As temperatures took a turn for the sweltering last week, California Gov. Gavin Newsom signed a package of bills intended to protect state residents from extreme heat. First up was AB 1643, from possible future Assembly speaker Robert Rivas, D-Salinas. It creates an advisory committee to study the effects of extreme heat on workers, businesses and the economy. Then there was AB 2238 from Assemblywoman Luz Rivas, D-Arleta, to create a heat warning and ranking system akin to the one used for measuring hurricanes.
