Day: July 19, 2023

Italy put 23 cities on red alert as it reckoned with another day of scorching temperatures Wednesday, with no sign of relief from the wave of extreme heat, wildfires and flooding that has wreaked havoc from the United States to China.

The heat wave has hit southern Europe during the peak summer tourist season, breaking records – including in Rome – and bringing warnings about an increased risk of deaths.

Wildfires burned for a third day west of the Greek capital, Athens, and firefighters raced to keep flames away from coastal refineries.

Fanned by erratic winds, the fires have gutted dozens of homes, forced hundreds of people to flee and blanketed the area in thick smoke. Temperatures could climb to 109 Fahrenheit on Thursday, forecasters said.

Extreme weather was also disrupting life for millions of Americans. A dangerous heat wave was holding an area stretching from Southern California to the Deep South in its grip, bringing the city of Phoenix its 20th straight day with temperatures of 110 degrees Fahrenheit or higher.

Meanwhile, Tropical Storm Calvin lashed Hawaii, raising the potential for flash flooding and dangerous surf on the Big Island.

In Texas, at least nine inmates in prisons without air conditioning have suffered fatal heart attacks during the extreme heat this summer, the Texas Tribune newspaper reported.

Another 14 have died of unknown causes during periods of extreme heat.

A Texas Department of Criminal Justice spokesperson said preliminary findings of the deaths indicate that heat was not a factor in the fatalities. Nearly 70 of the 100 prisons in Texas are not fully air-conditioned.

Temperatures soar in China, Italy

In China, which was hosting U.S. climate envoy John Kerry for talks, tourists defied the heat to visit a giant thermometer showing surface temperatures of 80 Celsius (176 Fahrenheit).

In Beijing, which set a record as temperatures remained above 95 Fahrenheit for the 28th consecutive day, Kerry expressed hope that cooperation to combat global warming could redefine troubled ties between the two superpowers, both among the top polluters.

Temperatures remained high across much of Italy on Wednesday, where the health ministry said it would activate an information hotline and teams of mobile health workers visited the elderly in Rome.

“These people are afraid they won’t make it, they are afraid they can’t go out,” said Claudio Consoli, a doctor and director of a health unit.

Carmaker Stellantis said it was monitoring the situation at its Pomigliano plant near Naples on Wednesday, after temporarily halting work on one production line the day before when temperatures peaked.

Workers at battery-maker Magneti Marelli threatened an eight-hour strike at their central Italian plant in Sulmona. A joint statement by the unions said that “asphyxiating heat is putting at risk the lives of workers.”

While the heat wave appears to be subsiding in Spain, residents in Greece were left surveying the wreckage of their homes after the wildfires.

Scientists have long warned that climate change, caused by greenhouse gas emissions mainly from burning fossil fuels, will make heat waves more frequent, severe and deadly and have called on governments to drastically reduce emissions.

In Germany, the heat wave sparked a discussion on whether workplaces should introduce siestas for workers.

Heat and floods in Asia

In South Korea, heavy rain has pummeled central and southern regions since last week. Fourteen deaths occurred in an underpass in the city of Cheongju, where more than a dozen vehicles were submerged on Saturday when a river levee collapsed. In the southeastern province of North Gyeongsang, 22 people died, many from landslides and swirling torrents.

In northern India, flash floods, landslides and accidents related to heavy rainfall have killed more than 100 people since the onset of the monsoon season on June 1, where rainfall is 41% above average.

The Yamuna River reached the compound walls of the Taj Mahal in Agra for the first time in 45 years, submerging several other historical monuments, and flooded parts of the Indian capital.

The Brahmaputra River, which runs through India’s Assam state, burst its banks this month, engulfing almost half of the Kaziranga National Park – home to the rare one-horned rhino – in waist-deep water.

A wall collapse from monsoon rains killed at least 11 construction workers in neighboring Pakistan.

Iraq’s southern Basra governorate, with a population of around 4 million, said government work would be suspended on Thursday as temperatures hit 122 Fahrenheit. In Iraq’s northern city of Mosul, farmers said crops were failing because of heat and drought.

The unprecedented temperatures have added new urgency for nations around the globe to tackle climate change. With the world’s two biggest economies at odds over issues ranging from trade to Taiwan, Kerry told Chinese Vice President Han Zheng on Wednesday that climate change must be handled separately from broader diplomatic issues.

“It is a universal threat to everybody on the planet and requires the largest nations in the world, the largest economies in the world, the largest emitters in the world, to come together in order to do work not just for ourselves, but for all mankind,” Kerry told Han.

People who have a particular genetic variant are twice as likely to never feel sick when they contract COVID-19, researchers said Wednesday, offering the first potential explanation for the lucky group dubbed the “super dodgers.”

Those who have two copies of the variant are eight times more likely to never get any symptoms from COVID-19, according to the study in the journal Nature.

Previous research has suggested that at least 20% of the millions of infections during the pandemic were asymptomatic. To find out what could be behind these cases, researchers took advantage of a database of volunteer bone marrow donors in the United States.

The database included each person’s type of human leukocyte antigen (HLA), which are molecules on the surface of most cells in the body. The immune system uses HLA to see which cells belong in the body, and they are thought to play a key role in the response to viral infections.

Subjects self-reported symptoms

The researchers had nearly 30,000 people on the bone marrow registry self-report their COVID tests and symptoms on a mobile phone app.

More than 1,400 unvaccinated people tested positive for COVID between February 2020 and late April 2021, the study said. Out of that group, 136 saw no symptoms two weeks before and after testing positive. 

One in five of that group carried at least one copy of an HLA variant called HLA-B*15:01.

Those fortunate enough to have two copies of the gene, one from their mother and one from their father, were more than eight times more likely to be asymptomatic from COVID-91 than other people, the study said.

To find out why this was the case, the team carried out separate research looking at T cells, which protect the body from infections, in people who carried the variant. The researchers specifically looked at how T cells remembered viruses they had previously encountered.

This meant they were “armed and ready for attack when they encounter the same pathogen again,” said Jill Hollenbach of the University of California, San Francisco, who was the study’s lead researcher.

When people with the HLA variant were exposed to the coronavirus, their T cells were particularly primed for battle because they remembered similar cold viruses they had previously fended off.

Children often spared the worst

This theory — that recent exposure to colds and other coronaviruses could lead to fewer COVID symptoms — has previously been proposed to explain why children have often been spared the worst of COVID.

“Anyone that has ever been a parent knows that kids are snotty-nosed for five or six years, so I think that’s a really reasonable thing to speculate might be happening,” Hollenbach said.

She said the HLA variant was likely just one piece of the genetic puzzle behind asymptomatic COVID.

The researchers hope that studying the immune response to COVID could lead to new treatments or vaccines in the future. Hollenbach said one interesting idea was a vaccine that prevents COVID symptoms, as opposed to infection, which could potentially last longer than the currently available vaccines.

The researchers warned that most of the study’s participants were white, which could limit the findings for other groups, and that it covered an earlier period of the pandemic and did not include re-infections.

Childhood immunization has rebounded following a significant decline during the early years of the COVID-19 pandemic, but at an uneven rate with too many children in low-income countries still missing out on the life-saving products, according to a joint World Health Organization-UNICEF report.

The agencies say that four million more children were immunized against killer diseases in 2022 compared to the previous year.

“Last year, we rang alarm bells at the historic backsliding that we saw across countries, regions, and vaccines,” said Kate O’Brien, director, immunization, vaccines, and biologicals, WHO.

“From 2022’s data, from a global perspective, we are recovering,” she said. “But that recovery is uneven, with too many countries not yet seeing improvement.”

The report says that just eight large countries—India, Indonesia, Myanmar, Philippines, Brazil, Mexico, Pakistan, and Tanzania—account for 3.8 million of the four million additional children reached in 2022.

Of the 73 countries that recorded substantial declines of more than five percent during the pandemic, the report says “24 are on route to recovery and, most concerningly, 34 have stagnated or continued declining.”

O’Brien said a main measure of immunization program performance is how many zero-dose children exist.

“These are children who do not receive a first dose of the vaccine against diphtheria, tetanus, and pertussis. It means these are children who do not receive any vaccine through the routine immunization program.”

The good news, she said, is that global coverage of the first dose of DTP vaccine now stands at 89 percent—very close to the pre-pandemic coverage of 90 percent.

However, she noted that the data is a lot more nuanced when looked at by region and income.

“All regions, except for the Africa region, have made progress in recovery for DTP. The region’s coverage is now six percent lower than 2019 levels and this is the largest gap for any region,” she said.

The report finds some backsliding in measles vaccine coverage as well, noting that only 83 percent of children globally were vaccinated against that killer disease in 2022, below pre-pandemic levels of 86 percent.

“Fifty-nine countries reported a total of 80 measles outbreaks in 2022,” said Ephrem Tekle Lemango, UNICEF associate director of immunization.

“Since coverage levels declined, we have witnessed outbreaks of diseases such as measles, yellow fever and diphtheria increasing, and our efforts to eradicate polio have been set back,” he said.

“If we do not catch-up vaccinations of older children that were missed since 2019, quickly and urgently,” he warned, “we will inevitably witness more outbreaks and be responsible for more child deaths.”

The WHO’s Kate O’Brien expressed the urgency of vaccinating children against measles in low-income countries, noting that someone who is not immune to the disease could infect between 12 and 20 other people.

“The way children become immune is best done by vaccination, not by actually getting infected and risking severe disease or death or other consequences from measles,” she said.

Ephrem Lemango said reaching children on the African continent, which is home to 12 percent of the world’s population, is particularly challenging as “It is home to 54 percent of the un- or under-vaccinated children,” a significant proportion of whom remain unreached.

“This is because they are facing other challenges, such as conflict and crises,” he said, “but also because, over many years, they have not had the resources to build resilient health systems.”

O’Brien said the overarching, dominant reason why children do not get vaccinated is lack of access. She said families in remote, rural areas in particular have difficulty reaching a clinic where vaccines are administered.

However, she added that “We are very concerned about vaccine confidence and the awareness of families around the benefit of vaccines.

“And clearly, the information and misinformation and disinformation that is growing in size and growing in scope is having some impact in some communities at specific times on the confidence that people have in vaccines.”

Artificial intelligence is quickly becoming part of our social media world on our cellphones and computers. Text, images, audio and video are becoming easier for anyone to create using new generative AI tools.

As AI-generated materials become more pervasive, it’s getting harder to tell the difference between what is real and what has been manipulated.

“It’s one of the challenges over the next decade,” said Kristian Hammond, a professor of computer science who focuses on artificial intelligence at Northwestern University.

AI-generated content is making its way into movies, TV shows and social media on Facebook, TikTok, Snapchat and other platforms.

AI has been used to change images of former President Donald Trump and Pope Francis. The winner of a prestigious international photo competition this year used AI to create a fake photo.

Victor Lee, who specializes in AI as an associate professor in the Graduate School of Education at Stanford University, said, “people need to exercise caution when looking at AI-generated materials.”

Whether it’s text, video, an image or audio, with generative AI we are seeing things that look like actual news or an image of a particular person but it’s not true, Lee said.

AI is also being used to create songs that sound like popular musical artists and replicating images of actors.

Recently, an anonymous person on TikTok used artificial intelligence to create a song with a beat, lyrics and voices that fooled many people into believing it was a recording by pop stars Drake and The Weeknd.

Among the demands of television and film actors and writers currently on strike in the U.S. are protections against the use of AI, which has advanced to replicate faces, bodies and voices on movies and TV.

“I think the Avatar movies have been so successful because people were able to identify with the animation of the simulated characters,” said Bernie Luskin, director of the Luskin community college leadership initiative at the University of California, Los Angeles.

Luskin, who does research on media psychology, thinks that as the use of AI becomes a worldwide phenomenon, it will affect people psychologically and influence their behavior.

“It’s definitely going to have a dramatic impact on social media,” he said. “As AI becomes more common, it will become increasingly deceptive, and abusers will abuse it.”

On a positive note, Hammond said AI will promote additional artistic elements.

“We’re going to have a new view of what it means to be creative,” he said, “and there will be a different kind of appreciation because the AI systems are generating things in partnership with a human.”

A major concern, however, is that people are already being duped by AI, and as the technology becomes even more sophisticated, it will be even more difficult to discern its imprint.

Krishnan Vasudevan, assistant professor in visual communication at the University of Maryland, worries that people may become immune to AI-generated materials and won’t care if they are real or not.

“They’ll be wanting visuals that reinforce their viewpoints, and they’ll use the tool as a way to discredit or make fun of political opponents,” he said.

Experts say norms, regulations and guardrails must be considered to keep AI in line.

“Does AI receive credit as a co-author?” Lee asked.

“I think there will be legal battles about using somebody’s voice or likeness,” Vasudevan said.

“We have to start looking hard at exactly what is going out there,” said Hammond. “For example, there should be regulations that say your image should not be associated with anything pornographic.”

Lee said artificial intelligence will create big changes the public will get used to, much like the Internet and social media have done.

“The Internet is not inherently a good or bad thing, but it changed society,” he said. “AI is also not good or bad, and it is going to do something similar.”

Chinese livestreamers have set their sights on TikTok shoppers in the U.S. and Europe, hawking everything from bags and apparel to crystals with their eyes on a potentially lucrative market, despite uncertainties over the platform’s future in the U.S. and elsewhere.

In China, where livestreaming ecommerce is forecast to reach 4.9 trillion yuan ($676 billion) by the year’s end, popular hosts like “Lipstick King” Austin Li rack up tens of millions of dollars in sales during a single livestream. Many brands, including L’Oreal, Nike and Louis Vuitton, have begun using livestreaming to reach more shoppers.

But the highly competitive livestreaming market in China has led some hosts to look to Western markets to carve out niches for themselves.

Oreo Deng, a former English tutor, sells jewelry to U.S. customers by livestreaming on TikTok, delivering her sales pitches in English for about four to six hours a day.

“I wanted to try livestreaming on TikTok because it aligned with my experiences as an English tutor and my past jobs working in cross-border e-commerce,” Deng said.

Since 2019, western e-commerce platforms like Amazon and Facebook have experimented with livestreaming e-commerce after seeing the success of Chinese platforms like Alibaba’s Tmall and Taobao, and Douyin, TikTok’s Chinese counterpart in China.

TikTok started testing its live shopping feature last year. Registered merchants from the U.S., Indonesia, Vietnam and Singapore, among other countries, can now sell via livestreams online.

But livestreaming e-commerce has yet to take off in the U.S. The livestreaming e-commerce market in the U.S. — the world’s biggest consumer market — is expected to grow to $68 billion by 2026, according to research and advisory firm Coresight Research.

The relatively lukewarm reception led Facebook to shut down its live shopping feature last year. As for TikTok, the platform has the added risk of potentially facing U.S. restrictions due to tensions between Beijing and Washington.

TikTok, whose parent company is Chinese technology firm ByteDance, has been criticized for its Chinese ties and accused of being a national security risk due to the data it collects.

TikTok did not provide comment for this story.

Despite the scrutiny faced by TikTok, many Chinese hosts view the U.S. as a vast ocean of opportunity, an emerging market that has yet to be saturated with livestreaming hosts.

“There’s more opportunity for growth to target America because the competition is so fierce in China,” said Shaun Rein, founder and managing director of China Market Research Group in Shanghai. “Livestreaming in the U.S. is at a beginning starting point. There’s more opportunity to grab market share.”

Rein also said that Chinese merchants can often price items higher in the U.S., where customers are accustomed to paying higher prices compared to in China, where product margins are often razor-thin.

“The format is going to work, because it’s been proven,” said Jacob Cooke, CEO of e-commerce consultancy WPIC.

Smaller companies, including those in China that are attempting to sell on TikTok, might lack enough data on what customers want in markets like the U.S, he said. “Once they do get that figured out, they’ll start to have very good success,” Cooke said.

For some U.S. shoppers, the livestream format is a fascinating form of entertainment.

Freisa Weaver, a 36-year-old who lives in Florida, stumbled on a TikTok livestream selling crystals 10 months ago. It employed a popular tactic called a “lucky scoop” where buyers pay a set price to receive several random items scooped from a large container of crystals. TikTok earlier this year banned this practice from livestreams to comply with gambling laws, although some sellers still offer grab bags of goodies which appear to be scooped off-camera.

“I came across it scrolling through TikTok and at first I was entertained by the lucky scoops,” Weaver said, describing livestreaming shopping as an addictive hobby. “Now I’m a regular buyer in some of the live feeds on TikTok.”

“I personally enjoy the interactions with the host and the possibility of finding something special and unique just for me,” she said

Her favorite channel is Meow Crystals, an account operated by Chinese streaming hosts that often does flash sales selling crystals for as little as $2, and grab bags of crystals from $10. TikTok has yet to roll out its in-built shopping feature on a wide scale, so many streamers, including those from Meow Crystals, often redirect viewers to place orders on an external website.

“The host is willing to go to the warehouse for you and get special items, or they remember what you like and offer it to you as soon as you are online,” Weaver said.

Chinese livestreaming hosts try various tactics to stand out and build a loyal customer base. For some, it’s personalized customer service, while others use quirky catchphrases and concoct flamboyant online personalities to keep their customers entertained.

“Every host is always experimenting and develops their own tactics,” Deng, the livestream host said, declining to share the secrets of her own approach.

Boot camps to teach Chinese livestreamers how to increase their sales have sprung up, including a popular one hosted by Yan Guanghua, one of TikTok earliest livestreamers in China.

Like Deng, Yan is a former English tutor who turned to TikTok livestreaming after a government crackdown on the private education industry.

Yan started out hawking yoga clothes, electronics and apparel online. Finding she had a knack for selling to customers via livestreaming, she at times has racked up sales of 5,000 pounds ($6,510) per stream selling to customers in Britain.

Now she charges about $1,000 for two-day boot camps she holds two or three times a month, teaching people how to sell more on livestreams.

Yan says she has trained more than 600 people, mostly from China but also from the U.S. and Africa.

Like many other TikTok livestreaming hosts, she hopes the overseas livestreaming e-commerce market will take off like it has in China.

“It’s hard to say what the future of this industry is. It’s difficult to predict,” Yan said. “But what we know is that TikTok is the most popular platform right now and there is still opportunity here.”

Climate change is a “universal threat” that should be handled separately from broader diplomatic issues, U.S. climate envoy John Kerry told Chinese Vice-President Han Zheng on Wednesday after two days of what he called constructive but complex talks. 

Acknowledging the diplomatic difficulties between the two sides in recent years, Kerry said climate should be treated as a “free-standing” challenge that requires the collective efforts of the world’s largest economies to resolve.  

“We have the ability to … make a difference with respect to climate,” he said at a meeting at Beijing’s Great Hall of the People, China’s sprawling parliament building. 

Kerry arrived in Beijing on Sunday as heat waves scorched parts of Europe, Asia and the United States, underscoring the need for governments to take drastic action to reduce carbon emissions, which contribute to global warming and extreme weather events. 

He has held meetings with China’s top diplomat Wang Yi and Premier Li Qiang as well as veteran climate envoy Xie Zhenhua in a bid to rebuild trust between the two sides ahead of COP28 climate talks in Dubai at the end of the year.  

“If we can come together over these next months leading up to COP28, which will be the most important since Paris, we will have an opportunity to be able to make a profound difference on this issue,” he told Han.  

Han said the two countries had maintained close communication and dialog on climate since Kerry’s appointment as envoy, adding that a joint statement issued by the two sides has sent a “positive signal” to the world.  

Kerry told reporters earlier that his talks with Chinese officials this week have been constructive but complicated, with the two sides still dealing with political “externalities,” including Taiwan. 

“We’re just reconnecting,” he said. “We’re trying to re-establish the process we have worked on for years.” 

“We’re trying to carve out a very clear path to the COP to be able to cooperate and work as we have wanted to with all the externalities,” Kerry said.  

Climate diplomacy between the world’s top two emitters was suspended in August last year following the visit of U.S. House of Representatives Speaker Nancy Pelosi to Taiwan, a democratically governed island that China claims. 

“The mood is very, very positive,” Kerry said ahead of Wednesday’s meetings. “We had a terrific dinner last night. We had a lot of back and forth. It’s really constructive.” 

“We’re focused on the substance of what we can really work on and what we can make happen.”
