dust storm

Last month, dust storms in Texas and Kansas reduced visibility on roads, resulting in multi-car pileups that killed at least 11 people. "Wind is unlike many other hazards because you really can't see it," says AAA's Bill Van Tassel.

"The scale of devastation across our state is staggering," Missouri Gov. Mike Kehoe said. "While we grieve the lives of those lost, we are also focused on action."

A rare dust storm in Illinois this month caused a 72-car pileup on an interstate. Climate experts say it points to a bigger problem — soil erosion.
