But if these variations are changed permanently or mean temperature of the world change, there will be serious and unpreventable affects on the world. This heating is called as a Global Warming. It has become familiar to many people have an idea about environment as one of the most important environmental problems of human being has never seen before. Governments of the world have already realized importance of the issue Global Warming. Some protocols have been implementing since 1972 with United Nations Framework Convention on Climate Change (FCCC) and some other countries climate change plans. China's situation, plans and adaptation on global warming are examined and criticized in coming paragraphs. According to scientists, emission of Greenhouse Gases (GHGs) some chemicals which trap heat in atmosphere causes Global Warming. Carbon dioxide is one of the most emitted greenhouse gases in the world and well absorbing heat radiation coming from surface of the earth. Many things can be listed for the reasons of emission of GHGs. The main reason of emission of carbon dioxide is burning fossil fuels such as coal and oil. China is the largest producer of greenhouse gases and the largest emitter of carbon dioxide (CO2). It produced 6.8 billion metric tons of carbon dioxide which is about 23 percent of the world's carbon dioxide generation every year......

Emissions Trading and Carbon Credit Accounting for Sustainable Energy Developmen

...Articles Emissions Trading and Carbon Credit Accounting for Sustainable Energy Development With Focus on India A. N. Sarkar Senior Professor (International Business), Asia-Pacific Institute of Management, New Delhi, India Abstract Global climate change is inextricably linked with the enhanced build-up of greenhouse gases. Emissions- trading in the form of carbon credits or CERs is opening up a new vista of trade opportunities with prospect for gradual reduction of emissions particularly by the developed nations under Annexure-I categories. Various national and international programmes undertaken by the government and voluntarily by the non-government agencies have positively impacted on progressive reduction of emissions in many parts of the world. The paper highlights the emerging issues linked to the modalities of emission-trading, together with scope for developing sound accounting procedures for trading carbon credits. Paper discusses the opportunities for developing a sound marketing system of carbon credits with built-in efficiency in transactions, accountability and transparency in reporting systems with focus on India. Paper also GMJ,VOL 4,ISSUE 1 & 2, JANUARY - DECEMBER 2010 underlines the need to comply with the Global Accounting Standards, Tax Planning, access to Multi-commodity Exchange Market, certification, verification and enforcement procedures for proper execution of emission-trading initiatives aimed at achieving carbon neutrality.

If Current Carbon Dioxide Emission Trends Continue, Shells of Marine Organisms Will Start Dissolving in Some Parts of the Ocean Sometime Around Mid-Century

...Geochemistry Pop Quiz 2 - 20/3/2013 Niall Smith - SF Earth Science 1) On what evidence is the statement “If current carbon dioxide emission trends continue, shells of marine organisms will start dissolving in some parts of the ocean sometime around mid-century” supported? Provide a short explanation and what you think are the two most relevant literature references illustrating your point. The scientific evidence which supports this statement originates from two distinct categorical sources - historical scientific evidence, and present day observations and corresponding scientific projections or estimates. The historical scientific evidence in question consists of observations of the fossil record around the time of the Cretaceous-Tertiary boundary mass extinction event (65MYA). There is an observed vacancy or gap of the presence of carbonate shells at the end of the Cretaceous period in the fossil record, that were hugely abundant during the Cretaceous. This coincides with a meteor hitting the Yucatan peninsula in Mexico and causing the renown mass extinction. The geology of this peninsula in Mexico is dominantly cretaceous chalk, and on impact, heat and pressure from the collision released large amounts of gaseous sulfurous compounds (Caldeira, 2007). The mixture of gas, soot, ash and dust released in this enormous impact blocked the sun for possibly up to several months and profoundly interrupted insolation - the incoming solar radiation. This caused the......

Definition and Explanation of the Problem of Energy

...Definition and Explanation of the Problem Fossil fuels are a source of non-renewable energy that is quickly being depleted. The discussion of the use of fossil fuels brings to attention many different views and opinions, many of which are incorporated into environmental issues and concerns. Scientists and environmentalists have had an increased interest involving the usage and reduction of fossil fuels. Fossil Fuels take thousands, if not millions, of years to form. The rate of consumer consumption versus the rate of production is so increasingly unbalanced, that fossil fuels are no longer a viable source of energy. The topic has become a recent concern; the more fossil fuels that are expended, the greater the depletion of non-renewable resources there is. The two are directly related; as the consumption of these fuels increases, the amount of fossil fuels declines at an even greater percentage. With the modernization of society comes an increased demand for energy. The only way to satisfy this demand is to create more energy, most of this energy resulting from the expense of fossil fuels. With this increase in the usage of energy from fossil fuels, the amount of carbon dioxide in the atmosphere has increased as well, approximately thirty-one percent since 1870. Furthermore, these fuels are detrimental to the planet. In fact, they are the largest emitters of greenhouse gases. The burning of fossil fuels adds up to six gigatons (one billion tons) of carbon to the atmosphere......

Logistics and Ghg Emissions

...The essay will discuss the concepts and the importance of logistics in our global word. It will then move to the recent climate change and its impact on our world with particular reference to logistics and GHG emissions relationship. The write up will follow up with the EPA and other agencies reactions and discuss the impact and the changes in the logistics management by the companies around the world. SUPPLY CHAIN MANAGEMENT Supply Chain Management refers to the flows of processes though which the goods are moved from the customer order to the acquisition of raw materials, supply, production, and distribution of the goods to the relevant customer. It basically refers to the management of the activities for the collections of raw materials to the production at the factories to the distribution of these goods. The manager must coordinate with all of these pieces in a cordial manner for the effective management of the supply chain (Mentzer, 2001). LOGISTICS MANAGEMENT Logistics Management is widely known concept in the global world. All companies rely on the logistics for the efficient flow of the goods and services. For Example: Industrial manufactures rely heavily on these logistics for the transportation of the mass-produced items. At the same time, the consumer goods manufactures want their goods to be delivered to the outlets and warehouses before the customer calls for it. Therefore, Logistics management has now evolved into one of the most important links in......

Global Warming

...GLOBAL WARMING Global warming simply put is the warming of the Earth including its atmosphere and oceans. Scientists have opposing viewpoints about why this may be happening. Some believe that it occurs naturally and is a part of a normal cycle over time and it is not significantly affected by human activities. Others believe that human activities have profound effects on the warming of the Earth. The global warming hypothesis originated back in 1896 when Svante Arrhenius, a Swedish chemist, developed a theory that carbon dioxide emissions from the burning of fossil fuels would cause global temperatures to rise by trapping excess heat in the earth’s atmosphere. He understood that the earth’s climate is heated by a process known as the greenhouse effect. About half of the solar radiation reaching the earth is reflected back into space. The remainder is absorbed by land masses and oceans, warming the earth’s surface and atmosphere. This warming process radiates energy, most of which passes through the atmosphere and back into space. However, small amounts of greenhouse gases like water vapor and carbon dioxide convert some of this energy to heat and either absorb it or reflect it back to the earth’s surface. These heat trapping gases work like a greenhouse – sunlight passes through, but a certain amount of radiated heat remains trapped. The greenhouse effect plays an important role in preventing the planet from entering a never-ending ice-age. Without...

Research Summary on Carbon Emissions

...Australia’s per capita carbon emissions against other countries. It also discusses the economic theory behind carbon emission reduction policies which are in place. An example of these policies is the current solar PV panel subsidy, which is further examined. Australia’s per capita carbon (CO2) emissions are amongst the highest in the world. Figure 1 illustrates when compared to other high income OECD countries, Australia’s CO2 emissions are higher than Germany, United States and United Kingdom, and are second to only Luxemburg. Figure 1 World Development Indicators & Global Development Finance (2008) Figure 1 also illustrates that over twenty out of thirty of these countries are below 10 metric tons of CO2 per capita compared to the dramatically high 18.5 tons from Australia. Additionally to this, according to the ABC (Clarke, 2009) Australia’s CO2 emissions are set to keep rising. Rising CO2 emissions are the result of increasing economic output of the Australian economy. These CO2 emissions have risen to a level which is not socially efficient, and is damaging to Australia’s economy; they have risen to a level resulting in global warming. The negative externality of the markets inability to produce efficient CO2 outputs and a lack of property rights for atmospheric pollution is described by Helm (2010, p. 183) as “one of the biggest market failures”. The emitter of these Greenhouse Gasses (GHG) will face little or no economic incentive to reduce emissions......

Carbon Dioxide in Ecosystems and Organisms

...Carbon Dioxide in Organisms and Ecosystems. Carbon forms the backbone of all organic molecules that make up the bodies of organisms; including carbohydrates, lipids and proteins. The carbon atoms that make up each organism have got there as a result of being part of another organism. Carbon isn’t just in animals, carbon is a fundamental atom found in every ecosystem. An ecosystem consists of abiotic and biotic features in a given area at a given time. The Carbon Cycle shows how carbon is passed up the food chain and is released back into the atmosphere by respiration of the various organisms in the ecosystem. Not all carbon is released in respiration; some carbon is released back into the atmosphere as a result of combustion. Combustion is increasing globally year on year, shifting the balance of carbon dioxide in the atmosphere. Carbon dioxide is a greenhouse gas. Increasing amounts of CO2 can lead to global warming. Recently data has been published by government officials, showing the steady increase in CO2 concentration over the past few years. www.co2now.org shows on a graph that in 1955 the concentration of carbon dioxide in the atmosphere was approximately 312 ppm. By 2015 it is excepted that the concentration will be approximately 395ppm. Global warming, as a result of increased carbon dioxide concentrations, can cause an endless amount of damage to ecosystems. For example – carbon dioxide itself will become a limiting factor. Every food chain begins with a......

Global Warming

...Jayadev Kakumanu 8/10/2013 EN 1420 Global warming is caused by carbon dioxide emissions from fossil fuel burning power plants, carbon dioxide emissions from burning gasoline for transportation, methane emissions from animals, agriculture such as rice paddies and from arctic sea beds. It is also caused by deforestation of tropical rain forests, and increase in usage of chemical fertilizers on croplands. This paper will examine the advantages and disadvantages of global warming as well as the preventative measures our society can take to stop the progress of global warming. And finally, decide whether global warming is a lie or a hoax. There are many disadvantages to global warming. Global warming spreads diseases, as northern countries warm, disease carrying insects migrate north, bringing plague and disease with them. Global warming also causes warmer waters, which means more hurricanes. Some areas of our planet will suffer serious droughts and heat waves. Africa will be hit the most with more severe droughts expected in Europe. There are also going to be economic consequences, hurricanes can cause billions of dollars in damage and diseases cost money to treat. Polar ice caps will melt. This melting of ice caps will raise sea levels. The melting will also throw the ecosystem out of balance. The ice caps are fresh water so when they melt they will make the ocean less salty. The rising temperatures will endanger the survival of several species. The ice caps are......

Carbon Dioxide

...Have you ever walked outside and felt like the air is different than normal? Do you feel claustrophobic? Furthermore, are changes in atmospheric composition and global climate the result of human activity or natural processes? There is much evidence backing up either side and showing that the change could be the result of both. However, because of many factors, I believe human activity is the cause of change in atmospheric composition and global climate. Human population, man-made processes, and deforestation have a great impact on atmospheric composition and global climate change. The first trace of human civilization was in Mesopotamia, in which we know had different cities. Historians estimate that there were about 96,000 people in these cities. The human population of the world is now seven billion and counting. Historical records show that in 1997 there were approximately 365,000 babies born everyday; 140,000 people die each day; this gives the world a natural increase of 220,000 people everyday. The increase in population obviously means a rise in human activities. Gradually over time, the Earth’s climate has changed and so has atmospheric composition. To clarify one thing that will be stated throughout: changes in atmospheric composition cause changes in climate. An increase in human activity causes more likelihood for change in the atmosphere. More people on Earth means more human activity. If there is more harmful (to the environment) activity there will be a......

Carbon

...Carbon Emissions Josie Williams Bethel University November 10, 2015 Instructor: Dr. Red Prudhon Abstract Our nation has taken a very important step in slowing the making and use of ozone-destroying chemicals. Some simple things the everyday Americans can do to prevent future damage to the ozone layer and better use or conservation of carbon emissions is to become more educated on how to better make use of the chemicals already present in the environment and not produce more harmful chemicals. There are some simple measures that can be taken by just influencing the ability of natural cures, like rain forest, to remove CO2 from the atmosphere. Carbon Emissions Carbon emissions is one of the main greenhouse gases, it is a colorless, odorless gas that is naturally emitted from the earth’s surface, and through human function, respiration, and plant function, photosynthesis. Carbon dioxide is release when we exhale and is used by plants as necessary part of photosynthesis, which produces glucose, carbohydrate that must be consumed by humans in order to have energy. Also from these natural processes, carbon dioxide is also emitted through the combustion or burning of fossil fuels such as coals, oils, and natural gas. This happens when vehicles are driven as well as when power plants and industrial plants are utilized. Combustion also called burning......
