No. California statewide annual precipitation has shown no radical long-term change over the past 75 years. NOAA records indicate high year-to-year variability (extremes from under 8 to over 40 inches) but no significant overall trend in totals, which average near 22-23 inches. Periods of wetter or drier conditions occur within historical ranges.
