A pair of college students. A nurse and musician. A 4-year-old strapped into her car seat.
In one horrific accident after another, these four and at least 71 others lost their lives last year when vehicles they were in flooded or fell when roads and bridges collapsed. 
Vehicle-related flood deaths reached a five-year high in 2021, in part because of extreme rainfall that scientists expect to grow worse as the climate warms.
