World Health Organization data published in September showed there were twice as many cholera cases in 2022 than in 2021. Outbreaks were recorded in countries where cholera had been under control for years, including Yemen and Lebanon.

2. Mosquitoes on the march

Rising temperatures and frequent floods also unlock new places where disease-carrying insects thrive. The mosquitoes that carry the viruses that cause dengue fever and mala

Nor is the disease confined to developing countries. There are fears that it is spreading in southern Europe, partly owing to the warm weather. More than 8 billion people could be at risk of malaria and dengue fever by 2080, scientists have warned.

3. Human-animal contact

Many existing diseases will get more dangerous, but new illnesses could also emerge as people are increasingly forced into areas where there is wildlife. Diseases can jump from animals to humans. These diseases, such as Ebola, avian flu and Sars, are called “zoonoses” and they make up the majority of new illnesses.

Scientists have found that the climate crisis is helping to circulate diseases between species that previously did not encounter each other. As the planet heats up, many animal species are forced to move into new areas to find suitable conditions.

It has been estimated that zoonoses are responsible for as many as 2.5bn cases of human illness and 2.7m human deaths worldwide each year, and that animals have played a major part in nearly every major disease outbreak since 1970.

4. Severe weather events

Although governments are getting better at preparing for severe weather events, nine out of 10 deaths linked to weather disasters since 1970 happened in small island nations and developing countries in Africa, Asia and South America.

5. The air that we breathe

Outside air pollution has been linked to numerous cancers and diseases and is estimated to be responsible for more than 4m premature deaths globally each year.

Changing weather patterns are expected to make this already bad situation worse as more dust, rain and wildfire smoke are added to the mix. Children are especially likely to get sick from air pollution because their brains, lungs and other organs are still developing.

6. The psychological cost

Environmental deterioration has a knock-on effect on the economic and social systems that keep society productive and happy, setting in motion a downward spiral of psychological hardship.

If crops are destroyed during extreme weather events, children may get less nutritious food, the consumption of which is linked to psychological conditions such as anxiety and depression.

When people can’t get the help they need, they may self-medicate with alcohol or drugs, which in turn makes them more likely to engage in risky behaviour (such as unprotected sex) that could result in infections such as HIV, or illnesses that can result from spending time in crowded places, such as tuberculosis.

In 2021, scientists studying evidence of a potential link between heat exposure and mental health found a 2.2% increase in mental health-related mortality per 1C rise in temperature.

7. Salty water and perilous pregnancies

Drinking water is becoming saltier. One reason for this is that sea levels are rising, so there is more sea water flowing into rivers and other sources of fresh water during floods and tropical storms.

Taking in too much salt can lead to high blood pressure (hypertension). Over time, this condition damages the body’s veins, arteries and major organs (including the brain, heart, kidneys and eyes) since they’re working so much harder overall.

Hypertension is doubly dangerous for pregnant women and their babies

8. Food insecurity

More frequent and severe droughts and floods make it harder to grow the grains, fruit and vegetables that people need to eat to stay healthy. Small island states in the Caribbean, Atlantic, Pacific and Indian Ocean bear the brunt of the effects of the crisis, in part because most people live close to sea level.

As a result, people who live in one of the 39 small island nations are the most likely to die from one of the four main NCDs: cancer, diabetes, heart disease and lung disease.

9. The stress of extreme heat

The scorching temperatures this year broke records in Europe, China and North America. Heat is one of the most dangerous effects of the climate crisis and the top cause of weather-related deaths in the U

When it gets too hot, the body’s temperature rises faster than it can cool itself down, less blood flows to other organs, and the kidneys have to work harder. This puts strain on the heart and can lead to organ failure. Heatstroke is the most serious heat-related illness.

In particular, people whose jobs require long hours of physical labour in the sun face an increased risk of kidney disease as temperatures rise, research suggests. Repeated instances of heat stress can lead to permanent damage and chronic kidney disease.

In June, the Guardian revealed how young migrant workers were returning to Nepal with chronic kidney disease after working in extreme heat conditions in the Gulf and Malaysia. “One factor highlighted again and again is heat. Prolonged exposure to h

10. Millions on the move

It’s hard to predict exactly how many people will be on the move because of the climate crisis, but extreme weather events are likely to make conditions worse for the more than 100 million displaced people around the world.

If nothing changes, the number of people who need humanitarian aid to recover from floods, storms and droughts could double by 2050,

That means more than 200 million people will need aid annually. The displacement of millions of people also means cramped and often unsanitary living. For example, more than 900,000 Rohingya refugees live in makeshift shelters in Bangladesh, often built on unstable ground that’s prone to landslides.

“We should be very concerned,” Whittaker said. “We are outgunned in terms of lobbying power [from major tech companies] and in terms of the ability to put our weight on the decision-makers in Congress.”

“we shouldn’t just dismiss it” as a “toy.”

“I think that sentiment is dangerous, like just coming in and saying this is just a hype cycle,” she said. “They’re getting better at doing things like structured reasoning. We shouldn’t just dismiss that this is not going to be a danger.”

The executive branch is “concerned and they’re doing a lot regulatorily, but everyone admits the only real answer is legislative,” Schumer said of the administration.

The attorneys from the Federal Public Ministry say the time has come for Brazilian institutions to account for their role in slavery. They’ve called on Banco do Brasil to commit to some form of reparations.

The attorneys on Friday gave Banco do Brasil 15 days to publicly acknowledge its role in slavery and the slave trade and present plans for some form of reparations.

The bank does not deny its ties to slavery but has argued that it should not be held responsible for the sins of a society. It says it did not commit any crimes and should not be liable for the actions of those who worked for or funded the bank

Brazilians, particularly elites descended from European settlers, have historically preferred to think of their country as free of racism. “A racial democracy,” they boasted, where people could marry independent of skin color and race was defined less rigidly than in the United States.

That story, historians say, has largely obscured the primacy of slavery in Brazil’s genesis — and its enduring impact. Brazil imported around 5 million enslaved Africans — far more than any other country — accounting for roughly 40 percent of the entire trade

Nearly twice as many enslaved people were brought through a single wharf in Rio de Janeiro than arrived in all of the United States. It was the last country in the Americas, in 1888, to abolish slavery.

“Bring together capital that has found itself displaced from illicit trade and converge it into a center where the productive forces of the country could be fed,” Irineu Evangelista de Sousa, who reopened the bank, wrote in his autobiography. “This was the idea that came into my head.”

Banco do Brasil, which in 2023 reported $380.3 billion in assets and $5.8 billion in profits, according to Forbes. Chartered in 1808 by Portuguese King Dom João, the bank drew its foundational capital from taxes the crown imposed on sea trade, much of which involved slavery. The wealthy Rio elite — many of whom trafficked in enslaved Africans — were invited by the crown to finance the bank.

When the trade was outlawed in 1831, the bank’s ties to slavery didn’t diminish, historians and government attorneys say — they intensified. The bank closed for two decades but reopened in 1853 for the purpose of accumulating ill-gotten wealth, prosecutors and historians allege, most of it from the international slave trade.

“Brazil has never had a problem romanticizing its memory of slavery,” said Luciana Brito, a historian at the Federal University of Recôncavo da Bahia. “It likes to remember slavery as a means of producing a beautiful people, of one nation, as though it was a necessary evil.”

The openness with which he spoke of the scheme, historians say, betrays the extent to which the crime of slavery was normalized in elite Brazilian society.

Under pressure from the United Kingdom, Brazil begrudgingly signed on to an international campaign to abolish the international slave trade in 1831. But it did little to enforce it. More than 700,000 enslaved Africans were trafficked into the country until a more restrictive law was passed in 1850.

But that story, and so many others, was virtually unknown to Brazilians, said Thiago Campos, a historian at the Federal Fluminense University. So a group of historians began discussing earlier this year how to start a broader conversation.

Fourteen historians wrote a letter this autumn to government attorneys outlining what they knew of Banco do Brasil’s history and asking for a national debate on the matter. The attorneys with the Federal Public Ministry, who represent Brazilians in cases involving individual or social rights, took it even further: They called for reparations.

“Unfortunately, Brazil is very behind on this discussion,” he said. “I believe it will be likely that as we progress with this case, others will come forward, and we’ll have more discussion on this topic. It’s an important moment to put this on the national agenda.”

Google’s generative-AI-powered search is the true nightmare for publishers. Across the media world, Google generates nearly 40% of publishers’ traffic, accounting for the largest share of their “referrals,” according to a Wall Street Journal analysis of data from measurement firm SimilarWeb. 

“AI and large language models have the potential to destroy journalism and media brands as we know them,” said Mathias Döpfner, chairman and CEO of Axel Springer,

His company, one of Europe’s largest publishers and the owner of U.S. publications Politico and Business Insider, this week announced a deal to license its content to generative-AI specialist OpenAI.

publishers have seen enough to estimate that they will lose between 20% and 40% of their Google-generated traffic if anything resembling recent iterations rolls out widely. Google has said it is giving priority to sending traffic to publishers.

The rise of AI is the latest and most anxiety-inducing chapter in the long, uneasy marriage between Google and publishers, which have been bound to each other through a basic transaction: Google helps publishers be found by readers, and publishers give Google information—millions of pages of web content—to make its search engine useful.

Already, publishers are reeling from a major decline in traffic sourced from social-media sites, as both Meta and X, the former Twitter, have pulled away from distributing news.

, Google’s AI search was trained, in part, on their content and other material from across the web—without payment. 

Google’s view is that anything available on the open internet is fair game for training AI models. The company cites a legal doctrine that allows portions of a copyrighted work to be used without permission for cases such as criticism, news reporting or research.

The changes risk damaging website owners that produce the written material vital to both Google’s search engine and its powerful AI models.

“If Google kills too many publishers, it can’t build the LLM,”

Barry Diller, chairman of IAC and Expedia, said all major AI companies, including Google and rivals like OpenAI, have promised that they would continue to send traffic to publishers’ sites. “How they do it, they’ve been very clear to us and others, they don’t really know,” he said.

All of this has led Google and publishers to carry out an increasingly complex dialogue. In some meetings, Google is pitching the potential benefits of the other AI tools it is building, including one that would help with the writing and publishing of news articles

At the same time, publishers are seeking reassurances from Google that it will protect their businesses from an AI-powered search tool that will likely shrink their traffic, and they are making clear they expect to be paid for content used in AI training.

“Any attempts to estimate the traffic impact of our SGE experiment are entirely speculative at this stage as we continue to rapidly evolve the user experience and design, including how links are displayed, and we closely monitor internal data from our tests,” Reid said.

Many of IAC’s properties, like Brides, Investopedia and the Spruce, get more than 80% of their traffic from Google

Google began rolling out the AI search tool in May by letting users opt into testing. Using a chat interface that can understand longer queries in natural language, it aims to deliver what it calls “snapshots”—or summaries—of the answer, instead of the more link-heavy responses it has traditionally served up in search results. 

Google at first didn’t include links within the responses, instead placing them in boxes to the right of the passage. It later added in-line links following feedback from early users. Some more recent versions require users to click a button to expand the summary before getting links. Google doesn’t describe the links as source material but rather as corroboration of its summaries.

During Chinese President Xi Jinping’s recent visit to San Francisco, the Google AI search bot responded to the question “What did President Xi say?” with two quotes from his opening remarks. Users had to click on a little red arrow to expand the response and see a link to the CNBC story that the remarks were taken from. The CNBC story also sat over on the far right-hand side of the screen in an image box.

The same query in Google’s regular search engine turned up a different quote from Xi’s remarks, but a link to the NBC News article it came from was beneath the paragraph, atop a long list of news stories from other sources like CNN and PBS.

Google’s Reid said AI is the future of search and expects its new tool to result in more queries.

“The number of information needs in the world is not a fixed number,” she said. “It actually grows as information becomes more accessible, becomes easier, becomes more powerful in understanding it.”

Testing has suggested that AI isn’t the right tool for answering every query, she said.

Many publishers are opting to insert code in their websites to block AI tools from “crawling” them for content. But blocking Google is thorny, because publishers must allow their sites to be crawled in order to be indexed by its search engine—and therefore visible to users searching for their content.To some in the publishing world there was an implicit threat in Google’s policy: Let us train on your content or you’ll be hard to find on the internet.

If all of this sounds familiar, it’s because we basically saw this same environmental dynamic play out several years ago with tech’s last big obsession: Crypto and web3. In that case, Bitcoin emerged as the industry’s obvious environmental sore spot due to the vast amounts of energy needed to mine coins in its proof of work model. Some estimates suggest Bitocin alone requires more energy every year than Norway’s annual electricity consumption.

rs of criticism from environmental activists however led the crypto industry to make some changes. Ethereum, the second largest currency on the blockchain, officially switched last year to a proof of stake model which supporters claim could reduce its power usage by over 99%. Other smaller coins similarly were designed with energy efficiency in mind. In the grand scheme of things, large language models are still in their infancy and it’s far from certain how its environmental report card will play out.

But to understand why Republicans have died at higher rates, you can’t look at vaccine status alone. Congressional districts controlled by a trifecta of Republican leaders—state governor, Senate, and House—had an 11 percent higher death rate, according to the Lancet study. A likely explanation, the authors write, could be that in the post-vaccine era, those leaders chose policies and conveyed public-health messages that made their constituents more likely to die. Although we still can’t say these decisions led to higher death rates, the association alone is jarring.

One of the most compelling studies comes from researchers at Yale, who published their findings as a working paper in November. They link political party and excess-death rate—the percent increase in deaths above pre-COVID levels—among those registered as either Democrats or Republicans, providing a more granular view. They chose to analyze data from Florida and Ohio from before and after vaccines were available. Looking at the period before the vaccine,  researchers found a 1.6 percentage-point difference in excess death rate among Republicans and Democrats, with a higher rate among Republicans. But after vaccines became available, that gap widened dramatically to 10.4 percentage points, again with a higher Republican excess death rate. “When we compare individuals who are of the same age, who live in the same county in the same month of the pandemic, there are differences correlated with your political-party affiliation that emerge after vaccines are available,”

What’s most concerning about all of this is that partisan disparities in death rates were also apparent before COVID. People living in Republican jurisdictions have been at a health disadvantage for more than 20 years. From 2001 to 2019, the death rate in Democratic counties decreased by 22 percent, according to a recent study; in Republican counties, it declined by only 11 percent. In the same time period, the political gap in death rates increased sixfold.

over the decades, state policy decisions on health issues such as Medicaid, gun legislation, tobacco taxes, and, indeed, vaccines have likely had a stronger impact on state health trajectories than other factors

the long-term decline of health in red states indicates that there is an ongoing problem at a high level in Republican-led places, and that something has gone awry. “If you happen to live in certain states, your chances for living a long life are going to be much higher than if you’re an American living in a different state,”

o acknowledge how many Republicans didn’t have to die would mean giving credence to scientific and medical expertise. So long as America remains locked in a poisonous partisan battle in which science is wrongly dismissed as being associated with the left, the death toll will only rise.

a “builder class”—a brains trust of youngish idealists, which includes Patrick Collison, co-founder of Stripe, a payments firm valued at $74bn, and other (mostly white and male) techies, who are posing questions that go far beyond the usual interests of Silicon Valley’s titans. They include the future of man and machine, the constraints on economic growth, and the nature of government.

They share other similarities. Business provided them with their clout, but doesn’t seem to satisfy their ambition

The number of techno-billionaires in America (Mr Collison included) has more than doubled in a decade.

ome of them, like the Medicis in medieval Florence, are keen to use their money to bankroll the intellectual ferment

The other is Paul Graham, co-founder of Y Combinator, a startup accelerator, whose essays on everything from cities to politics are considered required reading on tech campuses.

Mr Altman puts it more optimistically: “The iPhone and cloud computing enabled a Cambrian explosion of new technology. Some things went right and some went wrong. But one thing that went weirdly right is a lot of people got rich and said ‘OK, now what?’”

A belief that with money and brains they can reboot social progress is the essence of this new mindset, making it resolutely upbeat

The question is: are the rest of them further evidence of the tech industry’s hubristic decadence? Or do they reflect the start of a welcome capacity for renewal?

Two well-known entrepreneurs from that era provided the intellectual seed capital for some of today’s techno nerds.

Mr Thiel, a would-be libertarian philosopher and investor

This cohort of eggheads starts from common ground: frustration with what they see as sluggish progress in the world around them.

Yet the impact could ultimately be positive. Frustrations with a sluggish society have encouraged them to put their money and brains to work on problems from science funding and the redistribution of wealth to entirely new universities. Their exaltation of science may encourage a greater focus on hard tech

the rationalist movement has hit the mainstream. The result is a fascination with big ideas that its advocates believe goes beyond simply rose-tinted tech utopianism

A burgeoning example of this is “progress studies”, a movement that Mr Collison and Tyler Cowen, an economist and seer of the tech set, advocated for in an article in the Atlantic in 2019

Progress, they think, is a combination of economic, technological and cultural advancement—and deserves its own field of study

There are other examples of this expansive worldview. In an essay in 2021 Mr Altman set out a vision that he called “Moore’s Law for Everything”, based on similar logic to the semiconductor revolution. In it, he predicted that smart machines, building ever smarter replacements, would in the coming decades outcompete humans for work. This would create phenomenal wealth for some, obliterate wages for others, and require a vast overhaul of taxation and redistribution

His two bets, on OpenAI and nuclear fusion, have become fashionable of late—the former’s chatbot, ChatGPT, is all the rage. He has invested $375m in Helion, a company that aims to build a fusion reactor.

Mr Lonsdale, who shares a libertarian streak with Mr Thiel, has focused attention on trying to fix the shortcomings of society and government. In an essay this year called “In Defence of Us”, he argues against “historical nihilism”, or an excessive focus on the failures of the West.

With a soft spot for Roman philosophy, he has created the Cicero Institute in Austin that aims to inject free-market principles such as competition and transparency into public policy.

He is also bringing the startup culture to academia, backing a new place of learning called the University of Austin, which emphasises free speech.

All three have business ties to their mentors. As a teen, Mr Altman was part of the first cohort of founders in Mr Graham’s Y Combinator, which went on to back successes such as Airbnb and Dropbox. In 2014 he replaced him as its president, and for a while counted Mr Thiel as a partner (Mr Altman keeps an original manuscript of Mr Thiel’s book “Zero to One” in his library). Mr Thiel was also an early backer of Stripe, founded by Mr Collison and his brother, John. Mr Graham saw promise in Patrick Collison while the latter was still at school. He was soon invited to join Y Combinator. Mr Graham remains a fan: “If you dropped Patrick on a desert island, he would figure out how to reproduce the Industrial Revolution,”

While at university, Mr Lonsdale edited the Stanford Review, a contrarian publication co-founded by Mr Thiel. He went on to work for his mentor and the two men eventually helped found Palantir. He still calls Mr Thiel “a genius”—though he claims these days to be less “cynical” than his guru.

“The tech industry has always told these grand stories about itself,” says Adrian Daub of Stanford University and author of the book, “What Tech Calls Thinking”. Mr Daub sees it as a way of convincing recruits and investors to bet on their risky projects. “It’s incredibly convenient for their business models.”

In the 2000s Mr Thiel supported the emergence of a small community of online bloggers, self-named the “rationalists”, who were focused on removing cognitive biases from thinking (Mr Thiel has since distanced himself). That intellectual heritage dates even further back, to “cypherpunks”, who noodled about cryptography, as well as “extropians”, who believed in improving the human condition through life extensions

Silicon Valley has shown an uncanny ability to reinvent itself in the past.

“Over 80 technical papers published since January 2022,” LeCun responded. “What about you?”

To which Musk posted: “That’s nothing, you’re going soft. Try harder!

At stake are the hearts and minds of AI experts—academic and otherwise—needed to usher in the technology

“Join xAI,” LeCun wrote, “if you can stand a boss who:– claims that what you are working on will be solved next year (no pressure).– claims that what you are working on will kill everyone and must be stopped or paused (yay, vacation for 6 months!).– claims to want a ‘maximally rigorous pursuit of the truth’ but spews crazy-ass conspiracy theories on his own social platform.”

Some read Musk’s “science” dig as dismissing the role research has played for a generation of AI experts. For years, the Metas and Googles of the world have hired the top minds in AI from universities, indulging their desires to keep a foot in both worlds by allowing them to release their research publicly, while also trying to deploy products. 

For an academic such as LeCun, published research, whether peer-reviewed or not, allowed ideas to flourish and reputations to be built, which in turn helped build stars in the system.

LeCun has been at Meta since 2013 while serving as an NYU professor since 2003. His tweets suggest he subscribes to the philosophy that one’s work needs to be published—put through the rigors of being shown to be correct and reproducible—to really be considered science. 

“If you do research and don’t publish, it’s not Science,” he posted in a lengthy tweet Tuesday rebutting Musk. “If you never published your research but somehow developed it into a product, you might die rich,” he concluded. “But you’ll still be a bit bitter and largely forgotten.” 

After pushback, he later clarified in another post: “What I *AM* saying is that science progresses through the collision of ideas, verification, analysis, reproduction, and improvements. If you don’t publish your research *in some way* your research will likely have no impact.”

The spat inspired debate throughout the scientific community. “What is science?” Nature, a scientific journal, asked in a headline about the dust-up.

Others, such as Palmer Luckey, a former Facebook executive and founder of Anduril Industries, a defense startup, took issue with LeCun’s definition of science. “The extreme arrogance and elitism is what people have a problem with,” he tweeted.

For Musk, who prides himself on his physics-based viewpoint and likes to tout how he once aspired to work at a particle accelerator in pursuit of the universe’s big questions, LeCun’s definition of science might sound too ivory-tower. 

Musk has blamed universities for helping promote what he sees as overly liberal thinking and other symptoms of what he calls the Woke Mind Virus. 

Over the years, an appeal of working for Musk has been the impression that his companies move quickly, filled with engineers attracted to tackling hard problems and seeing their ideas put into practice.

“I’ve teamed up with Elon to see if we can actually apply these new technologies to really make a dent in our understanding of the universe,” Igor Babuschkin, an AI expert who worked at OpenAI and Google’s DeepMind, said last year as part of announcing xAI’s mission. 

The creation of xAI quickly sent ripples through the AI labor market, with one rival complaining it was hard to compete for potential candidates attracted to Musk and his reputation for creating value

that was before xAI’s latest round raised billions of dollars, putting its valuation at $24 billion, kicking off a new recruiting drive. 

It was already a seller’s market for AI talent, with estimates that there might be only a couple hundred people out there qualified to deal with certain pressing challenges in the industry and that top candidates can easily earn compensation packages worth $1 million or more

Since the launch, Musk has been quick to criticize competitors for what he perceived as liberal biases in rival AI chatbots. His pitch of xAI being the anti-woke bastion seems to have worked to attract some like-minded engineers.

As for Musk’s final response to LeCun’s defense of research, he posted a meme featuring Pepé Le Pew that read: “my honest reaction.”
