A major heat wave is occurring across the western USA and a new report claims that will become more common in coming years.

And it goes without saying that people with respiratory issues should avoid going outside when the temperatures are so high due to the poor air quality during a heat wave. A lot more.

Kurt Dickson, an emergency room doctor at Banner Health in Phoenix, said people have a range of heat illnesses during the summer months, including fatigue, heatstroke and severe sun burns.

Extreme heat can also affect planes, because the hotter it is, the thinner the air gets. Tuesday's afternoon temperatures are expected to reach 120 degrees, meaning that those planes won't be able to take off or land at Sky Harbor.
