Climate change and health in Canada

The Prairie Climate Centre at the University of Winnipeg maintains the Climate Atlas of Canada, and on November 20  launched a new section of their website devoted to climate change and health in Canada.   So far, the webpages provide a general overview of the issues of air quality, diseases, extreme heat, and mental health  – supporteclimate-video.pngd by more detailed  articles – for example,  Climate Change, Air Quality, and Public Health ;  Wildfire Smoke and Health ; and a new 4-minutes video about wildfires, with impactful images which highlight the links between wildfires and mental health,  especially relating to first responders and medical providers.  The Prairie Climate Centre also published the Heat Waves and Health  report, released in August 2019, and now part of the new section.

2019 Lancet Countdown emphasizes climate impacts on children’s health

lancet childrenSince 2016, the prestigious medical journal The Lancet has published an annual report,  Countdown  on Health and Climate Change  .  The 2018 Countdown report focused on  work-related health impacts of climate change, especially heat effects, as summarized in the WCR here . The 2019 edition  just released in early November focuses on the impacts of climate change on the health of children, with this key message: it is possible to limit the global average temperature rise to well below 2ºC, a situation which “would transform the health of a child born today for the better, throughout their lives. Placing health at the centre of the coming transition will yield enormous dividends for the public and the economy, with cleaner air, safer cities, and healthier diets.”

In addition to the global report, the Lancet also publishes country-specific Policy Briefing reports.  The Policy Briefing for Canada  (in French here ) is written in cooperation with the Canadian Medical Association and the Canadian Public Health Association.  The four highlighted results for Canada are:

  1.  “Exposure to wildfires is increasing in Canada, with more than half of the 448,444 Canadians evacuated due to wildfires between 1980 and 2017 displaced in the last decade; lancet wildfires
  2. The percentage of fossil fuels powering transport in Canada remains high, though electricity and biofuels are gaining ground. Fine particulate air pollution generated by transportation killed 1063 Canadians in 2015, resulting in a loss of economic welfare for Canadians valued at approximately $8 billion dollars;
  3. Canada has the third-highest per capita greenhouse gas emissions from healthcare in the world, with healthcare accounting for approximately 4% of the country’s total emissions;
  4. The health of Canadians is at risk due to multiple and varied risks of climate change…… An ongoing, coordinated, consistent and pan-Canadian effort to track, report, and create healthy change is required.”

For each of the four problems, broad policy recommendations are made.

Some of the other countries for which Policy Briefs are available: Australia ;  European Union ; the United Kingdom ; and the United States . Each one reflects the unique challenges of the country concerned.  The full menu of all Country Briefs is here.

The Summer of 2019: Flooding, hurricanes, wildfires and heatwaves

The world has awoken to the real-life manifestations of climate change in 2019, and we have been bombarded with media images of extreme weather disasters.  July 2019 was approximately 1.2°C warmer than the pre-industrial era, according to a summary of international heat waves by the World Metorological Organization (WMO) on August 1.  The WMO also published “Unprecedented wildfires in the Arctic” (July 29) and “Widespread fires harm global climate, environment” on August 29, including information about the Amazon wildfires.   “Global heating made Hurricane Dorian bigger, wetter – and more deadly”  by scientists Michael Mann and Andrew Dessler appeared in The Guardian on September 4  and “Is climate change making hurricanes stall?” at the PBS website  both offer clear summaries of  the climate change connection to the most recent extreme weather disaster the world has seen.

In Canada, flooding was the predominant weather disaster: In a July 2019 press release, the Insurance Bureau of Canada  described the flooding events of April and May and estimated that spring flooding in Ontario, Quebec and New Brunswick caused close to $208 million in insured damage . In the same press release, the IBC advocates that all political parties in the upcoming federal election commit to a National Action Plan on Flooding.  ( The IBC  published Options for Managing the Flood Costs of Canada’s Highest-risk Residential Properties in June,  the result of national consultations with the  Working Group on the Financial Management of Flood Risk, co-chaired by Public Safety Canada and the IBC.  The report is summarized in the IBC press release  and in the National Observer  “Who should bear the financial risk of flooding? Report lays out three options” in the National Observer June 19 .  )

BCclimate-risk-assessmentIn what it calls the first report of its kind in Canada to examine climate risks at the provincial level, the British Columbia government published a Preliminary Strategic Climate Risk Assessment for British Columbia in July 2019. The report evaluates the likelihood of  15 climate risk events and considers their health, social, economic and environmental consequences, concluding that the greatest risks to B.C. are severe wildfire season, seasonal water shortage, heat wave, ocean acidification, glacier loss, and long-term water shortage.  A compilation of  forty-six articles concerning Wildfires is available from the National Observer, and includes “‘Climate change in action:’ Scientist says fires in Alberta linked to climate change” (June 10).

In late June, Healthy Climate, Healthy New Brunswickers: A proposal for New Brunswick that cuts pollution and protects health was released, written  by Louise Comeau and Daniel Nunes. The report describes how climate change will affect the physical and mental health of all New Brunswickers, especially children, seniors, the isolated, and those living on low incomes. The report combines climate projections and existing community health profiles for 16 New Brunswick communities, emphasizing the risks of more intense precipitation, flooding and heat waves.

Extreme Heat in Canada and Beyond: 

heatreportcoverThe Prairie Climate Centre at the University  of Winnipeg released Heat Waves and Health  in August – a brief and practical guide to the health impacts of heat waves, drought and wildfires in Canada. The report predicts future heat waves in Canada, based on data newly updated the Climate Atlas of Canada   .  Previous projections were published as Chapter 4 in the federal government’s 2019 report Canada’s Changing Climate Report :  “Changes in Temperature and Precipitation Across Canada” .

Heat is a much more widespread danger in the United States, with Phoenix Arizona experiencing 128 days at or above 100 degrees Fahrenheit in 2018 –  one of the hottest and fastest-warming cities in the country, according to an article in the New York Times,  “As Phoenix heats up, the night comes alive” . The Times article describes how citizens and workers must re-schedule their lives and their job duties to avoid the killing heat of the day.  Phoenix is also the main focus of a lengthly  article,  “Can we survive extreme heat” in the Rolling Stone (Aug. 27) .

killer-heat-report-cover-thumbnailKiller Heat in the United States: Climate Choices and the Future of Dangerously Hot Days   was released in July by the  Union of Concerned Scientists, directed to a non-technical audience, and includes interactive maps and downloadable date here . The report offers national and regional projections and in Chapter 5, addresses the particular implications for outdoor workers, as well as city and rural dwellers, and those in low-income neighbourhoods. A more technical version of the research appeared as “Increased frequency of and population exposure to extreme heat index days in the United States during the 21st century” in the Open Access journal Environmental Research Communications .

The accuracy and sensitivity of occupational exposure limits to heat is examined in “Actual and simulated weather data to evaluate wet bulb globe temperature and heat index as alerts for occupational heat related illness”. This important article, published in the  Journal of Occupational and Environmental Hygiene in January 2019, analysed the cases of  234 outdoor work-related heat-related illnesses reported to the U.S. Occupational Safety and Health Administration in 2016 and concluded that wet bulb globe temperature (WBGT) should be used for workplace heat hazard assessment. When WBGT is unavailable, a Heat Index alert threshold of approximately 80 °F (26.7 °C) could identify potentially hazardous workplace environmental heat.

Finally, “Can the Paris Climate Goals Save Lives? Yes, a Lot of Them, Researchers Say” in the New York Times (June 5)  summarizes a more technical article which appeared in the journal Sciences Advances on June 5 .  “Increasing mitigation ambition to meet the Paris Agreement’s temperature goal avoids substantial heat-related mortality in U.S. cities”  reviews the literature about heat-related mortality and concludes that achieving the 1.5°C threshold of the Paris Agreement  could avoid between 110 and 2720 annual heat-related deaths in 15 U.S. cities.

New Brunswick launches consultation on industrial emissions – updated

The Government of New Brunswick opposes the federal government carbon tax and maintains a “We can’t afford a carbon tax” page on the government website – which estimates the costs (but none of the benefits) of the federal carbon backstop in effect in the province.  On June 13, New Brunswick introduced its own Made-in-New Brunswick  Regulatory Approach for Large Emitters ,  an output-based pricing system which will cover roughly 50 per cent of greenhouse gas emissions in the province and will require large industrial emitters, including electricity generators, to reduce their greenhouse gas emissions intensity by 10 per cent by 2030.

The CBC summarized the plan and reaction in “Province proposes carbon tax on tiny fraction of emissions from big industrial polluters”  (June 13) . CBC states that the proposed system would tax only 0.84 percent of greenhouse gas emissions from the province’s biggest emitters, such as Irving Oil,  far below the 20 per cent in the existing federal system. However, it covers the same industrial sectors, applies to the same gases and applies the same price scale of $20 per tonne this year, rising to $50 per tonne in 2022.

A Discussion paper , Holding Large Emitters Accountable: New Brunswick’s Output-Based Pricing System  forms the basis of a public comment period about the proposed system, which runs from June 13 to July 12.  One public response has been published by the Ecofiscal Commission in Exception to the Rule: Why New Brunswick’s Industrial Carbon Pricing System is Problematic (June 19) , which contends that under the proposed regulations, “firms can very easily achieve their emissions intensity benchmark, because it will be essentially set to current levels.”

The Conservation Council of New Brunswick reaction was quoted by the CBC, and also states that the proposed regulations are too weak.  Emphasizing the importance of the issue, on June 25 the Council released Healthy Climate, Healthy New Brunswickers: A proposal for New Brunswick that cuts pollution and protects health,  by Louise Comeau and Daniel Nunes. The Council characterizes the report as “the first comprehensive look at how climate change will affect the physical and mental health of all New Brunswickers, but particularly the very young, seniors, the isolated, and those living on low incomes.”  The report combines climate projections and existing community health profiles for 16 New Brunswick communities, emphasizing the risks of more intense precipitation, flooding and heat waves. It includes recommendations for action and attempts to end on a hopeful note. The report is available in English and French versions from this link .

Updates on New Brunswick’s carbon tax:  On July 8, CBC reported “New Brunswick Premier Blaine  Higgs  abandons  planned carbon tax court fight” , which explains that the province will save taxpayers’ money by supporting Saskatchewan’s Supreme Court of Canada challenge to the carbon tax as an intervenor, since Saskatchewan’s arguments are the same as New Brunswick’s.   Also in  July, an historical and political analysis appeared in Policy Options, “ New Brunswick’s timid foray into carbon pricing”, as part of the week-long series , The Evolution of Carbon Pricing in the Provinces .

 

Canadian nurses’ unions issue a call for action on the climate health emergency

Nurses climatechange-cover-368x480The Canadian Federation of Nurses Unions (CFNU) is the umbrella organization representing approximately 200,000 nursing and front-line health professionals in unions across Canada. At their Biennial Convention in Fredricton in June, representatives passed Resolution #3, calling on the CFNU and its Member Organizations: …  to recognize within their position statements that climate change is “a global crisis and health emergency”; …to support sustainable health care practices to reduce greenhouse gas emissions in health care settings; …to “engage with community stakeholders, such as the Canadian Labour Congress, in initiatives and campaigns that raise the public’s awareness about the serious health implications of climate change”; and to call on the federal and provincial governments to undertake the necessary policies to meet Canada’s obligations under the United Nations Framework Convention on Climate Change (the Paris Agreement)….”

Also at the convention, the CFNU released a  discussion paper: Climate Change and Health: It’s Time for Nurses to Act . It is described as “a starting point for for advocacy and leadership”. It summarizes the well-established health impacts related to climate change in the Canadian environment – for example, heat stress, increased allergies and asthma, cardiorespiratory distress from air pollution due to wildfires, Lyme disease. It includes a special focus on mental health and anxiety impacts.  It also highlights three practical examples from  2018 : wildfire smoke exposure in B.C., flooding in Atlantic Canada, and heat waves in Ontario and Quebec.

The report concludes with these six recommendations for nurses:

  1. Work with your employers, unions and associations to reduce emissions and to “green” your workplace.  (sub-recommendations include “Promote the divestment of pension plans from high-emission sectors and the investment in clean technologies and low-emission sectors;”)
  2. Know about climate change science, and help educate patients and the general public about it.  (sub-recommendations include “Campaign for the ecological determinants of health to be included in nursing education to prepare future generations of nurses, who will see the greatest effects of climate change. Nursing education should support a basic level of climate change literacy.”)
  3. Call for meaningful federal and provincial actions to reduce and eliminate climate change-causing emissions to ensure Canada leads the world in implementing its obligations under the UN Framework Convention on Climate Change (The Paris Accord). (Sub-recommendation: Promote transitioning away from fossil fuels towards renewable energy. ….. By investing in renewal energy rather than in fossil fuels we are committing to a healthier future.)
  4. Be aware and plan for the emerging needs of patients resulting from climate change and help them take action to support a healthy planet. (Sub-recommendation: “ Be aware and prepare your workplaces for future influxes of climate refugees coming to Canada. This population may have experienced trauma or extreme environmental conditions and taken risks to enter this country.”)
  5. Be prepared for extreme weather events.
  6. Promote active transportation and local healthy agriculture and food systems to reduce emissions.

Climate-Change-Toolkit-for-Health-Professionals-2019-234x300The Discussion paper was launched as part of a panel which included Dr. Courtney Howard, president of the Canadian Association of Physicians for the Environment.  CAPE issued their latest Call to Action  in February 2019 , in collaboration with the Canadian Medical Association , the Canadian Nurses Association, the Urban Public Health Network , and the Canadian Public Health Association.  On April 30, CAPE released a Climate Change Toolkit for Health Professionals, which is available for download in either English or French , and offers eight stand-alone modules with seven factsheets. Topics include Climate Change Health Impacts Globally and Across Canada; Taking Climate Change Action at Health Facilities ; Preparing for Climate Change in our Communities;  and Engaging in Climate Change as Health Professionals, which highlights, for example,  CAPE’s role in the campaign to phase-out coal in Alberta. As part of their active advocacy campaign, CAPE  makes frequent media statements and was part of the health delegation which met with the federal Minister of Health on June 7 .
