This should be obvious to any parent, but let’s just document this basic truth: Never, ever leave a child alone inside a car—especially a locked car with the windows up on a hot day.
According to Dr. Dave Robinson, a New Jersey State Climatologist Professor at Rutgers University, the temperatures inside of a parked vehicle can rise 30 to 40 degrees Fahrenheit above the outside temperature in less than an hour.
This is due to the heat-trapping outcome of the greenhouse effect. When the sun’s rays pass through the windows of a vehicle, the inside of your car will absorb the energy, and with the windows up it cannot escape. Even with the windows cracked, ventilation is inadequate to prevent rapid heat accumulation.
