While Los Angeles Burns, AI Fans the Flames

As multiple wildfires tore across Los Angeles County this week, leveling thousands of homes and businesses and killing at least 10 people, incoming President Donald Trump seized upon the crisis as an opportunity to point fingers and make false claims.

“Governor Gavin Newscum [sic] refused to sign the water restoration declaration put before him that would have allowed millions of gallons of water, from excess rain and snow melt from the North, to flow daily into many parts of California,” Trump posted on Truth Social, “including the areas that are currently burning in a virtually apocalyptic way.”

No such water restoration declaration exists, but Governor Newsom’s water management policies have become a flashpoint for conservative ire after news broke Wednesday that the hydrants being used to fight the Pacific Palisades fire had run dry.

In reality, according to the Los Angeles Department of Water and Power, firefighters’ need for water at lower elevations had depleted the storage tanks, causing a drop in pressure that prevented water from traveling to hydrants uphill in the Palisades. The immense demand on the hydrants was worsened by the fact that firefighting aircraft were temporarily prevented from performing water drops amid hurricane-force winds. As local news outlet LAist put it, “water supply was too slow, not too low”; the extensive scale of the emergency meant firefighters struggled to refill the tanks quickly, not that the region lacked an overall reserve.

Trump’s latest smear campaign is little more than political football. But the renewed attention on California’s water does highlight ongoing tensions over the conservation and management of this finite resource. As the climate crisis worsens, it’s expected to exacerbate heat waves and droughts, bringing water shortages and increasingly devastating fires like those currently scorching southern California. The situation in Los Angeles is already a catastrophe. Climate change-induced water shortages will make imminent disasters even worse.

In the face of this grim reality, it’s worth revisiting one of the major water-guzzling industries that’s hastening future crises from California’s own backyard: artificial intelligence (AI).

Silicon Valley is the epicenter of the global AI boom, and hundreds of Bay Area tech companies are investing in AI development. Meanwhile, in the southern region of the state, real estate developers are rushing to build new data centers to accommodate expanded cloud computing and AI technologies. The Los Angeles Times reported in September that data center construction in Los Angeles County had reached “extraordinary levels,” increasing more than sevenfold in two years.

This technology’s environmental footprint is tremendous. AI requires massive amounts of electrical power to support its activities and millions of gallons of water to cool its data centers. One study predicts that, within the next five years, AI-driven data centers could produce enough air pollution to surpass the emissions of all cars in California.

Data centers on their own are water-intensive; California is home to at least 239. One study shows that a large data center can consume up to 5 million gallons of water per day, or as much as a town of 50,000 people. In The Dalles, Oregon, a local paper found that a Google data center used over a quarter of the city’s water. Artificial intelligence is even more thirsty: Reporting by The Washington Post found that Meta used 22 million liters of water simply training its open source AI model, and UC Riverside researchers have calculated that, in just two years, global AI use could require four to six times as much water as the entire nation of Denmark.

Many U.S. data centers are based in the western portion of the country, including California, where wind and solar power is more plentiful — and where water is already scarce. In 2022, a researcher at Virginia Tech estimated that about one-fifth of data centers in the U.S. draw water from “moderately to highly stressed watersheds.”

According to the Fifth National Climate Assessment, the U.S. government’s leading report on climate change, California is among the top five states suffering economic impacts from climate crisis-induced natural disaster. California already is dealing with the effects of one water-heavy industry; the Central Valley, which feeds the whole country, is one of the world’s most productive agricultural regions, and the Central Valley aquifer ranks as one of the most stressed aquifers in the world. ClimateCheck, a website that uses climate models to predict properties’ natural disaster threat levels, says that California ranks number two in the country for drought risk.

In August 2021, the U.S. Bureau of Reclamation declared the first-ever water shortage on the Colorado River, which supplies water to California — including roughly a third of southern California’s urban water supply — as well as six other states, 30 tribal nations and Mexico. The Colorado River water allotments have been highly contested for more than a century, but the worsening climate crisis has thrown the fraught agreements into sharp relief. Last year, California, Nevada and Arizona agreed to long-term cuts to their shares of the river’s water supply.

Despite the precarity of the water supply, southern California’s Imperial Valley, which holds the rights to 3.1 million acres of Colorado River water, is actively seeking to recruit data centers to the region.

“Imperial Valley is a relatively untapped opportunity for the data center industry,” states a page on the Imperial Valley Economic Development Corporation’s website. “With the lowest energy rates in the state, abundant and inexpensive Colorado River water resources, low-cost land, fiber connectivity and low risk for natural disasters, the Imperial Valley is assuredly an ideal location.” A company called CalEthos is currently building a 315 acre data center in the Imperial Valley, which it says will be powered by clean energy and an “efficient” cooling system that will use partially recirculated water. In the bordering state of Arizona, Meta’s Mesa data center also draws from the dwindling Colorado River.

The climate crisis is here, but organizers are not succumbing to nihilism. Across the country, community groups have fought back against big tech companies and their data centers, citing the devastating environmental impacts. And there’s evidence that local pushback can work. In the small towns of Peculiar, Missouri, and Chesterton, Indiana, community campaigns have halted companies’ data center plans

“The data center industry is in growth mode,” Jon Reigel, who was involved in the Chesterton fight, told The Washington Post in October. “And every place they try to put one, there’s probably going to be resistance. The more places they put them the more resistance will spread.”
