Tropical cities face rising urban heat risks amid limited cooling infrastructure

Mongabay reports that heat risks are increasing in tropical cities facing poverty, rapid urbanization and inadequate cooling infrastructure.

Urban heat islands are described as a growing global health threat, with risks surging in tropical cities, according to Mongabay.

The report says these cities already face hot, humid equatorial weather, global warming, intense poverty, rapid urbanization and a lack of cooling infrastructure. It also says city officials face a powerful 2026–2027 El Niño that could put millions of vulnerable urban residents at risk.
