More than 30 local, state and federal agencies were involved in the investigation. The FBI is analysing a cellphone found with the family, which investigators hope will provide more information about what unfolded on the trail that day. The deaths, Grie...

  What are Wet Bulb Temperatures? Wet bulb temperature  measures the combined effect of heat and humidity, representing the lowest temperature achievable by evaporating water into the air .  It is measured using a thermometer with a water-soaked cloth over its bulb, and it always reads lower than or equal to the dry bulb temperature. A higher wet bulb temperature indicates higher humidity, which hinders evaporation and reduces the body's ability to cool itself through sweating. This makes it a critical metric for assessing heat stress on humans and is often higher than the commonly reported heat index. Why Wet Bulb Temperatures are important Humidity and Evaporation :  The wet bulb temperature is essentially a measure of how well water can evaporate into the air. Human Cooling : Our bodies cool through the evaporation of sweat. High wet bulb temperatures mean less evaporation, making it harder to cool down and leading to dangerous heat stress.   H...
