Summary For Policymakers An Attempt to Save the Climate of the World

&nbsp.In the context of growing concern for global warming “Summary For Policymakers” is an attempt to save the environment from further disasters caused by global warming. During recent years the changes that are evidenced in the climate of the world, are a matter of great concern for the scientists and the common people of the world. The IPCC Fourth Assessment Report attempts to find out the ways of mitigation of climate change. For the sake of conveniences, the report renders various aspects of climate change, such as social, environmental, economic aspects, in order to accomplish the task of mitigation fruitfully. The report mainly focuses on the following topics: the trend in the emission of Greenhouse Gas, its mitigation in different terms, policies, and steps to prevent the change, and some other crucial factors that pose hinders in the way of the mitigation of climate change.

Studies show that emissions of Greenhouse Gas have increased seventy percent over the years from 1970 to 2004. Both man-made and natural factors are responsible for the increase of the emission of Greenhouse gas. Among the human activity related factors development of science and increasing use of technologies are the major factors that are the most responsible for the apparently abrupt growth rate of greenhouse gases- carbon dioxide, Methane, Nitrous Oxide, etc. “The emissions of these gases have increased at different rates” (IPCC, 2007, p. 3). In the study, a thing is remarkable that the emission of greenhouse gases was violent around the years from 1990 to 2004. During these years the violent emissions of Greenhouse gases occurred mainly in the energy supply sector. The emission rate is about 145 percent. The emission scenario is as follows: 120 percent from transport, from industry 65 percent, from& use 40 percent. But between 1970 and 1990 the emissions from agriculture and from the building are 27 percent and 26 percent
