The world have existed since millions of years and through the centuries many changes have occurred from the extinction of the dinosaurs to the evolution of mankind and the development of technology to make life easier, But all thischanges have left scars in the earth and therefore generated problems but in the present day humankind is facing a natural and man-made problem that day by day is becoming more difficult to find a solution, this problem is what scientist called the global warming.
This is a new problem that has been manifesting since a few decades ago since the industrial revolution began and in this moment it isone of the major concerns of most of the developed countries in health, energy and economic issues. The purpose of this work is to inform about what is the global warming and the impacts of this natural phenomenon in the economy and make conscience that is a serious problem, its real and most of all its happening right know.
The global Warming is an increase of the averagetemperature of the earth´s atmosphere and the oceans. The theory of the global warming postulates that the temperature has risen from the end of century XIX due to the human activity, mostly by the Carbon Dioxide emissions that increased the greenhouse effect (Usep, 2008). The Global Warming theory estimates in addition, that the temperatures will continue rising in the future if the emissions of carbondioxide increase. Therefore the future actions to prevent the greenhouse effect will be not sufficient to prevent a time bomb in the major areas of life.
The definition of global warming comes from the middle of last century after 1960 when it was obvious that the levels of carbon dioxide gas (CO2) was seen to be rising rapidly, thus the global temperature climbed between 3 and 5 degreesCelsius before the end of the XXI century. Increasing global temperature will cause sea level to rise, other effects of global warming include changes in agricultural yields species extinctions and increases in the ranges of diseases. The biggest and clearest problem scientist noted was that rising temperatures would surely melt glaciers, raising the sea level and flooding coastal areas (Ippc, 2007,Pg.5)
This is a consequence of the lack of volcanic activity and because of the phenomenon called greenhouse effect but most of all because of the human industry. This anomalies in the earth are causing the raise of both day and night temperatures, In addition the land and sea temperatures are also raising therefore by the end of this century the earth´s temperature will raise around 6 degrees thatis why from 1985 through today the scientist have measured the hottest temperatures ever seen (Ippc, 2007,pg 10).
The greenhouse effect is a natural cycle that begins with the construction of a building to conserve the reproduction of plants, this building keeps the temperature that the plants need in order of a healthy growth. This Buildings are called plant conservatories the shape of thisstructures is a house with crystals in the ceiling that catch the light and the solar radiation therefore the entrance of heat is stable even if in the outside the temperature is colder. This same process occurs in the atmosphere were certain gases catch the heat from the sun and maintain the earth´s crust warm. Without this process the temperatures could be around -20°C. This Effect is essential forlife as long as it remains stable. During the past 150 years this process has suffer of an anomaly which consist in the reflection of the infrared rays that reflect back to the planet by gases like the carbon dioxide, the methane, the nitrous oxide and the ozone (Ippc,2007,Pg.17).
These gases are known as the “green house concentrations” the big amounts of these gases cause that the heat can’t...
