Urban heat and inequality
- 1.
Fictional simultaneous evening measurements in °C: urban sites 30, 32, 31; rural sites 25, 26, 27. Instruments are calibrated, but each group has only three sites. A tree-planting plan focuses on a wealthy shopping street while a low-income neighbourhood has little shade. All readings and locations are invented. Explain how daytime heat storage and later release can keep urban areas warm after sunset.

A tree-planting plan focuses on a wealthy shopping street while a low-income neighbourhood has little shade. All readings and locations are invented. Assess whether these readings prove that trees are the best heat-management strategy.
