Experts uncover the water and emissions footprint of snowmaking: Can we rely on it in an era of climate change?

Peer-Reviewed Publication

TAYLOR & FRANCIS GROUP

The first-ever national study to assess the impact of developing artificial snow shows the pressure the process is putting on the climate, with the equivalent of nearly 17,000 homes’ worth of annual energy needed to produce snow for yearly ski operations in just Canada alone.

Publishing their findings in the peer-reviewed journal Current Issues in Tourism, experts from the University of Waterloo, in Canada, and the University of Innsbruck, Austria, found 130,095 tonnes CO2e are needed to produce the estimated 42 million cubic meters of machine-made snow in Canada in an average winter.  For context, this is comparable to 155,141 acres of forest for one year sequestering the comparable amount of carbon.

As more snowmaking is needed under future climate change, water and energy requirements will continue to grow even as average ski seasons get shorter in the decades ahead.

In order to make snowmaking, and indeed skiing in Canada more sustainable, the team calls for collaboration between ski operators, policymakers, and environmental organizations, and skiers to develop and support comprehensive policies and practices that “prioritize sustainability in addressing the challenges posed by climate change and its associated impacts on snowpack”.

“Our results emphasize the need to adopt a systems approach to ensure the long-term sustainability of ski tourism,” says co-author Professor Daniel Scott, from the Geography and Environmental Management department at Waterloo.

“This will include embracing innovation and investing in energy-efficient snowmaking technologies, promoting water conservation measures, and accelerating the transition to renewable energy sources.

“Snowmaking can actually help reduce total emissions from tourism when it enables millions of skiers to ski regionally instead of driving or flying to far off ski resorts or selecting another type of carbon intense holiday. Net-zero compatible ski holidays are already possible in destinations like Quebec and our study shows a vibrant and resilient future for ski tourism is possible.”

Winter mountain destinations are a key part of the tourism sector in Canada. Currently there are 237 ski areas operating and hosting an average of 18.2 million skier visits, including 2.7 million international visits.

This, however, comes with implications for the long-term sustainability of ski tourism. Based on the current electrical grid carbon intensity, the team found that snowmaking in Canada uses 478,000 megawatt-hours (MWh) of electricity annually, resulting in 130,095 tonnes of associated CO2 emissions – and an estimated 43.4 million cubic meters of water to produce over 42 million cubic meters of technical snow.

As climate change continues to exert its impact on the snowpack in ski areas around the world, ski operators are increasingly relying on snowmaking to maintain ski seasons and provide an enjoyable experience for visitors.

In Canada, the study estimated snowmaking requirements to increase between 55% and 97% by 2050. Water and energy requirements will rise proportionally, assuming terrain coverage and average snowmaking efficiencies remain static.

However, in Canada at least, good news appears to be on the horizon which much-needed decarbonization policies, which Professor Scott says will decrease ski operations related emissions “substantially”.

“What we can see is that snowmaking emissions are expected to decline substantially, thanks to the ongoing efforts to decarbonize provincial electricity grids in alignment with current policy targets. Future emissions will also be influenced by various other factors, including upgrades in snowmaking and grooming technology and increased terrain coverage.”

The authors state, that while this research provides an essential first evaluation of the environmental impacts of snowmaking, and its potential sustainability, changes in emissions and water use will need to be reassessed alongside destination-level sustainable development as climate change accelerates and decarbonization targets are pursued.

UCDP: Number of deaths in armed conflicts has doubled

Reports and Proceedings

At least 237,000 people died in organised violence in 2022. A new report from Uppsala Conflict Data Program (UCDP) at Uppsala University shows that this is a 97 per cent increase compared with the previous year, and the highest number since the Rwandan genocide in 1994.

“We see this increase despite considerable de-escalation in the two deadliest conflicts of 2021; Yemen and Afghanistan. Instead, violence in Ethiopia and Ukraine escalated drastically,” says Shawn Davies, Senior Analyst at UCDP.

Together, the wars in Ethiopia and Ukraine resulted in at least 180,000 battle-related deaths in 2022. This is a low estimate as information from these conflicts is scarce and subject to extensive propaganda. The numbers are likely to be significantly revised as more information becomes available. Even so, the data shows that more people died in those two conflicts in 2022 than in the whole world the year before.

“A common perception is that Russia’s war in Ukraine was the bloodiest conflict in 2022, but in fact, more people died in Ethiopia where the Tigray People's Liberation Front (TPLF) has fought the Ethiopian army, the latter supported by Eritrea, since late 2020,” says Davies.

In both Ethiopia and Ukraine, fighting has been characterised by trench warfare, with warring parties being accused of using human wave tactics. This type of warfare has contributed to the high casualty numbers.

The Russian invasion of Ukraine in February 2022 is the first large-scale interstate war in 20 years. Even if conflicts between states remain a relatively rare occurrence, they have increased in recent years.

“It has also become more common for external states to send troop support to rebel groups fighting against other governments, which essentially means that state armies are fighting each other,” says Therese Pettersson, Project Leader at UCDP.

The number of active conflicts in the world remains at a historically high level. UCDP registered 55 different conflicts where a state was involved on one or both sides during 2022. In contrast, between 31 and 39 such conflicts were registered yearly between 2000 and 2013, whilst the annual number has varied between 52 and 56 from 2015 onwards.

“Albeit most conflicts are small, the number of wars increased from five in 2021 to eight in 2022. Conflicts causing at least 1,000 battle-related deaths during one calendar year are considered wars,” Pettersson clarifies.

The number of non-state conflicts, where rebel groups or other armed organised actors fight each other, also remains on a record high level. UCDP registered 82 such conflicts in 2022. Nine of the ten deadliest non-state conflicts of the year occurred in Mexico where rival drug cartels have fought each other over turf since the 1980s. Gang-related violence has also escalated in Brazil, Haiti, Honduras and El Salvador in recent years.

Furthermore, so-called one-sided violence, where civilians are the target, increased in 2022. At least 11,800 civilians were killed in this type of intentional, targeted violence, carried out by 45 different states or organised groups. The actor killing most civilians in one-sided violence was the Islamic State (IS), but states also attacked civilians on a large scale in several conflicts. Russia and Eritrea both used extensive violence against civilians in the wars in Ukraine and Ethiopia.

The results presented in the press release will be published in the July issue of the Journal of Peace Research.

Pathways to global sustainability revealed through a worldwide survey of experts

Peer-Reviewed Publication

UNIVERSITY OF EASTERN FINLAND

The majority of sustainable development researchers believe that in affluent countries, it is necessary to look beyond economic growth to achieve sustainable development, a recent study from the University of Eastern Finland suggests. The study, published in the scientific journal Ecological Economics, investigated the preferred future paths for countries at different income levels among 461 sustainability scholars. The survey results shed light on the strategic choices necessary for achieving global sustainability.

The study focused on green growth and post-growth economic strategies. The green growth strategy aims to enhance both societal and environmental well-being as the economy grows. On the other hand, post-growth paths question this approach and advocate for a shift beyond growth, focusing on environmental and societal well-being instead of economic growth.

“This research reveals that an overwhelming majority of sustainability scholars, over 75 percent, support post-growth pathways for affluent countries already this decade. For less affluent countries, the majority of scholars favoured either green growth or post-growth pathways,” says Postdoctoral Researcher Teemu Koskimäki from the University of Eastern Finland, who conducted the study.

Different paths are needed in countries with different income levels

In the study, scholars were asked to choose which pathways should be pursued in different country income groups in the 2020s and 2030s in order to achieve sustainable development globally. A comparison of the responses revealed that support for post-growth paths increased over time, while support for green growth declined in all contexts. Koskimäki emphasizes that the research results challenge the prevailing green growth focused approach.

“Currently, global Sustainable Development Goals are based on green growth. However, researchers emphasize the urgent need to consider post-growth strategies, particularly in affluent countries.”

Koskimäki stresses the critical importance of understanding the views of sustainability scholars on suitable paths for countries of different income levels.

“Policy-makers at various levels and sectors may rely on these experts as they implement the UN 2030 Agenda for Sustainable Development.”

Although sustainability scholars favour post-growth paths, the study shows they are not as familiar with this approach as they are with green growth.

“In my study, I address the challenges that this gap in knowledge and skills can create for achieving global sustainability,” Koskimäki says.

GDP is an insufficient measure of societal well-being

The study also found that most sustainability scholars who responded to the survey consider Gross Domestic Product, GDP, to be an inadequate measure of societal well-being.

“This underscores the need for a broader discussion of progress indicators, especially for wealthier countries, where the costs of continued consumption growth exceed its benefits,” says Koskimäki.

Based on the study's conclusions, research, education, and policymaking should pay attention to targeted transformative change, with a particular focus on facilitating post-growth strategies in the wealthiest countries.

The study offers critical perspectives on the equitable and efficient implementation of various sustainability strategies and underscores the need for targeted approaches that take economic disparities between countries into account. According to Koskimäki, this recognition could facilitate the equitable and efficient achievement of sustainability, both locally and globally.

“The study reveals a potential contradiction between those sustainability paths addressed in sustainability reports and by political decision-makers, and those favored by scholars. A broader, more inclusive conversation is needed to ensure that we are targeting the right transformations and implementing them in a controlled manner,” Koskimäki concludes.

Does evening “recovery” affect a person’s mood at work the next day?

Peer-Reviewed Publication

WILEY

The quality of recovery a person experiences on a given evening after work may impact their mood when they start their job again the next day, according to new research published in the Journal of Occupational and Organizational Psychology.

The study, which was based on diary entries by 124 employees on 887 days, found that people who had higher quality recovery during the evening than usual had higher levels of wakefulness, calmness, and pleasantness when they started work the next day. However, people’s wakefulness and calmness tended to decline more strongly during the workday after evenings with higher quality recovery.

These findings imply that employees benefit from daily recovery, but these benefits subside during the workday. Therefore, it’s important to engage in recovery on a daily basis.

“Our study shows that daily recovery from work during off-job time is indeed beneficial for employees’ mood; however, these benefits do not last the entire workday. Thus, our findings highlight that the benefits of evening recovery are relatively short-lived,” said corresponding author Maike Arnold, MSc, of the University of Mannheim, in Germany. “We further found that some but not all of these benefits can be explained by a better sleep quality following good evening recovery.”

Remnants of ancient virus may fuel ALS in people

Study identifies promising new target for treating underlying cause of the fatal disease

Peer-Reviewed Publication

UNIVERSITY OF COLORADO AT BOULDER

More than 5,000 people are diagnosed annually with ALS (amyotrophic lateral sclerosis), a fatal, neurodegenerative disease that attacks nerve cells in the brain and spinal cord, gradually robbing people of the ability to speak, move, eat and breathe.

To date, only a handful of drugs exist to moderately slow its progression. There is no cure.

But CU Boulder researchers have identified a surprising new player in the disease—an ancient, virus-like protein best known, paradoxically, for its essential role in enabling placental development.

The findings were recently published in the journal eLife.

“Our work suggests that when this strange protein known as PEG10 is present at high levels in nerve tissue, it changes cell behavior in ways that contribute to ALS,” said senior author Alexandra Whiteley, assistant professor in the Department of Biochemistry.  

With funding from the ALS Association and the National Institutes of Health, and Venture Partners, her lab is now working to understand the molecular pathways involved and to find a way of inhibiting the rogue protein.

“It is early days still, but the hope is this could potentially lead to an entirely new class of potential therapeutics to get at the root cause of this disease.”

Ancient viruses with modern-day impact

Mounting research suggests about half the human genome is made up of bits of DNA left behind by viruses (known as retroviruses) and similar virus-like parasites, known as transposons, which infected our primate ancestors 30-50 million years ago. Some, like HIV, are well known for their ability to infect new cells and cause disease.

Others, like wolves who have lost their fangs, have become domesticated over time, losing their ability to replicate while continuing to pass from generation to generation, shaping human evolution and health.

PEG10, or Paternally Expressed Gene 10, is one such “domesticated retrotransposon.” Studies show it likely played a key role in enabling mammals to develop placentas—a critical step in human evolution.

But like a viral Jekyll and Hyde, when it’s overly abundant in the wrong places, it may also fuel disease, including certain cancers and another rare neurological disorder called Angelman’s syndrome, studies suggest.

Whiteley’s research is the first to link the virus-like protein to ALS, showing that PEG10 is present in high levels in the spinal cord tissue of ALS patients where it likely interferes with the machinery enabling brain and nerve cells to communicate.

“It appears that PEG10 accumulation is a hallmark of ALS,” said Whiteley, who has already secured a patent for PEG10 as a biomarker, or way of diagnosing, the disease.

Too much protein in the wrong places

Whiteley did not set out to study ALS, or ancient viruses.

Instead, she studies how cells get rid of extra protein, as too much of the typically good thing has been implicated in other neurodegenerative diseases, including Alzheimer’s and Parkinson’s.

Her lab is one of a half-dozen in the world to study a class of genes called ubiquilins, which serve to keep problem proteins from accumulating in cells.

In 2011, a study linked a mutation in the ubiquilin-2 gene (UBQLN2) to some cases of familial ALS, which makes up about 10% of ALS cases. The other 90% are sporadic, meaning they are not believed to be inherited.

But it has remained unclear how the faulty gene might fuel the deadly disease.

Using laboratory techniques and animal models, Whiteley and colleagues at Harvard Medical School first set out to determine which proteins pile up when the UBQLN2 misfires and fails to put the brakes on. Among thousands of possible proteins, PEG10 topped the list.

Then Whiteley and her colleagues collected the spinal tissue of deceased ALS patients (provided by the medical research foundation Target ALS) and used protein analysis, or proteomics, to see which if any seemed overexpressed.

Again, among more than 7,000 possible proteins, PEG10 was in the top five.

In a separate experiment, the team found that with the ubiquilin brakes essentially broken, the PEG10 protein piles up and disrupts the development of axons—the cords which carry electrical signals from the brain to the body.

PEG10 was overexpressed in the tissue of individuals with both sporadic and familial ALS, the study found, meaning the virus-like protein may be playing a key role in both.

“The fact that PEG10 is likely contributing to this disease means we may have a new target for treating ALS,” she said. “For a terrible disease in which there are no effective therapeutics that lengthen lifespan more than a couple of months, that could be huge.”

The research could also lead to a better understanding of other diseases, which result from protein accumulation as well as keener insight into how ancient viruses influence health.

In this case, Whiteley said, the so-called “domesticated” virus could a be rearing its fangs again.

“Domesticated is a relative term, as these virus-like activities may be a driver of neurodegenerative disease,” she said. “And in this case, what is good for the placenta may be bad for neural tissue.”

Motor skills and physical activity practice supports preschoolers’ learning

A doctoral thesis has demonstrated that motor skills and physical activity practice can support the cognitive and early academic skills of preschoolers.

Reports and Proceedings

UNIVERSITY OF HELSINKI

A doctoral thesis has demonstrated that motor skills and physical activity practice can support the cognitive and early academic skills of preschoolers, particularly when the activities include motor skills practice, or when motor skills or physical activity practice is combined with the subject to be learnt.

In recent years, concerns have been raised about children and adolescents being less physically active and having weaker motor skills than previous generations. A further cause of concern is the decline of for instance mathematical and language skills, with an increasing number of children in schools and kindergartens needing support in their learning. Prior research has shown that physical inactivity is a new risk factor for skills development. 

Doctoral Researcher Pinja Jylänki from the University of Helsinki investigated whether physical activity and motor skills practice can support the development of cognitive and early academic skills in children of preschool age.

Physical activity or motor skills practice should be combined with the subject taught

In systematic reviews included in her doctoral thesis, Jylänki examined a total of 57 previously completed studies on the topic. Roughly 70% of these studies had demonstrated that motor skill and physical activity interventions have positive effects on preschoolers’ cognitive and early academic skills. 

Effects had been observed particularly in children’s memory and executive function as well as language and early numeracy skills. The most marked effects were seen as a result of motor skills practice, or when motor skills or physical activity practice was combined with the topic being taught. 

“The findings support the idea that practising one skill, motor skills in this case, supports the learning of another skill, that is, early academic or cognitive skills, more than a quantitative increase of physical activity alone,” Jylänki says.

Based on the prior research, it is also advisable to combine the practice of different skills, as such combination was found to be more effective compared to practising motor skills or physical activity exclusively.

However, the field is relatively new, and further research of a high standard is needed to verify the results.

Intervention programme narrowed down learning differences in early numeracy skills

In her doctoral thesis, Jylänki and her colleagues developed an intervention programme called Movement with Early Numeracy. This programme for practising motor and early numeracy skills is designed for Finnish early childhood education. It supports children with challenges in early numeracy skills.

Movement with Early Numeracy combines the practice of numerical concepts with motor skills practice. Concepts describing numerical relational skills, such as ‘more’, ‘less’ or ‘half’ and ‘whole’, were first practised in a story read for children, after which the same concepts were incorporated into motor skills training. The effects of practice were observed in 36 children.

According to the study, the effects were positive, and a delayed measurement showed that the effects remained approximately eight weeks following the intervention. Moreover, differences in numerical relational skills decreased in the eight-week period between children whose performance was lower at the beginning of the intervention and the average performance control group. There were no significant differences between the groups at the end of the intervention. 

“The novelty value of this finding is boosted by the fact that, in previous intervention programmes for early numeracy practice, long-term effects or the narrowing of differences between children with lower and average performance have not often been identified,” Jylänki says.

Jylänki’s doctoral thesis is part of the Active Early Numeracy research project led by Professor Pirjo Aunio (University of Helsinki) and Associate Professor Arja Sääkslahti (University of Jyväskylä).

Jylänki will continue, together with the Active Numeracy research group, to investigate the Movement with Early Numeracy intervention programme using a larger sample.

To gain more information on the effects of the intervention, its effects will also be compared with those of practising motor skills or early numeracy alone. Following the completion of these studies, the programme will be released for public use free of charge.

Pinja Jylänki, Master of Sport Science, defended her doctoral thesis entitled “Active Early Interventions - Supporting Preschoolers’ Cognitive and Academic Skills with Fundamental Motor Skill and Physical Activity Interventions” on 5 May 2023 at the Faculty of Educational Sciences, University of Helsinki.

Animals can defend themselves against their natural enemies in various ways. Well-defended species often share conspicuous body colors with other well-defended or undefended species, forming mimetic interactions. Bombardier beetles eject toxic chemicals at a temperature of 100°C to repel enemies such as frogs, and many have warning body colors that function to deter enemies. An assassin bug, Sirthenea flavipes, exhibits a conspicuous body color similar to the bombardier beetle Pheropsophus occipitalis jessoensis which coexist with the assassin bug in the same habitat in Japan (Fig. 1). The assassin bug can stab with its proboscis, causing severe pain in humans. Although both insects are well defended, the mimetic interaction between the bombardier beetle and the assassin bug remains unclear.

Japanese entomologists Shinji Sugiura (Kobe University) and Masakazu Hayashi (Hoshizaki Green Foundation) found that the bombardier beetle P. occipitalis jessoensis has a stronger defense against a shared predator compared to the assassin bug S. flavipes. They also showed that both the bombardier beetle and the assassin bug benefit from the mimetic interaction via the shared predator. Their research appears in the 6 June 2023 issue of PeerJ.

In central Japan, the pond frog Pelophylax nigromaculatus coexists with the bombardier beetle and the assassin bug in the same habitat. The pond frog, which is well known as a predator of various insects, could potentially attack the bombardier beetle and the assassin bug under field conditions. The researchers observed the behavioral response of pond frogs to bombardier beetles and assassin bugs under laboratory conditions (see video). Among the frogs, 100% rejected bombardier beetles and 75% rejected assassin bugs (Fig. 2), suggesting that the bombardier beetle is better defended against frogs than the assassin bug. The researchers also provided a bombardier beetle or an assassin bug to a frog that had encountered the other insect. Frogs that had previously encountered one insect species were less likely to attack the other species (Fig. 3). Specifically, a history of encounter with assassin bugs reduced the rate of attack on bombardier beetles by frogs from 75.0% to 21.7% (Fig. 3). A history of encounter with bombardier beetles reduced the rate of attack on assassin bugs by frogs from 91.3% to 40.0% (Fig. 3). Therefore, the mimetic interaction between the bombardier beetle and the assassin bug may be mutualistic.

PORT WORKERS WOBBLE THE JOB

West Coast labor dispute threatens commerce, supply chain at nation's busiest port

Operations mostly back to normal but delays widespread after weekend walkout


Labor disruptions at several ports along the West Coast caused concerns for potential shipping delays that began to clear up by the start of the week. File Photo by Jim Ruymen/UPI | License Photo

June 6 (UPI) -- Operations at multiple ports from Los Angeles to Seattle returned to normal Monday after a multi-state walkout that began late last week when unionized shipping employees in Oakland refused to show up for work.

The strike threatened to strangle commerce at the nation's busiest port -- the Port of Los Angeles -- which processes $440 billion in cargo per year even as a large portion of trade had transferred to the East Coast over the past year due to increasing labor issues.

The latest disruption caused a headache for ocean cargo deliveries, with incoming ships from China forced into irregular circling patterns in the Pacific as the worker dispute played out on shore.

Only one ocean cargo ship headed to Hawaii was expected to be delayed but was still scheduled to arrive in Honolulu on Thursday.

The walkout caught much of the industry off guard as it extended through the weekend before ports reopened for several hours Monday.

The strike disrupted the typically hot start of the peak shipping season in the United States and prompted the National Retail Federation to call on the Biden administration to step in and negotiate the growing dispute between labor unions and port officials.

Before the strike, supply chains along the West Coast were already struggling to return to pre-pandemic levels.

At least 52 Chinese shipping vessels were said to be making their way toward the Port of Los Angeles in a sign that shipping could soon be back to normal.

Truckers with ITS Logistics were halted at the gates of the Fenix Marine Services terminal at the Port of Los Angeles Monday, preventing the delivery of shipping containers owned by Maersk, COSCO and other corporate giants following several "extremely frustrating" encounters with port authority officials over the past several days.

By Tuesday, operations appeared to be fully running again, although wait times had increased at the Port of Los Angeles and Port of Long Beach, and even more so at the Port of Oakland as work shifts were reshuffled, according to CNBC.

A day earlier, the Long Beach port shut down the day shift of two of its six container terminals.

"Navigating the ports on the entire West Coast over the last four days has been extremely frustrating for us and our clients," said Paul Brashier, vice president of drayage and intermodal at ITS Logistics. "If it were not for updates from our drivers and our visibility software applications, we would not have even known about terminal closures Friday, throughout the weekend, and into today."

Brashier also accused the International Longshore and Warehouse Union of misleading the public in its announcements about ongoing talks to reach a new contract with port managers.

Brashier also said port officials didn't give the trucking company any heads up about the work stoppage and that he first heard of the lockdown from truckers who had been turned back earlier at Fenix Marine terminal.

However, the terminal did send out a prior communication to companies that alerted to forthcoming cancellations the complex.

Meanwhile, the Los Angeles Port's Pacific Container Terminal announced a plan to shutter its Tuesday dayside shift following a scheduled closure by the facility on Monday that was announced last week.

EPA announces $115 million for Jackson, Miss., water infrastructure

June 6 (UPI) -- Jackson, Miss. received a federal lifeline in its water crisis on Tuesday with the Environmental Protection Agency promising $115 million to support critical water infrastructure in Mississippi's capital city.

The funds, which are coming from the 2023 federal budget in money Congress set aside for infrastructure, come to a city plagued by water infrastructure issues that have left it without reliable clean drinking water at times

In October, the EPA opened an investigation into whether Mississippi state officials discriminated against Black residents in the state by declining to fund improvements to the state's water supply.

"These funds will help provide relief to Jackson residents, who have suffered decades of water insecurity," Jackson Mayor Chokwe Antar Lumumba said in a statement. "This aid helps to restore dignity to our city."

In addition to this appropriation, the city of Jackson and the state of Mississippi are eligible for tens of millions of dollars in additional financial support to support water infrastructure upgrades.

"Last summer, the city's water system reached a crisis point when a major flood aggravated longstanding problems in the system and left tens of thousands of people without any running water for days on end," President Joe Biden said in a statement on Tuesday.

"All Americans deserve access to clean, safe drinking water. That's why I directed my administration to make sure the people of Jackson have the resources they need and deserve."

RELATED Evangelicals have moved from environmental stewardship to climate skepticism

Last August, Mississippi and Biden declared a state of emergency due to the drinking water crisis in Jackson, which affected its population of 180,000. Biden ordered FEMA to organize relief efforts to help distribute water.

"This is an incredible milestone towards ensuring access to safe drinking water for the Jackson, Mississippi community," said Rep. Bennie Thompson, D-Miss. "It is a testament to the work Congress has done to provide this funding to Jackson through the bipartisan 2023 federal budget and is a first step in resolving the water crisis for the citizens of Jackson."

MONTREAL (AP) — Northern Quebec’s largest town was being evacuated on Tuesday as firefighters worked to beat back threats from out-of-control blazes in remote communities in the northern and northwestern parts of the province.

According to the province’s forest fire prevention agency, more than 150 forest fires were burning in the province on Tuesday, including more than 110 deemed out of control. The intense Canadian wildfires are blanketing the northeastern U.S. and parts of Eastern Canada in a haze, turning the air acrid, the sky yellowish gray and prompting warnings for vulnerable populations to stay inside.

The effects of hundreds of wildfires burning in Quebec could be felt as far away as New York City and New England, blotting out skylines and irritating throats.

Late Tuesday, authorities issued an evacuation order for Chibougamau, Quebec, a town of about 7,500 in the remote region of the province. Authorities said the evacuation was underway and promised more details Wednesday.

“We’re following all of this from hour to hour, obviously,” Premier François Legault told reporters in Sept-Îles, Quebec. “If we look at the situation in Quebec as a whole, there are several places where it is still worrying.”

Legault said the Abitibi-Témiscamingue region in northwestern Quebec is an area of particular concern, with the communities of Normétal and Lebel-sur-Quévillon under threat.

The mayor of Lebel-sur-Quévillon, where about 2,100 people were forced from their homes on the weekend, said the fire is about 10 kilometers (six miles) outside of town, but its advance has been slower than expected.

“The fire started in an area where there were no trees, which slowed it down considerably,” Mayor Guy Lafrenière said.

Other northern communities at risk include Chibougamau the Cree village of Chisasibi on the eastern shore of James Bay. Firefighting resources have also been dispatched to Hydro-Québec’s Micoua substation near Baie-Comeau, Legault said.

On Monday, Legault said authorities had no choice but to leave the hamlet of Clova to burn, drawing the ire of local residents. Legault said Tuesday that he had simply repeated what fire prevention officials told him: the fire around the tiny community about 325 kilometers (201 miles) northwest of Montreal was too intense to send water bombers. That remained true Tuesday, he said, but he noted that no homes had burned.

Dominic Vincent, the owner of the Auberge Restaurant Clova, said that by Monday afternoon, the situation in the area had already improved, aided by cooler temperatures and a change in wind direction. While smoke remained visible, it was far less intense, he said.

Quebec Natural Resources Minister Maïté Blanchette Vézina told reporters in Quebec City that evacuees across the province number just over 8,300, down from 10,000 to start the week, but the Abitibi region remains a concern.

“We are not expecting rain in the short term, which is what makes it more difficult to fight fires,” Blanchette Vézina said.
