Climate-related hazards can have significant implications for demand on health care services.
Impact on infrastructure
Storms, floods, wildfires, and extreme temperature events can create emergencies by damaging infrastructure and compromising access to critical resources.
Increased use of services due to health impacts
Poor air quality and increased risk of infectious diseases can result in more hospital visits, require additional resources, and increase waiting times.
Climate change could be the biggest global health threat of the 21st century. Effects on health of climate change will be felt by most populations in the next decades and put the lives and wellbeing of billions of people at increased risk. During this century, the earth's average surface temperature rises are likely to exceed the safe threshold of 2°C above pre-industrial average temperature. - The Lancet
"Climate change represents an inevitable, massive threat to global health that will likely eclipse the major known pandemics as the leading cause of death and disease in the 21st century ... The?health?of?the?world population must be elevated in this discussion from an afterthought to a central theme around which decision-makers construct rational, well informed action-orientated climate change strategies."
— Dr. Dana Hanson
President, World Medical Association
"The relationship between climate change and global health is unmistakable. This is a critical time for public health advocates to demand that political leaders safeguard the health of the world's population, with particular attention to the survival needs of the most disadvantaged."
— The International Response to Climate Change, An Agenda for Global Health Lindsay F. Wiley, JD, MPH; Lawrence?O.?Gostin, JD , JAMA. 2009;302(11):1218-1220
"As leaders of physicians across many countries, we call on doctors to demand that their politicians listen to the clear facts that have been identified in relation to climate change and act now to implement strategies that will benefit the health of communities worldwide."
— Taken from a letter published in the Lancet and the British Medical Journal, September 2009
A November 2014 report from the Intergovernmental Panel on Climate Change stated with high confidence that “Health impacts [of climate change] include greater likelihood of injury and death due to more intense heat waves and fires, increased risks from foodborne and waterborne diseases, and loss of work capacity and reduced labour productivity in vulnerable populations… Globally, the magnitude and severity of negative impacts will increasingly outweigh positive impacts.”
Increasing atmospheric and ocean temperatures bring with them increased frequency and severity of storms, epidemics, heat waves, and other natural disasters that can affect the health care system:
- Storms, floods, wildfires, and extreme temperature events can create emergencies by damaging infrastructure and compromising access to critical resources. Damaged hospital infrastructure or interrupted supply chain access can endanger?patients, visitors, and staff, and disable?care services when they are needed most.
- Warmer temperatures bring increased risk of food-, water-, and vectorborne infectious diseases.
- Increased emissions combined with extreme humidity can result in poor air quality, exacerbating respiratory conditions in vulnerable populations.
Climate Change in Canada
Canada's rate of warming is about twice the global rate: a 2°C increase globally means a 3 to 4oC increase for Canada. Effects will persist for centuries because greenhouse gases (GHGs) are long-lived and the oceans are warming. Cumulative CO2 emissions largely determine ultimate warming. A 2°C warming target may still be attainable, but we are already 65% of the way to the associated carbon limit or budget and global emissions must peak before mid-century. GHG emissions need to become net zero in order to stabilize climate at any temperature (NRCan).
Greenhouse gas (GHG) emissions in Canada are driven by a number of factors, such as economic and population growth as well as the mix of energy supply. Emissions in Canada’s commercial and residential buildings increased by 14 Mt between 1990 and 2005, and then remained relatively stable around the 2005 levels through to 2011. Since 1990 buildings have accounted for about 12% of Canada’s GHG emissions in any given year. The stability in emissions since 2005 is attributed mainly to energy retrofits, as 40% of all building floor space has seen some level of energy retrofit between 2005-2009.?
?Canadians across the country can be vulnerable to the health impacts of thunderstorms and lightning, snow storms, freezing rain, tornadoes, hurricanes, and hailstorms – particularly when widespread power outages occur and where health, social, and emergency services are insufficiently robust to handle large or concurrent events. -?Natural Resources Canada, 2014
Globally, the number of reported weather-related natural disasters is increasing. Climate change has driven extreme high temperatures and has probably contributed to more frequent and extreme precipitation events and more intense tropical cyclone activity. Together, these trends will increase the risk of weather-related hazards to human health. -?World Health Organization, 2011

Extreme heat events are an increasing concern in Canada and abroad. As the climate changes, the frequency, intensity and duration of these events are expected to increase, as are their related adverse health effects. In recent years, extreme heat has resulted in a significant number of preventable deaths. -?Health Canada, 2011
Extreme heat events pose serious health risks to Canadians; for example, they are associated with sudden, short-term increases in mortality, especially among older adults, people who are chronically ill, people on certain medications and the socially disadvantaged. A 2009 extreme heat event in British Columbia contributed to 156 excess deaths in the province’s lower mainland area and in 2010 an extreme heat event in Quebec resulted in an excess of 280 deaths. -?Natural Resources Canada, 2014
Climate change may affect health risks from both zoonoses and vector-borne diseases. Surveillance data indicates that Lyme vectors (as a proxy for Lyme disease risk) are spreading into Canada at a rate of 35-55 km per year and are following climate-determined geographic trajectories. -?Natural Resources Canada, 2014
Climatic factors like temperature and precipitation interacting with shifts in trade, travel, land use, and demographics are likely to affect the occurrence of vector-borne disease...around the world. Water-borne disease replication, survival, persistence, and transmission are subject to environmental influences and do best under warmer conditions such as those projected for the future. -?The Resource Innovation Group, 2012
Climate affects crop productivity, animal production, virility of pests and diseases, pollinator health and water availability and quality. Climate changes will necessitate changes in human activities (e.g. cropping systems, use of irrigation) and lead to flora and fauna reactions. -?Natural Resources Canada, 2014
Severe weather events and rising temperatures are likely to cause a decline in livestock productivity. Higher heat places stress on animals, which reduces dairy production and slows growth and conception rates. Marine fish population and distribution are already changing due to higher ocean temperatures. -?The Resource Innovation Group, 2012
Federal/Provincial/Territorial Working Groups
A?Pan?Canadian Framework on Clean Growth and Climate Change is in?progress. Provincial, territorial, and federal governments are working together to encourage clean economic growth, reduce greenhouse gas emissions, and prepare for the impacts of climate change.
The Working Group on Adaptation and Climate Resilience is one of four working groups established at the direction of Canadian First Ministers in the Vancouver Declaration. It is led by a federal and a provincial co-chair, and is composed of members from federal, provincial, and territorial governments.

Canada-Wide Coal Phase Out
Coal is a major contributor of greenhouse gas emissions, and talk is well underway to phase out its use in Canada.?
In May 2016, The Canadian Association of Physicians for the Environment (CAPE) blogged about Health Professionals Calling for an End for Coal. On September 2nd, a CAPE press release highlighted negotiations by several Canadian provinces to completely phase out coal plants by 2030.?
We will continue to post updates here as more information becomes available.

Eating too much red meat can have health consequences?and has negative impacts on the environment, causing air and water pollution that contribute to climate change. The James Beard Foundation?has developed an innovative strategy to reduce consumption of meat while still enjoying the foods we love: mixing in veggies. Enter?the Blended Burger. A blended burger combines mushrooms (or other plant-based ingredients) with ground beef (or other ground meat) to reduce the total meat in the burger while improving its flavor. Health Care Without Harm is bringing this strategy to the health sector as a complement to its “Less Meat, Better Meat” approach. Read More.
The Pan Canadian Framework on Climate Change and Clean Growth is now available online! Federal, provincial, and territorial governments have identified new actions to build resilience to climate change across Canada in the following areas:
- Translating scientific information and Traditional Knowledge into action
- Building climate resilience through infrastructure
- Protecting and improving human health and well-being
- Supporting particularly vulnerable regions
- Reducing climate-related hazards and disaster risks
The majority of Southeastern Australia hospitals were not designed with weather risks in mind, and many facilities in the region are currently feeling the impact of extreme heat. While healthcare providers are coping with the impact of the weather events, the buildings they work in and the infrastructure that supports them often constrain their ability to respond. Power outages and sick people waiting hours for beds have been reported. Read the article.

Climate change is a critical public health issue — one that hospitals need to do more to address. Every year, U.S. hospitals are emitting 8 percent of the nation’s greenhouse gases, generating more than 5.9 million tons of waste annually, and spending more than $6.5 billion on energy costs. While many hospitals are beginning to adopt more climate-friendly policies, including changing supply chains to obtain greener products, increasing water conservation efforts, or reducing toxic and hazardous waste, we still must do more to reduce our collective environmental footprint.

The?Notice of intent to inform stakeholders of upcoming consultations on proposed changes to the Greenhouse Gas Reporting Program, published on December 10, 2016, in Part I of the?Canada Gazette, provides information about the proposed changes and plans for consultations. The proposed expansion to the reporting requirements includes:
- Lowering the reporting threshold from 50,000?to 10,000 tonnes of carbon dioxide (CO2) equivalent. All facilities that emit the equivalent of 10,000 tonnes or more of greenhouse gases in CO2?equivalent per year will be required to submit a report;
- Reporting of additional data (e.g. more detailed emissions, quantities of fuels or feedstocks consumed, etc) and applying specific quantification methods to determine emissions. These new requirements will be gradually phased in by sectors.
ECCC will begin consultations with stakeholders in early 2017, in advance of issuing requirements for 2017. Interested stakeholders will find information on how to get involved in the above notice or on the?GHGRP website.?If you are interested in participating in a collective stakeholder discussion with the Canadian Coalition for Green Health Care, please email Linda at?linda@ดาวน์โหลดแอพเกมส์ยิงปลา www.centralevapeurguide.com.
The implementation notes show that the majority of the GHG emissions are within the supply chain providing products and services, and pharmaceuticals have been identified as a major GHG contributor to the health system – 16% of the entire NHS health care system carbon footprint. Also provided is a list of 20 priority pharmaceutical items with the highest GHG impact, which collectively account for more than 60% of the pharmaceutical footprint.? Having doctors understand the implications of medications from a global health perspective could be a small step in the education process and can start the discussion of what the options for reducing pharmaceutical use could look like.

A busy medical ward is the last place you want the lights to go out in the event of a hurricane, flood or extreme weather event. These are also the conditions that can drive surges of patients to emergency rooms for treatment at a rate that can quickly outpace the hospitals capacity to react. Climate change increases the frequency and magnitude of extreme weather events and conditions – from asthma to vector diseases — likely to increase demand for healthcare. Read more.
