Sierra snowpack down to 12% of normal.
Climate change predicts a drier California & southwest.
"Climate change" (whatever entity you're referring to) predicted many things that didn't pan out.
The Southwest's temperature from 1895-2013 is below. As you can see it was hardly consistent with a gradual build up of CO2. Temperatures int he Southwestern U.S. instead reflect the modes of the Pacific Decadal and Atlantic Multidecadal Oscillations, seeing a rapid cooling after a very warm late 19th century to a relatively cold 1910s/20s.
You see a cold period in the 1960s/early 70s as well... with warm periods in the 1890s, 1940s, 1950s, then rapid warming in the 80s and 90s.. with what appears to have been another peak in the early-mid 2000s and falling temps once again.
This jives with the PDO and also with solar activity. The 1910s and 20s and also 1960s and early '70s were the periods of lowest solar activity in the 20th century with the highest levels in the late 80s to early 2000s and also the 1940s and 50s.
