The battle to stem climate change may be lost as new information indicates the Amazon rain forest is turning from a carbon sink – or area that absorbs CO2 – into a source of carbon dioxide, the World Meteorological Organization warns. 

The latest edition of the WMO’s Greenhouse Gas Bulletin reports emissions of carbon dioxide, methane, and nitrous oxide once again broke all records last year.

The U.N. agency’s report warns the concentrations of these greenhouse gas emissions into the atmosphere are driving climate change. It says carbon dioxide, the single most important greenhouse gas, accounts for approximately 66 percent of the warming effect on the climate.

The secretary-general of the World Meteorological Organization, Petteri Taalas, says about half of CO2 emissions remains in the atmosphere for centuries. He says the other half is taken up by oceans and land ecosystems.

He says it is not clear for how much longer forested areas, often referred to as the lungs of the Earth, will continue to act as effective carbon sinks. 

“We have already seen some alarming indications that, for example, Amazonian rain forest ecosystem, which used to be a major sink of carbon, has become now a source of carbon, which is alarming,” Taalas said. “And this is related to deforestation in the area and also changes in local climate because of this deforestation.”

Oksana Tarasova, who heads the WMO’s Atmospheric and Environment Research Division, says the WMO only now is revealing this new finding because it has taken nine years of observation to gather the measurement data set needed to understand the changes taking place. She says not all of the Amazon forest is turning from a carbon sink to a net producer of carbon. 

“So, the Western part of the Amazonia still continues to work as a carbon sink at this point. But we do not know for how long that will continue this way,” Tarasova said. “We are making the measurements there and keeping our track on what is happening there. … I would take the whole Amazonia as a whole that is seen that it is a sink, but its capacity is substantially reduced.”

Meteorologists say climate change negotiators at an upcoming conference in Scotland must take concrete action and make concrete pledges to reduce carbon dioxide emissions.

They say setting carbon neutral targets will not work in stemming climate change. They also warn the world is heading toward a temperature rise of 2.5 degrees Celsius by the end of this century. This, they say, is far more than the Paris Agreement target of 1.5 to two degrees Celsius above pre-industrial levels.

Health care activists in Cameroon are visiting homes, markets and farms this month, encouraging women to get free screenings for breast cancer. The central African state says the number of women diagnosed with breast cancer has risen sharply over the past year because many women delayed screenings for fear of COVID-19 infections. The push to increase screenings is part of this year’s breast cancer awareness month in October.

Civilians, mostly women, visit various neighborhoods in Yaoundé asking people to go to hospitals for free breast cancer screening.

Each group of a dozen people includes medical staff members, representatives of healthy living organizations, cancer patients and their family members.

Among those participating is 24-year-old Amin Ruth Tabi of the Noela Lyonga Foundation, a Cameroon-based NGO. The foundation’s main objective is giving hope to persons who have lost hope either due to frustration, stress or ill health.

Tabi says she wants to stop people from dying from breast cancer.

“Every female seven to ten days after menstruation is supposed to conduct a breast self-examination to look for abnormal nodules, redness, fluid coming from the nipples, orange skin appearance on the breast because breast cancer is treated well and quickly when it is noticed at an early stage,” she said.

Cameron’s Health Ministry said several thousand women came out in at least 11 towns including the capital Yaoundé, the commercial capital Douala and the English-speaking western towns of Kumba, Buea, Limbe, and Bamenda Kumbo.

Claudette Mani, 36, says she was diagnosed with breast cancer in December 2020. She says thanks to prompt medical intervention and assistance from NGOs, her life was saved.

“I was so isolated, I was so weak, looked very bad and I felt like it was the end of the world,” she said. “At first just from my looks you will know that I have a problem, but now I am healthy, strong, and looking good. They [humanitarian groups] brought in doctors, educated us on how to feed ourselves, how to do exercises, to stay strong, eliminate the fact from our heads that we have this breast cancer and be focused on our dreams.”

Cameroon’s Association of Cancer Patients says breast cancer patients suffer from prejudices. Family members often think breast cancer is some sort of divine punishment for wrongdoing. The association says because of either illiteracy or lack of financial means, families abandon members diagnosed with breast cancer.

Cameroon’s Health Ministry says screening programs with mammography can lead to earlier diagnosis, and that coupled with effective treatment, will lead to reductions in breast cancer mortality.

Cameroon reports that in 2019, 3,000 of the 5,000 patients diagnosed with breast cancer died. In 2020, the number of breast cancers diagnosed rose to over 7,000 with close to 5,000 deaths.

Professor Paul Ndom is president of Cameroon’s National Committee for Cancer Prevention.

Ndom says many people neglect going to hospitals for consultation because breast cancer is not painful at its early stages. He says people at high risk of developing breast cancer are women who smoke cigarettes and drink alcohol, women who are not physically active and women who refuse to visit hospitals for fear they will be exposed to COVID-19 infections.

Ndom said the government of Cameroon subsidizes treatment for people diagnosed with breast cancer.

The October Breast Cancer Awareness month campaign was launched by the American Cancer Society and Imperial Chemical Industries to encourage women to get regular screening for breast cancer. The month-long activities educate women to reduce their breast cancer risks, be screened and seek medical attention if a suspicious lump is detected.

The director-general of the World Health Organization said Sunday that unless countries use existing tools in the fight against the pandemic effectively, there will be no end in sight. “The pandemic will end when the world chooses to end it,” Tedros said addressing World Health Summit, a global forum held in Germany.

“We have all the tools we need — effective public health tools and effective medical tools. But the world has not used those tools well,” Tedros said, addressing participants drawn from 100 countries online.

The barriers to fulfilling WHO’s goal of vaccinating 40% of every country’s population against the coronavirus are “politics and profit,” the WHO chief said, “not production.”

“The countries that have already reached the 40% target, including all G-20 countries, must give their place in the vaccine delivery queue to COVAX and the African Vaccines Acquisition Trust,” Tedros said. COVAX is the international collaboration established for the equitable distribution of the COVID vaccine.

The WHO official also urged vaccine producers to “prioritize and fulfil their contracts with COVAX and AVAT [the African Vaccine Acquisition Trust]” and become “far more transparent about what is going where.” AVAT is an African Union initiative focusing on providing access to COVID-19 vaccines across Africa. 

He urged vaccine manufacturers to “share know-how, technology and licenses, and waive intellectual property rights.”

“We’re not asking for charity,” Tedros said,” we’re calling for a common-sense investment in the global recovery.” 

A report in The Washington Post says Americans living abroad are struggling to receive COVID vaccines, while many of their U.S. counterparts are starting to receive booster shots after receiving their first two vaccine doses. 

Marylouise Serrato, executive director of American Citizens Abroad, told the Post, “You have Americans who are filing and paying taxes, and a promise by the administration that all Americans will get vaccinated, and yet that whole community has been left out of the equation.” 

The White House “has insisted that it has no special responsibility to vaccinate Americans abroad,” the Post reported. At least 9 million Americans are living overseas, the report added.

A surge of British COVID cases has Dr. Edward Morris, the president of the Royal College of Obstetricians and Gynecologists, concerned the National Health Service may not be able to provide “the care it needs to” for women giving birth, according to a report in The Guardian.

Morris also said the COVID surge has also resulted in the creation of an enormous backlog of cases of women who have had to postpone gynecological treatments.

The Johns Hopkins University Coronavirus Resource Center reported early Monday that it has recorded 243.7 million global COVID infections and nearly 5 million global deaths. Almost 7 billion vaccines have been administered, according to the university’s data.

“Coral reefs are amazing and beautiful, and we must conserve them,” Sam Purkis, chair of the department of marine geosciences at the University of Miami, told VOA.

Although coral reefs only cover 0.1% of the ocean floor, they are a lifeline for the planet.  With the most biodiverse marine ecosystem on earth, they contain 25% of all marine life, including more than 4,000 fish species.

Besides food, “corals provide economic, ecological and even cultural value,” where local communities living near the reefs bond over fishing activities, explained Robert Richmond, director of the Kewalo Marine Laboratory at the University of Hawaii.

“Corals also hold potential drugs from the sea, the vast majority of which we haven’t discovered yet,” Nancy Knowlton, scientist emeritus at the Smithsonian’s National Museum of Natural History, said during an interview with VOA.

However, coral experts have sounded the alarm that the reefs could disappear, threatened by a number of factors, including pollution, overfishing and especially climate change.

The latest study on the status of coral reefs, released earlier this month by the International Union for Conservation of Nature, blamed climate change for killing 14% of coral reefs in just one decade.

“Large-scale bleaching events caused by elevated sea surface temperatures are the greatest disturbance to the world’s coral reefs,” the report said.

Despite the gloomy picture, coral reef experts say there is hope, despite significant coral losses worldwide.

“We still have corals that are healthy, but it requires a massive global effort to protect them,” said Elizabeth Mcleod, leader of The Nature Conservancy’s global reef work in Arlington, Virginia.

Richmond is also optimistic.

“Although coral reefs are severely threatened, they are not doomed,” he said. If we take “aggressive action against climate change, then we will have coral reefs as a legacy for the future.”

“We’re not going to be able to restore them back to pristine condition like they were 50 years ago,” added Jennifer Koss, director of the coral reef conservation program at the National Oceanic and Atmospheric Administration.  “But through restoration, and by curtailing climate change, coral ecosystems have a chance to flourish again.”

The experts agree that curbing carbon dioxide emissions that cause global warming is key.

“We need to significantly lower our emissions, so there is actually hope for coral reefs,” Madhavi Colton, executive director of the Coral Reef Alliance, in Oakland, California, told VOA.

The most striking impact of warmer ocean temperatures is bleaching, when corals turn eerily white.

“We’re seeing this drastic decline in coral cover,” said Purkis. “Unless conditions improve, many corals will die from bleaching because the organisms are weakened and usually catch a disease.”

Eliminating other stressors may help the reefs better withstand bleaching.  

“If we combat stressors like overfishing and improve water quality, the reefs can better tolerate global changes and are more likely to survive and reproduce,” Colton said.

Discovering heat resistant corals may also be a game-changer.

“In the Red Sea, you find corals that have adapted and are resilient and responsive to the heat.  So, these ‘super reefs’ have solved the problem, and we should figure out how they’ve done that and use them for restoration efforts,” said Stephen Palumbi, a marine biology professor at Stanford University’s Hopkins Marine Station.

Local involvement can make a difference in protecting coral reefs.

In America Samoa, the local population is working on watershed projects that help preserve coral reefs, Koss said.  Rain gardens were installed on land to hold back sediment that can smother the corals.

Various methods are being used in Indonesia to safeguard the reefs.

“The locals are watching for illegal fishing, and some communities are partnering with ecotourism groups to raise awareness about the importance of the reefs,” Mcleod said.

A reef restoration program has been particularly successful in the Pacific island nation of Palau.

Citizen scientists are using readily available materials like rebar and cable ties to make frames for heat-resistant coral nurseries, Palumbi said.

“We’ve been teaching community college students through peer mentoring and on Zoom how to do these experiments and get the results on Instagram. The young people are taking steps to secure their own future.”

British finance minister Rishi Sunak’s budget this week will include an extra $8.1 billion of spending for the health service over the next few years to drive down waiting lists, the finance ministry said on Sunday.   

The sum comes on top of an $11 billion package announced in September to tackle backlogs built up over the COVID-19 pandemic, the finance ministry said.   

The spending is aimed at increasing what is termed elective activity in the National Health Service (NHS) — such as scans and non-emergency procedures — by 30% by the 2024/25 financial year. 

The increase comprises $3.2 billion for testing services, $2.9 billion to improve the technology behind the health service, and $2 billion to increase bed capacity.   

“This is a game-changing investment in the NHS to make sure we have the right buildings, equipment and systems to get patients the help they need and make sure the NHS is fit for the future,” Sunak said in a statement. 

Sunak is expected to set fairly tight limits for most areas of day-to-day public spending in his budget on Wednesday, which will seek to lower public debt after a record surge in borrowing during the pandemic.

Pakistan and Afghanistan, the only two countries where polio still paralyzes children, marked World Polio Day (October 24) Sunday amid excitement and hopes that global eradication of the crippling disease is within reach. 

The neighboring countries constitute a bloc where the disease has been endemic; but each has detected just one case of wild polio so far this year compared to 53 in Afghanistan and 81 in Pakistan in October 2020. The number of cases so far in 2021 is the lowest in history, according to World Health Organization officials.

A polio vaccination campaign in Pakistan has faced challenges in particular over the past two years — due to vaccine hesitancy and the COVID-19 pandemic, which led to a five-month pause in polio immunization campaigns starting in March of 2020.

“We have reason to be optimistic,” said Aziz Memon of Rotary International, which coordinates a global polio eradication program.

Memon told VOA the declining trend of reported polio cases and negative environmental samples suggest “a positive outlook” for polio eradication in Pakistan and Afghanistan, stressing the need for capitalizing on what he described as an “unprecedented” opportunity to stop wild polio transmission. 

“We are currently in the high season for polio transmission in Afghanistan and Pakistan, so it’s never been more important to ensure that polio immunization and surveillance remain a top priority, particularly as the pandemic continues to threaten immunization programs around the world,” he said. 

Memon said restrictions on public movement to prevent COVID-19 from spreading was one of the key contributing factors leading to the recent decline in polio cases in Pakistan. 

“Inter-city and intra-city public transportation remained suspended across the country during the pandemic lockdowns, which restricted many nomadic families from traveling to other cities in search of job opportunities,” he said.

Memon said the resumption of mass polio vaccination campaigns and the natural immunity induced by the wild polio outbreaks of previous years have also contributed to the current reduction in cases. 

The Pakistani government reported earlier this month that its third vaccination campaign of the year in mid-September succeeded in the administering of polio drops to more than 40 million children across the country. 

Afghan house-to-house drive 

The United Nations last week announced that a house-to-house polio vaccination drive for all children under 5 in Afghanistan will restart on November 8 for the first time in more than three years, now that the conflict-torn country’s new Taliban government has granted approval. 

“Given that Pakistan and Afghanistan are a single epidemiological bloc, this represents a great opportunity for both countries to reach even more children with lifesaving polio vaccines,” said Memon, while welcoming the Taliban’s decision to lift the ban on house-to-house polio vaccination. 

Rotary’s Global Polio Eradication Initiative was founded in 1988. The program has since reduced infections by more than 99.9 percent worldwide and immunized nearly 3 billion children against polio, preventing more than 19.4 million cases of paralysis. But Rotary officials predict “hundreds of thousands of children could be paralyzed” if polio is not eradicated within 10 years. 

International eradicators warn outbreaks of circulating vaccine-derived polioviruses (cVDPVs) also pose a major barrier to achieving a polio-free world, calling for increased vigilance in swiftly addressing it.

The outbreak occurs if not enough children in any given community are vaccinated and the weakened live poliovirus contained in the oral polio vaccine starts to circulate, mutating to a form that can cause paralysis. 

“Multiple countries, including Pakistan and Afghanistan, are facing outbreaks of cVDPV type 2, and to address them, a new polio vaccine that carries less risk of changing to a harmful form that could cause paralysis in low-immunity settings has been developed,” Memon said.

A Financial Times report says COVAX, the global collaboration established to ensure that poor countries have access to the COVID-19 vaccine, has “largely failed.” 

“Wealthy countries have received over 16 times more COVID-19 vaccines per person than poorer nations that rely on the COVAX program backed by the World Health Organization,” the newspaper reported.

Millions of people in the world’s poorest countries have not yet received their first shots of the vaccine, while people in the wealthiest countries have access to booster shots, following their initial inoculations.

The disparity, The Financial Times warned, “could lead to a rise in cases and the emergence of more virulent strains, and hold back the global economic recovery.” 

The World Health Organization’s director-general said Friday 82 countries are at risk of not meeting WHO’s goal of having 40% of every country’s population vaccinated against COVID by the end of the year. Tedros Adhanom Ghebreyesus said, “For most of those countries, it’s simply a problem of insufficient and unpredictable supply.” 

Earlier this month, Britain reported its highest daily number of COVID-19 related deaths since March 9. A government advisor told a BBC television show Saturday that people should not wait for government mandates to begin initiating measures to prevent the transmission of the coronavirus.

Peter Openshaw, a member of the New and Emerging Respiratory Virus Threats Advisory Group, told BBC Breakfast, “I think hospitals in many parts of the country are barely coping actually” under the weight of COVID cases.

“The sooner we all act,” Openshaw said, “the sooner we can get this transmission rate down and the greater the prospect of having a Christmas with our families.”

British Prime Minister Boris continues to dismiss calls for renewed COVID-19 restrictions, saying there is nothing to indicate those moves will be necessary in the coming months, despite the fact Britain is experiencing a dramatic surge in COVID-19 infections. 

Russia is preparing for or a weeklong workplace shutdown and the reimposition of a partial lockdown because of a surge in COVID-19 infections and deaths.

Daily coronavirus deaths in Russia have been rising for weeks because of sluggish vaccination rates, casual attitudes toward precautionary measures and the government’s hesitance toward tightening restrictions. The country’s national task force on COVID-19 said only about one-third of Russia’s 146 million people have been vaccinated, straining the country’s health system. 

Russian President Vladimir Putin said last week that employees would observe “non-working days” from October 30 to November 7, during which they would still receive salaries. He said the period, in which four of the seven days are state holidays, could start earlier or be extended in certain regions. 

The rollout of Russia’s Sputnik V COVID-19 vaccine in Namibia was postponed Saturday by the country’s health ministry after the vaccine’s regulator in neighboring South Africa raised concerns about its safety for people at risk of HIV. 

The regulator said it would not approve an emergency-use application for the vaccine at this time because some studies suggest that the delivery system, known as a vector, used to inoculate people with the Sputnik V vaccine can cause men to be more susceptible to HIV. 

The vaccine’s manufacturer, Gamaleya Research Institute, said Namibia’s postponement was not based on scientific evidence. 

The Johns Hopkins Coronavirus Resource Center reported early Sunday a global count of 243.3 million COVID cases and almost 5 million COVID deaths. The center said 6.7 billion vaccines have been administered.

There will be cars at the Indianapolis Motor Speedway on Saturday but no drivers in sight as racing teams mark a milestone in autonomous vehicle development.

Nine single-seaters will take part in the Indy Autonomous Challenge (IAC), a competition with a $1 million prize that aims to prove “autonomous technology can work at extreme conditions,” said Paul Mitchell, CEO of co-organizer Energy Systems Network (ESN).

Cars will not race on the “Brickyard” track at the same time but will start one after the other — with the winner being the fastest over two full-speed laps.

Teams are made up of students from around the world. Each group was given the same Dallara IL-15 car, which looks like a small Formula One vehicle, and the same equipment, which includes sensors, cameras, GPS and radars.

On race day, it is not drivers that will make the difference — but about 40,000 lines of code programmed by each team. 

The software kickstarts the engine and a powerful computer wedged in the bucket where the driver usually sits.

The MIT-PITT-RW team, the only one made up entirely of students without supervision, got their car only six weeks ago.

Engineering student Nayana Suvarna, 22, does not yet have a driving license but was nonetheless reluctantly designated as team manager. 

“I didn’t know anything about car racing,” she said with a smile, “but I’m becoming a fan.”

The MIT-PITT-RW’s car hit 130 km/h in testing, but Suvarna believes it capable of overtaking 160 on Saturday. 

‘Generation of talent’

Other teams have gone much faster. 

The car belonging to the PoliMOVE team, a partnership between the universities of Alabama and Politecnico in Milan, drove past the pits at around 250 km/h on Thursday.

But the car skidded at the next turn, spinning 360 degrees before coming to a stop on the inside lawn. 

“It was a miracle we didn’t crash,” said Sergio Matteo Savaresi, professor at Politecnico.

There was no glitch to blame: only cold tires and a slight oversteer. 

“We actually reached the very limit of the car,” said Savaresi, who oversees the PoliMOVE team. 

“A professional driver at that speed with tires like these would have done exactly the same.”

The Robocar, made by manufacturer Roborace, has held the speed record for an autonomous car since 2019, clocking in at 282 km/h — but on a straight course, not a circuit.

The concept of self-driving cars has captured imaginations since the 1950s, but the tech needed to make them a reality has been boosted over the past five years.

Most big car manufacturers are working on autonomous driving projects, often in collaboration with tech giants such as Amazon, Microsoft or Cisco.

IAC participants do not see speed as the primary goal. 

“If people get used to seeing cars like these going 300 kilometers per hour… and they don’t crash,” said Savaresi, they may eventually think that such cars are safe “at 50 kilometers per hour.”

According to a Morning Consult survey published in September, 47 percent of Americans considered autonomous vehicles less safe than those driven by humans.

The race’s other goal is to enable tech sharing. 

Mitchell said several teams plan to make their code publicly available and open source after the competition.

“So, you’re going to take some of the most advanced AI algorithms ever developed for autonomous vehicles, and put it out there for industry, for startups, for other universities to build on.”

The project also aims to “develop a generation of talent,” Savaresi said.

“The people who are competing in this challenge are going to go and start companies, they’re going to go work for companies. And so I think the innovations from this competition will live on for many years.”

U.N. agencies are preparing to launch a polio vaccination campaign for all children under 5 in Afghanistan, a country where the potentially crippling disease persists despite a more than three-decade-long campaign that has nearly eradicated it worldwide.

Vaccine doses will begin to be administered in Afghanistan on November 8 for the first time in three years, now that the country’s new Taliban government has granted approval.

“This is a huge development that now we can go all across Afghanistan and deliver the vaccine house to house,” Dr. Hamid Jafari, the World Health Organization’s director of polio eradication for the Eastern Mediterranean region, told VOA.

Jafari described the upcoming campaign as “a real combination of excitement and extreme fear — excitement because it looks like a real opportunity to eradicate wild polio virus finally.”

Warning that the virus might still be “lurking in some hard-to-reach populations,” he said it’s critical that the WHO “maintain this momentum to vaccinate our children so that the virus has nowhere to go.”

“Both Afghanistan and Pakistan really actually need to switch gears,” Jafari declared.

Polio’s presence in Afghanistan and in neighboring Pakistan, where a U.N. polio vaccination effort begins in December, means the disease can still spread globally. Rotary International, which coordinates a global polio eradication program, predicts “hundreds of thousands of children could be paralyzed” if polio is not eliminated within 10 years.

The WHO announced the vaccination campaign on Tuesday, five days before the observance of World Polio Day, part of Rotary International’s Global Polio Eradication Initiative (GPEI).

Since the GPEI began in 1988, when there were 350,000 cases in 125 countries every year, polio cases have been cut by 99.9%, according to Rotary International.

The Taliban prohibited teams organized by the U.N. from conducting door-to-door vaccinations in parts of Afghanistan under their control over the past three years.

The ban and the recently ended war in Afghanistan prevented vaccines from being administered to 3.3 million of the country’s 10 million children over that period.

Taliban support

The Taliban did not comment on the agreement, but Jafari said, “The Taliban have always been supportive of polio eradication. … In fact, the polio education program started in Afghanistan when they were in government” previously from 1996 to 2001.

Jafari said the Taliban vaccination restriction “was imposed purely for considerations of security and the nature of conflict at the time, and that has now obviously changed drastically. So their commitment to support polio education remains, and this is an expression of that.”

He said the WHO has always “maintained dialogue” with the Taliban, in keeping with its “very neutral and impartial program” that enables children to be vaccinated “wherever they are.”

Carol Pandak, head of the PolioPlus program at Rotary International, said in an interview with VOA that GPEI continues to be successful, noting only two cases of polio have been detected in the recent past, one in Afghanistan and the other in Pakistan.

“We have gone the longest time ever since detecting a case of the wild poliovirus. We’ve reached almost nine months, but now is not the time to be complacent,” she cautioned. “We need to build on this progress. We need to continue immunizing children against polio, and we need to intensify our disease detection systems so that with so few cases we’ll be able to tell and prove that there is no polio circulating.”

Pandak said that while Rotary International was “cautiously optimistic” about the progress made this year, “we need to also focus on other diseases, especially for children, because some of their immunization campaigns have been canceled due to COVID. So we really need to be able to protect children from diseases such as polio, even during the COVID-19 pandemic.”

Earlier this month, WHO Director-General Tedros Adhanom Ghebreyesus celebrated Henrietta Lacks, a woman whose cervical cells were used to develop the polio vaccine, by acknowledging her “contribution to revolutionary advancements in medical science.”

The “HeLa cells” from Lacks, an African American, are the oldest and most used human cell line in existence. They were taken from her without permission at Johns Hopkins University in 1951 before her death, and their use has resulted in many other medical breakthroughs and research involving maladies such as AIDS and cancer.
