(Death Valley, CA) — Sunday might have seen the hottest reliably recorded temperature in history. Death Valley, California hit 130 degrees just after 3:30 in the afternoon Pacific time. That breaks its August record and an overall mark it hasn’t set since 1931. Death Valley holds the world record high of 134 degrees set in 1913. But, modern scientists have since debated the accuracy of the equipment that was used. The hottest temperatures recorded with modern equipment read 129 degrees in Death Valley, Kuwait and Pakistan, all within the last decade. If the 130 stands, it would be a new modern record.
