<![CDATA[🌿 Can trees cool #Calgary ?]]>🌿 Can trees cool ? Summer 2025 data from 193 neighborhoods reveals a tipping point: 0.34 NDVI.
🔹 Below 0.34: Isolated trees in "concrete jungles" provide ~0 cooling ROI.
🔹 Above 0.34: Cooling "clicks in" & efficiency jumps.
Stats: Vegetation explains 40% of heat; 60% is locked in asphalt & design. Where we can't plant, we must use high-albedo materials.
Validated by Davies test. Part of my broader microclimate suite.
