Operators of hyperscale data centers, those with more than 5,000 servers, are migrating to places where water is plentiful, such as Norway, but also to drought-prone places like Italy and Spain where energy is cheaper—and where extreme heat is becoming the norm.

A survey conducted last year by the Uptime Institute, a consulting firm, found that only 39% of data centers even tracked their water use, a 12 percentage-point drop from 2021. Tech companies in the past have refused to disclose information about individual centers’ energy and water consumption, claiming that such data was a trade secret.

Over the last couple of years, Google, Meta and Microsoft have started publishing their total water use across their operations, but they don’t break the number down by business unit nor use standardized metrics. Bluefield Research has estimated data centers use more than a billion liters of water per day, including water used in energy generation.

Operators often use shell companies to apply for planning permissions, and a data center can look like any large warehouse or factory from the outside.

Arman Shehabi, a researcher at the Lawrence Berkeley National Laboratory in California best known for a landmark paper on energy consumption at data centers, thinks the facilities could contribute to scarcity as droughts become longer and more intense. Part of the problem, he says, is that data center operators “are generally the last ones to the table to ask,” straining the system by asking for access to scarce water after agricultural interests and local communities have already come up with a plan. “Everybody is going to feel that,” he says.

Companies say data centers are getting more energy-efficient, but the increase in overall demand for computing power is outpacing such gains.

The specialized chips required for AI—broadly known as accelerators—emit so much more heat than general-purpose chips do that data center operators are having to rethink their cooling systems entirely

over time data centers will need to radically change the way they dissipate heat. The gold standard, he says, is a process called immersive cooling, in which servers are bathed in a special fluid that transfers heat from the chips. For now, operators are likely to opt for a hybrid model, wherein a high-performance section of the data center will be liquid-cooled while the rest will continue to use air conditioning

Amazon Web Services, Google and Microsoft have all made water stewardship pledges, promising to use more nonpotable and recycled water and to replenish more water than they consume operationally by 2030. This is the equivalent to offsetting carbon by planting trees—something that looks good on paper but may not directly benefit the communities affected by data centers, because water may be replenished only in places where it’s easy to do so.

It says, in effect, all options – deal, no deal, rethink – remain open, but you have three weeks to choose.

the EU27 wanted to move on because, quite simply, it has other things to deal with. Last week’s summit was once again hijacked by Brexit, which delayed a session on relations with China. Tensions with Russia, internal strains with the bloc’s nationalist governments, trade and security in the age of Trump, climate change, a slowing economy – all are more deserving of attention than Brexit.

“No deal would be bad news for all economically, even if it would be far worse for Britain than the 27,” a Dutch official said. “But politically it would be terrible. We had to find a way that left all options open for London – that basically ensured that no deal, if it happens, is Britain’s responsibility.”

Backed by the Dutch, Irish and others, Merkel also felt it would be a terrible idea for the EU’s future relationship with Britain to begin with the UK crashing out. “We will do everything we can to ensure this does not happen,”

Despite their exasperation with Brexit Britain, the EU27 recognise that the liberal postwar order now faces unprecedented challenges, and that no one in the bloc will be well served by a bitter divorce and a resentful, badly weakened UK. So a path to a reconsidered, potentially softer Brexit, entailing a relaxation of May’s red lines, should remain on the table for a little while yet.

China Central Television reported that farmers in a village in Henan Province were using wastewater from a paper mill to grow wheat. But one farmer said they would not dare to eat the wheat themselves. It is sold outside the village, perhaps ending up in cities, while the farmers grow their own wheat with well water

There is consensus now that China’s decades of double-digit economic growth exacted an enormous environmental cost. But growth remains the priority; the Communist Party’s legitimacy is based largely on rapidly expanding the economy, and China officially estimates that its G.D.P., which was $8.3 trillion in 2012, will grow at a rate of 7.5 percent this year and at an average of 7 percent in the five-year plan that runs to 2015. A Deutsche Bank report released last month said the current growth policies would lead to a continuing steep decline of the environment for the next decade, especially given the expected coal consumption and boom in automobile sales.

China may present the single most compelling factor. There is an increasing awareness that to deal with the challenge of China’s rapidly growing economy, Europe and the United States will have to learn to cooperate better

European leaders, including Prime Minister David Cameron of Britain and Chancellor Angela Merkel of Germany, have been pushing for a trade deal as a low-cost way of stimulating their struggling economies. The United States Chamber of Commerce and large companies like General Electric have also lobbied for an agreement

Potentially more important than abolishing tariffs, but also much more complicated, would be a deal that harmonized regulations on products like food, cars, toys and pharmaceuticals. Automobile manufacturers would like to see agreement on safety and emissions standards for cars, reducing or eliminating the need to build different versions for the American and European markets. Matthias Wissmann, head of the German Association of the Automotive Industry, said that harmonizing safety features would save several hundred dollars per automobile. Mr. De Gucht, who is expected to lead the talks on the European side, said that a deal could provide vital leverage over emerging powerhouses like China

Much of the global economy is operating free of artificial enhancements. Lower-skilled workers confront bleak opportunities and intense competition, especially in the United States. Even as recent data shows middle-class Americans are finally starting to share in the gains from the recovery, incomes for many remain below where they were a decade ago

technological disruption and economic upheaval are now at work in an era of scarcity

The worst financial crisis since the Great Depression has left banks from Europe to the United States reluctant to lend. Real estate bonanzas from Spain to Southern California gave way to a disastrous wave of foreclosures, eliminating construction jobs. China’s slowdown has diminished its appetite for raw materials, sowing unemployment from the iron ore mines of Brazil to the coal pits of Indonesia.

Trade did not cause the breakdown in economic growth. Indeed, trade has helped generate what growth remains. But the pervasive stagnation has left little cover for those set back by globalization.

China’s entry into the World Trade Organization in 2001 unleashed a far larger shock, but a construction boom absorbed many laid-off workers.

“We do need to have these trade agreements,” Mr. Bown said, “but we do need to be cognizant that there are going to be losers and we need to have policies to address them.”

Corporations that used China to cut costs raised their value, enriching executives and ordinary investors.

Privacy Policy The casualties of China’s exports are far fewer, but they are concentrated. The rugged country of western North Carolina suffered mass unemployment as Chinese-made wooden furniture put local plants out of business. So did glassmakers in Toledo, Ohio, and auto parts manufacturers across the Midwest.

Even among those who support trade, doubts are growing about its ability to deliver on crucial promises. A 2014 Pew Research Center survey of people in 44 countries found that only 45 percent of respondents believed trade raises wages. Only 26 percent believed that trade lowers prices.

Workers employed in major export industries earn higher wages than those in domestically focused sectors.Americans saw their choice of products expand by one-third in recent decades, the Federal Reserve Bank of Dallas found. Trade is how raspberries appear on store shelves in the dead of winter.

In the fallout, the United States maintained limits on unemployment benefits, leaving American workers vulnerable to plummeting fortunes. Social welfare systems have limited the toll in Europe, but economic growth has been weak, so jobs are scarce.

automation has grown in sophistication and reach. Between 2000 and 2010, the United States lost some 5.6 million manufacturing jobs, by the government’s calculation. Only 13 percent of those job losses can be explained by trade, according to an analysis by the Center for Business and Economic Research at Ball State University in Indiana. The rest were casualties of automation or the result of tweaks to factory operations that enabled more production with less labor.

if robots are a more significant threat to paychecks, they are also harder to blame than hordes of low-wage workers in overseas factories.“We have a public policy toward trade,” said Douglas A. Irwin, an economist at Dartmouth College. “We don’t have a public policy on automation.”

China’s relentless development was turning farmland into factories, accelerated by a landmark in the history of trade: the country’s inclusion in the World Trade Organization.The W.T.O. was born out of the General Agreement on Tariffs and Trade, a compact forged in 1947 that lowered barriers to international commerce in an effort to prevent a repeat of global hostilities.In the first four decades, tariffs on manufactured wares plunged from about 35 percent to nearly 6 percent, according to the Federal Reserve Bank of Chicago. By 2000, the volume of trade among members had swelled to 25 times that of a half-century earlier.

Mexico — home to about 123 million people — was not big enough to refashion the terms of trade. When China joined the W.T.O. in 2001, that added a country of 1.3 billion people to the global trading system

The anti-trade backlash, building for years, has become explosive because the global economy has arrived at a sobering period of reckoning. Years of investment manias and financial machinations that juiced the job market have lost potency, exposing longstanding downsides of trade that had previously been masked by illusive prosperity.

Chinese imports eliminated nearly one million American manufacturing jobs between 1999 and 2011. Add in suppliers and other related industries, and the total job losses reach 2.4 million.

Mr. Trump vows to slap punitive tariffs on Chinese goods. But that would very likely just shift production to other low-wage countries like Vietnam and Mexico. It would not turn the lights on at shuttered textile plants in the Carolinas. (Even if it did, robots would probably capture most of the jobs.)

Trade Adjustment Assistance, a government program started in 1962 and expanded significantly a dozen years later, is supposed to support workers whose jobs are casualties of overseas competition. The program pays for job training.But Mr. Simmons rolls his eyes at mention of the program. Training has almost become a joke. Skills often do not translate from old jobs to new. Many workers just draw a check while they attend training and then remain jobless.

European workers have fared better. In wealthier countries like Germany, the Netherlands, Sweden and Denmark, unemployment benefits, housing subsidies and government-provided health care are far more generous than in the United States.In the five years after a job loss, an American family of four that is eligible for housing assistance receives average benefits equal to 25 percent of the unemployed person’s previous wages, according to data from the Organization for Economic Cooperation and Development. For a similar family in the Netherlands, benefits reach 70 percent.

Yet in Europe, too, the impacts of trade have been uneven, in part because of the quirks of the European Union. Trade deals are cut by Brussels, setting the terms for the 28 member nations. Social programs are left to national governments.

In China, farmers whose land has been turned into factories are making more steel than the world needs. Advertisement Continue reading the main story In America, idled steel workers are contemplating how to live off the land.

a provision that would enable multinational companies to sue governments for compensation when regulations dent their profits.Esso, a subsidiary of Exxon Mobil, the American petroleum company, has operations in the Netherlands. Suppose the government went ahead with plans to limit drilling to protect the environment?“They could sue the Dutch state,” he fumed. “We are not so sure in the Netherlands whether we want to give the multinationals so much power. We are a trading country, but it’s not always that trade should prevail against quality of life.”

the longshoremen fret about robots

Now, many longshoremen sit in glass-fronted offices set back from the docks, controlling robotic arms via computer terminals.

The robots will win in the end, because robots never strike. Robots improve with time.

Trade deals, immigrant labor, automation: As Mr. Arkenbout sees it, these are all just instruments wielded in pursuit of the same goal — paying him less so corporations can keep more.“When they don’t need me anymore,” he said, “I’m nothing.”

The treaty would for the first time establish common international standards for authorizing international arms transfers, including basic regulations and approval protocols that would improve transparency and accountability. A prime purpose, according to the draft, is to “prevent, combat and eradicate the illicit trade in conventional arms and their diversion to illegal and unauthorized end use.” It would also prohibit signatories from transferring conventional weapons that violate arms embargoes or enable those who commit genocide, crimes against humanity and war crimes.
