However, the Paris Agreement is based on voluntary emission reduction pledges and there is no legal framework that can bind the members' voluntary pledges (UNFCCC, 2015). An official website of the United States government. The focus of this chapter will be to unpack Gardiner’s analysis and consider its implications with regard to our most recent global effort to systematically strategize addressing climate change: the Paris Agreement (hereafter COP21; COP21, 2015). As noted earlier, this uncertainty justifies more aggressive action to limit emissions and thereby help insure against the worst potential outcomes. The last time atmospheric concentrations of CO2 reached projected levels (doubling of preindustrial levels or about 550 ppm) coral reefs disappeared from the fossil record for one million years. Figure 3 shows impacts on per capita GDP based on a study of the GDP growth effects of warming, highlighting the relatively high per capita income reductions in Latin America, Africa, and South Asia (though higher-income countries would lose more absolute aggregate wealth and output because of their higher levels of economic activity). The study argues that the cost of Kyoto Protocol would far outweigh its benefits and its implementation would cost at least $150 billion a year. In almost every case, some of the future effects and costs are not entirely known or able to be quantified or monetized. Dennis Meadows believes that the world’s understanding of global climate change is still very limited. There is, of course, substantial uncertainty in these calculations. “Climate Change” The consequences of climate change arte expected to intensify in the future and emergency and community planners must include climate change in their risk and needs assessments in order to identify and implement risk reduction measures and to better prepare for future disasters events. Also, while policies can control the flow of emissions, what is of ultimate concern is the stock – the concentration of cumulative greenhouse gases in the atmosphere. As indicated earlier, cost-benefit analyses in various economic models lead to differing conclusions as to whether it is optimal to constrain temperature increases to 1.5°C or 2°C (Nordhaus 2007, 2016; Stern 2006).2 Fortunately, countries have been taking steps to combat climate change, referred to in figure E as “Current policy” (which includes policy commitments made prior to the 2015 Paris Agreement). Figure 9 shows each region’s priced emissions—including both implemented and planned (in 2020) carbon pricing—as a share of total global emissions. The SCC follows the time path from the Interagency Working Group report prepared during the Obama administration (Interagency Working Group on Social Cost of Carbon 2016). At present, the international community, to some extent, deifies climate change, exaggerating its threats and ignoring other environmental and global issues. Economic effects that are not readily measurable are excluded, as are costs incurred by countries other than the United States. Of the 21 COPs held through the end of 2015, major progresses were made in Kyoto, Japan, in 1998; Bali, Indonesia, in 2007; Copenhagen, Denmark, in 2009; Cancun, Mexico, in 2010; Durban, South Africa, in 2011; and Paris, France, in 2015. This distribution aligns roughly with the distribution of emissions, though the United States is an outlier: as discussed in the introduction, Europe has generated 33 percent of global CO2 emissions since 1850, the United States 25 percent, and China 13 percent (Ritchie and Roser 2017; authors’ calculations). In addition, if climate change has an impact on the growth rate (as opposed to the level) of output in each year, then the impacts could compound to be much larger in the future (Dell, Jones, and Olken 2012).3, The effects of climate change will not be shared evenly across the United States; places that are already struggling will tend to be hit the hardest. As such, emitters have an incentive to find the least cost way of achieving the regulatory requirement. Estimates of the social cost of carbon depend on a wide range of factors, including the projected biophysical impacts associated with an incremental ton of CO2 emissions, the monetized value of these impacts, and the discount rate applied to convert future monetized damages into current dollars.14 As of 2016, the Interagency Working Group on Social Cost of Carbon—a partnership of U.S. government agencies—reported a focal estimate of the social cost of carbon (SCC) at $51 (adjusted for inflation to 2018 dollars) per ton of CO2 (indicated by the dashed line in figure 8).15. The Durban Platform is an agreement among the parties of the Convention that they will launch a negotiation process for an agreeable international framework that is legally binding to all member countries of the UNFCCC and in which all members share mitigation responsibilities, which should be presented for adoption by the members at the conference scheduled in Paris, France, at the end of 2015. In such context, climate adaptation measures depend imperatively on the local knowledge of the territory, its geography, ecosystem services, and the priorities and features of the local communities directly affected by climate change impacts. (2019) find that annual GDP per capita reductions (as opposed to economic costs more broadly) could be between 1.0 and 2.8 percent under IPCC’s RCP 2.6, and under RCP 8.5 the range of losses could be between 6.7 and 14.3 percent. In the short term, this may cause some people’s concern and support for climate change to decline, but it will help reduce the blindness and one-sidedness in the international community in researching and coping with climate change in the long run and make relevant climate policies become more rational cost–benefit analysis rather than fear of the exaggerated dangers and even end of the world. The effects of climate change will … A carbon tax would have different effects on different groups of households. Pizer et. To assess proposals for a national U.S. carbon price, it is important to understand the size of the likely emissions reduction.
