Global warming is the term used for an unequivocal and continuing rise in the average temperature of the Earth's climate system. Since 1971, 53% of the people in the U.S. have viewed global warming as a serious concern. I am with the 47% of the people that do not see global warming as a concern. A ton of companies are "going green" and my theory is that they are just doing it for the money. I think it is just a scam. There has been no such evidence that global warming has been caused by human activities. I believe that global warming is just earth going through a cycle and that it is not a concern or created by human activities.
Scientists have run many tests to figure out what is causing the Earth to rise in temperature. Greenhouse gases are thought as a reason for the Earth’s increase in temperature. The greenhouse effect is the process of absorption and emission of infared radiation by gases in a planet’s atmosphere warmth in its lower atmosphere and surface. Scientists have discovered that the major greenhouse gases are water vapor, which causes about 36-70% of the greenhouse affect; carbon dioxide, which causes 9-26%; methane, which causes 4-9%; and ozone which causes 3-7%. Scientists claim that human activity sin the Industrial Revolution has increases the amount of greenhouse gases in the atmosphere, leading to increased ozone, CFCs and nitrous oxide. In 2007, according to work published, the concentrations of carbon dioxide and methane have increased by 36% and 148% respectively since 1750. Over the last three decades, GDP per capita and population growth were the main drivers of increases in greenhouse gas emissions.

...ies that are “going green,” but in reality, they are just getting scammed into buying something for a higher price so that company can make more money. Considering that people have become gullible to the global warming fears, companies can put green or “going green” on their products and people will automatically buy their product, thinking that they are helping putting a stop to global warming.
I believe that global warming is just earth going through a cycle and that it is not a concern or created by human activities. Many scientists believe and have convinced people all over the world that global warming is caused by carbon dioxide release and harmful fossil fuels created by human activities. The same theory has convinced many people to get scammed by companies that are "going green." In my opinion, the external forcings theory appears to be the most logical.
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
According to Professor Mastrandrea the term global warming has been around for a long period of time. Back in the mid-1900s , humans were causing a lot of problems for climate change and none of that has changed since then , for example , starting fires or building gasoline engines. There are blueprints to global warming like, urgent deep reductions in carbon emissions, global reforestation efforts in semi-arid and drought affected regions and some of these have helped a diversity of nations but that doesn’t change the fact that global warming still occurs. All the unnecessary processes you can think of , have caused global warming , but people are still trying to prevent it (Mastrandrea).
It's no surprise to most people that the idea of global warming is a highly controversial and debated topic. But is there any real evidence that global warming is a growing problem or is global warming just a big scare tactic being used to get people to comply with strict government regulations? Global warming is widely believed to be the main cause of rising average global temperatures. In reality, global warming isn't really all what it has been exaggerated to be. Many of the predicted effects of global warming over time have actually been proven to be false all together.
Throughout history climates have drastically changed. There have been shifts from warm climates to the Ice Ages (Cunningham & Cunningham, 2009, p.204). Evidence suggests there have been at least a dozen abrupt climate changes throughout the history of the earth. There are a few suspected reasons for these past climate changes. One reason may be that asteroids hitting the earth and volcanic eruptions caused some of them. A further assumption is that 22-year solar magnetic cycles and 11-year sunspot cycles played a part in the changes. A further possibility is that a regular shifting in the angle of the moon orbiting earth causing changing tides and atmospheric circulation affects the global climate (Cunningham & Cunningham, 2009, p.205). Scientific studies suggest that all these played a role in past global warming and cooling periods. Today, however, there is a lot of conflict on whether humans are causing a global warming that could be disastrous to humans and all species of plants and animals on this earth. This paper will first explain the greenhouse effect, then take a look at both sides argument, and, finally, analyze the effect of global warming on world-wide sustainability
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
Earth’s climate is determined by the physics and chemistry of its atmosphere. Earth’s atmosphere consists of four layers; troposphere which is closest to earth, stratosphere, mesosphere, and thermosphere. Hardy says, “During the past 100 years we humans, as a result of burning coal, oil, and gas and clearing forests, have greatly changed the chemical composition of the thin atmospheric layer.” There is more carbon dioxide in the atmosphere due to burning fossil fuels. The atmosphere is made up of many gases such as nitrogen, oxygen, and argon. It also consists of trace gases such as carbon dioxide, methane, carbon monoxide, nitrogen oxides, chlorofluorocarbons and, ozone. The trace gases have the greatest effect on our climate (Hardy 5). Up to a certain level, these gases help to keep the planet warm by absorbing certain infrared wavelengths, so that there can be life on the planet. Thus, they trap heat in the troposphere and stop it from escaping to space (Hardy 7). Therefore, the greater amount of greenhouse gases, the more heat trapped in the atmosphere. Earth’s temperature is increasing due to increased levels of greenhouse gases such as carbon dioxide released into the air from burning fossil fuels. The Intergovernmental Panel on Climate Change (IPCC) 2001 report projects “global average surface temperature increases ranging from 1.4 to 5.8 degrees
Air pollution and greenhouse gases are the reason for the planet as it is today; the reason why we see campaigns flooding the media informing us to ‘switch off’, ‘save the planet’ and ‘turn down the heat’ and the reason why the government is trying to develop a successful scheme, such as the carbon tax scheme, to reduce air pollution caused by major industries. Air pollution and greenhouse gases are the two immediate causes of global warming and climate change. Air pollution occurs when chemicals or particulate matter enter the atmosphere. They can cause damage to living organisms on the planet, as well as destruction to the natural and synthetic environment (Energy Environment.net 2008). Greenhouse gases are gases in the atmosphere that absorb infrared radiation emitted from the earth. They trap infrared radiation in the form of heat, and hence contribute to global warming. Anthropogenic greenhouse gases are a direct result of air pollution. They are the physical gases emitted that cause air pollution. Naturally occurring greenhouse gases also have an influence on the earth’s atmosphere, though it is not as conspicuous as anthropogenic causes. Together, air pollution and greenhouse gases are intensifying climate change and global warming on a world-wide basis.
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 subject of global warming is as popular as the president. These both topics have always been hot subjects in everyday life. Global warming is the biggest storm headed in our way. It is also the most important issue of our times. Those ads or public service announcement on TV about global warming might not be the most attractive but the cause behind it is very important. Global warming is one of the major threats our planet is facing. Most scientists prove the fact that global warming is mainly caused by human activities rather than natural cycles. To simplify it, most mechanisms that we use are affecting earth. These mechanisms are created by humans. Therefore, humans are affecting earth.
Hello everyone! Today I will be speaking about global warming but before I begin, how many of you believe that global warming exists and that the human population is the primary cause of global warming? I ask this because there are people who believe that global warming does not exist or that it’s “a hoax created by China”. But that’s not true and global warming is in fact one of the biggest problems facing the world today. There is a significant amount of negative effects for the environment and for all living beings due to global warming. And maybe some of you are not be interested in global warming, but the truth is, global warming is a big part of our world and it affects each and every one of us.
Nature is something that no one can be 100 percent sure about and changes in any period of time. The earth’s temperature is dependent on the balance of the energy entering and leaving the planet. According to the EPA (Environmental Protection Agency), change in the planets orbit can lead to an increase on the climate on the planet. Nature also has an effect on climate change with external events, events that are not on the climate system. Volcanic eruptions and change in solar radiation are two of the external events that cause climate to change on earth. Although these two events cause the climate to change, they only have a short term effect (Canada). Islands and dry place are more common to have an increase in temperature because of the amount of energy that is generated and released back to the atmosphere. As the ozone is breaking down, the amount of solar energy being generated and released to the atmosphere is greater than before, which produces an increase on the world’s climate. Movement of crustal plates is also something that changes the climate on earth. The Northern Hemisphere usually gets warmer than the Southern Hemisphere due to the amount of land mass the Northern Hemisphere has. Around every eleven years, according to CSI, the amount of dark sunspots on the sun decrease from the maximum amount of sunspots to the minimum amount. Scientist call
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
Climate changes occur in our earth's atmosphere due to a buildup of greenhouse gases. Greenhouse gases can occur naturally as well as a result of human activities. The greenhouse gases are carbon dioxide, methane, and nitrous oxide. “Carbon dioxide is released into the atmosphere when solid waste, fossil fuels, and wood are burned.” (2) The gases help to warm the surface of the Earth. Each greenhouse gas absorbs heat differently. If natural gases did not occur, the temperature of the earth would be considerably cooler. “Problems can occur when higher concentrations of greenhouse gases are present in our atmosphere because they have enhanced our earth's heat trapping capability.” (3)
In conclusion, global warming is a slow and gradual process that is affecting our lives day by day. Some think of it as a myth, but now everybody can see and feel the climate change every year. Human beings are the prime cause of the global warming, so it is our responsibility to minimize it. Many environmentalists and nature protecting organizations such as the NRDC (Natural Resource Defense Council) have done various research on global warming and have come up with many ideas to prevent it. There are several creative ideas to stop global warming, and some of them have promises, for example, saving money while saving the environment.
Scientists blame the greenhouse gas effect in combination with societies greenhouse gas emissions for the rising temperature. The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions. Since part of this re-radiation is emitted back towards the earth’s surface and the lower atmosphere, it results in an elevation of the average surface temperature above what it would be in the absence of the gases (Intergovernmental Panel on Climate Change).
