If that ice storm had hit Southern California, there would have been 20 million without power. Same thing if it had hit Arizona. The sun belt is not prepared for massive ice storms
The all time low in downtown Los Angeles was 26 degrees in 1949. At LAX it hit 23 in 1937. Burbank recorded 22 in 1979. In Lancaster it got down to 2 degrees in 1984. Don’t know for sure but there’s was likely very little or no snow. If an ice storm like this hit Southern California then climate change is real and it wouldn’t be getting warmer.
