Thank you, Dan. One dad's response to the Georgia toddler left to die in a hot car. He's trying to raise awareness to show what happens in a sweltering vehicle. Linsey Davis has the story. It's 86 to 90 degrees outside. And I'm sitting in the car with the windows rolled up. Reporter: It all started with one dad so outraged by another father's actions, he issued what he called a hot car challenge to parents around the world. I want to know how it feels to be left in the car. And, sitting in the backseat, strapped into a car seat with the windows up. Reporter: His name is terry Bartley, a father of three from North Carolina. I was losing air. Hot, stuffy. Like I was hitting in the micro wave. Reporter: He was hot rate issued to make the video after he saw news koemg coverage of 22-month-old cooper Harris's death. Children being left in hot dars. A 5-year-old boy found dead inside a car. Reporter: At least 17 children have died in hot cars this year alone. Bartley is hoping his hot car challenge will raise awareness. There's a lot of people out there that felt similar to the way I felt. Reporter: Since posting his video at the end of last month, it's been viewed more than a million times, inspiring toers take the challenge. We got the dog if the car. Look how bad she's panting. Please don't let your children and animals stay in the car for any reason. Reporter: Parents across the country joining forces, saying enough is enough. It only takes about 10 to 20 men Ou minutes for a car to heat up to deadly temperatures. The man who started this, said he could only last for about 1 minutes. Children are not able to withstand the heat as much as adults. Hope the campaign can make a difference.
