 HEAT-RELATED ILLNESSES ARE CLIMBING. CBS'S ELISE PRESTON IS IN LOS ANGELES. IN SCORCH, IN CALIFORNIA, FIRST RESPONDERS LIKE JULIE WHITNEY ARE WORKING 72-HOUR SHIPS DEALING WITH A SPIKE IN CALLS FOR HEAT-RELATED ILLNESSES. IS THERE ANYTHING SURPRISING TO YOU ABOUT THE HEAT THIS SUMMER? I FEEL LIKE IT CAME ON A LOT FASTER. PARAMEDICS WARN THE HEAT IS SO INTENSE IT ONLY TAKES ABOUT 15 MINUTES OUTSIDE BEFORE YOU COULD START TO FEEL SICK WITH DIZINESS, CRAMPS OR NAUSEA.
