I was living in Scottsdale, Arizona in 1980, and working in Tempe on the other side of the Salt River. Three months of record rainfall caused the river to get larger than the Mississippi. Nine of ten bridges across the Salt River washed out, and turned my five minute commute into a two hour commute. Massive flooding occurred all over Arizona, Utah and California. A tornado ripped the roof off the Fresno airport. Many people died when the I-17 bridge across the Auga Fria River collapsed.
CO2 was well below Hansen’s safe 350 PPM. Politicians weren’t stupid enough at that time to try to fix the weather by forcing people to buy golf carts.
