Climate Change Means Bumpier Air Travel – New Challenge for Aviation

GLOBE-Net, April 9, 2013 – Turbulence on transatlantic flights will become more frequent and severe by 2050 as carbon dioxide emissions rise, leading to longer journey times and increased fuel consumption, British scientists say in a new study.

Turbulence can happen without warning and is caused by climate conditions such as atmospheric pressure, jet streams, cold and warm fronts or thunderstorms.

Light turbulence shakes the aircraft, but more severe episodes can injure passengers and cause structural damage to planes, costing around an estimated €115 million a year.

Turbulence will be stronger and occur more often if carbon dioxide emissions double by 2050 as the International Energy Agency forecasts, scientists at the universities of Reading and East Anglia said in the study published in the journal Nature Climate Change on Monday (8 April).

However, warming also changes the atmosphere 10 km above ground level, making it more unstable for planes, Paul Williams at the University of Reading and co-author of the report, told Reuters.

The scientists focused on the North Atlantic flight corridor – where 600 planes travel between Europe and North America each day – using computer simulations to examine the effects of climate change on conditions there.

They found that the chances of encountering significant turbulence by the middle of the century will increase by between 40% and 170%, with the most likely outcome being a doubling of airspace containing significant turbulence.

The average strength of turbulence would also increase by between 10% and 40%.

Bumpier air journeys would make flying more uncomfortable and raise the risks to passengers and crew.

Detours to avoid strong patches of turbulence would lengthen flight times, increasing fuel consumption, emissions and airport delays, which would ultimately drive up ticket prices, Williams said.

“Aviation is partly responsible for changing the climate in the first place. It is ironic that the climate looks set to exact its revenge by creating a more turbulent atmosphere for flying,” Williams said.
