Global warming is the increase in the average temperature of the Earth’s surface (Mastrandrea n. pag.). According to scientists, humans are the main cause of global warming. Scientists say global carbon dioxide emissions should be cut in half over the next fifty years or the effects may be irreversible (Eilperin n. pag.). The two main activities that humans do to contribute to global warming are burning fossil fuels and clearing land. Most of the fossil fuels come from burning in automobiles, factories and electric power plants which provide energy for houses and office buildings (McClure n. pag.). Continued global warming can cause harm to plants and animals that live in the sea and force plants and animals on land to move to new habitats. It could also change weather patterns that cause flooding, drought and an increase in damaging storms. Global warming could melt the polar ice caps enough to raise the sea level, and in certain parts of the world human disease could spread and crops being harvested could decline (Mastrandea n. pag.). Also, during photosynthesis, the process trees and other plants use to make food; they remove carbon dioxide from the atmosphere. Clearing the land contributes to an increase in carbon dioxide by decreasing the rate at which it is removed from the atmosphere during photosynthesis. Some scientists say that the increase in greenhouse gases does not make much of a difference in the temperature. They instead think that natural processes could have caused global warming. Those processes include the increase in the energy the sun emits. But most of climatologists believe that increase in the sun’s energy has only slightly contributed to global warming.

Global warming is an issue we are all pretty familiar with. It is the climate change that we, humans, are responsible for. The warming of the earth’s atmosphere is caused by the fossil fuels we burn, clearing of forests, and the carbon dioxide and other harmful gases we release into the air (Cunningham, Cunningham, 2009). There are other harmful toxins we use such as pesticides that are supporting global warming. Some effects of global warming include: increase in weather catastrophes, melting glaciers, rising sea levels, and the impact on species could lead to extinction (Cunningham, Cunningham, 2009). “Many scientists regard anthropogenic global climate change to be the most i...

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

Global warming is a phenomenon and impact of climate change. An average upward change in global temperature over a period, a few decades, is the impact of climate change caused by human actions. The deforestation, use of fossil fuels, emissions, and the likes cause such environmental changes as rising sea levels, enhanced atmospheric temperatures, and extreme weather conditions. Whether human actions are responsible for global warming is a controversy doing the rounds. The greenhouse effect which refers to retaining of a part of the sun's radiation in the earth's lower atmosphere leading to increasing in the earth's temperature is the cause of global warming. Also, depletion of the ozone layer is a major source of global warming. However, human actions in burning ...

Global warming, which is an increase in the average temperature of the earth, has many factors that have to be considered to what is the culprit in an increase in temperature. According to Utah researchers, Eldredge and Biek, the earth is currently in an ice age with temperatures colder than they have been throughout some of earth’s history. Going through cycles of above or below average temperatures is very normal for the earth as many different factors go into the temperature including ocean and atmospheric temperatures, volcanic eruptions, and the level of carbon dioxide in the atmosphere (Eldredge and Biek, 2010). Knowing that the earth goes through cycles of warm and cold weather makes it difficult to have a definitive answer of how much human activities actually contribute to the warming of the earth. With the amount of carbon Dioxide that humans emit into the atmosphere, almost all scientists agree that human activity is having a profound affect on global warming. Stanford researchers Lobell, schlenker, and Roberts present data showing an increase of .13 degrees Celsius every decade since 1950 with an expected increase in temperature per year due to carb...

Global warming has been a continuous controversy regarding whether humans are the primary cause for the destruction of our planet. By simply living, humans are contributing to the unceasing rise in temperature of the earth’s atmosphere predominantly created by the greenhouse effect. Greenhouse gases, such as carbon dioxide and methane, trap heat in the atmosphere. A mass amount of greenhouse gases develop from the burning of fossil fuels. However, deforestation, industrial processes and a few agricultural practices still transmit gases into the air. Climate scientists can agree that human activities add significantly to the levels of greenhouse gases, which is indeed the leading cause of global warming.
Pro & con arguments: “ Is Human Activity the Cause of Global Climate Change?” The
The world is getting hotter, and it is our fault! Global warming is the term given to the slow rise in the earth’s temperature over a long period of time, which happens when air polluting gasses like carbon dioxide and methane gases get trapped in the atmosphere making the atmosphere thick. The thick atmosphere prevents heat from escaping, which changes the earth’s temperature to a warmer climate. This warming has a negative impact on the earth and all that inhabit which makes it an environmental issue of global concern. While some may argue that global warming is not real, the earth is proving otherwise. Warmer temperatures are causing ice glaciers to melt, resulting in a rise in sea levels. Global warming is also causing a change in weather patterns, imposing devastating and unpredictable weather conditions on plants, animals, and humans. While global warming is caused partly by natural environmental occurrences out of our control, human activities are responsible the majority of global warming. The combustion of fossil fuels, chemical fertilizer use, methane emissions from factory farm animals, and deforestation are the main human activities that contribute to global warming.

One of the most substantial problems in the world today is global warming. This gradual warming of the earth is in occurrence at an extremely slow rate but it is happening. Many scientists believe that as human’s work and release greenhouse gases into the earth’s atmosphere, it can become dangerous for the long lasting life of humans and our environment. “Unless we take immediate action, the impacts of global warming will continue to intensify, grow ever more costly and damaging, and increasingly affect the entire planet - including you, your community, and your family” (“Global Warming Impacts”). Everyone should be knowledgeable about global warming and the dangers that it brings to our planet. This essay will examine
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
