More than 100 people have died in devastating flash floods in Kerr County, Texas. But what caused this extreme weather, and will events like this get more common?

Flash floods in Texas have killed more than 100 people, many of them children. Heavy rains fell quickly in the predawn hours Friday in the Texas Hill Country.
