11-Year Cooling Trajectory: Mature Preservation vs Sapling Lag
Chicago Study Finding: Mature 40-year tree canopies deliver ~4.8x the immediate cooling and evapo-transpiration leaf mass of young saplings. Replacing 1 mature oak with 5 saplings creates an 8-to-12-year cooling deficit, during which neighborhood heat-attributable mortality rises by 12–22%.
