Rescue teams in Venezuela cling to hope as US rebuffs criticisms of government earthquake response

CATIA LA MAR, Venezuela (AP) — Black smoke from fires in flattened buildings and the smell of decomposing bodies spread across ruins Thursday, eight days after Venezuela’s devastating earthquakes, while rescue teams pulled on a thread of hope that they might still find survivors trapped beneath the rubble.

As officials carried body bags and stacked caskets in the port city of Catia La Mar, joy briefly broke through the pervading misery that has blanketed Venezuela's northern La Guaira on Thursday morning when rescue teams pulled a 43-year-old man out of the rubble he was buried under for nearly eight days.

Rescuers from across the Americas had worked for about 100 hours to pull Hernán Alberto Gil Flores from the collapsed shopping mall under which he was buried. Trapped in an air pocket, he'd survived on the water and sustenance rescuers passed him through the rubble. He was pulled out of the ruins on a stretcher and was carried to an ambulance as throngs of people cheered in a rare moment of victory.

Thousands more did not make it that far.

Venezuela's government said as of Wednesday that at least 2,295 were killed and more than 11,000 were wounded. Thousands more were sleeping in crowded shelters or outside, or remained missing as family members searched the rubble. The aftermath has left medics worried that the fallout could pave the way for a widening medical crisis of untreated injuries and infectious diseases in a healthcare system already on the brink.

Acting President Delcy Rodríguez continued to face mounting criticisms by Venezuelans over the government's inadequate handling of the earthquakes — civilian and international rescue efforts have far overshadowed the Venezuelan government response.

The criticism came just a day before the extension of Rodríguez’s 180-day mandate as acting leader was set to expire. Rodríguez served as deputy to former President Nicolás Maduro until he was ousted by the United States in January and she became interim leader with the backing of the Trump administration.

With little transparency by Venezuelan officials, it was unclear what would happen once the deadline passes on Friday.

Under Venezuela’s constitution, temporary absences are to be filled by the vice president — which was Rodríguez’s former role — for up to 90 days. These interim appointments can be extended by the national assembly for an additional 90 days.

The Venezuelan leader has strong support from lawmakers and the Trump administration. The National Assembly, controlled by Rodríguez’s party, can trigger a snap election if lawmakers declare the post permanently vacant.

The U.S. continued to throw support behind her government Wednesday in the face of criticism, and officials said there were 900 military personnel currently on the ground to support relief and rescue operations.

John M. Barrett, the U.S. chargé d’affaires to Venezuela, pushed back against accusations that Rodríguez was politicizing response efforts.

During a call with reporters, Barrett said the U.S. response “does require a high level of coordination with local authorities to be successful.”

“And what I can say with confidence is that the local authorities have fully complied with our requests and have accelerated this massive humanitarian response,” Barrett said.

Gen. Francis Donovan, head of U.S. Southern Command, added during the call that “decades of poor investment in the people of Venezuela” had “made this even more challenging for the current government.”

“It is a big problem for any leader to deal with a challenge of this magnitude,” Donovan said.

Corrects that the deadline for the acting president expires on Friday, not Thursday.

LOWELL, Mass. (AP) — Eileen Castle's swimming pool, one of the only ones for blocks around, was once a refuge for neighborhood children on hot summer days.

But even as temperatures soared this week, Castle, 82, said she won't be filling the pool — not with the data center behind her house buzzing with the sound of its industrial air conditioners and its backup diesel generators belching fumes at unexpected times.

“I think about the air quality, the water, what effects it has on the kids in the area,” she said on her front stoop as children whirred past on bicycles.

Hot weather of the kind sweeping the eastern U.S. drives up electricity demand for data centers, adding to their strain on power grids and worsening air quality for surrounding areas. The impact on communities like the racially diverse Sacred Heart neighborhood in Lowell, Massachusetts underscores why the artificial intelligence industry is feeling so much heat over the fast-sprouting facilities.

Around the country, data centers have been blamed increasingly for a host of environmental ills. Some tech industry figures say the facilities have become lightning rods for concerns over broader economic and societal changes posed by the AI boom.

But on sweltering days, it's hard not to see the effects on Castle's neighborhood, which the state has designated as facing higher environmental and health risks because of a population that's been historically excluded from political decision-making.

“It’s majority low-income and working family, family members who are working hard every day to just try to put food on the table,” said state Rep. Tara Hong, a Democrat who represents a heavily Cambodian American district in Lowell, a city of about 115,000 people northwest of Boston. “It’s an inclusive place there and that data center is just smack in the middle of everything.”

A heat wave is “almost the worst situation for data center operation,” said Shaolei Ren, a professor at the University of California, Riverside, who has studied AI’s environmental toll.

A data center’s racks of computer servers run hot and there are two ways to keep them running without interruption, Ren said: refrigeration-based cooling, which is energy-intensive, and evaporative cooling, which is water-intensive.

Some data centers will turn to backup diesel generators as a “preventative measure” to mitigate the likelihood of an outage, Ren said. If the grid is highly stressed, grid operators will sometimes ask data centers to turn on their generators as “the last line of defense,” Ren said.

Diesel emissions can have harmful effects on human health, even with short-term exposure. If too many diesel generators are fired up during heat waves, Ren said that could be "a disaster for the local air quality.″

The operator of the Lowell data center, the Markley Group, said it has planted more than 2,000 trees nearby to improve air quality. CEO Jeff Markley said in a statement to The Associated Press that the company has switched on generators in an emergency only a handful of times.

“They are not run proactively or continuously; they engage only during an actual power disruption to keep critical systems online, plus brief weekly testing of about five minutes per unit, run one generator at a time,” he said.

Markley said he chose Lowell because of its abundant water for cooling — supplied by the same Merrimack River that powered 19th century textile mills in the Industrial Revolution. He said the Lowell facility uses about 118,000 gallons of water per day at the peak of summer, a small fraction of the city's daily consumption.

Castle, a lifelong resident, was among those who welcomed the Markley Group a decade ago when it first started building on the site of an abandoned Prince spaghetti factory. But about two years ago, when the Markley Group added its second cooling tank behind her above-ground swimming pool, along with a growing number of surveillance cameras, the relationship had soured.

In response to growing opposition, Lowell's City Council voted 10-0 in February to pass a moratorium blocking further data center expansion for a year.

Data center electricity use has grown in the last few years, said Jonathan Koomey, a researcher who has been studying the computing warehouses for 30 years. But it’s “very much a local phenomenon,” he said. On a national scale, Koomey said demand growth has been moderate in recent years and he doesn't expect that to change.

“This is not a national crisis. It’s not explosive growth nationally,” he said. But in communities surrounding data centers, there are environmental costs, local economic costs, traffic and other concerns that need to be accounted for, Koomey added.

When temperatures climb into triple digits — as they’re expected to this week in New England — it’s harder to push heat out of a data center. Keeping it cool then requires more power, as is true of commercial buildings and homes. That can strain power grids and pose a “real risk” of power outages, Koomey said.

That strain looks different from the typical summer AC rush, when systems operators are dealing with “a lot of small loads" from individuals turning on home air conditioners, Koomey said.

“One of the challenges that the data center operators face is that these data centers are pretty big loads. They are big enough that they have to think about how to coordinate them and make sure that they’re not all cutting off at the same time or coming on at the same time,″ he said.

The North American Electric Reliability Corporation, a nonprofit that develops and enforces standards for the utility industry, recently issued an alert about the “unprecedented challenges from a surge in large power consumers” and developed guidelines to mitigate the "immediate risks posed″ by AI data centers.

Tensions ran so high in Lowell this week that police officers temporarily detained a 14-year-old girl who spoke out of turn at a city-led community forum on data center zoning.

“I’m not hurting anyone,” the girl shouted Monday after police officers escorted her from a middle school auditorium. “We just don’t want data centers!”

A coalition of data center opponents is increasingly clashing with electricians employed by Markley and other data center backers who say the facility boosts Lowell's ties to the tech industry.

Criticized for calling police to the contentious meeting and later asking an officer to remove the girl, Lowell Mayor Erik Gitschier, whose office is nonpartisan, told local talk radio station WCAP he didn't know her age at the time and defended his efforts to try to bring decorum to a topic he said deserves debate.

“It was warm out," he said. "You had people who had definite, passionate positions and they were screaming.”
