A Los Angeles Times article about the deadly consequences of extreme heat highlighted a study by the UCLA Luskin Center for Innovation. Extreme heat is becoming more frequent and severe as a result of global warming, but recent investigations show that the state has failed to address the growing threat of heat-related illness and death. The forthcoming Center for Innovation report described California’s regulation of extreme heat exposure as “fragmented across numerous state agencies” and “with no centrally responsible authority.” There are no heat exposure rules for schools, jails or prisons, and while California landlords are required to provide heating in rental units, there is no requirement for cooling. In places with heat illness prevention rules in place, such as assisted-living and childcare facilities, the extent of compliance and monitoring is unclear. Public health advocates call for coordinated statewide policies to prevent heat deaths and hospitalizations and protect those who work in hot settings.
