Whose responsibility is it to combat climate change?
In this study I am going to analyse how the different countries and individual people are responsible for combating climate change. I chose this topic because last year I’d studied about this topic and climate change is one of the main problems for last 3-5 years. From starting the earth people has caused several problems and climate change one of them. Now people should be the responsible about the damage they have made and try to find ways to fix. My country might be one of the victims of climate change on the future. That is another reason why I am interested about this topic. Definition of Climate Change

According to the Oxford English Dictionary, a climate change is “the change in global climate patterns apparent from the mid to late 20th century onwards, attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels”.

Our Earth is warming. Over the past century, Earth’s average temperature has risen by 1.4 °F and another 2 to 11.5°F rising up predicted over the next hundred years. Small changes; like those numbers in average temperature of the Earth can lead to large and potentially dangerous changes in climate and weather.

The evidence is clear. Increase on global temperature has been taken part by changes in climate and weather. Changes in rainfall is one of the obvious; changes in rainfall had impact on resulting in more floods, drought or intense rain in different places, as well as more frequent and severe heat waves. Oceans and glaciers have also faced some big changes – As the oceans are warming, they are becoming more acidic, glaciers are melting and the melted water from glaciers is leading to rise on sea level. As these and different changes become more well known through next several years, they will likely to have more affects on our society and environment. Global greenhouse gas emissions by sources

According to the Oxford English Dictionary, a greenhouse gas is “a gas that contributes to the greenhouse effect by absorbing infrared radiation, e.g., carbon dioxide and chlorofluorocarbons.” According to the following chart, taken from’s Different economic activities take part on global greenhouse gas emissions. Energy supply has the most influence (26%) on global greenhouse gas emission, burning coal, natural gas and oil for electricity and heat is the main reason high rate of energy supply. Industry covers the 19% of global greenhouse gas emission. Fossil fuels burned for energy main reason for global greenhouse gas emission from industry. However emissions from chemical, metallurgical, and mineral transformation processes are also another main factors and they aren’t relating with energy consumption. (Note: “Emissions from electricity use are excluded and are instead covered in the Energy Supply sector.”). Land Use, Land-Use Change, and Forestry are another main factor for global gas emission and cover 17%.  Carbon dioxide (CO2) emissions from deforestation, land clearing for agriculture, and fires or decay of peat soils are the main reasons for greenhouse gas emissions. Greenhouse gas emissions from agriculture mostly come from the management of agricultural soils, livestock, rice production, and biomass burning and agriculture takes part 14% on global greenhouse gas emission. Transportation is the next source and it has 13% influences on greenhouse gas emission. Fossil fuels burned for road, rail, air, and marine transportation are the main factors. Petroleum-based fuels, largely gasoline and diesel are used for 95% of world’s transportation energy. Waste and wastewater and Residential & commercial buildings are the last 2 sources and together they cover up 11% of greenhouse gas emission. Responsibility on Developed and Developing countries

Back in past, since the industrial revolution just started on beginning of the 21st century, developed countries were polluting...
