Is Global Warming Man Made
There has been an ongoing debate about whether global warming is man-made, natural or if it even exists at all. The answer to that debate is that global warming is man-made and a direct result of pollution.
Carbon Dioxide, methane and nitrous oxide make up the biggest part of the cause of global warming, which form greenhouse gases. Greenhouse gases are trapped in the earth’s atmosphere and cause the earth to warm up. This temperature change has an effect on the earth’s ice, glaciers, oceans and ecosystems.
Carbon dioxide is a natural element in the earth’s atmosphere. At normal concentrations it along with other greenhouse gases helps maintain global temperatures at a level that is comfortable for humans and animals.

Burning fossil fuels such as coal, oil and natural gas releases carbon dioxide that has been stored underground for millions of years. Carbon dioxide is the gas responsible for the most warming in the atmosphere.
Methane gas is the second most important that make up the greenhouse gases. Methane is produced from the extraction, processing and distribution of oil, landfills and is released from the digestive systems of livestock. With humans increased red meat intake there is more demand for livestock which creates an increased output of methane.
Nitrous oxide is another part of the greenhouse gases that occurs naturally in the atmosphere. However, large amounts of released nitrous oxide contribute significantly to global warming. The sources of this gas are from fertilizers, gases used for refrigeration, industrial processes and motor vehicles which release nitrous oxide when operating with gasoline or diesel fuel.
Global warming started to become a factor in the 19th century with the industrial revolution. Since that time there has been a 20% increase in greenhouse gases in the last twenty years. However, nine of the warmest years on record have occurred in the last ten

Despite all the documented evidence of global warming, there are still those that believe that global warming does not exist. These skeptics are convinced that global warming was just a political platform used by Al Gore during his presidential campaign in 2000. One of the reasons Gore was criticized for his theory was because he made predictions associated with global warming that did not happen. For example he predicted that the Artic would be ice-free by 2013. He claimed the Pacific Islands were drowning and polar bears were dying.
Along with the Al Gore skeptics there are others that believe there is no significant increase in the earth’s temperature and that it’s just the liberals bulldozing anyone who tells you global warming is a
A greenhouse gas is any gaseous compound in the atmosphere that is capable of absorbing infrared radiation, thereby trapping and holding heat in the atmosphere. By increasing the heat in the atmosphere, greenhouse gases are responsible for the greenhouse effect, which ultimately leads to global warming. (EPA Environmental Protection Agency, 2014)
Greenhouse gas are a number of gases contributing to global warming which heat up the earth. The greenhouse gas that is emitted are carbon dioxide, methane , nitrous oxide and more. The greenhouse gases absorb infrared rays (heat) emitted from the Sun, which will be kept in the earth’s atmosphere rather that it being reflected away into space which helps the earth’s temperature to remain constant.
Carbon dioxide or CO2 is known to be one of a number of gases that are astonishingly transparent to the visible light that falls on the Earth from the Sun, but it absorb the infra-red radiation that emitted by the warm surface of our Earth, to prevents its loss into space. Moreover, CO2 has varied considerably and this affected the Earth’s temperature. Most common source of this CO2 is known as the fossil fuel. Fossil fuels are primarily coal, hydrocarbons, natural gas, or fuel oil that formed from the remains of the dead plants and also animals. The burning fossil fuel that has been created by humans is the largest source of emissions of the carbon dioxide.
Greenhouse gasses have a big impact on our atmosphere. These gasses include water vapor, methane, ozone, nitrous oxide, and carbon dioxide. Each greenhouse gas molecule has three or more atoms that are loosely held together and that eventually release the heat energy and it is absorbed by another greenhouse molecule. Many people talk about greenhouse gasses as if they are a bad idea, but they are not a bad thing. Without these gasses the earth would be zero degrees on the surface. However, too many greenhouse gasses can cause higher temperatures in the atmosphere, cause oceans to warm beyond what they should be normally and weather that is unpredictable. The same with fossil fuels that produce a variety of emissions that pollute our planet 's air and water. These pollutants threaten the environment and its
The Earth's climate has changed significantly throughout history. In the last 700,000 years there have been seven cycles of glacial advance and retreat. With the abrupt end of the last ice age approximately 7,000 years ago the beginning of the modern climate era was born. In the last century the global sea level has risen 17cm. All three major global surface temperature reconstructions show that Earth has warmed since 1880. Most of this warming has occurred since the 1970s, with the 20 warmest years, having occurred since 1981 and with all 10 of the warmest years occurring in the past 12 years. There is no denying global warming. Once considered a conspiracy theory by the world’s leading governments, industries and populations; global warming
The Earth’s current CO2 level is at 393.84ppm (CO2now, 2013). This is the highest of the high levels in the past 450,000 years. Extra carbon dioxide in the air is believed to keep temperatures steady and contributing to the greenhouse effect which causes the planet to warm. Scientists believe that humans add CO2 through the burning of fossil fuels, deforestation, and livestock farming to name a few. Natural processes also contribute to the CO2 emitted into the atmosphere including forest fires. Two sources on Earth remove CO2 from the atmosphere: Trees and the ocean. Deforestation can contribute to global warming because trees absorb carbon dioxide and when trees are removed the Earth loses its natural carbon storehouses. Phytoplankton consume CO2 through the photosynthesis process and transport it from the ocean’ surface to the deep. These sources eliminate 30-50% of carbon dioxide in the atmosphere.
I do believe that global warming is happening. The data that I have seen does suggest that there is a natural cause to global warming. There is also data I have seen that also supports the human cause of global warming. The amount of CO2 and other greenhouse gases humans are propelling into the atmosphere and into our oceans is un-natural. The balance is thrown off because of our use of fossil fuels and deforestation. It does not make sense to me for people to defend fossil fuels and delay new green alternatives, knowing they will run out in the future. Hendrickson and Sussman both seem to have cherry picked their facts they presented, making global warming seem like a hoax, but I don’t buy their arguments.
The main gasses that we recognize as 'greenhouse gasses' are carbon dioxide, methane, and nitrous oxide. Carbon dioxide, being the most well known, comes from a variety of places include natural causes and man made causes,
Some may notice that the weather is getting harsher with more frequent, large storms of all kinds. Some might say that it is nature trying to fight back for what is theirs. Others might blame these occurrences on global warming or climate change. Awareness has been raised about this issue more recently, but what is global warming? Global warming is the term used to describe the increasing of Earth 's average surface temperature over time (Johnson, R., 2009, p. 6). The greenhouse effect is a way of describing the science behind climate change. In the greenhouse effect, greenhouse gases such as carbon dioxide, methane, and nitrous oxide, get trapped under Earth 's atmosphere (Hynson, C., 2010, p. 42). Carbon dioxide is a gas that is produced by all living things when they breathe, as well as a waste product from fossil fuels (Hynson, C., 2010, p. 42). Although the main concerns about global warming are related to the rise of carbon dioxide, methane and nitrous oxide are increasing rapidly in the atmosphere as well. Methane traps 23 times as much heat as carbon dioxide does, while nitrous oxide is 300
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:
Secondly the amount of co2 we have relased into the air has caused global warming. Acording to ¨ Nobel Spaech by Al Gore, 70 million poultion that has caused global warming was released on the day of his speach. Futhermore ,Gore claims
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
Causes of climate change include longtime exposure of solar irradiance, human activity, and the greenhouse effect. The greenhouse effect is when the sun’s rays shine through the ozone layer and certain gases in the atmosphere don’t allow heat to escape the atmosphere. These gases forced to stay in the atmosphere are “forcing” climate change on the earth. The gases included the greenhouse effect include methane, carbon dioxide, water vapor, and nitrous oxide. This acts as a thermal energy blanket for the earth warming it beyond its point of a stable endpoint. The most abundant greenhouse gas is water vapor. Water vapor increases as the Earth’s atmosphere warms. Carbon dioxide is released through natural processes respiration and volcano eruptions and through human activities. A hydrocarbon gas produced both through natural sources and human activities, including the decomposition of wastes in landfills, agriculture, and especially rice cultivation, as well as ruminant digestion and manure management associated with domestic livestock. On a molecule-for-molecule basis, methane is a far more active greenhouse gas than carbon dioxide, but also one which is much less abundant in the atmosphere. A powerful greenhouse gas produced by soil cultivation practices, especially the use of commercial and organic fertilizers, fossil fuel combustion, nitric acid production, and biomass
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,
Global warming is the gradual rise in temperature and oceans due to recent human activity. This is created by the production of too much carbon dioxide that is released into the earth’s atmosphere. The carbon dioxide, also known as a greenhouse gas, remains in the air trapping heat and gradually warming the planet. Other greenhouse gases such as: methane, nitrous oxide, and water vapor also contribute to this slow warming. According to Live Science, The state of these gases being trapped is called the greenhouse effect, which is one of the leading causes of global warming (Lallanillia). All the gases are created differently and have different effects on the earth. As for some greenhouse gases can be in the atmosphere for a short amount of time, other gases can remain in the atmosphere for thousands of
