Our planet's rising temperatures are making it harder for planes to take off at certain airports, presenting yet another challenge to civil aviation. And as heatwaves become more frequent, the problem could extend to more flights, forcing airlines to leave passengers on the ground.

'Global stilling'Williams and his team researched historical data from 10 Greece airports, all of which were characterized by high summer temperatures and short runways. They found a warming of 1.35 degrees Fahrenheit per decade since the 1970s.

In 2017, dozens of flights were canceled entirely over a few days at Phoenix's Sky Harbor International airport as temperatures reached 120 degrees Fahrenheit , which is above the maximum operating temperature for many passenger planes. In the meantime, manufacturers like Boeing are already offering a"hot and high" option on some of their aircraft, for airlines planning to use them extensively in high-altitude, high-temperature airports. The option provides extra thrust and larger aerodynamic surfaces to make up for the loss of lift, with no change to range or passenger capacity.
