Turbulence and Its Rare Death Toll
Deaths are a striking anomaly. The BBC reported on Thursday (July 30th) that fatalities caused by turbulence are extraordinarily uncommon. Official statistics are absent, yet estimations suggest that perhaps four individuals have died since 1981.
Injuries Are a Distinct Count
In the United States alone, 207 people have sustained severe injuries amid turbulent episodes since 2009. The National Transportation Safety Board has verified this figure.
- Cabin crew are most at risk. Of those injured, 166 were airline staff.

Climate Change Amplifies Air Turbulence, Experts Warn
The most recent findings suggest that increasing temperatures are intensifying turbulence in the upper atmosphere. Scientists caution that this trend could exacerbate as warming continues and upper‑level wind patterns exacerbate in frequency and strength.
Key Points
- Upper atmosphere turbulence is now linked to rising global temperatures.
- Experts predict that turbulence could worsen as the climate shifts.
- Increased wind pattern frequency and intensity could lead to more disruptive flight conditions.
Implications for Aviation
As turbulence intensifies, airports and airlines will face heightened operational risks. The aviation sector may need to adapt flight plans and modify aircraft design to mitigate the impacts.
Moving Forward
Ongoing research is essential to understand the complex relationship between climate change and turbulence, guiding effective strategies for the aviation industry.
Doubling and tripling of severe turbulence
Projected Surge in Severe Turbulence Due to Climate Change
Professor Paul Williams, an atmospheric scientist at the University of Reading, warned the BBC that the frequency of severe turbulence could double or even triple in the coming decades.
Key Facts
- There are roughly 5,000 incidents of severe or greater turbulence reported annually worldwide.
- More than 35 million flights take off each year.
- In 2023, turbulence accounted for 40 % of all passenger injuries, according to the International Civil Aviation Organisation.
- Since 1985, the North Atlantic has seen a 55 % increase in severe turbulence on routes between the UK, the US, Canada and the Caribbean.
Williams explained that climate change is warming the air south of the jet stream more than north, amplifying the temperature difference and driving a stronger jet stream, which in turn raises the intensity of turbulence.
Implications for Aviation
The anticipated rise in severe turbulence could extend periods of turbulence from 10 minutes to 20–30 minutes per flight segment, indicating a higher risk for aircraft and passengers.
Perhaps more injuries, and also more seatbelt time
Climate Change Is Making Air Travel Rougher
The Federal Aviation Administration (FAA) recently issued a statement clarifying that turbulence is a normal, frequent motion of air that can affect an aircraft. It often happens unexpectedly and without warning, caused by atmospheric pressure, jet streams, cold or warm fronts, and thunderstorms. Turbulence can even occur when the sky appears completely clear.
Evidence of Increasing Turbulence
- In 2023 the American Geophysical Union (AGU) published a report indicating that modern skies are 55 % bumpier than they were 40 years ago.
- “The rises in turbulence are consistent with the effects of climate change,” the AGU added in a separate study, noting that warmer air resulting from carbon‑dioxide emissions is intensifying wind shear in jet streams, strengthening clear‑air turbulence in the North Atlantic and worldwide.
Implications for Passengers
Although turbulence has become more frequent and sometimes more intense, the AGU stressed that these changes are not inherently more dangerous or the primary driver of passenger injuries.
Expert Perspective
Captain Nathan Davies, a commercial airline pilot, summed up the situation: “It’s generally nothing more than annoying,” he said. “However, it might mean more time sitting down, with the seatbelt fastened.”
Even if turbulence becomes more frequent and severe, experts argue that passengers can travel safely, with only minor inconveniences.
