So far in 2013 there have been at least twenty deaths of children unattended in vehicles; 
ten which has been confirmed as heatstroke and ten which, based upon the known circumstances, are most likely heatstroke. These incidents can occur on days with relatively mild (~ 70 degrees F) temperatures and that vehicles can reach life-threatening temperatures very rapidly.
Average elapsed time and temperature rise
- 10 minutes ~ 19 deg F
- 20 minutes ~ 29 deg F
- 30 minutes ~ 34 deg F
- 60 minutes ~ 43 deg F
- 1 to 2 hours ~ 45-50 deg F
- “Cracking” the windows had little effect
- Vehicle interior color probably biggest factor
Parents and other caregivers need to be educated that a vehicle is not a babysitter or play area … but it can easily become tragedy!
