In places like Baton Rouge, Louisiana, rising heat is driving an uptick in exposure rates, as the population remains relatively static.
Cities with stable populations like Baghdad, Cairo, and Mumbai have also seen an uptick in heat exposure driven by rising temperatures.

The trend toward urbanization could be making climate change even more dangerous, the study shows.
The authors say urban planners can use the data to build cooling into cities — by planting more trees or using less heat-trapping materials — and mitigate the heat island effect.
Even with smarter heat management, climate change and urbanization are not slowing down. As the 2021 United Nations climate report shows, slowing climate change will take a lot more than one city’s actions.
