Airline passengers might need to brace for more turbulence, as climate change increases severe weather

A few incidents this past year have highlighted one kind of unpleasant experience some end up having on airplanes: turbulence. And these kinds of incidents like that might be getting more common, a union representing flight attendants is warning — thanks to climate change. 

In December, 36 people were hurt and 20 were hospitalized, with 11 sustaining serious injuries, when a Hawaiian Airlines flight from Phoenix to Honolulu experienced "severe turbulence," officials said.

Eight people were hospitalized after an American Airlines flight from Tampa, Florida, to Nashville, Tennessee, experienced severe "unexpected turbulence" and was forced to land in Alabama, a spokesperson for Birmingham's airport told CBS News.
