/r/collapse (is it unpopular to mention here?) has been discussing wet bulb events for years. They are occurring with increasing frequency and are very hard to survive without air conditioning or an underground shelter (e.g. cool cave). But A/C uses large amounts of energy, which not only strains the power grid but also increases CO2 emissions, which causes more extreme wet bulb events...
