The last time Los Angeles was this hot, Homo sapiens were just venturing out of Africa for the first time.
❗️Today, the Los Angeles basin will experience our hottest day in 125,000 years. Yesterday was the hottest day ever recorded in several cities. Left image shows 110°F readings at noon yesterday. Right image shows 110°F readings at noon today.
