🌿 Can trees cool #Calgary ?

[datastory@mstdn.ca]

Can trees cool #Calgary ? 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 #YYC microclimate suite.
