The brain needs time off, too. baranq/ Shutterstock

Every day, we’re faced with constant opportunities for stimulation. With 24/7 access to news feeds, emails and social media, many of us find ourselves scrolling endlessly, chasing our next hit of dopamine. But these habits are fuelling our stress – and our brains are begging for a break.

What our brains really need is some much needed time off from concentrating. By not consciously focusing on anything and allowing the mind to drift, this can reduce stress and improve cognitive sharpness.

This can often be easier said than done. But attention restoration theory (Art) can help you learn to give your brain space to drift. While this might sound like a fancy name for doing nothing, the theory is supported by neuroscience.

Attention restoration theory was first put forward by psychologists Rachel and Stephen Kaplan in 1989. They theorised that spending time in nature can help to restore focus and attention.

They proposed there are two distinct types of attention: directed attention and undirected attention. Directed attention refers to deliberate concentration – such as studying, navigating through a busy place or posting on social media. Basically, it’s any activity where our brain’s attention is being directed at a specific task.

Undirected attention is when we’re not consciously trying to focus on anything – instead allowing things to gently capture our attention without trying. Think listening to chirping birds or watching leaves gently rustling in the breeze. In these instances, your attention naturally drifts without having to force your focus.

Without time for undirected attention, it’s thought that we experience “attentional fatigue”. This can make it increasingly difficult to focus and concentrate, while distractions become more likely to grab our attention.

In the past, we encountered many situations in our daily lives that we might classify as “boring”. Moments such as waiting for the bus or standing in the supermarket queue. But these dull moments also gave our minds a chance to switch off.

Now, our smartphones give us the opportunity for constant entertainment. Being able to constantly expose ourselves to intense, gripping stimuli offers little mental space for our overworked brains to recover.

But attention restoration theory shows us how important it is to create space for moments that allow our brains to “reset”.

Restoring attention

The origins of Kaplan and Kaplan’s theory can actually be traced back to the 19th century. American psychologist William James was the first to formulate the concept of “voluntary attention” – attention that requires effort. James’ ideas were published against the backdrop of the broader cultural movement of Romanticism, which lauded nature.

Romantic ideas about the restorative power of nature have since been backed by research – with numerous studies showing links between time in nature and lower stress levels, better attention, improvements in mental health, mood and better cognitive function.

The restorative benefits of nature are backed by neuroscience, too. Neuroimaging has shown that activity in the amygdala – the part of the brain associated with stress and anxiety – was reduced when people were exposed to natural environments. But when exposed to urban environments, this activity was not reduced.

Numerous studies have also since backed up Kaplan and Kaplan’s theory that time in nature can help to restore attention and wellbeing. One systematic review of 42 studies found an association with exposure to natural environments and improvements in several aspects of cognitive performance – including attention.

A randomised controlled trial using neuroimaging of the brain found signs of lower stress levels in adults who took a 40-minute walk in a natural environment, compared to participants who walked in an urban environment. The authors concluded that the nature walk facilitated attention restoration.

Research has even shown that as little as ten minutes of undirected attention can result in a measurable uptick in performance on cognitive tests, as well as a reduction in attentional fatigue. Even simply walking on a treadmill while looking at a nature scene can produce this cognitive effect.

Time in nature

There are many ways you can put attention restoration theory to the test on your own. First, find any kind of green space – whether that’s your local park, a river you can sit beside or a forest trail you can hike along. Next, make sure you put your phone and any other distractions away.

Or, when you face boring moments during your day, instead of picking up your phone try seeing the pause as an opportunity to let your mind wander for a bit.

Each of us may find certain environments to be more naturally supportive in allowing us to switch off and disengage the mind. So if while trying to put attention restoration theory into practice you find your brain pulling you back to structured tasks (such as mentally planning your week), this may be sign you should go someplace where it’s easier for your mind to wander.

Whether you’re watching a ladybird crawl across your desk or visiting a vast expanse of nature, allow your attention to be undirected. It’s not laziness, it’s neurological maintenance.

What the world can learn from Korea’s 15th-century rain gauge

Droughts and floods are becoming more frequent and more severe across the globe. The cause is often rain — either too little or too much. The monsoon regions of the world, where societies have weathered cycles of drought and deluge for thousands of years, hold essential lessons about rainwater monitoring and conservation.

In Korea, one such lesson dates back to the 15th century. In 1441, during the reign of King Sejong, Korea established the world’s first official rain gauge (cheugugi) — a cylindrical copper instrument — and also created a state-administered rain monitoring network.

This wasn’t just a technical invention; it was part of a wider policy. On September 3 of that year, according to the Annals of the Choson Dynasty (a Unesco Memory of the World record), local magistrates across the country were ordered to measure rainfall regularly and report it to the central government.

This system represented one of the earliest forms of climate data governance and set a precedent for valuing rain as a measurable, manageable and fairly governed resource — a public good to be shared and respected. It also reflected a philosophical tradition in Korea of respecting rain not as a curse, but as a gift — one that must be understood, welcomed and shared.

India too has a rich tradition of rainwater harvesting, spanning from the Vedic period and the Indus–Sarasvati Valley civilisation (3,000–1,500BC) to the 19th century. Throughout diverse ecological zones, Indian communities developed decentralised systems to capture and store rainwater. The archaeological site of Dholavira in Gujarat, for example, featured sophisticated reservoirs designed to collect monsoon runoff.

Historical records, including ancient inscriptions, temple documents and folk traditions, indicate that these systems were not only engineered but also governed, with established rules for sharing, maintaining and investing in water as a communal resource. In some regions of India, every third house had its own well. Although these practices declined during colonial rule, they are now being revived by local communities, government initiatives, and non-governmental organisations.

The revival of traditional wells is gaining momentum, particularly in urban areas facing water scarcity. For example in the city of Bengaluru in southern India, local communities and organisations are using age-old well-digging techniques to tap into shallow aquifers. These efforts are often supported by the state or central government, as well as specialists and organisations including the Biome Environmental Trust, Aga Khan Trust for Culture, Indian National Trust for Art and Cultural Heritage, and the Centre for Science and Environment.

India’s current prime minister has also launched a campaign called Jal Shakti Abhiyan: Catch the Rain as part of a nationwide effort to restore and promote community-led rainwater harvesting.

Reviving ancient wisdom

In Korea, there’s also been a resurgence of this ancient wisdom in modern contexts. Although urban initiatives like the Star City rainwater management system show promise, the movement towards reviving old practices like rainwater harvesting is still growing.

Meanwhile in Cambodia, the Rain School Initiative empowers students and teachers to manage rainwater for drinking and climate education. Rainwater is not just a technical solution — it is a cultural key to resilience. It offers autonomy, sustainability and hope.

That is why we propose to establish UN Rain Day on September 3, in recognition of Korea’s historical contribution and in celebration of global rain literacy. It is a symbolic date that reminds us how rain has shaped civilisations and how it can shape our future — if only we choose to listen to the wisdom of water.

Designating international days has proven effective in raising awareness and catalysing global action. For instance, World Water Day (March 22) has spurred international cooperation and policymaking on water issues since its establishment in 1993. World Toilet Day (November 19) has elevated the global conversation around sanitation and public health.

A UN Rain Day would spotlight rain as a vital yet often overlooked resource. This is something that’s especially crucial for climate adaptation in monsoon regions and beyond.

What we’ve learned in ten years about county lines drug dealing

Source: The Conversation – UK – By Jenna Carr, Graduate Teaching Fellow and Sociology PhD Researcher, University of Liverpool

A decade ago, the National Crime Agency identified a new drug supply method. Before then, drug supply was predominantly between user-dealers – people supplying their social circles to fund their drug use, rather than for commercial gain.

In 2015, police outside of London identified a pattern of more frequent arrests of young people and vulnerable adults, implicated in drug supply outside of their local areas. They were also frequently suspected to be associated with members of criminal gangs. Thus, “county lines” was born.

The National Crime Agency used the term “county lines” to describe the phone or “deal” line used to organise the sale of drugs – mainly heroin and crack cocaine – from cities with oversaturated supplies, to rural, coastal areas with less supply.

The deal line was controlled by gang members based in the inner city area, such as London or Liverpool, known as “exporter” areas. The sale of drugs would be completed by a young or vulnerable person who had been exploited and sometimes trafficked out of their home areas to rural “importer” areas, such as north Wales and Cornwall. The crossing of local authority and police boundaries made county lines difficult to police, and to safeguard those who had been exploited.

County lines is notably violent. It involves gang violence, knife crime, drug misuse, sexual exploitation and modern-day slavery.

Ten years on, county lines as a supply model continues to evolve. A recent assessment by the National Police Chiefs’ Council found that the practice is becoming more localised, with fewer lines running between police force boundaries, and more running from one end of a force to the other end. It is also no longer limited to the supply of class A substances, with police reporting seizures of cannabis, cash and weapons.

Researchers are now suggesting that the term “county lines” itself is outdated, and instead should be replaced with a term that focuses more on the exploitation involved, rather than drug supply.

Who gets involved

County lines affects both children and vulnerable adults. The government has estimated 14,500 children to be at risk of child criminal exploitation, but this is likely to be an underestimation. Particular risk factors include being between 15 and 17 years old, experiences of neglect and abuse, economic vulnerability, school exclusion and frequent episodes of missing from home.

Cuckooing, where a gang will take over homes as a base for drug supply, largely affects vulnerable adults, rather than children.

One challenge in responding to county lines is that vulnerability can be difficult to recognise.
Victims and perpetrators of exploitation are often one and the same. Often, victims will be unwilling to cooperate with police, out of fear of legal consequences and repercussions from their exploiters.

Those who have been exploited into participating in county lines often do not accept that they are a victim – they may think they are profiting from their involvement, both financially and socially. The ongoing cost of living crisis draws young and vulnerable people into county lines as a response to poverty and lack of legitimate and financially viable opportunities.

Responding to county lines

My ongoing research looks at the development of county lines policy and responses to the problem over the last ten years. Responses to county lines have been mainly led by law enforcement, with coordinated police “crackdowns”. But research shows that high-profile police operations are largely symbolic, and have the effect of drawing vulnerable people into the criminal justice system, which creates further harm.

One important development has been the use of the Modern Slavery Act to prosecute county lines. The purpose of this is to offer a legal defence for someone who has been exploited into selling drugs. But research has shown, rather than acting as a safeguard and a defence, it acts as a “gateway into criminalisation”.

If someone crosses the boundary of being a victim to becoming a perpetrator of exploitation, they can also find themselves being subjected to punitive criminal justice responses under the Modern Slavery Act. This is especially true for black men and boys, who have historically been treated more harshly, for example through stop and search, in relation to drug crime.

It’s become clear that county lines is an issue that criminal justice alone cannot respond to. Those who are at risk require safeguarding, not criminalisation. To this end, the government funds a specialist county lines victim support service that operates in the four main exporter locations.

But the availability of this support service only in exporter locations shows that the county lines response is a postcode lottery. Police forces in importer areas have fewer resources to dedicate to training officers to deal with complex county lines cases. A consistent national approach is still required.

What’s next?

The current government is planning to make child criminal exploitation and cuckooing specific criminal offences through new legislation. This has been celebrated as a success by child safety charities.

But should more criminalisation be the priority? Research shows that drug prohibition and punitive responses are ineffective at preventing young people and vulnerable adults becoming involved in county lines. The demand for drugs and structural issues such as poverty are fuelling county lines – policing alone cannot address this.

Instead of punitive legal responses, public health and addressing the demand for drugs should be priority. Investment is needed in support services and social care, which have been decimated by austerity cuts, to build a society where vulnerable people do not need to become involved in drug supply.

Will the new James Bond embrace hi-tech gadgets in an age of AI? The films have a complicated history with technology

Source: The Conversation – UK – By Christopher Holliday, Senior Lecturer in Liberal Arts and Visual Cultures Education, Department of Interdisciplinary Humanities, King’s College London

Development of a new James Bond film is underway at Amazon Studios, with the creater of Peaky Blinders, Steven Knight, now attached to write the screenplay, which will be directed by Denis Villeneuve.

The pair have given little away about what to expect from Bond 26. Knight said he wanted to do something “the same but different”, while Villeneuve said he would “honour the tradition” of the franchise. But a look back at how the films have dealt with key elements of Bond shows that following tradition can mean going in many different ways.

Take Bond’s toolbag of gadgets, which have been a part of the James Bond movies since their debut in the 1960s. Over the decades, the films have both leaned into and shifted away from the allure of hi-tech gadgetry in ways that plot key turning points in the franchise.

These peaks and troughs reflect what’s going on in the wider world as well as factors such as the influence of other successful film franchises. So with AI on the minds of many right now, the new film could embrace contemporary themes of technology. But re-booting the franchise when a new lead actor is cast is also often associated with a grittier or “back to basics” approach.

The first few Bond films starring Sean Connery, including Dr No (1962), From Russia With Love, and Goldfinger (1964) feature a smattering of spy technology. But by You Only Live Twice (1967), producers had opted for a space capsule hijack narrative – reflecting the influence of the US-Soviet space race – and a villain’s lair in a hollowed-out volcano.

However, the next entry – On Her Majesty’s Secret Service (1969) centred largely on the emotional realism of Bond’s (George Lazenby) courtship and subsequent marriage to Tracy di Vicenzo (Diana Rigg). The lesser focus on technology coincided with a new Bond actor – a pattern to be frequently repeated later on in the franchise. But for other reasons, the shift in tone was, perhaps, to be expected.

Goldfinger: Q introduces Bond to his Aston Martin.

Bond author Ian Fleming was writing On Her Majesty’s Secret Service at his holiday home – Goldeneye – in Jamaica, while Dr No was being filmed nearby. The book was published on April 1, 1963, the day From Russia With Love began filming (the film was released in October that year). The less gadget-focused approach of On Her Majesty’s Secret Service could be seen as a possible jab by Fleming at what he saw as the cinematic Bond’s growing overreliance on the latest tech.

Journeying back through the franchise, it is not hard to find instances where moments of technological excess are countered almost immediately by a more pared down, character-centred set of priorities.

After On Her Majesty’s Secret Service, Connery returned for one further Eon Productions film, Diamonds Are Forever (1971), which, like You Only Live Twice, featured a space-themed narrative. Live And Let Die (1973), Roger Moore’s debut as Bond, is somewhat more down to Earth and was the first film not to feature Bond’s gadgetmaster Q (who is referred to as Major Boothroyd in Dr No).

But a growing reliance on technology can be seen during the 70s Moore films, culminating with Moonraker (1979) – which was heavily influenced by Star Wars (1977) – in which Bond goes into space.

Moore’s follow-up, For Your Eyes Only (1981), was – as that film’s director John Glen noted – a film that went “back to the grass roots of Bond.” The global economic recession that took place between 1980 and 1982 certainly helped support this shift in tone.

For Your Eyes Only had a lower budget than Moonraker, so the filmmakers had to act in a similar way to their leading character, who made innovative use in the film of his shoelaces to climb up a rope on a sheer rock face in Greece.

The last few Roger Moore films have examples of Bond’s complex connection to technology, such as the computer microchip narrative of Moore’s final film A View to a Kill. But the next film, The Living Daylights (1987), was a return to the grittier Bond of the novels – with a focus on classic spycraft. From an action-packed opening in Gibraltar, the narrative moves to Bratislava where Dalton helps a KGB General defect to the west.

When Dalton departed after Licence to Kill (1989), which shows the influence of big-budget 80s Hollywood action movies, the series’ return after a six-year hiatus brought Bond into the information age. The cyberterrorist narrative of GoldenEye (1995), Pierce Brosnan’s debut as Bond, is fully indebted to a broader curiosity surrounding emerging internet sub-cultures.

Brosnan’s final outing, Die Another Day (2002) featured an Aston Martin that could turn invisible, which critics and audiences dismissed as a series nadir. The post-9/11 climate of protector narratives in defence of national security featured an altogether grittier action cinema counting Jason Bourne as its most popular hero. Die Another Day’s invisible Aston Martin and the indelible image of a computer-generated Bond surfing amid digital icebergs did not quite align with this state of post-millennial geopolitics.

Enter Daniel Craig, and the franchise’s emphatic declaration that it was going to do things for real, per the title of a documentary on Craig’s debut Casino Royale (2006). This was a statement of intent, anchored not just to a reduction in computer-generated imagery (CGI) behind-the-scenes, but equally by a turn away from the kinds of excessive technological wizardry that defined earlier instalments.

The absence of Q from Craig’s debut Casino Royale (2006) for the first time since Live and Let Die appeared to confirm a more “back to basics” feel. When the character did finally appear in Craig’s third film Skyfall (2012), Q (now played by Ben Whishaw) remarks to Bond: “Were you expecting an exploding pen? We don’t really go in for that anymore.”

Die Another Day trailer.

With another reboot on the way, the question now is whether the new film will draw inspiration from real-world technologies and push once more at the limits of technical innovation. Perhaps Villeneuve will exploit his science-fiction credentials finetuned in Arrival (2016), Blade Runner 2049 (2017) and his successful Dune films (2021-2024).

But given how contemporary cultural landscape is awash with the threat of AI, maybe the franchise does need to beat a hasty retreat from technology in order to stand out. Either way the filmakers will be able to argue they are sticking to tradition.

Agents masqués et armés : la police migratoire de Trump sème la peur dans les rues américaines

Source: The Conversation – France in French (3) – By Dafydd Townley, Teaching Fellow in US politics and international security, University of Portsmouth

Aux États-Unis, la police de l’immigration de Donald Trump multiplient les raids ciblant les personnes non blanches, principalement sans papiers ou titulaires d’un titre de séjour. Bras armé de la politique migratoire de Donald Trump, cette agence fédérale (ICE), renforcée par un budget historique, applique une répression de grande ampleur.


Des hommes masqués, et parfois des femmes, patrouillent dans les rues des villes américaines, parfois à bord de voitures banalisées, souvent armés et vêtus de tenues militaires. Ils ont le pouvoir d’identifier, d’arrêter, de détenir des personnes qui n’ont pas la citoyenneté américaine et d’expulser les immigrés sans papiers. Ils ont également le droit d’interroger toute personne qu’ils soupçonnent de ne pas être citoyenne américaine afin de vérifier son droit de séjourner aux États-Unis.

Ce sont des agents de l’Immigration and Customs Enforcement Agency, connue sous le nom d’Ice. Il s’agit d’un organisme fédéral chargé de l’application de la loi, qui relève du département de la Sécurité intérieure (DHS) et qui joue un rôle important et controversé dans la mise en œuvre de la politique d’immigration stricte de Donald Trump.

Lors de la campagne électorale, Trump a promis « la plus grande opération d’expulsion intérieure de l’histoire américaine ». Et il donne à Ice plus de pouvoir pour réaliser ses projets.

Depuis l’entrée en fonction de Trump en janvier, le financement d’Ice a été considérablement augmenté. Le « big beautiful bill » (« grand et beau projet de loi ») de Trump, adopté par le Congrès en juillet 2025, a accordé à Ice 75 milliards de dollars US (65 milliards d’euros) pour les quatre années à venir, contre environ 8 milliards de dollars US (6,9 milliards d’euros) par an auparavant.

Cette augmentation de financement permettra à l’agence de recruter davantage d’agents, d’ajouter des milliers de lits supplémentaires et des extensions aux bâtiments afin d’augmenter la capacité des centres de détention. De nouveaux fonds sont également prévus pour des outils de surveillance avancés, incluant la reconnaissance faciale assistée par IA et la collecte de données mobiles. Une enveloppe supplémentaire de 30 milliards de dollars (26 milliards d’euros) est destinée aux opérations de première ligne, notamment l’expulsion des immigrants et leur transfert vers les centres de détention.

Le président s’est engagé à expulser toutes les personnes en situation irrégulière aux États-Unis, soit, selon le Wall Street Journal, environ 4 % de la population actuelle. Au cours des cinq derniers mois, le nombre de personnes interpellées par les agents d’Ice a augmenté rapidement.

Le nombre moyen d’arrestations quotidiennes a augmenté de 268 %, atteignant environ 1 000 par jour en juin 2025, comparé au même mois un an plus tôt. Cela représente également une hausse de 42 % par rapport à mai 2025, selon une analyse des données réalisée par le Guardian et le Deportation Data Project. Cependant, ce chiffre reste bien en deçà des 3 000 arrestations par jour ordonnées par la secrétaire à la Sécurité intérieure Kristi Noem et le chef adjoint de cabinet de la Maison Blanche Stephen Miller.

Les tactiques d’Ice ont déjà suscité de vives critiques. La chaîne de télévision conservatrice Fox News a rapporté que des agents masqués ne présentaient pas leur carte d’identité ni le nom de leur agence lorsqu’ils interpellaient des personnes lors de raids. D’autres reportages ont mis en lumière des allégations selon lesquelles des citoyens américains seraient également parfois pris dans ces raids.

Fonctionnement et organisation d’ICE

L’agence, actuellement dirigée par le directeur par intérim Todd M. Lyons, comporte trois divisions principales :

Lyons a affirmé que le port du masque était nécessaire car les agents de l’ICE étaient victimes de « doxxing », c’est-à-dire que leurs informations personnelles, telles que leurs noms et adresses, étaient divulguées en ligne sans leur consentement. Il a également déclaré que les agressions contre les agents d’Ice avaient augmenté. Les données du DHS indiquent qu’il y avait eu 79 agressions contre des agents d’Ice entre janvier et juin 2025, contre dix sur la même période en 2024.

Le chef de la minorité démocrate à la Chambre des représentants, Hakeem Jeffries, a comparé le port du masque par les agents d’Ice à des forces de police secrète dans des régimes autoritaires : « Nous ne sommes pas derrière le Rideau de fer. Nous ne sommes pas dans les années 1930. »

L’agence Ice a été créée en 2003 par l’administration de George W. Bush, en partie à la suite des attentats terroristes du 11 septembre, et faisait partie d’une réorganisation plus large des agences fédérales sous la direction du DHS alors tout juste créé. Elle a intégré des parties de l’ancienne Immigration and Naturalization Service (INS) ainsi que certains éléments du Service des douanes américaines.

Selon le site web de l’agence, la mission principale d’Ice est « de protéger l’Amérique par le biais d’enquêtes criminelles et de l’application des lois sur l’immigration afin de préserver la sécurité nationale et la sécurité publique ».

Comment ICE a accru ses moyens et son champ d’action

Au début du mandat présidentiel en janvier dernier, la Maison Blanche a donné à Ice le droit d’accélérer l’expulsion des immigrés entrés légalement dans le pays sous l’administration précédente. Ce « droit d’expulsion accélérée » permettait à Ice d’expulser des personnes sans qu’elles aient à comparaître devant un juge de l’immigration.

Alors que les arrestations se sont multipliées ces derniers mois, Lyons a déclaré à CBS News qu’Ice traquait tout immigrant sans papiers, même s’il n’avait pas de casier judiciaire.

L’administration Trump a également autorisé les agents de l’ICE à procéder à des arrestations dans les tribunaux d’immigration, ce qui était auparavant interdit. Cette restriction avait été introduite par l’administration Biden en 2021 afin de garantir que les témoins, les victimes de crimes et les accusés puissent toujours comparaître devant la justice sans craindre d’être arrêtés pour des infractions à la législation sur l’immigration (à l’exception des personnes représentant une menace pour la sécurité nationale).

La plupart du temps, Ice a ciblé les immigrants illégaux. Mais l’agence a aussi arrêté et détenu certaines personnes qui étaient résidentes (détentrices de la carte verte) ou touristes – et, dans certains cas même des citoyens étatsuniens.

Ces dernières semaines, selon le Washington Post, ICE a reçu l’ordre d’augmenter le nombre d’immigrants équipés de bracelets électroniques GPS. Cela augmenterait considérablement le nombre d’immigrants sous surveillance. Ces dispositifs limitent également la liberté de mouvement des personnes concernées.

Des manifestations face aux raids d’ICE

De nombreuses manifestations publiques ont eu lieu contre les raids d’Ice, notamment en Californie. Le point culminant a été atteint le 6 juin après qu’Ice ait mené plusieurs raids à Los Angeles, qui ont donné lieu à des affrontements entre agents et manifestants. Cela a conduit la Maison Blanche à envoyer environ 2 000 soldats de la Garde nationale et 700 Marines à Los Angeles, malgré l’opposition du gouverneur de Californie, Gavin Newsom.

Trump face à la Californie : affrontement à haute tension


Une partie des tensions entre l’administration Trump et l’État vient du fait que Los Angeles et San Francisco ont adopté des politiques locales limitant la coopération avec les autorités fédérales en matière d’immigration, notamment ICE. La Californie dispose de lois sur les sanctuaires, telles que la SB 54, qui interdisent aux forces de police et aux shérifs locaux d’aider Ice dans l’application des lois civiles sur l’immigration.

Cependant, Trump semble déterminé à durcir et accélérer la répression contre les immigrants illégaux, et les agents d’Ice sont clairement en première ligne de cette stratégie.

Storm Floris: the weather is rarely this windy in August – which makes it more dangerous

Source: The Conversation – UK – By Colin Manning, Postdoctoral Research Associate in Climate Science, Newcastle University

Storm Floris made landfall in northern parts of the UK on the morning of Monday August 4 2025, bringing intense rainfall followed by severe winds throughout the afternoon. The Met Office issued an amber weather warning for much of Scotland and yellow alerts for parts of Northern Ireland and northern England.

Affected areas can expect 20mm–40mm of rain on average, with some areas of Scotland potentially receiving up to 80mm. Wind speeds in exposed and elevated regions could reach 80mph–90mph, while gusts of 50mph-60mph are forecast for much of Scotland.

The storm’s defining characteristic is the unusually strong winds for August, a time typically less prone to severe wind events. The odd seasonal timing has increased the risk to the public, as more people are outdoors, travelling for holidays or staying in campsites. In addition, trees remain in full leaf, making them more likely to be brought down by high winds.

Authorities are anticipating significant disruption to transport and electricity networks largely due to falling trees. This is underlined by recent research showing an increased risk of large power outages during windstorms that occur in summer. A large amount of debris on the ground from trees may also block drainage systems and contribute to localised flooding.

Persistent strong winds will combine with periods of heavy rainfall for the duration of the amber alert, which expires at 23:00. This will create difficult conditions for emergency workers and prevent access to affected locations if roads are blocked, potentially prolonging disruptions to travel and power networks.

Is this typical of summer months?

Storm Floris carries all the hallmarks of a classic mid-latitude storm. These develop due to sharp temperature contrasts between the northern and southern Atlantic Ocean and intensify under the influence of a strong jet stream. This is a core of fast-moving air high in the atmosphere that stretches across the Atlantic and often steers storms towards the UK.

Such conditions are unusual for the summer months, when warmer Atlantic sea temperatures typically weaken these temperature gradients and shift them farther north, closer to the polar regions. However, it is not uncommon for such storms to occur in August.

Notable ones in the past five years include Storm Ellen, which extensively damaged electricity distribution infrastructure in Ireland and led the Irish meterological service to produce and red and amber weather warning for southern parts of Ireland. Previous storms in August cancelled the Boardmasters music festival in Cornwall in 2019 and closed two stages of Leeds festival in 2024.

Floris is classified as a Shapiro-Keyser cyclone, a type distinguished by a warm core encircled by colder air on its north, west and south sides. This structure is visible in the way the storm’s frontal system wraps around its centre, forming a characteristic comma-shape in the clouds around the cyclone centre. Storms of this kind are responsible for a significant number of the UK’s most damaging wind events.

These cyclones often feature sharp pressure gradients and strong low-level airflows, particularly an air stream known as the cold jet, or cold conveyor belt, which can produce severe surface winds. In some cases, they can also generate a sting jet, a narrow stream of air that descends rapidly from around 5km above the land surface, delivering intense, damaging gusts.

Fortunately, satellite imagery suggests that Storm Floris is unlikely to have produced a sting jet. However, the cold jet alone may still drive wind speeds high enough to cause widespread disruption.

These types of storms can also produce intense rainfall along their frontal boundaries, as seen with Storm Floris. Warmer summer temperatures allow the atmosphere to hold more moisture, increasing the potential for heavier downpours. In addition, the heat contributes to a more unstable atmosphere, encouraging strong convective ascents of air that can yield extremely heavy and localised rainfall.

Floris in the future

Research shows that climate change will influence the characteristics of storms like Floris, though not all aspects will be affected equally. Warmer temperatures are expected to make future storms wetter, as increased atmospheric moisture and convective activity enhances rainfall, particularly along frontal systems. However, projections of wind extremes remain more uncertain.

Climate models generally suggest a modest intensification of winter storms over the UK and a decrease in the intensity of summer storms, implying that systems like Floris could become less common. These projections are largely tied to expected changes in Atlantic temperature gradients and the behaviour of the jet stream.

That said, most long-term climate projections rely on relatively coarse-resolution models which often fail to capture key features that drive storm intensification. These include the gulf stream (a warm Atlantic Ocean current) and drivers of extreme winds including the cold jet and sting jet.

A higher-resolution model, like that used in real-time forecasting for Storm Floris, predicts more intense winter windstorms in a warmer climate. Much of this intensification is linked to stronger cold jets and a potential increase in storms that generate sting jets.

Many powerful summer and autumn storms in the UK originate from tropical cyclones such as hurricanes, as seen with Storm Ophelia in 2017. These systems are poorly represented in lower-resolution climate models, yet they contribute significantly to Europe’s most extreme windstorms.

While Storm Floris has no tropical origins, a variety of storms can affect northern Europe at this time of year. The complexity of assessing their risks remains an area of ongoing research.

Boîtes de conserve : des risques invisibles pour la santé ?

Mieux vaut éviter d’assaisonner des pâtes ou des salades avec le liquide contenu dans les boîtes de conserve, car cela pourrait augmenter l’exposition à certaines substances à risque. Ilia Nesolenyi/Shutterstock

Les boîtes de conserve métalliques qui contiennent des aliments ou des boissons sont des emballages sûrs pour la santé. Cependant, il est nécessaire d’approfondir les interactions possibles entre l’emballage et les aliments. C’est ce qui ressort d’analyses faites sur du thon et des boissons en conserves par des chercheurs de l’Université de Santiago de Compostela, en Espagne, en collaboration avec l’Agence nationale de sécurité alimentaire et nutrition (AESAN).


Elles font partie de tout kit de survie et beaucoup d’entre elles sont indispensables à la vie universitaire des étudiants. Si nous n’avons pas envie de cuisiner ou quand nous manquons de temps, elles sont la meilleure option, et elles sont indispensables si nous partons camper. Nous parlons bien sûr des conserves qui permettent de garder différents types d’aliments et de boissons dans des conditions nutritionnelles et organoleptiques parfaites.

Ce mode de conservation est utilisé depuis des décennies dans notre système alimentaire. Parmi ses nombreux avantages, il permet notamment de garder les aliments dans nos placards pendant des années grâce à leur date limite de consommation très longue.

De ce fait, traditionnellement, dans la société, les boîtes de conserve sont associées à un moyen sûr de conserver les aliments. Cependant, d’un point de vue chimique, il est nécessaire d’étudier plus en profondeur les interactions possibles entre l’emballage et les aliments qu’il contient afin de garantir leur innocuité.

En général, sauf si nous constations des bosses ou des traces de rouille sur les conserves, nous considérions que nous pouvions être tranquilles. Un choc nous mettait en alerte et ce, à juste titre, car cela peut endommager l’intégrité de la boîte au point de provoquer de petites perforations qui ne sont pas toujours visibles, ce qui facilite l’entrée de bactéries et, par conséquent, la contamination des aliments à l’intérieur de la conserve.

Ce qui a généralement été ignoré ou, a minima, insuffisamment abordé, ce sont les questions de sécurité alimentaire liées aux composants de la boîte de conserve, par exemple l’augmentation potentielle de l’exposition à des substances dangereuses que représenterait l’assaisonnement d’une salade avec l’huile qui accompagne le thon en conserve.

Les risques liés aux composants des boîtes de conserve

De quelles substances parlons-nous ? Et surtout, à quels risques sommes-nous exposés ? Les emballages métalliques contiennent généralement des revêtements polymères qui agissent comme une barrière entre les aliments et le métal. Ce revêtement empêche la corrosion de la boîte et préserve les propriétés organoleptiques et la qualité des aliments.

Cependant, certains de ses composants peuvent se retrouver dans les aliments par un processus appelé migration. Cela peut affecter la qualité du produit et, dans certains cas, représenter un risque potentiel pour la santé du consommateur, soit en raison de son ingestion en quantités importantes, soit en raison d’une exposition cumulée tout au long de la vie via l’alimentation.

Des perturbateurs endocriniens dans les boîtes de conserve

Le groupe FoodChemPack (Recherche, développement et évaluation de la sécurité chimique des aliments et des matériaux en contact avec les aliments) de la faculté de pharmacie de l’université de Santiago de Compostela (USC), en Espagne, étudie les revêtements des boîtes métalliques, pour les boissons comme pour les conserves alimentaires, dans le cadre de plusieurs projets (MIGRAEXPO, MIGRACOATING, BACFood4Expo et ACHED), en collaboration avec l’Agence espagnole dédiée à la sécurité alimentaire et à la nutrition (AESAN).

Au cours de ces dernières années, nous avons constaté que de nombreux revêtements contenaient des résines époxy à base de bisphénol A diglycidyl éther (BADGE), synthétisé à partir d’épichlorhydrine et de bisphénol A (BPA), un perturbateur endocrinien qui interfère avec le système hormonal. Il contribue ainsi au développement de maladies métaboliques, telles que le diabète ou l’obésité, et peut affecter le système reproducteur, entre autres effets néfastes. En 2011, la dangerosité de ce composé a ainsi conduit à son interdiction dans les biberons pour bébé.

Les autorités européennes réduisent de plus en plus la quantité maximale de bisphénol à laquelle la population générale devrait être exposée. À tel point que la Commission européenne a récemment interdit l’utilisation du BPA et de ses dérivés dans les matériaux destinés à entrer en contact avec des denrées alimentaires.

Le thon, plutôt au naturel que dans l’huile ou à l’escabèche

Dans les boissons que nous avons étudiées (boissons alcoolisées, énergisantes, rafraîchissantes ou eau minérale), la migration de ces composés dérivés du bisphénol A s’est avérée faible. En revanche, dans les aliments en conserve, en particulier dans ceux à forte teneur en matières grasses, des niveaux de migration plus élevés ont été mesurés.

Par exemple, dans les conserves, comme le thon à la tomate, à l’escabèche ou à l’huile, des concentrations plus élevées que dans le thon au naturel ont été relevées pour un autre composé appelé cyclo-di-BADGE. Contrairement au BPA, ce composé n’est pas encore réglementé en raison du manque d’informations toxicologiques.

Pour toutes ces raisons, nous considérons que ce n’est pas une bonne habitude d’assaisonner des pâtes ou des salades avec le liquide contenu dans les boîtes de conserve, car cela pourrait augmenter notre exposition à ces substances.

De plus, il a été observé que le fait de réchauffer les aliments directement dans la boîte de conserve, une pratique associée à des contextes spécifiques, tels que le camping, peut augmenter la migration de ces composés. En effet, la chaleur accélère les processus de transfert des substances depuis la couche interne de l’emballage vers les aliments, ce qui pourrait augmenter les risques pour la santé.

Qu’absorbons-nous, comment et en quelle quantité ?

Dans des études récentes, nous avons constaté que la bioaccessibilité de ces substances, c’est-à-dire la quantité qui pourrait être absorbée par l’organisme, augmente considérablement lorsqu’elles sont ingérées avec des aliments gras.

Pour parvenir à cette conclusion, nous avons tenté de simuler la manière dont notre système digestif traite ces composés. Pour ce faire, nous avons utilisé le protocole de digestion gastro-intestinale in vitro INFOGEST qui, entre autres, simule la composition de la salive et des fluides gastro-intestinaux, la durée de chaque phase, la température ou les valeurs de pH corporelles. Nous avons ainsi pu observer comment différents groupes de populations sont exposés de manière différente à ces substances, principalement en fonction du pH basal de l’estomac, qui est de 1,5 chez les adultes, tandis que les enfants et les personnes âgées ont un pH gastrique moins acide.

Dans la majorité des cas, les quantités détectées étaient inférieures aux limites fixées par la Commission européenne. Il est toutefois important de tenir compte de l’exposition potentielle par différentes voies et de l’exposition cumulative tout au long de la vie. En effet, une personne peut être en contact avec la même substance de différentes manières, non seulement par voie orale, par l’eau ou les aliments, mais aussi par d’autres voies, telles que les voies respiratoires ou cutanées. Cela peut augmenter l’exposition totale de l’organisme à cette substance.

Même à de faibles niveaux, une exposition prolongée peut avoir des effets négatifs sur la santé, en particulier chez les groupes de populations les plus vulnérables.

Une société informée, une alimentation plus sûre

La connaissance de ces résultats, et de ceux à venir, permettra aux consommateurs de prendre des décisions éclairées concernant l’utilisation de ce type d’emballages (par exemple, ne pas chauffer directement les boîtes de conserve sur le feu lorsque l’on fait du camping) et la consommation des aliments (par exemple, éviter de réutiliser les liquides de couverture pour assaisonner les salades), ce qui contribuera ainsi à une alimentation plus sûre.

Pets don’t necessarily improve their owners’ well-being

Source: The Conversation – Canada – By Christophe Gagné, PhD candidate, Psychology, Université du Québec à Montréal (UQAM)

People often turn to pets to boost their mood and find companionship. Improving well-being and reducing loneliness are among the most cited reasons for adopting an animal companion.

But even though the belief that pets bring many benefits to their owners is widespread, research shows that having a pet is not a panacea for bolstering human psychological well-being.

Despite this, pets are often portrayed in the news and on social media as effective solutions to reduce stress and loneliness, reflecting a popular belief in their health benefits. This can lead people to adopt pets without fully considering the responsibilities and demands involved, which can have negative consequences for both themselves and their pets.

As social psychologists studying human-pet relationships, we take a more nuanced approach, examining when, how and for whom pets can — or cannot — enhance well-being.

What the research says

Many studies have found that pet owners are less anxious, lonely and stressed out compared to people who don’t have pets. Pet owners also report being more satisfied with their life.

These studies often catch our attention because they tap into something many of us believe: that our pets are good for us. This type of research offers reassurance and validates the deep bond we may feel with our animal companions. But they only tell one side of the story.

Other studies have found no significant link between pet ownership and human well-being. In other words, people with pets don’t necessarily report higher well-being, nor do they have better mental health than those without pets.

Dogs may reflect their owners’ stress levels, finds research


Our research into pet ownership in Canada during the COVID-19 pandemic was surprising: it found that owning a pet was generally associated with lower well-being and mental health.

The study included both pet owners and those without pets, aiming to compare the two groups on various well-being indicators during the pandemic. Pet owners reported lower well-being than non-pet owners during that time, including higher levels of loneliness.

These inconsistencies across different studies show that the connection between having a pet and feeling good isn’t so straightforward. Our study indicated some of these complexities. For example, compared to owners of other pets, dog owners reported higher well-being.

To make sense of these mixed findings, researchers have started to look more closely at the nature of the relationship between owners and their pets. This approach may help us better understand the factors that influence whether pet ownership is beneficial for our well-being.

The quality of the connection

Just like our relationships with people, our bond with pets is complex. Many aspects of this connection can influence how much we benefit from it. It’s not just having a pet that counts, but how we bond and interact with them.

For example, owners who experience anxiety about being away from their pets or question their pet’s affection — reflecting an insecure attachment to a pet — also report feeling more depressed. Perceiving our pets as less understanding or more insensitive to our needs is also associated with higher levels of depression, anxiety and loneliness.

In contrast, the more people feel that they share characteristics with their pets (for example, loyalty, a mutual love of sleeping), the more likely they are to report higher well-being. Pets are also perceived as living in the present, not dwelling on the past or worrying about the future. Interacting with our animal companions mindfully can help us focus on the present moment as well, which also promotes greater well-being.

Do people really resemble their dogs?


By nurturing the positive aspects of our relationships with pets and working through the more difficult ones, we may ease the stress associated with some of the challenges of caring for them, including the financial resources required or the anxiety we feel when they get sick.

Some challenges of pet ownership

In fact, pet ownership comes with responsibilities and challenges that don’t seem to be discussed as often as the benefits. These more difficult aspects of caring for a pet can sometimes be emotionally distressing and negatively impact a pet owner’s psychological well-being.

Having pets, no matter how much we love them, requires time, energy and financial resources. For some, especially during the COVID-19 pandemic, this responsibility may represent an additional source of stress. In our study, pet ownership was linked to lower well-being among women and among those with two or more children at home — groups already facing increased child-care and household demands.

Similarly, pet ownership was associated with lower well-being for people who were unemployed or in less stable forms of employment (for example, students, homemakers). Limited financial resources may have made pet care more challenging.

Likewise, having to care for a sick animal can be emotionally distressing for the owners. Caregivers of chronically sick dogs report feeling hopeless and powerless, especially when they cannot help to alleviate their dogs’ suffering.

Other factors, such as the pet’s behavioural problems and the grief experienced after losing a pet, can also be difficult for owners. For those contemplating adoption, it’s important to take these realities into account to make an informed decision.

Meeting our pet’s needs

There are many important factors to consider when welcoming a new animal companion into our homes. Above all, we need to ensure we have the time, energy and resources to meet their needs.

Choosing a pet carefully, based on what we realistically can offer and on reliable information about their characteristics and needs, gives us the best chance of having a positive and successful relationship.

For better or worse, your dog’s behaviours can impact your quality of life


Supporting our pets’ needs can also improve our own well-being as owners, showing the potential for mutually beneficial interspecies relationships. But when those needs are not met, both pets and their owners can end up feeling stressed and unwell.

When considering adopting a pet, it’s important to ask: why do we want a pet? If the idea is to improve psychological well-being, our research suggests we might need to think again.

Vaccine hesitancy: How social and technological issues converged to spawn mistrust

Source: The Conversation – Canada – By Emanuele Blasioli, PhD Candidate in Management Science, DeGroote School of Business, McMaster University

The rise in vaccine-preventable diseases around the world is threatening decades of progress in public health and putting millions of people at risk.

The decline in vaccination coverage in the United States illustrates the global problem. Rates of most routine vaccinations recommended for children by age 24 months by the Advisory Committee on Immunization Practices, which focus on 15 potentially serious illnesses, have declined.

Canada has not been spared from this phenomenon. As of July 19, there have been 4,206 measles cases (3,878 confirmed, 328 probable) in 2025 reported by 10 jurisdictions (Alberta, British Columbia, Manitoba, New Brunswick, Northwest Territories, Nova Scotia, Ontario, Prince Edward Island, Québec and Saskatchewan).

This decline in vaccine coverage is often attributed to misinformation and disinformation. As data analytics researchers, we used operations research techniques to understand why people are vaccine-hesitant. In our study, we explore how anti-vaccination sentiments and attitudes can be better understood through an integrated approach that combines social network analysis with insights into psychological reactance and the influence of eHealth literacy on health-related behaviours.

So what fuels skepticism about vaccines? It’s a complex blend of personal, social and environmental factors.

How our brains decide (and often get it wrong)

People typically use mental shortcuts, known as heuristics, to simplify complex issues.

The purpose is to minimize analytical efforts and speed up decision-making, which can sacrifice accuracy for the sake of efficiency. This results in distortions known as cognitive biases, which influence judgment and decision-making.

Vaccination decisions are influenced by these processes in the same way as any other decision.




Read more:
How cognitive biases and adverse events influence vaccine decisions (maybe even your own)


Skepticism toward vaccines has often been associated with fears related to possible side-effects. These fears are fuelled by our broad tendency to overestimate negative consequences, a mechanism known as risk-perception bias.

A recent study published in Nature Scientific Reports confirmed that vaccine-hesitant individuals are more sensitive to risk, and give undue weight to potential side-effects.

Another study, from the journal Vaccine: X, looked at cognitive biases related to vaccine hesitancy and revealed four factors significantly associated with hesitancy. These are:

  • fear of vaccine side-effects (skepticism factor),
  • carelessness about the risks of not being vaccinated (denial factor),
  • optimistic attitude, believing they are less at risk of illness (optimistic bias factor) and
  • preference for natural products (naturalness bias factor).

Existing beliefs can also significantly interfere with evaluations and decisions, since people are inclined to seek information that reinforces and confirms their convictions. Confirmation bias interferes with the rational evaluation of evidence related to vaccine safety and efficacy.

The effect of this bias becomes particularly relevant when analyzing how susceptible individuals are to misinformation — a major barrier to vaccine uptake.

The myth of rationality

Assuming human beings can make fully rational decisions is helpful for developing simulations and models, like those in game theory. Game theory is a powerful analytical tool often used in operations research to understand phenomena arising from the interaction of multiple decision-makers, allowing us to predict the possible scenarios that may unfold.

Insights from behavioural economics and cognitive psychology suggest that any assumption of rationality is often wildly optimistic.

Bounded rationality” describes the constraints within which reason operates. Human judgments suffer from a scarcity of information, time limitations and our limited ability to analyze.

Still, even the most effective information would not be enough to convince all vaccine-hesitant individuals. In some cases, it can have the opposite effect.

Understanding psychological and attitudinal predictors of vaccine hesitancy allows us to compare their influence in different contexts. Contexts define the environmental background (or setting) in which individuals decide about the vaccine.

These comparisons show that thought patterns and attitudes that feed into vaccine hesitancy can be modified, unlike stable risk factors, including demographic factors, such as unemployment, lower education, younger age, rural residency, sex and migrant status.

Change in vaccination decision over time

Immunization behaviours evolve over time, influenced by social dynamics. Researchers have studied why voluntary vaccination programs for childhood disease sometimes fail, showing how self-interested decision-making leads to lower vaccination rates and prevents the complete eradication of the illnesses that vaccination could otherwise control.

Assuming parents can make perfectly rational decisions, the study outlined two scenarios:

  1. The benefit of vaccination for their child, accepting there might be some risk of side-effects;

  2. The benefit of not vaccinating, knowing they can avoid side-effects, and hoping their child won’t catch the disease.

Whenever these choices seem equally good to parents, the researchers found there is a critical drop in vaccination uptake, especially for highly contagious diseases.

Another study investigated why vaccination rates swing wildly up and down over time instead of remaining steady.

The authors focused on how people copy each other’s behaviour and looked at two actual vaccine scares that happened in England and Wales, one in the 1970s with whooping cough vaccine and another in the 1990s with the measles, mumps and rubella (MMR) vaccine.

They found that parents oscillated between vaccinating and not as they followed the herd in whatever choice seemed safest, causing boom-and-bust cycles and unstable community protection from the targeted illnesses.

Such dynamics can also result in localized pockets of under-vaccination that benefit the unprotected through herd immunity, but also risk unvaccinated groups becoming high-risk clusters if that protection deteriorates.

Echo chambers in social media

The COVID-19 pandemic has proven how damaging misinformation, disinformation, information voids and information gaps can be to public health, including immunization coverage and vaccine hesitancy.

The relationship between social media misinformation and vaccine hesitancy can be understood by looking at two elements: how much individuals are exposed to it and how persuasive social media is.

At the height of the COVID-19 pandemic, vaccine-skeptical content on social media had a significant negative effect and fuelled doubts about vaccine safety and effectiveness, particularly when not subjected to flagging by fact-checkers.

The impact of unflagged vaccine-skeptical content in driving vaccine hesitancy was estimated to be 46 times greater than flagged misinformation content.

Factually accurate but potentially misleading content — such as a rare instance where a young, healthy individual passed away shortly after being vaccinated — also plays a critical role in driving up vaccine hesitancy.

In our own research, we and our collaborators argue that investigating the role of social media networks can help us develop new strategies to promote and increase evidence-based vaccine literacy.

Should back-to-school require parent fundraising? Ontario schools are woefully underfunded, and families pay the price

Source: The Conversation – Canada – By Lana Parker, Associate Professor, Faculty of Education, University of Windsor

Back-to-school is around the corner, which means that many parents will soon receive requests from schools to pay fees, contribute supplies or support fundraising activities.

But many families are already shouldering significant financial concerns. This raises the question why Ontario schools have become so reliant on direct fundraising contributions from parents.

Though the Ontario government insists it has never spent more money on education, a closer look at the facts and figures reveals that the budget allocated to education is woefully short of covering necessities.

My research, “Infinite Demands, Finite Resources: A Window into the Effects of Ongoing Underfunding and Trends of Privatization in Ontario Schools,” draws on discussions with educators to share insiders’ perspectives on how underfunding looks and feels in schools.

Increased demands, shortfalls

The Canadian Centre for Policy Alternatives (CCPA) released a 2022 report showing that, even amid the increased complexity of teaching during the pandemic, the Ontario government increased class sizes, cut funding and teaching staff and continued to permit the backlog for school infrastructure repair to balloon to nearly $17 billion.

Using the current government’s budget projections, Ontario’s Financial Accountability Office has forecast the education system will see a $12.3 billion shortfall over the next decade.

While some people might ask whether these cuts are a marker of prudent financial stewardship, the numbers once again reveal a different story.

The CCPA report showed that while Ontario had robust GDP growth of nine per cent in 2021 and 6.6 per cent in 2022, Ontario’s Financial Accountability Office found that, in 2017, “overall program spending in Ontario averaged roughly $2,000 per person, per year less than the average of the other provinces.”

In other words, the province has adequate funding, but is choosing to under-serve certain portfolios. For example, Ontario announced in its latest budget it will invest $28 billion on highways over 10 years.

Public investment with future returns

The choice to underfund education is shortsighted because research shows education is a public investment that can generate a high level of future returns.

This under-investment in education has real consequences for the day-to-day quality of schools. Parents who have children with special education needs have long been raising the alarm that their children lack access to adequate testing and supports, which is a direct function of insufficient funding.

Ontario’s principals, teachers and other educators issued an urgent statement in February 2025 advising the public of chronic underfunding and subsequent system challenges that “threaten the very foundation of the education our children and young people deserve.”

How boards are managing shortfalls

My recent research shines a light on the need for more sustainable funding.

The 11 highly experienced educators and one education organizer in my study described how school boards are trying to manage budget shortfalls by asking schools to increase fundraising and by asking school principals to look for private sector contributions.

They discuss how fees are becoming commonplace for extracurricular activities, which places a burden on families.

They decry the loss of materials for school libraries, arts programs and performance spaces. And they warn that the system cannot take many more years of disinvestment.

Full scope may not be clear to parents

Because educators are employed by public school boards and are responsible to the Ministry of Education, they might not be empowered to express their concerns to parents directly. Even parents who participate in school council meetings or fundraising efforts may not understand how much of an issue education underfunding is in their child’s school.

However, with their decades of experience, the educators in my study are unambiguous about the current situation.

One educator shared, “The students who suffer the most are the ones who are in our ESL programs and who are in our special education programs.”

Another noted, “With the formulas that would have been used pre-pandemic, I would have had four and a half, maybe five special education resource teachers and last year I had fewer than two.”

Yet another revealed, “There’s hundreds of kids in our neighbourhood who have never had a music teacher.” Another spoke about playgrounds, noting their board was being encouraged to seek private donations:

“That was part of the message we got the other day: ‘Look over to this school. The
[foundation name] came and built their playground. Maybe y’all should try that.’ We’re being told that we should be seeking out these donations. That’s highly problematic.”

Music also matters in the real world


These are losses of public education goods and services that not that long ago would have been available to all children.

As one of the participants noted:

“There are a number of opportunities that used to exist that no longer exist, and then parents get upset because they think, ‘Well, when I was in school, all of this was around. What happened?’ … Really, it’s about the underfunding.”

Province appointing supervisors

Recently, the Ontario government appointed supervisors to some boards, announcing that “investigations showed they each had accumulated deficits.”

In so doing, the government is asserting more control over public education and runs the risk of political partisanship (one of the appointed supervisors is a former Progressive Conservative MPP).

Journalist Wendy Leung with The Local, who has covered the significance of these appointments, reports the move also “hampers public scrutiny over what’s happening at the boards.”

Taking over boards can be seen as a distraction tactic as the government is asking them to meet growing needs with fewer resources.

Instead of increasing funding, which is necessary and long overdue, the government is likely to cut costs in the short term by privatizing services, a trajectory researchers have documented for some time. These shifts to the private sector are shortsighted attempts to balance a budget that only serve to raise the taxpayer burden over time.

People in Ontario — and across Canada — should be proud of our public education systems. They are held in high regard globally. But education requires ongoing financial investment in our children’s futures.

It took robust political will to compel governments to offer free public education to all children.

This history suggests it will take ongoing pressure from parents applied directly to the Ministry of Education, or via engagement with school councils and school boards, to demonstrate their desire for fair and sustainable public schooling and ensure governments do not shortchange education.

In this way, support for children today will be improved, and the proud inheritance of public education will be strengthened and viable for generations to come.
