Using the Berkeley Earth Surface Temperature (BEST) data here, the following plot was created. It represents local climate change for lattitude 34.56 N, longitude 118.70 W, with nearby cities of Los Angeles, Glendale, Oxnard, Santa Clarita, Pomona, and Torrance. The plot shows the mean monthly surface temperature, the 95% upper confidence levels for the daily high temperature, and the 95% lower confidence levels for the daily low temperature. Compare the plot below with that proivided here based on the same underlying data.
