More than a month and a half into this year’s rainy season and significant precipitation was finally falling on Tuesday in Northern California. The state could use it in more ways than one.
A study last week predicts that massive, often-devastating “hundred-year storms” may occur three times as often and be 20% more severe in the U.S. due to climate change. The researchers, in a paper published in the American Geophysical Union journal Earth’s Future, found that if greenhouse gas emissions continue to increase at a rapid rate, the continental U.S. would likely see such mega-storms every 33 years.
The occurrence of historic rainfall events, like the ones that caused Hurricane Harvey in 2017 and California’s Great Flood of 1862, are likely to increase faster than lower-magnitude events, which already happen about every decade, according to UCLA climate scientist Daniel Swain.
In Crowley County, Colorado, sugar beets and alfalfa used to line the fields. It’s cantaloupes were famous.
But that all changed about three decades ago when most of the farmers sold their water rights to rapidly growing cities on the Front Range.
As the largest wildfire in Colorado history spread beyond 200,000 acres, Mark Kempton began to worry it would incinerate so much of the Fort Collins watershed that the city would be unable to guarantee water to its residents.
When the spring rains come next year, ash and debris will pour down the slopes of the Rocky Mountains and clog the city’s water intake on the Cache la Poudre River, said Kempton, interim director of Fort Collins Utilities, which oversees the water supply for Colorado’s fourth-largest city.
California is expecting its first rain of the season this weekend, a major shift in weather that’s likely to bring scattered showers and chilly breezes to the Bay Area, and freezing temperatures and snow to the Sierra.
The San Joaquin Valley has received a specially addressed message from the Union of Concerned Scientists about what it thinks people across the region should be doing about looming water shortages, worsening air quality and generally more volatile weather in the years ahead.
Tension is growing between politicians claiming to be “climate leaders”; those who say that enacted policies are too little, too late; and industry sectors lobbying to maintain the status quo. Environmental activists are pushing hard against the fossil fuel industry and commercial agriculture — two sectors that helped build Ventura County but are now being put under the spotlight for activities that contribute to global warming.
Two years ago, Cape Town, South Africa, a city of 4 million people, informed its shocked citizens that the city was just a few months away from running out of water due to drought. It was a wake-up call for all of us to become much better stewards of our own water. Luckily, for Cape Towners, innovative water conservation and efficiency measures, smarter data use, expanded water storage, and help from Mother Nature all combined to help them avoid a major water shutoff.
Global climate experts are predicting a moderate to strong La Niña weather event this year, meaning a stormy season for most parts of the world but possibly drier-than-normal conditions in Southern California. A La Niña usually means a more active Atlantic hurricane season with potentially stronger storms.
A carpet of green, new grass covered the rolling hills, southwest of Maricopa, near New Cuyama. In the distance, the coastal mountain range was capped by white, full clouds and blue sky.
