On Monday, SpaceX amended its initial public offering to state that water conditions—including water scarcity, regulations around water, and drought—could constrain data center development.

It isn’t the only tech company trying to assess how water scarcity might impact its business. Water use is emerging as one of the most contentious data center issues. A recent Gallup poll found that seven out of 10 Americans are opposed to data center development, with water scarcity ranking as the top resource concern. Facing increasingly fierce resistance, some tech companies are scrambling to assure the public that they’re facing the issue head-on.

Data centers primarily use water to cool server racks, which throw off massive amounts of heat. One popular technique, known as evaporative cooling, uses fresh water to absorb the heat, which is then pumped to cooling towers where it evaporates outside.

Using more water can save money and reduce emissions for big tech companies by reducing the power needed for cooling that relies on energy-intensive pumps to recirculate water. But it can also come with a large water footprint: Google’s facility in Council Bluffs, Iowa, for instance, which uses evaporative cooling, consumed more than 1 billion gallons in 2024.

Lawrence Berkeley National Laboratory predicted in a 2024 report that hyperscale data centers could consume up to 33 billion gallons of water by 2030 if they relied heavily on evaporative cooling. That’s on par or even less than other thirsty industries, like agriculture or oil and gas—a single fracked well can use 1.5 to 16 million gallons of water—but it poses a risk in regions where water is already scarce. The risk is particularly acute in summer, when data center cooling needs tend to skyrocket at the same time as municipal water use.

“Water is a highly local, highly regional issue,” says Shaolei Ren, a professor of engineering at UC Riverside. “It's a limited resource, and we have to manage it very carefully.”

Some tech giants, including Microsoft, OpenAI, and Oracle, have made statements in recent months indicating that they are moving away from evaporative cooling entirely in order to save water. That includes OpenAI and Oracle’s massive Stargate expansion in a number of states, including a water-stressed region of Texas.

Google is taking a different approach. On Wednesday, the company rolled out a series of water-related commitments to communities where it has data centers, along with funding announcements for water-related projects in the US.

They include pledges to replenish more freshwater than the company consumes, via investments in local water projects; to scale up the use of reclaimed and recycled water; and to disclose annual water use in data centers. (Other tech companies, including Microsoft, have similar promises around water replenishment and local investment. Google has been working on most of these pledges for a few years.) There’s also a promise to use “a data-driven framework” to decide what data center designs would work best with local watersheds.

Ben Townsend, the global head of infrastructure and sustainability at Google, says that data center design is a lot more complicated than simply swearing off one type of cooling in all cases. The company, he says, has been doing detailed hydrologic assessments of its sites for the past four years to determine what types of cooling would work best.

“Water is scarce in some regions and plentiful in others,” he says. “A one-size-fits-all strategy just doesn't work.”

In April, Google defended evaporative cooling for areas with what it called “abundant” water in a filing to the European Union as necessary for developing truly sustainable data centers. Google’s arguments line up with new research from Ren and his team, who found that if all data centers in the US were to adopt some kind of evaporative cooling during peak demand, it could free up an additional 10 to 30 gigawatts of power. In areas where grids are stressed but water resources aren’t, using evaporative cooling could provide a meaningful headroom to utilities trying to balance load.

“If you don't use water, the challenge is that you're going to be using a lot more power in the summer, and that will push up the cost,” Ren says.

Most tech giants, including Google, have seen their carbon emissions skyrocket as a result of the AI boom. Totally avoiding evaporative cooling could increase emissions if data centers rely on dirty energy to keep facilities cool. Using less evaporative cooling could also mean more water used offsite for electric generation, depending on how data centers are getting their electricity.

Despite efforts to curb water use, tech companies are still struggling to do so—and it could eventually impact business. Even as Microsoft is moving away from evaporative cooling, The New York Times reported in February that the company’s internal records indicate that its water use is set to skyrocket. In 2024, Google halted plans for a data center outside of Santiago, Chile, after a court partially revoked its permits over water concerns. (The permits for that data center were granted in 2020; Townsend says the company adopted its water scarcity framework for new locations a few years after that.)

In 2021, Google funded a lawsuit filed by a town in Oregon fighting a local newspaper to avoid disclosing how much water the tech giant would use for an expansion of its existing data center. The company began disclosing water use from specific data centers in annual reports in 2023.

Priscilla Johnson, an independent consultant who served as Microsoft’s director of water strategy between 2017 and 2020, agrees with Ren that there’s trade-offs between water and power. However, she says, there are ways to push companies to develop better designs that use both less water and energy. Public pushback and regulation, she says, is crucial.

“The industry has to be challenged to design smarter and simplify things,” she says

The recently-incarcerated former congressman George Santos allegedly placed bets on himself, then acted to ensure he won.

The Trump administration is moving to dismantle the National Science Foundation's $368 million Ocean Observatories Initiative, a network of more than 900 deep-sea instruments used to monitor ocean currents, marine ecosystems, carbon absorption, heat waves, fisheries, coastal flooding, and climate change. The NSF said it would send ships in June to begin the removal of the instruments anchored off Oregon, Washington, Alaska, North Carolina, and an area between Greenland and Iceland known as the Irminger Sea. The New York Times reports: The ocean observation system began operating in 2016 and was expected to continue for 25 years. Jim Edson, a marine meteorologist who led the Ocean Observatories Initiative, called it "the world's most advanced continuously operating ocean observing systems." When it was first proposed, the science foundation said it was important to have a long-term presence at scientifically important sites in the Atlantic and Pacific oceans. Removing the instruments could take 15 months. Seismic instruments positioned around an active underwater volcano off Oregon will continue operating until 2028. Each observation station consists of several moorings that secure long arrays of devices connected to wires. The devices measure ocean currents as well as chemical and biological conditions from the water's surface down thousands of feet. The instruments were hardened to resist the pressure of the deep ocean, corrosive seawater as well as marine plants and animals that can foul electronics. Remotely controlled robotic vehicles and gliders around the moorings collect and transmit data to research laboratories. It cost $48 million annually to operate the network. The Trump administration repeatedly tried to shutter it, proposing to cut its funding by 80 percent in both 2025 and again in 2026. Congress pushed back, restoring the money. To try to reduce costs, managers turned off some of the instruments and collected less data, according to a December 2025 presentation about the observatories at the annual meeting of the American Geophysical Union, a nonprofit organization of scientists. Still, the science foundation moved ahead to decommission the observatory network.

Stanley Plotkin, 93, was instrumental in developing a number of vaccines over the course of his career. He recently said that he’s “beginning to regret having lived so long—because we’re going downhill.” How could we possibly have gotten here?

Maybe we’ve always been here. It turns out that the anti-vaccine arguments currently flooding the Internet have been around for as long as vaccines have. In his new book A Pox on Fools, Thomas Levenson breaks them down into three categories, as made clear in the book’s subtitle: “The True Believers, Grifters, and Cynics Who Convinced Us to Reject Vaccines.” The accusations these people levy against vaccines can just as easily be used to categorize the arguments themselves: They are wrong, they are bad, and they are intolerable.

Wrong

As Levenson tells it, in the early 18th century, a couple of forward-thinking Westerners learned about inoculations against smallpox from Ottoman women and an enslaved African. At that point, infectious disease was by far the leading cause of death, as it had been forever. In the 19th century, roughly 40 percent of babies died of infection before they turned 5.

(This is why the average lifespan back then was so low. It wasn’t that people didn’t live past their 30s; if they survived childhood, they largely did. It’s just that so, so many small children died that they dragged the average way down.)

When smallpox epidemics broke out in London and Boston in 1721, Lady Mary Wortley Montagu and Cotton Mather initiated inoculation campaigns in their respective cities. Inoculation involved taking pus from a pock of someone with a not-very-severe case of smallpox, making a cut in the arm of the person to be inoculated, and rubbing the pus into the cut.

There was an immediate backlash. It was morally wrong, some claimed, to interfere with the divine ordination of who would sicken and die and who would not. Only God had that ability, and to thwart it was to defy God’s will. It was hubris and blasphemy. Levenson highlights how the subtext of this attitude was that contracting a highly infectious disease was divine punishment for sin and that the only way to avoid disease was to live a virtuous life.

The Transcendentalists and Romantics substituted “nature” for “God” in the mid-19th century, but the argument has remained basically the same: vaccines are an affront to the “natural” world, and clean living is all you need to stay healthy. The implicit moral judgment remains, even without God: if you get sick, it must be because you ate/drank/breathed/wore something that wasn’t pure enough.

The immense strides in public hygiene and sanitation that preceded the heyday of vaccine development certainly did curb the spread of infection and increase lifespans, but clean living will not help you fight off an infection if you're exposed to a pathogen as effectively as a vaccine will.

The argument that it would ignores most of human history and what we know about microbiology and immunology. But it sounds quite compelling, especially when the modern world around us is so scary and hard to understand. And especially when almost no one alive today still remembers just how many child-sized coffins were involved in the halcyon pre-vaccine days when nature got to take its course.

Bad

Vaccines are unnecessary because our bodies can cure themselves, Robert F. Kennedy Jr. and his cronies claim. But they go beyond that and say they are actively harmful–and certainly more harmful than the diseases they are designed to prevent. This is an alluring argument to many, since the negative effects of vaccines are apparent (shots hurt for a moment, and you might get a sore arm or fever). In contrast, the lack of many small children dying from infectious diseases is harder to notice. Because of the spectacular success of vaccines, we take the lack of those deaths for granted.

This argument, too, has been there since the outset, when there was no data yet to refute it. And in the intervening years, there definitely were some tragic missteps during vaccine development and administration. But 300 years later, it's eminently clear that vaccines are safe. They are not completely risk-free, of course; nothing in life, certainly nothing valuable, is risk-free.

Vaccines can and have caused serious adverse effects (but not autism) in specific populations. And certain vaccines are not safe for certain subsets of people—infants, the elderly, or the immunocompromised. But this is not an argument that healthy people shouldn’t get them; rather, it's an argument precisely for why healthy people should get them. They keep circulating levels of pathogens low enough to protect those who cannot get vaccinated themselves, which brings us to the final argument.

Intolerable

This last thread has nothing to do with whether or not vaccines are effective, necessary, or safe. It is not a biological argument but a visceral, philosophical one. Because it is not anti-vaccine; it is anti-vaccine mandates. It is about the responsibilities that our governments have to us and that we have to each other, and about the inevitable clash between an individual’s needs and wants and the good of society as a whole.

The Supreme Court case of Jacobson v. Massachusetts lays out the two schools of thought. Boston and Cambridge enacted vaccine mandates during the smallpox epidemic of 1901, and Jacobson refused. He argued that “a compulsory vaccination law is… hostile to the inherent right of every freeman to care for his own body and health in such way as to him seems best.”

But the majority ruled that our liberties are not absolute. The Constitution does not allow us to do whatever we want—it is there to protect everyone’s rights and freedoms, and that entails sometimes curtailing each person’s rights and freedoms. Associate Justice John Marshall Harlan summarized: “Liberty itself, the greatest of all rights, is not unrestricted license to act according to one’s own will. It is only freedom from restraint under conditions essential to the equal enjoyment of the same right by others.”

The concept of herd immunity hadn’t been developed yet, but the court’s decision still relied on germ theory; refusing vaccination endangers those around you, and your liberty of bodily autonomy must be limited because insisting upon it infringes on everyone else’s right to health—and possibly life itself.

Facts and figures can demonstrate how many lives have been saved by vaccines. But they will never be an effective counterargument to “the government can’t tell me what to inject into my kid.” The only potential argument to sway someone who fervently believes that is appealing to their sense of solidarity—to the obligations that every member of society has to every other, to the sacrifices that everyone must make to ensure that society is safe for all. Alas, that sense of solidarity… does not seem to be at its peak in the US right now.

As Levenson makes clear, these three arguments have been plied for as long as vaccines have. But there are a couple of key differences now. The first is that 300 years ago, people who claimed that vaccines were either ineffective or harmful could be forgiven for thinking they had a point. But we now have germ theory to explain exactly how vaccines work and centuries of data showing how infection and death rates from every disease have plummeted once a vaccine was introduced to counter it. We know better.

The second is that now, arguments against vaccines tend to be touted by only one particular subgroup of people: Republicans. And that has come with predictable consequences. “In the US from 2021 onward,” Levenson writes, “being a Republican has become a measurable risk factor for illness and death.”

Levenson teaches in and has directed the Graduate Program in Science Writing at MIT, so you might expect his writing to be clear, concise, engaging, and informative, with an effective mix of statistics and anecdotes. You’d be right. And despite the incendiary nature of his topic, his tone remains measured throughout; he never descends into anger or ranting.

What does come through is his anguish that Robert F. Kennedy Jr.’s lies and policies will cause kids to needlessly be sickened by and die from diseases we have the tools to prevent.

On a blazing hot day in South Africa, female southern pied babblers can’t think straight. The medium-sized black-and-white birds are trying to get at tasty mealworms behind a see-through barrier. On cooler days, the birds can quickly figure out that all they have to do is go around the small wall of plastic. But when the mercury goes up, the birds just keep stubbornly pecking at the barrier.

That experiment is part of a growing body of research showing that animals get their minds muddled during heat waves. When it’s hot outside, birds struggle to learn, dogs bite more often, goat-like chamois pick fights. This is bad news not just for those who get on Fido’s toasted nerves. If the animals can’t stay alert enough to find food or avoid predators, their chances of survival go downhill, says Amanda Ridley, a behavioral ecologist at the University of Western Australia who coauthored the pied babbler study.

With climate change making heat waves more common, such cognitive impairments across the animal kingdom could ripple through entire ecosystems, putting already fragile species at greater risk. If pollinators forget which flowers to visit, crops and wild plants may fail. If birds can’t find food as easily, their young may not survive. And on a warming planet, a sharp mind is particularly vital. “A changing climate means that your ability to behaviorally adapt is even more important,” Ridley says.

Hotheaded

There is plenty of evidence that animals are affected by heat. Birds, for example, spend less time looking for food and feeding their young; they even sing less. Instead, they’ll sit around for hours with wings spread to dissipate the heat, and pant with their beaks wide open. Some animals retreat to shade or hide in cool burrows—again, skipping meals. Bees, meanwhile, splash their faces with droplets of water midflight when the weather is sizzling. This way, “they get convective cooling for their brain,” says Emily Baird, a neuroscientist at Stockholm University.

Some of the first hints that hot temperatures can mess up minds, however, came from studies on humans. Back in the 1800s, Belgian astronomer Adolphe Quetelet noticed that violent crime in France peaked in the summer. Later studies linked high temperatures with gun violence, mental-health-related hospital admissions, suicide, and gambling. When it’s hot, people have trouble making decisions, and their memory suffers. For students at schools without air conditioning, a school year just one degree Fahrenheit hotter reduces test scores by 1 percent, a study found.

Increasingly, there’s evidence that other species may also be more aggressive when mercury shoots up. A 2023 study that combed through nearly 70,000 reports of dogs biting people across eight US cities, from Chicago to Baltimore, found that such incidents were more likely to happen on hot, sunny, and smoggy days. The risk was 10 percent higher on a 90° F day than on a 60° F day—and not only because people are more apt to venture out for walks when the sun is shining (the researchers controlled for seasonal effects in their data).

Still, the scientists were unable to determine whether dogs get more aggressive as it gets hot, or if cranky humans provoke more attacks. “It’s likely that both humans and dogs get stressed and more irate at higher temperatures,” said Clas Linnman, a neuroscientist at the University of Miami and a coauthor on the study.

And it’s not only dogs: A 2025 study out of China showed that many animals, including snakes and cats, are more inclined to bite people when it gets hot.

Animals also seem to lose their cool with each other, especially if there is food involved. Scientists used binoculars and spotting scopes to spy on wild goat-like chamois that feed on protein-rich plants on the slopes of the Italian Apennine Mountains. More than 1,600 hours of observations over two summers revealed that when temperatures rose from 54° to 64° F, vegetation grew scarcer, and chamois aggression in turn shot up. The animals became territorial over patches of food, they assumed threatening postures, chased each other—attacks that, at times, escalated. The study authors predict that chamois aggression will go up 50 percent by 2080 due to climate change.

The small tropical fish called a golden julie also gets confrontational in the heat. Ordinarily, when a golden julie is placed in front of a mirror, it sees its reflected image as a stranger and shows some hostility, raising its fin, for example. But if the normally 78° water is raised to a hot 84°, the fish is more likely to get aggressive, and may bite and slap its tail against the mirror, as it tries to scare or attack the reflected image.

Cognitive problems

Heat waves can also hamper the ability of animals to learn, as Ridley and her colleagues observed with the southern pied babblers. In one of their experiments, the birds were presented with a simple wooden block with two holes drilled in it, each covered with a lid. If the bird pecked at the lid, it would rotate, revealing either an empty hole or a tasty mealworm (the babblers, Ridley says, “are highly motivated by mealworms”). One lid was dark, and the other a lighter shade of the same color. During heat waves, the birds needed twice as many trials to learn that the mealworm was always hidden under the lid of the same shade.

Another group of scientists tested zebra finches, pretty Australian songbirds, and discovered that if temperatures are high, they too have cognitive problems. When figuring out how to get a mealworm out of a see-through tube with an opening at one end, they would just keep pecking on the tube, says study coauthor Elizabeth Derryberry, an evolutionary biologist at the University of Tennessee, Knoxville. It’s the bird equivalent of “banging your head against a brick wall,” she says.

Adding to the tally, several years ago researchers showed that when the heat is on, mice have trouble finding their way around a maze and forget objects they’ve seen the day before. More recently, researchers found that male guppies, popular aquarium fish, also have trouble getting through a maze after spending several days in heat-wave-like 90° water, even if the prize for getting it right is a virgin female—which they tend to find particularly attractive.

For animals such as fish and insects that can’t control their body temperature, heat waves could be particularly detrimental. “Changes in air temperature will affect brain temperature,” says Baird. A hotter brain could hinder the functioning of nerves, and that, she says, “might affect sensing, memory, and learning.”

When Baird and colleagues tried to teach bumblebees to associate sweet sucrose with the color blue and bitter quinine with yellow, most of the bumblebees learned the trick at 77°, but fewer than half managed to do so at 90°. Such impaired cognition could spell trouble in the field: If the insects forget which flowers they should pollinate (in the case of bumblebees, these include tomatoes and blueberries) or how to get back home with nectar, not only will the pollinators suffer, but human agriculture too, Baird says.

Heat appears to dangerously diminish animal vigilance as well. In Ridley’s recent experiments, once mercury in the Kalahari Desert reached 96° F, pied babblers lost their ability to properly respond to predators. In their studies, researchers lured birds toward a mystery shape covered in a sandy-colored blanket, using worms as bait. Once a babbler approached, the scientists would reveal what was hidden underneath: either a taxidermied cat-like carnivore called a genet, or a similarly sized and colored wooden box. The birds got scared of the genet in cooler temperatures—they’d call out, scan their surroundings, or simply flee. But once it got hot, they behaved similarly whether they were facing the carnivore or the box. Ridley suggests that this could translate into higher chances of fatal predator attacks as heat rises, which could harm populations of babblers and other prey species.

These studies are not just abstractions. In the Kalahari, where southern pied babblers use their wits to search for worms, temperatures are rising twice as fast as the global average. In tropical rivers, where male guppies seek mates, heat waves are growing longer and more intense. It’s the same story across much of the planet—temperatures climb, and animal thinking becomes strained, potentially putting species at risk. The effects may be magnified in certain areas such as cities, which often exhibit even warmer temperatures than non-urban areas. If anything, Ridley says, “We are probably underestimating the impacts of increased heat on animal minds.”

A GRAPHIC DISSERTATION THAT ARGUES FOR THE POWER OF IMAGES OVER TEXT AS A WAY TO TEACH

Unflattening
by Nick Sousanis
Harvard University Press
2015, 208 pages, 7.5 x 10.2 x 1 inches

It is remarkable how much we learn in our youth and how fast we learn it. It is a pace that really cannot sustain itself as we age, though we might try to continue to learn as though we were young. In my youth, the newspaper seemed a vast swarm of text and a few images that encircled a hidden prize: the funnies. Comics, in youth, are acceptable, but as we age we regard them more as juvenile diversions. Over time, the picture book gives way to the novel. The non-fiction works in the form of text books and scholarly journals are tools to educate us. Finally, should we pursue learning down the institutional path long enough, we encounter doctoral theses with their many and myriad intertextual references. It is a long-standing joke among academics that it is rare that the thesis they slave over for four or more years ever actually gets read.

Nick Sousanis, with his doctoral thesis Unflattening, is a poignant departure from any trend of dissertations written for the sake of being written. More than that, it is meant to be more than a read work. It is an experiential work that asks the reader to not just read, but rather to participate in learning to appreciate imagery on equal terms with orderly lines of written text. This is a dissertation written in comic book format that argues for the power of that medium. One might think about the adage concerning the worth of pictures and thousands of words, and that does come up in the work itself, but this is something more than a trite saying. It is a masterful reinterpretation of how we read and learn, and how our world can be captured and conveyed to our fellows. It dismantles the rigid presumptions we have regarding the inherent value of the written word – especially scholarly writing. It champions the comic, for “while the image is, the text is always about.” Indeed, it is brilliantly argued throughout that “the visual provides expression where words fail.”

The title, Unflattening, refers to Edwin A. Abbott’s novella Flatland (1884), about a dystopian flatland of two dimensional objects, where a coin would not be seen by others for its circular shape, but rather would be seen edge-on as just a line obscuring the horizon. This is a “linelander,” and all linelanders see each other this way. A square of three dimensions frees the coin-shaped object by peeling it from the flat surface so that it might see its brethren and world from above – from the third dimension, just as we would look down upon a page in a geometry textbook

Sousanis, similarly, wishes to peel us away from the linear predominance of the textual world where word follows word follows word. He comes from a background in comics, graphic novels, or whatever phrase you would use to describe his art. Just as his square peels away the coin from lineland to reveal it to be flatland, so too Sousanis convinces us, by both text and deed, of the power of comics. His text is often sparse and pared down to its most necessary elements, but the accompanying visuals draw the eye along and serve as an obvious example that reinforces the sometimes vague text. The deed is the image, for it is the more obvious representation of our lived world, while the text can only describe it. This may all seem obvious, but Sousanis brings to bear so many examples and graphical displays to reinforce his line of argument, that the journey through this work is quite remarkable. Moreover, his endnotes at the back serve not only to acknowledge his textual sources, but also to draw attention to and explain his visual inspirations. Those images that so often sit confined within frames within museum galleries or as a ghettoized section of glossy pages in the middle of an art book, they are given life and agency by Sousanis’ deploying of them as allies to his words.

Certainly, it is almost with chagrin that one must only write about such a work when it argues so convincingly that mere text is limited in its conveying of full meaning. It is some solace that the accompanying images from Sousanis’ work will allow readers of this review to gain greater insight in the majesty of his pairing of imagery and text. This is a thinking person’s book and it is most definitely academic, but it is also surprisingly accessible. It draws upon – and draws – so many disciplines and so many real-world instances, that anyone and everyone will find it illuminating. So profound are many of these moments of illumination that they go a long way to rejuvenating our desire to see the world anew, from a child’s eyes once more. – Stephen Webb.

FOR FANS INTERESTED IN THE HISTORY AND INSPIRATION BEHIND A BOY AND HIS TIGER

Exploring Calvin and Hobbes: An Exhibition Catalogue
by Bill Watterson and Robb Jenny
Andrews McMeel Publishing
2016, 160 pages, 8.5 x 11 x 0.6 inches

Buy on Amazon

I like many grew up on Calvin and Hobbes. I don’t know if there’s a comic, book, film, or any other piece of art that better captures a childhood. I read every Sunday strip, most of the dailies, and the ones that I missed I would read in dog-eared collection books checked out from the library. As I got older, I wanted to know more about the strip’s creation. When I picked up the Complete Calvin and Hobbes, a 14-pound tomb, I was a little disappointed. Other than an introduction, there was very little information about the mysterious creator Bill Watterson. Thankfully, Exploring Calvin and Hobbes: An Exhibition Catalogue makes up for that.

This is the Blu-Ray extras that Calvin & Hobbes fans have been waiting for. It’s not for those casually interested in reading the strip. There are plenty of other books for that. But if you’re interested in process, history, and the inspiration behind a boy and his tiger, you’re going to love this book.

The book explores an exhibit of Watterson’s work at the Billy Ireland Cartoon Museum. It also includes one of the most in-depth interviews he’s ever given. In it you get a rare look at his early work, the tools Watterson used, the struggles he went through, and the wonderful comic that he created. You get a real sense of the artistry that Watterson put into the strip, and how it evolved over the years. It’s great to relive and learn about something that had such an influence on me. This book is definitely a must-have for Calvin and Hobbes fans. – JP LeRoux
