Three Provocations
1. Historic planning policies are exacerbating the local effects of climate change.
2. Local greening efforts are not centering historically underserved areas.
3. Historically underserved areas are increasingly ‘growth-permissive’ –potentially squeezing out space for expanding canopies.

Current ApproachSatellite Images
Strengths
1. Freely available for all regions of the world
2. Seasonal variability
3. Intra-urban variation in temperatures
observable
4. Extensive literature and research
5. Potential connections to land use
Weaknesses
1. Exaggerates temperature ranges
2. Coarse pixel sizes
3. Rooftops, not experiential
4. Discrete differences between land covers
5. Translation to policy remains unclear

Historians say racially restrictive covenants were typically enforced by neighborhood associations that could – and sometimes did -- file lawsuits if a home in their neighborhood was sold to a person of color. – Gibson, 2007

“HOLC maps had an economically meaningful and lasting effect on the development
of urban neighborhoods through reduced credit access and subsequent disinvestment.” –

When we…
Heed to humility, understanding historic trauma,
Empower oppressed communities,
Acknowledge existing resiliencies,
Lead with an equity lens, then we….
HEAL and build capacity to address the pernicious effects of climate change.
