and a host of other environmental woes, because increases in greenhouse gas emissions into the atmosphere from the burning of fossil fuels and deforestation trap heat that would otherwise escape from Earth which results in global warming; however, global warming may just be caused by natural occurrences, such as cosmic rays, the sun, volcanic activity and the ocean. The combustion of fossil fuels input enormous emissions of CO2 into the atmosphere causing the atmospheric CO2 levels to rise radically

where availability of power is uncertain. The use of diesel generators to ensure continuous power supply has the disadvantage of increasing the greenhouse gas emission and consequent enlargement of the carbon footprint which has a deleterious impact on the environment. While contribution of the telecommunications sector to the global carbon footprint is low compared to other sectors like transportation and construction, it nevertheless contributes a noteworthy share and increasingly so with growing

issue which is referred as “global warming”. That’s why the major part of the world comes together to discuss about what are the causes and which impact they have on the life on earth. More and more countries are joining the meeting to discuss about how to define new restrictions to prevent and slow down the global warming. The surface of the earth which is warming up is not without consequences. Indeed some negative effects of the global warming have a heavy impact such as the rise in sea levels,

MPF53 FINANCE “Review the proposed Carbon Pollution Reduction Scheme (CPRS) in Australia and critique its impact on financial management decisions” BY Xiao Nie Yang Song Date: 20th April 2010 Introduction In today’s society, all countries in the world will experience climate change in coming decades because of increasing carbon pollution (climate change 2007). In order to reduce the carbon pollution, ETS and CPRS will be proposed in the world wide and Australia

save is human energy and time because these machines use energy in the form of fossil fuels, which is made from large amounts of carbon. They were created when the organic remains of plants and animals were buried millions of years ago. Over time, heat and pressure changed the remains into coal, oil, and natural gas. When people burn fossil fuels, huge amounts of carbon dioxide and other gases are released into the atmosphere; which result in several changes to the make-up of the atmosphere. The most

average temperature many times in the geologic past before humans were present (Enger & Smith, 2013). Therefore, scientists initially tried to determine if the warming was a natural phenomenon or the result of human activity. Several gases such as carbon dioxide, chlorofluorocarbons, methane, and nitrous oxide are known as greenhouse gases because they let sunlight enter the atmosphere but slow the loss of heat from the Earth’s surface. Evidence of past climate change going back as far as 160,000

------------------------------------------------- The role of anthropogenic climate changes is a climate change that refers to the production of greenhouse gases emitted by human activity. By examining the polar ice cores, scientists are convinced that human activity has increased the proportion of greenhouse gases in the atmosphere; The Earth has a natural greenhouse effect where certain gases (known as greenhouse gases) in the atmosphere allow the sunlight to enter but absorb the heat radiation. Because these gases absorb
