Defining the Anthropocene: nine sites are in the running to be given the ‘golden spike’ designation

Mentioning the Jurassic period, for instance, helps scientists to picture plants and animals that were alive during that time

“The Anthropocene represents an umbrella for all of these different changes that humans have made to the planet,”

Typically, researchers will agree that a specific change in Earth’s geology must be captured in the official timeline. The ICS will then determine which set of rock layers, called strata, best illustrates that change, and it will choose which layer marks its lower boundary

This is called the Global Stratotype Section and Point (GSSP), and it is defined by a signal, such as the first appearance of a fossil species, trapped in the rock, mud or other material. One location is chosen to represent the boundary, and researchers mark this site physically with a golden spike, to commemorate it.

“It’s a label,” says Colin Waters, who chairs the AWG and is a geologist at the University of Leicester, UK. “It’s a great way of summarizing a lot of concepts into one word.”

But the Anthropocene has posed problems. Geologists want to capture it in the timeline, but its beginning isn’t obvious in Earth’s strata, and signs of human activity have never before been part of the defining process.

“We had a vague idea about what it might be, [but] we didn’t know what kind of hard evidence would go into it.”

Years of debate among the group’s multidisciplinary members led them to identify a host of signals — radioactive isotopes from nuclear-bomb tests, ash from fossil-fuel combustion, microplastics, pesticides — that would be trapped in the strata of an Anthropocene-defining site. These began to appear in the early 1950s, when a booming human population started consuming materials and creating new ones faster than ever.

Why do some geologists oppose the Anthropocene as a new epoch?“It misrepresents what we do” in the ICS, says Stanley Finney, a stratigrapher at California State University, Long Beach, and secretary-general for the International Union of Geological Sciences (IUGS). The AWG is working backwards, Finney says: normally, geologists identify strata that should enter the geological timescale before considering a golden spike; in this case, they’re seeking out the lower boundary of an undefined set of geological layers.

Lucy Edwards, a palaeontologist who retired in 2008 from the Florence Bascom Geoscience Center in Reston, Virginia, agrees. For her, the strata that might define the Anthropocene do not yet exist because the proposed epoch is so young. “There is no geologic record of tomorrow,”

Edwards, Finney and other researchers have instead proposed calling the Anthropocene a geological ‘event’, a flexible term that can stretch in time, depending on human impact. “It’s all-encompassing,” Edwards says.

Zalasiewicz disagrees. “The word ‘event’ has been used and stretched to mean all kinds of things,” he says. “So simply calling something an event doesn’t give it any wider meaning.”

The same person who, on his own, wouldn’t ‘hurt a fly’ will not hesitate to set a government building on fire or rob a liquor store when part of an angry mass. The most mild-mannered of us can make the meanest comments as part of an online mob.

Once caught up in the maelstrom, it is extremely difficult to hold back: you see it as your duty to participate. Any act of lynching, ancient or modern, literal or on social media, displays this feature. ‘A murder shared with many others, which is not only safe and permitted, but indeed recommended, is irresistible to the great majority of men,’ writes Elias Canetti in Crowds and Power (1960).

The herd can also give its members a disproportionate sense of personal worth. No matter how empty or miserable their individual existence may otherwise be, belonging to a certain group makes them feel accepted and recognised – even respected. There is no hole in one’s personal life, no matter how big, that one’s intense devotion to one’s tribe cannot fill, no trauma that it does not seem to heal.

to a disoriented soul, they can offer a sense of fulfilment and recognition that neither family nor friends nor profession can supply. A crowd can be therapeutic in the same way in which a highly toxic substance can have curative powers.

Herding, then, engenders a paradoxical form of identity: you are somebody not despite the fact that you’ve melted into the crowd, but because of it

You will not be able to find yourself in the crowd, but that’s the least of your worries: you are now part of something that feels so much grander and nobler than your poor self

Your connection with the life of the herd not only fills an inner vacuum but adds a sense of purpose to your disoriented existence.

The primatologist Frans de Waal, who has studied the social and political behaviour of apes for decades, concludes in his book Mama’s Last Hug (2018) that primates are ‘made to be social’ – and ‘the same applies to us.’ Living in groups is ‘our main survival strategy’

we are all wired for herding. We herd all the time: when we make war as when we make peace, when we celebrate and when we mourn, we herd at work and on vacation. The herd is not out there somewhere, but we carry it within us. The herd is deeply seated in our mind.

As far as the practical conduct of our lives and our survival in the world are concerned, this is not a bad arrangement. Thanks to the herd in our minds, we find it easier to connect with others, to communicate and collaborate with them, and in general to live at ease with one another. Because of our herding behaviour, then, we stand a better chance to survive as members of a group than on our own

The trouble starts when we decide to use our mind against our biology. As when we employ our thinking not pragmatically, to make our existence in the world easier and more comfortable in some respect or another, but contemplatively, to see our situation in its naked condition, from the outside.

In such a situation, if we are to make any progress, we need to pull the herd out of our mind and set it firmly aside, exceedingly difficult as the task may be. This kind of radical thinking can be done only in the absence of the herd’s influence in its many forms: societal pressure, political partisanship, ideological bias, religious indoctrination, media-induced fads and fashions, intellectual mimetism, or any other -isms, for that matter.

a society’s established knowledge is the glue that keeps it together. Indeed, this unique concoction – a combination of pious lies and convenient half-truths, useful prejudices and self-flattering banalities – is what gives that society its specific cultural physiognomy and, ultimately, its sense of identity

By celebrating its established knowledge, that community celebrates itself. Which, for the sociologist Émile Durkheim, is the very definition of religion.

Musk seems willing to grant this power to racists, conspiracy theorists, and trolls. This isn’t great for reasonable people who want to have nuanced conversations on social media, but the joke has always been on them. Twitter isn’t that place, and it never will be.

one of Musk’s first moves after taking over was to fire the company’s head of policy—an individual who had publicly stated a commitment to both free speech and preventing abuse.

On Friday, Musk tweeted that Twitter would be “forming a content moderation council with widely diverse viewpoints,” noting that “no major content decisions [would] happen before that council convenes.” Just three hours later, replying to a question about lifting a suspension on The Daily Wire’s Jordan Peterson, Musk signaled that maybe that wasn’t exactly right; he tweeted: “Anyone suspended for minor & dubious reasons will be freed from Twitter jail.” He says he wants a democratic council, yet he’s also setting policy by decree.

Perhaps most depressingly, this behavior is quite familiar. As Techdirt’s Mike Masnick has pointed out, we are all stuck “watching Musk speed run the content moderation learning curve” and making the same mistakes that social-media executives made with their platforms in their first years at the helm.

Musk has charged himself with solving the central, seemingly intractable issue at the core of hundreds of years of debate about free speech. In the social-media era, no entity has managed to balance preserving both free speech and genuine open debate across the internet at scale.

Musk hasn’t just given himself a nearly impossible task; he’s also created conditions for his new company’s failure. By acting incoherently as a leader and lording the prospect of mass terminations over his employees, he’s created a dysfunctional and chaotic work environment for the people who will ultimately execute his changes to the platform

Functional Medicine isn't a protected title and a medical qualification isn't a prerequisite to practice. The result is an unregulated and disparate field, with medical doctors, nutritionists, naturopaths and homeopaths among the many practitioners.

Some other chronic illnesses the field claims to treat include heart disease, type 2 diabetes, irritable bowel syndrome, ulcerative colitis, depression, anxiety and arthritis

ll kinds of different reasons, some might have gluten issues, gut issues, others might have a deficiency causing neurological issues, MS is a symptom."

"There are components of Functional Medicine that absolutely lack an evidence base and there are practitioners of what they call Functional Medicine, they charge people for intravenous nutritional injections, they exaggerate claims, and that is professionally inappropriate, unethical and it lacks evidence.

On Dr Mark Hyman's view of MS he says, "there are a lot of terms put together there, all of which individually make a lot of sense, but put together in that way they do not.

"What does FM actually mean? It means nothing. It's a gift-gallop of words thrown together. It's criticised by advocates of evidence-based medicine because it's giving a veneer of scientific legitimacy to ideas that are considered pseudoscientific. For example, it'll take alternative medicine modalities like homeopathy and then call them 'bio-infusions' or something similar, rebranding it as something that works.

"It's a redundant name, real medicine is functional."

Next month the third annual Lifestyle and Functional Medical conference will take place in Salthill, Galway on November 3. Last year's event was attended by more than 500 people and featured a keynote address by honorary consultant cardiologist Dr Aseem Malhotra, author of bestselling The Pioppi Diet (which was named one of the top five worst celebrity diets to avoid in 2018 by the British Dietetic Foundation).

Dr David Robert Grimes is physicist and visiting fellow of Oxford and QUB. His research into cancer focuses on modelling tumour metabolism and radiation interactions. For Dr Grimes, the lack of definition, or "double-speak" as he puts it, in FM is troubling.

As well as the cost of appointments, FM practitioners commonly charge extra for tests. An omega finger prick test is around €100. A vitamin D test can cost upwards of €60, full thyroid panel more than €150 and a gut function test €400. Prices vary between practitioners.

"If I, as a GP, engaged in some of these behaviours I would be struck off." Specifically? "If I was recommending treatments that lacked an evidence base, or if I was promoting diagnostic tests which are expensive and lack an evidence base.

GPs engage every year in ongoing continuous professional development, I spend my evenings and my weekends outside of working hours attending educational events, small-group learning, large-group learning, engaging in research. This is an accusation that was levelled at the profession 30 years ago and then it was correct, but the profession has caught up…

"Obviously promoting wellness and healthy diet is very welcome but going beyond that and stating that certain aspects of 'functional medicine' can lead to reduced inflammation or prevent cancer, we have to be very careful about those claims.

Often the outcome of such tests are seemingly 'benign' prescriptions of vitamins or cleanses. However, dietitian Orla Walsh stresses that even these can have potentially harmful effects, especially on "vulnerable" patients, if not prescribed judiciously.

FM has five basic principles. 1. We are all genetically and biochemically unique so it treats the individual, not the disease. 2. It's science-based. 3. The body is intelligent and has the capacity for self-regulation. 4. The body has the ability to heal and prevent nearly all the diseases of ageing. 5. Health is not just the absence of disease, but a state of immense vitality.

She began her Functional Medicine career while training as a medical doctor and now travels the world working with high-profile clients. Dr McHale charges €425 for an initial consultation and €175 for follow-up appointments. Straightforward lab tests are €250 to €750, for complex cases testing fees can be up to €2,000.

"The term [Functional Medicine] tends to be bandied around quite a bit. Other things people say, such as 'functional nutritionist', can be misleading as a term. Many people are Functional Medicine practitioners but don't have any real medical background at all... I think regulation is always probably the best way forward."

"There's an awful lot to it in terms of biochemistry and physiology," she says. "You do need to have a very solid and well ingrained bio-chemistry background. A solely clinical background doesn't equip you with the knowledge to read a test.

"Evidence-base is the cornerstone of medicine and that has to be maintained. It becomes problematic in this area because you are looking at personalised medicine and that can be very difficult to evidence-base."

GP Christine Ritter travelled from England to attend the Galway conference last year with a view to integrating Functional Medicine into her practice.

"It was very motivating," she says. "Where it wasn't perhaps as strong was to find the evidence. The Functional Medicine people would say, 'we've done this study and this trial and we've used this supplement that was successful', but they can't show massive research data which might make it difficult to bring it into the mainstream.

"I also know the rigorous standard of trials we have in medicine they're not usually that great either, it's often driven by who's behind the trial and who's paying for it.

"Every approach that empowers patient to work on their destiny [is beneficial], but you'd have to be mindful that you're not missing any serious conditions."

Dr Hyman is working to grow the evidence-base for Functional Medicine worldwide. "The future is looking very bright," he says. "At the Cleveland Centre we're establishing a research base, building educational platforms, fellowships, residency programmes, rotations. We're advancing the field that's spreading across the world. We're seeing in China the development of a programme of Functional Medicine, South Africa, the UK, in London the Cleveland Clinic will hopefully have a Functional Medicine centre."

For Dr Mark Murphy regulation is a moot point as it can only apply once the field meets the standards of evidence-based medicine.

"Despite well intentioned calls for regulation, complementary and alternative medical therapies cannot be regulated," he says. "Only therapies that possess an evidence-base can enter our standard regulatory processes, including the Irish Medical Council, the Health Products Regulatory Authority and Irish advertising standards. In situations where complementary and alternative therapies develop an evidence base, they are no longer 'complementary and alternative', but in effect they become part of mainstream 'Medicine'.

l What are the principles?

"There's a huge variation between therapists, some are brilliant and some are okay, and some are ludicrous snake oil salesmen."

He is so concerned that patients' health and wealth are being put at risk by alternative therapies that earlier this year he joined Fine Gael TD Kate O'Connell and the Irish Cancer Society in introducing draft legislation earlier this year making it illegal to sell unproven treatments to cancer patients. Violators face jail and heavy fines.

Dr Grimes says criticism of variations in the standards of traditional medical research can be fair, however due to the weight of research it is ultimately self-correcting. He adds, "The reality is that good trials are transparent, independent and pre-registered.

"My involvement in shaping the Bill came from seeing first-hand the exploitation of patients and their families. Most patients undergoing treatment will take some alternative modalities in conjunction but a significant portion are talked out of their conventional medicine and seduced by false promises

What happened in 2012, when the oldest Gen-Z babies were in their middle teens? That was the year Facebook acquired Instagram and young people flocked to the latter site. It was also “the beginning of the selfie era.”

Mr. Haidt’s research, confirmed by that of others, shows that depression rates started to rise “all of a sudden” around 2013, “especially for teen girls,” but “it’s only Gen Z, not the older generations.” If you’d stopped collecting data in 2011, he says, you’d see little change from previous years. “By 2015 it’s an epidemic.” (His data are available in an open-source document.)

Mr. Haidt imagines “literally launching our children into outer space” and letting their bodies grow there: “They would come out deformed and broken. Their limbs wouldn’t be right. You can’t physically grow up in outer space. Human bodies can’t do that.” Yet “we basically do that to them socially. We launched them into outer space around the year 2012,” he says, “and then we expect that they will grow up normally without having normal human experiences.”

He calls this phenomenon “compare and despair” and says: “It seems social because you’re communicating with people. But it’s performative. You don’t actually get social relationships. You get weak, fake social links.”

That meant the first social-media generation was one of “weakened kids” who “hadn’t practiced the skills of adulthood in a low-stakes environment” with other children. They were deprived of “the normal toughening, the normal strengthening, the normal anti-fragility.

Now, their childhood “is largely just through the phone. They no longer even hang out together.” Teenagers even drive less than earlier generations did.

Mr. Haidt especially worries about girls. By 2020 more than 25% of female teenagers had “a major depression.” The comparable number for boys was just under 9%.

The comparable numbers for millennials at the same age registered at half the Gen-Z rate: about 13% for girls and 5% for boys. “Kids are on their devices all the time,”

Most girls, by contrast, are drawn to “visual platforms,” Instagram and TikTok in particular. “Those are about display and performance. You post your perfect life, and then you flip through the photos of other girls who have a more perfect life, and you feel depressed.

Mr. Haidt says he has no antipathy toward the young, and he calls millennials “amazing.”

“Social media is incompatible with liberal democracy because it has moved conversation, and interaction, into the center of the Colosseum. We’re not there to talk to each other. We’re there to perform” before spectators who “want blood.”

To illustrate his point about Gen Z, Mr. Haidt challenges people to name young people today who are “really changing the world, who are doing big things that have an impact beyond their closed ecosystem.”

He can think of only two, neither of them American: Greta Thunberg, 19, the Swedish climate militant, and Malala Yousafzai, 25, the Pakistani advocate for female education

I’m predicting that they will be less effective, less impactful, than previous generations.” Why? “You should always keep your eye on whether people are in ‘discover mode’ or ‘defend mode.’ ” In the former mode, you seize opportunities to be creative. In the latter, “you’re not creative, you’re not future-thinking, you’re focused on threats in the present.”

University students who matriculated starting in 2014 or so have arrived on campus in defend mode: “Here they are in the safest, most welcoming, most inclusive, most antiracist places on the planet, but many of them were acting like they were entering some sort of dystopian, threatening, immoral world.”

56% of liberal women 18 to 29 responded affirmatively to the question: Has a doctor or other healthcare provider ever told you that you have a mental health condition? “Some of that,” Mr. Haidt says, “has to be just self-presentational,” meaning imagined.

This new ideology . . . valorizes victimhood. And if your sub-community motivates you to say you have an anxiety disorder, how is this going to affect you for the rest of your life?” He answers his own question: “You’re not going to take chances, you’re going to ask for accommodations, you’re going to play it safe, you’re not going to swing for the fences, you’re not going to start your own company.”

Whereas millennial women are doing well, “Gen-Z women, because they’re so anxious, are going to be less successful than Gen-Z men—and that’s saying a lot, because Gen-Z men are messed up, too.”

The problem, he says, is distinct to the U.S. and other English-speaking developed countries: “You don’t find it as much in Europe, and hardly at all in Asia.” Ideas that are “nurtured around American issues of race and gender spread instantly to the U.K. and Canada. But they don’t necessarily spread to France and Germany, China and Japan.”

something I hear from a lot of managers, that it’s very difficult to supervise their Gen-Z employees, that it’s very difficult to give them feedback.” That makes it hard for them to advance professionally by learning to do their jobs better.

“this could severely damage American capitalism.” When managers are “afraid to speak up honestly because they’ll be shamed on Twitter or Slack, then that organization becomes stupid.” Mr. Haidt says he’s “seen a lot of this, beginning in American universities in 2015. They all got stupid in the same way. They all implemented policies that backfire.”

Mr. Haidt, who describes himself as “a classical liberal like John Stuart Mill,” also laments the impact of social media on political discourse

Social media and selfies hit a generation that had led an overprotected childhood, in which the age at which children were allowed outside on their own by parents had risen from the norm of previous generations, 7 or 8, to between 10 and 12.

Is there a solution? “I’d raise the age of Internet adulthood to 16,” he says—“and enforce it.”

By contrast, “life went onto phone-based apps 10 years ago, and the protections we have for children are zero, absolutely zero.” The damage to Generation Z from social media “so vastly exceeds the damage from Covid that we’re going to have to act.”

Gen Z, he says, “is not in denial. They recognize that this app-based life is really bad for them.” He reports that they wish they had childhoods more like those of their parents, in which they could play outside and have adventur
