Playing the Index Card: Heat is the New Cold
Those in what has long been called the ‘temperate zone’ are well-schooled on the impact of wind chill, which measures how cold it feels when cold temperatures and wind are factored together. This February’s historically cold blast brought with it wind chills that broke records across the Northeast and threatened the life of anyone who ventured out without proper gear.
But while wind chill is known to most, few are as aware of the Heat Index, a measure not just of hot temperature but of how hot those temperatures feel when humidity and other conditions are factored in. The Heat Index acts as a predictor of physical impacts every bit as deadly as wind chill.
As the planet warms, and heat waves increase in frequency, duration, and intensity, the Heat Index is about to become standard protective equipment for those venturing outdoors.
