Brown/AFP via Getty Images California lawmakers are looking to institute a ranking system for heat waves, much the way weather forecasters already do for hurricanes. If implemented, it would be the first state in the country to develop rankings for extreme heat — a dangerous issue that’s only becoming worse in a warming world.
The proposed ranking system for heat waves has three levels of alerts for extreme heat, with Number One being the least dangerous and Number Three being the most dangerous, based on how hot it actually is and the potential health impacts.
