Introduction: Being the newly emerging economies‚ the BASIC Group (Brazil‚ South Africa‚ India and China)‚ we recognize climate change and global warming and are willing to reduce our greenhouse gas emission in order to ensure that we are building a low-carbon economy and have a sustainable development for the future. In the next 100 years there will be an increase in average global temperature between 1.8 °C and 4.0 ºC. Moreover‚ the average sea level will rise between 0.18 m and 0.59 m. These

lot of bubbles in the water which tells us that some kind of a gas was created when the alka seltzer was put into the water. The next step was the hypothesize what that gas might be. That mystery gas created by the alka seltzer in water had a reaction with the BTB. Since the BTB solution was under the soda bottle dome‚ a reasonable conclusion is that the gas released by the alka seltzer had a reaction on the BTB solution. The mystery gas turned the BTB solution from blue to yellow. This same reaction

based on paleoclimate study. Introduction: It is often said that global warming is led by human activities. After the industrialization‚ the CO2 level has been rising extraordinarily in a few folds in such a short period of time. As CO2 is a greenhouse gas‚ it is generally believed that human is the killer of Earth’s climate and the weapon is the CO2 level. However‚ is this general believe true? Is CO2 the crucial factor to change global climate? Is global warming really a outcome caused by human

in Earth’s average surface temperature due to rising levels of greenhouse gases” (Conway). According the United States Environmental Protection Agency‚ “Gases that trap heat in the atmosphere are called greenhouse gases.” Greenhouse gases are broken down into four categories: carbon dioxide‚ methane‚ nitrous oxide‚ and fluorinated gases. Each category will be later looked at in further depth along with the three main factors each gas has on climate change. Changes in sea level‚ animal species

that have tried to make this agenda a priority but succeeded with no luck doing so. Some environmentalist has concluded a lot of the observed warming is most likely due to the burning of coal‚ oil‚ gas and other fossil fuels. This assumption was based on a detailed understanding of the atmospheric greenhouse effect and how human activities have been regulating it. During the same time‚ other reasonable explanations‚ most notably changes in the Sun‚ have been ruled out. The Earth could warm another 2

South Korea is a target country which will have to reduce the greenhouse gas since 2015. Therefore‚ this paper examines emission trading system in EU and China and it imply to South Korea. II. European Union (EU) In 2005‚ EU has enforced EU-ETS(European Union Emission Trading System) which is the first greenhouse gas emission system in the World. It is based on “Climate Change-Towards

Paleoclimatology is the study of prehistoric climates from evidence preserved in a wide range of geological settings. Paleoclimatologists study the evidence preserved in these geological settings‚ and search for the reasons behind climatic change throughout Earth’s history. By doing this‚ scientists may better predict future climate change and calculate the impact of humankind’s activities on the atmosphere and climate. Paleoclimatologists must piece together climatic history‚ but the further they

human activities rests on the following undisputed scientific facts: • Carbon dioxide (CO2) is a greenhouse gas that warms the atmosphere. • Since pre-industrial times‚ atmospheric CO2 concentrations have increased from about 280 parts per million (ppm) to over 380 ppm. Current concentrations of CO2 and other greenhouse gases are unprecedented in at least the last 650‚000 years‚ based on records from gas bubbles trapped in polar ice. • Independent measurements demonstrate that the increased CO2 in

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 concentrations 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 (Christianson‚ 1999). It is this foundation that fuels ours cognitive notion of global warming and the
