Last week’s historic heatwave saw portions of the Northwest breaking all-time temperature records and gearing up for wildfire risk. The temperatures are now being attributed to an excess of 100 deaths across the region as it gears up for another week of extreme highs. The heat can feel apocalyptic, and scientists are increasingly studying the heat and humidity conditions at which some humans suddenly die, a phenomenon that is becoming increasingly common as a result of extreme weather driven by climate change. This is perhaps best illustrated in a study published last year in Science Advances, alarmingly titled "The emergence of heat and humidity too severe for human tolerance."
