The Deadly Threshold: The Unbearable Heat for Human Survival
Scientists have determined that the maximum mix of heat and humidity a human body can survive is around 35 degrees Celsius (95 Fahrenheit) when coupled with 100 percent humidity. This critical limit, known as the "wet bulb temperature," has been breached only a few times and has never resulted in mass mortality events. However, as global temperatures rise due to climate change, dangerous wet bulb events are expected to become more common. Last summer, over 61,000 people died in Europe due to heat-related causes. The most vulnerable to extreme heat are children, the elderly, and those who work outside in high temperatures.
