Study: Ocean Currents Vital for Distributing Heat Could Collapse by Midcentury 

A system of ocean currents that transports heat northward across the North Atlantic could collapse by midcentury, according to a new study. Scientists have said that such a collapse could cause catastrophic sea level rise and extreme weather across the globe. 

In recent decades, researchers have both raised and downplayed the specter of Atlantic current collapse. It even prompted a movie that strayed far from the science. Two years ago, the U.N. Intergovernmental Panel on Climate Change said any such catastrophe was unlikely this century. But the new study published in Nature Communications suggests it might not be as far away and unlikely as mainstream science says. 

The Atlantic meridional overturning circulation is a vital system of ocean currents that circulates water throughout the Atlantic Ocean, according to the National Oceanic and Atmospheric Administration. It’s a lengthy process, taking an estimated 1,000 years to complete, but has slowed even more since the mid-1900s. 

A further slowdown or complete halting of the circulation could create more extreme weather in the Northern Hemisphere, sea level rise on the East Coast of the United States and drought for millions in southern Africa, scientists in Germany and the U.S. have said. But the timing is uncertain. 

In the new study, Peter and Susanne Ditlevsen, two researchers from Denmark, analyzed sea surface temperatures in the North Atlantic between 1870 and 2020 as a way of assessing this circulation. They found the system could collapse as soon as 2025 and as late as 2095, given current global greenhouse gas emissions.

“There are large uncertainties in this study, in many prior studies, and in climate impact assessment overall, and scientists sometimes miss important aspects that can lead to both over- and underprediction of impacts,” Julio Friedmann, chief scientist at Carbon Direct, a carbon management company, said in a statement. “Still, the conclusion is obvious: Action must be swift and profound to counter major climate risks.” 

Stefan Rahmstorf, co-author on a 2018 study on the subject, published an extensive analysis of the Ditlevesens’ study on RealClimate, a website that publishes commentary from climate scientists. While he said that a tipping point for the collapse of the Atlantic meridional overturning circulation was “highly uncertain,” he also called the IPCC estimate conservative. 

“Increasingly the evidence points to the risk being far greater than 10% during this century,” he wrote, “… rather worrying for the next few decades.”

Former Military Officials Testify Before US Congress About Extraterrestrials, Alien Craft

The U.S. government “absolutely” has recovered extraterrestrial craft, according to a former combat officer who was a member of a Department of Defense task force that investigated unidentified anomalous phenomena, or UAP.

Dave Grusch, in response to a House member’s questions during a congressional hearing Wednesday, said he knows the exact locations of such alien craft and that he had provided this information to the intelligence community’s inspector general.

Grusch, who has become a whistleblower and testified that he has faced retaliation for his revelations, told lawmakers that the U.S. government also possesses evidence of non-human biologics. Grusch did not elaborate, stating he had not seen any alien craft or beings himself, but was basing his testimony on dozens of interviews he had conducted within the U.S. intelligence community.

The Air Force veteran, who also worked for two intelligence agencies, was one of three former military officers who appeared before the House Oversight Committee’s national security subcommittee, which held a 135-minute open televised hearing on unidentified flying objects.

The technology “is beyond anything we have,” said David Fravor, who in 2004 as a U.S. Navy pilot videotaped off the coast of California a physics-defying flight of an object, known as the “Tic-Tac.”

“There’s four sets of human eyeballs [that witnessed the incident], we’re all very credible,” testified Fravor. “It’s not a joke.”

A third witness, Ryan Graves, was an F/A-18 Super Hornet U.S. Navy pilot stationed in Virginia in 2014 when his squadron first began encountering unknown objects. He described what he and his colleagues saw as a “dark gray or a black cube inside of a clear sphere” approximately 1.5 to 4.5 meters in diameter. Such incidents became so frequent, according to Graves, that air crews would discuss potential risks from the objects as a routine part of their pre-flight briefings.

Under questioning by a lawmaker, Graves said he knew the craft could not be of domestic origin because they were able to remain completely stationary in Category 4 hurricane winds and then could accelerate to supersonic speeds.

Graves said there were similar reports by military pilots and others from nearly everywhere in the world the U.S. Navy operates.

The hearing contained other sensational testimony, for which there has been no independent confirmation but is similar to statements the witnesses and others have made in recent years in mainstream media articles, including those published by The New York Times.

A Defense Department entity established to investigate UAP phenomena, the All-Domain Anomaly Resolution Office, is refuting Grusch’s claim that access to some materials for an earlier task force was denied.

“To date, AARO has not discovered any verifiable information to substantiate claims that any programs regarding the possession or reverse-engineering of extraterrestrial materials have existed in the past or exist currently. AARO is committed to following the data and its investigation wherever it leads,” said Sue Gough, a Pentagon spokesperson.

Grusch told the bipartisan group of lawmakers there is more classified information, including about a flying object the size of a football field, he could reveal “in a closed session at the right level.”

Lawmaker Anna Paulina Luna, a Republican from Florida, said the committee was denied access to the Secure Classified Information Facility, or SCIF, within the U.S. Capitol to hear further testimony from the witnesses regarding classified matters.

Several members of the committee pledged to work to make more information about the topic public.

“We’re trying to get to the bottom of it,” lawmaker Tim Burchett, a Tennessee Republican, said in expressing appreciation for the witnesses appearing at a public congressional hearing. “I want to thank everybody. We made history today.”

Lawmaker Robert Garcia, a freshman California Democrat, told the witnesses they “had a lot of courage” and characterized Wednesday’s hearing as the most bipartisan discussion he had experienced during his first seven months in Congress.

“Many Americans are deeply interested in this issue, and it shouldn’t take the potential of nonhuman origin to bring us together,” added lawmaker Jared Moskowitz, a Florida Democrat.

Luna recently accused the U.S. government of stonewalling lawmakers’ efforts for transparency, saying she and other lawmakers were rebuffed by officials when they went to an Air Force base in Florida seeking information on UAP sightings by military pilots.

“They refuse to answer questions posed by whistleblowers, avoiding the concerns of Americans and acknowledging the possible threat of UAPs poses to our national security as well as public safety,” Luna said at a news conference last week. “It is extremely unnecessary and an overclassification.”

During Wednesday’s session, Graves noted there are many more credible witnesses with significant information but who are “hesitant to come forward” because they fear ridicule and retaliation.” He said a centralized method for reporting sightings would circumvent potential retaliation, a system lawmakers expressed interest in creating through bipartisan legislation.

UAP are “a national security issue worth looking at,” according to John Kirby, a former Navy admiral, who is a National Security Council spokesman. He said the matter is taken seriously by President Joe Biden and his administration.

“In some cases, these phenomena have affected military training, have impacted military readiness,” Kirby told White House reporters following the congressional hearing. “The truth is we don’t have hard and fast answers on these things.”

Provocative Irish Singer Sinead O’Connor Dies at 56

Sinead O’Connor, the gifted Irish singer-songwriter who became a superstar in her mid-20s but was known as much for her private struggles and provocative actions as for her fierce and expressive music, has died at 56.

“It is with great sadness that we announce the passing of our beloved Sinead. Her family and friends are devastated and have requested privacy at this very difficult time,” the singer’s family said in a statement reported Wednesday by the BBC and RTE. No cause was disclosed.

She was public about her mental illness, saying that she’d been diagnosed with bipolar disorder. O’Connor posted a Facebook video in 2017 from a New Jersey motel where she had been living, saying that she was staying alive for the sake of others and that if it were up to her, she’d be “gone.”

When her teenage son Shane died by suicide in 2022, O’Connor tweeted there was “no point living without him” and was soon hospitalized.

Recognizable by her shaved head and elfin features, O’Connor began her career singing on the streets of Dublin and soon rose to international fame. She was a star from her 1987 debut album “The Lion and the Cobra” and became a sensation in 1990 with her cover of Prince’s ballad “Nothing Compares 2 U,” a seething, shattering performance that topped charts from Europe to Australia and was heightened by a promotional video featuring the gray-eyed O’Connor in intense close-up.

She was a lifelong nonconformist — she would say that she shaved her head in response to record executives pressuring her to be conventionally glamorous — but her political and cultural stances and troubled private life often overshadowed her music.

A critic of the Catholic Church well before allegations sexual abuse were widely reported, O’Connor made headlines in October 1992 when she tore up a photo of Pope John Paul II while appearing live on NBC’s “Saturday Night Live” and denounced the church as the enemy. The next week, Joe Pesci hosted “Saturday Night Live,” held up a repaired photo of the pope and said that if he had been on the show with O’Connor, he “would have gave her such a smack.”

Days later, she appeared at an all-star tribute for Bob Dylan at Madison Square Garden and was immediately booed. She was supposed to sing Dylan’s “I Believe in You,” but switched to an a cappella version of Bob Marley’s “War,” which she had sung on “Saturday Night Live.”

Although consoled and encouraged on stage by her friend Kris Kristofferson, she left and broke down, and her performance was kept off the concert CD. (Years later, Kristofferson recorded “Sister Sinead,” for which he wrote, “And maybe she’s crazy and maybe she ain’t/But so was Picasso and so were the saints.”)

She also feuded with Frank Sinatra over her refusal to allow the playing of “The Star-Spangled Banner” at one of her shows and accused Prince of physically threatening her. In 1989 she declared her support for the Irish Republican Army, a statement she retracted a year later. Around the same time, she skipped the Grammy ceremony, saying it was too commercialized.

In 1999, O’Connor caused uproar in Ireland when she became a priestess of the breakaway Latin Tridentine Church — a position that was not recognized by the mainstream Catholic Church. For many years, she called for a full investigation into the extent of the church’s role in concealing child abuse by clergy.

In 2010, when Pope Benedict XVI apologized to Ireland to atone for decades of abuse, O’Connor condemned the apology for not going far enough and called for Catholics to boycott Mass until there was a full investigation into the Vatican’s role, which by 2018 was making international headlines.

“People assumed I didn’t believe in God. That’s not the case at all. I’m Catholic by birth and culture and would be the first at the church door if the Vatican offered sincere reconciliation,” she wrote in The Washington Post in 2010.

O’Connor announced in 2018 that she had converted to Islam and would be adopting the name Shuhada’ Davitt, later Shuhada Sadaqat — although she continued to use Sinead O’Connor professionally. 

“Her music was loved around the world and her talent was unmatched and beyond compare,” Irish Prime Minister Leo Varadkar said in a statement on social media. 

O’Connor was born on December 8, 1966. She had a difficult childhood, with a mother whom she alleged was abusive and encouraged her to shoplift. As a teenager she spent time in a church-sponsored institution for girls, where she said she washed priests’ clothes for no wages. But a nun gave O’Connor her first guitar, and soon she sang and performed on the streets of Dublin, her influences ranging from Dylan to Siouxsie and the Banshees.

Her performance with a local band caught the eye of a small record label, and, in 1987, O’Connor released “The Lion and the Cobra,” which sold hundreds of thousands of copies and featured the hit “Mandinka,” driven by a hard rock guitar riff and O’Connor’s piercing vocals. O’Connor, 20 years old and pregnant while making “Lion and the Cobra,” co-produced the album.

“Nothing Compares 2 U” received three Grammy nominations and was the featured track off her acclaimed album “I Do Not Want What I Haven’t Got,” which helped lead Rolling Stone to name her Artist of the Year in 1991.

O’Connor announced she was retiring from music in 2003, but she continued to record new material. Her most recent album was “I’m Not Bossy, I’m the Boss,” released in 2014 and she sang the theme song for Season 7 of “Outlander.”

The singer married four times; her union to drug counselor Barry Herridge, in 2011, lasted just 16 days. O’Connor had four children: Jake, with her first husband John Reynolds; Roisin, with John Waters; Shane, with Donal Lunny; and Yeshua Bonadio, with Frank Bonadio.

In 2014, she said she was joining the Irish nationalist Sinn Fein party and called for its leaders to step aside so that a younger generation of activists could take over. She later withdrew her application.

Jury Acquits Kevin Spacey in London on Sexual Assault Charges Dating Back to 2001

A London jury acquitted Kevin Spacey on sexual assault charges on Wednesday after a four-week trial in which the actor said he was a “big flirt” who had consensual flings with men and whose only misstep was touching a man’s groin while making a “clumsy pass.”

Three men accused the Oscar winner of aggressively grabbing their crotches. A fourth, an aspiring actor seeking mentorship, said he awoke to the actor performing oral sex on him after going to Spacey’s London apartment for a beer and either falling asleep or passing out.

All the men said the contact was unwanted but Spacey testified that the young actor and another man had willingly participated in consensual acts. He said a third man’s allegation that he grabbed his privates like a striking “cobra” backstage at a theater was “pure fantasy.”

He said he didn’t remember a fourth incident at a small party at a home he rented in the country but accepted that he touched the groin of a man he had met at a pub during a night of heavy drinking. He said he had misread the man’s interest in him and said he had probably made an awkward pass.

Defense lawyer Patrick Gibbs said three of the men were liars and incidents had been “reimagined with a sinister spin.” He accused most of them of hopping on a “bandwagon” of complaints in the hope of striking it rich.

Prosecutor Christine Agnew told jurors that Spacey was a “sexual bully” who took what he wanted when he wanted. She said he was shielded by a “trinity of protection”: he knew men were unlikely to complain; they wouldn’t be believed if they did complain; and if they did complain, no action would be taken because he was powerful.

Spacey, who turned 64 on Wednesday, faced nine charges, including multiple counts of sexual assault and one count of causing a person to engage in penetrative sexual activity without consent.

The accusations date from 2001 to 2013 and include a period when Spacey — after winning Academy Awards for “The Usual Suspects” and “American Beauty” — had returned to the theater, his first love. During most of that period he was artistic director of the Old Vic Theatre in London.

The men came forward after an American actor accused Spacey of an incident of sexual misconduct as the #MeToo movement heated up in 2017.

Several of the men said they had been haunted by the abuse and couldn’t bear to watch Spacey’s films.

One of the men broke down when speaking with police as he provided details in a videotaped interview about the oral sex incident that he said he’d never told anyone before. Another man said he was angry about the abuse that occurred sporadically over several years and began to drink and work out more to cope with it.

Spacey choked up and became teary eyed in the witness box as he described the emotional and financial turmoil that the U.S. accusations brought and the barrage of criticism that followed on social media.

“My world exploded,” Spacey testified. “There was a rush to judgment and before the first question was asked or answered I lost my job, I lost my reputation, I lost everything in a matter of days.”

Gibbs said Spacey was being “monstered” on the internet every night and became toxic in the industry.

Spacey was booted from “House of Cards” and his scenes in “All the Money in the World,” were scrubbed and he was replaced by Christopher Plummer. Aside from some small projects, he has barely worked as an actor in six years.

A New York jury last year swiftly cleared Spacey in a $40 million lawsuit by “Star Trek: Discovery” actor Anthony Rapp on allegations dating back three decades.

Spacey had viewed the London case as a chance for redemption, telling German magazine Zeit last month that there were “people right now who are ready to hire me the moment I am cleared of these charges in London.”

US Works With Artificial Intelligence Companies to Mitigate Risks

Can artificial intelligence wipe out humanity?

A senior U.S. official said the United States government is working with leading AI companies and at least 20 countries to set up guardrails to mitigate potential risks, while focusing on the innovative edge of AI technologies.

Nathaniel Fick, the U.S. ambassador-at-large for cyberspace and digital policy, spoke Tuesday to VOA about the voluntary commitments from leading AI companies to ensure safety and transparency around AI development.

One of the popular generative AI platforms is ChatGPT, which is not accessible in China. If a user asked it politically sensitive questions in Mandarin Chinese such as, “What is the 1989 Tiananmen Square Massacre?” the user would get information that is heavily censored by the Beijing government.

But ChatGPT, created by U.S.-based OpenAI, is not available in China.

China has finalized rules governing its own generative AI. The new regulation will be effective August 15. Chinese chatbots reportedly have built-in censorship to avoid sensitive keywords.

“I think that the development of these systems actually requires a foundation of openness, of interoperability, of reliability of data. And an authoritarian top-down approach that controls the flow of information over time will undermine a government’s ability, a company’s ability, to sustain an innovative edge in AI,” Fick told VOA.

The following excerpts from the interview have been edited for brevity and clarity.

VOA: Seven leading AI companies made eight promises about what they will do with their technology. What do these commitments actually mean?

Nathaniel Fick, the U.S. ambassador-at-large for cyberspace and digital policy: As we think about governance of this new tech frontier of artificial intelligence, our North Star ought to be preserving our innovative edge and ensuring that we can continue to maintain a global leadership position in the development of robust AI tools, because the upside to solve shared challenges around the world is so immense. …

These commitments fall into three broad categories. First, the companies have a duty to ensure that their products are safe. … Second, the companies have a responsibility to ensure that their products are secure. … Third, the companies have a duty to ensure that their products gain the trust of people around the world. And so, we need a way for viewers, consumers, to ascertain whether audio content or visual content is AI-generated or not, whether it is authentic or not. And that’s what these commitments do.

VOA: Would the United States government fund some of these types of safety tests conducted by those companies?

Fick: The United States government has a huge interest in ensuring that these companies, these models, their products are safe, are secure, and are trustworthy. We look forward to partnering with these companies over time to do that. And of course, that could certainly include financial partnership.

VOA: The White House has listed cancer prevention and mitigating climate change as two of the areas where it would like AI companies to focus their efforts. Can you talk about U.S. competition with China on AI? Is that an administration priority?

Fick: We would expect the Chinese approach to artificial intelligence to look very much like the PRC’s [People’s Republic of China] approach to other areas of technology. Generally, top down. Generally, not focused on open expression, not focused on open access to information. And these AI systems, by their very definition, require that sort of openness and that sort of access to large data sets and information.

VOA: Some industry experts have warned that China is spending three times as much as the U.S. to become the world’s AI leader. Can you talk about China’s ambition on AI? Is the U.S. keeping up with the competition?

Fick: We certainly track things like R&D [research and development] and investment dollars, but I would make the point that those are inputs, not outputs. And I don’t think it’s any accident that the leading companies in AI research are American companies. Our innovation ecosystem, supported by foundational research and immigration policy that attracts the world’s best talent, tax and regulatory policies that encourage business creation and growth.

VOA: Any final thoughts about the risks? Can AI models be used to develop bioweapons? Can AI wipe out humanity?

Fick: My experience has been that risk and return really are correlated in life and in financial markets. There’s huge reward and promise in these technologies and of course, at the same time, they bring with them significant risks. We need to maintain our North Star, our focus on that innovative edge and all of the promise that these technologies bring in. At the same time, it’s our responsibility as governments and as responsible companies leading in this space to put the guardrails in place to mitigate those risks.

US Rejoins UNESCO Cultural and Educational Organization  

First Lady Jill Biden Tuesday marked the United States’ return to the United Nations’ cultural organization after five years away, amid concerns that its absence has let China take a lead in key areas like artificial intelligence and technology education.

“I was honored to join you today as we raise the flag of the United States, a symbol of our commitment to global collaboration and peace,” Biden said in Paris, as the American flag joined 193 others under the shadow of the city’s major cultural landmark, the Eiffel Tower. “The United States is proud to join as a member state of UNESCO. Madam Director-General, you’ve worked long and hard to help us realize this goal.”

The roots of the withdrawal date back to 2011, when the United Nations Educational, Scientific and Cultural Organization gave Palestine full membership as a state. Palestine is not a U.N.-recognized state. That led the Obama administration to freeze U.S. financial contributions to UNESCO – about a fifth of the agency’s budget.

[[https://www.everycrsreport.com/reports/R42999.html]].

In 2017, the U.S. State Department cited “mounting arrears at UNESCO, the need for fundamental reform in the organization, and continuing anti-Israel bias at UNESCO” as reasons to complete the withdrawal the following year.

The Biden administration now faces a $619 million debt. The Biden administration has asked for $150 million in the 2024 budget.

UNESCO also has designated 1,157 properties around the world as having major cultural significance, including the ancient town of Bethlehem, technically in Israel but classified by UNESCO as being in Palestine.

The prominent American Jewish Committee told VOA they supported the U.S. decision to rejoin UNESCO despite its concerns about what it sees as lack of recognition of Jewish culture and the Jewish state.

“UNESCO is an important agency,” Jason Isaacson, chief policy and political affairs officer for the American Jewish Committee, told VOA. “It’s not perfect. Nor is any other U.N. entity. But it does really important work. And it is a vehicle for soft power, for the exercise of soft power in the United States to not be in that agency meant that other players — competitors, rivals of the United States — could have a seat at the table, could have cultural programs, scientific exchanges, educational programs, in countries all over the world, especially the developing world in places and in ways that the United States could not.”

Recognition of iconic sites

UNESCO’s most famous totems are its world heritage sites, which include monuments that have weathered long stretches of human history. This month, a massive heat wave forced authorities in Athens to close the Acropolis, a massive edifice that has loomed over the Greek capital for three millennia.

Simmering ethnic conflict in Ethiopia in recent years has hampered religious pilgrims’ access to the massive, ancient rock-hewn churches of Lalibela, a mountain town known in the 13th century as ‘New Jerusalem.’

And the COVID pandemic has kept footfalls light on China’s great Great Wall, the massive fortification whose construction began in the 3rd Century B.C. and UNESCO estimates once boasted a total length of 20,000 kilometers.

This year, UNESCO added another entry to its vaunted list: the historic center of the bustling Ukrainian port city of Odesa, a critical port for Ukraine’s agricultural exports.

This month, a Russian airstrike tore through the city, dropping a missile through the roof of its soaring cathedral and shattering the altar.

UNESCO issued a condemnation.

“On this night alone in Odesa, nearly 50 buildings were damaged, 25 of them architectural monuments,” said Ukrainian president Volodymyr Zelenskyy. “The historic center. A world heritage site that UNESCO has taken under its protection.”

Since Russia invaded Ukraine in 2022, UNESCO has verified damage to 270 of its designated “cultural sites” in Ukraine.

The heavy responsibility of carrying all this cultural weight is lighter now that the U.S. is back, said UNESCO’s director-general, Audrey Azoulay.

“In these times of division, rifts and existential threats to humanity, we reaffirm here and today our union,” she said. “The star-spangled banner of the United States of America will float in a few moments over the Paris skies.”
