A quick summary of the takeaways of Vecellio et al.'s recent (October 2023) paper (https://doi.org/10.1073/pnas.2305427120) indicate that at +3.5 °C GMST we should expect high exposure to uncompensable heat stress every year primary around the Indus River Valley (India and surrounding countries) and the highly populated cities in eastern China. In North America, there is some exposure starting at +3°C but until +4 °C those exposures do not become substantial in the typical year.

Another thing noted is that urban features such as green spaces, water features, and increased shade may work where exceedance is typically nonhumid (i.e., North America, Middle East, Australia), these factors may not be as effective or even actively detrimental in more humid environments due to the added humidity.
