California Gov. Jerry Brown has made some of the state’s temporary water restrictions permanent. The executive order issued Monday the 9th of May, in response to the state’s drought, permanently bans wasteful practices like hosing sidewalks and washing cars with hoses that don’t have shut-off nozzles.
“Californians stepped up during this drought and saved more water than ever before,” Brown said in a statement. “But now we know that drought is becoming a regular occurrence and water conservation must be a part of our everyday life.”

I am in agreement with Gov Brown that we need to save every acre-foot of water that is humanly possible, but I disagree him on the driving reason. Governor Brown is promoting climate change in his executive order, and the drought is a natural cycle.
We can expect the drought to continue as a strong El Niño fades and is replaced by a deepening La Niña. It has been that way for millions of years, long before anthropogenic climate change was created and promoted by progressives seeking wealth redistribution from rich capitalist nations to poor socialist nations. Study this chart:
The Pacific Decadal Oscillation is in a negative phase, with the emergence of a La Niña pattern. Historically this has produced an extended dry climate over the Southwest US, including California. PDO phases last 20-30 years.
The La Niña/El Niño pattern oscillates on a 2-year to 7-year cycle. However, during past periods in climate history a La Niña pattern has lasted for 200 to 500 years. It could again with a forecast of a diminished sunspot cycle.
Diminished solar cycles have been associated with the Maunder Minimum from 1645 to 1715 and the Little Ice Age from 1300 to 1870, with the coldest periods between 1600 and 1800. There is evidence that the Sun has had similar periods of inactivity in the more distant past. However, the connection between solar activity and terrestrial climate is still an area of on-going research.
There is a higher probability this California will be cool and dry, then hot and dry. Either way, we can expect drought conditions for sustained periods, with some periodic El Niño rains. The real question is how many years apart will those rainy spells be? In the early 1800s, one dry period lasted 13 years. In the 1100s, it was 27 years.
Bottomline, regardless of the cause climate change or natural cycles we are in for more drought, plan accordingly.
