The Washington Post reports: Oceans last year reached their highest levels in three decades — with the rate of global sea level rise increasing around 35% higher than expected, according to a NASA-led analysis published Thursday... Last year's rate of average global sea level rise was 0.23 inches per year, higher than the expected 0.17 inches per year, NASA said in a news release.

The rate of global sea level rise follows a trend of rapidly increasing rates over the past 30 years. From 1993 to 2023, the rate of global sea level rise doubled, increasing from 0.08 inches per year to 0.18 inches, another NASA-led study showed. Overall, the global sea level has climbed by 4 inches since 1993.
More details from ABC News: Climate change was a major driver to an unexpected level of sea level rise in 2024, according to a new NASA analysis... The majority of the difference between predicted and actual sea level rise was attributed to thermal expansion — or the ocean waters expanding as they warm, researchers said. An unusual amount of ocean warming, combined with meltwater from land-based ice such as glaciers, led to the increase of sea level rise last year, according to NASA.

About two-thirds of sea level rise in recent years has resulted from the melting of ice sheets and glaciers, with a third coming from thermal expansion, according to NASA. In 2024, those metrics flipped, with two-thirds of the rise attributed to expanding ocean water and one-third attributed to contributions from melting ice. "With 2024 as the warmest year on record, Earth's expanding oceans are following suit, reaching their highest levels in three decades," said Nadya Vinogradova Shiffer, head of physical oceanography programs and the Integrated Earth System Observatory at NASA... Human-amplified climate change is the primary cause for present-day rising sea levels, climate research shows.

"A new four-lane highway cutting through tens of thousands of acres of protected Amazon rainforest is being built for the COP30 climate summit," reports the BBC, "in the Brazilian city of Belém."

The highway will ease traffic into the city, which will host over 50,000 people at the conference this November: The state government touts the highway's "sustainable" credentials, but some locals and conservationists are outraged at the environmental impact... Along the partially built road, lush rainforest towers on either side — a reminder of what was once there. Logs are piled high in the cleared land which stretches more than 13km (8 miles) through the rainforest into Belém.

Diggers and machines carve through the forest floor, paving over wetland to surface the road which will cut through a protected area... The road leaves two disconnected areas of protected forest. Scientists are concerned it will fragment the ecosystem and disrupt the movement of wildlife...

The state government of Pará had touted the idea of this highway, known as Avenida Liberdade, as early as 2012, but it had repeatedly been shelved because of environmental concerns. Now a host of infrastructure projects have been resurrected or approved to prepare the city for the COP summit.
But on the bright side, Adler Silveira, the state government's infrastructure secretary, said the highway would have wildlife crossings for animals to pass over, as well as climate-friendly bike lanes and solar-powered lighting...

"Why can't we each have our own AI software that runs locally," asks long-time Slashdot reader BrendaEM — and that doesn't steal the work of others.

Imagine a powerful-but-locally-hosted LLM that "doesn't spy... and no one else owns it." We download it, from souce-code if you like, install it, if we want. And it assists: us... No one gate-keeps it. It's not out to get us...

And this is important: because no one owns it, the AI software is ours and leaks no data anywhere — to no one, no company, for no political nor financial purpose. No one profits — but you!
Their longer original submission also asks a series of related questions — like why can't we have software without AI? (Along with "Why is AMD stamping AI on local-processors?" and "Should AI be crowned the ultimate hype?") But this question seems to be at the heart of their concern. "What future will anyone have if anything they really wanted to do — could be mimicked and sold by the ill-gotten work of others...?"

"Could local, open-source, AI software be the only answer to dishearten billionaire companies from taking and selling back to their customers — everything we have done? Could we not...instead — steal their dream?!"

Long-time Slashdot reader BenFenner writes: For the third time in recent memory, CloudFlare has blocked large swaths of niche browsers and their users from accessing web sites that CloudFlare gate-keeps. In the past these issues have been resolved quickly (within a week) and apologies issued with promises to do better. (See 2024-03-11, 2024-07-08, and 2025-01-30.)

This time around it has been over six weeks and CloudFlare has been unable or unwilling to fix the problem on their end, effectively stalling any progress on the matter with various tactics including asking browser developers to sign overarching NDAs.
That last link is an update posted today by Pale Moon's main developer: Our current situation remains unchanged: CloudFlare is still blocking our access to websites through the challenges, and the captcha/turnstile continues to hang the browser until our watchdog terminates the hung script after which it reloads and hangs again after a short pause (but allowing users to close the tab in that pause, at least). To say that this upsets me is an understatement. Other than deliberate intent or absolute incompetence, I see no reason for this to endure. Neither of those options are very flattering for CloudFlare.

I wish I had better news.
In a comment, Slashdot reader BenFenner shares a list posted by Pale Moon's developer of reportedly affected browsers:

Cities in Europe "are dramatically scaling back their relationship with the car," reports the Washington Post: They are removing parking spaces and creating dedicated bike lanes. They are installing cameras at the perimeter of urban centers and either charging the most-polluting vehicles or preventing them from entering. Some are going so far as to put entire neighborhoods off-limits to vehicles. In Norway, Oslo promotes "car-free livability." Paris Mayor Anne Hidalgo touts the "end of car dependence." And while those ideas might sound radical to car-loving Americans, they are fast becoming the norm across the Atlantic, where 340 European cities and towns — home to more than 150 million people — have implemented some kind of restrictions on personal car usage...

[V]irtually every major European city is imposing some kind of rule. Milan has a system similar to New York's, charging for access to the city core — while entirely banning older, highly polluting vehicles. London charges vehicles that don't meet emissions standards, in what it calls the "largest clean-air zone in the world." The programs are not just the purview of liberal Western Europe: Warsaw, Poland, and Sofia, Bulgaria, recently adopted similar schemes. Even little Italian villages have added vehicle restrictions to reinforce their historic feel. And the Netherlands just broke ground on a 12,000-person neighborhood that will be entirely car-free. The neighborhood, known as Merwede, will be connected by public transport to Utrecht, a medium-size city that — perhaps no surprise — has a low-emissions zone of its own...

Perhaps the most elaborate and transformative effort has come in Paris, where Anne Hidalgo was elected mayor in 2014. Since then, Paris has banned the most-polluting vehicles from the city, eliminated 50,000 parking spaces and added hundreds of miles of bike lanes. It turned a bank of the Seine from a busy artery into a pedestrian zone, and closed off the famed Rue de Rivoli to traffic... Journeys by car in Paris have dropped by about 45 percent since 1990. The city has now become a source for striking before-and-after photos: of clogged streets that have transitioned into tree-lined areas where people can walk and play.
In London government officials say inhalable particular matter has fallen, according to the article, while combustion-produced nitrogen dioxide "is 53% lower than it would have been without the restrictions."

Slashdot has run nearly a dozen stories about Michael Mann, one of America's most prominent climate scientists and a co-creator of the famous "hockey stick" graph of spiking temperatures. In 2012 Mann sued two bloggers for defamation — and last year Mann finally won more than $1 million, reports the Washington Post. "A jury found that two conservative commentators had defamed him by alleging that he was like a child molester in the way he had 'molested and tortured' climate data."

But "Now, a year after that ruling, the case has taken a turn that leaves Mann in the position of the one who owes money." On Wednesday, a judge sanctioned Mann's legal team for "bad-faith trial misconduct" for overstating how much the scientist lost in potential grant funding as a result of reputational harm. The lawyers had shown jurors a chart that listed one grant amount Mann didn't get at $9.7 million, though in other testimony Mann said it was worth $112,000. And when comparing Mann's grant income before and after the negative commentary, the lawyers cited a disparity of $2.8 million, but an amended calculation pegged it at $2.37 million.


The climate scientist's legal team said it was preparing to fight the setbacks in court. Peter J. Fontaine, one of Mann's attorneys, wrote in an email that Mann "believes that the court committed errors of fact and law and will pursue these matters further." Fontaine emphasized that the original decision — that Mann was defamed by the commentary — still stands. "We have reviewed the recent rulings by the D.C. Superior Court and are pleased to note that the court has upheld the jury's verdict," he said.

"Wind and solar energy generated more electricity in the U.S. than coal for the first time last year," reports the Wall Street Journal, "according to analysis from clean-energy think tank Ember.

"The two renewable energy sources accounted for 17% of the country's power mix while coal fell to a low of 15%, it said." Solar was the fastest-growing energy source, according to Ember's analysis of data from the U.S. Energy Information Administration, increasing 27% from the year before, while wind rose 7%... Natural gas generation increased 3.3% in 2024, according to Ember, and remains by far the largest source of electricity in the U.S., accounting for 43% of the mix...

California and Nevada both surpassed 30% annual share of solar in their electricity mix for the first time last year (32% and 30%, respectively). California's battery growth was key to its solar success. It installed 20% more battery capacity than it did solar capacity, which helped it transfer a significant share of its daytime solar to the evening. Texas installed more solar and battery capacity than even California.

Yet the growth of solar was uneven — 28 states generated less than 5% of their electricity from solar in 2024, highlighting significant untapped potential — even before adding battery storage.
The article includes this observation from Dave Jones, chief analyst at Ember. "The fall in battery costs is a gamechanger for how much solar the U.S. electricity grid could integrate in the near future."

Electrek notes that "After being stagnant for 14 years, electricity demand started rising in recent years and saw a 3% increase in 2024, marking the fifth-highest level of rise this century..." Natural gas grew three times more than the decline in coal, increasing power sector CO2 emissions slightly (0.7%). Coal fell by the second smallest amount since 2014, as gas and clean energy growth met rising electricity demand, whereas historically, they have replaced coal. Despite growing emissions, the carbon intensity of electricity continued to decline. The rise in power demand was much faster than the rise in power sector CO2 emissions, making each unit of electricity likely the cleanest it has ever been.

An anonymous reader quotes a report from Fortune: Younger Americans don't have enough saved to cover a single month of spending, showcasing their vulnerability should the economy head into a downturn. Members of the Gen Z generation -- people born after 1995 -- were spending twice the amount they had in savings on average in February, according to Bank of America Institute analysis of internal account and card data released Friday. The ratio has increased in the past two years, and is much higher than for other generations. In part that's because Gen Z consumers, many of whom still hold entry-level positions and make less than their older peers, tend to spend a bigger share of their incomes on necessities including rent and utilities. But they're also more likely to shell out on discretionary categories like travel and entertainment. Spending in non-essentials among that cohort is up more than 25% from a year ago -- substantially above the overall rate.

While the report noted that Gen Z workers are still garnering robust pay gains compared to older groups, it showcases a point of vulnerability as households' views of the economy dim. [...] The Bank of America report also pointed to a worsening labor market for younger Americans. The number of Gen Z households receiving unemployment benefits rose by nearly a third in the past year -- the most of any generation. It also noted that, with underemployment on the rise, that could have long-term career effects for that cohort.

The US government's tariff announcements have become a "big headache" for technology companies such as iPhone maker Apple and cloud service provider Amazon, their manufacturing partner Foxconn said on Friday, in a rare public admission of the disruption caused by President Donald Trump's erratic trade policy. Financial Times: "The issue of tariffs is something that is giving the CEOs of our customers a big headache now," chief executive Young Liu told investors on an earnings call. "Judging by the attitude and the approach we see the US government taking towards tariffs, it is very, very hard to predict how things will develop over the next year. So we can only concentrate on doing well what we can control."

Liu said the company's customers were "one after another" hatching plans for co-operating with Foxconn on manufacturing in the US. He declined to give details as those plans were not yet finalised, but said there should be "more and more" manufacturing in the US.

Breakthrough Energy, the climate group founded by Bill Gates, has laid off dozens of employees in the U.S. and Europe, eliminating its public policy and partnerships teams as it shifts away from advocacy work. Its investment and grantmaking divisions will remain unaffected. The Detroit News reports: Breakthrough Energy is an umbrella organization founded by Gates that houses various initiatives aimed at accelerating the clean energy transition. It also encompasses Breakthrough Energy Ventures, one of the biggest investors in early-stage climate technologies with stakes in more than 120 companies, as well as a grantmaking program for early-seed stage company founders and Breakthrough Catalyst, a funding platform focused on emergent climate technologies. None of those divisions of the group were impacted by cuts, which were reported earlier by the New York Times.

[...] "In the United States especially, the conversation about climate has been sidetracked by politics," Gates wrote in the introduction to his 2021 book. "Some days, it can seem as if we have little hope of getting anything done." The climate pullback is happening at the same time as the US cuts foreign aid, a field where Gates is also a major donor. His nonprofit, the Gates Foundation, operates with a budget of billions and has a strong focus on overseas development. "Bill Gates remains as committed as ever to advancing the clean energy innovations needed to address climate change," a Breakthrough Energy spokesperson said in an emailed statement. "His work in this area will continue and is focused on helping drive reliable affordable, clean energy solutions that will enable people everywhere to thrive."

On Wednesday, the EPA announced the agency will "undertake 31 historic actions in the greatest and most consequential day of deregulation in U.S. history..."

A new study published in the Journal of Geophysical Research Planets reveals that atmospheric gravity waves play a crucial role in driving latitudinal air currents on Mars, particularly at high altitudes. Phys.Org reports: The study applied methods developed to explore Earth's atmosphere to quantitatively estimate the influence of gravity waves on Mars' planetary circulation. [...] "On Earth, large-scale atmospheric waves caused by the planet's rotation, known as Rossby waves, are the primary influence on the way air circulates in the stratosphere, or the lower part of the middle atmosphere. But our study shows that on Mars, gravity waves (GWs) have a dominant effect at the mid and high latitudes of the middle atmosphere," said Professor Kaoru Sato from the Department of Earth and Planetary Science. "Rossby waves are large-scale atmospheric waves, or resolved waves, whereas GWs are unresolved waves, meaning they are too fine to be directly measured or modeled and must be estimated by more indirect means."

Not to be confused with gravitational waves from massive stellar bodies, GWs are an atmospheric phenomenon when a packet of air rises and falls due to variations in buoyancy. That oscillating motion is what gives rise to GWs. Due to the small-scale nature of them and the limitations of observational data, researchers have previously found it challenging to quantify their significance in the Martian atmosphere. So Sato and her team turned to the Ensemble Mars Atmosphere Reanalysis System (EMARS) dataset, produced by a range of space-based observations over many years, to analyze seasonal variations up there.

"We found something interesting, that GWs facilitate the rapid vertical transfer of angular momentum, significantly influencing the meridional, or north-south, in the middle atmosphere circulations on Mars," said graduate student Anzu Asumi. "It's interesting because it more closely resembles the behavior seen in Earth's mesosphere rather than in our stratosphere. This suggests existing Martian atmospheric circulation models may need to be refined to better incorporate these wave effects, potentially improving future climate and weather simulations."

Yale University has suspended a law scholar and pro-Palestinian activist after an AI-generated article from Jewish Onliner falsely linked her to a terrorist group. Gizmodo reports: Helyeh Doutaghi, the scholar at Yale Law School, told the New York Times that she is a "loud and proud" supporter of Palestinian rights. "I am not a member of any organization that would constitute a violation of U.S. law." The article that led to her suspension was published in Jewish Onliner, a Substack that says it is "empowered by A.I. capabilities." The website does not publish the names of its authors out of fear of harassment. Ironically, Doutaghi and Yale were reportedly the subject of intense harassment after Jewish Onliner published the article linking Doutaghi to terrorism by citing appearances she made at events sponsored by Samidoun, a pro-Palestinian group. [...]

Jewish Onliner is vague about how it uses AI to produce its articles, but the technology is known for making lots of mistakes and hallucinating information that is not true. It is quite possible that Jewish Onliner relied on AI to source information it used to write the article. That could open it up to liability if it did not perform fact-checking and due diligence on its writing. Besides the fact that Doutaghi says she is not a member of Samidoun, she attended events it sponsored that support Palestinian causes, Yale Law School said the allegations against her reflect "potential unlawful conduct."

Mozilla is urging Firefox users to update their browsers to version 128 or later (or ESR 115.13 for extended support users) before March 14, 2025, to avoid security risks and add-on disruptions caused by the expiration of a key root certificate. "On 14 March a root certificate (the resource used to prove an add-on was approved by Mozilla) will expire, meaning Firefox users on versions older than 128 (or ESR 115) will not be able to use their add-ons," warns a Mozilla blog post. "We want developers to be aware of this in case some of your users are on older versions of Firefox that may be impacted." BleepingComputer reports: A Mozilla support document explains that failing to update Firefox could expose users to significant security risks and practical issues, which, according to Mozilla, include:

- Malicious add-ons can compromise user data or privacy by bypassing security protections.
- Untrusted certificates may allow users to visit fraudulent or insecure websites without warning.
- Compromised password alerts may stop working, leaving users unaware of potential account breaches.

It is noted that the problem impacts Firefox on all platforms, including Windows, Android, Linux, and macOS, except for iOS, where there's an independent root certificate management system. Mozilla says that users relying on older versions of Firefox may continue using their browsers after the expiration of the certificate if they accept the security risks, but the software's performance and functionality may be severely impacted.

Ancient Slashdot reader Alain Williams shares a report from the BBC: Meta has won an emergency ruling in the US to temporarily stop a former director of Facebook from promoting or further distributing copies of her memoir. The book, Careless People by Sarah Wynn-Williams, who used to be the company's global public policy director, includes a series of critical claims about what she witnessed during her seven years working at Facebook.

Facebook's parent company, Meta, says the ruling -- which orders her to stop promotions "to the extent within her control" -- affirms that "the false and defamatory book should never have been published." The UK publisher Macmillan says it is "committed to upholding freedom of speech" and Ms Wynn-Williams' "right to tell her story." [You can also hear Ms Wynn-Williams interviewed in the BBC Radio 4 Media Show on March 12.]

An anonymous reader shares a report: Germany's foreign intelligence service in 2020 put at 80%-90% the likelihood that the coronavirus behind the COVID-19 pandemic was accidentally released from China's Wuhan Institute of Virology, two German newspapers reported on Wednesday.

According to a joint report by publications Die Zeit and Sueddeutscher Zeitung, Germany's spying agency BND had indications that the institute had conducted gain-of-function experiments, whereby viruses are modified to become more transmissible to humans for research purposes.

It also had indications that numerous violations of safety regulations had occurred at the lab, the papers said. The spy agency assessment's was based on an unspecified intelligence operation code-named "Saaremaa" as well as on publicly-available data. It had been commissioned by the office of Germany's chancellor at the time, Angela Merkel, but never published, the report said.

Mozilla has warned that the U.S. Department of Justice's proposed remedies in its antitrust case against Google would harm independent browsers and reduce competition in the browser market. The DOJ and several state attorneys general last week filed revised proposed remedies in the U.S. v. Google search case that would prohibit all search payments to browser developers, a move Mozilla says would disproportionately impact smaller players.

"These proposed remedies prohibiting search payments to small and independent browsers miss the bigger picture -- and the people who will suffer most are everyday internet users," said Mark Surman, President of Mozilla. Unlike Apple and Microsoft, which generate revenue from hardware and operating systems, Mozilla relies primarily on search revenue to fund browser development. Mozilla argues that cutting these payments would not solve search dominance but would instead strengthen the position of tech giants.

Mozilla also warned that the proposal threatens its ability to maintain Gecko, one of only three major browser engines alongside Google's Chromium and Apple's WebKit. "If we lose our ability to maintain Gecko, it's game over for an open, independent web," Surman said, noting that even Microsoft abandoned its browser engine in 2019. "If Mozilla is unable to sustain our browser engine, it would severely impact browser engine competition and mean the death of the open web as we know it -- essentially, creating a web where dominant players like Google and Apple, have even more control, not less."

Firefox serves 27 million monthly active users in the U.S. and nearly 205 million globally.

Britain's competition watchdog has concluded that Apple and Google are stifling competition in the UK mobile browser market, following an investigation by the Competition and Markets Authority (CMA). The inquiry found Apple's iOS policies particularly restrictive, requiring all browsers to use its WebKit engine while giving Safari preferential access to features.

Apple's practice of pre-installing Safari as the default browser also reduces awareness of alternatives, despite allowing users to change defaults. Google faces similar criticism for pre-installing Chrome on most Android devices, though investigators noted both companies have recently taken steps to facilitate browser switching. The probe identified Apple's revenue-sharing arrangement with Google -- which pays a significant share of search revenue to be the default iPhone search engine -- as "significantly reducing their financial incentives to compete."

Google says its new open-source AI model, Gemma 3, achieves nearly the same performance as DeepSeek AI's R1 while using just one Nvidia H100 GPU, compared to an estimated 32 for R1. ZDNet reports: Using "Elo" scores, a common measurement system used to rank chess and athletes, Google claims Gemma 3 comes within 98% of the score of DeepSeek's R1, 1338 versus 1363 for R1. That means R1 is superior to Gemma 3. However, based on Google's estimate, the search giant claims that it would take 32 of Nvidia's mainstream "H100" GPU chips to achieve R1's score, whereas Gemma 3 uses only one H100 GPU.

Google's balance of compute and Elo score is a "sweet spot," the company claims. In a blog post, Google bills the new program as "the most capable model you can run on a single GPU or TPU," referring to the company's custom AI chip, the "tensor processing unit." "Gemma 3 delivers state-of-the-art performance for its size, outperforming Llama-405B, DeepSeek-V3, and o3-mini in preliminary human preference evaluations on LMArena's leaderboard," the blog post relates, referring to the Elo scores. "This helps you to create engaging user experiences that can fit on a single GPU or TPU host."

Google's model also tops Meta's Llama 3's Elo score, which it estimates would require 16 GPUs. (Note that the numbers of H100 chips used by the competition are Google's estimate; DeepSeek AI has only disclosed an example of using 1,814 of Nvidia's less-powerful H800 GPUs to server answers with R1.) More detailed information is provided in a developer blog post on HuggingFace, where the Gemma 3 repository is offered.

According to The Verge, Sonos has abandoned its plans to release a streaming video player this year. From the report: The news was announced by the company's leadership during an all-hands call today. That product, codenamed Pinewood, was set to be Sonos' next major hardware launch. It was already deep into development and has spent months in beta testing. But now the team behind it will be reassigned to other projects as interim CEO Tom Conrad reprioritizes the company's future roadmap and continues what he hopes will be a turnaround from a bruising 2024. He told employees that a push into video from Sonos is off the table "for now." [...]

Pinewood was designed to offer many of the same streaming video apps as other devices on the market along with deep universal search and content aggregation. But as I reported last month, Sonos also intended for it to double as an HDMI switcher and support passthrough functionality for gaming consoles, 4K Blu-ray players, and more. The box was also set to allow new configurations of surround sound systems using Sonos' many speakers.

An anonymous reader quotes a report from the EFF: EFF is deeply saddened to learn of the passing of Mark Klein, a bona fide hero who risked civil liability and criminal prosecution to help expose a massive spying program that violated the rights of millions of Americans. Mark didn't set out to change the world. For 22 years, he was a telecommunications technician for AT&T, most of that in San Francisco. But he always had a strong sense of right and wrong and a commitment to privacy. When the New York Times reported in late 2005 that the NSA was engaging in spying inside the U.S., Mark realized that he had witnessed how it was happening. He also realized that the President was not telling Americans the truth about the program. And, though newly retired, he knew that he had to do something. He showed up at EFF's front door in early 2006 with a simple question: "Do you folks care about privacy?"

We did. And what Mark told us changed everything. Through his work, Mark had learned that the National Security Agency (NSA) had installed a secret, secure room at AT&T's central office in San Francisco, called Room 641A. Mark was assigned to connect circuits carrying Internet data to optical "splitters" that sat just outside of the secret NSA room but were hardwired into it. Those splitters -- as well as similar ones in cities around the U.S. -- made a copy of all data going through those circuits and delivered it into the secret room. Mark not only saw how it works, he had the documents to prove it. He brought us over a hundred pages of authenticated AT&T schematic diagrams and tables. Mark also shared this information with major media outlets, numerous Congressional staffers, and at least two senators personally. One, Senator Chris Dodd, took the floor of the Senate to acknowledge Mark as the great American hero he was.
