EGU 2013: a bumpy ride for transatlantic flights

By Liz Kalaugher

If, like me, you’re a nervous air passenger, the news from today’s European Geosciences Union General Assembly wasn’t good. Speaking at a press conference just 15 minutes after the publication of his paper, Paul Williams of the University of Reading, UK, revealed how climate change is likely to bring stronger and more widespread clear air turbulence for transatlantic flights.

A doubling of carbon-dioxide concentrations, which could well occur by the 2050s, would increase the average strength of clear air turbulence by 10–40%, Williams and colleague Manoj Joshi of the University of East Anglia, UK, calculated. The amount of airspace containing significant turbulence would also increase by 40–170%; Williams said the most likely figure would be 100%.
