Climate change boosted heat deaths by more than a third: Study

Extreme heat events aren’t just a matter of having a few uncomfortably warm days: they’re a real and recognized threat to public health, particularly for society’s most vulnerable.

Video Rate of extreme heat deaths accelerating with climate change

Now, with global temperatures continuing to rise, a new study says heat-related deaths over the last three decades were 37 per cent over and above what they would have been without the effects of climate change.

“Burdens varied geographically but were of the order of dozens to hundreds of deaths per year in many locations,” the researchers wrote in their paper, published this month in Nature Climate Change. “Our findings support the urgent need for more ambitious mitigation and adaptation strategies to minimize the public health impacts of climate change.”

The study arrived at those figures by comparing two climate models: one factoring in global warming due to human emissions, and one without. It was based on temperature and mortality data collected from 732 locations across 43 countries over a 28-year period from 1991 to 2018.

The researchers point out that the 37 per cent estimate is an average, and the figure would vary from country to country — for parts of the Middle East, Southeast Asia, and Central and South America, heat-related deaths were at least 50 per cent higher than what they would have been without the effects of climate change.

Global warming has been on the rise since the industrial era, but has been accelerating in recent years. NASA says the per-decade average increase since 1880 was 0.08°C, more than doubling to 0.18°C from 1980 to the present. The 10 hottest years on record have all occurred since 2005, and 2020 came within a hair’s breadth of taking the top spot from 2016.

Extreme heat events are on the rise, what this means for your health

In recent years, there’ve been several instances of large amounts of excess deaths that could be plausibly linked to individual extreme heat events. In August 2003, a heat wave in Europe was responsible for around 11,000 deaths in France alone, many of them seniors. In Montreal, a 2018 heat wave killed or hastened the deaths of 66 people, many of them among people with low income or social isolation, and triggered a public health investigation.

Many cities across Canada have extreme heat event protocols that open public cooling centres and employ other methods to reduce the risk to residents, but the researchers say more concerted action will be needed in the coming century.

"We expect the proportion of heat-related deaths to continue to grow if we don't do something about climate change or adapt," one of the lead authors, Dr. Ana Vicedo-Cabrera, said in a release from the University of Bern. "So far, the average global temperature has only increased by about 1°C, which is a fraction of what we could face if emissions continue to grow unchecked."

Even with efforts to limit future temperature rise, a certain amount of global warming is baked in at this point. Even the Intergovernmental Panel on Climate Change (IPCC), which advises governments on the science of climate change and recommends courses of action, doesn’t aspire to completely reverse the warming process: its current stated goals are to limit the warming to no more than 2°C above pre-industrial levels, and closer to 1.5°C if possible.

Canada, meanwhile, is actually warming twice as fast as the global average, and a study released last year by the Prairie Climate Centre offered a grim outlook on what that means for the kind of extended heat events that threaten public health.

The study found that, across most of Canada’s major cities, heat waves will be more frequent, last longer, and be slightly hotter on average than in previous decades, even in communities where they are relatively rare. In Ottawa, for example, heat waves could last at least 17 days by 2051–2080, up from the current average of four days. In Regina, the number of days that reach at least 34°C is expected to jump from three to at least 23 over the same period.

Western Canada heat wave expected to break daily, all-time temperature record

© Ben Nelms/CBC Vancouverites hit the beach on June 25, 2021, as a heat wave sets in throughout the province.

A heat wave stretching across Western Canada, from B.C. into southern Saskatchewan and up through the Yukon and the Northwest Territories, is set to break daily and all-time temperature records much earlier in the year than usual.

High pressure is trapped under a "heat dome," unable to be pushed through the country by wind, creating long-lasting high temperatures wherever the pressure sits, according to Armel Castellan, warning preparedness meteorologist with Environment Canada.

"Temperatures are then going to build on the previous day," he said.

"So you wake up in the morning and it's warmer than the day before."

© CBC News Western Canada is in for higher-than-average temperatures this weekend and through to next week.

Castellan said maximum temperatures in B.C. are expected Sunday and Monday, and Alberta will see its highest heat early next week.

Temperatures could approach 40 C in some parts of B.C. this weekend and through next week, and in Alberta early next week.

In Kamloops, B.C., the temperature is forecast to hover around 40 or 41 C for six consecutive days.

"Nobody's ever seen this because it's never happened, not in record keeping," Castellan said.

Little to no reprieve is expected overnight, he said, as overnight lows will remain between 15 and 20 degrees C.

It's the overnight temperatures that are the problem, Castellan said. They aren't going to dip low enough for our bodies to recover from the long, hot days.

"Even if we're in the shade, if we're dealing with temperatures well up into the 30s, in fact, even into the 40s for parts of southern B.C. and eventually into Alberta as well, those values are so extreme that our bodies need to recover," Castellan said.

This is where it becomes critical to watch for heat related illness, including heat exhaustion and heat stroke. Symptoms of heat related illness include, but are not limited to, heavy sweating, weakness, dizziness, nausea, headache and muscle cramps.

The increased heat comes with an increased risk of other climate emergencies, including forest fires, as trees and grasses dry out, creating more fuel.

Castellan said there is a zero per cent chance of lightning strikes in B.C. until Sunday afternoon, so if any fires start, they will likely be human caused.
Result of climate change

All this, Castellan said, is the result of climate change.

"What's important here is not so much the [temperature] itself today because, of course, the forecast isn't going to be perfect and it will maybe hit a couple degrees below or a couple of degrees above."

"What's important is to realize that this is part of what climate change is bringing us: more frequent, higher amplitude and longer lasting heat events."

Simon Donner, interdisciplinary climate scientist and geography professor at the University of British Columbia, said this heat wave is exactly what scientists have been warning will become more common because of human activity, in particular, if we don't reduce greenhouse gas emissions.

"As the climate warms, it basically means it's shifting the distribution of the weather," he said.

"So we're going to have more events like this and fewer cool summers."

As temperatures remain high at night over the coming days, sleeping will become a challenge for many without air conditioning in their homes. People, infrastructure and ecosystems will all struggle to manage during the extreme weather.

Donner said this is the essence of climate change.

Climate change isn't inherently a bad thing," he said. "The problem is the climate is changing faster than we can adapt."

Musician Bryan Adams calls for B.C. government's ouster over old-growth logging

Canadian musician Bryan Adams is urging British Columbians to vote out the NDP government in the next election over its support for old-growth logging in the province.

"I mean, this is disgraceful. This isn't what we voted for. People don't vote for tearing down ancient trees. If people knew more about what was going on, they would seriously be outraged," Adams told host Chris Hall in an interview for CBC's The House airing Saturday.

Protests against logging in the Fairy Creek watershed area have intensified this year, with activists blocking a road to the area. On May 17, the RCMP began enforcing an injunction to clear the camps and more than 260 people have been arrested since then.

On June 7, three First Nations in the area called for a two-year deferral of the logging. The provincial government agreed to pause operations two days later.

Adams is one of over 100 prominent Canadians who signed an open letter calling on B.C. Premier John Horgan to end old-growth logging in the province. For Adams and activist TJ Watt, who also joined The House, the temporary deferral granted by the provincial government isn't good enough.

"People are not going to be happy when they see that old-growth trees are still falling just outside those deferral areas. And the government's not taking this seriously," Watt said.

'It's just barbaric'

Adams said he and others were not calling for the end of all logging in the province. He said they want steps taken to protect old-growth trees, instead of letting loggers "plow through and cut everything down."


"It's just barbaric," he said.

Adams said that the protests in the Fairy Creek area are no different from other anti-logging protests that have taken place in British Columbia over the years — including those at Clayoquot Sound, one of the largest acts of civil disobedience in Canadian history.

"It's just the same old story over and over, over again," he said.

"This is my backyard again. It's still going on. When are people going to learn that these trees are invaluable to us? They don't come back and we've got to protect them."
Respecting role of First Nations

A key issue in the Fairy Creek situation has been the positions of First Nations, both for and against old-growth logging.

Soon after the Ditidaht, Huu-ay-aht and Pacheedaht First Nations requested the deferral, Huu-ay-aht Chief Coun. Robert J. Dennis Sr. told CBC Radio it was the protesters who were not being respectful of Indigenous rights.

"If you respect First Nations in what they stand for, if you respect First Nations Aboriginal title and if you respect First Nations people, period, you would honour their request not to protest," said Dennis.

Watt said Saturday it's up to governments to give First Nations additional resources so they aren't "forced to choose between logging of old-growth forests or losing the jobs and revenues that come from logging old-growth."

Provincial Forestry Minister Katrine Conroy told The House that working with Indigenous groups on developing forestry plans is the government's priority.

"I think it shows respect to ensure that we are talking to the Indigenous nations," Conroy said, urging others involved to do the same.

© Kieran Oudshoorn/CBC Activists from Ridge Camp watch the sunset from the top of the Fairy Creek watershed. Most have vowed to continue their opposition despite the recently negotiated two-year deferment of logging in the Fairy Creek and central Walbran areas.

"I really hope that people will respect the nations and respect their voices because reconciliation is tough.

"We can't only move forward with reconciliation when it serves our needs. We have to respect reconciliation is something we're doing in this province and we're very serious about it."

She said the government is working to adopt the 14 recommendations made in a report on old-growth forests released last year. The provincial government started that work last year, with the deferral of logging in nearly 200,000 hectares of old-growth forest.

Watt argued that the government's actions this year are not in line with the report's recommendations to halt logging on old-growth forests that are at risk.

Conroy said the provincial government would not be putting an end to logging in British Columbia altogether.

Conroy said that she wants to make sure that her grandchildren could, if they so choose, work in a sustainable and successful forestry industry.

"But I also want, if they so choose, to have the opportunity to walk in an old growth forest with their kids."

Hundreds brave sweltering heat for Black Lives Matter rally in Vancouver

Hundreds of people turned out to pressure the city for more action against racism at a Black Lives Matter protest at Vancouver City Hall on Friday.

© Global News Protesters try and keep to the shade at a Black Lives Matter rally in Vancouver on Friday amid near-record temperatures.

Organizers said the rally was about demanding justice and accountability, and standing in solidarity against white supremacy.

It came as former Minneapolis police officer Derek Chauvin was sentenced to 22 1/2 years in prison for the murder of George Floyd, and amid a dispute between Vancouver Mayor Kennedy Stewart and the city's police chief about the presence of systemic racism in policing.

Azuke Neuka-Agwu, one of the event's organizers, said the city has not done enough since demands from the Vancouver BLM chapter last June around defunding police, addressing systemic racism and redressing historic wrongs against the city's Black community.

"Even though the mayor recently chose to step down as (spokesperson for the Vancouver Police Board) and let someone else take it over, we're just not seeing enough progress, and COVID has provided so many distractions that people are just crashing form one spectacle to the next, without realizing all these things are connected," he said.

Neuka-Agwu drew a link between anti-Black racism, anti-Asian racism and anti-Indigenous racism and the rising number of hate crimes in Canada.

"The origin of the Canadian state, from clearing the land moving, the people out to residential schools, all of that is connected," he said, pointing to the recent discovery of the remains of hundreds of people at the sites of former Indian residential schools.

The recent wrongful handcuffing of an Indigenous grandfather and his 12-year old granddaughter and a retired Black B.C. Supreme Court judge in separate incidents were recent examples of systemic racism at work, he said.

"We are gashing to put pressure on the city to remind people that yeah, there are a lot of other things going on but this is still happening."

On Thursday, anti-racism advocate Markiel Simpson addressed the police board, calling for Chief Adam Palmer's resignation, amid the latter's refusal to acknowledge the presence of systemic racing in policing.

Later in the board meeting, Deputy Chief Steve Rai announced a review of VPD policies and procedures to ensure "systemic biases" were not embedded in the organization.

Sekoya Baker, who is Afro-Indigenous and a member of the Squamish and Tla'amin First Nations, said he was at the protest to remind the public that racism is not just something that happens in other countries.

"Even if we live in Canada and Vancouver, there's still a lot that's swept under the rug and not paid attention to. We're here to make a statement," Baker said.

"We need more allies, we need every person of colour to come together to let it be known, Indigenous lives matter, Black lives matter, stop Asian hate, everything.

His brother, Sekawnee Baker, said the priority was raising awareness.

"It's very important to me because I'm Afro-Indigenous. On both sides of my culture we've suffered some racism," he said.

"Being Black growing up here in Vancouver, I've faced some struggles. Being Native growing up here in Vancouver I've also faced some struggles."

Following speeches, demonstrators planned to march over the Cambie Street Bridge before ending at Emery Barnes Park for music and to hear from more speakers.

U.S. senator wants Canada on religious freedom watch list over pastor COVID arrests

EDMONTON — A U.S. senator has asked that Canada be investigated for violating religious freedom over the arrests of Alberta pastors accused of flouting COVID-19 restrictions.

In a letter released Thursday, Missouri Republican Josh Hawley asked his country's Commission on International Religious Freedom to consider putting Canada on its special watch list.

"I am troubled that our Canadian neighbours are effectively being forced to gather in secret, undisclosed locations to exercise their basic freedom to worship," Hawley wrote.

"Frankly, I would expect this sort of religious crackdown in Communist China, not in a prominent western nation like Canada."

Hawley refers in his letter to the arrests of Alberta pastors James Coates and Tim Stephens.

Coates spent a month in the Edmonton Remand Centre after he violated a bail condition not to hold church services that officials said were ignoring COVID-19 measures on capacity limits, physical distancing and masking. He was released March 22 after pleading guilty and was fined $1,500.

Coates, who is a pastor at GraceLife Church in Spruce Grove, has argued provincial regulations meant to curb the spread of COVID-19 infringed on his and his congregants' constitutional right to freedom of religion and peaceful assembly.

Earlier this month, a judge ruled his religious freedoms under the Charter were not violated.

Stephens remains in remand after being arrested last week following repeated public complaints over an outdoor service that officials say broke public health orders. Calgary police and Alberta Health Services allege that Stephens of Fairview Baptist Church chose to keep holding services without respecting orders on physical distancing and capacity limits, even after his church had been twice ordered closed.

Litigation director Jay Cameron of the Justice Centre for Constitutional Freedoms, which is representing Stephens, has accused Alberta Health Services in a statement of being "engaged in an intentional act of public deception and abuse of authority in arresting pastor Stephens and others."

The U.S. commission lists three requirements to declare that a country oppresses religious freedom. It says the oppression must be systematic, ongoing and egregious. Any two of those is enough to be placed on the special watch list. Countries already on the list include Afghanistan, Egypt, Cuba and Turkey.

A commission spokesperson said the agency is aware of Hawley's letter and is "looking into it."

A spokesman for Alberta Justice said the department couldn't comment on Hawley's accusations because the matters are still before the courts.

Hawley is a longtime supporter of former U.S. president Donald Trump. He gave a clenched-fist salute to the hordes outside the Capitol as he arrived on the day of the Jan. 6 riots to press his challenge of the presidential election results.

Alberta cabinet minister says daughter victim of hate-fuelled attack


CALGARY — An Alberta cabinet minister says her daughter has been the victim of hate-fuelled violence.

Rajan Sawhney, minister of community and social services, says her 25-year-old daughter was attacked Friday in downtown Calgary near her office in broad daylight.

In a post on Twitter, she says her daughter was grabbed, pushed, sworn at and chased as bystanders looked on.

She says her daughter wasn't physically hurt but is shaken, and so is she.

Sawhney noted that it happened at a time when there have been frequent attacks on racialized women over the past year.

She says she is now more motivated than ever to ensure that women, no matter where they come, can walk in public without fear of being attacked.

"I am outraged, saddened and disgusted at the same time, as I have been with every single attack on racialized women," Sawhney said.

The Calgary Police Service was not available for comment.

UBC faculty of medicine apologizes for harms to Indigenous Peoples


VANCOUVER — The University of British Columbia's faculty of medicine formally apologized Friday for its role in past and present harms to Indigenous Peoples and committed to expand its response to the Truth and Reconciliation Commission's calls to action.

Dr. Dermot Kelleher, the faculty's dean and vice-president of health, said the school recognizes that Indigenous-specific racism exists within the faculty and it apologizes for harmful attitudes and behaviours.


In the wide-ranging apology, he said the school regrets its role in educating and training anyone involved in colonial policy, and for excluding Indigenous people from admissions and in its hiring.

"We acknowledge the deep distress these actions have caused," Kelleher said.

"We intend to collectively forge a new path that takes us beyond this past and present by never, ever, ever forgetting it."

Kelleher made the apology during the faculty's official launch of "Reckoning with the Truth, Working Together for a Better Future: The UBC Faculty of Medicine Response to the Truth and Reconciliation Commission of Canada Calls to Action."

Although the school has made progress toward implementing the commission's calls to action related to health and education, it had not yet issued a formal response. Kelleher said the years-long process has taken longer than expected and there is still progress to be made.

"We now view the response as a living document and we know that it will change over time as additional insights and contributions are gained that expand our understanding of the issues."

Seven of the 94 calls to action in the commission's 2015 report relate specifically to Indigenous health. They include calls to recognize the value of traditional Indigenous health systems, to increase the recruitment and retention of Indigenous health-care practitioners, and for cultural sensitivity training for health workers.

Kelleher said as part of its response, the school is expanding a program that brings students into rural and Indigenous communities. It is also expanding a cultural safety training program. The school has hired more Indigenous faculty members and created positions to advise it on how to do better, he said.

Access to health care is a basic human right, yet Indigenous Peoples do not have equitable access to it, which must be corrected, Kelleher said.

"We know there is a long road ahead and more needs to be done," he added.

Several Indigenous leaders, elders and faculty members spoke at the event.

University chancellor Steven Point, a former lieutenant-governor, challenged other educational institutions to commit to implementing the commission's calls to action.

"Let's not repeat the same errors of the past but rather create a different future that's inclusive, that's fair, that acknowledges Indigenous contributions, that breeds a fair and level playing field," Point said.

Musqueam elder Larry Grant thanked the school for the apology and said he was also encouraged that the faculty of pharmacy is assigning practicum students to remote areas of the province. It gives the students first-hand knowledge of the inadequacies of health programs and the quality of medicine available to Indigenous communities, he said.

University president Santa Ono apologized in 2018 to residential school survivors and Indigenous people for its role in the system that supported the operation of the schools.

A report released in November by former judge Mary Ellen Turpel-Lafond found widespread systemic racism in British Columbia's health-care system. She said 84 per cent of the review's Indigenous respondents reported some form of discrimination in health care and 52 per cent of Indigenous health-care workers said they experienced racial prejudice at work, mostly in the form of comments.

Potato and rice protein shakes may be a viable vegan alternative to whey protein shakes

UNIVERSITY OF WESTMINSTER

Research News

 

A study from the Centre for Nutraceuticals at the University of Westminster found that plant-based protein shakes may be potential viable alternatives to milk-based whey protein shakes, particularly in people with need of careful monitoring of glucose levels.

The study, published in the journal Nutrients, is the first to show potato and rice proteins can be just as effective at managing your appetite and can help better manage blood glucose levels and reduce spikes in insulin compared to whey protein.

During the study the blood metabolic response of participants was measured after drinking potato, rice and whey protein shakes. Appetite was also monitored in the following three hours to understand how these drinks may affect the participants' hunger and their desire to eat.

The research observed that vegan protein shakes led to a lower rise in blood insulin compared to whey, while potato protein prevented any rise in insulin. This may explain the better blood glucose control following consumption of the plant-based protein and poses the question of whether vegan protein shakes are more suitable for individuals who need to need control their blood glucose levels such as diabetic and obese individuals.

Interestingly, release of the key appetite regulating hormone GLP-1 was greater after drinking the whey protein shake. However, the greater GLP-1 response did not translate to an increased feeling of fullness as there were no differences observed in appetite perception between the three different protein shakes.

Consumer trends in protein intake are on the rise with milk protein derivatives such as whey extensively used in consumer products such as protein shakes, fortified food and beverage products.

There are alternative protein products available for vegetarians and vegans such as soy, rice, wheat and pea proteins but there is a relative lack of evidence on their health benefits in comparison to milk proteins. Potato protein is a novel plant-based protein product that is obtained from the waste material from potato starch production and is a sustainable economic protein source. This study provides the first evidence to suggest that it may be an alternative to whey protein sources.

Professor M Gulrez Zariwala, corresponding author and Director of the Centre for Nutraceuticals at the University of Westminster, said: "Global concerns on sustainability have led to consumer shifts towards ethical eating and a change in dietary habits with increased adoption of vegetarian and vegan diets.

"However, research in this area is still lacking and it would be interesting to clarify whether proteins from plant sources can provide identical metabolic health benefits as those with traditional sources such as milk.

"Our results shed new light in this area and improves our understanding of how plant source proteins can be a more sustainable yet nutritionally beneficial food source. We plan to conduct follow-up studies further research this exciting area."

'Subterranean estuaries' crucial to sustainable fishing and aquaculture industries

TRINITY COLLEGE DUBLIN

Research News

 

Pioneering research, led by a team from Trinity College Dublin and the Marine Research Institute of the Spanish Research Council (IIM-CSIC) in Vigo (Galicia, Spain), suggests "subterranean estuaries" may be critical in managing sustainable fishing and aquaculture - two growing industries of global importance.

Subterranean estuaries are analogous to surface water estuaries, where freshwater flowing out to sea mixes with seawater, but are instead located underground, invisible to the naked eye. Yet the newly published research shows these hidden features are very important in the ecology of coastal systems and in filtering pollutants - some of which have been slowly travelling to sea for decades having leached from agricultural soils.

The research, just published open access in Limnology and Oceanography, uncovered subterranean estuaries in the Ria de Vigo in Galicia (one of the most productive coastal ecosystems in Europe and leader in bivalve production for human consumption) and assessed their importance to the coastal environment.

By employing a selection of natural environmental tracers that carry the chemical fingerprints of groundwater sources on land out to sea, the team estimated that almost 25% of the continental freshwater discharged to the Ria de Vigo comes from this invisible source.

The Biogeochemistry Research Group of Trinity's School of Natural Sciences, led the study (Project SUBACID). Explaining the significance of the work, and its wider implications for Irish waters, Carlos Rocha, Professor in Environmental Change, said:

"Bivalve aquaculture is a strategic, expanding sector in Irish sustainable development and features highly in the national plans to diversify food production. While our work was conducted in the Ria de Vigo, this area was carefully selected because of its capability to support aquaculture and its biogeographic similarity to parts of the Irish coastline.

"These subterranean estuaries have a high capability to filter out pollutants, like fertilisers, from freshwater. Given the extent to which they supply large ecosystems with incoming freshwater, they have a much more important role to play than many would have believed."

Juan Severino Pino Ibánhez, researcher from the Marine Research Institute-CSIC (Spain), added:

"We will now focus in more detail on which specific ecosystem services these invisible structures provide, and how they might affect, for example, the ongoing threat to this industry posed by ocean acidification caused by anthropogenic CO2 emissions to the atmosphere.

"We are currently strengthening the collaborative network established with the Marine Research Institute of Vigo to elucidate the functioning of these hidden ecosystems and their role in coastal health and resilience. Lessons learnt in Vigo together with ongoing research made by our group in Irish coastal ecosystems will help to understand the future of Irish coastal ecosystem services and food production."
