In accordance with the Intergovernmental Panel on Climate Change, climate change is defined as a “change in the state of the climate that can be identified (e. g. using statistical tests) by changes in the mean and/or the variability of its properties, and that persists for an extended period, typically decades or longer” (30). Earth’s atmosphere is comprised of different gases, some of which, such as water vapor and carbon dioxide (CO2), take part in the so-called natural greenhouse effect. Because of their activities, humans have altered the natural process causing the increase of these gases in the atmosphere that, as a result, leads to climate change and the rise of the planet’s average temperature, in particular, i. e. global warming.

The first anthropogenic cause of climate change is proved to be the increase of greenhouse gases in the atmosphere. Scientists started studying climate and atmospheric composition in the nineteenth century, and this examination is taking place these days. The evidence from observations of the surface and atmosphere shows that the amount of greenhouse gases has increased dramatically. Among all the gases in the atmosphere, it is carbon dioxide that appears to be the most important of greenhouse gases.
Compared to the data from the eighteenth century, today the atmospheric abundance of carbon dioxide is 40% greater (Hartmann, Tank, and Ristucucci 161). Natural amounts of CO2 varied from 180 to 300 ppm (parts per million), these days the amount of carbon dioxide is about 400 ppm (Environmental Defense Fund). In fact, the same state of things is with the number of other gases. ...Download file to see next pagesRead More

Ozone depletion causes global warming

...? Ozone Depletion Causes Global Warming Ozone layer is the “blanket” that is considered essential for the survivalof all living things on earth. Its depletion results to global warming. Global warming later on leads to climate change. Having an increase in temperature around the world give stresses to the nature and later on affect the well-being of living things. Survival is at stake once the existing problems were not to be dealt with seriously. Thorough understanding is needed before necessary actions can be done. In line with that, it would help in the discussion if the ozone layer and global warming are both defined. Ozone is made up of three atoms of oxygen which is poisonous when people inhale it especially at high concentration...

Ozone Depletion Causes Global Warming

...? Ozone Depletion Causes Global Warming Ozone layer is very much important for all living things because its depletion leads to global warming. Having an increase in temperature around the world give stresses to the nature and later on affect the well-being of living things. Before going deeply into ozone depletion, it would help in the discussion if the ozone layer and global warming are both defined. Ozone is an oxygen variation with three atoms unlike the air human beings breathe which is composed of two atoms of oxygen. The form makes ozone very reactive and may cause poisoning at high concentrations. When it is formed near the surface of the earth, it is toxic and may cause asthma while it is a blanket of protection from solar...

The causes and effects of Global warming

Statistics indicate that in the last 100 years, the temperatures have risen by approximately 0.8 o C and it is projected that this will continue to worsen as it is expected that the rise could reach 1.7o C in the next few years if stern measures are not taken to avert this catastrophe (Christian 28). Global warming mainly results from over concentration of carbon dioxide (co2) and other harmful gases, such as methane and nitrous oxide, in the atmosphere (Michaels 40). This is due to the fact that these gases have the capability to trap heat from the sun and storing it to the extent that temperatures in the surroundings remain extraordinarily higher than normal. In order to understand this, one may use the example of a car, which,...

Global warming: What it is, its Causes and Effects

... gets transmitted back to outer space (Houghton, 2004). Some other causes of global warming is that there is a misinformation campaign, wherein most of the people involved are either not fully aware of the whole situation, or are just following the tide created by the media and politicians (Leroux, 2005). Global warming as a result of various factors can be summarized in the following diagram: Fig. 1 Fishbone diagram of global warming and its causes The main problem is that global warming has escalated to greater heights due to the accumulation of CO2 levels at a rapid rate. From the industrial revolution up to the present, the increase in the use of fossil fuels to power up everything, from houses to automobiles as well as the increase...

Debate on the causes of global warming

...Tom Hilberg Rhetoric and the Public Sphere 22 April 2007 Global Warming: Debate and Deliberation and the Public Sphere Global warming is one of the most important world issues in the late twentieth century and the early twenty-first century. The effects of global warming could be very destructive to worldwide civilization. Debate on the causes of Global Warming, the extent of Global Warming, and even the existence of Global Warming is very common in the public sphere. There is also debate over which methods should be used to stop the process. Although Global warming is debated heavily throughout all forms of media, the quality of the rhetoric used by both sides in the debate is mostly very poor, especially in the more mainstream media...

Global warming, its scope and causes

...IMPACT OF GLOBAL WARMING ON HUMAN HEALTH Global warming, its scope and causes Global warming refers to the increase in the overall temperature of the atmosphere, ocean bodies and the landmasses of our planet. Global warming followed by cooling is a geological phenomenon. During the past 4.5 billion years, planet earth has warmed and cooled many times. Presently, it is undergoing a very rapid warming, which is the outcome of human activities like rampant and indiscriminate deforestation and reckless exploitation of natural resources for industrialization. One of the main causes of this rapid warming has been attributed to burning of industrial fuels like coal, oil and natural gas. Upon combustion, fossil fuels like coal and petroleum...
