Phoenix is the second-fastest warming city in the USA over the past 50 years while Las Vegas comes in at third and Tucson at seventh.

In addition to grounding flights of smaller planes, airlines have been taking other measures on larger jets to reduce their weight because of the heat. Sweat makes your skin feel cooler and some heat is removed as it evaporates.
