Why airplanes may carry fewer passengers due to global warming

British researchers from the University of Reading examined numerous European airports and concluded that rising temperatures may force airports to reduce passenger numbers. Warmer air is less dense, making it harder for planes to generate lift. The study, published in Aerospace, focused on the Airbus A320, a commonly used passenger aircraft in Europe. By 2060, airports with shorter runways may need to reduce maximum weight by an amount equivalent to about ten passengers per flight during summer months.

Lead researcher Dr. Jonny Williams explained that hotter summer days will become more frequent, increasing operational challenges. Southern European tourist destinations like Chios (Greece), Pantelleria and Rome Ciampino (Italy), and San Sebastian (Spain) are particularly affected due to their shorter runways. Larger airports like London Heathrow and Schiphol may face issues with bigger aircraft like the A380.

The solution? Reduce CO2 emissions to slow global warming and ensure planes can continue operating efficiently.
