BAKU, AZERBAIJAN — In the sprawling pavilion section of the United Nations climate talks, where countries, nonprofits and tech companies use big, flashy signs to get the attention of the thousands of people walking through, small aqua and purple beverage cans sit conspicuously on a counter at the Singapore display.

Those who approach learn that the cans are beer — a brand call NEWBrew — and free for anybody who asks. But there is something not everybody who cracks one open finds out right away, if at all: the beer is made with treated wastewater.

“I didn’t know. I was really surprised,” said Ignace Urchil Lokouako Mbouamboua, an international relations student from Congo, who recently sipped one while taking a break from the conference.

“I can even suggest that they make more and more of this kind of beer,” added Mbouamboua with a smile, sharing it was his third day in a row he stopped for a can.

NEWBrew is made in Singapore with NEWater, the name of treated wastewater that’s part of a national campaign to conserve every drop in one of the world’s most water-starved places.

The drink, which some attendees jokingly call “sewage beer,” is one of many examples of climate- and environment-related innovations on display during this year’s climate talks, COP29, taking place in Azerbaijan. Highlighting the use of treated wastewater underscores one of the world’s most pressing problems as climate change accelerates: providing drinking water to a growing population.

For years, Singapore has been a leader in water management and innovations. The city-state island of 6 million people in Southeast Asia, one of the most densely populated countries, has no natural water sources. In addition to water imports from Malaysia, the other pillars of its national strategy are catchment, desalination and recycling. Authorities have said they need to ramp up all water sources, as demand is expected to double by 2065.

While drinking treated wastewater is a novelty for many at the climate conference, for Singaporeans it’s nothing new. National campaigns — from water conservation pleas to showing the wastewater recycling process — go back decades. In 2002, then-Prime Minister Goh Chok Tong was famously photographed drinking a bottle of NEWater after a tennis match, done to normalize its use.

Ong Tze-Ch’in, chief executive of the Public Utilities Board, Singapore’s national water agency, said NEWBrew was developed by a local brewery in 2018. The idea was to showcase treated wastewater at the country’s biennial International Water Week. The beer was next produced in 2022, 2023, then again this year.

“It’s part of the acceptance of the use of recycled water, which in general is a difficult topic,” said Ong. “We did many things to drive it.”

And is he happy with how it turned out? 

“I chose this flavor,” said Ong, adding that he was part of the group that worked with the brewery for this year’s version, a “modern pilsner.”

“You know, beer is always very subjective,” he added with a laugh.

After attending a panel on water management at the Singapore pavilion, Peter Rummel, director of infrastructure policy advancement at Bentley Systems, which creates infrastructure engineering software, stepped up to the counter and got a beer. Rummel told onlookers he was in a good position to judge beer, as he hailed from Munich, Germany, home to the Oktoberfest beer festival.

“It’s fresh, light, cool. It has a nice flavor,” said Rummel, while looking at the can.

Wee-Tuck Tan, managing director of the local brewery, The Brewerkz Group, said they have made about 5,000 liters, or roughly 15,000 cans, for each edition of NewBrew. He said they use the same process as with other beers, and the cost is also similar, about 7 Singaporean dollars (around $5 U.S.) per can when bought in a supermarket.

Wee-Tuck said he believes the beer has shifted how some in Singapore view NEWater.

“They think it tastes funny,” he said. “When put into a beer, it changes the mindset. Most people can’t tell the difference.”

As problems with water scarcity grow, there is increasing embrace of the use of treated wastewater, said Saroj Kumar Jha, the World Bank Group’s global water department director, who participated in the water management panel in the Singapore pavilion. Traveling to over 50 countries in the last two years, he said leaders have frequently told him it’s important not to use the term “wastewater,” and instead call it “used water.”

After the panel concluded, Jha and the other panelists opened NEWBrews and toasted.

“It’s really good,” said Jha. “It’s the fourth time I’ve had it.”

“This year,” he added with a laugh. “Not today.”

Chinese hackers are positioning themselves in U.S. critical infrastructure IT networks for a potential clash with the United States, a top American cybersecurity official said Friday.

Morgan Adamski, executive director of U.S. Cyber Command, said Chinese-linked cyber operations are aimed at gaining an advantage in case of a major conflict with the United States.

Officials have warned that China-linked hackers have compromised IT networks and taken steps to carry out disruptive attacks in the event of a conflict. Their activities include gaining access to key networks to enable potential disruptions such as manipulating heating, ventilation and air-conditioning systems in server rooms, or disrupting critical energy and water controls, U.S. officials said earlier this year.

Beijing routinely denies cyber operations targeting U.S. entities. The Chinese Embassy in Washington did not immediately respond to a request for comment.

Adamski was speaking to researchers at the Cyberwarcon security conference in Arlington, Virginia. On Thursday, U.S. Senator Mark Warner told The Washington Post a suspected China-linked hack on U.S. telecommunications firms was the worst telecom hack in U.S. history.

That cyber espionage operation, dubbed “Salt Typhoon,” has included stolen call records data, compromised communications of top officials of both major U.S. presidential campaigns before the November 5 election, and telecommunications information related to U.S. law enforcement requests, the FBI said recently.

The FBI and Cybersecurity and Infrastructure Security Agency are providing technical assistance and information to potential targets, the bureau said.

Adamski said Friday that the U.S. government has “executed globally synchronized activities, both offensively and defensively minded, that are laser-focused on degrading and disrupting PRC cyber operations worldwide.”

Public examples include exposing operations, sanctions, indictments, law enforcement actions and cybersecurity advisories, with input from multiple countries, Adamski said.

london — The mpox outbreak continues to represent a public health emergency, the World Health Organization said on Friday.

The WHO first declared the emergency in August, when an outbreak of a new form of mpox spread from the badly hit Democratic Republic of Congo to neighboring countries.

The WHO convened a meeting of its Emergency Committee and, agreeing with its advice, the WHO director-general has determined that the upsurge of mpox continues to constitute a public health emergency of international concern.

The decision is based on the rising number and continuing geographic spread of cases, operational challenges in the field and the need to mount and sustain a cohesive response across countries and partners, the WHO said.

Mpox is a viral infection that spreads through close contact and typically causes flu-like symptoms and pus-filled lesions. It is usually mild, but it can be lethal.

This year, there have been more than 46,000 suspected cases across Africa, mainly in Congo, and more than 1,000 suspected deaths.

The label of “public health emergency of international concern” is the WHO’s highest form of alert and was also applied to a global outbreak of a different form of mpox in 2022-2023.

The alert issued this year followed the spread of a new variant of the virus, called clade Ib.

Cases of this variant have been confirmed in the U.K., Germany, Sweden and India, among other countries.

In September, after facing criticism on moving too slowly on vaccines, the WHO cleared Bavarian Nordic’s vaccine for mpox and, earlier this month, listed Japan’s KM Biologics’ shot for emergency use.

BAKU, AZERBAIJAN — The COP29 climate summit ran into overtime on Friday after a draft deal that proposed developed nations take the lead in providing $250 billion per year by 2035 to help poorer nations drew criticism from all sides.

World governments represented at the summit in the Azerbaijan capital, Baku, are tasked with agreeing on a sweeping funding plan to tackle climate change, but the talks have been marked by division between wealthy governments resisting a costly outcome and developing nations pushing for more.

The two-week conference in the Caspian Sea city, which was to end Friday evening, spilled past its scheduled close as the wrangling continued, with expectations the $250 billion target could yet rise.

“I’m so mad. It’s ridiculous. Just ridiculous,” said Juan Carlos Monterrey Gomez, the special representative for climate change for Panama. He called the proposed amount too low. “It feels that the developed world wants the planet to burn.”

A European negotiator, meanwhile, told Reuters the figure in the draft deal released by the summit presidency was uncomfortably high and did not do enough to expand the number of countries contributing to the funding.

“No one is comfortable with the number, because it’s high and [there is] next to nothing on increasing contributor base,” the negotiator said.

Governments that would be expected to lead the financing include the European Union, Australia, the United States, Britain, Japan, Norway, Canada, New Zealand and Switzerland.

The draft invited developing countries to contribute voluntarily but emphasized that paying in climate finance would not affect their status as “developing” nations at the United Nations, a red line for countries such as China and Brazil.

“This is not at a landing ground yet, but at least we’re not up in the air without a map,” said Germany’s special climate envoy, Jennifer Morgan.

‘First reflection’

Negotiations have been clouded by uncertainty over the role of the United States in the deal after climate-change skeptic Donald Trump won the presidential election on November 5, promising to withdraw the world’s top historic greenhouse gas emitter from international climate efforts when he retakes office in January.

The Azerbaijani COP29 presidency described Friday’s text as a “first reflection” of what countries had said in consultations and expressed hope negotiators would find agreement soon.

Azerbaijan’s lead negotiator, Yalchin Rafiyev, told reporters the draft deal had room for improvement.

“It doesn’t correspond to our fair and ambitious goal, but we will continue to engage with the parties,” he said.

The draft also set a broader goal to raise $1.3 trillion in climate finance annually by 2035, which would include funding from all public and private sources.

That is in line with a recommendation from economists that developing countries have access to at least $1 trillion annually by the end of the decade. Those same economists criticized the current $250 billion core target as too low.

But filling the gap between government pledges and private ones could be tricky, negotiators have warned.

“This goal will need to be supported by ambitious bilateral action, MDB contributions and efforts to better mobilize private finance, among other critical factors,” a senior U.S. official said, referring to multilateral development banks.

The current climate finance commitment, $100 billion per year, ends in 2025. Without a new collective target agreed through the U.N. process, some of the poorer countries most vulnerable to the impact of climate change would have little assurance of the money they need.

That means such countries have an incentive to negotiate hard, but even those most unhappy have a reason not to walk away or block a deal.

“We are far away from the $1.3 trillion,” said M. Riaz Hamidullah, a Bangladeshi foreign office official. “It’s a bit like haggling in the fish market, which we do often in our part of the world.”

Hottest on record

U.N. Secretary-General Antonio Guterres returned to Baku from a G20 meeting in Brazil on Thursday, calling for a major push to get a deal and warning that “failure is not an option.”

The showdown over financing for developing countries comes in a year that scientists say is destined to be the hottest on record. Climate woes are stacking up in the wake of such extreme heat, raising cries for more funding to cope.

Widespread flooding has killed thousands across Africa this year, while deadly landslides have buried villages in Asia. Drought in South America has shrunk rivers — vital transport corridors — and livelihoods.

Developed countries, too, have not been spared. Torrential rain triggered floods in Valencia, Spain, last month that killed more than 200, and the United States has so far registered 24 billion-dollar disasters, just four fewer than last year.

WASHINGTON — The Federal Communications Commission voted on Thursday to propose new rules governing undersea internet cables in the face of growing security concerns, as part of a review of regulations on the links that handle nearly all the world’s online traffic.

The FCC voted 5-0 on proposed updates to address the national security concerns over the global network of more than 400 subsea cables that handle more than 98% of international internet traffic.

“With the expansion of data centers, rise of cloud computing, and increasing bandwidth demands of new large language models, these facilities are poised to grow even more critical,” FCC Chair Jessica Rosenworcel said.

Baltic nations said this week they are investigating whether the cutting of two fiber-optic undersea telecommunication cables in the Baltic Sea was sabotage.

Rosenworcel noted that in 2023 Taiwan accused two Chinese vessels of cutting the only two cables that support internet access on the Matsu Islands and Houthi attacks in the Red Sea may have been responsible for the cutting of three cables providing internet service to Europe and Asia.

“While the details of these incidents remain in dispute, what is clear is that these facilities — with locations that are openly published to prevent damage — are becoming a target,” Rosenworcel said.

The Chinese Embassy in Washington said “turning undersea cables into a political and security issue severely disrupts international market rules, threatens global digital connectivity and cybersecurity, and denies other countries, especially developing countries, the right to develop their undersea cable industry.”

The FCC is conducting its first major review since 2001 and proposing to bar foreign companies that have been denied telecommunications licenses on national security grounds from obtaining submarine cable landing licenses.

It also proposes to bar the use of equipment or services in those undersea cable facilities from companies on an FCC list of companies deemed to pose threats to U.S national security including Huawei, ZTE 000063.SZ 601728.SS, China Telecom 0728.HK and China Mobile 600941.SS.

FCC Commissioner Geoffrey Starks said the commission is considering whether to bar companies from getting undersea cable licenses that are on other lists like the Commerce Department’s Consolidated Screening List. “China has made no secret of its goal to control the market, and therefore the data that flows throughout the world,” Starks said.

Last month, a bipartisan group of eight U.S. senators called on President Joe Biden to undertake “a review of existing vulnerabilities to global undersea cable infrastructure, including the threat of sabotage by Russia and China.”

The United States has for years expressed concerns about China’s role in handling network traffic and potential for espionage.

Since 2020, U.S. regulators have been instrumental in the cancellation of four cables whose backers had wanted to link the United States with Hong Kong.

In June, the FCC advanced a proposal to boost the security of information transmitted across the internet after government agencies said a Chinese carrier misrouted traffic.

LAS VEGAS — Federal water officials made public on Wednesday what they called “necessary steps” for seven states and multiple tribes that use Colorado River water and hydropower to meet an August 2026 deadline for deciding how to manage the waterway in the future.

“Today, we show our collective work,” Bureau of Reclamation Commissioner Camille Calimlim Touton said as she outlined four proposals for action and one “no action” alternative that she and Biden’s government will leave for the incoming Trump Administration — with formal environmental assessments still to come and just 20 months to act.

The announcement offered no recommendation or decision about how to divvy up water from the river, which provides electricity to millions of homes and businesses, irrigates vast stretches of desert farmland and reaches kitchen faucets in cities including Denver, Salt Lake City, Albuquerque, Las Vegas, Phoenix and Los Angeles.

Instead it provided a bullet-point sample of elements from competing proposals submitted last March by three key river stakeholders: Upper Basin states Colorado, Utah, New Mexico and Wyoming, where most of the water originates; Lower Basin states California, Arizona and Nevada, which rely most on water captured by dams at lakes Powell and Mead; and more than two dozen Native American tribes with rights to river water.

“They’re not going to take the any of the proposals,” said Sarah Porter, director of the Kyl Center for Water Policy at Arizona State University. “The federal government put the components together in a different way … and modeled them to provide near-maximum flexibility for negotiations to continue.”

One alternative would have the government act to “protect critical infrastructure” including dams and oversee how much river water is delivered, relying on existing agreements during periods when demand outstrips supply. “But there would be no new delivery and storage mechanisms,” the announcement said.

A second option would add delivery and storage for Lake Powell and Lake Mead, along with “federal and non-federal storage” to boost system sustainability and flexibility “through a new approach to distributing” water during shortages.

The third, dubbed “cooperative conservation,” cited a proposal from advocates aimed at managing and gauging water releases from Lake Powell amid “shared contributions to sustain system integrity.”

And a fourth, hybrid proposal includes parts of Upper and Lower Basin and Tribal Nations plans, the announcement said. It would add delivery and storage for Powell and Mead, encourage conservation and agreements for water use among customers and “afford the Tribal and non-Tribal entities the same ability to use these mechanisms.”

The “no action” option does not meet the purpose of study but was included because it is required under the National Environmental Policy Act, the announcement said.

In 2026, legal agreements that apportion the river will expire. That means that amid the effects of climate change and more than 20 years of drought, river stakeholders and the federal government have just months to agree what to do.

“We still have a pretty wide gap between us,” Tom Buschatzke, Arizona’s main negotiator on the Colorado River, said in a conference call with reporters. He referred to positions of Upper Basin and Lower Basin states. Tribes including the Gila River Indian Community in Arizona have also been flexing their long-held water rights.

Buschatzke said he saw “some really positive elements” in the alternatives but needed time to review them in detail. “I think anything that could be done to move things forward on a faster track is a good thing,” he said.

Democratic U.S. Sen. John Hickenlooper of Colorado said in a statement the alternatives “underscore how serious a situation we’re facing on the Colorado River.”

“The only path forward is a collaborative, seven-state plan to solve the Colorado River crisis without taking this to court,” he said. “Otherwise, we’ll watch the river run dry while we sue each other.”

Wednesday’s announcement came two weeks after Democratic Vice President Kamala Harris lost the election to Republican former President Donald Trump, and two weeks ahead of a key meeting of the involved parties at Colorado River Water Users Association meetings in Las Vegas.

Kyle Roerink, executive director of the Great Basin Water Network advocacy group, said “snapshots” offered in the announcement “underscore the uncertainty that is swirling around future river management as a new administration prepares to take office.”

“The river needs basin-wide curtailments, agreements to make tribes whole, a moratorium on new dams and diversions, commitments for endangered species and new thinking about outdated infrastructure,” he said.

Buschatzke declined to speculate about whether Trump administration officials will pick up where Biden’s leaves off. But Porter, at the Kyl Center, said the announcement “shows an expectation of continuity.”

“The leadership is going to change, but there are a lot of people who have been working on this for a long time who will still be involved in the negotiations and modeling,” she said.

NEW YORK — Nick Pickles, the former head of global affairs at Elon Musk’s social media platform X, is joining forces with one of Musk’s rivals, his fellow OpenAI co-founder Sam Altman.

Pickles, who resigned from X in September, told Reuters on Wednesday that he will serve as chief policy officer for Altman’s Tools for Humanity, the company building the technology to support World Network, formerly known as Worldcoin.

Pickles’ old boss, Musk, and his new boss, Altman, founded ChatGPT creator OpenAI in 2015 but have since fallen out in a messy legal dispute.

World Network, which has faced scrutiny over its data collection, is ramping up efforts to scan people’s irises, using its “orb” devices, to create World ID.

The ID will serve as a digital passport to prove, in the online realm, that its holder is an actual human being as opposed to an AI bot.

Pickles told Reuters that AI is “on the cusp” of overtaking traditional online defenses to determine whether a user is a real person, such as Captcha puzzles. Once AI can blow through those barriers, trust on the Web will further disintegrate.

“It’s imminent,” said Pickles. “Throughout my time at X and at Twitter, one of the consistent issues that kept coming up is, ‘Is this a real account or a bot?'” He added: “I saw every day how this issue is going to be central to the future of online interaction.”

During his 10 years at X, formerly known as Twitter, Pickles served most recently as the company’s top ambassador to heads of state across the globe. In that capacity, he worked closely with policymakers and regulators to shape regulatory proposals, negotiate compliance and represent the company in global forums.

He received a promotion at X in July.

One month later, billionaire Musk sued OpenAI and Altman for allegedly violating contract provisions that would have put the public good ahead of profits.

Pickles declined to comment on the litigation.

Pickles said he was optimistic about the new regulatory framework likely to be ushered in by the administration of President-elect Donald Trump.

His priority, he said, is hiring a lobbyist in Washington.

U.S. regulators want a federal judge to break up Google to prevent the company from continuing to squash competition through its dominant search engine after a court found it had maintained an abusive monopoly over the past decade.

The proposed breakup floated in a 23-page document filed late Wednesday by the U.S. Department of Justice calls for sweeping punishments that would include a sale of Google’s industry-leading Chrome web browser and impose restrictions to prevent Android from favoring its own search engine.

A sale of Chrome “will permanently stop Google’s control of this critical search access point and allow rival search engines the ability to access the browser that for many users is a gateway to the internet,” Justice Department lawyers argued in their filing.

Although regulators stopped short of demanding Google sell Android too, they asserted the judge should make it clear the company could still be required to divest its smartphone operating system if its oversight committee continues to see evidence of misconduct.

The broad scope of the recommended penalties underscores how severely regulators operating under President Joe Biden’s administration believe Google should be punished following an August ruling by U.S. District Judge Amit Mehta that branded the company as a monopolist.

The Justice Department decision-makers who will inherit the case after President-elect Donald Trump takes office next year might not be as strident. The Washington, D.C., court hearings on Google’s punishment are scheduled to begin in April and Mehta is aiming to issue his final decision before Labor Day.

If Mehta embraces the government’s recommendations, Google would be forced to sell its 16-year-old Chrome browser within six months of the final ruling. But the company certainly would appeal any punishment, potentially prolonging a legal tussle that has dragged on for more than four years.

Besides seeking a Chrome spinoff and a corralling of the Android software, the Justice Department wants the judge to ban Google from forging multibillion-dollar deals to lock in its dominant search engine as the default option on Apple’s iPhone and other devices. It would also ban Google from favoring its own services, such as YouTube or its recently launched artificial intelligence platform, Gemini.

Regulators also want Google to license the search index data it collects from people’s queries to its rivals, giving them a better chance at competing with the tech giant. On the commercial side of its search engine, Google would be required to provide more transparency into how it sets the prices that advertisers pay to be listed near the top of some targeted search results.

Kent Walker, Google’s chief legal officer, lashed out at the Justice Department for pursuing “a radical interventionist agenda that would harm Americans and America’s global technology.” In a blog post, Walker warned the “overly broad proposal” would threaten personal privacy while undermining Google’s early leadership in artificial intelligence, “perhaps the most important innovation of our time.”

Wary of Google’s increasing use of artificial intelligence in its search results, regulators also advised Mehta to ensure websites will be able to shield their content from Google’s AI training techniques.

The measures, if they are ordered, threaten to upend a business expected to generate more than $300 billion in revenue this year.

“The playing field is not level because of Google’s conduct, and Google’s quality reflects the ill-gotten gains of an advantage illegally acquired,” the Justice Department asserted in its recommendations. “The remedy must close this gap and deprive Google of these advantages.”

It’s still possible that the Justice Department could ease off attempts to break up Google, especially if Trump takes the widely expected step of replacing Assistant Attorney General Jonathan Kanter, who was appointed by Biden to oversee the agency’s antitrust division.

Although the case targeting Google was originally filed during the final months of Trump’s first term in office, Kanter oversaw the high-profile trial that culminated in Mehta’s ruling against Google. Working in tandem with Federal Trade Commission Chair Lina Khan, Kanter took a get-tough stance against Big Tech that triggered other attempted crackdowns on industry powerhouses such as Apple and discouraged many business deals from getting done during the past four years.

Trump recently expressed concerns that a breakup might destroy Google but didn’t elaborate on alternative penalties he might have in mind. “What you can do without breaking it up is make sure it’s more fair,” Trump said last month. Matt Gaetz, the former Republican congressman that Trump nominated to be the next U.S. Attorney General, has previously called for the breakup of Big Tech companies.

Gaetz faces a tough confirmation hearing.

This latest filing gave Kanter and his team a final chance to spell out measures that they believe are needed to restore competition in search. It comes six weeks after Justice first floated the idea of a breakup in a preliminary outline of potential penalties.

But Kanter’s proposal is already raising questions about whether regulators seek to impose controls that extend beyond the issues covered in last year’s trial, and — by extension — Mehta’s ruling.

Banning the default search deals that Google now pays more than $26 billion annually to maintain was one of the main practices that troubled Mehta in his ruling.

It’s less clear whether the judge will embrace the Justice Department’s contention that Chrome needs to be spun out of Google and or Android should be completely walled off from its search engine.

“It is probably going a little beyond,” Syracuse University law professor Shubha Ghosh said of the Chrome breakup. “The remedies should match the harm, it should match the transgression. This does seem a little beyond that pale.”

Google rival DuckDuckGo, whose executives testified during last year’s trial, asserted the Justice Department is simply doing what needs to be done to rein in a brazen monopolist.

“Undoing Google’s overlapping and widespread illegal conduct over more than a decade requires more than contract restrictions: it requires a range of remedies to create enduring competition,” Kamyl Bazbaz, DuckDuckGo’s senior vice president of public affairs, said in a statement.

Trying to break up Google harks back to a similar punishment initially imposed on Microsoft a quarter century ago following another major antitrust trial that culminated in a federal judge deciding the software maker had illegally used his Windows operating system for PCs to stifle competition.

However, an appeals court overturned an order that would have broken up Microsoft, a precedent many experts believe will make Mehta reluctant to go down a similar road with the Google case.

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.
