Carbon dioxide is an important gas that is vital for plant life. This compound is made of a carbon atom and two oxygen atoms. Only 0.0397 of the atmosphere is composed of carbon dioxide. Even though carbon dioxide only makes up a small percentage of the atmosphere, lately increases in the amount carbon dioxide released into the atmosphere have shown to cause an adverse effect on the earth. The rise in amount of carbon dioxide in the atmosphere has caused the earth’s temperature to steadily rise. The term used to describe this effect is called global warming or climate change. Climate change is not something new. Over the past nine hundred thousand years the atmosphere has gone through extended periods of global warming and global cooling. These …show more content…
Earth’s temperature is greatly influenced by the amount of sunlight that reaches the earth, but recent studies have shown that the sun’s solar output has decreased in the past decades. Evidence to support this claim is that the troposphere (innermost layer of the atmosphere) has gotten warmer while the mesosphere (third layer of the atmosphere) has gotten cooler. If the sun was the only cause of global warming, the atmosphere would be getting hotter from top to bottom which is not the case because it’s getting hotter from bottom to top. The greenhouse effect also plays a key role in the Earth’s climate. The greenhouse effect occurs when solar radiation absorbed by the
Global Warming, much of what does or does not happen forty years from now rests on our actions or inactions taken between now and then. The crucial question is whether we should pour all our resources into mitigation – reducing our carbon emissions. According to scientists who study the climate there are other environmental problems; “we now face a global crises in land use and agriculture that could undermine the health, security, and sustainability of our civilization”.
Since measurements began in 1958 -- and it can be assumed to have been the case since the industrial revolution -- emission of carbon dioxide into the atmosphere has risen steadily as a result of the burning of fossil fuels (Quay, pp 2344). Although there is much argument over the implications of increasing carbon dioxide levels in the atmosphere, there are several points that almost all scientists would agree on: firstly, carbon dioxide acts to absorb radiated heat; if present in our atmosphere will do just that to some extent. Second, the concentration of carbon dioxide in our atmosphere is rising. Third, the temperature of the planet is rising - although the amount of this increase and the causes of this rise are subject to disagreement (Philander, pp 193).
When the sun heats the Earth gases are released as well as water vapor. They go into the atmosphere and regulate the temperature. This is known as global warming or the greenhouse effect. Many of the environmental complications derive from the political and social involvement. The climate was not the only cause, but we had humans played a role on what had been occurring to the world. Earth has many different atmospheric layers that are influenced by the greenhouse gases. “Atmospheric concentrations of carbon dioxide have now increased nearly 30 percent since the beginning of the Industrial Revolution; methane levels have more than doubled; and nitrous oxide concentrations have risen by about 15 percent” (Fagan 209). The increase of these gases also enhanced the trapping of the heat. With more heat being trapped this lead to many coastlines to flood due to the melting of snow and ice. The increase of dangerous weather actions will pose as a threat also. These changes in the environment would eventually lead to political and social change of the people Overpopulation in certain areas and industry formation influence the greenhouse effect. We as a whole are destroying the place we live, the natural world. Although there are ways to prevent and reduce global warming, we cannot stop the natural occurrence of future climate. Climate is not the only factor, each individual that as
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:
For a majority of people, it isn’t new news that the Earth’s climate is changing and increasingly getting warmer. For quite some time now, people have been arguing about what the actual causes are and what role humans have played in the current condition of the earth. A good bit of people seem to be in agreement that due to the actions of humans, the earth’s climate is increasingly getting worse and that if things don’t change, than everyone living on earth will be facing the consequences. However, this is not entirely true. The fault of climate change does not fall solely on the shoulders of mankind, but on the earth as well.
One of the most compelling and difficult environmental problems society faces today is climate change. People do not realize how much the environment has changed for the worse in the last ten years, until they are told that the last two decades of the 20th century have been the hottest in the last 400 years, according to climate studies (Conserve Energy Future). Today, the carbon dioxide levels have reached 396.81 parts per million (ppm). “Carbon dioxide (CO2) has also increased over the last 100 years-- from about 300 ppm to 370 ppm. Interestingly, the majority of these additions have occurred in the last 50 years, when temperature increases have been the slowest” (geocraft).
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
Global warming is the rise in the temperature on the earth’s surface. The planet’s temperature is rising and we are the cause for this. There are a few ways greenhouse gases are responsible for the warming and humans producing them in a variety of ways. Since the 1970s, 90% of the warming has continued on the earth’s surface and in the ocean’s, as well. Even though the oceans dominant role is energy storage, the term global warming is also referred to the rise of temperature in the air and sea at the earth’s surface. Global warming has been rising and the world is being threaten by the effects. “The risk of catastrophic climate change is getting worse, according to a new study from scientists involved with the United Nations Intergovernmental Panel on Climate Change (IPCC).” (Biello) Threats ranging from the deconstruction of coral reefs and serious weather occurrences like droughts, floods and hurricanes. They are becoming more likely as the temperature change is already under its way. Most people thought that global warming would only affect certain species and only parts of the world but nature has been cooperating with our theories of the effects on global warming and climate changes, unfortunately. There are many causes of global warming as in deforestation, most of the warming comes from the combustion of fossil fuels in vehicles, factories and electricity production. The effects are threatening to our lives, the environment, the wildlife is at risk, etc.
The importance of understanding global warming will control the impact it has on the Earth’s environment. Global warming is the increased warming effect of the atmospheric temperature resulting in a change of the Earth’s climate (USGS.gov, 2008). The increase warming of the temperature is the result from two greenhousegases such as carbon dioxide and methane that are being filtered and trapped into the Earth’s atmosphere. The layers of Earth’s atmosphere is to protect life from high-energy radiation and the frigid vacuum of space (nasa.gov, 2010), but if the atmosphere’s layers becomes thinner, its vital role of protection will diminish. Landfill wastes, industries and deforestation are why global warming exists, in turn will affect all life on Earth.
The amount of CO2 in a planet's atmosphere affects the temperature of the planet. As more and more CO2 builds up in the atmosphere, less heat can escape and the planet gets hotter. The CO2 traps radiation from the sun like a greenhouse. This is called global warming or the greenhouse effect. Global warming is becoming a serious problem and CO2 is the major cause. The earth is now warmer than it has been in 1000's of years. The amount of CO2 deposited in the earth's atmosphere from human activities is expected to double by the year 2050. It could possible increase by four in the future with developing countries, such as China, anxious to improve their standard of living.
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 as 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.
Global warming and the greenhouse effect are issues discussed by scientists all the time. A natural process that keeps earths temperature at a livable rate is called the greenhouse effect. The energy from the sun warms up the earth when the rays from the sun are absorbed by greenhouse gasses. The gasses then become trapped in the atmosphere. Carbon dioxide, water vapor, methane and nitrous oxide are the most common greenhouse gasses. Greenhouse gases cause the radiant heat of the sun to be trapped in the Earths lower atmosphere which causes global warming. If there weren’t any greenhouse gasses, the earth would be really cold due to very little sun rays being absorbed on the earth. Global warming can and will lead to several problems that affect the environment in which we humans live in. These problems can lead to warmer temperatures all around the world, it can endanger animals and the wildlife, and it can lead to widespread flooding from the glaciers melting. Here are a few more future effects that I will discuss in more detail about. Damage to human health, Severe stress on forests, wetlands, and other natural habitats, how fish will be affected. Global warming is a serious problem that will affect our generation when we are older.
Global Warming is a very controversial set words known worldwide. Global Warming is “the recent increase in the world's temperature that is believed to be caused by the increase of certain gases (such as carbon dioxide) in the atmosphere. (Merriam-Webster).” We have all heard the term Climate Change and/or Global Warming, but is it actually happening or is it a hoax?
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.
