"Homogenizing" the Way to Global Warming

Less than a decade ago I found some NOAA temperature charts for nearby cities in Northern California - where I've lived off and on since 1949. The cities are Santa Rosa and Ukiah, and  i remember old timers in the 1950s talking about how much hotter they had been in the 1930s and 1940s. The NOIAA temperature charts substantiated the old timers' memories - for awhile.

This was the Santa Rosa chart showing the hotter 1930s and 1940s:
This is the Santa Rosa chart that replaced it after "homogenization." The early years suffered a cold snap that lowered temperatures about one degree C for four decades and then raised later temperatures gradually.
How about Ukiah? Not surprisingly, Ukiah also found that its cooling trend became warming.

Before homogenization:
After homogenization.
It's funny that after over half a century since they passed on, the old timers were made liars about their memories of the hotter olden days.
