Climate change is making plane turbulence worse, and it could make flights bumpier and more expensive

• You may experience more turbulence on future flights, especially transatlantic routes.
• Climate change has altered the jet stream and led to more unpredictable clear-air turbulence.
• For a safe flight, experts say to stay seated when the seatbelt light is on and buckle up at all times.

A Lufthansa flight that had to land shortly after takeoff is just the latest example of extreme turbulence.
