In a world getting used to extreme weather, 2023 is starting out more bonkers than ever and meteorologists are saying it’s natural weather weirdness with a bit of help from human-caused climate change. Much of what’s causing problems worldwide is coming out of a roiling Pacific Ocean, transported by a wavy jet stream, experts said.
After the driest start to any year on record, California will end 2022 with snow-capped mountains, soaked roadways and — in some places — flood warnings. The soggy end to an otherwise bone-dry year came as something of a surprise. Only weeks earlier, officials sounded the alarm about a rare third appearance of La Niña — a climate pattern in the tropical Pacific that is often associated with dry conditions in the state.
Some western residents are breathing a sigh of relief after recent atmospheric river storms have drenched the drought-parched region, and more are on the way. However, scientists caution that it is too early to celebrate. “At this point in time, we still have another four or five months in our snow season and in our typical rainy season,” said Andrew Schwartz, lead scientist at the Central Sierra Snow Lab.
People don’t eat much alfalfa, at least not directly. But the crop widely grown throughout California and the West to feed cows across the world has become central to discussions about managing a future with limited water. That’s part of the larger debate over what’s being grown and where it goes, and even what people should eat to ease pressure on the water supply and fight climate change.
California made historic investments in climate measures this year, as state leaders warned of current and escalating climate risks. “We’re dealing with such extremes that all our modeling, even updated modeling, needs to be thrown out,” said Gov. Gavin Newsom when he signed more than 40 bills to fight climate change in September. “The hots are just so much hotter. The dries are so much drier.”
Here we are nearing the end of another year. And the SJV Water team has been taking stock, reflecting and pondering the accumulation of news and events that made up 2022. (Really, we’re taking some much needed time off and I’m, personally, “checkin’ the snow pack” – code for skiing – and needed to stockpile some content. SHHH!)
Atmospheric rivers can wreak havoc on the West Coast. These “rivers in the sky” stream enormous amounts of moisture from the tropics to western North America — double the flow of the Amazon River, on average. This moisture can produce downpours that cause widespread flood damage. From 1978 to 2017, this damage amounted to $1.1 billion per year according to a 2022 study. But atmospheric rivers are also crucial for life in California.
When it comes to the view of desalination as a tool to drought-proof local water systems in California, 2022 has been a roller-coaster year. In May, the California Coastal Commission, a 12-member appointed board responsible for overseeing the state’s 1,100 miles of coastline, rejected on environmental grounds a $1.4 billion desalination facility proposed for Huntington Beach.
With climate change and drought, the state of California is incentivizing not using farmland or fallowing it. The move comes as irrigation in some areas is damaging residential wells. Katie Staack farms 3,500 acres of almonds in Stanislaus County. She is one of the hundreds interested in the newly created LandFlex program. “The program is really unique because it’s focused on wet water, making sure we have wet water for our communities and aquifers, our ecosystems and farms,” Aubrey Bettencourt said.
As California is preparing for their fourth year of drought, the Bureau of Reclamation warns Central Valley Project water contractors of lessened water allocations. Two months after the start of the new water year on Oct. 1, the Shasta Reservoir, the state’s largest reservoir and cornerstone of the Central Valley Project (CVP), is currently at 31% capacity.
