Nursing’s Role in Climate Change Why is climate change an issue for nurses? • It is going to affect the health of the people we work with. • It is a social justice issue because the negative effects of climate change are felt most acutely by those who contribute to it the least. • We have the skills to make an impact in supporting people as they adapt to their changing climate. • We are well placed to support efforts to reduce GHG emissions. Overview • The objectives of this class are to: – provide an overview of the science of climate change – identify links between climate change and health – define adaptation to and mitigation of climate change – explore nursing’s role in supporting adaptation and mitigation activities – begin to identify potential policy responses Science of Climate Change Climate change Climate change is not just an environmental issue, as too many people still believe. It is an all-encompassing threat.

Climate change and social justice © Greenpeace Define Adaptation to and Mitigation of Climate Change Adaptation to climate change • Depends on: – Population density, level of economic development, food availability, income level and distribution, local environmental conditions, pre-existing health status, and the quality/availability of public health care • “No regrets” responses address these issues without making climate change the determining factor in decision-making • Planning for emergencies and heat waves © Her Majesty the Queen in Right of Canada, represented by the Minister of Health (2005) Mitigation of climate change • International agreements – Montreal Protocol on Substances that Deplete the Ozone Layer – Kyoto Protocol • Turning the Corner – Imposes mandatory targets on industry to reduce production of GHGs in half by 2015 – Regulates fuel efficiency of cars and light-duty trucks beginning 2011 – Strengthens energy efficiency of products – Different from Kyoto in that base year is 2006, not 1990 Canada’s GHG Emissions 1990-2005 Environment Canada, 2006 © Transport Canada: www.tc.gc.ca/road/vehiclesafety.htm © Environment Canada: www.ec.gc.ca/EnviroZine/english/issues/47/feature1_e.cfm Nursing’s Role in Adaptation to and Mitigation of Climate Change Examples of nursing roles • Adaptation – Emergency planning/preparedness • Involvement of nurses at all levels of government planning – Warning systems for heat waves • Through public health department with nursing support – Protective technologies • Sunscreen, air conditioning, urban planning, re-engineer water systems – Behaviour changes • Caution in hot weather, consider the Air Quality Index (AQI) in outdoor activities, be aware of changes in patterns of disease Examples of nursing roles cont’d • Mitigation – Energy-efficient homes, appliances and automobiles • List provided by World Wildlife Fund – Walking, cycling, transit to work • Improves cardiovascular health and reduces stress as well as GHGs – Urban planning to decrease commutes • Improves air quality and allows walking around community – Less travel for business • Invest in video-conference facilities – Eating local foods etc. Some policy debates • Absolute cap on emissions versus reducing their intensity • Carbon taxes to increase the costs of energy (and support reduced use) • Leadership by developed world versus BAU (Business As Usual) until developing world signs on to targets World Wildlife Fund (WWF): Activities to reduce GHG emissions At home: • • • • Switch to renewable energy. Eat local. Buy local. Adjust your thermostat. Buy energy-efficient appliances. Beyond your front door: • Drive less. • Don’t idle. At the office or at school: • Not using it? Turn it off. • Encourage others. For more tips, check the WWF website: http://www.wwf.ca/AboutWWF/WhatWeDo/ConservationPrograms/Global Warming/takeaction.asp Conclusions • Climate change has an impact on health, particularly in the developing world. • Nurses have a role in helping people adapt to their changing climate and reduce their GHG emissions. • What is needed is to increase our awareness and identify where we can make an impact. Courage my friends; ‘tis not too late to build a better world.
