Heat pumps can reduce carbon emissions associated with heating buildings, and many states have set aggressive targets to increase their use in the coming decades. But while heat pumps are often cheaper choices for new buildings, getting homeowners to install them in existing homes isn’t so easy.

Current energy prices, including the rising cost of electricity, mean that homeowners may experience higher heating bills by replacing their current heating systems with heat pumps – at least in some regions of the country.

Heat pumps, which use electricity to move heat from the outside in, are used in only 14% of U.S. households. They are common primarily in warm southern states such as Florida where winter heating needs are relatively low. In the Northeast, where winters are colder and longer, only about 5% of households use a heat pump.

In our new study, my co-author Dan Schrag and I examined how heat pump adoption would change annual heating bills for the average-size household in each county across the U.S. We wanted to understand where heat pumps may already be cost-effective and where other factors may be preventing households from making the switch.

Wide variation in home heating

Across the U.S., people heat their homes with a range of fuels, mainly because of differences in climate, pricing and infrastructure. In colder regions – northern states and states across the Rocky Mountains – most people use natural gas or propane to provide reliable winter heating. In California, most households also use natural gas for heating.

In warmer, southern states, including Florida and Texas, where electricity prices are cheaper, most households use electricity for heating – either in electric furnaces, baseboard resistance heating or to run heat pumps. In the Pacific northwest, where electricity prices are low due to abundant hydropower, electricity is also a dominant heating fuel.

The type of community also affects homes’ fuel choices. Homes in cities are more likely to use natural gas relative to rural areas, where natural gas distribution networks are not as well developed. In rural areas, homes are more likely to use heating oil and propane, which can be stored on property in tanks. Oil is also more commonly used in the Northeast, where properties are older – particularly in New England, where a third of households still rely on oil for heating.

Why heat pumps?

Instead of generating heat by burning fuels such as natural gas that directly emit carbon, heat pumps use electricity to move heat from one place to another. Air-source heat pumps extract the heat of outside air, and ground-source heat pumps, sometimes called geothermal heat pumps, extract heat stored in the ground.

Heat pump efficiency depends on the local climate: A heat pump operated in Florida will provide more heat per unit of electricity used than one in colder northern states such as Minnesota or Massachusetts.

But they are highly efficient: An air-source heat pump can reduce household heating energy use by roughly 30% to 50% relative to existing fossil-based systems and up to 75% relative to inefficient electric systems such as baseboard heaters.

Heat pumps can also reduce emissions of greenhouse gases, although that depends on how their electricity is generated – whether from fossil fuels or cleaner energy, such as wind and solar.

Heat pumps can lower heating bills

We found that for households currently using oil, propane or non-heat pump forms of electric heating – such as electric furnaces or baseboard resistive heaters – installing a heat pump would reduce heating bills across all parts of the country.

The amount a household can save on energy costs with a heat pump depends on region and heating type, averaging between $200 and $500 a year for the average-size household currently using propane or oil.

However, savings can be significantly greater: We found the greatest opportunity for savings in households using inefficient forms of electric heating in northern regions. High electricity prices in the Northeast, for example, mean that heat pumps can save consumers up to $3,000 a year over what they would pay to heat with an electric furnace or to use baseboard heating.

A challenge in converting homes using natural gas

Unfortunately for the households that use natural gas in colder, northern regions – making up around half of the country’s annual heating needs – installing a heat pump could raise their annual heating bills. Our analysis shows that bills could increase by as much as $1,200 per year in northern regions, where electricity costs are as much as five times greater than natural gas per kilowatt-hour.

Even households that install ground-source heat pumps, the most efficient type of heat pump, would still see bill increases in regions with the highest electricity prices relative to natural gas.

Installation costs

In parts of the country where households would see their energy costs drop after installing a heat pump, the savings would eventually offset the upfront costs. But those costs can be significant and discourage people from buying.

On average, it costs $17,000 to install an air-source heat pump and typically at least $30,000 to install a ground-source heat pump.

Some homes may also need upgrades to their electrical systems, which can increase the total installation price even more, by tens of thousands of dollars in some cases, if costly service upgrades are required.

In places where air conditioning is typical, homes may be able to offset some costs by using heat pumps to replace their air conditioning units as well as their heating systems. For instance, a new program in California aims to encourage homeowners who are installing central air conditioning or replacing broken AC systems to get energy-efficient heat pumps that provide both heating and cooling.

Rising costs of electricity

A main finding of our analysis was that the cost of electricity is key to encouraging people to install heat pumps.

Electricity prices have risen sharply across the U.S. in recent years, driven by factors such as extreme weather, aging infrastructure and increasing demand for electric power. New data center demand has added further pressure and raised questions about who bears these costs.

Heat pump installations will also increase electricity demand on the grid: The full electrification of home heating across the country would increase peak electricity demand by about 70%. But heat pumps – when used in concert with other technologies such as hot-water storage – can provide opportunities for grid balancing and be paired with discounted or time-of-use rate structures to reduce overall operating costs. In some states, regulators have ordered utilities to discount electricity costs for homes that use heat pumps.

But ultimately, encouraging households to embrace heat pumps and broader economy-wide electrification, including electric vehicles, will require more than just technological fixes and a lot more electricity – it will require lower power prices.

Even when people’s rights are ignored, understanding the law can keep protesters engaged

There’s been a rise of know-your-rights training sessions in response to the Trump administration’s aggressive immigration enforcement tactics. This has included local public officials and organizations sharing online information over the past few months about what to do if Immigration and Customs Enforcement or other federal agents knock on your door, among other scenarios that involve immigration law enforcement.

Knowledge is power, the adage goes. But learning the letter of the law has its limits, legal rights experts have noted, if law enforcement officers do not follow the law. The Associated Press reported on Jan. 21, 2026, that ICE distributed an internal memo authorizing ICE officers to forcibly enter someone’s private home with only an administrative warrant – not one signed by a judge, as the Fourth Amendment requires.

Amy Lieberman, education editor for The Conversation U.S., spoke with Heidi Reynolds-Stenson, a scholar of social movements and protest policing, to understand the role education can play in Minnesota’s ongoing anti-ICE protests and how legal training’s limits are becoming clear.

What role is education playing in fueling Minnesota’s anti-ICE protests?

I think it is a really unique moment. There is discussion in the news nationwide about legal observing and know-your-rights training sessions. This kind of legal support and education has been part of social movements for a long time, but have never, perhaps, been in the spotlight on the level that they are right now after the January killings of ICE observers Renee Nicole Good and Alex Pretti.

A coordinated way of offering legal support to protesters grew out of 1960s and ‘70s civil rights protests. Legal support for protesters became even more organized during the student-led anti-Vietnam War movement around this same time. The first time there was an organized, mass legal defense of protesters was for the Stop the Draft Week in 1967, when a group of lawyers and law students began working in coordination with activists.

Since then, community organizers, lawyers, law students and others have developed strategies for offering legal support to protesters. That includes legal observers. Legal observers can be lawyers, law students or others trained not to protest, but to independently observe, take notes on and photograph or video incidents at protests, like law enforcement arresting or assaulting someone.

We see, over time, that the way people organize and offer legal support to protesters has become more and more sophisticated. More and more people have knowledge about their civic and legal rights. Other forms of legal support, such as jail and court solidarity, in which individual people who are arrested make collective decisions to support one another, have become more common.

Now, people are also learning about more than their First Amendment rights – they are learning about the rights of immigrants and of anyone who is interacting with ICE and Border Patrol officers. That intensifies the complexity of what people need to know.

Altogether, there is a complex system of legal support in place that has been shown to be very effective at preventing activists from disengaging after experiences of state repression.

What does your own research show regarding how education can shape protests?

In my own research, when activists had experiences of repression – when they were arrested at protests, as has happened in Minneapolis, or experienced police violence, like being sprayed with chemical irritants – legal education was a major determining factor on whether they continued to be involved in the protest movement.

Another deciding issue was whether or not protesters were being helped by pro bono lawyers or there were legal observers present to make protesters feel more confident going into a certain situation.

As people become more educated about their rights and more prepared for the potential risks of protesting, that can make them more confident about going to a protest in the first place and more likely to continue in that work.

We know that, in reality, the rights people learn about are not always respected, at protests or in other situations. So, it is one thing to say that you have a right to do something, like to protest, or not let ICE or Border Patrol agents into your home without a judicial warrant.

It is another thing in practice, especially in the current moment that we are in, in which immigration enforcement officers have increasingly shown disregard for people’s rights. But it is still important for people to be aware that those rights exist.

What role do legal observers play in influencing protest movements?

Legal observers can play a critical role in collecting independent, neutral information about law enforcement actions at protests that can be used if there is a civil suit or a criminal case coming out of a protest.

Legal observing can also, in theory, deter officers who are policing protests, since they know they are being watched and data is being collected on their actions, including potential rights violations.

How can education serve as a means of self-defense at protests?

Education is the most powerful weapon for people involved in protest movements – that is, knowledge and understanding of what their rights are as well as the risks. Equally important is collecting bail fund money before someone is actually arrested, having a network of people ready to do the work after a protest to defend arrested activists, and holding law enforcement officers accountable for violating people’s rights. Protesters or observers can then know that if they are arrested or injured by law enforcement officers, that people are already there ready to help them.

In my view, the level of disrespect that federal immigration officers are currently showing to people exercising their rights to protest and to film and otherwise monitor public officials is unprecedented. But it has always been the case that just because a legal right exists, it does not mean that it is followed by law enforcement or the government more broadly. Then, and now, it has always been organized groups of individuals who make those rights real through exercising them and working to hold those accountable who violate them.

America is falling behind in the global EV race – that’s going to cost the US auto industry

Source: The Conversation – USA (2) – By Hengrui Liu, Postdoctoral Scholar in Economics and Public Policy, The Fletcher School, Tufts University

At the 2026 Detroit Auto Show, the spotlight quietly shifted. Electric vehicles, once framed as the inevitable future of the industry, were no longer the centerpiece. Instead, automakers emphasized hybrids, updated gasoline models and incremental efficiency improvements.

The show, held in January, reflected an industry recalibration happening in real time: Ford and General Motors had recently announced US$19.5 billion and $6 billion in EV-related write-downs, respectively, reflecting the losses they expect as they unwind or delay parts of their electric vehicle plans.

The message from Detroit was unmistakable: The United States is pulling back from a transition that much of the world is accelerating.

Highlights from the Detroit Auto Show, starting with V-8 trucks, by the Detroit Free Press’ auto writer.

That retreat carries consequences far beyond showroom floors.

In China, Europe and a growing number of emerging markets, including Vietnam and Indonesia, electric vehicles now make up a higher share of new passenger vehicle sales than in the United States.

That means the U.S. pullback on EV production is not simply a climate problem – gasoline-powered vehicles are a major contributor to climate change – it is also an industrial competitiveness problem, with direct implications for the future of U.S. automakers, suppliers and autoworkers. Slower EV production and slower adoption in the U.S. can keep prices higher, delay improvements in batteries and software, and increase the risk that the next generation of automotive value creation will happen elsewhere.

Where EVs are taking over

In 2025, global EV registrations rose 20% to 20.7 million. Analysts with Benchmark Mineral Intelligence reported that China reached 12.9 million EV registrations, up 17% from the previous year; Europe recorded 4.3 million, up 33%; and the rest of the world added 1.7 million, up 48%.

By contrast, U.S. EV sales growth was essentially flat in 2025, at about 1%. U.S. automaker Tesla experienced declines in both scale and profitability – its vehicle deliveries fell 9% compared to 2024, the company’s net profit was down 46%, and CEO Elon Musk said it would put more of its focus on artificial intelligence and robotics.

Market share tells a similar story and also challenges the assumption that vehicle electrification would take time to expand from wealthy countries to emerging markets.

In 39 countries, EVs now exceed 10% of new car sales, including in Vietnam, Thailand and Indonesia, which reached 38%, 21% and 15%, respectively, in 2025, energy analysts at Ember report.

In the U.S., EVs accounted for less than 10% of new vehicle sales, by Ember’s estimates.

U.S. President Donald Trump came back into office in 2025 promising to end policies that supported EV production and sales and boost fossil fuels. But while the U.S. was curtailing federal consumer incentives, governments elsewhere largely continued a transition to electric vehicles.

Europe softened its goal for all vehicles to have zero emissions by 2035 at the urging of automakers, but its new target is still a 90% cut in automobiles’ carbon dioxide emissions by 2035.

Germany launched a program offering subsidies worth 1,500 to 6,000 euros per electric vehicle, aimed at small- and medium-income households.

In developing economies, EV policy has largely been sustained through industrial policies. In Brazil, the MOVER program offers tax credits explicitly linked to domestic EV production, research and development, and efficiency targets. South Africa is introducing a 150% investment allowance for EV and battery manufacturing, giving them a tax break starting in March 2026. Thailand has implemented subsidies and reduced excise tax tied to mandatory local production and export commitments.

In China, the EV industry has entered a phase of regulatory maturity. After a decade of subsidies and state-led investment that helped domestic firms undercut global competitors, the government’s focus is no longer on explosive growth at home.

With their domestic market saturated and competition fierce, Chinese automakers are pushing aggressively into global markets. Beijing has reinforced this shift by ending its full tax exemption for EV purchases and replacing it with a tapered 5% tax on EV buyers.

Consequences for US automakers

EV manufacturing is governed by steep learning curves and scale economies, meaning the more vehicles a company builds, the better it gets at making them faster and cheaper. Low domestic production and sales can mean higher costs for parts and weaker bargaining power for automakers in global supply chains.

The competitive landscape is already changing. In 2025, China exported 2.65 million EVs, doubling its 2024 exports, according to the China Association of Automobile Manufacturers. And BYD surpassed Tesla as the world’s largest EV maker in 2025.

The U.S. risks becoming a follower in the industry it once defined.

Some people argue that American consumers simply prefer trucks and hybrids. Others point to Chinese subsidies and overcapacity as distortions that justify U.S. industry caution. These concerns deserve consideration, but they do not outweigh the fundamental fact that, globally, the EV share of auto sales continues to rise.

What can the US do?

For U.S. automakers and workers to compete in this market, the government, in our view, will have to stop treating EVs as an ideological matter and start governing it like an industrial transition.

That starts with restoring regulatory credibility, something that seems unlikely right now as the Trump administration moves to roll back vehicle emissions standards. Performance standards are the quiet engine of industrial investment. When standards are predictable and enforced, manufacturers can plan, suppliers can invest in new businesses, and workers can train for reliable demand.

Governments at state and local levels and industry can also take important steps.

Focus on affordability and equity: The federal clean-vehicle tax credit that effectively gave EV buyers a discount expired in September 2025. An alternative is targeted, point-of-sale support for lower- and middle-income buyers. By moving away from blanket credits in favor of targeted incentives – a model already used in California and Pennsylvania – governments can ensure public funds are directed toward people who are currently priced out of the EV market. Additionally, interest-rate buydowns that allow buyers to reduce their loan payments and “green loan” programs can help, typically funded through state and local governments, utility companies or federal grants.

Keep building out the charging network: A federal judge ruled on Jan. 23, 2026, that the Trump administration violated the law when it suspended a $5 billion program for expanding the nation’s EV charger network. That expansion effort can be improved by shifting the focus from the number of ports installed to the number of working chargers, as California did in 2025. Enforcing reliability and clearing bottlenecks, such as electricity connections and payment systems, could help boost the number of functioning sites.

Use fleet procurement as a stabilizer for U.S. sales: When states, cities and companies provide a predictable volume of vehicle purchases, that helps manufacturers plan future investments. For example, Amazon’s 2019 order of 100,000 Rivian electric delivery vehicles to be delivered over the following decade gave the startup automaker the boost it needed.

Treat workforce transition as core infrastructure: This means giving workers skills they can carry from job to job, helping suppliers retool instead of shutting down, and coordinating training with employers’ needs. Done right, these investments turn economic change into a source of stable jobs and broad public support. Done poorly, they risk a political backlash.

The scene at the Detroit Auto Show should be a warning, not a verdict. The global auto industry is accelerating its EV transition. The question for the United States is whether it will shape that future – and ensure the technologies and jobs of the next automotive era are in the U.S. – or import it.

Rescheduling marijuana would be a big tax break for legal cannabis businesses – and a quiet form of deregulation

Source: The Conversation – USA (2) – By Sloan Speck, Associate Professor of Law, University of Colorado Boulder

In December 2025, the Trump administration accelerated the process of reclassifying marijuana from Schedule I to Schedule III under the Controlled Substances Act – a shift that would reduce restrictions and penalties associated with the drug.

Under the move, medical and recreational marijuana would still remain illegal at the federal level. At the state level, medical use is currently legal in 40 states and the District of Columbia, and recreational use is permitted in 24 states and Washington, D.C. While the administration touted the medical research benefits of rescheduling, the medical and recreational marijuana industry lauded it for an entirely different reason: income tax savings.

Indeed, one of rescheduling’s most significant – and most immediate – effects would be tax relief for all legal marijuana businesses in the states that host them.

But business taxes do more than raise revenue – they also create incentives that shape how companies organize and operate. For legal marijuana businesses – both medical and recreational dispensaries alike – rescheduling marijuana would relax these implicit restrictions, serving as a quiet form of deregulation that removes tax pressures that currently shape the industry’s financing, structure and compliance. From this perspective, rescheduling would cut taxes but also remove one of the federal government’s levers over an industry principally regulated by the states.

I study how tax rules shape what businesses do and the social effects of changing those rules. In my view, the tax implications of rescheduling marijuana alone are likely to have consequences that go far beyond the tax bill that businesses pay.

Why marijuana businesses are taxed differently

Under federal law, state-legal marijuana businesses face unique tax burdens.

Most businesses can deduct, or write off, ordinary and necessary expenses. For example, businesses generally can subtract the costs of rent and utilities from the income they earn. But that’s not the case for businesses that deal in Schedule I and II controlled substances, including marijuana.

In effect, legal marijuana businesses pay federal income tax on their gross income rather than their net income like other companies.

Imagine a business with US$100,000 of income before expenses and $80,000 of otherwise deductible expenses. Ordinarily, the business would pay $4,200 in tax on $20,000 of net income, assuming a 21% tax rate. The business’s cash profits would be $15,800 for the year – a healthy net profit margin.

If this hypothetical business legally sold marijuana, Section 280E of the Internal Revenue Code would deny any income tax deductions for the business’s $80,000 in expenses. This rule applies even though the business’s expenses are real costs, and even though the business is legal under state law. In this scenario, the business would owe $21,000 in tax on $100,000 of gross income. This would put the business in the red for the year, with a negative cash flow of $1,000 and a negative net profit margin.

For many legal marijuana businesses, making the math work isn’t a hypothetical challenge. Indeed, some enterprises have reported real-world effective tax rates as high as 80%more than twice the top statutory rate for individuals.

This state of affairs traces to two court decisions handed down more than five decades apart. In 1927, the Supreme Court held that income from illegal activities remained subject to tax – a decision later leveraged in mob boss Al Capone’s 1931 conviction on criminal tax evasion charges. Then, in 1981, the U.S. Tax Court affirmed that illegal activities were taxable on their net income after deductions, like legal businesses. Lawmakers objected, and Congress enacted Section 280E the following year in response.

Essentially, the move gave drug traffickers a Hobson’s choice: face civil or criminal penalties for failing to properly report their income, or pay punishingly high effective tax rates. Just as Treasury Department enforcers used tax law to combat organized crime during Prohibition, tax law’s dual disincentives expressly discouraged illicit drug sales.

Because Section 280E applies only to Schedule I and II substances, rescheduling to Schedule III would tax legal marijuana businesses like other businesses. According to advocates, this would better align federal tax law with widespread state-level legalization of marijuana. In effect, rescheduling could equate to a tax break of around $2.3 billion dollars for the marijuana industry, according to one estimate.

How the tax code quietly regulates marijuana

Despite these high effective tax rates, the state-legal marijuana industry has more than tripled in revenue over the past decade and supports more than 400,000 jobs. Tax law, however, has shaped how this industry operates.

In this way, tax law serves as a form of quiet regulation – not directly, by setting licensing standards or policing potency, but indirectly. If marijuana were rescheduled, the federal government would give up this mechanism for indirect regulation.

As it currently stands, Section 280E has three important regulatory effects:

First, Section 280E limits businesses’ financing options. Like other enterprises, legal marijuana businesses need capital to grow. By constraining after-tax profits and cash flow, the status quo makes it harder for these marijuana businesses to finance growth internally using their own money from operations, known as “retained earnings.” This tax-induced capital scarcity may help explain mature legal marijuana industries’ relatively low rates of year-over-year growth. After taxes, there’s simply very little cash to reinvest.

This constraint pushes legal marijuana businesses to finance growth through external – and often unconventional – funding sources. Because marijuana businesses remain illegal under federal law, commercial banks and public capital markets may treat otherwise legal businesses as off-limits or high-risk. These businesses often turn to private capital for loans, specialized leasing arrangements and equity investments. Given the federal restrictions on marijuana, private investors tend to scrutinize these transactions closely, often insisting on protective covenants and operational restrictions.

Second, Section 280E encourages legal marijuana businesses to isolate activities that “don’t touch the plant” from marijuana production and sales. If the nonmarijuana activities are truly separate – legally, spatially and operationally – they may be able to claim business expense deductions that direct marijuana-related activities cannot.

Legal marijuana businesses have implemented these separate structures for activities from back-office support and real estate management to licensing for branding and merchandise. In addition to affecting tax burdens, these structures require ongoing operational oversight by outside parties – lawyers, accountants and other providers – and enforce the siloing of marijuana-touching activities away from other activities.

Finally, Section 280E raises the stakes of accurately accounting for the marijuana sold by these businesses. Courts have affirmed that legal marijuana businesses can reduce their gross income by the “cost of goods sold” – the direct production and acquisition costs of inventory. Even under Section 280E, these businesses can subtract the costs to grow, process and package marijuana from their sales revenue. As a result, these businesses meticulously monitor direct production costs throughout their supply chains.

This supply chain management offers another pathway for indirect regulation. Many state regulatory regimes already require inventory tracking. But Section 280E adds a financial reward for rigorous documentation, controls and auditing. Although some of this tax compliance work is mere paper-shuffling, public policy may favor multiple forms of regulation by multiple stakeholders – a diversity of oversight for an industry where lapses or inconsistencies can have serious social costs.

Federal tax rules for state-legal marijuana businesses operate as a form of indirect, or quiet, regulation: a national overlay that complements – and amplifies – state regulatory regimes. Rescheduling would remove this federal overlay by taking marijuana out of Section 280E’s reach.

From this perspective, the debate over rescheduling is about more than just tax normalization versus public health risks. Rescheduling raises bigger questions of institutional design: whether the federal government should yield one of its most practical points of leverage over the legal marijuana industry – and, if so, whether another regulatory mechanism should replace it.

A growing nursing shortage is made worse by nurses’ daily challenges of patients and their families rolling their eyes, yelling and striking

Source: The Conversation – USA (3) – By Carolyn Dickens, Nurse practitioner and Associate Dean, University of Illinois Chicago

A 2024 report found that 4 out of 5 nurses experienced at least one episode of such behaviors in the previous year. Ivan-balvan/iStock via Getty Images Plus

Imagine being a dentist, and your clients roll their eyes at you, comment that you don’t know what you’re doing – or even spit at you.

Unimaginable, right? But that’s what nurses experience when patients or their families do the eye roll or hit, bite or spit at them. What’s more, a bedside nurse may repeatedly endure bad behavior from a patient or their loved ones for a shift of eight to 12 hours.

Workplace violence is frequently underreported, in part because many nurses see it as being part of their job.

Nurses experience violence and incivility due to a combination of factors, such as working in high-risk clinical environments like the emergency department, or dealing with patient-related challenges such as altered mental status. As a result, nursing is the health profession most likely to experience workplace violence, incivility or threat of violence. This includes physical violence, harassment, intimidation or other types of disruptive behavior.

A 2024 report found that more than 80% of registered nurses said they had experienced at least one instance of workplace violence in the previous year; 68% said they were verbally threatened. The vast majority of the workplace violence stemmed from patients or family members of the patient.

Workplace violence and harassment are major contributors to a growing shortfall in the nursing workforce.

An exodus from nursing

As a nurse practitioner, I work closely with nurses and interact with patients and their families on a regular basis. A nurse practitioner – which is a registered nurse but with advanced training and a wider scope of treatment – typically doesn’t have as much direct interaction with patients and their families due to the difference in their job responsibilities compared with nurses.

However, I also experience incivility from patients and families when I can’t give them the answers they expect to hear, or when I’m late because the time I spent with the previous patient took longer than expected.

I recognize that much of their anger and impoliteness stems from fear and frustration. I also understand the difficulty in dealing with a health care system that’s bureaucratic and under-resourced. But my understanding why they feel this way does not make the behavior OK.

Workplace violence directed toward nurses has been studied for well over a decade. But the widespread prevalence of incivility remains poorly understood, in part because nurses are reluctant to report it. A 2022 survey of nurses across all care settings found that 60% had experienced bulling and incivility and nearly a third had experienced an incident of violence. Nearly half reported that they planned on or were considering leaving patient care in the next six months. And a significant number said that instituting a non-bullying program or no-tolerance policy toward violence would greatly improve their work satisfaction.

The feeling that they aren’t supported is another reason why nurses are increasingly likely to leave the profession, with 31% stating in the same survey that it would help their work satisfaction if their organization would listen to them.

This is unsustainable for a number of reasons, one being the growing shortage of nurses in the U.S.. The shortfall has gotten worse since the COVID-19 pandemic, with more and more nurses leaving due to burnout.

More nurses are needed to care for the aging population in the U.S., but fewer nurses are replacing the retiring ones. Over the next decade, the U.S. is projected a shortage of more than 63,000 registered nurses to care for its aging population.

Starting from the ground up

The idealized concept of the “good nurse” is that of an unfailingly polite caregiver, always accommodating and emotionally composed. This makes it difficult for nurses to set boundaries or object to rudeness.

No one-size-fits-all solution will address the incivility problem, although health care systems have tried. Some hospitals, for example, post signs in patient rooms and elevators with messages like: “This is a place of health and healing – please respect everyone.” And many health care organizations have behavioral emergency response teams – typically social workers and security personnel – to intervene when tensions escalate. Although such response teams are considered best practice, few hospitals and other health care organizations have them.

Other organizational efforts, such as resilience training and wellness lectures, are well-intended and in good faith, but they also reinforce the harmful notion that incivility is inevitable and must be endured, not addressed. Worse, they give the appearance that health care organizations are taking action. Instead, they place the burden of coping squarely on nurses, who are often unable to attend the lectures due to time constraints.

A way forward

There are some actions that health organizations can take to address the incivility directed toward nurses from families. For example, setting realistic expectations for patients and their families would decrease the frustration and change this destructive dynamic. Transparency is critical. For instance, if emergency room waiting areas have a screen showing the wait time – even if it’s 12 hours – it would cut down on a great deal of anxiety for patients and their families that can escalate into anger, disrespect and violence.

And when patients must spend the night in the hospital, it would help for families to be told what time the health care provider makes their rounds so that loved ones are not needlessly waiting around for hours.

Families also deserve to know if the hospital is understaffed, with perhaps only one nurse managing multiple patients. This could help loved ones be more understanding of a slower response to a call light.

These types of interventions could be delivered through educational videos with QR codes and placed in each patient room.

The nursing profession has a conflicting identity, and it’s one where some patients translate a nurse’s compassion and caring into a signal to disregard basic human boundaries. Only through organizational and societal shifts – beginning with employers – can change occur and incivility toward nurses become infrequent, rather than the norm.

Everyone can help address this problem, whether you or your loved one is hospitalized, by being understanding and respectful to others, especially when interacting with nurses.

Artemis II: The first human mission to the moon in 54 years launches soon — with a Canadian on board

It’s been 54 years since the last Apollo mission, and since then, humans have not ventured beyond low-Earth orbit. But that’s all about to change with next week’s launch of the Artemis II mission from the Kennedy Space Center in Florida.

This is the first crewed flight of NASA’s Artemis program and the first time since 1972 that humans have ventured to the moon. Onboard is Canadian astronaut Jeremy Hansen, who will be the first non-American to fly to the moon and will make Canada only the second country in the world to send an astronaut into deep space.

I am a professor, an explorer and a planetary geologist. For the past 15 years, I have been helping to train Hansen and other astronauts in geology and planetary science. I am also a member of the Artemis III Science Team and the principal investigator for Canada’s first ever rover mission to the moon.

What will the mission achieve?

NASA’s Artemis program, launched in 2017, has the ambitious goal to return humans to the moon and to establish a lunar base in preparation for sending humans to Mars. The first mission, Artemis I, launched in late 2022. Following some delays, Artemis II is scheduled for launch as early as a week from now.

Onboard will be Hansen, along with his three American crew-mates.

This is an incredibly exciting mission. Artemis II is the first time humans have launched on NASA’s huge SLS (Space Launch System) rocket, and the first time humans have flown in the Orion spacecraft.

SLS is the most powerful rocket NASA has ever built, with the capability to send more than 27 metric tonnes of payload — equipment, instruments, scientific experiments and cargo — to the moon. The Orion spacecraft sits at the very top and is the crew’s ride to the moon. The Artemis II crew named their Orion capsule Integrity, a word they say embodies trust, respect, candour and humility.

What will Artemis II crew do in space?

Following launch, the crew will carry out tests of Integrity’s essential life-support systems: the water dispenser, firefighting equipment, and, of course, the toilet. Did you know there was no toilet on the Apollo missions? Instead, the crews used “relief tubes.”

If everything looks good, the Artemis II will ignite what’s known as the Interim Cryogenic Propulsion Stage — part of the SLS rocket still connected to Integrity — to elevate the spacecraft’s orbit. If things are still looking good, the Orion spacecraft and its four human travellers will spend 24 hours in a high-Earth orbit up to 70,000 kilometres away from the planet.

For comparison, the International Space Station orbits the Earth at a mere 400 kilometres.

Following a series of tests and checks, the crew will conduct one of the most critical stages of the mission: the Trans-Lunar Injection, or TLI. This is the crucial moment that changes a spacecraft from orbiting the Earth — where the option to quickly return home remains — to sending it on its way to the moon and into deep space.

Once the Integrity is on its way to the moon after TLI, there is no turning back — at least, not without going to the moon first. That’s because Artemis II — like the early Apollo missions — enters what’s called a “free-return trajectory” after the TLI. What this means is that even if Integrity’s engines fail completely, the moon’s gravity will naturally loop the spacecraft around it and aim it towards Earth.

After the three-day journey to the moon, the crew will carry out perhaps the most exciting stage of the mission: lunar fly-by. Integrity will loop around the far side of the moon, passing anywhere from 6,000 to 10,000 kilometres above its surface — much farther than any Apollo mission.

To quote Star Trek, at that most distant point, the Artemis II crew will have boldly gone where no (hu)man has gone before. This will be, quite literally, the farthest from Earth that any human being has ever travelled.

International effort to explore the moon

That a Canadian astronaut is part of the crew of Artemis II is a testament to the collaborative international nature of the Artemis program.

While NASA created the program and is the driving force, there are now 60 countries that have signed the Artemis Accords.

The foundation for the Artemis Accords is the recognition that international co-operation in space is intended not only to bolster space exploration but to enhance peaceful relationships among nations. This is particularly necessary now — perhaps more than any other time since the Cold War.

I truly hope that as Integrity returns from the moon’s far side, people around the world will pause — at least for a few moments — and be united in thinking of a better future. As American astronaut Bill Anders, who flew the first crewed Apollo mission to the moon, once said:

“We came all this way to explore the moon, and the most important thing is that we discovered the Earth.”

Quand et comment décide-t-on qu’une espèce est éteinte ?

Source: The Conversation – France (in French) – By Violaine Nicolas Colin, Maitre de conférence en systématique et phylogéographie, Muséum national d’histoire naturelle (MNHN)

Il est bien plus difficile de prouver une absence que de constater une présence. Il faut donc souvent des années, et un processus minutieux, pour qu’une espèce soit déclarée éteinte. Cela peut-être particulièrement difficile lorsqu’il s’agit d’espèces nocturnes, discrètes ou vivant dans des milieux reculés.


Déclarer une espèce « éteinte », ce n’est pas comme rayer un nom d’une liste. C’est un verdict lourd de sens, prononcé avec une extrême prudence. Car annoncer trop tôt une disparition peut condamner une espèce qui existe peut-être encore quelque part. Alors comment font les scientifiques en pratique ?

Comment les scientifiques tranchent-ils la question de l’extinction ?

Pour en arriver là, les biologistes doivent mener des recherches exhaustives, dans tous les habitats potentiels, aux bonnes périodes (saisons, cycles de reproduction), et sur une durée adaptée à la biologie de l’espèce.

Concrètement, plusieurs indices sont analysés ensemble :

  • l’absence prolongée d’observations fiables,

  • des campagnes de recherche répétées et infructueuses,

  • le temps écoulé depuis la dernière observation confirmée,

  • et l’état de l’habitat. Si celui-ci a été totalement détruit ou transformé au point d’être incompatible avec la survie de l’espèce, la conclusion devient plus solide.

Autrement dit, on ne déclare pas une espèce éteinte parce qu’on ne l’a pas vue depuis longtemps, mais parce qu’on a tout fait pour la retrouver, sans succès.

Qui décide officiellement de l’extinction ?

À l’échelle mondiale, c’est l’Union internationale pour la conservation de la nature (UICN) qui statue, depuis 1964, via sa célèbre « liste rouge », référence internationale en matière de biodiversité.

La liste rouge classe les espèces selon leur risque d’extinction, en plusieurs catégories allant de « préoccupation mineure » à « éteinte ». Elle est mise à jour régulièrement, accessible en ligne, et donne aujourd’hui le statut de 172 600 espèces.

Bien plus qu’une simple liste d’espèces et de leur statut, elle fournit aussi des informations sur l’aire de répartition, la taille des populations, l’habitat et l’écologie, l’utilisation et/ou le commerce, les menaces ainsi que les mesures de conservation qui aident à éclairer les décisions nécessaires en matière de préservation.

C’est donc un outil indispensable pour informer et stimuler l’action en faveur de la conservation de la biodiversité et des changements de politique. Le processus d’élaboration de la liste rouge implique le personnel de l’équipe d’évaluation et de connaissance de la biodiversité de l’UICN, les organisations partenaires, les scientifiques, les experts de la Commission de la sauvegarde des espèces de l’UICN, ainsi que les réseaux partenaires qui compilent les informations sur les espèces.

L’IUCN déclare une espèce comme « éteinte » quand il n’existe aucun doute raisonnable que le dernier individu a disparu. Des gouvernements ou agences nationales peuvent également déclarer une espèce éteinte localement, sur leur territoire.

Des extinctions bien réelles : quelques exemples récents

Le dodo (Raphus cucullatus) reste l’icône des extinctions causées par l’humain : découvert à la fin du XVIᵉ siècle lors de l’arrivée des Européens sur l’île Maurice, il disparaît moins de cent ans plus tard, victime de la chasse et des espèces introduites.

Mais il est loin d’être un cas isolé, les extinctions récentes touchent tous les groupes du vivant. Si les espèces insulaires représentent une part disproportionnée des extinctions récentes (les îles, bien qu’elles ne couvrent que 5 % des terres émergées, abritent près de 40 % des espèces menacées), les espèces continentales sont également touchées.

  • L’espadon de Chine (Psephurus gladius), une grande espèce de poisson d’eau douce (jusqu’à plusieurs mètres) qui vivait dans le fleuve Yangtsé, a été déclaré éteint en 2022. La surpêche, les barrages bloquant les migrations et la destruction de son habitat ont eu raison de cette espèce spectaculaire qui a été aperçue pour la dernière fois en 2003.

  • Le courlis à bec grêle (Numenius tenuirostris), un oiseau des zones humides, qui hibernait autour de la Méditerranée avant de rejoindre sa Sibérie natale au printemps, n’a plus été observé de manière certaine depuis 1995. Une étude publiée fin 2024 estime à 96 % la probabilité qu’il soit aujourd’hui éteint, victime de l’agriculture intensive et du drainage des marais.

  • La musaraigne de l’île Christmas (Crocidura trichura), discrète habitante de l’océan Indien, a été officiellement déclarée éteinte en 2025, après quarante ans sans observation malgré des recherches répétées. Les prédateurs introduits (rats, chats) et les perturbations de l’habitat sont les principaux suspects.

  • Deux escargots polynésiens (Partula dentifera et P. pearcekellyi) ont été officiellement déclarés éteints en 2024. La cause principale de leur disparition serait l’introduction d’un escargot prédateur invasif (Euglandina rosea), une tragédie silencieuse mais fréquente sur les îles.

  • Chez les plantes, Amaranthus brownii, une plante herbacée annuelle endémique d’une petite île hawaïenne, a été déclarée éteinte en 2018 après plus de trente-cinq ans sans observation malgré des recherches intensives. La destruction de son habitat et l’arrivée d’espèces invasives ont conduit à sa disparition, sans qu’aucune graine ni plant viable n’ait pu être conservé.

  • Depuis 2024, la liste rouge de l’IUCN comprend aussi des champignons. En mars 2025 la liste évaluait le statut de 1 300 espèces de champignons. Nous sommes loin des 155 000 espèces connues, mais les premières évaluations restent préoccupantes avec 411 espèces de champignons menacées d’extinction, soit près d’un tiers des espèces recensées.

Peut-on vraiment être sûr ? Entre erreurs, miracles et illusions

L’histoire de la biodiversité peut être pleine de rebondissements.

  • L’effet Lazare désigne la redécouverte d’espèces que l’on croyait éteintes. Ce terme fait référence au personnage biblique du Nouveau Testament ressuscité plusieurs jours après sa mort par Jésus. Ce terme est aussi employé en paléontologie pour désigner des groupes d’organismes qui semblent avoir disparu pendant des millions d’années dans le registre fossile avant de réapparaître comme par miracle.

Selon le naturaliste, Brett Scheffers et ses collaborateurs au moins 351 espèces ont ainsi été « ressuscitées » en un peu plus d’un siècle, parfois après des décennies d’absence. La perruche nocturne (Pezoporus occidentalis) ou la rousserolle à grand bec (Acrocephalus orinus) en sont des exemples spectaculaires. Il est important de noter que la majorité de ces redécouvertes concerne des espèces si rares ou difficiles à trouver que leur seule occurrence confirmée provenait de leur description initiale. Ces espèces redécouvertes sont donc pour leur grande majorité toujours considérées comme gravement menacées et pourraient disparaître prochainement.

  • L’effet Roméo, au contraire, survient lorsqu’on renonce trop tôt à sauver une espèce en la croyant disparue.
Conuropsis carolinensis. Dessins d’Audubon.
Domaine public

Résultat : on cesse les efforts de conservation… alors qu’il restait peut-être une chance de la sauver. Ce nom fait référence au Roméo de Shakespeare qui renonce à vivre en croyant Juliette morte, alors qu’elle ne l’est pas encore. La conure de Caroline (Conuropsis carolinensis), un perroquet d’Amérique du Nord, pourrait en être un triste exemple. Présumée éteinte au début du XXᵉ siècle cette espèce a probablement survécu plus longtemps comme en atteste les nombreux témoignages locaux (incluant des détails sur son comportement) jusqu’aux années 1950, et peut-être même jusqu’aux années 1960.

  • Enfin, l’effet thylacine (du nom du thylacine, plus connu sous le nom de « tigre de Tasmanie ») illustre l’excès inverse : l’espoir persistant qu’une espèce éteinte survit encore, malgré l’absence de preuves solides.

Domaine

Le thylacine, dont le dernier animal (captif) est officiellement mort en 1936, continue de fait d’alimenter de nombreuses rumeurs et témoignages d’observations non vérifiables. Selon l’étude scientifique la plus complète à ce sujet le dernier animal sauvage entièrement documenté (avec des photographies) a été abattu en 1930, mais il n’y aurait aucune raison de douter de l’authenticité de deux carcasses signalées en 1933, ni de deux autres captures suivies de relâchers en 1935 et en 1937. Par la suite, sur une période de huit décennies, 26 morts et 16 captures supplémentaires ont été rapportées, mais sans être vérifiées, ainsi que 271 observations par des « experts » (anciens piégeurs, chasseurs, scientifiques ou responsables) et 698 signalements par le grand public. En 2005, le magazine australien d’information The Bulletin a offert une récompense de plus d’un million de dollars (soit plus 836 000 euros) à quiconque fournirait une preuve scientifique de l’existence du thylacine, en vain. Entre 2014 et 2020, 3 225 sites équipés de pièges photographiques en Tasmanie, totalisant plus de 315 000 nuits de surveillance, n’ont révélé aucune détection pouvant être attribuée à un thylacine.

Pourquoi est-ce si compliqué de mesurer les extinctions ?

Prouver une absence est bien plus compliqué que constater une présence. L’UICN préfère donc l’extrême prudence et ne classe une espèce « éteinte » que lorsqu’elle peut l’affirmer avec certitude. En effet, comme nous l’avons vu, officialiser une extinction est un acte lourd de conséquences car cela conduit à clôturer les éventuelles mesures de protection. Ainsi, le requin perdu (Carcharhinus obsoletus) est estimé comme « gravement menacé d’extinction – possiblement éteint » par la dernière publication de la liste rouge de l’UICN en 2020, alors qu’il n’a plus été vu dans ses eaux de la mer de Chine depuis 1934. La liste rouge ne déclarant éteintes que des espèces pour lesquelles il n’y a aucun doute, les extinctions enregistrées sont largement sous-estimées.

De plus, notre vision est biaisée : les vertébrés (en particulier les oiseaux et les mammifères) sont relativement bien suivis, mais l’immense majorité des espèces – insectes, invertébrés, champignons, microorganismes – restent très mal connues et leur taux d’extinction est sous-estimé. Beaucoup d’espèces sont discrètes, minuscules, nocturnes ou vivent dans des milieux difficiles d’accès. Pour la majorité d’entre elles, les données sont quasi inexistantes et elles peuvent disparaître sans que personne ne s’en aperçoive.

Pourquoi est-ce si important de savoir ?

Savoir si une espèce a réellement disparu permet de choisir les bonnes stratégies de conservation. Beaucoup d’espèces peuvent encore être sauvées lorsque quelques individus subsistent. C’est par exemple le cas du condor de Californie (Gymnogyps californianus) pour lequel il restait seulement 22 individus à l’état sauvage dans les années 1980. Un programme de capture de ces spécimens, puis d’élevage en captivité et de réintroduction progressive a permis à la population sauvage de réaugmenter progressivement et d’atteindre 369 individus en 2024.

À l’inverse, un diagnostic erroné – trop optimiste ou trop pessimiste – peut détourner les efforts au mauvais moment.

L’extinction est un fait biologique, mais c’est aussi un défi méthodologique. Entre prudence scientifique, incertitudes du terrain et illusions collectives, établir la frontière entre « menacée » et « éteinte » reste l’un des exercices les plus sensibles de la conservation moderne.

Une ambition monumentale… Pourquoi Donald Trump veut-il créer à Washington une copie de l’Arc de triomphe ?

Source: The Conversation – in French – By Garritt C. Van Dyk, Senior Lecturer in History, University of Waikato

Copie assumée de l’Arc de triomphe parisien, l’« Independence Arch », déjà surnommé « Arc de Trump », s’inscrit dans une longue tradition monumentale, entre célébration du pouvoir, réécriture du passé et affirmation politique.


Donald Trump a pris le temps cette semaine, alors que l’actualité internationale et américaine était particulièrement chargée, de présenter trois nouvelles propositions architecturales pour son projet d’« Independence Arch » à Washington. Les trois rendus rappellent clairement l’Arc de triomphe de la place de l’Étoile à Paris, même si l’un d’eux se distingue par des ornements dorés, dans la lignée des choix décoratifs de Trump pour le Bureau ovale de la Maison-Blanche.

Commandée en vue du 250ᵉ anniversaire de la signature de la Déclaration d’indépendance des États-Unis, le 4 juillet, cet arc de triomphe s’inscrit dans une longue tradition de monuments célébrant les victoires militaires, des empereurs romains à Napoléon Bonaparte.

Ce projet de monument participe ainsi pleinement de la politique étrangère de Donald Trump et de l’ambition qu’affiche ce dernier de voir les États-Unis étendre leur contrôle sur l’« hémisphère occidental » – une orientation que le président a lui-même baptisée la « doctrine Donroe ».

Mais une question demeure, largement posée : alors que le projet copie l’Arc de triomphe, monument emblématique s’il en est, un hommage personnel est-il vraiment la manière la plus pertinente de marquer l’anniversaire de la rupture des États-Unis avec le pouvoir absolu et la monarchie britannique ?

L’« Arc de Trump »

Lorsque Donald Trump a présenté pour la première fois, en octobre 2025, des maquettes de l’arche envisagée, un journaliste lui a demandé à qui elle était destinée. Trump a répondu : « À moi. Ce sera magnifique. » Dans une déclaration faite en décembre, le président a affirmé que la nouvelle arche « sera comme celle de Paris, mais pour être honnête avec vous, elle la surpasse. Elle la surpasse à tous les niveaux ».

Une exception toutefois, a-t-il précisé :

« La seule chose qu’ils ont, c’est l’histoire […] Je dis toujours que c’est la seule chose avec laquelle on ne peut pas rivaliser, mais nous finirons par avoir cette histoire nous aussi. »

Le président est manifestement convaincu que son arche contribuera à forger cette histoire. « C’est la seule ville au monde d’une telle importance qui ne possède pas d’arc de triomphe », a-t-il déclaré à propos de Washington, DC.

Prévue à proximité du cimetière national d’Arlington et du Lincoln Memorial, l’implantation placerait la nouvelle structure en dialogue visuel avec plusieurs des monuments les plus emblématiques de la capitale fédérale.

Le projet s’inscrit par ailleurs dans une série d’initiatives destinées à laisser l’empreinte de Donald Trump sur le paysage bâti de Washington : les transformations apportées à la Maison-Blanche l’an dernier, avec notamment la minéralisation du célèbre Rose Garden, la décoration du Bureau ovale dans un style rococo doré, ou encore la démolition de l’East Wing pour permettre une extension de la salle de bal estimée à 400 millions de dollars (334,5 millions d’euros).

Surnommé l’« Arc de Trump », le projet est désormais la « priorité absolue » de Vince Haley, directeur du Conseil de politique intérieure de la Maison-Blanche.

Triomphe et architecture

L’Arc de triomphe de Paris, situé au sommet des Champs-Élysées, est une commande de Napoléon Bonaparte (1804-1814/1815) en 1806 pour honorer l’armée impériale française après sa victoire à la bataille d’Austerlitz (2 décembre 1805). Il ne sera achevé qu’en 1836, sous la Restauration et le règne de Louis-Philippe (1830-1848), dernier roi de France.

Les architectes du projet, Jean-François Chalgrin et Jean-Arnaud Raymond, se sont inspirés des arcs antiques, en prenant pour modèle principal l’arc de Titus à Rome (vers 85 de notre ère). Celui-ci fut érigé par l’empereur Domitien (51–96 de notre ère), tyran cruel et ostentatoire, populaire auprès du peuple mais en conflit permanent avec le Sénat, dont il avait restreint le pouvoir législatif. L’arc fut commandé par Domitien pour célébrer à la fois l’apothéose de son frère Titus et sa victoire militaire contre la rébellion en Judée.

Par ses références, l’arche proposée par Trump ne renvoie à aucun élément de conception spécifiquement américain. Son style néoclassique s’inscrit en revanche dans la continuité de monuments plus anciens, eux aussi inspirés de l’Antiquité.

Le Washington Monument, par exemple, adopte la forme d’un obélisque égyptien. Ce pilier à quatre faces, qui s’amincit en s’élevant et se termine par une pyramide, rend hommage au dieu solaire Rê. Mais il intégrait aussi un élément destiné à symboliser les avancées technologiques et l’esprit d’innovation américains : un pyramidion en aluminium. Lorsque l’obélisque a été achevé en 1884, l’aluminium était un matériau rare, le procédé permettant de le raffiner n’étant pas encore maîtrisé. Le sommet du monument constituait alors la plus grande pièce d’aluminium moulé au monde.

Un combat de valeurs

L’arc de triomphe voulu par Trump s’inscrit dans un débat de longue date sur les monuments publics et sur ce qu’ils disent des valeurs qu’une société choisit de mettre en avant.

Ainsi, pendant le mouvement Black Lives Matter, de nombreuses statues de figures historiques ont été retirées de l’espace public, car elles étaient perçues comme glorifiant le racisme et l’impérialisme. Donald Trump a depuis fait remettre en place au moins une statue confédérée renversée à cette période, et son ambition d’ériger un monument à sa propre personne ne saurait donc surprendre.

Sous le régime des lois Jim Crow (1877, abrogées en 1964), qui ont institutionnalisé la ségrégation raciale, puis durant le mouvement des droits civiques, le nombre de monuments consacrés aux soldats et aux généraux confédérés a connu une nette hausse.

De la même façon que le déboulonnage de ces statues relevait d’un geste politique, l’érection d’un nouveau mémorial destiné à promouvoir la lecture positive que Trump propose de l’histoire nationale en constitue un autre. Le projet s’intègre d’ailleurs dans la mission revendiquée par son administration de « restaurer la vérité et la raison dans l’histoire américaine ».

Reste une question plus immédiate : l’Independence Arch pourra-t-il seulement voir le jour d’ici au 4 juillet, jour de la fête nationale ? Un défi de taille, même pour ce président. Quant à son accueil, l’histoire tranchera.

ICE not only looks and acts like a paramilitary force – it is one, and that makes it harder to curb

Source: The Conversation – USA – By Erica De Bruin, Associate Professor of Government, Hamilton College

As the operations of Immigration and Customs Enforcement have intensified over the past year, politicians and journalists alike have begun referring to ICE as a “paramilitary force.”

Rep. John Mannion, a New York Democrat, called ICE “a personal paramilitary unit of the president.” Journalist Radley Balko, who wrote a book about how American police forces have been militarized, has argued that President Donald Trump was using the force “the way an authoritarian uses a paramilitary force, to carry out his own personal grudges, to inflict pain and violence, and discomfort on people that he sees as his political enemies.” And New York Times columnist Jamelle Bouie characterized ICE as a “virtual secret police” and “paramilitary enforcer of despotic rule.”

All this raises a couple of questions: What are paramilitaries? And is ICE one?

Defining paramilitaries

As a government professor who studies policing and state security forces, I believe it’s clear that ICE meets many but not all of the most salient definitions. It’s worth exploring what those are and how the administration’s use of ICE compares with the ways paramilitaries have been deployed in other countries.

The term paramilitary is commonly used in two ways. The first refers to highly militarized police forces, which are an official part of a nation’s security forces. They typically have access to military-grade weaponry and equipment, are highly centralized with a hierarchical command structure, and deploy in large formed units to carry out domestic policing.

These “paramilitary police,” such as the French Gendarmerie, India’s Central Reserve Police Force or Russia’s Internal Troops, are modeled on regular military forces.

The second definition denotes less formal and often more partisan armed groups that operate outside of the state’s regular security sector. Sometimes these groups, as with the United Self-Defense Forces of Colombia, emerge out of community self-defense efforts; in other cases, they are established by the government or receive government support, even though they lack official status. Political scientists also call these groups “pro-government militias” in order to convey both their political orientation in support of the government and less formal status as an irregular force.

They typically receive less training than regular state forces, if any. How well equipped they are can vary a great deal. Leaders may turn to these informal or unofficial paramilitaries because they are less expensive than regular forces, or because they can help them evade accountability for violent repression.

Many informal paramilitaries are engaged in regime maintenance, meaning they preserve the power of current rulers through repression of political opponents and the broader public. They may share partisan affiliations or ethnic ties with prominent political leaders or the incumbent political party and work in tandem to carry out political goals.

In Haiti, President François “Papa Doc” Duvalier’s Tonton Macouts provided a prime example of this second type of paramilitary. After Duvalier survived a coup attempt in 1970, he established the Tonton Macouts as a paramilitary counterweight to the regular military. Initially a ragtag, undisciplined but highly loyal force, it became the central instrument through which the Duvalier regime carried out political repression, surveilling, harassing, detaining, torturing and killing ordinary Haitians.

Is ICE a paramilitary?

The recent references to ICE in the U.S. as a “paramilitary force” are using the term in both senses, viewing the agency as both a militarized police force and tool for repression.

There is no question that ICE fits the definition of a paramilitary police force. It is a police force under the control of the federal government, through the Department of Homeland Security, and it is heavily militarized, having adopted the weaponry, organization, operational patterns and cultural markers of the regular military. Some other federal forces, such as Customs and Border Patrol, or CBP, also fit this definition.

The data I have collected on state security forces show that approximately 30% of countries have paramilitary police forces at the federal or national level, while more than 80% have smaller militarized units akin to SWAT teams within otherwise civilian police.

The United States is nearly alone among established democracies in creating a new paramilitary police force in recent decades. Indeed, the creation of ICE in the U.S. following the terrorist attacks of Sept. 11, 2001, is one of just four instances I’ve found since 1960 where a democratic country created a new paramilitary police force, the others being Honduras, Brazil and Nigeria.

ICE and CBP also have some, though not all, of the characteristics of a paramilitary in the second sense of the term, referring to forces as repressive political agents. These forces are not informal; they are official agents of the state. However, their officers are less professional, receive less oversight and are operating in more overtly political ways than is typical of both regular military forces and local police in the United States.

The lack of professionalism predates the current administration. In 2014, for instance, CBP’s head of internal affairs described the lowering of standards for post-9/11 expansion as leading to the recruitment of thousands of officers “potentially unfit to carry a badge and gun.”

This problem has only been exacerbated by the rapid expansion undertaken by the Trump administration. ICE has added approximately 12,000 new recruits – more than doubling its size in less than a year – while substantially cutting the length of the training they receive.

ICE and CBP are not subject to the same constitutional restrictions that apply to other law enforcement agencies, such as the Fourth Amendment’s prohibition on unreasonable search and seizure; both have gained exemptions from oversight intended to hold officers accountable for excessive force. CBP regulations, for instance, allow it to search and seize people’s property without a warrant or the “probable cause” requirement imposed on other forces within 100 miles, or about 161 kilometers, of the border.

In terms of partisan affiliations, Trump has cultivated immigration security forces as political allies, an effort that appears to have been successful. In 2016, the union that represents ICE officers endorsed Trump’s campaign with support from more than 95% of its voting members. Today, ICE recruitment efforts increasingly rely on far-right messaging to appeal to political supporters.

Both ICE and CBP have been deployed against political opponents in nonimmigration contexts, including Black Lives Matter protests in Washington, D.C., and Portland, Oregon, in 2020. They have also gathered data, according to political scientist Elizabeth F. Cohen, to “surveil citizens’ political beliefs and activities – including protest actions they have taken on issues as far afield as gun control – in addition to immigrants’ rights.”

In these ways, ICE and CBP do bear some resemblance to the informal paramilitaries used in many countries to carry out political repression along partisan and ethnic lines, even though they are official agents of the state.

Why this matters

An extensive body of research shows that more militarized forms of policing are associated with higher rates of police violence and rights violations, without reducing crime or improving officer safety.

Studies have also found that more militarized police forces are harder to reform than less-militarized law enforcement agencies. The use of such forces can also create tensions with both the regular military and civilian police, as currently appears to be happening with ICE in Minneapolis.

The ways in which federal immigration forces in the United States resemble informal paramilitaries in other countries – operating with less effective oversight, less competent recruits and increasingly entrenched partisan identity – make all these issues more intractable. Which is why, I believe, many commentators have surfaced the term paramilitary and are using it as a warning.
