As the new year begins, California’s Sierra is closing in on the second-largest snowpack we’ve seen at this time of year in the last two decades, with more snow expected to pummel the mountain range in the coming days. But here’s why it’s far too soon to declare an end to the drought: Last year, we started 2022 with a similar bounty — and then ended the snow season way, way, way below normal.
She’s baaaack! For the past two years, La Niña, the cooling of ocean temperatures in the equatorial Pacific, has wreaked havoc on weather around the globe. Now the World Meteorological Organization expects the phenomenon to return for a third consecutive year, a rare occurrence that forecasters predict could bring wackier-than-usual winter weather to the West, once again.
California, particularly Northern California, was walloped by a major winter rain and snow storm last week and meteorologists expect that high levels of precipitation will continue for at least another week. Despite some damage and at least one death from local flooding and tree-toppling high winds, the storm and the predictions of more to come are welcome relief from what had appeared to be a prolonged drought.
Folsom Lake is letting the water flow while rains pick up across the valley. December has provided higher-than-average precipitation for the capital region giving way to cautious optimism about just how much longer the state will be in a drought. But the rainfall also prompted questions about why, in a drought, dams and reservoirs are letting water out instead of holding it in.
All good stories start with a question. So here are five questions for journalists to consider as the record-breaking accumulation of greenhouse gases continues into the opening days of 2023. Climate change, of course, can’t be divided into parts. The answers to these questions, however you devise them, may start small and specific and then, like climate change itself, to borrow the title of a popular 2022 film, illustrate how it is “everything everywhere all at once.”
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.
Reporters who slog through a meadow near Lake Tahoe next week for California’s first manual snow survey of the season will find copious amounts of snow. The state Department of Water Resources’ electronic readings on Dec. 29 showed a statewide snowpack at 156% of normal as a persistent parade of storm clouds has pelted the West Coast in December.
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.
The grass beneath the palm trees at the Foothills has no function other than to look lush and inviting for people driving up to the gated community’s entrance. The homeowners’ association there, like many that govern such developments dating to the 1980s and 1990s, was still sprinkling Colorado River water on about 50,000 square feet of turf this year.
Eight of the top 10 warmest years on record occurred in the last decade. The snowline where rain turns to powder continues to move uphill. The dry season is longer than ever as wildfires ravage forests and communities. It’s a bleak outlook for the state of the Sierra Nevada snowpack, not to mention our planet as a whole.
