Saguaro Nat Park Got So Hot Last Week Rangers Baked Cookies In a CarSeems like with the worsening of climate change, we’re awash in terms for weather events that previously would have just been called “hot,” “cold,” or “wet.” For example, last week’s “heat dome” that sent temperatures soaring over the Southwest. That’s not a new meteorological term but it wasn’t one that was regularly on people’s lips. Anyway, that heat dome sent temps so high, rangers in Saguaro National Park, near Tucson, Arizona, showed just how hot the inside of a car can get on a scorcher by baking a tray of cookies on a car’s dashboard. But literal baking in a car is a new one for us. As always, never, ever leave animals or people in a car on a hot day, but do leave cookie dough if the dash is hot enough.
