The heatwave in the Southwest is so bad that American Airlines had to cancel 50 flights.
An intense heat wave is crippling the West this week – sending the mercury above 120 degrees in places like Phoenix.
In a sign of just how hot things are getting some airlines have had to cancel flights because of the heat.
American Airlines said it cancelled 50 flights out of Phoenix Sky Harbor aboard Bombardier CRJ aircraft on Tuesday because the planes can’t operate above 118 degrees.
Heat waves are intimately tied to climate change as rising background temperatures make them more intense and common.
The latest batch of heat will cook an area from northern California to western Texas – a region home to some seven of the 10 fastest-warming cities in the country.
