China Reports 10,000 New Virus Cases; Capital Closes Parks

Beijing closed city parks and imposed other restrictions as the country faces a new wave of COVID-19 cases, even as millions of people remained under lockdown Friday in the west and south of China.

The country reported 10,729 new cases on Friday, almost all of them testing positive while showing no symptoms. More than 5 million people were under lockdown Friday in the southern manufacturing hub Guangzhou and the western megacity Chongqing.

With the bulk of Beijing’s 21 million people undergoing near daily testing, another 118 new cases were recorded in the sprawling city. Many city schools switched to online classes, hospitals restricted services and some shops and restaurants were shuttered, with their staff taken to quarantine. Videos on social media showed people in some areas protesting or fighting with police and health workers.

“It has become normal, just like eating and sleeping,” said food service worker Yang Zheng, 39. “I think what it impacts most is kids because they need to go to school.”

Demands for testing every 24-48 hours are “troublesome,” said Ying Yiyang, who works in marketing.

“My life is for sure not comparable to what it was three years ago,” said Ying. Family visits outside of Beijing can be difficult if the smartphone app that virtually all Chinese are required to display does not green-light travel back to the capital, Ying said.

“I just stay in Beijing,” Ying said.

Numerous villages on the capital’s outskirts that are home to blue-collar workers whose labor keeps the city running were under lockdown. Many live in dormitory communities, which taxi and ride-sharing drivers said they were avoiding so as not to be placed in quarantine themselves.

Lockdowns in Guangzhou and elsewhere were due to end by Sunday, but authorities have repeatedly extended such restrictions with no explanation.

Chinese leaders had promised Thursday to respond to public frustration over its severe “zero-COVID” strategy that has confined millions to their homes and severely disrupted the economy.

The government said Friday it was reducing the amount of time incoming passengers would be required to undergo quarantine. The U.S. embassy this week renewed its advisement for citizens to avoid travel to and within China unless absolutely necessary.

Incoming passengers will only be quarantined for five days, rather than the previous seven, at a designated location, followed by three days of isolation at their place of residence, according to a notice from the State Council, China’s Cabinet.

It wasn’t immediately clear when and where the rules would take effect and whether they would apply to foreigners and Chinese citizens alike.

Relaxed standards would also be applied to foreign businesspeople and athletes, in what appeared to be a gradual move toward normalization.

Airlines will no longer be threatened with a two-week-long suspension of flights if five or more passengers tested positive, the regulations said, potentially providing a major expansion of seats on such flights that have shrunk in numbers and soared in price since restrictions were imposed in 2020.

Those flying to China will only need to show a single negative test for the virus within 48 hours of traveling, the rules said. Formerly, two tests within that time period were required.

“Zero-COVID” has kept China’s infection rate relatively low but weighs on the economy and has disrupted life by shutting schools, factories and shops, or sealing neighborhoods without warning. With the new surge in cases, a growing number of areas are shutting down businesses and imposing curbs on movement. In order to enter office buildings, shopping malls and other public places, people are required to show a negative result from a virus test taken as often as once a day.

With economic growth weakening again after rebounding to 3.9% over a year earlier in the three months ending in September, forecasters had been expecting bolder steps toward reopening the country, whose borders remain largely closed.

President and ruling Communist Party leader Xi Jinping is expected to make a rare trip abroad next week, but has given little indication of backing off on a policy the party has closely associated with social stability and the avowed superiority of his policies.

That has been maintained by its seven-person Politburo Standing Committee, which was named in October at a party congress that also expanded Xi’s political dominance by appointing him to a third five-year term as leader. It is packed with his loyalists, including the former party chief of Shanghai, who enforced a draconian lockdown that sparked food shortages, shut factories and confined millions to their homes for two months or more.

People from cities with a single case in the past week are barred from visiting Beijing, while travelers from abroad are required to be quarantined in a hotel for seven to 10 days — if they are able to navigate the timely and opaque process of acquiring a visa.

Business groups say that discourages foreign executives from visiting, which has prompted companies to shift investment plans to other countries. Visits from U.S. officials and lawmakers charged with maintaining the crucial trading relations amid tensions over tariffs, Taiwan and human rights have come to a virtual standstill.

Last week, access to part of the central city of Zhengzhou, home to the world’s biggest iPhone factory, was suspended after residents tested positive for the virus. Thousands of workers jumped fences and hiked along highways to escape the factory run by Taiwan’s Foxconn Technology Group. Many said coworkers who fell ill received no help and working conditions were unsafe.

Also last week, people posted outraged comments on social media after a 3-year-old boy, whose compound in the northwest was under quarantine, died of carbon monoxide poisoning. His father complained that guards who were enforcing the closure refused to help and tried to stop him as he rushed his son to a hospital.

Despite such complaints, Chinese citizens have little say in policy making under the one-party authoritarian system that maintains rigid controls over media and public demonstrations.

Speculation on when measures will be eased has centered on whether the government is willing to import or domestically produce more effective vaccines, with the elderly population left particularly vulnerable.

That could come as soon as next spring, when a new slate of officials are due to be named under Xi’s continuing leadership. Or, restrictions could persist much longer if the government continues to reject the notion of living to learn with a relatively low level of cases that cause far fewer hospitalizations and deaths than when the pandemic was at its height.

Repeat COVID Infections Increase Risk of Health Problems, US Study Finds

People who have had COVID-19 more than once are two or three times more likely to have a range of serious health problems than those who have only had it once, the first major study on the subject said Thursday.

Multiple infections have surged as the pandemic rumbles on and the virus mutates into new strains, but the long-term health effects of reinfection have not been clear.

The U.S. researchers said their new study published in the Nature Medicine journal was the first to look at how reinfection increases the risk of health problems from acute cases as well as long COVID.

The researchers analyzed the anonymous medical records of 5.8 million people in the U.S. Department of Veterans Affairs’ national health care database.

More than 443,000 had tested positive for COVID-19 at least once between March 1, 2020, and April this year.

Nearly 41,000 of that group had COVID more than once. More than 93% had a total of two infections, while 6% had three, and nearly 1% had four.

The other 5.3 million never contracted COVID-19.

When the researchers compared the health outcomes of the different groups, they found that “people who got reinfected have an increased risk of all sorts of adverse health problems,” Ziyad Al-Aly, an epidemiologist at Washington University in St. Louis and the study’s senior author, told AFP.

People with repeat infections were twice as likely to die prematurely and three times more likely to be hospitalized with illness than those who had not been reinfected, the study found.

Heart and lung problems were more than three times more common for people who had been reinfected.

Reinfection also contributes to brain conditions, kidney disease and diabetes, the study said.

And the risk of such problems could increase with each infection, it suggested.

Al-Aly warned that this means that continuous reinfections “would likely elevate the burden of disease in the population.”

Epidemiologist recommends masks

Ahead of a feared COVID-19 spike during the holiday season, he called on people to wear masks to protect themselves.

He also urged authorities to do more to stop the disease from circulating.

“The reason reinfection is happening is that our current vaccine strategy does not block transmission,” he said.

“I think reinfections will continue to happen until we have vaccines that block transmission, offer more durable protection, and are variant proof,” he said.

‘Worrisome’ findings

The authors said the limitations of the study included that most of the veteran participants were older white males.

When the study was released as a preprint in June, U.S. expert Eric Topol described the findings as “worrisome.”

In a Substack post, Topol pointed out that reinfections became “much more common” after April — when the study’s timeframe ended — because of new, more transmissible omicron variants.

China Says It Won’t Pay Into Climate Fund for Developing Countries

China Wednesday said it would not pay into a climate loss and damage fund for developing nations, after small island nations cited its responsibility as a high carbon emitter at the U.N. Climate Change Conference in Egypt, COP27.

Antigua and Barbuda Prime Minister Gaston Browne, on behalf of the Association of Small Island States, Tuesday called for major greenhouse gas emitters China and India to chip in for a fund to compensate poor countries for the consequences of climate change.

It was the first time developing nations have included China and India among countries financially accountable for emissions.

Beijing would support such a mechanism, but would not pay cash into the loss and damage fund, Chinese climate envoy Xie Zhenhua said Wednesday.

Xie added that China does is not obliged to contribute but reiterated the country’s alignment with developing nations in seeking such fund from developed countries.

Despite being the world’s largest greenhouse gas emitter China has long been categorized as a developing nation and is put into the same group with developing countries at COP for climate discussions.

Developing countries have long urged wealthier nations to deliver on promises of $100 billion a year for climate mitigation and adaptation, but rich nations were found to fall short on that pledge, according to an OECD report.

The pressure from developing nations for China to pay for loss and damage reflects a “diluted view” of the argument that historic emitters should pay the most, according to Scott Moore, director of China programs and strategic initiatives at the University of Pennsylvania specializing in environmental sustainability and international relations.

“There is a lot of legitimacy to the historic emissions argument. On the other hand, China, in particular, its emissions growth really just in the last 20, 25 years has been so enormous that its emissions are kind of starting to veer into a territory where you can argue that China is actually responsible for a significant share of cumulative emissions,” Moore told VOA by video call.

Historically, China has contributed to about 13% of the world’s carbon emissions since the start of the industrial revolution, while the United States and the EU account for over 20% each. China, along with the United States, was found to release more carbon than their share of world population – China has 19% of the world’s population, but has produced over one-fourth of the world’s carbon emissions.

China’s shifting role

During COP26, last year’s U.N. climate change conference, in Glasgow, Scotland, China and other developing nations sought $1.3 trillion per year from wealthier nations starting 2030. A report from high-level experts at the United Nations, published this month, said by 2030, $2.4 trillion a year would be but only for developing countries “other than China.” The report also said China, along with Western Europe and North America, has dominated the world’s climate finance.

Beijing has been slowly shifting its role to being a donor country, according to Gørild Merethe Heggelund, research professor at Fridtjof Nansen Institute in Oslo, who focuses on China’s climate change policies.

“China was a recipient of climate finance for years, but China has now become a donor country. Their role as an aid country is becoming stronger and becoming clearer as it goes on and getting more experience,” Heggelund told VOA via a video call.

At COP21 in 2015, Chinese President Xi Jinping established the $3.1 billion South-South Climate Cooperation Fund in a move scientists called “significant,” as it was one of the largest single pledges from developing countries to support climate action. In June this year, Xi injected another $1 billion in the fund that is now named “he Global Development and South-South Cooperation Fund.

The addition is part of Xi’s new 2021 Global Development Initiative, which aims to fund projects in the Global South to boost sustainable development and capacity building. In September, officials said over 1,000 programs are planned under the GDI.

Piqued by internal challenges and geopolitics

China is likely to focus more on domestic mitigation efforts than international contributions, Heggelund said.

“China is highly vulnerable to climate change and we’ve seen some of the droughts this summer. They have some challenges at home that they need to address and that they are addressing. I think we can see a little bit of a difference between what China is doing on the global scene and the negotiations, and what they are doing domestically,” he said.

Despite a 3.9% economic growth in this year’s third quarter, China is expected to have a bumpy road to recovery over its continued COVID-19 lockdown curbs, a global recession and a sluggish property market.

Geopolitics will also inevitably play a role in climate negotiations for China, Moore said. “I think for a long time we had sort of hoped and thought that climate change could be kind of special.”

The United States and China joined hands at COP26 for climate cooperation talks amid political tensions. Part of that agreement included discussions about “scaling up of financial and capacity-building support for adaptation in developing countries.”

However, China suspended the bilateral cooperation in August, following U.S. House or Represenatives Speaker Nancy Pelosi’s visit to Taiwan. Beijing said such climate talks “cannot be separated from the broad climate of bilateral ties.” The two sides held unofficial talks at COP27, but have not confirmed whether they would resume climate cooperation.

“We will see climate change and climate action defined by as much by these geopolitical tensions and issues as anything else,” said Moore.

US Climate Envoy Kerry Launches Carbon Offset Plan

U.S. climate envoy John Kerry on Wednesday announced the creation of a carbon offset plan meant to help developing countries speed their transition away from fossil fuels.

Kerry launched the Energy Transition Accelerator (ETA) with the intention of funding renewable energy projects and accelerating clean energy transitions in developing countries.

The United States will develop the program with the Bezos Earth Fund and Rockefeller Foundation, with input from the public and private sectors which would operate through 2030 and possibly be extended to 2035.

Kerry said Chile and Nigeria were among the developing countries to have shown early interest in the ETA, and that Bank of America, Microsoft, PepsiCo and Standard Chartered Bank had voiced interest in “informing the ETA’s development”.

“Our intention is to put the carbon market to work to deploy capital to speed the transition from dirty to clean power specifically, to retire unabated coal-fired power and accelerate the buildout of renewables,” he said at the event launch on Wednesday. Kerry added that the carbon credits used in the program would be “high quality” and meet “strong safeguards”.

The U.S. climate envoy acknowledged widespread criticism of voluntary carbon offset schemes raised by environmental groups and a task force created by U.N. Secretary General Antonio Guterres, which on Tuesday recommended that carbon credits be used sparingly by companies and governments to avoiding undermining their net-zero emission plans.

Kerry said Guterres was supportive of the U.S.-led carbon market initiative provided there were safeguards to it.

The two had met earlier on Wednesday at the COP27 climate summit in Egypt.

Environmental groups panned the initiative, saying that the scheme would delay real efforts to slash emissions.

“A voluntary carbon credit program won’t guarantee deep, real cuts in emissions – it’s tantamount to rearranging the deck chairs as the climate ship is going down,” said Rachel Cleetus, policy director at the Union of Concerned Scientists.

At the event launch, a protester interrupted Kerry saying: “You’re providing false solutions.”

Kerry responded that fossil fuel companies would not participate in the program.

Facebook Parent Meta Cuts 11,000 Jobs, 13% of Workforce

Facebook parent Meta is laying off 11,000 people, about 13% of its workforce, as it contends with faltering revenue and broader tech industry woes, CEO Mark Zuckerberg said in a letter to employees Wednesday.

The job cuts come just a week after widespread layoffs at Twitter under its new owner, billionaire Elon Musk. There have been numerous job cuts at other tech companies that hired rapidly during the pandemic.

Zuckerberg as well said that he had made the decision to hire aggressively, anticipating rapid growth even after the pandemic ended.

“Unfortunately, this did not play out the way I expected,” Zuckerberg said in a prepared statement. “Not only has online commerce returned to prior trends, but the macroeconomic downturn, increased competition, and ads signal loss have caused our revenue to be much lower than I’d expected. I got this wrong, and I take responsibility for that.”

Meta, like other social media companies, enjoyed a financial boost during the pandemic lockdown era because more people stayed home and scrolled on their phones and computers. But as the lockdowns ended and people started going outside again, revenue growth began to falter.

An economic slowdown and a grim outlook for online advertising — by far Meta’s biggest revenue source — have contributed to Meta’s woes. This summer, Meta posted its first quarterly revenue decline in history, followed by another, bigger decline in the fall.

Some of the pain is company-specific, while some is tied to broader economic and technological forces.

Last week, Twitter laid off about half of its 7,500 employees, part of a chaotic overhaul as Musk took the helm. He tweeted that there was no choice but to cut the jobs “when the company is losing over $4M/day,” though did not provide details about the losses.

Meta has worried investors by pouring over $10 billion a year into the “metaverse” as it shifts its focus away from social media. Zuckerberg predicts the metaverse, an immersive digital universe, will eventually replace smartphones as the primary way people use technology.

Meta and its advertisers are bracing for a potential recession. There’s also the challenge of Apple’s privacy tools, which make it more difficult for social media platforms like Facebook, Instagram and Snap to track people without their consent and target ads to them.

Competition from TikTok is also an a growing threat as younger people flock to the video sharing app over Instagram, which Meta also owns.

“We’ve cut costs across our business, including scaling back budgets, reducing perks, and shrinking our real estate footprint,” Zuckerberg said. ”We’re restructuring teams to increase our efficiency. But these measures alone won’t bring our expenses in line with our revenue growth, so I’ve also made the hard decision to let people go.”

Zuckerberg told employees Wednesday that they will receive an email letting them know if they are among those being let go.

NASA Moon Rocket Launch Delayed Again, This Time by Storm

NASA again rescheduled its long-delayed uncrewed mission to the Moon on Tuesday as Tropical Storm Nicole churned toward the east coast of Florida, officials said.

A launch attempt, which had been scheduled for November 14, will now take place on November 16, Jim Free, a senior official at the U.S. space agency, said on Twitter.

It is the third delay of the highly anticipated launch in as many months.

“Our people are the most important aspect of our mission,” wrote Free, who is NASA’s associate administrator for exploration systems development. “Adjusting our target launch date for #Artemis I prioritizes employee safety and allows our team to tend to the needs of their families and homes.”

The Atlantic Ocean storm was expected to develop into a hurricane Wednesday near the Bahamas, before making landfall in Florida either later that evening or early Thursday, the National Hurricane Center said.

A hurricane warning has been issued near the Kennedy Space Center, where the rocket — NASA’s most powerful ever — is to blast off.

With Nicole gaining strength, “NASA … has decided to retarget a launch for the Artemis I mission for Wednesday, November 16, pending safe conditions for employees to return to work, as well as inspections after the storm has passed,” the agency said in a statement Tuesday evening.

NASA added that a launch occurring during a two-hour window that opens at 1:04 a.m. EST (0604 GMT) on November 16 would result in a splashdown on Friday, December 11.

A back-up launch date has been set for November 19.

NASA said it would leave the 98-meter SLS rocket on the launch pad, where it had been placed several days before.

After two launch attempts were scrubbed this summer because of technical problems, the rocket had to be returned to the Vehicle Assembly Building to protect it from Hurricane Ian.

Earlier Tuesday, Nicole was packing sustained winds near 100 kilometers per hour with higher gusts and was expected to strengthen even further, according to the NHC.

Some experts have voiced concern that the rocket, which is estimated to cost several billion dollars, could be damaged by debris from the hurricane if it remains exposed.

The SLS rocket is designed to withstand 136 kph winds at the 18-meter level, NASA said. It is designed to also withstand heavy rains at the launch pad and the spacecraft hatches have been secured to prevent water intrusion.

The uncrewed mission, dubbed Artemis 1, will bring the United States a step closer to returning astronauts to the Moon five decades after humans last walked on the lunar surface.

The goal of Artemis 1, named after the twin sister of Apollo, is to test the SLS rocket and Orion crew capsule that sits on top.

Mannequins are standing in for astronauts on the mission and will record acceleration, vibration, and radiation levels.

Dutch Group Helps Kenya’s Maasai Restore Drought-hit Lands

The Horn of Africa’s record drought has dried up wide areas of land and vegetation, left millions of livestock dead and threatened the survival of both wildlife and people. In Kenya, to reduce the impact of drought, a Dutch conservation group is helping ethnic Maasai to restore parched lands through rainwater harvesting. But with a failed rainy season forecast for the fifth time in a row, some are asking whether conservation efforts will be enough.

Uganda to End School Year Early Amid Ebola Outbreak

The Ugandan government says it will end the school year earlier than planned because of an Ebola outbreak that has affected 23 students, including eight children who died.

Millions of Ugandan students in primary and secondary schools will be affected by the decision to end the semester two weeks early, due to the ongoing Ebola virus outbreak.

Joyce Moriku Kaducu, the state minister for education, announced the closure on Tuesday.

“Pre-primary, primary and secondary schools will close for Term 3 holidays on Friday, 25th November 2022,” Kaducu said.

According to the Ministry of Education, Ebola cases were found at five schools in the Kampala, Wakiso and Mubende districts.    

Kaducu said the Cabinet of President Yoweri Museveni made the decision to close schools nationwide based on concerns that crowded schools will increase infection rates for the virus. 

The schools with affected children have been cordoned off and are being asked to decontaminate their facilities so children can safely return after the new year.

The decision to end the school term early is a disappointment to many families.  Ugandan schools were closed for two years because of the COVID-19 pandemic before reopening earlier this year.

Last Total Lunar Eclipse for Three Years Arrives Tuesday

Better catch the moon’s disappearing act Tuesday — there won’t be another like it for three years.

The total lunar eclipse will be visible throughout North America in the predawn hours — the farther west, the better — and across Asia, Australia and the rest of the Pacific after sunset. As an extra treat, Uranus will be visible just a finger’s width above the moon, resembling a bright star.

Totality will last nearly 1 1/2 hours — from 5:16 a.m. to 6:42 a.m. EST — as Earth passes directly between the moon and sun.

Known as a blood moon, it will appear a reddish orange from the light of Earth’s sunsets and sunrises. At the peak of the eclipse, the moon will be 390,653 kilometers away, according to NASA scientists. Binoculars and telescopes will enhance viewing, provided the skies are clear.

South America will get a glimpse of Tuesday’s lunar eclipse, weather permitting. Striking out altogether, Africa, the Middle East and most of Europe will have to wait until 2025.

Among those providing a livestream of Tuesday’s lunar extravaganza: Griffith Observatory in Los Angeles and the Italian-based Virtual Telescope Project.

It’s the second total lunar eclipse this year; the first was in May. The next one won’t be until 2025. Plenty of partial lunar eclipses will be available in the meantime.

War Fallout, Aid Demands Overshadow Climate Talks in Egypt

When world leaders, diplomats, campaigners and scientists descend on Sharm el-Sheikh in Egypt for talks on tackling climate change, don’t expect them to part the Red Sea or other miracles that would make huge steps in curbing global warming.

Each year there are high hopes for the two-week United Nations climate gathering and, almost inevitably, disappointment when it doesn’t deliver another landmark pact like the one agreed 2015 in Paris.

But those were different days, marked by a spirit of cooperation between the world’s two biggest polluters — the United States and China — as well as a global realization that failure to reach an agreement would put humanity on a self-chosen track to oblivion.

This November the geopolitical tiles have shifted: a devastating war in Ukraine, skyrocketing energy and food prices, and growing enmity between the West on the one hand and Russia and China on the other make for difficult conditions at a gathering that requires cooperation and consensus.

“There’s a lot of high and low expectations around this Egypt COP, a lot of mix of ambition and fatalism,” said Avinash Persaud, special envoy for the Barbados prime minister.

Here’s what to look out for during the 27th Conference of the Parties, or COP27, from Nov. 6-18 and why it might still end up being a success.

Science warnings

Scientists are more concerned about global warming than three decades ago, when governments first came together to discuss the problem because the pace of warming in the past decade is 33% faster than in the 1990s.

Greenhouse gas emissions are still rising, while tangible impacts from climate change are already being felt around the world.

But there is some progress. Before Paris, the world was heading for 4.5 degrees Celsius of warming by the end of the century compared to pre-industrial times.

Recent forecasts have that down to 2.6 C, thanks to measures taken or firm commitments governments have already made. That’s far above the 1.5 C limit countries agreed to seven years ago, however, and the time for keeping that target is fast running out.

Researchers say the world has already warmed by 1.2 C and capping temperatures at 1.5 C would require emissions to drop by 43% by the end of the decade, a highly ambitious goal. To get to the less ambitious 2 C goal emissions have to fall 27%.

“The 1.5 degrees is in intensive care and the machines are shaking. So, it is in high danger. But it is still possible,” United Nations Secretary-General Antonio Guterres said. “My objective in Egypt is to make sure that we gather enough political will to make this possibility really moving forward, to make the machines work … We’re getting close to moments where tipping points might, at a certain moment, make it irreversibly impossible to achieve. Let’s avoid it at all costs.”

Energy scramble

Prices for oil, coal and natural gas have jumped since Russia’s invasion of Ukraine. Some countries have responded by trying to tap new sources of fossil fuel.

This has raised concerns about governments backsliding on their commitments to cut emissions, including the agreement at last year’s climate talks to “phase down” the use of coal and sharply reduce the amount of methane — a powerful greenhouse gas — released into the atmosphere.

At the same time, rising fossil fuel prices have made renewable energy more competitive. Building solar and wind power plants remains more expensive for developing countries though. To help them cut their emissions quickly, rich nations are negotiating aid projects known as ‘just transition energy partnerships’, or JET-Ps, with several major emerging economies including Indonesia and India that could be finalized during or shortly after COP27.

Climate finance

One of the big sticking points in past negotiations concerned the financial support poor countries receive from rich nations to cope with climate change.

A deadline to provide $100 billion annually by 2020 was missed and now looks set to be achieved only next year. Future funding needs are likely to be in the trillions, not billions, said Mohamed Nasr, Egypt’s lead negotiator.

“The gap on finance is huge,” he said, noting that half the population of Africa doesn’t yet have access to electricity, much less clean energy.

Developed countries including the United States have also yet to make good on a pledge to double the amount they provide for adaptation, and make that half of the overall funding.

Discussions on climate finance also include the highly contentious issue of countries being compensated for the irreparable harm they’ve suffered as a result of global warming. Big polluters have strongly opposed demands for ‘loss and damage’ payments in the past, but observers say they’ve seen a softening of positions recently, including by the United States.

“I think that people are not expecting miracles in terms of a huge fund just miraculously appearing, but they are expecting a credible, meaningful pathway,” said Inger Andersen, head of the U.N. Environment Programme.

This would give countries that have done very little to cause the climate crisis but are on the front line of dealing with it “something to hold on to,” she said.

Activist voices

Swedish climate activist Greta Thunberg is not coming to this year’s gathering and recently called the U.N. process a “scam.”

Other activists have also voiced frustration at the slow pace of negotiations, given the scale of the threat posed by climate change. But Harjeet Singh of Climate Action Network International said there is no other space where all countries are equal.

“Tuvalu theoretically is as powerful as the U.S. and Malawi as powerful as the European Union,” he said of the talks. “For us as civil society it’s also a place to call out these countries, to call their bluff, to put a spotlight on those polluters and raise our voices.”

University of Maryland social scientist Dana Fisher, who studies the environmental movement, said given Egypt’s authoritarian government and an escalation of in-your-face tactics by frustrated protestors, especially youth, she would not be surprised if there are clashes.

“There’s going to be a vanguard of them who are going to be willing to break the law and engage in probably what will start out as civil disobedience, peaceful civil disobedience,” Fisher said. “And they’re probably going to get beaten up. And it’s going to be very good for mobilizing sympathizers.”

Egypt has insisted that campaigners will have “full opportunity of participation, of activism, of demonstration, of voicing that opinion.”

Eye on Africa

The gathering in Egypt will be the first time since 2016 that U.N. climate talks have taken place in Africa. Experts say it is important the continent gets more attention, given how heavily it is affected by rising temperatures.

“If we look at the 50 countries that are most vulnerable to climate change impacts and who have the least resilience, these are low income countries and most of them are in Africa,” said Preety Bhandari of the World Resources Institute. “So it is fortuitous that we are having this particular COP in Africa to highlight what the vulnerable countries are asking from the climate regime.”

Campaigners say that recognizing the challenges Africa faces and prioritizing the needs of vulnerable countries is essential for a successful outcome this year.

WHO: Rise in Ebola Outbreaks in Africa Linked to Climate Change

World health officials are linking a significant rise in African Ebola outbreaks in this century to climate change.    

Uganda’s September 20 Ebola outbreak is just the latest in a growing number of eruptions of this deadly hemorrhagic disease in Africa. Since 2000, the World Health Organization has reported 32 outbreaks of Ebola, 19 in the last decade compared to 13 in the preceding one.

Ebola is one of a range of zoonotic diseases — infections originating in animals and jumping to humans. A WHO analysis finds Ebola and other viral hemorrhagic fevers constitute nearly 70% of these outbreaks. The remaining 30% include dengue fever, anthrax, plague, and monkeypox.  

WHO Africa incident manager for the Ebola outbreak in Uganda, Patrick Otim, says the number of zoonotic diseases occurring in the region in the last decade has increased by more than 63%.

“There have been a couple of researchers that have shown a possible link between the climatic changes that we are seeing and the increase in zoonotic diseases, and for this particular case for Ebola, for instance,” he said.

Otim said diseases are caused by several factors. Ebola, he said, is strongly influenced by the human factor. As populations increase and people encroach on wildlife habitats, interaction with animals increases. This, he said, increases the spread of disease to humans.

Otim said temperature and climatic changes also spur migration and movement of some Ebola virus hosts. 

“For the Ebola virus, we know that the bats and other animals are hosts of this particular virus,” he said. So, when they move from areas where, for instance, there is drought or whether areas that are no longer conducive for them and they move to favorable areas, they may move into an area where the human population is inhabiting and therefore the interaction between the humans increases.”

WHO says Ebola now has spread to seven districts in Uganda beyond the original epicenter in the Mubende district. The latest reports put the number of cases at 131, including 48 deaths.

The current Ebola outbreak in Uganda has been triggered by the so-called Sudan strain for which there is no vaccine. WHO said several promising candidate vaccines soon will undergo clinical trials to evaluate their potential against Ebola.

Over 120 Leaders to Attend Climate Talks; Egypt Says Positive on Protest

More than 120 world leaders will attend this year’s U.N. climate talks, and requests by environmental activists to stage a rally during the event would be responded to “positively,” host Egypt said.

Veteran diplomat Wael Aboulmagd, who heads the Egyptian delegation, told reporters Friday that his country had been working for months to set the scene for “meaningful outcomes” at the two-week meeting in the Red Sea coastal resort of Sharm el-Sheikh starting Sunday.

“We have, I think about 121 maybe, and the number is growing, heads of state and government here,” he said during an online briefing. “We hope that it will be a watershed moment.” Leaders such as U.S. President Joe Biden and British Prime Minister Rishi Sunak confirmed their attendance, but Aboulmagd said other major heads of state such as China’s Xi Jinping and India’s Narendra Modi would not be going.

Aboulmagd said recent scientific reports highlighted the urgency of tackling global warming.

“Everyone is now aware of the gravity of the situation, of the enormity of the challenge, and have come here hopefully to work together,” he said.

Greenhouse gases, financial aid

Several thorny issues will be discussed at the November 6-18 talks, including further cutting greenhouse gas emissions and boosting financial aid for poor countries struggling with the impacts of climate change. It is the first such meeting held in Africa since 2016. Over 40,000 people have registered for the event.

Aboulmagd appealed to negotiators to engage constructively. “We cannot afford to waste any time,” he said. “So everyone must rise to the occasion and must move away from the adversarial winner-takes-all approach that has plagued this process for too long.”

Civil society groups have expressed concern that their presence at this year’s talks will be restricted, citing Egypt’s questionable human rights record.

But Aboulmagd said activists would get their space, with special arrangements already put in place “for those who want to organize demonstrations or protests or stand-ins.”

Asked about the possibility of holding a large rally midway through the talks, as has traditionally happened in previous meetings, he said, “That will be taken care of.”

Organizers would need to submit the names of contact persons, and city officials must approve the planned route.

“Once a request to that effect comes, it will be responded to positively,” he said.

Egypt would press diplomats to live up to the lofty pledges their leaders had made, Aboulmagd said, warning that so far, these had not been translated into the negotiating rooms.

“This separation between the reality in the public sphere and what actually happens in negotiating rooms cannot continue,” he said. “It is about real lives that are being lost and future lives that will be devastated” by unchecked climate change.

Astronomers Spot Closest Known Black Hole to Earth

Astronomers have discovered the closest known black hole to Earth, just 1,600 light-years away.

Scientists reported Friday that this black hole is 10 times more massive than our sun. And it’s three times closer than the previous record-holder.

It was identified by observing the motion of its companion star, which orbits the black hole at about the same distance as Earth orbits the sun.

The black hole was initially identified using the European Space Agency’s Gaia spacecraft, said Kareem El-Badry of the Harvard-Smithsonian Center for Astrophysics.

El-Badry and his team followed up with the International Gemini Observatory in Hawaii to confirm their findings, which were published in Monthly Notices of the Royal Astronomical Society.

The researchers are uncertain how the system formed in the Milky Way. Named Gaia BH1, it’s located in the constellation Ophiuchus, the serpent-bearer.

Death in CRISPR Gene Therapy Study Sparks Search for Answers

The lone volunteer in a study involving a gene-editing technique has died, and those behind the trial are now trying to figure out what killed him.

Terry Horgan, a 27-year-old who had Duchenne muscular dystrophy, died last month, according to Cure Rare Disease, a Connecticut-based nonprofit founded by his brother, Rich, to try and save him from the fatal condition.

Although little is known about how he died, his death occurred during one of the first studies to test a gene editing treatment built for one person. It’s raising questions about the overall prospect of such therapies, which have buoyed hopes among many families facing rare and devastating diseases.

“This whole notion that we can do designer genetic therapies is, I would say, uncertain,” said Arthur Caplan, a medical ethicist at New York University who is not involved in the study. “We are out on the far edge of experimentation.”

The early-stage safety study was sponsored by the nonprofit, led by Dr. Brenda Wong at the University of Massachusetts Chan Medical School and approved by the Food and Drug Administration. The hope was to use a gene-editing tool called CRISPR to treat Horgan’s form of Duchenne muscular dystrophy. The rare, genetic muscle-wasting disease is caused by a mutation in the gene needed to produce a protein called dystrophin. Most people with Duchenne die from lung or heart issues caused by it.

At this point, it’s unclear whether Horgan received the treatment and whether CRISPR, other aspects of the study or the disease itself contributed to his death. Deaths are not unheard of in clinical trials, which test experimental treatments and sometimes involve very sick people.

But trials involving CRISPR are relatively new. And Fyodor Urnov, a CRISPR expert at the Innovative Genomics Institute at University of California, Berkeley, said any death during a gene therapy trial is an opportunity for the field to have a reckoning.

“Step one is to grieve for the passing of a brave human soul who agreed to be basically a participant in an experiment on a human being,” Urnov said. “But then, to the extent that we can, we must learn as much as we can to carve out a path forward.”

Few answers yet

A statement from Cure Rare Disease said multiple teams across the country are looking into the details of the trial and its outcome, and the company intends to share findings with the scientific community.

“It will probably be 3-4 months to come up with a full conclusion,” said spokesman Scott Bauman. “At this stage of the game, saying anything is pure speculation.”

The company, which is also working on 18 other therapeutics, said in its statement that the team’s work is essential not only to shed light on the study’s outcome but also “on the challenges of gene therapy broadly.” Meanwhile, it said, “we will continue to work with our researchers, collaborators, and partners to develop therapies for the neuromuscular diseases in our pipeline.”

Bauman said the company has filed a report on death the with the FDA as required. The FDA declined to release or confirm the report.

Sarah Willey, spokesperson for Chan Medical School, said scientists there provided data to the company for the report. She later emailed to say no one there would comment further; out of respect for the family’s wishes, all information would come from Cure Rare Disease.

A crucial question is whether CRISPR played a part in Horgan’s death.

The chemical tool can be used to “edit” genes by making cuts or substitutions in DNA. The tool has transformed genetic research and sparked the development of dozens of experimental therapies. The inventors of the tool won a Nobel Prize in 2020.

In this case, scientists used a modified form of CRISPR to increase the activity of a gene. The CRISPR therapeutic is inserted directly into the body and delivered to cells with a virus.

But CRISPR is not perfect.

“We know that CRISPR can miss its target. We know that CRISPR can be partially effective. And we also know that there may be issues with … viral vectors” that deliver the therapy into the body, Caplan said. “Red flags are flying here.”

Another difference? The recent trial involved just one person — a type of trial Caplan is skeptical about.

A ‘medical pioneer’

On the company’s website, Horgan was described as a “medical pioneer” who “will be remembered as a hero.”

In 2020, the Montour Falls, New York resident blogged that he was diagnosed with Duchenne at age 3. As a kid, he said, he loved computers — once building his own — and would play catch in the driveway with his family when he could still walk. Later in his life, he used a motorized wheelchair. He studied information science at Cornell University and went on to work at the school in the information science department.

“As I grew up and began to understand what it meant to have DMD, my fears about this disease began to grow as it began to manifest,” Horgan wrote. “There weren’t many, or any, trials available to me through the years” — until this one brought the prospect of a customized drug.

The plan was to suppress Horgan’s immune system to prep his body for a one-time, gene-editing therapy delivered by IV at UMass medical school, followed by monitoring in the hospital. The therapy is designed to increase the level of an alternate form of the dystrophin protein using CRISPR, with the goal of stabilizing or potentially reversing the progression of symptoms.

Urnov, scientific director for technology and translation at the Berkeley genomics institute, said no other trial targeted this disease using this kind of virus to deliver this particular payload with its modified form of CRISPR.

US Flu Season Off to Fast Start as Other Viruses Spread

The U.S. flu season is off to an unusually fast start, adding to an autumn mix of viruses that have been filling hospitals and doctors’ waiting rooms.

Reports of flu are already high in 17 states, and the hospitalization rate hasn’t been this high this early since the 2009 swine flu pandemic, according to the Centers for Disease Control and Prevention. So far, there have been an estimated 730 flu deaths, including at least two children.

The winter flu season usually ramps up in December or January.

“We are seeing more cases than we would expect at this time,” the CDC’s Dr. José Romero said Friday.

A busy flu season is not unexpected. The nation saw two mild seasons during the COVID-19 pandemic, and experts have worried that flu might come back strong as a COVID-weary public has moved away from masks and other measures that tamp the spread of respiratory viruses.

Community Montessori school in New Albany, Indiana, switched to virtual teaching at the end of the week because so many students were out sick with the flu. Beginning Monday, the school’s 500 students will go back to wearing masks.

“Everybody just wants kids on campus, that is for sure,” said the school’s director, Burke Fondren. “We will do what we need to do.”

There may be some good news: COVID-19 cases have been trending downward and leveled off in the past three weeks, Romero said.

And in a few parts of the country, health officials think they may be seeing early signs that a wave of another respiratory virus may be starting to wane. RSV, or respiratory syncytial virus, is a common cause in kids of cold-like symptoms such as runny nose, cough and fever. While RSV continues to rise nationally, preliminary data suggest a decline in the Southeast, Southwest and in an area that includes Rocky Mountain states and the Dakotas, CDC officials said.

Experts think infections from RSV increased recently because children are more vulnerable now, no longer sheltered from common bugs as they were during pandemic lockdowns. Also, the virus, which usually affects children ages 1 and 2, is now sickening more kids up to age 5.

At the University of Chicago Medicine Comer Children’s Hospital, beds have been full for 54 days straight.

“The curves are all going up for RSV and influenza,” said Dr. John Cunningham, Comer’s physician-in-chief.

RSV illnesses seem to be unusually severe, he added.

Comer has had to turn down transfer requests from other hospitals because there was no room. Chicago-area hospitals had been able to transfer kids to Missouri, Iowa and Wisconsin, but that’s stopped.

“They have no more beds, either,” Cunningham said.

There’s not yet a vaccine against RSV, but there are shots for flu and COVID-19. Health officials say flu vaccinations are down in both kids and adults compared with before the pandemic, although they are up in children from last year.

So far this season, there have been an estimated 1.6 million flu illnesses and 13,000 hospitalizations. Flu activity is most intense in some of the areas where RSV is fading, including the Southeast, according to CDC data.

Pfizer Study: COVID Booster Significantly Ups Protection Against Variants

U.S. pharmaceutical company Pfizer and its German partner BioNTech said Friday a new study indicates their COVID-19 booster vaccination provides significant antibody protection against the omicron variant and its subvariants among adults.

The companies introduced a new booster targeting the omicron variant in September, and U.S. Food and Drug Administration (FDA) approved it for use last month, along with a similar vaccine produced by U.S. drug company Moderna, as have several other countries.

In their statement, the companies said the new data show the COVID-19 booster, adapted to target the omicron BA.4 and BA.5 subvariants, generated four times the neutralizing antibodies against the omicron variants among adults ages 55 and older than their original vaccine.

The study also showed after one month, the booster dose generated more than 13 times the number of neutralizing antibodies against the variants in patients older than 55 than patients who received the original vaccine; 9.5 times the antibodies in patients 18 to 55 years old.

Pfizer Chairman and Chief Executive Officer Albert Bourla said in the statement that as the United States heads into the holiday season, the new data should encourage people who have not done so to seek out a booster shot as soon as they are eligible to receive it — six months after their last vaccination.

Pfizer and BioNTech said they have shared the data with the FDA and plan to share it with the European Medicines Agency and other global health authorities as soon as possible.

A booster dose of the omicron-targeting vaccine has been authorized by the FDA for emergency use for ages 5 years and older and has also been granted marketing authorization in the EU by the European Commission.

Some information for this report came from The Associated Press and Reuters.

Australia Warns of New COVID Surge

Australia can expect another wave of COVID-19 infections in coming weeks, according to experts, as new variants circulate. Coronavirus cases are rising quickly in New South Wales and Victoria, Australia’s most populous states.

The World Health Organization declared COVID-19 a global pandemic on March 11, 2020. The declaration is still active.

In Australia, life is resembling what it was before the virus. Most disease-control measures, such as mandatory mask-wearing on public transport and self-isolation for people testing positive to COVID-19, have been scrapped. Some restrictions, however, still apply to health, disability and aged-care facilities.

Public health authorities in the states of New South Wales and Victoria have warned that another surge in infections is approaching. Official data has shown that in the last week of October, coronavirus case numbers increased in all Australian states and territories except Queensland.

There were 9,707 positive diagnoses in the week ending Oct. 29 in New South Wales, an 11% increase from the previous week.

Government data has shown that more than 95% of Australians over 16 have had at least two doses of a COVID-19 vaccine.

In a video posted on Twitter on Thursday, New South Wales Chief Health Officer Kerry Chant warned of a spike in infections.

“By looking at all the local information we have and what is happening overseas we believe COVID cases will rise in the coming weeks,” Chant said. “The protection the New South Wales community has from vaccination and previous infection continues to reduce the risk of severe illness. However, the elderly and those with underlying health conditions will continue to be at higher risk.”

COVID-19 continues to spread in other countries.

China’s COVID-19 cases hit their highest in 2½ months Thursday, according to health authorities. The world’s most populous nation is following President Xi Jinping’s zero-COVID policy, which has seen millions of people locked down in major cities. The WHO has said China has had more than 9 million confirmed coronavirus cases since the pandemic began.

In the United States, White House chief medical adviser Dr. Anthony Fauci said Thursday that new omicron variants were gaining ground across the country as winter approaches.

Researchers at University College London say Britain could be relatively free of COVID-19 this Christmas but potentially faces another wave of cases in January.

The European Centre for Disease Prevention and Control has said COVID-19 variants BQ.1 and BQ.1.1 are likely to drive up cases in the months ahead in Europe.

As of Thursday, there have been more 628 million confirmed COVID-19 cases globally, including about 6.5 million deaths reported to the WHO.

Isolation has helped to protect some communities from the virus. The WHO said that Niue, a small island in the South Pacific Ocean with a population of 2,000, has recorded 85 COVID-19 cases and no fatalities during the pandemic.

Report: Tanzania’s Elephant Population Recovering 

Tanzania’s Ministry of Tourism released a census this week showing the country’s elephant population has stabilized.

Tanzania’s elephants were among the hardest hit by poaching in Africa, with numbers dropping 60 percent between 2009 and 2014. But authorities say joint efforts with conservation groups and local communities have drastically reduced poaching and helped to attract tourist dollars.

Just under 20,000 elephants were recorded in a survey that covered about 90,000 square kilometers of the Katavi-Rukwa and Ruaha-Rungwa landscapes in western Tanzania, including parks, game reserves and other protected areas.

The government said the results confirm that the landscape remains the most important in East Africa in terms of elephant numbers and contains the largest population on the continent outside Zimbabwe and Botswana.

Ernest Mjingo, a managing director of the Tanzania Wildlife Research Institute, a department of the Ministry of Tourism, said the world would now see Tanzania as very serious about conservation and doing well at it. And if the world does see that, he said, it would be a credit to the government and would also increase revenue, because Tanzania will become a prime destination for tourists because of the animal population. He added that it could also become a U.N. World Heritage Site, since it would have species that would not be available in other places.

The report said poaching had dramatically decreased over the last few years.

In the last report, conducted in 2018, the ratio of elephant carcasses to live animals was 14 percent. Now, it’s just 1.4 percent, thanks to government and stakeholders’ efforts in strengthening wildlife protection.

Tourism experts such as Makubi Mabula see the results of the census as a good sign for Tanzania’s economic prospects.

“Honestly, the results show a green light toward the future of tourism in our country,” he said through a translator. ” … Many tourists come to see animals like elephants, lions, rhinos and others. So, with the elephant population stabilizing, the national income will increase. It really gives us the peace we tourist stakeholders need to believe that the tourism industry will grow fast.”

Along with elephants, the survey also confirmed that the populations of 25 other key mammal species in Tanzania have stabilized, including buffaloes, zebras, hartebeests, impalas and giraffes.

Explainer: Why the Black Sea Grain Deal Is Vital for Global Food Security

A landmark deal to allow grain exports from Ukraine, which was back on track Wednesday after being briefly suspended, has played a crucial role in easing a global food crisis sparked by the Russian invasion of Ukraine.

Brokered by the United Nations and Turkey and signed by Moscow and Kyiv on July 22, the agreement established a protected sea corridor to allow grain shipments to resume for the first time since the fighting began in February

Here is what we know about the deal, known as the Black Sea Grain Initiative:

Why was it needed?

When Russian troops attacked in late February, Moscow imposed a blockade on Ukraine’s Black Sea ports, halting all agricultural exports from one of the world’s breadbaskets.

The move left 20 million metric tons of grain stranded in Ukraine’s ports, causing food prices to surge worldwide.

Before the war, up to 90% of Ukraine’s wheat, corn and sunflower exports were transported by sea, mostly from Odesa, with many developing countries relying heavily on Kyiv for grain.

Agricultural commodity prices were high before the war because of the post-COVID-19 economic recovery, but the conflict pushed the price of grains such as wheat and corn to levels unsustainable for countries dependent on their import, such as Egypt, Lebanon and Tunisia.

What does the deal cover?

The deal ensures the safe export of grain, foodstuffs and fertilizers, including ammonia, from three Black Sea ports in southwestern Ukraine: Odesa, Chornomorsk and Pivdennyi.

The first grain ship to leave under the U.N.-backed deal set sail on August 1.

According to U.N. figures as of November 1, a total of 9.7 million metric tons of grain and other agricultural products have been transported in the first three months of the initiative, the vast majority involving wheat and corn.

Valid for 120 days, the agreement is up for renewal on November 19 in a process that can be done automatically without further negotiations.

The U.N. says extending the deal is crucial for global food security and is pushing for it to be renewed for one year.

Although the initiative is working well, shipments are about 40-50% lower than what they were before Russia’s invasion, the U.N. says.

How does it work?

According to the U.N.’s website, the agreement establishes a safe corridor between the three Ukrainian ports and an area in Turkish waters where the vessels are inspected before being allowed to continue their journey.

To monitor the agreement, a joint command and control center was set up in Istanbul to oversee smooth operations and resolve disputes.

Known as the Joint Coordination Center (JCC), the JCC has four teams of eight inspectors — two each from Russia, Ukraine, Turkey and the U.N.

These teams inspect outbound vessels carrying grain at the Turkish inspection area to ensure all merchandise is approved.

The teams also examine empty ships returning to Ukraine to ensure they are not carrying any weapons or other unauthorized goods or people.

Safe passage

The deal establishes a buffer zone of 10 nautical miles around each vessel traveling along the corridor with no military ships, equipment or drones allowed within that radius.

All ship movements logged by the JCC are transmitted to the relevant military authorities to prevent any incidents, with any violations or threats to be handled by the JCC.

At the start of the war, Ukraine mined its main Black Sea ports to head off threats of a Russian attack from the sea, but experts said it would take too long to de-mine all these areas.

The deal allows Ukrainians to guide the ships along safe routes that avoid known mine fields and into and out of its territorial waters.

Deal briefly suspended

On October 29, Russia said it was suspending its participation in the deal, accusing Ukraine of using the shipping corridor to launch a drone attack on its Black Sea fleet in Crimea’s Sevastopol port.

After a call between the Russian and Turkish defense ministers, the deal resumed operation at 0900 GMT on November 2 with Moscow saying it had received written guarantees from Kyiv ensuring the corridor would not be used for attacking Russian forces.
