When record heat feels strangely normal

Source: The Conversation – UK – By Will de Freitas, Environment + Energy Editor, The Conversation

Summer 2025 was the UK’s hottest on record, the Met Office announced this week. The news somehow felt both inevitable and surprising. There may have been four separate heatwaves, but for many this summer felt pretty normal.

This is because of “shifting baseline syndrome” and the way humans notice – or fail to notice – temperature change.


This roundup of The Conversation’s climate coverage comes from our award-winning weekly climate action newsletter. Every Wednesday, The Conversation’s environment editor writes Imagine, a short email that goes a little deeper into just one climate issue. Join the 45,000+ readers who’ve subscribed.


Academics have been warning about shifting baselines for decades: the idea that each generation takes the climate and ecosystems of its youth as the baseline or “normality”.

Back in 2020, Lizzie Jones, then a PhD researcher in conservation psychology at Royal Holloway, said this is why parents and grandparents should talk to children about the natural world of their youth.

“Even my parents”, she writes, “recall clouds of insects while they learned to drive, regular snowfall each winter and now rare bird species filling their back gardens.”

For people struggling to put environmental changes in context, local anecdotes like these can be more useful than news stories. “Older people hold a rich library of knowledge about the past,” says Jones, “and how their corner of the world has changed over the course of their lives.”

As time passes, losses accumulate or temperatures creep up. But because we reset our expectations every generation, the change feels ordinary. This is shifting baseline syndrome, and Jones says it leads us to “underestimate how much the environment has changed”.

She particularly focuses on wildlife changes:

“Whatever you or your generation grew up with is considered normal, but as species continue to go extinct and wild habitats are erased, your children will inherit a degraded environment and accept that as normal, and their children will normalise an even more impoverished natural world.”

Why grandparents should talk to children about the natural world of their youth


My own grandparents were born near Newcastle more than a century ago. Back then, red squirrels still dominated that part of the world but grey squirrels introduced from America were fast taking over. Skip forward two generations, and I’m not sure I’ve ever seen a red squirrel in the wild. My baseline is that squirrels are grey.

There’s something similar going on with birds in the UK. I grew up in west London and vividly remember as a teenager my first sighting of a bright green parakeet in Richmond Park. My friend Oscar told me a small colony had established themselves in the city’s suburbs. These days, I see these invasive parakeets (originally from the Himalayan foothills, say scientists) more than any bird aside from pigeons. They’re loud and annoying and keep taking food from native songbirds.

My children will never know a London without parakeets: that’s their baseline.

Altered perceptions

But it’s easy to spot when a chunky colourful parrot has muscled a tiny blue tit out of its usual feeding spot. It’s a lot harder to notice that the hottest summer day might now be 35°C rather than 31°C.

In part, that’s because climate change isn’t just altering the weather – it’s altering our perceptions.

Matthew Patterson is a climate scientist at the University of Reading. Writing in June last year, after supposedly cold and miserable weather still hadn’t moved the month much below the long-term temperature average, he noted that the UK has warmed so fast that: “We have come to normalise extreme heat, while relatively cold or even average conditions feel unusual and thus newsworthy.”

We’re also prone to very human biases here. Our collective memory of the weather in any given summer is hugely influenced by conditions during the daytime on perhaps ten weekends. Few people notice whether it was abnormally hot or cold at 3am on a Tuesday, but that’s part of the average too.

This may explain why the UK’s record hot summer still came as a surprise: we pay attention to outliers and recent events (August was cooler than July this year), not to the relentless upward creep of average temperatures.

Lost summers, wilder futures

History offers a sobering lesson in averages and outliers. During the little ice age between the 14th and 19th centuries, average global temperatures cooled by a few tenths of a degree. But that had a huge impact, especially in Europe: failed harvests, frozen rivers, famines and storms.

For climate historian Dagomar Degroot of Georgetown University in the US, this was a case of small global trends masking bigger local consequences. “The comparatively modest climate changes of the little ice age,” he says, “likely had profound local impacts.”

And if less than half a degree can do all that, what might two degrees of warming do in the near future?

Degroot does note that: “People who lived through the little ice age lacked perhaps the most important resource available today: the ability to learn from the long global history of human responses to climate change.”

Small climate changes can have devastating local consequences – it happened in the Little Ice Age


The little ice age teaches us how vulnerable we are to climate shifts, but we can reimagine the natural world rather than simply mourn its loss.

Back in 2018, Jones (the conservation psychologist), together with her colleagues Christopher Sandom and Owen Middleton of the University of Sussex, asked young people to imagine what a thriving natural world would look like:

“What they expressed was a desire to see ecosystems with not just more of the wildlife that’s currently there, but the return of species which have disappeared. There was also an undercurrent of sadness about litter and the present absence of wildlife, and hopes for more sustainable lifestyles in the future.”

This is why the authors say we should not simply accept shifting baseline syndrome, as it would mean “progressive damage to the natural world, even with our best efforts”.

Instead, they write, “By broadening our imagination and what we can expect from the environment, we can raise our ambitions for the natural world we leave to future generations.”

While memory loss hides decline, imagination can help reverse it.

These stories help explain the paradox of the low-key record-breaking summer. Shifting baselines make us forget the past. Human biases mean we notice cool rainy days more than creeping warmth. And history warns us that even small global changes have huge local effects.

Post-carbon

Lots of responses to our question about air conditioning last week.

Dave Pearson says: “When we were younger my wife and I lived in Chad without air conditioning for 10 years. In the hot season our living room would drop to 40 °C just before dawn, then the sun would rise…” He now has an AC unit in his living room: “We see it as a source of convenient comfort at this point, but potentially life-saving as we get older (and therefore more vulnerable) and heatwaves get hotter”

Marolin Watson says her “brick-built South-facing terrace house” tends to stay fairly cool. “However, with people increasingly being forced to live in flats that often rise a considerable distance into the air and may, depending on their orientation, catch the full sun for most or all of the day, I can see that air conditioners will be a necessity.”

Helen Wood says: “if you want air-conditioning, it should be only operated by battery powered by solar panels and not draw on the national grid”

Anne Heath Mennell grew up in Yorkshire and now lives in Australia. She points out “it is an efficient way to cool down, especially if powered by renewables”, but that people once “dreamed of balmy summers. Be careful what you wish for…”

An obvious question this week: what are some climate or environmental changes you have noticed in your lifetime? Don’t give me data: I want anecdotes.

What I’ve learned from photographing (almost) every British wildflower

The wildflowers of Britain include all manner of treasures – yet many people are only aware of a few, such as bluebells and foxgloves. A lot of its other flora are rare because of Britain’s location at the northern, western or even southern edges of their natural geographic – and hence climatic – ranges.

In fact, Britain has over 1,000 native species of wildflower, including 50 kinds of orchid, a few species like sundew that use sticky tentacles to eat insects, and others such as toothwort that live as parasites, plugging their roots into other plants to suck on their sap like botanical mosquitoes. There are even a few species, such as the ghost and bird’s-nest orchids, that extort all their food from soil fungi.


Many people think of plants as nice-looking greens. Essential for clean air, yes, but simple organisms. A step change in research is shaking up the way scientists think about plants: they are far more complex and more like us than you might imagine. This blossoming field of science is too delightful to do it justice in one or two stories.

This story is part of a series, Plant Curious, exploring scientific studies that challenge the way you view plantlife.

Pets on skinny jabs? Here’s how to help them lose weight naturally

Source: The Conversation – UK – By Jacqueline Boyd, Senior Lecturer in Animal Science, Nottingham Trent University

Losing weight is hard. Anyone who has tried to lose weight and keep it off will describe how difficult it can be. If your pet is a little more rotund than is healthy, then helping them regain and retain their waistline can be even trickier.

Drugs such as Ozempic (the brand name for the drug semaglutide) and Mounjaro (brand name for tirzepatide), both originally intended for treating type 2 diabetes in humans, have become increasingly used to support human weight loss. Given that estimates suggest that at least 50% of dogs and cats weighed at the vets are overweight, it’s unsurprising that the future potential to use drugs to support pet weight loss is now being explored.

It’s important to note that these weight management drugs are not currently in use for our pets, but it’s undeniable that pet obesity is a growing concern, and pharmaceutical companies are looking for solutions.

Just like us, carrying excess weight is associated with several health conditions for our pets, including osteoarthritis, inflammatory conditions, metabolic disorders and even shorter lives. This means that excess body weight is a significant health and welfare concern for our pets and might even be linked to our own expanding waistlines.

Unfortunately, our pets have a number of lifestyle challenges that can make weight gain more likely. Food that is tasty, freely available, highly digestible and high in calories means it is easy for our pets to eat more than they need. Combined with the use of frequent food training rewards and even accidental or guilt-based overfeeding, pets can quickly gain weight, which is then often difficult to lose.

Spaying and neutering have been very effective at reducing pet overpopulation and lowering the risk of some health problems like mammary tumours. However, these procedures can also make pets more likely to become overweight. To help prevent this, owners usually need to adjust their pets’ diets after surgery – most often by slightly reducing food portions and keeping track of their pets’ weight and body condition.

Some animals are more likely to gain weight because of their genetics, and this tendency has been unintentionally reinforced during domestication. Labrador retrievers, often called “foodies”, are a good example. Research shows that many Labs carry a gene mutation that affects an appetite-regulating molecule called pro-opiomelanocortin. Dogs with the mutation are more food-driven and more likely to gain weight than dogs without it.

Limited exercise is another big risk factor for weight gain. Many pets spend most of their time indoors or in the garden, which reduces their activity and energy use. Regular walking is good for dogs and their owners.

However, exercise alone won’t necessarily keep your pet lean. So, what can you do without the use of weight-loss drugs to help your pet?

Helping your pet keep a healthy weight naturally

Knowing what a healthy weight looks like for your pet is essential. One of the easiest tools for this is body condition scoring. Instead of just looking at the number on the scales, body condition scoring involves feeling your pet’s ribs, waist and tummy to check whether they’re too thin, too heavy or just right.

When used alongside regular weigh-ins, it gives you a clear picture of your pet’s overall health and helps you spot small changes early. Acting quickly on slight weight gain or loss – through diet, exercise, or a vet check – can make a big difference in keeping your pet fit and well.

Keeping active with your pet can help you both stay at a healthy weight. Playing games, adding fun activities, or just making sure your pet moves more each day are simple ways to support weight loss and keep it off in the long run.

What your pet eats is just as important as exercise when it comes to a healthy weight. A diet lower in calories to support steady weight loss is helpful for otherwise healthy pets. This can be done with foods that have less fat, moderate protein and more fibre. Some nutrients, like carnitine, which is often included in weight management diets, may also help the body use energy more effectively.

You can also look for low-calorie swaps that your pet enjoys. For example, many dogs love carrots and cucumbers as healthier treats.

If you are concerned about your pet’s weight, do seek veterinary advice and support. Keep records of their body weight, body condition, overall health, activity and even food intake. This can help you see where there might be easy wins for improving their health, wellbeing and even lifespan.

The choice is clear: rather than waiting for pharmaceutical solutions, we already have the tools we need to help our pets live their healthiest, happiest lives. The question isn’t whether we can help our pets maintain a healthy weight naturally – it’s whether we’re willing to make the commitment to do so.

Surzhyk: why Ukrainians are increasingly speaking a hybrid language that used to be a marker of rural backwardness

Source: The Conversation – UK – By Oleksandra Osypenko, PhD Candidate in Linguistics, Lancaster University

A Windows translator gives the option of Surzhyk. kpi.ua/surzhik

In Ukrainian dictionaries, the word “surzhyk” originally referred to a mix of grains – rye, wheat, barley and oats – or to flour made from a blend of these that was considered of lower quality. But its meaning morphed to mean a mixed or “impure” language – and today it refers to a blend of Ukrainian and Russian used by millions in Ukraine.

Often stigmatised in the past as a marker of rural backwardness, poor education or simply ignorance of Ukraine’s literary norms, the status of the Surzhyk language is now being reconsidered in wartime – not as a threat to Ukrainian identity, but as a way for native Russian speakers to communicate in a way that is more socially acceptable in a country at war with Russia.

Since the full-scale invasion of 2022, people in some central and eastern areas of Ukraine who might have primarily spoken Russian have been switching to Ukrainian, particularly in public. These are people who would have understood and occasionally used Surzhyk, but would have seen it as a form of Ukrainian “pidgin” – not to be used in formal situations. But now, it’s increasingly being used and any stigma that might have attached to it is slowly disappearing.

There has been debate about whether it’s a language in its own right, or a dialect or even slang. Most Ukrainian linguists tend to refer to it in English as an “idiom”. But it’s important to note that Surzhyk varies by region and is constantly evolving.

In the 1930s, it was heavily Russianised, reflecting Soviet language policies. More recently, after decades of Ukrainian revival, it has tilted in the other direction towards Ukrainian. And other influences are creeping in, especially from English. Words like “булінг” (buling, like the English “bullying”) and “донатити” (donatyty, meaning “to donate”) are slipping into everyday speech, showing how Surzhyk mirrors society’s shifting horizons.

But it is also a product of trauma and necessity. As Ukrainian writer Larissa Nitsoy notes, Ukrainians survived genocide – and they also survived linguicide. During the Soviet era, Russia made strenuous efforts to eradicate the Ukrainian language, punishing – often executing – those who spoke, wrote and taught in Ukrainian. To survive, they adapted.

Later, Surzhyk continued as a practical tool of social mobility. As Ukrainian-speaking villagers moved to Russian-dominated big cities in Ukraine for work or education, they adopted a hybrid idiom to “pass” as local. Laada Bilaniuk, a US-based anthropologist, calls this “urbanised-peasant Surzhyk” – a way of mimicking Russian without abandoning one’s Ukrainian linguistic roots.

In this sense, Surzhyk was both a survival strategy under Russian colonial rule, and an adaptation to urbanisation.

How widespread is Surzhyk?

In 2003, the Kyiv International Institute of Sociology (KIIS) estimated between 11% and 18% of Ukrainians spoke or wrote in Surzhyk – roughly one in seven people at the time. A more recent study of 104 students of the National Transport University in Kyiv in 2024 found that more than half of respondents (51%) admitted using some form of Surzhyk at home, and nearly one in five used it in messages with friends. Admittedly, the 2024 study was done on a much smaller scale, but the contrast is striking.

The question is: has the proportion of Surzhyk speakers really increased significantly – or simply the willingness to admit using it? Could it be that shame is giving way to recognition of Surzhyk as an acceptable tool for communication?

For decades, Surzhyk was a source of embarrassment. Nitsoy was voicing widespread Ukrainian nationalist views when she described it in 2021 as “a rape of the Ukrainian language by Russian”. Pavlo Hrytsenko, director of the Institute of the Ukrainian Language, argued that speaking Surzhyk signalled personal “underdevelopment”, a refusal to master the country’s literary language. Others were even more blunt, suggesting that: “By speaking Surzhyk, we humiliate ourselves.”

The assumption was that Surzhyk speakers leaned lazily toward Russian rather than making the effort to learn proper Ukrainian. These attitudes produced active campaigns to “correct” it, like the 2020 chatbot StopSurzhyk, which suggested literary alternatives for “improper” words.

This stigma was reinforced by the proportion of Ukrainian-Russian words and phrases that make up Surzhyk. Throughout the 20th century, Surzhyk was heavily Russianised, reflecting the dominance of Russian in public life. But more recently, and especially in the wake of Russia’s full-scale invasion of Ukraine in 2022, the balance has shifted. Surzhyk now carries more Ukrainian elements and has been increasingly viewed not as a regression, but a reversal.

A bridge for Russian speakers to Ukrainian

Today, Surzhyk is generally seen by Ukrainian scholars, writers and the wider public as transitional, even useful, and is often used by Russian speakers switching to Ukrainian.

Ukrainian linguistics experts argue that mocking or judging those speaking Surzhyk is misguided, because every language learner passes through such a stage, and that any Surzhyk is better than Russian.

Philologist Svitlana Kovtiukh likens the language to “slippers at home” – meaning that one might wear formal shoes in public but slip into something more comfortable in private. Ukrainians should be encouraged, according to Kovtiukh, to speak literary Ukrainian in official settings – as required by the Language Law – but be free to use Surzhyk in their personal life. What Soviet authorities once dismissed as “weeds” in the national language may actually be the streams that nourish it.

This reversal of perspective reflects a new hierarchy. Once a way for Ukrainian speakers to survive in a Russian-dominated world, Surzhyk is now a way back to Ukrainian for Russian speakers to Ukraine’s national language.

Once abominated by Ukrainians, it is increasingly seen as a tool of linguistic decolonisation. It’s both a practical way for Russian speakers to understand and be understood in Ukraine, and an alternative to what most Ukrainians see as the language of their oppressors.

OpenAI looks to online advertising deal – AI-driven ads will be hard for consumers to spot

Source: The Conversation – UK – By Stuart Mills, Assistant Professor of Economics, University of Leeds

AI says buy. SWKStock/Shutterstock

Making AI quicker, smarter and better is proving to be a very expensive business. Companies like OpenAI are investing billions of dollars in hardware, and the likes of Meta are offering top (human) talent huge salaries for their expertise.

So perhaps it’s no surprise that these businesses have started exploring new ways of making money as well as spending it.

OpenAI, for example, is exploring a partnership with Shopify, one of the world’s largest e-commerce platforms, which helps businesses manage online selling.

The reported deal between the two companies would see OpenAI receive a cut of any Shopify sales that result from recommendations provided by ChatGPT, creating a new revenue stream for OpenAI and more online traffic for Shopify.

But this relationship could be risky for consumers if OpenAI became incentivised to push people towards products, rather than offering genuinely objective recommendations. It might even push recommendations when users of ChatGPT are not looking to buy anything at all.

This situation reminds me of the early days of online advertising when Google was under pressure from shareholders to increase revenues, following the dot-com bubble. Google was (and still is) the world’s leading search engine, in part because it had the best algorithm. But the obvious path to generating revenue – advertising – posed a big dilemma.

Loading search results with adverts would put off users and weaken Google’s position. The company’s solution was to develop targeted advertising, matching ads to search queries to maintain relevance and quality.

Similarly, OpenAI will surely not just flood ChatGPT with links to products. If it did, the quality of its own product would decline, and users would quickly go elsewhere.

So, like Google, it needs to find a subtle way to influence people to shop.

Luckily for OpenAI, the sociable, text-based interface of a chatbot creates ample opportunities to use persuasive techniques to try to influence people’s behaviour.

Processing power of persuasion

One way of thinking about online persuasion is in terms of “metacognition”, the ability to think about thinking, which is very important in the world of sales.

Research suggests that when a customer has high metacognition skills, they are more likely to be sceptical of a salesperson’s tactics, and harder to persuade. When a salesperson has high metacognition, they are good at getting into a customer’s head and making a sale.

One theory of metacognition argues that high levels are influenced by how much sellers and customers know about a product, how much they know about persuasion, and how much they know about each other.

In all three cases, AI may have an advantage.

On any given topic, ChatGPT will “know” more about it than an average person. A particularly knowledgeable person might not get caught out. But nobody is an expert on everything, while ChatGPT can at least pretend to be (like any good salesperson).

AI large language models (known as LLMs) are also up to speed on the latest research on rhetoric, marketing and psychology. They can even identify deceptive sales techniques.

AI can also be tweaked to be persuasive. For instance, research has found that people are more likely to buy something when a salesperson or advert mirrors their personality. One study found that ChatGPT can accurately predict a person’s personality from relatively little information. Over time then, ChatGPT could be programmed to make predictions about us, and then start acting like us.

When it comes to knowledge about each other, most people probably know little about how AI language tools actually work. And if people are also unaware of the incentive AI companies may soon have to recommend products, these recommendations may be met with less scepticism, because an AI chatbot would seemingly have no motive to manipulate.

Chatting about products.

Meanwhile, like Google, companies such as OpenAI are gathering huge amounts of data about the people who use their software. Initially, this was to train future AI models. But these same data could be used to learn more about people, what makes them tick, and what makes them click “buy”.

Product recommendations from ChatGPT, Google or any other company are not inherently sinister. If data is used to suggest products people genuinely love, this can be helpful.

But being helpful is not the primary motivation here. Just as Google introduced ads because of financial pressure, deals like those between OpenAI and Shopify are a response to the economic pressures the AI industry is facing.

It is great if these systems recommend products a person wants to buy. But what might matter most to AI, regardless of the product, is that they buy it.

KPop Demon Hunters gives a glimpse into K-pop culture in South Korea

Source: The Conversation – UK – By Cholong Sung, Lecturer in Korean, SOAS, University of London

Thanks to the runaway global popularity of Netflix’s new animated film, KPop Demon Hunters, cinemas around the world have picked it up and are now screening a sing-along edition.

Huntr/x, the musical girl group featured in the story, has topped charts worldwide with their track Golden.

As the film smashes records and captures audiences everywhere, one question lingers: what makes this animation stand out from the rest? An answer lies in how relatable the main characters are.

The film follows three K-pop girl group members who use their music and voices to protect the world from demonic forces. While the storyline centres on the fantastical notion of “demon hunters”, grounding the protagonists in the guise of K-pop idols adds on-trend authenticity. As co-director Chris Appelhans explained, the aim was “making girls act like real girls, and not just pristine superheroes”.

Rather than dwelling solely on their heroics, the film portrays the characters’ everyday moments and ordinary behaviour. Food, clothes and familiar locations in South Korea are rendered with surprising precision, to the extent that even Korean audiences are astonished at their accuracy, despite the production being based overseas.

But how closely does the film’s version of K-pop reflect the real thing?

Take the first appearance of Huntr/x members Rumi, Mira and Zoey: with only minutes to go before a performance, they are shown devouring kimbap, ramen, fish cakes and snacks – fuel for the stage. In reality, idols may often end up grabbing a quick bite of kimbap or ramen in the car between packed schedules. More commonly, however, strict diets are the norm. There are reports that sometimes trainees – aspiring K-pop idols who are part of an entertainment company’s training programme – are even forced to shed weight by agencies: one of the industry’s darker aspects.

Yet, as idols mature, many develop their own healthier routines, not simply for looks but to ensure longevity in their careers.

Meanwhile, in the case of boy group Saja Boys, the film highlights the fans’ fascination with their sculpted abs. In reality, male idols often put themselves through intense workouts to build impressive physiques, showing off toned bodies and six-packs on stage for their fans.

Then there is the question of accommodation. In the film, Huntr/x members share a luxurious penthouse overlooking Seoul’s skyline. In reality, agencies often provide dorm accommodation to facilitate scheduling and teamwork, usually near the company, and often managers live with artists. The quality varies greatly, with newcomers typically placed in modest housing.

After debut, successful idols may upgrade their accommodation as the money starts to roll in, but a penthouse, as shown in the film, is more fantasy than fact. BTS being a notable exception, progressing from sharing a converted office (not even a proper house) to one of Seoul’s most prestigious apartments. Most idols tend to strike out on their own some years after debut, balancing solo activities with personal life. By then, their choice of home usually reflects their individual earnings.

The film mirrors K-pop reality in other respects. One Huntr/x member, Zoey, is Korean-American – reflecting the industry’s trend since the 2000s towards multinational line-ups designed to create a global audience. Blackpink, for instance, includes two Korean members with overseas backgrounds and one foreign national, which has bolstered their international reach.

The right music

The film also shows Zoey writing and composing songs: many idols are now singer-songwriters. With the industry demanding constant renewal, the shelf life of an “idol” is very short. Writing and producing music has become both a way to extend careers and secure additional income streams. BTS are all credited songwriters, while figures such as BigBang’s G-Dragon, Block B’s Zico, and i-dle’s Soyeon have all built reputations – and royalties – through their creative work.

Increasingly, even K-pop trainees now learn songwriting and production before their debut. Beyond these points, the film captures a wide slice of K-pop culture as it really exists – from fan sign events to the sea of light sticks waving at concerts.

More than any other element, it’s the music that gives the film its sharpest sense of realism.

Executive music producer Ian Eisendrath teamed up with record label THEBLACKLABEL to produce K-pop tracks that sound right at home in the current charts. Blending trendy and catchy hooks with the story itself has drawn in not only animation fans but also audiences lured by the music alone.

Co-director Maggie Kang put it plainly in an interview: “We really wanted to immerse the world in K-pop.” At the same time, she noted that the film deliberately heightens certain aspects of the genre. That kind of exaggeration is only natural in animation, where drama is part of the appeal. What matters is that every flourish is still grounded in reality.

For viewers familiar with Korean culture and K-pop, that means spotting a wealth of details that might otherwise go unnoticed – and it’s this layer of discovery that may well be among the key factors driving the popularity of KPop Demon Hunters.

How to help trigger positive tipping points – and speed up climate action

Source: The Conversation – UK – By Tim Lenton, Director, Global Systems Institute, University of Exeter

The rapid transition from horse-drawn carts to cars is an example of a positive tipping point. K.E.V/Shutterstock

The collapse of a major system of ocean currents, the meltdown of major ice sheets or the dieback of the Amazon rainforest are all examples of negative climate tipping points. These are the big risks associated with a changing climate, where harmful change becomes self-propelling. Each could cause environmental disasters affecting hundreds of millions of people.

The prospect of such irreversible and massively damaging outcomes is looming ever closer, as we are set to exceed 1.5°C global warming. Every year and every 0.1°C above this threshold increases the risk of crossing negative climate tipping points. To avert them, climate action must accelerate spectacularly. We need to decarbonise the global economy five times faster than the current rate to have reasonable odds of limiting warming well below 2°C.

This sounds both frightening and daunting. We are facing existential risks and to avoid them requires extraordinary rates and scales of social and technological change. It is understandable to feel climate despair or doomism – particularly with the current spate of backsliding on climate commitments.

But there are credible grounds for conditional optimism. They lie in the evidence of positive tipping points – where changes to zero-emission behaviour and technologies become self-propelling. This is now the only plausible way we can accelerate out of trouble, because we have left it way too late for incremental change to rescue us.

Tipping points happen when amplifying feedback within a system gets strong enough to support self-propelling change. Like putting the proverbial microphone too close to the speaker. They can happen in a range of systems, and history shows us they have happened repeatedly in social systems. Think of political revolutions, abrupt shifts in social norms – like the abandonment of smoking in public, or the rapid transition from horse-drawn carriages to cars.

Happily, almost everything that contributes to human-induced greenhouse gas emissions could be positively tipped towards zero emissions. It can take a lot of work to bring a system to a tipping point, but some key sectors have already positively tipped, at least in some countries.

Climate ‘tipping points’ can be positive too – our report sets out how to engineer a domino effect of rapid changes


Norway has tipped from buying petrol and diesel cars to EVs in the space of a decade. The UK abruptly shut down coal burning. While gas temporarily replaced some of coal’s role in electricity generation, rapidly growing renewable power has now replaced coal burning and is starting to displace gas. Neither transition happened by chance. Tipping our societies to zero emissions requires deliberate, intentional action from us all.

In Norway, change was started by social activists in the late 1980s, including members of the pop band A-ha, pushing the government to adopt a package of policies to incentivise EVs. In the UK, tipping was triggered by a rising floor price on carbon in the power sector, a policy that can be traced to the Climate Change Act, which started life as a private member’s bill, in turn born out of decades of environmental activism.

The beauty of tipping points

In my new book, Positive tipping points: How to fix the climate crisis, I highlight how just a small change can make a big difference. A minority can ultimately tip the majority. That minority activates amplifying feedback loops that get stronger with the more people who join in the change. This means we can all play a part in triggering positive tipping points.

We all make decisions about what we consume. Just by adopting a lower emission technology or behaviour (like eating less meat) we encourage others to join us. This is because people imitate one another, and the more people who adopt something the more people they can influence to adopt it too – a phenomenon known as “social contagion”.

With technologies, there are extra amplifiers of “increasing returns”: the more of us who adopt a new technology, the better it will get (through learning by doing), the cheaper it will get (due to economies of scale), and the more other technologies will emerge that make it more useful. This is how solar PV panels, wind turbines and batteries that power EVs have got ever cheaper, better and more accessible.

Policy usually also plays a crucial role in stimulating positive tipping points. Mandates to phase in clean technologies and phase out fossil fuelled ones are particularly effective. But despite polling evidence that roughly 80% of people worldwide support more decisive action on the climate crisis, governments can dither or be captured by vested interests. Sometimes they need to see what we support.

This may inspire us to get involved with social activism, which has its own tipping points. Each person joining a protest movement makes it incrementally easier for the next person to join. This can reach a critical mass – as it did for Fridays for Future and Extinction Rebellion in 2019. Or if, like me, you are not so comfortable on the march, there are other forms of social activism, like divesting from fossil fuels, or bringing civil cases against companies causing the climate crisis and governments failing to adequately respond to it.

Together a fraction of us can trigger positive tipping points to avoid otherwise devastating negative climate tipping points.

Mars has a solid inner core, resolving a longstanding planetary mystery — new study

Source: The Conversation – UK – By Kevin Olsen, UKSA Mars Science Fellow, Department of Physics, University of Oxford

NASA

Scientists have discovered that Mars has an interior structure similar to Earth’s. Results from Nasa’s Insight mission suggest that the red planet has a solid inner core surrounded by a liquid outer core, potentially resolving a longstanding mystery.

The findings, which are published in Nature, have important implications for our understanding of how Mars evolved. Billions of years ago, the planet may have had a thicker atmosphere that allowed liquid water to flow on the surface.

This thicker atmosphere may have been kept in place by a protective magnetic field, like the one Earth has. However, Mars lacks such a field today. Scientists have wondered whether the loss of this magnetic field led to the red planet losing its atmosphere to space over time and becoming the cold, dry desert it is today.

A key property of the Earth is that its core has a solid centre and liquid outer core. Convection within the liquid layer creates a dynamo, producing the magnetic field. The field deflects charged particles ejected by the Sun, preventing them from stripping the Earth’s atmosphere away over time and leading to the habitable conditions we know and enjoy.

From residual magnetisation in the crust, we think that Mars did once have a magnetic field, possibly from a core structure similar to that of Earth. However, scientists think that the core must have cooled and stopped moving at some point in its history.

On the surface of Mars there is a tremendous amount of evidence that liquid water once flowed, suggesting more hospitable conditions in the past. The evidence comes in many forms, including dry lake beds with minerals that formed under water, or the dramatic valley networks carved by rivers and streams. However, the Martian atmosphere is thin today and the necessary amount of water is nowhere to be found.

Teams working with the seismometers on Nasa’s InSight Mars lander first identified the Martian core and determined that it was actually still liquid. Now, the new results from Huixing Bi, at the University of Science and Technology of China in Hefei and colleagues, show that there may also be a solid layer inside the liquid core.

The nature of the interior structure of Mars has been an intriguing mystery. Was it ever like Earth’s, with a dynamic liquid layer around a solid centre? Or did Mars’ smaller size prevent such a formation? How big must a planet be to gain the protection of a magnetic field, like Earth’s, and support a habitable climate?

To understand what happened, how Mars evolved, we need to understand Mars today. These questions about Mars’ atmosphere, water, and core have motivated several high profile Mars missions. While the Nasa Mars rovers, Spirit, Opportunity, Curiosity, and Perseverance have studied the surface mineralogy, the European Space Agency’s ExoMars Trace Gas Orbiter is studying the water cycle, Nasa’s Maven spacecraft is studying atmospheric loss to space, and Nasa’s InSight lander was sent to study seismic activity.

Insight

In 2021, Simon Stähler, from ETH Zurich in Switzerland, and colleagues, published a seminal paper from the InSight mission. In it, they presented an analysis of the way that seismic waves pass through Mars from Mars quakes in the vicinity of InSight, through the mantle, through the core, and then reflecting off the other side of the planet and reaching InSight.

They detected evidence of the core for the first time and were able to constrain its size and density. They modelled a core with a single liquid layer that was both larger and less dense than expected and without a solid inner core. The size was huge, about half of Mars’ radius of 1,800 km, and the low density implied that it was full of lighter elements. The light elements, such as carbon, sulphur, and hydrogen, change the core’s melt temperature and affect how it could crystallise over time, making it more likely to remain liquid.

The solid inner core (610 km radius) found by Huxing Bi and colleagues is hugely significant. The very presence of a solid inner core shows that crystallisation and solidification is taking place as the planet cools over time.

The core structure is more like Earth’s and therefore more likely to have produced a dynamo at some point. On Earth, it is the thermal (heat) changes between the solid inner core, the liquid layer, and the mantle that drive convection in the liquid layer and create the dynamo that leads to a magnetic field. This result makes it more likely that a dynamo on Mars was possible in the past.

With Simon Stähler and co-authors reporting a fully liquid core and Huxing Bi and colleagues reporting a solid inner core, it might seem as if there will be some controversy. But that is not the case. This is an excellent example of progress in scientific data collection and analysis.

The findings will help guide scientists towards a better understanding of Mars’ evolution as a planet.

Competing models of Mars

InSight landed in November 2018 and its last contact with Earth occurred in December 2022. With Stähler publishing in 2021, there is some new data from InSight to look at. Stähler’s model was revised in 2023 by Henri Samuel, from the Université Paris Cité, and colleagues. A revised core size and density helped reconcile the InSight results with some other pieces of evidence.

In Stähler’s paper, a solid inner core is specifically not ruled out. The authors state that the signal strength of the analysed data was not strong enough to be used to identify seismic waves crossing an inner core boundary. This was an excellent first measurement of the core of Mars, but it left the question of additional layers and structure open.

For the latest study in Nature, the scientists achieved their result through a careful selection of specific seismic event types, at a certain distance from InSight. They also employ some novel data analysis techniques to get a weak signal out of the instrument noise.

This result is sure to have an impact within the community, and it will be very interesting to see whether additional re-analyses of the InSight data support or reject their model. A thorough discussion of the broader geological context and whether the model fits other available data that constrain the core size and density fit will also follow.

Understanding the interior structure of planets in our Solar System is critical to developing ideas about how they form, grow, and evolve. Prior to InSight, models for Mars that were similar to Earth were investigated, but were certainly not favoured.

How to help disabled and neurodivergent people flourish while working from home

Home-based working in the UK has been declining since the peak of the COVID pandemic – from 49% of the working population at its height to around 14% now.

While hybrid working is still increasing in popularity, attitudes persist among some employers that remote working reduces productivity, visibility and creativity. As a result, many workplaces are requiring a return to fully on-site working.

This approach, however, is not supported by research into hybrid working (a mix of working at home and on-site) which suggests productivity is not damaged and that it can also improve job satisfaction.

For many people who are disabled, neurodivergent or both, home-based working provides a real opportunity to gain – and retain – a job in a productive and supportive environment. Around 24% of the working-age population are disabled, with the employment rate among disabled people around 54%.

While disabled staff can request remote working as a reasonable adjustment, it can attract stigma. This is one reason why people may not always feel able to make this request, or say how much they would prefer to work from home. Some workers may fear repercussions like being overlooked for promotion or even losing their job.

I have studied the experiences of disabled and neurodivergent people who work from home, so I know how life-changing having a flexible job can be. One interviewee in my research told me: “I can sustain my productivity and, from my point of view, that means I can work better.”

Another said: “I don’t have to mask [attempt to hide autistic traits] at home. So there’s just a huge drop in … general anxiety and tension.”

Several large employers who took part in my study indicated that, while remote working was positive for many of their employees, there were downsides that needed to be managed. These include ensuring staff maintain their professional networks and social contacts, and discouraging working while unwell (presenteeism). Home working can intensify pressure to work while sick, and it may be harder to spot in a remote setting.

A toolkit for managers

Perhaps unsurprisingly, one of the key findings was that a supportive line manager was crucial for disabled and neurodivergent workers to make a success of remote working. Many managers, however, didn’t have enough knowledge or understanding of how to best to support each employee’s specific needs, so they couldn’t always offer appropriate guidance and advice.

With this in mind, I developed a toolkit for line managers to enable them to better support this community of workers. When good conversations happen between line managers and employees, solutions can be tailored to the person’s needs. The toolkit offers guidance to line managers on how to enable those conversations.

I make the case for remote working by setting out the benefits (including a more flexible workforce and more inclusive recruitment) for the organisation. The toolkit is designed to help managers recognise the ways in which home-based working can be positive for these workers, offering advice on how to reap the benefits while managing the downsides.

It also shares technical knowledge about disability and neurodivergence, such as how the UK Equality Act relates to this workforce, and how to approach the “reasonable adjustments” process (changes that an employer is legally obliged to make to ensure disabled staff are not at a disadvantage).

Managers these days often lead mixed teams of remote and on-site workers. To encourage effective remote working and productivity, my research has found that regular meetings and check-ins between line managers and home-working staff are important.

But sometimes it’s not enough for managers simply to level the playing field. People who are disabled, neurodivergent or both will benefit from tailored support in order to flourish in the workplace. They need to feel safe to disclose their conditions and needs, and to be themselves at work.

Remote working offers an opportunity to employ people who might not be able to work in a traditional office-based, “nine-to-five” environment. My research found that when key resources were in place, such as a conducive working environment, appropriate technology and a supportive line manager, this helped to build their self-confidence and autonomy.

It also helped them to manage their energy levels and self-care, which in turn supported better productivity, fewer absences and the ability to stay in work over the long term.

Employers should understand that the needs of this group of workers can unlock key strengths for their organisation – including diversity, staff retention and increased productivity. Remote working can present challenges for managers – but when managed well, it can also help them create a more flexible, inclusive and agile workplace.

The gospel according to Lady Gaga: why pop’s Mother Monster is also a theologian

Source: The Conversation – UK – By Stephen Roberts, Honorary Lecturer in Theology, Cardiff University

Lady Gaga is leading the nominations for this year’s MTV Video Music Awards – merely her latest accolade.

Since she burst onto the scene with The Fame album in 2008, Gaga has become one of the world’s most recognisable pop stars. Her hit Born This Way even topped Billboard’s list of the 100 greatest LGBTQIA+ anthems of all time. The track defines her commitment to celebrating diversity in all its forms.

While she is known for filling dance floors and dominating pop culture, she has also sparked serious academic interest. Scholars have explored her influence on music, fashion, gender and sexuality. Yet her use of religious imagery remains relatively under-examined. As a theologian, I have studied Gaga’s music and its rich religious symbolism.

Gaga’s most overtly political and theological album was Born This Way, released in 2011. It also inspired the Born This Way Foundation, which she founded with her mother to “empower and inspire young people to build a kinder, braver world that supports their mental health”.

I argue Gaga’s work makes her a kind of “musical public theologian”. In other words, an artist who brings theological arguments into public debate, particularly around LGBTQIA+ inclusion, often in tension with religious communities.

Born This Way

Take the title track. Here she tackles the theological opposition to LGBTQIA+ inclusion head on, in what might seem a fairly obvious and unsophisticated way: “No matter gay, straight, or bi, lesbian, transgender life, I’m on the right track, baby, I was born to survive … I’m beautiful in my way ’cause God makes no mistakes, I’m on the right track, baby, I was born this way.”

In a world where some claim that God’s design allows only for heterosexuality, Gaga turns this argument upside down. If God makes no mistakes, she insists, then diversity itself is divinely intended.

So far, so simple. But there is a more complicated story to be told about Gaga’s theological affirmation of difference. Some queer theorists are uneasy with the idea of being “born this way”, and the notion that identity is fixed by biology alone.

This is where deeper analysis of Born This Way pays dividends. The video offers a more fluid understanding of identity as something that can be performed.

Lady Gaga – Born This Way

It opens with a surreal sci-fi creation myth, scored with the theme from Alfred Hitchcock’s Vertigo (1958), a film in which identity is not straightforwardly “given”. The dancers adopt multiple postures resembling ovaries and wombs – a visual metaphor for the possibility of new births – suggestive of our ability to take on fresh identities for ourselves.

Gaga doesn’t do the work of connecting the lyrics and the visuals. That goes on in the world of queer theology, which is an approach that places LGBTQIA+ people at the centre of faith. But Gaga makes a significant public theological statement by holding them together in this song and its accompanying video.

Central to Gaga’s creative vision and resistance to dominant narratives telling people who and how they should be, is the theme of monstrosity. She calls herself “Mother Monster” and her fans “little monsters”, reclaiming a word often used to exclude or belittle those who are different.

The “Manifesto of Mother Monster”, at the beginning of the Born This Way video, presents a mythic creation story where freedom and difference are celebrated. It builds on the ambiguous place of monsters in religion.

Garden of Eden

Although her later albums are less overtly theological, Gaga has continued to weave religious themes into her music, including those of monstrosity. On her latest album Mayhem, for example, which was released earlier this year, the song Garden of Eden plays with the biblical story of the fall of Adam and Eve.

Lady Gaga – Garden Of Eden.

At one level, the theological motif of taking a bite from the apple in Eden can be seen simply as a metaphor for indulging in a short-lived relationship that, for that very reason, disobeys more conservative expectations of sexual relationships. But here, too, Gaga’s lyrics can be read at a deeper level. The story of Adam and Eve is fundamental to Christian theology, and it can be used to enforce certain ways of being.

Instead, Gaga’s reinterpretation of Eden offers a liberating vision. There’s an invitation to rethink a story that has been used to divide the world neatly into good and evil. Instead of using scripture to police behaviour, she reimagines it as a story that opens up possibilities. This reflects the experiences of many of her fans, who may have felt excluded by dominant religious narratives.

Through her music and imagery, Gaga invites us to embrace difference and to question stories that oppress. She queers tradition, offering an alternative theology rooted in inclusivity and creativity. Her work demonstrates that theology does not belong only in churches or seminaries. It can be found in music videos, stadium tours and dance anthems.

In studying Gaga’s work, I have come to see her as a theologian in her own right. She transforms pop music into a space where faith, identity and power are re-imagined. That, to me, is why she is worth celebrating, not just as a pop icon, but as someone who has turned theology into art for a wider audience.
