3Climate Change PolicyClimate Change PolicyIntroductionClimate change has become a pertinent issue in the world today. Climate change has been mainly in form of increased global temperatures, severe storms, and rising of the seal level. These poses a great risk in the existence of life on planet earth. According to studies, greenhouse gases are some of the primary causes of the changes in climatic conditions aroundthe world. This becomes a matter of even greater concern given that human activities are some of the major sources of greenhouse gases. Governments, economists, scientists, and other sector which are directly affected by global change being in the forefront in trying to figure out the problems which might be faced by the change in climate. One such action was by the UK government which created a committee led by Stern in 2006[ CITATION Ste06 \l 1033 ] to determine whether it was prudent for the government to spend some of its money to reduce the emission of greenhouse gases. This paper examines the need for curbing the emission of greenhouse gases and specifically CO2, in the light of the Stern report as examined by Kenneth J. Arrow (2011).Question 1The issue of reducing the amount of CO2 and other greenhouse gases have largely been controversial. Those against it saying that the costs incurred are high compared to the social benefit received. With the release of the Stern report, this matter became even more

Using a higher time preference value than stern and a η value of 2.1, Arrow examines whether the benefits of these costs are justified. Arrow, justifies that, the costs of mitigating the release of greenhouse gases is higher than the costs that the world will suffer in future due to an increased amount of CO2 in the air. Arrow further discusses the implications of failing to act and gives examples on how emission of green house gases couldbe reduced.Question 2The level of greenhouse gas emissions in the world are a major cause of the changes in global climatic conditions. Carbon II Oxide forms the largest part of the total global emissions.
