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.

Global warming is a big problem for us, and there are things that we have done to cause it.
One of the biggest environmental impacts which is steadily increasing in severity due to fossil fuel usage is global warming. Global warming is mainly caused due to the trapping of heat in the atmosphere due to increased amounts of carbon dioxide. Because of the burning of fossil fuels, there has been a twenty five percent increase in the amount of carbon dioxide in the atmosphere over the last 150 years (Clean Energy). This increase over the years has caused the global average surface temperature to raise ...
Many negative impacts have resulted from global warming, but many positive changes have been made by humanity. There have been many ideas on what humans can do to improve on the green house gases and CO2 emissions we create and where it can lead us to. For example, reducing CO2 emissions have been giving many thoughts of what could cause the upraising of green house gases. One of the main sources is automobile emissions. The makers of Shell Gasoline Corporation, a Fortu...
It is now a well-documented scientific fact that both the 20th and 21st centuries have experienced a general trend in terms of global warming. Scientific research and evidence clearly indicate that the earth’s surface temperatures are gradually increasing. There have been a variety of theories pertaining to the fundamental causes of global warming. However, one of the outstanding beliefs is that human activities are distinctively responsible for global warming. Although this phenomenon is not experienced on all regions around the globe, the average temperatures on the globe have increased by 0.7°C since 1900 (Hansen et al., 2006).
Many of the scientists believe that earth is getting hotter, and the average temperature of earth is increasing each year due to the excessive burning of fuels on earth. The idea that the earth’s temperature is increasing is called global warming, and humans are the main cause of it. In spite of this theory, many believe that there is no global warming because the surface temperature has not increased steadily, but documents and researches show that global warming is real, and it is endangering lives of the animals on the earth.
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.
The earth like any body in space cools and warms until energy inputs from solar radiation and outputs from natural radiation are balanced. Greenhouse gases emitted into the atmosphere from human activities trap some of the energy radiating from the earth, increasing the temperature at which the earth creates energy balance. Based on a study by Intergovernmental Panel on Climate Change (IPCC) done in the early 1990s, approximately 65% of human induced greenhouse gases contributed to global warming. Over 80% of the increased atmospheric concentrations of harmful gases since the industrial revolution have been causes by industrial countries. Due to recent outsourcing and manufacturing market transfers, Asia and Latin America are regions where harmful emissi...
When we remove and burn fossil fuels such as coal or petroleum, we cause the release of carbon dioxide and other heat-trapping in the atmosphere. Clearing forests also releases large amounts of carbon dioxide; on top of that plants use carbon dioxide to grow. Worldwide deforestation means that we don’t have many trees to absorb the extras carbon dioxide. This means more carbon dioxide stays in the atmosphere, trapping more heat. Another cause is when companies release smoke. The people that most affect global warming are the Americans, because they use %26 of the world’s oil, they release %26 percent of nitrogen oxides and %22 of carbon dioxide.
Humans have caused global warming by doing many things but the main three are burning of fossil fuels and green house gas emission, deforestation, and excessive use of chemical fertilizers. Global warming is like a bad dream going worse.
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 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
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...
Department of Energy, vehicles that run on gasoline emit the equivalent of 11,435 pounds of carbon dioxide per year on average nationwide. For all-electric vehicles, this average drops to about 4,815 pounds of carbon dioxide per car, per year (Emissions). Based on these statistics, there are definitely measurable benefits that come from using cleaner energy sources for travel. Cars that run solely on electricity produce less than half the amount of emissions that vehicles that run on solely on gasoline do. While the use of only electric cars is not necessarily the best possible solution to the problem of inefficient travel methods on a widespread level, they do provide a good example of clean technology that has already been created and somewhat implemented into daily use. If these types of vehicles where used by the majority of the population, it is easy to see that amount of damage done to the environment by greenhouse gas emission would drastically decrease. Moreover, the type of technology used in electric cars could be expanded to use in aircraft as well to create hybrid aircraft that use electricity along with fuel as a power source, therefore decreasing the amount of fossil fuels they consume and the amount of carbon dioxide they release in emissions. Clearly, there is much room for improvement in the efficiency of vehicles and aircraft, but there needs to be a larger initiative to take action on this issue if we are to protect the
As we approach the future we are faced with many global problems. Most of these problems arise because we have caused them ourselves. We need to face these problems and find a solution. Global warming, although most often overlooked in importance, is a crucial problem of the future directly related to human activities. Global warming is caused by gases humans release into the atmosphere called anthropogenic gases and by deforestation. Anthropogenic gases include carbon dioxide, methane, chlorofluorocarbons (CFCs), hydrofl...
A main cause in the recent studies of global warming is the usage or aerosols. Aerosols are a substance enclosed under pressure and able to be released as a fine spray, typically by means of propellant gas. An aerosol can range from hairspray all the way to dust particles in the air. The new worries that are starting to show prominence in society today are the increase in carbon dioxide from t...
