Unraveling the Turbulence: How Climate Change is Shaking Up Our Skies

The seatbelt sign blinks, trays shake, and drinks splash. For many travelers, turbulence is a nerve-wracking experience. With climate change, it’s becoming more common and intense.

Why Turbulence is Important

Turbulence isn’t just uncomfortable; it’s also the main cause of in-flight injuries. Between 2009 and 2024, there were 207 reported injuries on U.S. commercial flights, according to official data. High-profile incidents have caught the public’s attention, like an Air Europa flight where 40 passengers were injured.

John Abraham, a mechanical engineering professor, states, “Modern planes can handle turbulence. The real danger is unbelted passengers.” Planes do need inspections after severe turbulence, a scenario that occurs about 5,000 times a year in the U.S.

How Climate Change Intensifies Turbulence

Mohamed Foudad, an atmospheric scientist, identifies three types of turbulence: convective, mountain wave, and clear-air turbulence (CAT). Convective turbulence is usually linked to thunderstorms and can be detected with radar. Mountain wave turbulence happens over large terrain. CAT is dangerous because it’s invisible and often generated by jet streams.

Recent research shows that as the tropics warm faster than higher latitudes, jet streams become more erratic. This creates more wind shear, which can lead to increased CAT. A study published in the Journal of Geophysical Research: Atmospheres revealed a significant rise in turbulence frequency globally, from 60% to 155% in various regions.

What’s Next?

A 2023 study indicates that for every degree Celsius of warming, moderate CAT incidents may jump by 9% in winter and 14% in summer in the North Atlantic. Climate change is also likely to lead to stronger storms, increasing turbulence around thunderstorms—historically a major factor in turbulence accidents.

To address these challenges, Foudad is developing strategies to optimize flight routes. Airlines are advised to keep passengers buckled up more frequently. Technologies such as onboard LIDAR are being tested to detect air density shifts before they reach passengers.

Reducing greenhouse gas emissions remains essential. The aviation sector is responsible for about 3.5% of human-caused warming. Efforts to find cleaner fuels are underway, though progress has been slow, as noted by the International Air Transport Association.

Understanding these dynamics helps us better prepare for future flights. As climate change continues to shape our weather patterns, staying informed can lead to safer, more comfortable journeys.
