Global warming is an issue that threatens the world, but is often overlooked. This problem is an increase in the earth's temperature due to fossil fuels, industries, agricultural, and man-made causes. This results in the release of greenhouse gases. As climate changes occur in our earth's atmosphere buildup of greenhouse gases. There are many problems that are causing global warming, and if they are not taken serious or at least prevented there are going to be some severe issues in the near future.
Global warming has been caused by the people of the world. Pollution is one of the biggest problems caused by people. No one seems to realize is that by burning fossil fuels is one thing that causes pollution. Fossil fuels are fuels made of organic matter such as coal, or oil. When fossil fuels are burned they give off a green house gas called CO2. 40% of U.S. CO2 emissions come from electricity production, and burning coal accounts for 93% of emissions from the electric utility industry. As each day passes, we come up with a wide variety of new electrical devices.

Global warming is a scientific, political, and controversial topic. Some believe it is catastrophic, a slow moving killer hiding in the shadows. Others do not even think twice about it as they race by in a Hummer. Global warming is the gradual increase of temperature throughout different climates. It is caused by the greenhouse gas effect in which greenhouse gases, like methane and carbon dioxide, reflect sunlight back and forth. This reflected ultraviolet light bounces between the earth and the ozone layer and becomes trapped, resulting in a gradual rise of temperature. Over time, the slow rise of temperature causes new climates throughout the globe. The article “What Megablazes Tell Us About the Fiery Future of Climate Change” by Tim Dickinson
Firstly, global warming is said to be caused by the high levels of carbon dioxide released into the atmosphere by humans. Smoke produced by factories, vehicular exhaust, and the burning of fossil fuels such as coal in power plants are the primary sources of carbon dioxide. The theory is that carbon dioxide being released into the Earth's atmosphere is steadily building up because it cannot escape into space. The theory as to why the carbon dioxide in the atmosphere actually causes the Earth's average temperature to rise is outlined as follows:
Global warming is an increasing threat to the Earth and future generations. Global warming, sometimes called climate change, is the name given to the process of heat getting trapped in the atmosphere and damaging the environment. Greenhouse gases cause heat to gets stuck in the atmosphere by trapping the sun’s rays. When the sun’s rays enter the Earth, they should bounce back into the atmosphere. Instead the gases trap them, causing the temperature to rise. In the past the temperature of the Earth has risen slowly and evenly but recently the temperature has risen faster. The temperature of the Earth has risen at least one degree Fahrenheit during the twentieth century. If global warming is not controlled there are serious consequences. People, animals, and plants could be living in an atmosphere that is not suitable for sustaining healthy lives.
Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth's climate. While it changes the Earth’s climate it takes away different species that we depend on and some which other species depend on and also effect (in a bad way) the environment in which we live and can cause permanent damages to humans, animals, plant which will change the whole chain of ecosystem.
Nowadays, climate change is became a major global issue which are affecting our life such as global warming ,mean sea level changing and more extreme weather events etc .According to the research of Intergovernmental Panel on Climate Change 2007 ,it showed that the global mean temperature rose by 0.74 °C during the hundred year period from 1906 to 2005. Between 1956 and 2005,the rising rate was 0.13°C per decade in this 50 years , nearly twice the rate in the past 100 years. Eight (2010, 2005, 2003, 2007, 2006, 2009, 2012, 2004) of the last ten years (from 2003 to 2012) rank among the 10 warmest years on record. It seems that climate change is potentially affecting our life.In fact,human activities and natural effect are the causes of climate change.Generally,most of the scientists and government agree that human activities is the main causes of climate change rather than natural causes.Therefore,this essay is going to discuss why human activities change the climate more seriously than natural effect.Afterward,I will also present some possible solution to reduce the climate change.
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 continues to 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 oceans. The average temperature on the Earth was increased by 0.6C. There are various reasons for global warming, such as human activities, natural events, increasing of gases, such as carbon dioxide in atmosphere and solar activity (Global warming).
The commonly debated “greenhouse effect” refers to “the global average temperature increase that has been observed over the last one hundred years or more” (Spencer). President Barack Obama addressed the issue in an effort to highlight its severity, "We have to all shoulder the responsibility for keeping the planet habitable, or we’re going to suffer the consequences – together” (Leader). The earth’s increasing atmospheric and oceanic temperatures result in climate changes due to cumulative amounts of carbon dioxide (CO2) in the atmosphere. As an outcome, researchers around the globe have established that the by-product of burning fossil fuels is the main culprit of the increasing temperatures. Global carbon emissions from fossil fuels have significantly increased since 1900, as shown above from a study carried out by the Carbon Dioxide Information Analysis Center.
The most destructive human contribution to climate change is fossil fuels combustion, which results in the release of carbon dioxide and other greenhouse gases into the atmosphere. Increased carbon dioxide, methane, nitrous oxide and halocarbons levels in the atmosphere cause an imbalance in the earth’s energy. This is because the gases alter solar radiation and thermal radiation which regulate the earth’s energy. Research indicates that anthropogenic climate change is the cause of the increased global warming over the last fifty years. 57 % of the carbon dioxide emitted is absorbed into the atmosphere while the rest is absorbed into the oceans. Carbon dioxide in the atmosphere is the most central greenhouse gas that is associated with global warming (Eby, Zickfield, Montenegro, Archer, Meissner, & Weaver,
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...
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).
There needs to be a reduction if not extinction with the increasing amounts of carbon dioxide, methane, chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), per-fluorocarbons (PFCs) and nitrous oxide into the atmosphere because it is directly affecting global warming. The combustion of fossil fuels and greenhouse emissions mainly contribute to the increase of these gases. The longer we go without solving this global problem the more conflicts we will have in the future. Although global warming does make the earth warmer there is more to worry about than heating to death. Major concerns revolve around effects on agriculture, water resources, ocean level and coastal regions, and disease. Many scientists and experimenters still disagree with global warming using excuses such as ‘primitive’ climate models, which predict global warming trends, can not accurately simulate the Earth; it is too difficult because there are thousands of variables to consider. With the issue of global warming alternative sources of energy are looked for. “Data indicates that hydrogen is [the] only suitable future fuel.” (Williams, 102). Many scientists agree, but how long will it take for us to get there?
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.
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.
Global Warming is a condition caused by greenhouse gases and human activities. The increased concentration of greenhouse gases due to activities such as deforestation and fossil fuel burning is causing the Earth’s atmosphere and oceans to warm up. As a result of this, global warming has some serious effects in the shape of extreme weather, species extinctions, and rising sea levels. These effects can contribute to the changes that are taking place all over the world, most of which are dangerous enough to pose a threat to the survival of life on Earth in the future.
Global warming is an increase in average global temperatures. This will lead to rising temperatures of the oceans and the earth’s surface. Coal is a main contributor to global warming because so much electricity is produced from coal-burning power plants. According to the book Global Warming by Peggy Parks, “In the United States, more than 50 percent of all electrical plants use coal, which also provides power for about 40 percent of the total electricity generated throughout the world” (43). Global warming is also caused because of deforestation and the burning of fossil fuels. Many people say that global warming is natural; however, people speed up the process. Global Warming needs to be taken serious because as the temperature rises, it causes melting of polar ice caps, a rise in sea levels or unnatural patters of precipitation which can result in floods. This can also have an effect on wildlife such as the food chain. Many species have been dying of starvation and many have to move to different places due to the temperature changes. Possible solutions to Global Warming is for people to switch to LED light bulbs as it gives the same light and uses less electricity, wash clothes in cold water, buy less products, and to spread the
