Discuss the evidence that Global Warming is happening and is caused by human activity.

Human activities have changed the Earth’s structure after they have existed on it. The beautiful atmosphere of the earth is losing its beauty due the human development activities. Global warming is alarming concern worldwide today. Global warming and its causes is one of the most debated issues today. Global warming refers to the increase of average world temperatures which cause changes in climate. Rising global temperatures have resulted changes in weather and climate. The human activities such as burning of fossil fuel and deforestation, rise global temperature, decline Arctic sea ice and ocean acidification clearly notes that global warming is happening and is caused by human activities.

The burning fossil fuels produce greater amount of carbon dioxide more than amount needed in the atmosphere affecting the natural carbon cycle, although the green house gases are naturally occurring cycle phenomena. Green house gases such as carbon dioxide, methane and nitrous are natural gases. The burning fossil fuels will change carbon into carbon dioxide. Human activities burning fossil fuels such as coal, oil and natural gases are main basic rise in global temperature. These gases are produced by industries and machine that human uses for the development activities. The earth’s atmosphere consists of blanket of gases. These gases function to filter the harmful rays of the sun and to radiate the excess amount of heat produced by the sun rays. This natural phenomenon of filtering harmful rays and radiating excessive heat happens in a normal atmospheric condition. However, the earth’s atmosphere is polluted with poisonous gases like carbondioxide, sul...

  • Importance Of Climate Change Essay

    1379 Words  | 3 Pages

    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

    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.

  • Global Warming: A Look at Both Sides of the Issue

    2372 Words  | 5 Pages

    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

    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).

  • Why Is Climate Change?

    1400 Words  | 3 Pages

    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

    The article “an introduction to climate change” describes in detail about the causes of climate change, and its potential effect on earth. According to this article, the global warming is due to the accumulation of carbon dioxide and other pollutants formed from burning fossil fuels that accumulate on earth’s atmosphere so that light rays are reflected back to the earth surface causing the atmospheric air to heat up. In addition, the article also gives some relevant solutions to global warming such as reducing air pollution and use of “clean energy.”

    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.

  • Global Warming Is A Global Issue

    1043 Words  | 3 Pages

    Many climate scientists, researchers, and environmentalists are expressing concerns about shifts in the overall climate of the earth. It is believed that a dramatically dangerous warming is taking place in the overall global climate, a problem that is referred to as "global warming”. Global warming is the observed century-scale rise in the average temperature of Earth’s climate system. This temperature rise is due to the damaging effects of deforestation and the burning of fossil fuels. It is our responsibility to preserve our planet and our way of living but in order to do that we need to act now. If we continue to destroy the planet with no regard as to how serious this matter is there could be several negative effects to us as human being and other living thing on Earth. This is why global warming is truly a global issue and needs to be tackled collectively. We must to act now in order to reduce the dangerous levels of carbon dioxide emissions and we must to work together.

  • Global Warming: A Global Crisis

    1668 Words  | 4 Pages

    Our planet has managed to survive and thrive for about 4.54 billion years. In the last 2 million years we have caused enough damage and destruction to make our world “broken” beyond repair. We will not be able to get back the world we once had. The reason behind this is global warming, specifically, the increase of the global temperature due to the burning of fossil fuels and the release of greenhouse gas emissions into our atmosphere. If we do not make the issue of global warming a priority in today`s society, our entire way of life will be at risk. There are many reasons why so many people believe global warming should be a concern. Thoroughly examined points include: scientific predictions, rising temperatures, human causes, drastic climate changes and animal adaptations. Though there are several points arguing how global warming should not be a concern, the reality of the matter is that it needs to be taken into consideration on a global scale before it is too late, as to do nothing would have devastating implications on humankind.

    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).
