It should be viewed as an initial step in examining the research on climate change and applying it in specific policy circumstances. Actions taken to reduce fossil fuel use can offer substantial benefits for human health (by reducing emissions of conventional air pollutants) and for national security (by reducing dependence on imported energy sources).6, The costs and benefits of different courses of action are generally not well known.Decision making often involves weighing the possible benefits and costs of one course of action against another. Climate change mitigation yields multiple benefits – or ‘co-benefits’ – in addition to the reduction of greenhouse gas emissions. Indeed, almost all consumer-based, industrial, and governmental activities require the consumption of fossil fuels, either directly or indirectly. Do you want to take a quick tour of the OpenBook's features? The costs of climate change for the economy and the society will be much higher than the costs of fighting climate change now. Most of these effects are negative and have devastating environmental, economic and social consequences. Climate models have been unable to simulate major known features of past climate such as … , Climate change will place further strain on Australia's water supply. Rural communities and farmers exposed to more frequent droughts and floods. Community organisations need to step up to their role in building organisations and communities that are resilient to extreme weather events and natural disasters so that these impacts can be minimised. This dependence evolved not only because fossil fuels were available at low market costs but also because their physical and chemical properties are well suited to particular uses: petroleum for transportation; natural gas as an industrial feedstock, for residential and commercial space heating, and more recently as a fuel for electric power generation; and coal for the generation of electricity and as a feedstock for some industrial processes. The people are not yet sufficiently prepared to cope with the current and future consequences of climate change. Non-OECD countries include developing, newly industrialized, and Eastern European and former Soviet countries. There is a growing body of evidence that climate change will have a disproportionate impact on people already experiencing poverty and disadvantage and will also increase poverty and inequality across the community. Many factors complicate and impede public understanding of climate change.12 Public understanding of climate change is important because public opinion underpins policy and because the public—as consumers, employers, and community members—can initiate, implement, and support actions to reduce GHG emissions and encourage adaptation. Accessed July 4, 2020. Tend to live in areas more likely to be adversely affected by direct climate impacts and have far less ability to move or make other necessary adjustments to their living arrangements; Are often less able to introduce measures to reduce their exposure to rising costs such as energy and water efficiency; and. Absent strong and sustained policy intervention, fossil fuels are projected to remain the nation’s primary source of energy for the foreseeable future. Disasters and emergencies can arise from a range of events (or hazards): The two terms, disaster and emergency, are often used interchangeably. To support the global climate agenda, the EU has adopted binding … To avoid the worst ravages of climate change, the world must transform society and the economy on an "unprecedented scale", the UN has said. As climate changes, crop production strategies must change too. However, they do have two distinct meanings. Do you enjoy reading reports from the Academies online for free? change have characteristics that make such analyses extremely challenging. The difficulty of developing sound strategies for responding to climate change, and of building public support for such strategies, stems in part from the inherent complexity of the issue. The New York Times. Climate change will damage economies, devastate populations, increase resource scarcity and dramatically impact the cost of doing business. But this can be misleading in the context of climate change because long-term change is difficult to detect against natural variability without sustained systematic measurement, and because judgments of varying phenomena are strongly influenced by memorable and recent extreme events.13, People use different types of “mental models” to understand complex phenomena, and some of the prevalent models used for understanding climate change are inconsistent with scientific knowledge. Climate change can affect human health in a variety of ways. MyNAP members SAVE 10% off online. The changing environment is expected to cause more heat stress, an increase in waterborne diseases, poor air quality, and diseases transmitted by insects and rodents. Intergovernmental Panel on Climate Change, Protecting human health and safety during extreme weather events: A national framework, Inequality in Australia: A nation divided, http://www.csiro.au/en/Research/OandA/Areas/Oceans-and-climate/Climate-change-information, Adapting the Community Sector for Climate Extremes, People on low incomes and people who are unemployed, People who are homeless or living in poor quality housing or the private rental market, Frail older people and those with chronic health conditions, Aboriginal and Torres Strait Islander people, People with a disability and their carers, Residents of places where extreme weather events such as cyclones, bushfires, storms and storm surges are likely to be more frequent or intense and. This needs to be a policy priority and included in the Government's UK Climate Change Risk Assessment. It will likewise require significant changes in consumer choices, travel behavior, and other individual and household-level decisions. This is because many aspects of an “overly ambitious” policy response could be reversed or otherwise addressed, if needed, through subsequent policy change, whereas adverse changes in the climate system are much more difficult (indeed, on the time scale of our lifetimes, may be impossible) to “undo.”. There are also significant time lags in human response systems. It also … Among the potential surprises that could be in store is that climate change turns out to be more manageable than. One project Monteleoni worked on uses machine learning algorithms to combine the predictions of the approximately 30 climate models used by the Intergovernmental Panel on Climate Change… More green jobs and lower costs. American Association for the Advancement of Science\"The scientific evidence is clear: global climate change caused by human activities is occurring now, and it is a growing threat to society.\" (2006)3 2. Show this book's table of contents, where you can jump to any chapter by name. Climate change caused by the emission of carbon dioxide and other greenhouse gases is one of the foremost global environment problems today. View our suggested citation for this chapter. For example, changes to the water cycle have an impact on hydropower, and warmer temperatures increase the energy demand for cooling in the summer, while decreasing the demand for heating in the winter. Waiting to act until all uncertainties are resolved, or until impacts of concern have become fully manifest, will likely mean it is too late to have any meaningful effect in mitigating many risks. Nevertheless, making major reductions in GHG emissions and preparing to adapt to the effects of climate change will require transformative changes, for instance, in how the country produces and uses energy (see Box 3.1), builds buildings and transportation infrastructure, and manages water and other natural resources. A … Nonetheless report by the Commonwealth Senate in 2013 stated that: “it is predicted that Australia will experience more heat waves, extreme fire weather, severe storms, and drought across southern parts of the continent. \"Observations throughout the world make it clear that climate change is occurring, and rigorous scientific research demonstrates that the greenhouse gases emitted by human activities are the primary driver.\" (2009)2 1. Costs for society and economy . Finally, while it may be possible to scale back or reverse many responses to climate change, it is difficult or impossible to "undo" climate change, once manifested. The committee’s judgment—that the environmental, economic, and humanitarian risks posed by climate change indicate a pressing need for substantial action to limit the magnitude of climate change and to prepare for adapting to its impacts—rests on numerous lines of argument alluded to in this chapter, including the following: a L. Clarke, J. Edmonds, V. Krey, R. Richels, S. Rose, and M. Tavoni, “International climate policy architectures: Overview of the EMF 22 International Scenarios” (Energy Economics 31(Supplement 2):S64-S81, 2009). Still others suggest that there will be substantial economic advantages in leading the development of new technologies to deal with climate change. Impacts of climate change sea levels could rise, covering low lying areas, in particular east England Scottish ski resorts may have to close due to lack of snow Most of these effects are negative and have devastating environmental, economic and social consequences. Disasters operate as a kind of lens, allowing society to perceive what was before its eyes all along. There will always be some uncertainty associated with modelling the complex relationships between agricultural yields and future climate scenarios. "Few Countries Are Pricing Carbon High Enough to Meet Climate Targets." CSIRO & Vureau of Meteorology (2015) State of the Climate 2014, Commonwealth of Australia, Canberra. This chapter summarizes the most universally accepted effects of climate change … We need to eat. Climate change is already having an impact on health: There has been an increase in the number of heat-related deaths in some regions and a decrease in cold-related deaths in others. When estimating the overall financial costs associated with extreme weather events, it is imperative that consideration is given to the significant costs arising from health impacts.". The many complex characteristics of climate change discussed here—which reach across scientific, political, economic, psychological, and other dimensions—are not problems that must be fully “solved” before one can move ahead with making choices and taking action to address climate change (see Box 3.2). Natural disasters and extreme weather events can cause injury, mental health issues, increased risk of infection, and … And what are the effects of climate change? a The material in this box was adapted from NRC, America’s Energy Future: Technology and Transformation: Summary Edition (Washington, D.C.: National Academies Press, 2009). Lack of certainty about the details of future climate change is not, however, a justification for inaction. In a world that exceeds 2 degrees of warming, Australia will endure more frequent and intense extreme weather events, including heatwaves. Climate change is just one of many interacting factors affecting humans and their environment. Climate change is already stressing many freshwater species by warming water temperatures, shifting streamflow regimes, increasing extreme events (e.g., floods, drought, wildfire), and facilitating species invasions. This increases the risk of heatwaves and of bushfires. . Catastrophic droughts simultaneously shattered human societies across the … Actions that are taken in response to climate change will also pose differing types of risks to different regions, sectors, and populations. An issue of particular concern is that much of the equipment and infrastructure that leads to GHG emissions (e.g., roads, vehicles, buildings, power plants) have lifetimes of decades. A U.S. strategy for responding to climate change must therefore include careful consideration of which information, incentives, and regulations (provided by which level of government) will most effectively engage and facilitate wise decision making by these multiple actors. PWC (2011) Protecting human health and safety during extreme weather events: A national framework. Finally, in the committee’s judgment, the risks associated with doing business as usual are a much greater concern than the risks associated with engaging in ambitious but measured response efforts. Community organisations need to step up to their role in building resilient communities and organisations in the face of disasters and emergencies so that these impacts can be minimised. Based on feedback from you, our users, we've made some improvements that make it easier than ever to read thousands of publications on our website. Decisions on actions to limit or adapt to climate. Making substantial emission reductions within the next few decades will require accelerating this turnover faster than projected business-as-usual rates.4. “Major Climate Report Describes a Strong Risk of Crisis as Early as 2040.” Accessed July 4, 2020. Both private and public sector decision makers face investment choices today that will affect the ability to limit emissions and to adapt to climate change for many years to come. Golf, of course, requires grass. Investing in a low-carbon society and economy could create up to 1.5 million additional jobs by 2020. Droughts are expected to become more frequent and severe in some parts of the country, with the CSIRO and Bureau of Meteorology projecting that rainfall could decrease by 20-30% in southern states by 2070. Devolution of responsibility under the localism agenda also needs to be undertaken with care in relation to climate change adaptation. Projecting future climate change requires understanding numerous linkages among human activities, greenhouse gas (GHG) emissions, changes in atmospheric composition, the response of the climate system, and impacts on human and natural systems. Due to uncertainties in climate sensitivity and other factors, one cannot say exactly how severe climate change and its impacts will be for any given level of atmospheric GHG concentrations. This literature identifies that the following groups will be first and worst affected by the full spectrum of climate change impacts including: increasingly frequent and intense extreme weather events, reduced air and water quality, vector, food and water-borne diseases, and increasing costs for essential goods and services caused by impacts to food supplies, utilities and infrastructure: This is because people living on low incomes, or who experience other forms of disadvantage: Given the already growing disparity in household wealth in Australia , a key risk from climate change is worsening inequality as people on low incomes struggle to meet the rising costs associated with adaptation. This may include warming temperatures or melting glaciers. The federal government can play a critical leadership role in setting policies that affect the actions of all parts of society. The effects of climate change span the physical environment, ecosystems and human societies. Our climate plays an important role in human societies and affects agriculture, ecosystems, our natural environment and our health. More Australians die each year during heatwaves than any other natural disaster, with older people, children and people with chronic health conditions or experiencing poverty at greatest risk . Others argue that the United States, as the country with largest historical share of GHG emissions and with one of the highest per capita GHG emission rates, has an ethical obligation to substantially reduce domestic emissions, even in the absence of commitments from other nations. Global and European commitment to action . U.S. media coverage sometimes presents aspects of climate change that are uncontroversial among the research community as being matters of serious scientific debate.16 Such factors likely play a role in the increasing polarization of public beliefs about climate change, along lines of political ideology, that has been observed in the United States.17, There will inevitably be additional risks and surprises. Not a MyNAP member yet? Climate change risk or vulnerability assessments are available for 21 European countries, but more information is still needed, particularly on the estimated benefits and costs of different adaptation options.
