knowledge

GYEONGJU, South Korea — The United States will share closely held technology to allow South Korea to build a nuclear-powered submarine, President Trump said on social media Thursday after meeting with the country’s president.

President Lee Jae Myung stressed to Trump in their Wednesday meeting that the goal was to modernize the alliance with the U.S., noting plans to increase military spending to reduce the financial burden on America. The South Korean leader said there might have been a misunderstanding when they last spoke in August about nuclear-powered submarines, saying that his government was looking for nuclear fuel rather than weapons.

Lee said that if South Korea was equipped with nuclear-powered submarines, that it could help U.S. activities in the region.

U.S. nuclear submarine technology is widely regarded as some of the most sensitive and highly guarded technology the military possesses. The U.S. has been incredibly protective of that knowledge, and even a recently announced deal with close allies the United Kingdom and Australia to help the latter acquire nuclear submarine technology doesn’t feature the U.S. directly transferring its knowledge.

Trump’s post on social media comes ahead of his meeting with Chinese President Xi Jinping, whose country possesses nuclear submarines, and after North Korea in March unveiled for the first time a nuclear-powered submarine under construction. It’s a weapons system that can pose a major security threat to South Korea and the U.S.

As Trump visited South Korea, North Korea said Wednesday it conducted successful cruise missile tests, the latest display of its growing military capabilities.

Pentagon officials didn’t immediately respond to questions about Trump’s announcement on sharing the nuclear sub technology with South Korea.

NEW YORK — When Lindsey Vonn retired from Alpine skiing in 2019, she walked away from the sport as one of the most successful skiers in history. Six years later she’s coming back, with her sights set on competing in a fifth Winter Olympics in February in Cortina d’Ampezzo, Italy.

But regardless of how that comeback ends, Vonn isn’t worried about it detracting from what she’s already accomplished.

“This is different because I had nothing to prove,” said Vonn, 41, who climbed a World Cup podium for the first time since 2019 when she finished second at the super-G season finals in Sun Valley, Idaho, last March.

“I don’t think anyone remembers Michael Jordan’s comeback. I don’t think that’s part of his legacy at all,” she continued. “I’ve already succeeded. I’ve already won. I was on the podium. I have the record for the oldest medalist in World Cup by seven years [she set the previous record in 2019]. I feel like this journey has been incredible.”

Vonn has three Olympic medals, but she won her only gold 15 years ago. She’s won eight World Championship medals, but just one since 2017; her last gold came in 2009. But the comeback isn’t so much about rekindling that past as it is about shoring up the present.

“I closed my career, and I definitely would like to close that chapter in maybe a better way than I did in 2019,” said Vonn, who was speaking Tuesday at the U.S. Olympic Committee’s Media Summit in Manhattan. “I feel like I am happy, free. I’m doing it because I love it. I’m not doing to prove anything to anyone.”

Vonn missed the 2014 Winter Games with a right knee injury, an injury that led to her retirement in 2019. But after partial knee-replacement surgery last year, she decided she wasn’t done with skiing yet.

“After the replacement, I knew things were really different,” she said. “My body felt so good, and I just kind of kept pushing myself further and further to see what I was capable of. Skiing and racing seemed like the logical next step.”

She’s a different skiier than she was when first started competing internationally two decades ago, she said.

“I have a lot more perspective now, having been away from the sport for six years,” she said. “That just allows me to compete in a different way and I think that gives me an advantage actually.

“Downhill skiing has a lot to do with with accumulated knowledge. And I’ve obviously accumulated a lot of knowledge, because I’ve raced for a very long time.”

Vonn, whose comeback landed her on the cover of this week’s Time magazine, said she’s in the best shape of her career. But she still must earn enough points on this winter’s World Cup circuit to qualify for the Olympics.

She said she probably wouldn’t have considered racing at a top level again if next February’s Games weren’t schedule for Cortina, where’s won a record 12 career World Cup races. She also recorded her first of 138 World Cup podiums in Cortina in 2004.

“My goal has always been Cortina again. It’s such a special place for me,” she said.

“I didn’t want to set that as a goal, because I didn’t know if I would even be able to compete, let alone qualify or finish the season. Once I trained more and I got in better shape, I said to myself that this is an attainable goal. I can do this.”

And if she can’t, that won’t detract from the fact that she tried. Or from what she’s already accomplished.

“I’m at peace with where I am in my life,” she said. “I don’t need to be ski racing, but I definitely love to ski race and have nothing to prove. So I don’t feel like I have a lot of pressure, even though my dad says it’s the most pressure I’ve ever had in my whole life.”

WASHINGTON — House Republicans on Tuesday unveiled their long-promised report on former President Biden’s use of the autopen, delivering a blistering critique of his time in office and inner circle that largely rehashes public information while making sweeping accusations about the workings of his White House.

The GOP report does not include any concrete evidence that aides conspired to enact policies without Biden’s knowledge or that the president was unaware of laws, pardons or executive orders signed in his name. But Republicans said their findings cast doubt on all of Biden’s actions in office. They sent a letter to Attorney General Pam Bondi urging a full investigation. President Trump ordered a similar inquiry earlier this year.

At its core, the report advances contested claims that Biden’s mental state declined to a degree that allowed White House officials to enact policies without his knowledge. It focuses heavily on the pardons he granted in office, including to his son, Hunter Biden, based on depositions with close Biden aides.

“The cost of the scheme to hide the fallout of President Biden’s diminished physical and mental acuity was great but will likely never be fully calculated,” the report reads. “The cover-up put American national security at risk and the nation’s trust in its leaders in jeopardy.”

Biden has strenuously denied he was unaware of his administration’s actions, calling such claims “ridiculous and false.” Democrats on the House Oversight committee denounced the probe as a distraction and waste of time.

Republicans are shifting attention back to Biden at a tumultuous time, 10 months into Trump’s presidency, with the government shut down and Congress at a standstill over legislation to fund it. House Speaker Mike Johnson, R-La., has kept the House out of session for nearly a month, with most public-facing committee work grinding to a halt.

The report on Biden was largely compiled over several months before the shutdown began. Based on interviews with more than a dozen members of Biden’s inner circle, the report offers few new revelations, instead drawing broad conclusions from unanswered questions.

It includes repeated references to polls of Biden’s approval rating and perceptions of his public gaffes and apparent aging, much of it publicly known.

It alleges a “cover-up of the president’s cognitive decline” orchestrated by Biden’s inner circle and takes particular aim at Biden’s doctor, Kevin O’Connor, who invoked his Fifth Amendment right against testifying. Republicans also singled out senior aides Anthony Bernal and Annie Tomasini, who similarly pleaded the Fifth. All three “should face further scrutiny” from the Justice Department, Republicans said.

Republicans also sent a letter to the D.C. Board of Medicine urging that O’Connor face “discipline, sanction or revocation of his medical license” and “be barred from the practice of medicine in the District of Columbia.”

The report does not include full transcripts of the at-times multiple hours of recorded testimony that witnesses delivered before the committee. It repeatedly scolds Biden officials and Democratic allies for defending Biden’s mental state.

“The inner-most circle, or cocoon, of the White House senior staff organized one of the largest scandals in American history — hiding a cognitively failing president and refusing any means of confirmation of such demise,” the report says.

While the report claims that record-keeping policies in the Biden White House “were so lax that the chain of custody for a given decision is difficult or impossible to establish,” Republicans do not offer any concrete instances of the chain of command being violated or a policy being enacted without Biden’s knowledge.

Still, Republicans argue that Biden’s use of the autopen should be considered invalid unless there is documented proof of him approving a decision.

“Barring evidence of executive actions taken during the Biden presidency showing that President Biden indeed took a particular executive action, the committee deems those actions taken through use of the autopen as void,” the report says.

Democrats and legal experts have warned that broad scrutiny of executive actions could pose future legal headaches for the Trump administration and congressional Republicans, who also often enact policies directed by lawmakers through devices like the presidential autopen.

Skardu, Pakistan – When Wasiyat Khan was woken up by a loud explosion in the middle of the night, he thought “the mountains had burst” and a landslide was on its way.

Accompanied by his family, Wasiyat, a shepherd from Roshan valley of Ghizer, in northern Pakistan’s mountainous Gilgit-Baltistan region, had taken his livestock to elevated land for grazing on a sojourn during the warmer months.

Soon enough, as the family sought immediate safety, he realised the explosion was the sound of a glacier bursting. As their temporary accommodation was being swept away by the floodwaters, Wasiyat thought of the villages which lay in the water’s path.

At more than 3,000 metres in the darkness of the night, outside help was impossible to get. He immediately jumped across boulders and reached a designated spot where he could get mobile phone signals and alerted the villagers, who numbered about 300.

“Within 30 minutes, we got a call back saying the villagers had evacuated safely and no lives were lost,” Wasiyat told local media. “While they were safe, we were left with nothing, not even a matchstick to keep us warm near the glaciers. It was very cold and we were suffering.

“When we were rescued hours later and taken back to the village, we found out that all our houses and land were covered by mud, but no lives were lost.”

The glacial lake outburst flood (GLOF) is a common occurrence in northern Pakistan, home to an estimated 13,000 glaciers. As global warming worsens, the effect of more glaciers melting is “likely to be significant” this year, Pakistan’s disaster management authority, NDMA, had said in March.

In its latest assessment, the NDMA says snowfall across Pakistan in the coming months is projected to be less than average, particularly in areas like Gilgit-Baltistan, reducing overall snow accumulation. A reduced snow cover, it fears, would accelerate glacier retreat by exposing ice earlier in the season, making high-altitude regions more vulnerable to GLOFs.

To prevent such occurrences, the government mainly relies on its early warning systems (EWS), which help in reducing loss of life and injury, economic losses, protecting critical infrastructure, and enhancing climate resilience. 

An EWS functions through an interconnected process made up of sensors and gauges that collect real-time data monitored by meteorologists and experts to not only warn of a current hazard, but also predict a disaster. Dozens of EWS sites across the most climate-vulnerable valleys in Gilgit-Baltistan and Khyber Pakhtunkhwa are currently transmitting real-time data to the Pakistan Meteorological Department.

‘Human EWS’

But residents in northern Pakistan say they are more reliant on Indigenous human knowledge instead of the EWS technology.

Mohammad Hussain, a shepherd in Gilgit-Baltistan’s Skardu Valley, told Al Jazeera about an incident when he was inside his stone hut during the summer. After nearly an hour of rainfall, he witnessed strong lightning followed by an unusual roaring sound.

As he stepped out of the hut to gather his cattle, he saw a powerful flash flood, carrying enormous boulders and uprooting large trees. Acting quickly, he alerted the villagers, which ensured safe evacuation before the floodwaters reached.

He recounted stories shared by his grandfather, who said people relied on large signal fires, gunfire or specific sound patterns to alert others. Natural signs such as sudden heavy rainfall, cloud formations, unusual animal behaviour, and distinct roaring sounds are still being used to predict flash floods in the absence of the EWS.

In one incident, he attempted to light a fire to alert villagers below, but, due to daylight and heavy rain, it was ineffective. He then fired his gun three times, a pre-agreed signal indicating danger. Villagers who heard the gunfire raised alarms through the mosque’s loudspeaker, initiating a rapid evacuation.

Although there were significant economic losses, there were no casualties, demonstrating the effectiveness of this “human EWS”.

Pakistan ranks among the top 10 most climate-vulnerable nations, even though it contributes less than 1 percent of global emissions. The World Bank said in 2023 that the mean temperature in Pakistan since the 1950s has risen by 1.3 degrees Celsius (2.34 degrees Fahrenheit), which is twice as fast as the global mean change.

The country’s climate change minister, Musadiq Malik, recently told Al Jazeera that “when these [glacial] floods hit, they cause immense mortality, morbidity and widespread displacement,” adding that “it’s a harsh reality we face.” Pakistan faced nearly 90 such floods between 2019 and 2022.

‘Technology alone won’t save lives’

Despite spending millions on EWS and its implementation, there has been widespread lack of trust placed in it by a number of communities, due to frequent reports of malfunctioning of equipment and lack of follow-ups by the concerned agencies.

A report in Pakistan’s Friday Times in June this year said “despite launching the $37m GLOF-II project in 2017, with new gauges, sirens, and local training, no real-time link connects human sensors in villages to official rescue teams.”

The report warned that “technology alone won’t save lives if SOPs sit buried, rescue checklists gather dust, and trust is missing on the ground.”

Some villagers Al Jazeera spoke to in Gilgit-Baltistan echoed that sentiment, speaking of their lack of trust in the equipment, questioning its effectiveness, and sharing concerns that these systems have not worked. They also slammed officials for falsely taking credit for the system’s effectiveness in saving lives.

“Residents say the EWS in Gilgit-Baltistan have been installed without taking the local authorities and communities into confidence, which was the reason they could not play an effective role,” Zaki Abbas, an Islamabad-based journalist who writes on climate change, told Al Jazeera.

“Last year, I was told by a local activist that up to 20 systems had been installed at various spots, but they had not been operational for different reasons. This controversy surrounding this issue had also echoed in the GB legislative assembly, with the opposition leaders in the region most recently demanding an investigation into the failure of these systems. However, no such probe was ordered.

“Their ineffectiveness can be gauged by the fact that warnings about GLOFs have come from people, most recently a shepherd whose timely call saved an entire village, instead of these systems on which billions of rupees have been spent.”

Addressing the challenges remains a task for the government and partners involved in the implementation of EWS. The UNDP said in February this year that “limited financial resources, technical capacity, data gaps and uncertainties, communication barriers, weak institutional capacities, and complex and evolving climate risks” are just some of the issues facing EWS globally.

When Wasiyat and two other shepherds from Ghizer were given $28,000 each in August by Pakistan’s prime minister as rewards for saving hundreds of lives, they were told that “this act of courage and responsibility will be written in golden words.”

As unpredictable rains, snow patterns and melting glaciers continue to affect Pakistan, especially the northern areas, it seems residents are more likely to rely on these “heroes” in the absence of widespread EWS and the community’s trust in them.
