Here’s some news that could literally shake up air travelers, particularly if you’re a frequent flyer. More severe midair turbulence caused by climate change is making air travel more dangerous for flight attendants and passengers alike, according to this article from Vox. For flight attendants, who are often working in the aisles, these worsening incidents pose serious occupational risks. Turbulence is already costing U.S. airlines $200 million per year, with damage to aircraft plus injuries to passengers and crew. A study by a leading atmospheric scientist indicates that dangerous clear air turbulence is expected to more than double by midcentury, and that turbulence “strong enough to catapult unbuckled passengers and crew around the aircraft cabin” is expected to double or triple.
