Residents from the southwest to the eastern seaboard are experiencing sizzling heat.
The heat wave has shattered records in more than 20 cities -- tying or breaking all-time highs. Atlanta tied its all-time record high of 108 degrees Fahrenheit, which hadn't been recorded since 1873. And in Columbia, S.C., the residents experienced the sixth day of 100-degree weather.
