FORT WORTH, Texas — Over the next 30 years, Texas and other parts of the central U.S. are at risk of being exposed to extreme heat — temperatures exceeding 125 degrees. The human body can no longer tolerate heat at these levels. A study published in 2010 estimated that a wet-bulb temperature of 95 degrees Fahrenheit at 100% humidity, or 115 degrees at 50% humidity, would be the upper limit of safety, beyond which the human body can no longer cool itself by evaporating sweat from the surface of the body to maintain a stable body core temperature. Another way to calculate how dangerous the heat ...
