1. Introduction
Global warming has been generally concerned with the whole world. Over the past 100 years, the average temperatures of the Earth experienced 2 fluctuations which are cold-warm and cold-warm. However, the Fifth Assessment Report of Intergovernmental Panel on Climate Change (IPCC) points out that the average global temperature has increased 0.4 - 0.8°C in the overall trend. Even worse, scientists from the IPCC (2014) forecast the temperature will be higher and higher in the future.

The increase of greenhouse gas concentration happened nearly the same time as industrialisation through the 20th, when the worldwide human population started growing rapidly and farming also increased. Subjects of the stores and sources of these gases, both born and human induced, show than the main campaigns of the increasing concentrations are emissions from human actions (Australian Academy of Science, 2014). Human activities cause carbon dioxide input to the atmosphere from fossil fuel burning and deforestation. To this end, this report aims mainly to discuss the causes and effects of global warming and propound some suggestions to solve this issue.

2. The causes of global warming
2.1 Fossil fuels burning
One of the most significant causes of global warming is fossil fuels (coal, oil and gas) burning. According to Science (2013), the influence of recently fossil fuel use, even the most optimistic estimates suggest it will increase the temperature and affect the climate for tens of thousands of years.
Each time burn fossil fuels for the electricity of cars, air plane or plant can produce plenty of carbon dioxide. According to Head, Adams, McGregor and Toole (2014), around 20% of carbon dioxide emitted into the atmosphere co...

5. Recommendations
There are some measures for individuals and governments to take for reducing the effects of global warming.
 Government should create a joint research centre to develop clean energy sources. And people should try to use these clean energies such as solar power instead of using gas or natural gas.
 Government should build more public transports such as subway, bus and so on. Citizens should as many times as they can to use these to go to work or somewhere. It is best to ride a bicycle, not only reduce the exhaust gas emission but also has benefits on health.
 Humanity should plant as many as possible trees, the tree is the best way to protect atmosphere. Treasure to use a variety of paper in usual.
 Adaptation
 Government can establish carbon emissions trading system.

    We cannot dispute that automobiles, factories, and power plants, displace an unprecedented twenty tons of carbon monoxide - per person - per year. There needs to be a reduction in emissions, yet we cannot focus on this aspect of global warming alone. There are many indicators that climatic change is influencing the frequency and intensity of natural catastrophes. If scientific global climate models are accurate, the present problems will be magnified in the near future.

  • Importance Of Climate Change Essay

    1379 Words  | 3 Pages

    The emission of carbon dioxide has contributed to 80% to the heating of the earth atmosphere. Carbon dioxide is produced due the burning of fossil fuels such as natural gas, coal and oil. The burning of fossil fuel is very important in our society today, because it is used for cooking, used to produce electricity, for heating, for cooling and also for transportation. The industrialization has led to the use of fossil fuel for running machines and driving cars. The building of fossil fuel contributes towards 80-90% of the carbon dioxide we find in our atmosphere today. When the ecosystems are altered and vegetation is either burned or took out, the carbon stored in them is relinquished to the atmosphere as carbon dioxide (What causes global climate change, 2005). Methane is another gas being produced in the process which all have served to increase the greenhouse effect in our atmosphere. Methane is produced from the cultivation of rice, from the burning of coal and from cattle, it has increased by 145% due to human

    Pollution is a major problem for all of us. People need to recognize this situation so we can start making a difference to this problem. In order to start making a difference, the federal government should increase gasoline tax by one dollar a gallon. Fifty percent of this dollar will go towards public transportation, since passenger cars and trucks are a major contribution towards air pollution, according to the United States Environmental Protection Agency, E.P.A (10/4, http://www.epa.gov/autoemissions/emsns.html). Due to the expected increase after this is put forth, the remaining fifty percent of the dollar will go towards safety on these transits. When public transportation increases, air pollution will decrease, which will lessen the harmful health risks towards the environment.

    Global warming and global climate change is the study of future increases of temperature across the globe. Studying climate change refers to how the over- all climate will change such as the dry places getting dryer and the wet places getting wetter. Global climate is dependent on “the greenhouse effect a natural process that helps regulate temperature” (Easterling and Karl). In the past few centuries humans have had a monumental effect on increasing of greenhouse gases in the atmosphere. Climate change is result of the increase amount of the greenhouse gasses in the atmosphere such as methane, carbon dioxide, water vapor, nitrous oxide, and ozone. “Global temperature has rose approximately 1.4 degrees Fahrenheit over

    The climate on the Earth is changing. Ice age is interleaved with the global warming. In the present age, the temperature of the Earth's climate system continue rapidly increase and it leads to global warming. Global warming is the process of gradual growth of average annual temperature of the atmosphere of the Earth and World ocean. The average temperature on the Earth was increased by 0.6C. There are various reasons of global warming, such as human activities, natural events, increasing of gases, such as carbon dioxide in atmosphere and solar activity (Global warming). Nearly 200 countries have signed Kyoto Protocol and they must reduce four greenhouse gases, in order to struggle with global warming. There are several perspectives about effects of global warming on environment. In this essay will be considered the impacts and consequences of global warming . In the process, it will be clarified that there are positive and negative impacts of global warming.

    The article “an introduction to climate change” describes in detail about the causes of climate change, and its potential effect on earth. According to this article, the global warming is due to the accumulation of carbon dioxide and other pollutants formed from burning fossil fuels that accumulate on earth’s atmosphere so that light rays are reflected back to the earth surface causing the atmospheric air to heat up. In addition, the article also gives some relevant solutions to global warming such as reducing air pollution and use of “clean energy.”

    In talking about global warming, we need to learn what causes the greenhouse effect. Rays from the sun are taken up and absorbed by water vapor that is natural in the atmosphere. The United States emits the largest man made greenhouse gases in the world. As Americans we must realize the responsibility to reduce the emissions. (Gore, Albert) Water Vapor is eighty percent of greenhouse warming. The last twenty percent results from other gases that are in very little amounts. A huge absorber of the sun’s heat rays is carbon dioxide. Us as humans release a lot of carbon dioxide. When fossil fuels are burned, they release big amounts of carbon dioxide. Carbon dioxide is on the increase in our atmosphere due to car emissions. Approximately eighty percent of CO2 increases because of man’s use of fossil fuels. When there is more carbon dioxide in our atmosphere the more sun rays are absorbed. In result to this happening this will cause the earth and the earths atmosphere to warm. When the earth is warming, water temperatures will start to get warmer. Oceans and lakes will get warmer in result f...

    As Robert Frost once said, “ Some say the world will end in fire, some say in ice. From what I’ve tasted of desire I hold with those who favor fire.” This excerpt can relate to the idea of global warming. Global warming can be defined as an increase in the earth's average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect. During the past 10,000 years the earth has been in an ever-growing cycle that has significantly changed the climate. These changes are becoming more prevalent in our world today in the past 150 years. Scientists have been analyzing the causes and effects of the greenhouse effect and many other issues that global warming has presented. As John Houghton states in his book, Global Warming the Complete Briefing, on page 2 “ The 1980s and 1990s were unusually warm. Globally speaking, the decades have been the warmest since accurate records began somewhat over a hundred years ago and these unusually warm years are continuing into the twenty-first century.” There are countless records that show that our world as a whole is getting warmer, and the facts cannot be disputed. Everyone in the world today is experiencing the effects of global warming. These effects might be small now, but if we don’t protect our planet now then the consequences will greatly be increased.

    The burning of fossil fuels has greatly harmed our environment and is a leading cause as to why climate change has become such a threat to our way of living. In May of 2013, the carbon dioxide levels in the atmosphere reached 400 parts per million, an increase of more than 40 percent since the beginning of the Industrial Revolution. This could cause the Arctic Ocean to be nearly ice-free during the summer by 2020(Overland and Wang, 2013).

    Scientists, economists, and policy makers all agree the world is facing a threat from climate warming. Climate warming is caused by excess greenhouse gases such as carbon dioxide, which are heat trapping gases. Human use of fossil fuels is a significant source of these gases. When we drive our cars, heat our homes with oil or natural gas, or use electricity from coal-fired power plants, we contribute to global warming. Including any loss of trees or forests also contributes, considering trees convert carbon dioxide to oxygen.
