There are dense locations near the equator where the wetbulb temperature has gone over 34-35 degrees celcius, which is higher than is survivable by healthy adults for more than a small handful of hours. These extreme events will keep getting worse, leading to heat stress, prolonged school closures, etc. Not all of these people have access to air conditioning because we're talking about countries with less than $6k GDP per capita. Eventually this will drive climate refugees.
