 About 130 million people are under heat advisories and tomorrow could hit 130 degrees in Death Valley. If it officially does, that'll be the hottest temperature ever reliably recorded on Earth. Park rangers warn visitors to stay away when it's that hot, but they flock to Death Valley to experience it and get a photo with a giant thermometer. The rangers have told us you're on your own. We will not do a search on foot for those people until it cools down below 120 degrees.
