World Bank maps urban heat risks and what cities can actually do about them

The World Bank has produced a working paper that assesses where urban heat creates financial and health risks, and what interventions—from tree-planting to building design changes to cooling centers—actually reduce those risks. This shifts urban planning from treating heat as an inevitable background condition to treating it as a measurable problem with specific, costed solutions that cities can choose between.

For decades, cities have treated extreme heat as a weather problem, not a planning problem—but as global temperatures rise and urban areas trap more heat, the financial damage (infrastructure failure, healthcare costs, lost productivity) is becoming impossible to ignore; this work gives cities actual data on which interventions deliver the most risk reduction per dollar spent, which means heat mitigation might finally move from aspirational policy to actual budget allocation.
