Aviation Sector Prepares for Increased Weather Disruptions

The aviation industry anticipates increased operational challenges from a changing climate. Scientists and industry officials observe trends pointing towards more frequent and intense weather phenomena, which could affect flight schedules and routes.

Researchers at the University of Reading have identified a projected increase in clear-air turbulence. Paul Williams, a professor of atmospheric science at the university, stated, "We are projecting that clear-air turbulence will increase significantly all around the world." He also noted, "We have already seen significant increases over the last 40 years."

Hotter temperatures pose another challenge. Heat reduces air density, requiring aircraft to use more runway for takeoff or carry less fuel and cargo. Pilots may need to adjust flight paths to avoid severe weather. Mark Van Lohuizen, a meteorologist and senior consultant at To70, an aviation consultancy, explained that pilots already divert around dangerous weather. He added, "Storms are becoming more frequent and more intense. The weather will just be more extreme in the future."

Delays and diversions already cost the aviation industry millions annually. A 2023 Eurocontrol report indicated that climate change could increase air traffic management delays by 5 to 20% by 2050, resulting in an additional 4 to 12.5 million minutes of delay per year. Graham Kelly, a former EasyJet chief operations officer, remarked, "We are heading for a scenario that is worse than what we have today." He suggested that airports might need to expand their capacity to handle diversions.

While airlines are exploring options like sustainable aviation fuels and carbon capture technologies to reduce emissions, these solutions do not immediately mitigate the operational impacts of current climate trends. Van Lohuizen emphasized the need for a realistic approach: "The discussion should be, how are we going to deal with this?" Kelly highlighted the operational realities for travelers: "Passengers are going to have to accept there will be more delays and diversions."
