BAKU, Azerbaijan — Human-caused climate change made Atlantic hurricanes about 29 kilometers per hour (18 miles per hour) stronger in the last six years, a new scientific study found Wednesday. 

For most of the storms — 40 of them — the extra oomph from warmer oceans made the storms jump an entire hurricane category, according to the study published in the journal, Environmental Research: Climate. A Category 5 storm causes more than 400 times the damage of a minimal Category 1 hurricane, more than 140 times the damage of a minimal Category 3 hurricane and more than five times the damage of a minimal Category 4 storm, according to the National Oceanic and Atmospheric Administration. 

For three storms, including this month’s Rafael, the climate change factor goosed wind speed so much that the winds increased by two storm categories. 

This isn’t about more storms but increasing power from the worst ones, authors said. 

“We know that the intensity of these storms is causing a lot more catastrophic damage in general,” said lead study author Daniel Gifford, a climate scientist at Climate Central, which does research on global warming. “Damages do scale [up] with the intensity.” 

The effect was especially noticeable in stronger storms, including those that made it to the top of the Saffir-Simpson scale of storm intensity: Category 5, study authors said. The study looked at 2019 to 2023, but the authors then did a quick addition for the named storms this year, all of which had a bump up due to climate change. 

“We had two Category 5 storms here in 2024,” Gifford said. “Our analysis shows that we would have had zero Category 5 storms without human-caused climate change.” 

This year’s three most devastating storms — Beryl, Helene and Milton — increased by 29 kph (18 mph), 26 kph (16 mph) and 39 kph (24 mph) respectively because of climate change, the authors said. A different study by World Weather Attribution had deadly Helene’s wind speed increase by about 20 kph (13 mph), which is close, said Imperial College London climate scientist Friederike Otto, who coordinates the WWA team and praised the Climate Central work. 

“It absolutely makes sense from a fundamental standpoint that what’s going on is we’ve added more energy to the system,” National Oceanic and Atmospheric Administration chief Rick Spinrad said at United Nations climate talks in Baku, Azerbaijan. 

“The change is going to manifest in terms of what we’re already seeing. You look at Hurricane Helene, which was massive, 804 km [500 miles] across. We’re going to see changes in terms of the velocity of these storms. We’re going to see changes in terms of Hurricane Milton spawning so many tornadoes.” 

Since 2019, eight storms — 2019’s Humberto, 2020’s Zeta, 2021’s Sam and Larry, 2022’s Earl, 2023’s Franklin and 2024’s Isaac and Rafael — increased by at least 40 kph (25 mph) in wind speed. Humberto and Zeta gained the most: 50 kph (31 mph). 

In 85% of the storms studied in the last six years, the authors saw a fingerprint of climate change in storm strength, Gifford said. 

Warm water is the main fuel of hurricanes. The warmer the Atlantic, Caribbean and Gulf of Mexico get, the more potential energy goes into storms. Other factors — such as high-level crosswinds and dry air — can act to weaken hurricanes. 

The waters in the hurricane area have increased by 1.1 to 1.6 degrees Celsius (2 to 3 degrees Fahrenheit) in general and as much as 2.2 degrees C (4 degrees F) due to climate change, Gifford said. They know this because Climate Central has used scientifically accepted techniques to regularly track how much warmer oceans are because of the burning of coal, oil and natural gas. 

That technique basically uses computer simulations to create a fictional world with no human-caused warming and then compares it to current reality, with the difference being caused by greenhouse gases. They account for other factors, such as the lessening amount of sulfate pollution from marine shipping which had been counteracting a bit of the warming before the skies cleared up more. 

To go from warmer waters to stronger storms, the authors looked at a calculation called potential intensity, which is essentially the speed limit for any given storm based on the environmental conditions around it, Gifford said. 

MIT hurricane expert and meteorology professor Kerry Emanuel, who pioneered potential intensity measurements, wasn’t part of the study but said it makes sense. It shows the increase in storm strength that he predicted would happen 37 years ago, he said. 

Past studies have shown that climate change has made hurricanes intensify quicker, and move slower, which causes even more rain to be dumped.

NEW YORK — Distant, ancient galaxies are giving scientists more hints that a mysterious force called dark energy may not be what they thought.

Astronomers know that the universe is being pushed apart at an accelerating rate and they have puzzled for decades over what could possibly be speeding everything up. They theorize that a powerful, constant force is at play, one that fits nicely with the main mathematical model that describes how the universe behaves. But they can’t see it and they don’t know where it comes from, so they call it dark energy.

It is so vast it is thought to make up nearly 70% of the universe — while ordinary matter like all the stars and planets and people make up just 5%.

But findings published earlier this year by an international research collaboration of more than 900 scientists from around the globe yielded a major surprise. As the scientists analyzed how galaxies move they found that the force pushing or pulling them around did not seem to be constant. And the same group published a new, broader set of analyses Tuesday that yielded a similar answer.

“I did not think that such a result would happen in my lifetime,” said Mustapha Ishak-Boushaki, a cosmologist at the University of Texas at Dallas who is part of the collaboration.

Called the Dark Energy Spectroscopic Instrument, it uses a telescope based in Tucson, Arizona to create a three-dimensional map of the universe’s 11-billion-year history to see how galaxies have clustered throughout time and across space. That gives scientists information about how the universe evolved, and where it might be heading.

The map they are building would not make sense if dark energy were a constant force, as it is theorized. Instead, the energy appears to be changing or weakening over time. If that is indeed the case, it would upend astronomers’ standard cosmological model. It could mean that dark energy is very different than what scientists thought — or that there may be something else altogether going on.

“It’s a time of great excitement, and also some head-scratching and confusion,” said Bhuvnesh Jain, a cosmologist at the University of Pennsylvania who is not involved with the research.

The collaboration’s latest finding points to a possible explanation from an older theory: that across billions of years of cosmic history, the universe expanded and galaxies clustered as Einstein’s general relativity predicted.

The new findings aren’t definitive. Astronomers say they need more data to overturn a theory that seemed to fit together so well. They hope observations from other telescopes and new analyses of the new data over the next few years will determine whether the current view of dark energy stands or falls.

“The significance of this result right now is tantalizing,” said Robert Caldwell, a physicist at Dartmouth College who is not involved with the research, “but it’s not like a gold-plated measurement.”

There’s a lot riding on the answer. Because dark energy is the biggest component of the universe, its behavior determines the universe’s fate, explained David Spergel, an astrophysicist and president of the Simons Foundation. If dark energy is constant, the universe will continue to expand, forever getting colder and emptier. If it’s growing in strength, the universe will expand so speedily that it’ll destroy itself in what astronomers call the Big Rip.

“Not to panic. If this is what’s going on, it won’t happen for billions of years,” he said. “But we’d like to know about it.”

WASHINGTON — Pakistan’s top cleric has declared that virtual private networks, or VPNs, are unlawful, igniting a debate on privacy rights and access to information amid a government crackdown on the internet.

Allama Raghib Naeemi, head of the Council of Islamic Ideology (CII), issued a decree saying it makes no difference whether a VPN is registered or unregistered.

“If attempts are made to access indecent or immoral sites, character assassination is done, statements are being made against national security, or if various incidents of religious blasphemy are being spread through it, then [using] it would completely be un-Islamic,” he said.

A VPN protects online privacy by creating a secure connection and is used to access blocked content, protect data from hackers and support remote work or secure transactions.

Several internet service providers in Pakistan expressed concerns Tuesday over the possible imposition of blanket restrictions on VPNs, warning that the move would anger users and impact online businesses.

Shahzad Arshad, chairman of the Wireless and Internet Service Providers Association of Pakistan, said in a statement, “It is essential to recognize that blanket restrictions or sweeping narratives around tools like VPNs risk alienating segments of society, particularly those who rely on these tools for entirely legitimate purposes, such as IT exports, financial transactions, and academic research.”

Arshad, in reference to CII’s declaration, said technology is neutral and that how it is used determines whether it is aligned with ethics.

Amnesty Tech, part of Amnesty International, said last week on X that imposing restrictions on VPNs would amount to “violating the right to privacy under international law, restricting people’s access to information, and suppressing free expression.”

Qibla Ayaz, former chairman of CII, told VOA Deewa it seems as if a government agency has reached out to the religious body seeking its stance on the VPN issue.

“Similar requests were sent by the government in 2023,” he said. 

The CII is a constitutional body in Pakistan that advises the legislature on whether a certain law is repugnant to Islam, namely to the Quran and Sunna.

According to activists and experts, CII’s declarations on technology use are unwarranted and will only strengthen the government’s digital suppression of social media users.

Haroon Baloch, a Pakistani digital rights activist, believes the proposed restrictions on VPNs are aimed at suppressing political dissent.

“First, the government had compliance challenges with X. And when the platform did not agree with the government’s requests, then it banned X. And when X was available with the help of VPN, the government is planning to ban the VPN now,” Haroon told VOA.

Pakistan banned X in February and installed firewalls to restrict access to certain online content. But consumers are using VPNs to access restricted networks and content and to hide their identities and locations. 

Pakistan Army Chief General Asim Munir told a gathering at the Islamabad Policy Research Institute on November 16 that technology has played a pivotal role in the dissemination of information, but “the spread of misleading and incorrect information has become a significant challenge.”

In a speech to religious leaders in Islamabad earlier in August, Munir said, “Anarchy is spread through social media.”

A directive in October from the Interior Ministry asked the Pakistan Telecommunication Authority to block “illegal” VPNs that had not registered by the end of November.

The Interior Ministry charged in a letter to the Pakistan Telecommunication Authority, which oversees the internet and mobile industry and has broad powers over online content and the licensing of service providers, that terrorists are increasingly using VPNs to facilitate violent activities and financial transactions in Pakistan.

“Of late, an alarming fact has been identified, wherein VPNs are used by terrorists to obscure and conceal their communications,” the letter said, adding that pornography sites are frequently accessed using VPNs.

“These trends … warrant the prohibition of unauthorized virtual private networks in order to address critical threats,” the letter said.

The 2024 “Freedom on the Net” report published by Freedom House says the Pakistan Telecommunication Authority has historically implemented policies that undermine internet freedom, removed content without a transparent process and instituted wholesale bans on platforms.

CHEYENNE, Wyoming — A state judge on Monday struck down Wyoming’s overall ban on abortion and its first-in-the-nation explicit prohibition on the use of medication to end pregnancy. 

Since 2022, Teton County District Judge Melissa Owens has ruled consistently three times to block the laws while they were disputed in court. 

The decision marks another victory for abortion rights advocates after voters in seven states passed measures in support of access. 

One Wyoming law that Owens said violated women’s rights under the state constitution bans abortion except to protect a pregnant woman’s life or in cases involving rape and incest. The other made Wyoming the only state to explicitly ban abortion pills, though other states have instituted de facto bans on the medication by broadly prohibiting abortion. 

The laws were challenged by four women, including two obstetricians, and two nonprofit organizations. One of the groups, Wellspring Health Access, opened as the state’s first full-service abortion clinic in years in April 2023 following an arson attack in 2022. 

“This is a wonderful day for the citizens of Wyoming — and women everywhere who should have control over their own bodies,” Wellspring Health Access President Julie Burkhart said in a statement. 

The recent elections saw voters in Missouri clear the way to undo one of the nation’s most restrictive abortion bans in a series of victories for abortion rights advocates. Florida, Nebraska and South Dakota, meanwhile, defeated similar constitutional amendments, leaving bans in place. 

Abortion rights amendments also passed in Arizona, Colorado, Maryland and Montana. Nevada voters also approved an amendment in support of abortion rights, but they’ll need to pass it again in 2026 for it to take effect. Another that bans discrimination on the basis of “pregnancy outcomes” prevailed in New York. 

The abortion landscape underwent a seismic shift in 2022 when the U.S. Supreme Court overturned Roe v. Wade, a ruling that ended a nationwide right to abortion and cleared the way for bans to take effect in most Republican-controlled states. 

Currently, 13 states are enforcing bans on abortion at all stages of pregnancy, with limited exceptions, and four have bans that kick in at or about six weeks into pregnancy — often before women realize they’re pregnant. 

Nearly every ban has been challenged with a lawsuit. Courts have blocked enforcement of some restrictions, including bans throughout pregnancy in Utah and Wyoming. Judges struck down bans in Georgia and North Dakota in September 2024. Georgia’s Supreme Court ruled the next month that the ban there can be enforced while it considers the case. 

In the Wyoming case, the women and nonprofits who challenged the laws argued that the bans stood to harm their health, well-being and livelihoods, claims disputed by attorneys for the state. They also argued the bans violated a 2012 state constitutional amendment saying competent Wyoming residents have a right to make their own health care decisions. 

As she had done with previous rulings, Owens found merit in both arguments. The abortion bans “will undermine the integrity of the medical profession by hamstringing the ability of physicians to provide evidence-based medicine to their patients,” Owens ruled. 

The abortion laws impede the fundamental right of women to make health care decisions for an entire class of people — those who are pregnant — in violation of the constitutional amendment, Owens ruled.

California’s public health department reported a possible case of bird flu in a child with mild respiratory symptoms on Tuesday, but said there was no evidence of human-to-human transmission of the virus and that the child’s family members tested negative.

California officials said they have sent test specimens from the child to the U.S. Centers for Disease Control and Prevention for confirmation.

A CDC spokesperson said the agency is aware of the presumptive positive case of H5 avian influenza, is collaborating with the state’s investigation, and will provide further updates promptly. The agency has said the risk to the general public remains low.

Although human infections in the United States have been rare, bird flu has infected 53 people since April, according to the CDC, most recently a person in Oregon last week tied to a bird flu outbreak in a commercial poultry operation in the state.

In Canada, officials earlier this month reported that a teen infected with bird flu in British Columbia was in critical condition.

The child in California was in daycare with mild symptoms before the illness was reported, the state said.

Local health officials have contacted potentially exposed caregivers and families to check for symptoms and offer preventive treatment and testing if they become symptomatic.

The child and all close family members have been treated with preventive medication, the state said. The child had no known contact with an infected animal, but public health experts are investigating possible exposure to wild birds.

“It’s natural for people to be concerned, and we want to reinforce for parents, caregivers and families that based on the information and data we have, we don’t think the child was infectious,” said California health department director Dr. Tomas Aragon, adding, “and no human-to-human spread of bird flu has been documented in any country for more than 15 years.”

Most U.S. bird flu cases, including 26 in California, have occurred among farm workers working with poultry or dairy cows that were infected with the virus.

Because bird flu viruses can mutate and gain the ability to spread more easily between people, California public health officials said they are monitoring animal and human infections carefully.

The state urged residents to avoid contact with sick or dead wild birds and renewed the warning against consuming raw milk or raw milk products, which have not undergone pasteurization to inactivate the bird flu virus and other harmful pathogens.

London — As the COP29 climate summit in Baku, Azerbaijan enters its final days, there are growing frustrations over the apparent lack of progress toward securing a deal on climate finance, which is seen as a crucial step in reducing emissions and limiting global warming.

Mukhtar Babayev, Azerbaijan’s COP29 president, called on delegates to show more urgency.

“People have told me that they are concerned about the state of the negotiations,” Babayev told delegates Monday. “It’s time for them to move faster. This week we will welcome ministers from around the world as the negotiations reach their final stage.

“Politicians have the power to reach a fair and ambitious deal. They must deliver on this responsibility. They must engage immediately and constructively,” he said.

Climate finance

Money is at the center of the COP29 negotiations — or, in COP terms, climate finance. Who will pay for poorer countries to adapt to climate change and transition away from fossil fuels — and how much will it cost?

It’s hoped that the COP29 meeting will set an ambitious new funding target. Most estimates put the cost of climate finance in excess of $1 trillion every year. It’s reported that many richer nations are reluctant to agree to such an amount.

The current target of $100 billion annually, agreed in 2009, was met only in 2022.

‘Failed promises’

Bolivia’s representative at COP29, Diego Balanza — who chairs a negotiating bloc of developing nations — accused richer nations of a decade of failed promises.

“Our countries are suffering the impacts of climate change due largely to the historical emissions of developed countries. For us as developing countries, our people’s lives, their very survival and their livelihoods, are at stake,” Balanza told delegates in Baku.

He added that most of the climate finance so far has been provided through loans, not grants, which “has adverse implications for the macroeconomic stability of developing countries.”

Slow pace

Many observers have criticized the slow pace of negotiations in Baku. Mohamed Adow, director of the campaign group Power Shift Africa, accused the Azerbaijani hosts of a lack of direction.

“This has been one of the worst COPs — at least, one of the worst first weeks of COPs — that I have attended in the last 15 years,” Adow told VOA. “There has been very limited progress on climate finance and even on the rules around carbon markets and how the world is going to cut emissions.”

‘Theatrics’

Simon Stiell, the United Nations Climate Change executive secretary, on Monday called on parties to “cut the theatrics.”

“There is still a ton of work to do to ensure COP29 delivers. Parties need to be moving much faster towards landing zones. … I’ve been very blunt: climate finance is not charity. It is 100% in every nation’s interest to protect their economies and people from rampant climate impacts. Parties must wrap up less contentious issues early in the week, so there is enough time for the major political decisions,” Stiell said.

Emissions cuts

An ambitious COP29 deal on climate finance is meant to unlock the crucial next stage of negotiations. Ahead of next year’s COP30 in Brazil, all countries are due to deliver action plans on reducing greenhouse gas emissions, so-called ‘nationally determined contributions,’ with the goal of limiting global warming to 1.5°C above pre-industrial levels, a key target of the 2016 Paris Agreement on climate change.

On the current trajectory, scientists estimate the world is heading for a likely catastrophic 2.7°C of warming by the end of the century, which is predicted to cause widespread extreme weather and sea level rise.

Trump shadow

Adow, the director of Power Shift Africa, fears the COP29 negotiations are being overshadowed by the recent U.S. presidential election win for Donald Trump.

Trump pulled the United States out of the Paris Agreement on climate change during his first term. His successor, Joe Biden, re-entered the deal on his first day in office.

“I think the cloud hovering over these talks is the known unknown, around the election of Donald Trump and what the Trump administration is going to do. So, you have the rich world, that is actually hiding behind Trump — and not wanting to respond to the calls that we’ve had from the developing countries on the US$1.3 trillion that they require for climate finance,” Adow told VOA.

The COP29 talks are due to close on Friday. The deadline could be extended if a deal is in sight.

NAIROBI, KENYA — The spread of a mosquito in East Africa that thrives in urban areas and is immune to insecticide is fueling a surge in malaria that could reverse decades of progress against the disease, experts say.

Africa accounted for about 95% of the 249 million malaria cases and 608,000 deaths worldwide in 2022, according to the most recent data from the World Health Organization (WHO), which said children under 5 accounted for 80% of deaths in the region.

But the emergence of an invasive species of mosquito on the continent could massively increase those numbers. 

Anopheles stephensi is native to parts of South Asia and the Middle East but was spotted for the first time in the tiny Horn of Africa state of Djibouti in 2012.

Djibouti had all but eradicated malaria only to see it make a slow but steady return over the following years, hitting more than 70,000 cases in 2020. 

Then stephensi arrived in neighboring Ethiopia and WHO says it is key to an “unprecedented surge,” from 4.1 million malaria cases and 527 deaths last year to 7.3 million cases and 1,157 deaths between January 1 and October 20, 2024.

Unlike other species which are seasonal and prefer rural areas, stephensi thrives year-round in urban settings, breeding in man-made water storage tanks, roof gutters or even air conditioning units.

It appears to be highly resistant to insecticides, and bites earlier in the evening than other carriers. That means bed nets — up to now the prime weapon against malaria — may be much less effective.

“The invasion and spread of Anopheles stephensi has the potential to change the malaria landscape in Africa and reverse decades of progress we’ve made towards malaria control,” Meera Venkatesan, malaria division chief for USAID, told AFP.

More research is needed

The fear is that stephensi will infest dense cities like Mombasa on Kenya’s Indian Ocean coast and Sudan’s capital Khartoum, with one 2020 study warning it could eventually reach 126 million city-dwellers across Africa.

Only last month, Egypt was declared malaria-free by WHO after a century-long battle against the disease — a status that could be threatened by stephensi’s arrival.

Much remains unknown, however.

Stephensi was confirmed as present in Kenya in late 2022, but has so far stayed in hotter, dryer areas without reaching the high-altitude capital, Nairobi. 

“We don’t yet fully understand the biology and behavior of this mosquito,” Charles Mbogo, president of the Pan-African Mosquito Control Association, told AFP.

“Possibly it is climate-driven and requires high temperatures, but much more research is needed.”

He called for increased funding for capturing and testing mosquitos, and for educating the public on prevention measures such as covering water receptacles.

Multiplying threats

The spread of stephensi could dovetail with other worrying trends, including increased evidence of drug resistant malaria recorded in Uganda, Rwanda, Tanzania and Eritrea.

“The arrival of resistance is imminent,” said Dorothy Achu, WHO’s head of tropical and vector-borne diseases in Africa. 

WHO is working with countries to diversify treatment programmes to delay resistance, she said. 

A new malaria variant is also evading tests used to diagnose the disease. 

“The increased transmission that stephensi is driving could potentially help accelerate the spread of other threats, such as drug resistance or another mutation in the parasite that leads it to be less detectable by our most widely-used diagnostics,” said Venkatesan at USAID.

Another added challenge is the lack of coordination between African governments. 

Achu said WHO is working on “a more continental approach”. 

But Mbogo in Kenya said “more political will” was needed. 

“We share information as scientists with colleagues in neighbouring countries,” he said. “But we need to reach the higher level. We need cross-border collaborations, data-sharing.”

warsaw, poland — Poland’s health authorities on Monday urged polio vaccinations for children after the virus was detected in Warsaw’s sewage during regular tests this month.

The state Main Sanitary Inspectorate in a statement said the presence of the virus does not necessarily mean people have been sick, but those who have not been vaccinated against polio could be at risk. The vaccinations are free in Poland for people under 19.

New measures also include more intensive testing of Warsaw’s sewage, renewing the vaccination stocks and updating the list of children still unvaccinated. Polio is most often spread by contact with waste from an infected person or, less frequently, through contaminated water or food.

The polio virus mostly affects children under 5. Most people infected don’t have symptoms, but in severe cases, polio can invade the nervous system and cause paralysis within hours, according to the World Health Organization. It estimates that 1 in 200 polio cases results in permanent paralysis, usually of the legs.

Poland’s inspectorate said about 86% of the country’s 3-year-olds have been vaccinated against polio and that vaccinating at least 95% of children can prevent the spread of the virus. Poland has seen the rise of anti-vaccination movements among some parents, which has worried health officials.

The statement said Poland’s last case of polio was in 1984.

BAKU, Azerbaijan — United Nations climate talks resumed Monday with negotiators urged to make progress on a stalled-out deal that could see developing countries get more money to spend on clean energy and adapting to climate-charged weather extremes.

U.N. Climate Change executive secretary Simon Stiell called for countries to “cut the theatrics and get down to real business.”

“We will only get the job done if Parties are prepared to step forward in parallel, bringing us closer to common ground,” Stiell said to a room of delegates in Baku, Azerbaijan. “I know we can get this done.”

Climate and environment ministers from around the world have arrived at the summit to help push the talks forward.

“Politicians have the power to reach a fair and ambitious deal,” said COP29 President Mukhtar Babayev at a press conference at the venue. “They must deliver and engage immediately and constructively.”

Climate cash is still a sticking point

Talks in Baku are focused on getting more climate cash for developing countries to transition away from fossil fuels, adapt to climate change and pay for damages caused by extreme weather. But countries are far apart on how much money that will require.

A group of developing nations last week put the sum at $1.3 trillion, while rich countries are yet to name a figure. Several experts estimated that the money needed for climate finance is around $1 trillion.

“We all know it is never easy in politics and in international politics to talk about money, but the cost of action today is, as a matter of fact, much lower than the cost of inaction,” said Wopke Hoekstra, the EU climate commissioner at press conference.

“We will continue to lead to do our fair share and even more than our fair share, as we’ve always done,” he said. But Hoekstra added that “others have a responsibility to contribute based on their emissions and based on their economic growth too.”

Teresa Anderson, the Global Lead on Climate Justice at ActionAid International, was skeptical about rich countries’ intentions.

“The concern is that the pressure to add developing countries to the list of contributors is not, in fact, about raising more money for frontline countries,” Anderson said. “Rich countries are just trying to point the finger and have an excuse to provide less finance. That’s not the way to address runaway climate breakdown, and is a distraction from the real issues at stake.”

Rachel Cleetus from the Union of Concerned Scientists said $1 trillion in global climate funds “is going to look like a bargain five, 10 years from now.”

“We’re going to wonder why we didn’t take that and run with it,” she said, citing a multitude of costly recent extreme weather events from flooding in Spain to hurricanes Helene and Milton in the United States.

Robert Habeck, Germany’s climate and economic affairs minister said rich nations shouldn’t try to stop developing nations from producing more energy, but it has to come from cleaner sources.

“They have the same right to create same work, same education and health system,” he said. “On other hand, if we’re they are doing the same as we did for 100 years of burning fossil energy, that is completely messed up.”

Climate watchers keep an eye on Rio and Paris

Meanwhile, the world’s biggest decision makers are halfway around the world as another major summit convenes. Brazil is hosting the Group of 20 summit, which runs Nov. 18-19, bringing together many of the world’s largest economies. Climate change — among other major topics like rising global tensions and poverty — will be on the agenda.

COP President Babayev said the world “cannot succeed” in its climate goals without G20 nations.

“We urge them to use the G20 meeting to send a positive signal of their commitment to addressing the climate crisis. We want them to provide clear mandates to deliver,” he said.

Harjeet Singh, global engagement director for the Fossil Fuel Non-Proliferation Treaty Initiative, said G20 nations “cannot turn their backs on the reality of their historical emissions and the responsibility that comes with it.”

“They must commit to trillions in public finance,” he said.

Also on Monday, the Paris-based Organization for Economic Cooperation and Development has been mulling a proposal to cut public spending for foreign fossil fuel projects. The OECD — made up of 38 member countries including the United States, the United Kingdom, South Korea, Japan and Germany — are discussing a deal that could prevent up to $40 billion worth of carbon-polluting projects.

At COP29, activists are protesting the U.S., South Korea, Japan, and Turkey who they say are the key holdouts preventing the agreement in Paris from being finalized.

“It’s of critical importance that President Biden comes out in support. We know it’s really important that he lands a deal that Trump cannot undo. This can be really important for Biden’s legacy,” said Lauri van der Burg, Global Public Finance Lead at Oil Change international. “If he comes around, this will help mount pressure on other laggards including Korea, Turkey and Japan.”

DAEJEON, South Korea — Imagine a wheelchair equipped with wheels flexible enough to navigate all manner of obstacles from curbs to humps and even staircases.  

Or perhaps an unmanned delivery vehicle using the same wheels that takes the stairs to deliver food and groceries right to your door. 

This is what researchers from the Korea Institute of Machinery and Materials (KIMM) envision for their “morphing” wheel, which can roll over obstacles up to 1.3 times the height of its radius.  

Inspired by the surface tension of water droplets, it goes from solid to fluid when it encounters impediments. 

Other possible applications include robots that spy on the enemy in the battlefield. 

The KIMM team also hopes that morphing wheels will eventually be used with two- and four-legged robots – currently limited in movement efficiency and susceptible to vibration – that can carry payloads that need stable movement in industrial settings. 

“The goal is to make this viable for speed up to 100 kph, or the speed of an average car,” said Song Sung-hyuk, principal researcher at KIMM. 

Wheels developed for a similar purpose such as nonpneumatic or airless tires have flexibility but are limited in their ability to overcome obstacles, said Song, who is a member of KIMM’s AI robotics research team.  

The morphing wheel consists of an outer hoop of a chain and a series of spoke wires running through the hub. The stiffness of the spokes – and hence the wheel – is automatically regulated by a sensor as it reacts to the terrain. 

Song’s team demonstrated to Reuters a prototype wheelchair mounted on morphing wheels as it climbed stairs with 18-cm steps with a life-size dummy sitting in it. The team has also tested a device mounted with the wheel at speeds of up to 30 kph. 

The morphing wheel was featured on the cover of the journal Science Robotics in August.

BEIJING/HONG KONG — A 22-year-old Chinese woman’s account of how she was lured into the country’s illegal surrogacy industry before suffering a miscarriage went viral on Chinese social media this week and raised heated debates over women’s rights and social inequality. 

Surrogacy is banned in China, and authorities have vowed to severely crack down on illegal practices, including the buying and selling of sperm, egg and surrogacy services. 

The incident comes as Chinese authorities grapple with how to increase the country’s birth rate as more young couples put off having children or opt to have none. 

China’s population fell for a second consecutive year in 2023 and Beijing in October rallied local governments to direct resources towards fixing China’s population crisis to create a “birth-friendly” society.  

Zhang Jing, 22, told state-backed Phoenix TV magazine that she donated her eggs out of financial desperation and then agreed to “rent out her uterus” to be impregnated for a total of 30,000 yuan ($4,152).  

If she “successfully” delivered the baby, she would be paid a total of 240,000 yuan. At five months pregnant, she experienced severe complications and had to have an abortion.  

Zhang’s story amassed more than 86 million views and 10,000 comments on Chinese social media platform Weibo, with the hashtag “#2000s-born Surrogate Miscarriage Girl Speaks Out#.” 

The majority of comments strongly opposed surrogacy. Some warned that legalizing surrogacy in China could lead to increased competition that would lower compensation and further devalue women. 

“No woman could escape this if surrogacy were legalized,” one user wrote, while another said, “Legalizing surrogacy would drive down prices and commodify women.” 

Zhang’s story ignited calls for a more thorough crackdown on illegal surrogacy by authorities, with some commenters warning that allowing the black market to continue to operate could even normalize human organ trafficking.  

“Life should not be traded as a commodity,” one user wrote. “If this extends to the sale of organs, it will only get darker and darker, and women will have no future.” 

The incident comes a few weeks after a 28-year-old pregnant woman who acted as a surrogate in China’s southwestern city of Chengdu was allegedly abandoned by her surrogacy agency.

U.S. President-elect Donald Trump has selected Chris Wright, the founder of an oilfield services company, to lead the Energy Department, as his new administration continues to take shape. 

The transition team officially announced the choice on Saturday afternoon. On Friday, Trump announced a new National Energy Council to be led by his Interior Department pick, former North Dakota Governor Doug Burgum.

In this role, Burgum will direct a panel that crosses all executive branch agencies involved in energy permitting, production, generation, distribution, regulation and transportation, Trump said in a statement. As chairman of the National Energy Council, Burgum will have a seat on the National Security Council, the president-elect said. 

Wright, the CEO of Liberty Energy based in Denver, Colorado, has no political experience. He is an advocate for the oil and gas industry, including fracking. In 2019, he drank fracking liquid to show that it was not dangerous. 

According to a March 2024 report by the U.S. Energy Information Administration, the U.S. has produced more crude oil than any nation at any time, according to its International Energy Statistics, for the past six years in a row. Average monthly U.S. crude oil production established a monthly record high in December 2023 at more than 13.3 million barrels per day. 

Earlier announcements 

The Trump-Vance transition team announced Steven Cheung will return to the Trump White House as communications director. He held the same position for the Trump-Vance 2024 presidential campaign and served in the White House during Trump’s first term as director of strategic response.   

On Friday evening, Trump announced that his campaign press secretary, Karoline Leavitt, would be his White House press secretary. She served as assistant press secretary in his previous term in office. 

Trump has swiftly named an array of political loyalists to key Cabinet positions. Most of them are likely to win quick Senate approval after confirmation hearings.  

Having won majorities in both the U.S. House of Representatives and the U.S. Senate, Republicans are set to take full control of the U.S. government by the third week in January.  

“Republicans in the House and Senate have a mandate,” newly reelected House Speaker Mike Johnson said earlier this week. “The American people want us to implement and deliver that ‘America First’ agenda.” 

Trump will be sworn in as the country’s 47th president on January 20, two weeks after the new Congress has been seated.  

The 78-year-old Trump campaigned on a sweeping agenda that Democrats will be largely powerless to stop.  

Republicans will have a 53-47 edge in the Senate, and the tie-breaking vote of Vice President-elect JD Vance in the event of a 50-50 stalemate on any legislative proposal. Republicans have secured at least 218 seats in the 435-member House, pending the outcome of seven undecided elections for two-year terms.   

During his bid to win a second, nonconsecutive four-year term, Trump called for the massive deportation of millions of undocumented migrants living in the United States to their home countries, an extension and expansion of 2017 tax cuts that are set to expire at the end of 2025, further deregulation of businesses, a curb on climate controls, and prosecution of his political opponents.  

Senator John Thune of South Dakota, newly elected by his fellow Republicans as the Senate majority leader, said, “This Republican team is united. We are on one team. We are excited to reclaim the majority and to get to work with our colleagues in the House to enact President Trump’s agenda.”  

Trump also has called on Senate Republican leaders to allow him to make “recess appointments,” which could occur when the chamber is not in session and would erase the need for time-consuming and often contentious confirmation hearings.  

Despite the likelihood that most of his nominees will be approved, Trump this week named four who immediately drew disparaging assessments from several Democrats and some Republicans for their perceived lack of credentials.  

They are former Representative Matt Gaetz as attorney general; former Democratic congresswoman turned Republican Tulsi Gabbard as director of national intelligence; former junior military officer and Fox News host Pete Hegseth as defense secretary; and former presidential candidate and anti-vaccine activist Robert F. Kennedy Jr. to lead the Health and Human Services Department.  

The blowback presages tough confirmation fights for the four in the Senate, which reviews the appointments of top-level officials and then votes to confirm them or, on occasion, reject them, forcing the White House to make another choice.  

The appointment of Gaetz, 42, could prove particularly problematic, with some senators openly questioning whether he can win a 51-vote majority to assume the government’s top law enforcement position. 

A House ethics committee probe was in the final stages of investigating whether he engaged in sexual misconduct and illicit drug use when he announced his resignation from the chamber late Wednesday, ending the probe. 

The Justice Department that Gaetz hopes to lead had decided not to pursue criminal charges. Gaetz has denied all wrongdoing. 

Gabbard, 43, has been criticized for her lack of direct experience in intelligence and accused of disseminating pro-Russian disinformation. If confirmed, she would be tasked with overseeing 18 U.S. intelligence agencies. She won over Trump with her switch from being a one-time Democratic House member from Hawaii to changing parties and staunchly advocating for his election. 

Critics have assailed Hegseth, a 44-year-old decorated former military officer, as someone who lacks managerial experience in the business world. A weekend anchor on Fox News, he has voiced his opinions on military operations, including his opposition to women serving in combat roles. 

A descendant of the Kennedy family political dynasty, Kennedy, 70, for years has been one of the country’s most prominent proponents of anti-vaccine views. He also opposed water fluoridation. 

On Thursday, Trump also selected former Securities and Exchange Commission Chairman Jay Clayton to be Manhattan’s top federal prosecutor, and former Representative Doug Collins to be secretary of the Department of Veterans Affairs. 

Trump named one of his personal criminal defense attorneys, Todd Blanche, to be deputy attorney general, and another of his attorneys, D. John Sauer, to be solicitor general.
