New research shows that climate change will make flights longer due to faster jet stream winds. The jet stream is a high-altitude wind that blows from west to east across the Atlantic Ocean; when jets travel from the U.S. to Europe, that jet stream helps get them there more quickly, but on the return journey, those winds increase the flight time by about an hour, currently. The study, done by Dr. Paul Williams in the UK, looked at climate models and combined them with the software used by aviation companies that calculates the best routes each day to show how warming will affect the flight times. The results showed that each eastbound flight will be lengthened by one minute and 18 seconds each, totally 2,000 extra hours per year for all transatlantic flights.
