A Brief Look at Climate Change - 669 Words

The global climate system is complex and its response to future anthropogenic greenhouse gases and to climate change adaptation, is often poorly understood. Climate change is an area where modeling in the framework of complex adaptive systems can improve our knowledge both with respect to the internal structure and adaptive mechanisms of climate and our capacity for designing efficient climate adaptation policies. Modeling of these systems includes a dynamic system consisting of transition equations describing the evolution of state variables characterizing the natural system, such as CO2 concentrations in the upper and lower atmosphere and in the oceans, and state variables characterizing the economic systems, such as physical capital and knowledge. The complex adaptive character of the system implies that the dynamic system will be nonlinear and nonconvex, will allow for nonlinear feedbacks and multiple basins of attraction, will evolve both in the temporal and spatial dimension, a nd will be influenced by forward looking optimizing economic agents (Xepapadeas, 2010). Moreover, any rational policy choice must consider the uncertainty about the magnitude and timing of climate changes impact on economic productivity (Cai et al., 2013). The majority of the literature, including the recent U.S. Government Interagency Working Group on the Social Cost of Carbon (IWG, 2013) does not model the stochastic nature of the climate and economic systems. Recent work, such as that of CaiShow MoreRelatedA Brief Look at Climate Change1461 Words   |  6 PagesThere is no doubt that climate change is happening around the world. Climate change is occurring everywhere, but not everyone can see it. Some people fail to realize that climate change is happening because they aren’t aware of what it is. According to the Oxford Dictionary, it is â€Å"the change in global climate patterns are attributed largely to the increased levels of atmospheric carbon dioxide.† Carbon dioxide is accumulating in the air, which captures the sun’s heat. In return, the earth isRead MoreA Brief Look at Climate Change1838 Words   |  7 PagesClimate change continues to be one of the biggest issues in the world today, both politic ally and economically because it aggravates average increases in the global temperature and contributes to rising seawater levels around the world, posing serious threats to human life. A required immediate response from the government to rectify the climate change problem includes penalizing emissions of greenhouse gases (GHGs). Hence a carbon tax should be aimed at: lowering GHGs emissions by penalizing pollutersRead MoreClimate Change in Earth1381 Words   |  6 Pagesmy view, climate change is the most severe problem that we are facing today-more serious even than the threat of terrorism. (King, 2004) were the wise words of Chief Scientific Advisor to the United Kingdom Government. For decades two major topics have been discussed from scholars to mere regular individuals. Rich people, the less fortunate, people from Canada or people from the Middle East, these two topics affect everyone. Those two topics are: climate change and tourism. Climate change can be definedRead MoreBp and Oil Spill996 Words   |  4 PagesBP was the  ªrst of these companies to change from a reactive to a proactive climate strategy formulation. In 1996, it withdrew from the oppositional Global Climate Coalition (GCC), which was characterized as the most powerful lobby organization in climate policy.28 BP then accepted the climate change problem as diagnosed by the Intergovernmental Panel on Climate Change (IPCC) and gave its support to the Kyoto Protocol. In 1998 BP’s strategy formu- lation developed further in a proactive directionRead MoreHow Climate Change Is Inherently Flawed1230 Words   |  5 Pagesrenewed interest in the topic of climate change. In the 2016 Presidential election, the green party received over 1.2 million popular votes nationwide, when they usually receive only 100 thousand or so. With an increased interest in the topic of climate change, I feel it is necessary to provide factual data and projections on the path climate change will take to decrease misinformation. I proclaim the correct course of action to solve the problem of climate change is to do nothing. Almost every argumentRead MoreTaking a Look at Resilient Cities1778 Words   |  7 PagesResilient Cities is fairly simple, it identifies a problem that cities are subject to and offers possible solutions. Peak oil and climate change pose huge threats to cities in the near future. Many countries and cities have response plans for crises such as terrorism and natural disasters, but very few are equipped to handle the consequences of oil shortages or climate change disasters. Cities must adapt to this possibility by becoming resilient, or risk total collapse. In these one hundred and eighty-fourRead MorePollution Horticulture821 Words   |  4 Pagesindustry especially with the current economic climate(Hale, 2010). Organically grown plants are less guaranteed having a yield of 10-20% less on average than non organically grown(Leifert, 2010). another effect of pollution is climate change(Houghton, 2010). This undoubtedly will challenge commercial horticulture in a number of ways, firstly it will have a impact on irrigation(Jerry Knox et al, 2007).

What We Know About Climate Change by Kerry Emanuel aims to address this issue of Earth’s vulnerability head-on as it suggests the plausible causes for the undeniable planetary warming observed in the last century all the while proposing pragmatic solutions to discontinue the unnatural processes credited with the abnormal warming. Brimming with absorbing and educative statistics and facts, What We Know About Climate Change first choosesRead MoreGlobal Warming Is A Global Issue Essay1115 Words   |  5 Pagesbelieves that global warming is a real issue that must be addressed. The world is now at the step in which it must take action to combat climate change. In the push to do this, many countries report their carbon emissions. However, in reporting our carbon emissions, many people are jumping to conclusions by wrongly pointing at China as most responsible for climate change. A Reuters article from April 13, 2015 titled â€Å"China to surpass U.S. as top cause of modern global warming† talked about how ChinaRead MoreSeattle Times Report : Climate Change1266 Words   |  6 PagesSeattle Times Report: Climate-change effects are already apparent in NW Review by Laura Sanders INTRODUCTION Seattle Times reporter Sandi Doughton wrote an article about the impacts climate change is having and could potentially have in the future on the Pacific Northwest. The article outlines the findings in the third National Climate Assessment, published in 2014. The National Climate Assessment summarizes the impacts on climate change on the United States and is compiled by a team of more
