Austin Bowden-Kerby, a pioneer in coral reef conservation, spends many of his days gardening corals for reefs around Fiji and the Pacific. He grows corals in ocean nurseries. Once they’re healthy enough, he moves them to outer ocean areas with the hope they will replicate and grow.

“We’re looking at what Mother Nature would do on her own if she had 1,000 years to adapt,” said Bowden-Kerby, who founded the UNESCO-endorsed Reefs of Hope strategy. “We would have these kinds of things happening.”

Bowden-Kerby is one of several scientists trying to conserve, replicate and reproduce heat-resistant corals before climate change wipes them out.

The United States National Oceanic and Atmospheric Administration has said the world is experiencing a fourth global coral bleaching event. They’ve found that bleaching-level heat stress affected almost 85 per cent of the world’s coral reef area between 2023 and 2025.

Bleaching causes corals to lose their food source and, with it, their colour. Most corals survive in temperatures between 20 and 29 C. But as ocean temperatures rise, it’s difficult for many to thrive.

But naturally occurring, heat-resistant corals can survive in waters up to 36 C and potentially higher. They are usually found in warmer waters, like parts of the Pacific Ocean and the Persian Gulf. These corals are increasingly important as sea temperatures rise. So scientists are turning to them to help save declining reefs.

Corals reefs are extremely diverse places, with around 6,000 coral species worldwide. Reefs are home to more than 4,000 species and 25 per cent of global marine life. When healthy, corals nurture fish that feed communities, protect shores from floods and storms
and boost economies through tourism.

However, heatwaves have led to widespread coral bleaching and loss. When waters become too warm, corals expel the algae in their tissues that give them their colour. That causes corals to turn completely white.

Coral reefs and their ecosystems are also threatened by pollution, ocean acidification, coastal development and overfishing.

Will 2026 be the year when coral reefs pass their tipping point?


Christopher Cornwall, a lecturer in marine biology at Te Herenga Waka-Victoria University of Wellington in New Zealand, co-authored a recent review that found some reefs can survive if corals become more heat-tolerant.

He told me there are multiple things to consider when conserving and replicating corals: restoring heat-resistant corals where it’s feasible, doing so at a large enough scale and maintaining coral diversity. Restored corals also must be able to survive, he added.

“We can’t just do coral restoration without thermally tolerant corals, because they’re just going to die the next time it gets too hot,” Cornwall said.

Assisted evolution

“A lot of the research now is about, can you scale up restoration and how do you do it more effectively?” said Peter Mumby, a professor of coral reef ecology at the University of Queensland in Australia. “One of the key concerns is to make sure those corals are as tolerant of high temperature as possible.”

Breeding heat-tolerant corals is a form of assisted evolution. Humans intervene to speed up natural processes to help corals more quickly respond to and recover from their stressors, like heatwaves from climate change.

One recent study examining the possible success of assisted evolution interventions like breeding and selecting traits found these interventions can help corals become more tolerant to heatwaves, but they need “extremely strong selection.”

Liam Lachs co-authored that study. Lachs is a former postdoctoral research associate in the CORALASSIST lab, a team of scientists led by James Guest at Newcastle University in the United Kingdom. Lachs specializes in coral reef ecosystems and researches coral in Palau, a Pacific island country where corals are surviving in warmer waters.

He told me variability within and among reefs and coral species must be considered when creating more heat-resistant coral, which makes replication complex. “Even within a single reef, there’s a range of tolerance levels,” he said.

Algae and bacteria

Researchers at the Australian Institute of Marine Science (AIMS) have found that some algae (Durusdinium), which symbiotically live in corals and provide them with food in exchange for housing and protection, can boost corals’ heat tolerance.

Madeleine van Oppen is a senior principal research scientist at AIMS. She co-authored a recent review about potentially introducing beneficial bacteria into corals to improve their heat tolerance.

Scientists are also exploring whether heat-tolerant corals should be planted across oceans — from the Indo-Pacific region to the Caribbean — and not just in nearby waters.

Van Oppen said new ventures ultimately need more research, and the real test of success is if something done in a lab works in the wild. “Field testing, I’d say, is the next big thing,” she said. “Finding out whether these interventions can enhance tolerance at ecologically relevant scales. Is it stable over time?”

AIMS researchers also found that heat tolerance could be passed down by interbreeding wild colonies of the same coral species. Heat-resistant coral species include some pocillopora and acropora.

If left unchecked, the sustained global temperature is on target to rise more than 1.5 C. Some evidence has shown that 70 to 90 per cent of tropical coral reefs could go extinct even if global warming is limited to 1.5 C.

Prior to the fourth event, the Earth already experienced three mass coral bleaching events over the last few decades. An El Niño is expected this year, bringing with it hotter sea surface temperatures, much like in 2024.

For all the efforts by scientists to save coral reefs and ensure heat resilience, nothing will keep corals healthy more than lowering the global temperature. “The lower we can get our greenhouse gas emissions, the more chance there will be that reefs will exist in the future,” said Cornwall.

Diaspora distress: When geopolitical conflict follows immigrant workers into the office

Source: The Conversation – Canada – By Amir Bahman Radnejad, Chair and Associate Professor of Innovation and Marketing, Mount Royal University

Rostam does not sleep through the night anymore. At 2 a.m., when his phone buzzes, he’s awake before the sound finishes. It might be his parents calling from Tehran, on a connection that is unreliable, sporadic and sometimes cut off mid-sentence. He has learned not to miss those calls, because the next one may not come for days.

Rostam is a pseudonym for a participant in our ongoing research study on diaspora workers, but his experience is one that many workers across Canada will recognize.

Rostam checks the news constantly, piecing together what is happening. Since the United States and Israel launched joint strikes on Iran in late February, the conflict has escalated rapidly. By 4 a.m., he has been awake for two hours. This is hypervigilance: the body monitoring a threat it cannot act on and refusing to stand down.

When the call does come through, the relief is physical. They are alive. They speak carefully, partly to protect him and partly because the call may be monitored. He hears his father’s voice and thinks this could be the last time.

In the morning, he will go to work. He will sit in meetings, contribute to agendas and make sure his face doesn’t betray what he’s feeling — a competency that has always served him well.

He doesn’t speak about any of this at work. To talk about it risks being regarded as a representative of a country he has complicated feelings about or as importing politics into a space that doesn’t want them. So he says nothing. That silence is the problem.

The invisible cost at work

Decades of research have established that code-switching — the constant calibration of self-presentation across cultural contexts — carries a real psychological toll on workers. It can contribute to stress, anxiety, burnout and costly errors in judgment at work.

These impacts often remain invisible to employers until the damage has already been done to both the individual and the organization.

Diaspora employees who are struggling don’t signal it in ways that trigger organizational concern. They manage, but at considerable personal cost. These costs accumulate in ways that surface slowly and are almost always misattributed. Declining engagement is read as a shift in attitude, and withdrawal is interpreted as a personality change.

In some cases, employees do not withdraw at all. Instead, they bury themselves in work and appear by every visible metric to be thriving. Managers have no reason to look closer until the break happens.

This isn’t a problem that diversity, equity and inclusion programs can solve as they exist, because it’s not about inclusion or diversity. It’s a perceptual problem: leaders don’t see what diaspora employees are managing and therefore cannot respond to it.

Diaspora communities carry the burden of watching war from afar


A condition without a name

This challenge extends well beyond Canada’s Iranian community, which numbered approximately 200,000 people in the 2021 census. Many other diaspora communities, including Ukrainians, Palestinians, Sudanese, Afghans and Syrians, are navigating similar terrain.

A 2025 study found higher rates of severe depression, anxiety and post-traumatic stress disorder among diaspora Tigrayans in Australia than among people inside the war zone itself.

People inside a conflict zone often suppress their own fear to protect family members living through it with them. Members of the diaspora, by contrast, often cannot meaningfully assist those in immediate danger, which creates a profound sense of helplessness. At the same time, those around them may not recognize the fear and distress they’re concealing.

Aitak Sorahi, an Iranian Canadian, tried to explain what she was living through to a reporter at The Canadian Press in April as U.S. President Donald Trump threatened to destroy Iran unless it agreed to reopen the Strait of Hormuz. She could not find the words. “I don’t even know how to describe my feeling,” she said, “because I don’t have a name for it.”

We propose one: diaspora distress, a framework emerging from our ongoing research and organizational practice.

Diaspora distress

Diaspora distress is the psychological burden carried by people living in one country while their homeland — and the family, friends and memories embedded there — are under active geopolitical threat. Often, this burden is compounded by the policies or rhetoric of their host country’s own government.

The feeling sits closest to grief, but the comparison only goes so far. Grief has a fixed point — a death, a diagnosis, a loss that has occurred and can be named. It comes with a recognized social script: people sit together and are able to share memories of the deceased. Diaspora distress offers no comparable ritual because the loss one is anticipating may or may not arrive.

In addition, diaspora communities are not monolithic. Outsiders often assume a shared solidarity, but geopolitical crises tend to deepen existing internal divisions about what intervention means, who is to blame and what liberation looks like. The people who should be each other’s community of grief often find themselves on opposite sides of an argument.

The result is that diaspora employees are frequently alone with this in every environment they occupy: at work, at home and within communities that might otherwise support them. That isolation is the specific nature of diaspora distress.

What organizations should do

Developing the capacity to recognize diaspora distress does not require expertise in geopolitics or new policy infrastructure. It requires language: the organizational decision to name what some employees are carrying as a recognized condition.

Institutional acknowledgement works differently than other supports because it removes the requirement that employees claim what they’re carrying. It gives them a name for what they have been living with.

In practice, this can take three forms: a leadership message acknowledging that some colleagues are carrying weight from events in their home regions; a line added to standard manager check-in prompts asking whether anything outside work is affecting employees; or an addition to existing employee assistance programs and benefits communications that names diaspora distress explicitly.

Rostam will open his phone again tonight at 2 a.m. In the morning, he will code-switch from the person who spent the night reading the news into the person his organization knows. What remains is whether his organization will adopt the language to see it, and whether his leaders will decide that seeing it is part of their job.

To lead in global innovation, Canada must prioritize basic science

Source: The Conversation – Canada – By Shay M. Freger, PhD Candidate and Clinical Researcher, Department of Obstetrics and Gynecology, McMaster University

A healthy Canadian research ecosystem cannot survive on the final stages of innovation alone. (Unsplash)

Canada’s National Research Council boldly advertises itself as “advancing mission-driven science and innovation” — to strengthen national security, economic resilience and global competitiveness.

This ambition is difficult to reconcile with a national research system that has, for years, placed too little value on the basic, exploratory, investigator-led science that makes those outcomes possible.

In 2017, Canada’s Fundamental Science Review found that federal funding had shifted too far toward priority-driven and partnership-oriented research. In 2023, the Advisory Panel on the Federal Research Support System made a similar point: mission-driven research depends on the strength of the broader research ecosystem, including curiosity-driven work.

Recent federal investments in research infrastructure, including more than $552 million through the Canada Foundation for Innovation, are important. They help universities, hospitals and research institutions acquire laboratories, equipment and facilities to conduct world-class research.

However, a healthy research ecosystem also needs stable and sustained operating support for investigator-led work. This includes the early, uncertain studies that identify tomorrow’s neglected problems before they become today’s policy priorities.

A nation’s ‘scientific capital’

Health research shows why this distinction matters. We celebrate new treatment advances such as CAR T-cell therapy, which genetically engineers a patient’s immune cells to attack cancer. We welcome CRISPR-based therapies such as Casgevy, a gene-edited cell therapy for sickle cell disease and transfusion-dependent beta-thalassemia.

But these advances did not appear fully formed. They were built through years of work in molecular biology, immunology, genetics, chemistry, engineering and clinical science, much of it conducted before anyone could promise a product, a company or a clinical payoff.

That foundation is fragile when it is treated as optional. As American science adviser Vannevar Bush said back in 1945, basic research is the source of a nation’s “scientific capital.” The Organisation for Economic Co-operation and Development (OECD) continues to make this case clearly today: public support is essential for research and innovation.

A healthy Canadian research ecosystem cannot survive on the final stages of innovation alone. Of course, it needs applied research, commercialization and measurable impact. But it also requires the earlier, “high-risk” discovery work that expands the horizon of what is possible.

Special calls are not enough

Endometriosis makes the problem concrete: it affects many people in Canada, is associated with pain, infertility and reduced quality of life. Canadian research has reported an average diagnostic delay of 5.4 years.

In fields like this, upstream science is not a luxury. Before better diagnostics and treatments can exist, researchers have to ask basic questions about inflammation, pain, immune function, hormones, nerves, genetics, imaging and disease progression.

As researchers working in reproductive health, we have seen how targeted federal grant calls can elevate under-researched conditions. The National Women’s Health Research Initiative, for example, was designed to address high-priority areas of women’s health and improve care for women, girls and gender-diverse people.

This kind of targeted funding matters. It can create momentum and build networks. But it cannot carry a research system on its own. Targeted calls are often time-limited, theme-specific and shaped by priorities that are already visible enough to attract policy attention.

The case of mRNA vaccines

During the COVID-19 pandemic, mRNA vaccines looked to many people like a scientific miracle delivered at unprecedented speed. But that apparent speed was misleading. The vaccines did not emerge from nowhere.

The 2023 Nobel Prize in Physiology or Medicine recognized Katalin Karikó and Drew Weissman for discoveries that enabled effective mRNA vaccines against COVID-19. Their work helped solve a central problem: how to make mRNA useful as a medical tool without having the body immediately recognize and destroy it as a threat.

Even that breakthrough rested on a much wider scientific history, involving around 50 years of public and private research. Scientists had to understand how mRNA carries genetic instructions, how cells translate those instructions into proteins, how immune systems detect foreign RNA and how fragile mRNA could be delivered safely into cells. None of that work was a vaccine when it began. Yet without it, the vaccine could not have arrived when it was needed.

This is why short-term thinking in science policy is so risky. If research is valued only when it can explain its payoff in advance, systems will gradually favour projects that are safer, narrower and more immediately tangible. That may produce useful results in the short term, but it weakens the broader discovery pipeline over time.

Reliance on other nations

There is a strong economic case for paying attention. A 2024 study of 15 OECD countries found that public investment in research and development had positive and persistent effects on GDP and also stimulated business research and development investment.

Public support for long-term research is not separate from economic strategy. It is part of how countries build it. But the deeper issue is not only economic. It’s whether Canada wants to remain a producer of knowledge or become increasingly dependent on knowledge produced elsewhere.

A country that under-invests in basic research does not stop benefiting from science. It becomes more reliant on other systems to take the early risks, generate the foundational knowledge and shape the next generation of medical, technological and industrial advances. Canada’s Fundamental Science Review warned that continued imbalance in funding would leave the country increasingly dependent on discoveries and ideas generated abroad.

This impacts our health, climate science, energy and emerging technologies. It’s important in terms of how well Canada can respond to future crises. And it matters whether neglected areas of health and science ever receive the depth of inquiry required to produce real change.

Canada must protect upstream research

Canada should not have to choose between useful and ambitious science. These are not opposing goals. They are different points along the same continuum. Today’s basic research becomes tomorrow’s applied science. Today’s obscure mechanism becomes tomorrow’s therapy.

Today’s difficult question may become tomorrow’s platform technology. But only if someone is allowed to ask it.

Canada needs targeted programs. It needs research infrastructure. It needs commercialization possibilities that help discoveries reach patients, communities and markets. It needs sustained investment in investigator-led research.

That means protecting operating grants from erosion, funding trainees and early-career researchers, supporting high-risk work in neglected fields and evaluating scientific value by more than immediate commercial readiness.

This is not indulgence. It is foresight.

Canada’s fragmented electronic health records harm patients and cost taxpayers billions: New research

Source: The Conversation – Canada – By Braden Manns, Professor of Medicine and Health Economics, University of Calgary

In most Canadian provinces and territories, patient health information is siloed in separate software programs in different offices, designed by multiple vendors with differing standards. (Unsplash)

Canada’s health systems began shifting from paper charts to electronic health records decades ago. These records hold patients’ critical health information, including medications, diagnoses, clinical notes, test results, specialist consults and plans for care.

Our research, published today in the Canadian Medical Association Journal, raises major concerns about the state of these electronic health records nationwide.

In most provinces and territories, information is currently siloed in separate software programs in different offices, designed by multiple vendors with differing standards. This fragments patients’ health records across services and leaves clinicians without the information they need to provide safe care.

This is harming patients, costing taxpayers $9.4 billion annually and hindering health-system improvement.

Canada’s missed opportunity

Ideally, patients’ health information should follow them over time and across locations. Some might assume that’s how it works now. After all, hotel chains remember whether we prefer foam or feather pillows, no matter what country we are in. Uber ratings follow us everywhere.

Unfortunately, in health care, things aren’t so seamless. In the rush to abandon paper charts and transition to electronic records, Canada missed a major opportunity for standardization.

Without an overarching plan, clinics, hospitals and jurisdictions chose from dozens of incompatible platforms sold by vendors competing for market share, without considering the need for personal health information to follow the patient.

A provincial and territorial legislative focus on the privacy of patient records has also fostered an environment that splinters patient information between health services.

The Connected Care Scorecard

Collecting, tracking and exchanging patients’ health information is key to safe, co-ordinated care. In some jurisdictions, like Taiwan, electronic health records from different vendors dock securely together. If a family doctor changes a medication, then pharmacy, hospital and specialist records are automatically updated. A treatment plan from a specialist lands directly in a family doctor’s electronic record, without need for faxing, scanning or uploading.

In Canada, hospitals, specialists and primary-care services still rely heavily on fax machines and mail, rather than automated, instant, accurate data exchange.

As part of our research, we created a Connected Care Scorecard that reveals where each province and territory stands in connecting its health records.

the connected care scorecard
Curious how interoperable your home province or territory’s electronic health records are?
(Connected Care Scorecard)

In British Columbia, for example, dozens of incompatible electronic health record systems are used in community clinics alone. Hospitals, even within the same health authority, run on different platforms. A patient who visits an emergency room in downtown Vancouver will have to tell their story again if they later seek care in Burnaby. Clinicians may end up retesting for illnesses already ruled out.

Prince Edward Island does much better — with one electronic health record uniting all hospitals and a single platform for primary-care clinics. The hospital record feeds information into primary care so details are available for follow-up.

Interoperability matters

Connected, integrated electronic health records allow all clinicians to work together on a common plan. Sharing patient information is critical for team-based care. It improves outcomes like medication safety and enables patients’ access to records, making them part of the care team.

Most jurisdictions do have patient portals where some people can see portions of their health information, like lab results or prescriptions. However, a 2025 study found that only 13.2 per cent of adult Canadians have electronic access to such records.

Despite tremendous hype and opportunity to improve care through artificial intelligence, most health systems can’t use it at scale. That’s largely because the opportunities it offers — assisting with diagnoses and prompting clinicians to order the tests and treatments patients need — are wholly dependent on ready access to comprehensive, accurate patient health data.

Interoperable electronic health records would also help health systems access population-based information to inform planning. Data could help predict disease outbreaks and spot bottlenecks in hospital flow. It could improve cancer care and ensure patients with the greatest needs are prioritized.

Our research shows that although most jurisdictions use some hospital data for planning, information in electronic health records, especially from primary care, rarely gets used to improve health systems. This has long-term implications: you can’t manage what you don’t measure.

All of this adds up to massive costs for taxpayers, patients and clinicians.

Common health data standards

The federal government recently reintroduced the proposed Connected Care for Canadians Act, which would require vendors to adopt common standards for exchanging information across systems. It’s a solid first step, but more is needed.

Most importantly, governments must establish clear accountability — nationally, provincially and territorially — for health data oversight. This must balance minimizing privacy breaches with limiting all other forms of harm arising from disconnected records, including damage to patients, clinicians and health systems.

Jurisdictions must also establish common health data standards, tools and incentives to improve data coordination.

Our challenge is not adopting electronic health records, but connecting them. Without that, our investment simply won’t pay off. Care will continue to suffer.

Chinese and Canadian approaches to math teaching have a lot to learn from each other

Source: The Conversation – Canada – By Chenkai Chi, Postdoctoral Research Fellow, Educational Studies, University of Windsor

What kind of education best helps students learn math?

In the province of Ontario, the most recent provincial standardized results (2024–25) show modest improvement in elementary mathematics achievement, but overall performance remains uneven, particularly in the junior grades.

Provincially, 64 per cent of Grade 3 students met the provincial standard, up from 61 per cent the previous year. In contrast, only 51 per cent of Grade 6 students met the standard, indicating that about half of students are not yet achieving expected levels by the end of the junior division.

Student attitudes toward mathematics also decline with age: while 67 per cent of Grade 3 students reported liking mathematics, this dropped to 48 per cent in Grade 6.

These results suggest gradual recovery following COVID-19 pandemic disruptions, but they also point to the necessity for more work to be done for both teachers and students to develop a deeper understanding of the 2020 math curriculum. This curriculum incorporated new priorities like social–emotional learning, coding, mathematical modelling and financial literacy.

6 changes in Ontario’s not-so-basic new elementary math curriculum


My research has examined Ontario math education taught by generalist elementary school teachers in dialogue with Chinese mathematics instruction taught by specialist math teachers. Grounded in this work, I believe we should firstly be proud of Ontario math education instead of criticizing it.

This research was part of a partnership grant project from the Social Sciences and Humanities Research Council, with education researchers Shijing Xu and Michael Connelly.

Dialogue between teachers

In our research with a “Sister School Network” project, generalist elementary teachers from a Windsor, Ont. public school and mathematics specialist teachers from a Chongqing, China primary school participated in monthly online knowledge-sharing meetings.

At the meetings, teachers shared and compared curriculum. They offered demonstrations on topics such as fractions, multiplication and estimation, and discussed student learning and parent engagement.

From 2016 to 2019, Xu and I co-ordinated these monthly exchanges and organized visits of Canadian teachers to Chongqing as well as Chinese teachers’ visits to Windsor.

Other sister schools that are part of Xu and Connelly’s project include Shanghai-Toronto, Shanghai-ChangChun and Windsor-Beijing.

Special education, professional autonomy

Chinese mathematics specialist teachers deeply appreciated the strengths of Ontario’s generalist model — particularly the comprehensive learning support provided to students with diverse needs and the high level of professional autonomy granted to teachers.

One Chinese participant with more than 20 years of mathematics teaching experience reflected:

“I wish we could have a special education support system like in Canada.”

Such perspectives highlight a key strength of Ontario’s elementary generalist system — one that educators in the province can take pride in. In an interview I did with mathematics education researcher Christine Suurtamm, whose research has engaged international perspectives on mathematics education and Canadian teachers’ practice, Suurtamm noted:

“I think the idea that we have great faith in teachers’ professional judgment to work with a curriculum, and to determine the best way to sequence and select the kinds of activities that address the curriculum expectations and meet their students’ needs, is a real benefit to our students in Ontario. I think that is something we should be proud of.”

Value of working with a specialist

In my study, a Grade 5 Canadian teacher also appreciated the opportunity to co-plan and co-teach with a Chinese mathematics specialist teacher. In interviews, the teacher emphasized a deep appreciation for this collaborative approach and expressed the hope that Canadian schools could provide more structured opportunities for such professional collaboration.

In my interview with Suurtamm, she also noted it would be worthwhile if Ontario teachers had more time to develop their math lessons in collaboration with other teachers.

In 2023, Ontario announced funds to double the number of school mathematics coaches. Research about how and where the coaching model has been implemented, how teachers are relying on it and its real effects in the classroom would help gain insight into the efficacy of this approach.

Challenges with Ontario math education

My research also suggested ways Ontario mathematics education might learn from Chinese mathematics learning.

Two key challenges emerge in Ontario mathematics teaching. First, teacher collaboration is limited. Unlike Chinese mathematics specialists who routinely engage in co-planning, lesson observation and collective reflection, Canadian generalist teachers have few structured opportunities for sustained collaboration, despite a clear desire for it.

Second, the consolidation of mathematical learning seen in Ontario is relatively weak. One Chinese math specialist teacher described teaching mathematics as a dynamic balance between Fang (放) — encouraging open exploration and the use of multiple strategies — and Shou (收) — a structured consolidation phase. In this phase, key ideas are clarified, connections are synthesized and methods are formalized.

Ontario educators and policymakers may consider these insights in ways that are responsive to local situations.

Curriculum and approaches evolve

Overall, my collaborative research views improving mathematics teaching and curricula as an ongoing and progressive process.

As Suurtamm notes, curriculum changes should be approached as an evolution rather than a revolution. Changes build thoughtfully on existing foundations rather than seeking to replace them wholesale.

Before pursuing new directions, it is important to reflect on and recognize the strengths that already characterize Ontario’s mathematics education system.

The COVID-19 pandemic exposed the load mothers carry — a burden that’s still being ignored today

Source: The Conversation – Canada – By Jane E. Sanders, Associate Professor, King’s School of Social Work, Western University

The COVID-19 pandemic exacerbated and brought into focus the ongoing disproportionate burden on mothers when it comes to household logistics, child care and financial inequity. It also revealed just how deeply embedded and structurally reinforced that burden is.

When labour that had previously been a shared social responsibility shifted into individual households, the load fell mainly to women. But perhaps even more important is that the true impact of this burden was invisible — even to women themselves.

Data over three years, from 2020 to 2023 — the height of the pandemic — laid bare the reality of a poorly scaffolded social structure. What had been seen as informal or “natural” for women to take on was, in fact, an uneven distribution of labour and responsibility.

That reality has clear economic effects. Canadian women earn approximately 69 per cent of the average salary of men. Mothers’ salaries also decrease by 49 per cent in the year after a child is born and 34 per cent 10 years later, while fathers’ salaries are largely unaffected.

This disparity — often referred to as the motherhood gap or child penalty — increases over time, crosses generations and is rooted in how societies value and distribute care work.

Studying families during COVID-19

Even before the pandemic, women were often responsible for the majority of housework and child care.

This was the status quo when COVID-19 arrived, as social isolation regulations increased family mental-health concerns while simultaneously decreasing social support.

Between January 2021 and August 2023, qualitative data was collected through semi-structured interviews and focus groups that included 113 people — social work students and professionals from King’s University College at Western University’s School of Social Work and the local school board — to examine the impact of COVID-19 on families who participated in the first three years of our Support and Aid to Families Electronically (SAFE) program.

Participants were asked how families were impacted during COVID-19 and the associated restrictions. We did not expect the disproportionate cost of these increased household responsibilities to be invisible.

Our social systems position women, particularly mothers, as the primary load-bearing point, shouldering a concentrated burden within families. When the already inadequate scaffolding of social structures is removed, as it was during COVID-19, the pressure is too concentrated. Policies, social expectations and workplace culture reinforce these imbalances.

Inequality hiding in plain sight

There were stories of mothers juggling working from home with children’s daily needs, balancing in-person work without child care and facing unemployment and financial peril. After each story, and among other questions, we asked if they thought any of this was related to their gender.

Overwhelmingly, the women said, “No.”

The unequal burden of the COVID-19 pandemic on women was evident in the new roles they were required to undertake, the stress associated with these roles and the psychological and emotional impact of these increased expectations.

However, the concentrated weight of this load was not recognized by those bearing it.

The participants in our study did not identify the stories they shared — of job loss, of being an in-home caregiver (daycare provider, food preparer, entertainer, social support) or of providing mental-health case management and support when everything, including in-school learning, closed — as being connected to the fact that they are women.

The responses revealed how deeply gendered expectations are internalized, framed as circumstance or coincidence rather than inequality.

For example, some of the women said they took on more of the household burden simply because they happened to be the ones who were home during the day, while others said they took on more because they were the one working outside of the home during the day. One participant said:

“Whoever was at home dealing with [our] three children, [they’re] not really doing any of the household stuff. And that just happened to be my husband who was always home. [I would] come home [after having] worked, I now deal with kids and dinner, and then I’m also doing all of the household things. This was burdensome, but I don’t really think it was because I [am a woman].”

Even when the cost of this burden was clear, the fact that it was gendered remained hidden. Another said:

“I don’t think I closed down the business because of being a woman. It was just a lot to handle. It was just draining on a day-to-day.”

It was understood that if women are unable to bear the load, foundational social structures could fracture, as one mother observed:

“My mental health had the greatest impact on the mental health and emotional regulation of the entire household.”

The cost of ignoring the burden

There are profound positives to motherhood, and conceding the need for equity and balance does not contradict them. Rather, acknowledging the disproportionate responsibilities related to household well-being, child care, education and financial equity validates women’s struggle to keep up. It also challenges internalized dominant messages for all of us.

The mental health and educational impact of COVID-19 on children, youth and families will be longstanding. The impact on parents, particularly mothers, will be ongoing.

Only once we truly acknowledge this disproportionate burden can we discuss how these expectations fail everyone, particularly during times of structural instability.

Until caregiving and emotional labour are recognized as shared social responsibilities, rather than private obligations borne disproportionately by women, crises like COVID-19 will continue to deepen existing inequalities.

Wars destroy lives and the climate. Why aren’t we counting military emissions?

Source: The Conversation – Canada – By Tamara Krawchenko, Associate Professor, School of Public Administration, University of Victoria

When delegates gathered for COP30 in Belém, Brazil in November 2025, they scrutinized various sectors of the global economy for their contributions to rising greenhouse gases. Agriculture, aviation, steel, cement — all were on the table. One topic not discussed was war.

This isn’t a minor oversight. Militaries are significant contributors to greenhouse gas emissions. Russia’s invasion of Ukraine has generated an estimated 311 million tonnes of what’s known as CO₂ equivalent, comparable to the combined annual emissions of Belgium, New Zealand, Austria and Portugal. CO₂ equivalent is the metric used to compare the warming impact of various greenhouse gases to carbon dioxide.

Recently published research calculated that the first 15 months of Israel’s war in Gaza generated more than 33 million tonnes of CO₂ equivalent, comparable to the combined 2023 annual emissions of Costa Rica and Slovenia.

In February 2026, Israel and the United States launched a war against Iran, joining a long list of other conflicts where emissions go uncounted in global inventories.

These are massive emissions, and they are generated with no formal mechanism to record, report or attribute them, and no accountability for the climate costs that affect people in conflict zones and far beyond.

A recent article by Neta Crawford, a researcher with the Cost of War project at Brown University, highlights how armed forces, militarization and war fuel climate change. She argues that military emissions and conflict-related emissions remain undercounted, even though they undermine efforts to mitigate climate change.

The military emissions gap

Estimates suggest militaries and their supply chains account for approximately 5.5 per cent of global greenhouse gas emissions, which is enough to make them the world’s fourth largest emitter if counted as a country. And that figure only covers peacetime.

This is what researchers call the military emissions gap: the difference in emissions between what governments report and what their armed forces actually emit.

The problem starts with the rules. Under the United Nations Framework Convention on Climate Change (UNFCCC), countries have been exempt from fully reporting military emissions since the Kyoto Protocol negotiations in the 1990s. The United States successfully lobbied for the exclusion on national security grounds.

The 2015 Paris Agreement introduced voluntary reporting. However, as a 2025 briefing from the Conflict and Environment Observatory and Griffith University made clear, the result is a system that is “patchy, incomplete or missing altogether.”

The top three military spenders — the U.S., China and Russia — either submit no data or incomplete, non-disaggregated figures. This is a structural blind spot that excludes one of the most carbon-intensive sectors from meaningful accountability.

What wars cost the climate

Crawford’s study on Gaza provides a comprehensive account of the war’s full carbon cycle. It found that direct combat emissions — jets, rockets, artillery, military vehicles — account for just 1.3 million of the 33.2 million tonnes of CO₂ equivalent.

The vast majority, more than 31 million tonnes, are projected to come from the reconstruction of destroyed infrastructure: nearly 450,000 apartments, over 3,000 kilometres of roads, schools, hospitals and water systems. Rebuilding what war destroys is, climatically speaking, the biggest act of war of all.

A report on Russia’s invasion of Ukraine by the Initiative on GHG Accounting of War found that direct combat emissions constitute 37 per cent out of total emissions between February 2022 and 2026. The war has ignited thousands of fires in forests and wetlands, accounting for 23 per cent of its total carbon footprint.

Russia’s attacks on electrical infrastructure have further released sulphur hexafluoride, a greenhouse gas 24,000 times more potent than CO₂, from high-voltage switching gear. And the rerouting of civilian aircraft around Ukrainian and Russian airspace has added an estimated 20 million extra tonnes of CO₂ equivalent compared to pre-invasion flight paths.

In Iran, it is estimated that the U.S.-Israel war has unleashed over five million tonnes of CO₂ equivalent — largely from infrastructure destruction and energy-related impacts.

None of this appears in any country’s reports on emissions to the UNFCCC.

What needs to change

In July 2025, the International Court of Justice (ICJ) delivered an advisory opinion establishing that states have binding obligations to assess, report and mitigate harms to the climate system. In a separate declaration, ICJ judge Sarah Cleveland stated that those obligations extend to harms resulting from armed conflicts and other military activities.

The UN General Assembly has called for Russia to compensate Ukraine for all damages resulting from its invasion. When wars of aggression are launched, the emissions generated in fighting them, surviving them and rebuilding belong on the aggressor’s carbon ledger. When Russia invaded Ukraine, it generated a climate debt on behalf of the entire planet. The same can be said of other aggressors.

The Intergovernmental Panel on Climate Change (IPCC) is the UN body responsible for assessing the science related to climate change. The IPCC is currently in its seventh assessment cycle, with reports expected in late 2029.

This assessment cycle must include a dedicated report for conflict emissions covering infrastructure destruction, fighting and post-conflict reconstruction. The UNFCCC must make reporting military emissions mandatory and develop a framework for attributing conflict emissions under its Enhanced Transparency Framework.

Civil society and academia have already done the hard work of showing it can be done. Organizations like the Conflict and Environment Observatory have built methodologies from scratch, using open-source data. The science exists. What’s lacking is the political will to enshrine it in global climate governance.

The richest countries spend roughly 30 times more on their armed forces than they contribute in climate finance to developing countries. Global military spending has reached a record $2.7 trillion. This is more than the total $2.2 trillion invested globally in clean energy in 2025.

As conflicts proliferate, the world is committing to an ever-larger unaccounted carbon liability. The climate finance gap is also likely to get worse as countries cut international development aid to direct funds to higher military spending.

Every degree of warming we are trying to avoid is undermined by wars. Accounting for conflict emissions is a vital way to make climate science whole.

Canada’s United Nations abstention on slavery recognition wasn’t neutral — it was a choice

Source: The Conversation – Canada – By Julie Ada Tchoukou, Assistant Professor, Faculty of Law, L’Université d’Ottawa/University of Ottawa

When Canada abstained from a recent vote at the United Nations on a resolution recognizing the transatlantic slave trade as the gravest crime against humanity, the decision may have appeared cautious, even procedural.

It was neither.

Abstention, in this situation, is not neutral position. It’s a firm stance — one that carries legal, political and historical consequences.

A vote about legal meaning, not just history

At first glance, the resolution might seem symbolic; a statement about a past atrocity with a moral status that’s already globally accepted. But in international law, recognition is never merely descriptive. It helps define legal norms and the scope of responsibility.

The category of “crimes against humanity” has evolved significantly since its early articulation at the Nuremberg Trials in the 1940s. What began as a response to the atrocities of the Second World War has developed into an important pillar of international criminal and human rights law.

Identifying the transatlantic slave trade as the gravest crime against humanity isn’t simply restating history. It situates that history within the legal architecture that governs how we understand atrocity, responsibility and redress today.

The resolution passed with 123 votes in favour. The United States, Argentina and Israel voted against it, while 52 states abstained, including the United Kingdom, Canada and all European Union member states, including Spain.

By abstaining, Canada did not opt out of a symbolic gesture. It declined to participate in shaping the legal meaning of one of international law’s most significant categories.

The myth of absention as neutrality

In multilateral diplomacy, absention is usually framed as a middle ground; a way to avoid taking sides. But in practice, especially in process of creating legal norms, absention can function as a form of resistance.

Votes at the UN General Assembly are part of how international norms are consolidated, clarified and sometimes contested. When states abstain from resolutions that seek to expand or develop those norms, they signal hesitation about the direction of that particular legal development.

Canada’s absention therefore raises questions about alignment. It places the country neither among those states affirming a stronger legal characterization of the slave trade nor among those openly opposing it. Instead, Canada now occupies a position of ambiguity — one that may reflect concerns about legal implications, including potential claims for reparations.

But ambiguity isn’t without impact. In the politics of international law, declining to affirm a legal norm can slow its consolidation and weaken its force.

Why recognition still matters

If the transatlantic slave trade is widely acknowledged as a profound injustice, why does formal recognition matter? Because recognition is tied to how harm is measured, narrated and addressed.

Efforts to grapple with the legacies of slavery increasingly involve questions of quantification, of loss, of dispossession and of enduring inequality. Legal recognition, including reports of the UN High Commissioner for Human Rights and the 2001 Durban Declaration and Programme of Action, shapes these process by establishing what counts as a harm of the highest order and therefore what kinds of responses are justified.

This is particularly evident in ongoing debates about reparations, where claims are often grounded in the characterization of slavery and the slave trade as crimes against humanity. Without clear and consistent recognition, these claims face higher legal and political barriers.

In this sense, the resolution isn’t only about the past. It’s about the frameworks through which historical injustice is made visible in the present.

A choice with consequences

Canada has long positioned itself as a supporter of international human rights and the rule of law. Abstaining on the UN’s slavery resolution is at odds with that self-perception.

States may have reasons to be cautious in endorsing specific resolutions about legal responsibility. But those reasons should be clearly stated and open to scrutiny.

Absention avoids that scrutiny. It allows states to sidestep difficult questions about history, law and accountability while maintaining the appearance of neutrality.

But there is no neutral ground in the recognition of crimes against humanity. There are only choices about what to affirm, what to resist and what to leave unresolved.

Canada has made one such choice. It should be prepared to explain it.

The COVID-19 pandemic exposed the load mothers carry — and that burden is still being ignored today

Source: The Conversation – Canada – By Jane E. Sanders, Associate Professor, King’s School of Social Work, Western University

The COVID-19 pandemic exacerbated and brought into focus the ongoing disproportionate burden on mothers when it comes to household logistics, child care and financial inequity. It also revealed just how deeply embedded and structurally reinforced that burden is.

When labour that had previously been a shared social responsibility shifted into individual households, the load fell mainly to women. But perhaps even more important is that the true impact of this burden was invisible — even to women themselves.

Data over three years, from 2020 to 2023 — the height of the pandemic — laid bare the reality of a poorly scaffolded social structure. What had been seen as informal or “natural” for women to take on was, in fact, an uneven distribution of labour and responsibility.

That reality has clear economic effects. Canadian women earn approximately 69 per cent of the average salary of men. Mothers’ salaries also decrease by 49 per cent in the year after a child is born and 34 per cent 10 years later, while fathers’ salaries are largely unaffected.

This disparity — often referred to as the motherhood gap or child penalty — increases over time, crosses generations and is rooted in how societies value and distribute care work.

Studying families during COVID-19

Even before the pandemic, women were often responsible for the majority of housework and child care.

This was the status quo when COVID-19 arrived, as social isolation regulations increased family mental-health concerns while simultaneously decreasing social support.

Between January 2021 and August 2023, qualitative data was collected through semi-structured interviews and focus groups that included 113 people — social work students and professionals from King’s University College at Western University’s School of Social Work and the local school board — to examine the impact of COVID-19 on families who participated in the first three years of our Support and Aid to Families Electronically (SAFE) program.

Participants were asked how families were impacted during COVID-19 and the associated restrictions. We did not expect the disproportionate cost of these increased household responsibilities to be invisible.

Our social systems position women, particularly mothers, as the primary load-bearing point, shouldering a concentrated burden within families. When the already inadequate scaffolding of social structures is removed, as it was during COVID-19, the pressure is too concentrated. Policies, social expectations and workplace culture reinforce these imbalances.

Inequality hiding in plain sight

There were stories of mothers juggling working from home with children’s daily needs, balancing in-person work without child care and facing unemployment and financial peril. After each story, and among other questions, we asked if they thought any of this was related to their gender.

Overwhelmingly, the women said, “No.”

The unequal burden of the COVID-19 pandemic on women was evident in the new roles they were required to undertake, the stress associated with these roles and the psychological and emotional impact of these increased expectations.

However, the concentrated weight of this load was not recognized by those bearing it.

The participants in our study did not identify the stories they shared — of job loss, of being an in-home caregiver (daycare provider, food preparer, entertainer, social support) or of providing mental-health case management and support when everything, including in-school learning, closed — as being connected to the fact that they are women.

The responses revealed how deeply gendered expectations are internalized, framed as circumstance or coincidence rather than inequality.

For example, some of the women said they took on more of the household burden simply because they happened to be the ones who were home during the day, while others said they took on more because they were the one working outside of the home during the day. One participant said:

“Whoever was at home dealing with [our] three children, [they’re] not really doing any of the household stuff. And that just happened to be my husband who was always home. [I would] come home [after having] worked, I now deal with kids and dinner, and then I’m also doing all of the household things. This was burdensome, but I don’t really think it was because I [am a woman].”

Even when the cost of this burden was clear, the fact that it was gendered remained hidden. Another said:

“I don’t think I closed down the business because of being a woman. It was just a lot to handle. It was just draining on a day-to-day.”

It was understood that if women are unable to bear the load, foundational social structures could fracture, as one mother observed:

“My mental health had the greatest impact on the mental health and emotional regulation of the entire household.”

There are profound positives to motherhood, and conceding the need for equity and balance does not contradict them. Rather, acknowledging the disproportionate responsibilities related to household well-being, child care, education and financial equity validates women’s struggle to keep up. It also challenges internalized dominant messages for all of us.

How should schools teach AI? 3 models to consider

Source: The Conversation – Canada – By Hugo G. Lapierre, Professeur adjoint en technologies éducatives, Université de Montréal

Students across Canada are exposed to artificial intelligence (AI) whether through search engines, writing assistants, automated recommendation systems or social media.

That everyday exposure raises a first, fundamental question: What should students should learn about AI? This goal is often described as AI literacy, which combines conceptual understanding with responsible use and critical judgment about AI.

A second, more practical, question is: Where should learning about AI sit in the curriculum? Since education is a provincial responsibility, Canada has no single approach.

Teaching AI literacy in schools builds on what provinces already require students to learn about digital technologies. How provinces do this determines how much time students get, what can be assessed and how teachers must be prepared.

In practice, these different curriculum models, plus the supports to ensure teachers can effectively teach them, will shape whether AI education becomes a set of tips for using apps — or a form of digital citizenship grounded in concepts, ethics and critical thinking.

What AI literacy implies for schools

Several provinces and educator associations have or are developing frameworks pertaining to AI in K-12 education. Several organizations have proposed similar frameworks that specify the concepts and competencies students should develop, or that guide what meaningful AI education would require in schools.

The United Nations Educational Scientific and Cultural Organization sees AI literacy spanning technical understanding and ethical awareness, and names a vision of students as AI co-creators and responsible citizens.

A U.S.-based framework, AI4K12, outlines what students should learn about AI across grade levels, and identifies five “big ideas” about AI: perception, representation and reasoning, learning, natural interaction and societal impact.

The U.S.-based International Society for Technology in Education (ISTE) proposes standards that engage students as empowered learners, computational thinkers, innovative designers and digital citizens.

Digital learning in provincial curricula

Across Canada, provinces integrate digital learning through different models — but note that these models are ideal types. Several provinces combine them. Each model can support AI literacy, but each creates different conditions for time, assessment and teacher preparation.

1. A dedicated subject or domain, where digital skills or computer science have their own courses. In many systems, teachers have been specifically trained for the subject. This configuration typically supports clearer sequencing across grades and more consistent assessment.

For example, between kindergarten to Grade 9, British Columbia teaches technological learning within applied design, skills and technologies curriculum, with Grade 8 requiring the equivalent of a full-year course that schools can deliver through modules.

Newfoundland and Labrador frames technology education as a hands-on area that can include programming and controlling physical devices through two dedicated courses about computer science in Grades 9 and 10.

Ontario’s computer studies curriculum creates dedicated course space for learning computing concepts. Ontario also illustrates how systems can shift emphasis over time: coding and digital competencies can be embedded within compulsory subjects, while a separate computer studies curriculum expands opportunities for sustained progression.

A dedicated subject provides protected classroom time to teach related core ideas (for example, data, algorithms and modelling) and to assess learning beyond using tools, while still making possible cross-curriculum learning.

It also creates clearer conditions for implementing ambitious AI literacy frameworks such as AIK12 and UNESCO’s guidance. This is because a teacher trained to translate specialized concepts for non-specialists leads instruction and can support sustained, project-based learning.

However, in many provinces, this “dedicated subject” exposure remains intermittent across K–12, often concentrated in a small number of courses, or sometimes a single year-long course with limited weekly time. This constrains cumulative progression and makes outcomes sensitive to local staffing capacity and teacher qualification.

2. Digital learning embedded in existing subjects. In New Brunswick, digital learning in Grades 6 to 8 is organized through the Middle Block, where Technology is one learning area among others. Teachers must address digital learning alongside a much wider set of practical and developmental goals, rather than teaching it as a fully separate subject with protected time.

How AI-related professional development will help teachers depends partly on learning expectations relevant to their work.

This approach can make learning more connected to real problems and other learning. But it can also limit how much time can be devoted to AI-related concepts, and whether this learning is effective, when many other objectives must be covered within the same program structure. The trade-off is generally capacity: teachers are asked to carry new conceptual content without necessarily having time, training or materials.

3. A “transversal” framework, where competencies that underpin digital technology are meant to be integrated across subjects.

For example, Manitoba teaches literacy with information communication technology (ICT) across curriculum, related to thinking critically and creatively about information and about communication, “as citizens of the global community, while using ICT safely, responsibly and ethically.” Alberta’s information and communication technology program of studies states that it is “not intended to stand alone” but should be infused within core courses.

Québec has a province-wide digital competency framework describing 12 dimensions of confident, critical and creative uses of digital technology.

When competencies related to digital learning are integrated across subjects, every student can be reached, not only those who choose electives.

However, without clear accountability tying underlying competencies to particular digital media uses, this approach can potentially yield uneven learning experiences from school to school. Every teacher must also receive sufficient professional development on the subject.

What ‘AI-ready’ could mean

Each model requires different policy supports. Dedicated subjects need staffing and teacher preparation pipelines. Embedded approaches need sustained professional learning and realistic expectations for non-specialist teachers. Transversal frameworks need clear markers for student progression and assessment strategies, otherwise implementation depends on local enthusiasm.

For many provinces, the path forward is likely not choosing one model, but combining the strengths of all three.

(Allison Shelley/The Verbatim Agency/EDUimages), CC BY-NC

This requires grounding in foundational knowledge of AI, as well as developing both discipline-specific and transdisciplinary competencies. UNESCO’s AI competency framework for teachers makes a similar point: governments should anchor AI learning in curriculum policy, build collaboratively with educators and invest in teacher preparation and resources.

Canada’s provincial diversity creates conditions for comparative analysis. If researchers study student learning associated with different models, this could help identify which policy arrangements, supports and implementation strategies are associated with stronger and more equitable forms of AI education.

Comparison may become even more salient with the OECD’s planned PISA 2029 media and artificial intelligence literacy assessment, which will be designed to examine whether students have had opportunities to learn to engage critically and responsibly with digital and AI systems.
