According to the statistics, it has been noted that by global warming may boom its bad effects if it is not taken under control as CO2 emissions are increasing continuously. The increasing level of CO2 causes greenhouse effect on the earth in which all the greenhouse gases water vapour, CO2, methane, ozone absorbs thermal radiation, which in turn re-radiated to all directions and come back to earth surface causing increase in the temperature of earth surface and lead to global warming.
In order to stop the life threatening effects of the global warming, we should take a permanent break from all the bad habits causing increase in the CO2 level and other green house gases leading to the green house effect and then earth surface warming. We should stop deforestation, lessen the use of electricity, stop the burning of wood, etc. Global warming is the big environmental issue we are facing today as a greatest challenge which we need to get it solved permanently.
In fact, global warming is the continuous and steady process of increasing in the temperature of earth surface. It needs to be discussed widely by all countries worldwide to stop the effects of it. Green house gases like CO2, methane are the main reasons of increasing the global warming on the earth which directly impacts the rising sea levels, melting ice caps, glaciers, unexpected changing climate which represents life threats on the earth.
According to the statistic, it has been estimated that earth temperature has increased to a great level since mid 20 th century due to the increased atmospheric greenhouse gas concentrations globally because of the increased demand of the human living standard. It has been measured that year like , , , and as the warmest six years of the past century. Increasing global warming lead to the more water evaporation from earth into the atmosphere, which in turn become a greenhouse gas and again causes rise in the global warming.
Other processes like burning of fossil fuels, use of fertilizers, rise in other gases like CFCs, tropospheric ozone and nitrous oxide are also the reasons of global warming. The ultimate causes of such reasons are the technological advancement, population explosion, increasing demand of industrial expansion, deforestation, priority towards urbanization, etc. We are disturbing the natural processes through the deforestation and use of technological advancement like global carbon cycle, making hole in ozone layer, etc and allowing the UV rays to come on earth thus increasing global warming.
Plants are the ultimate source of removing extra carbon dioxide from the air and making it in balance thus by just stopping the deforestation and enhancing people for more plantation we can get success of reducing the global warming to a great level.
Controlling the population growth is also a great hand towards reducing the global warming all through the world as it lessens the use of destructive technologies on the earth. The global rise in atmospheric temperature has been clearly noticed in the recent years.
It has also been estimated that global temperature may increase by another 2 to There are many causes of the global warming, some are natural causes and some are human made causes. The most important cause of global warming is greenhouse gases which are generated by some natural processes as well as human activities. The increase in the level of green house gases has been seen in the 20 th century because of the increasing population, economy and use of energy.
Increasing demand of industrialization in the modern world to fulfill almost each need is causing the release of variety of green house gases through many industrial processes in the atmosphere. The release of carbon dioxide CO2 and sulphur dioxide SO2 gas has been increased in the recent years by fold.
The release of carbon dioxide gas varies according to the natural and industrial processes including photosynthesis and oxidation cycles. Methane is another green house gas release in the atmosphere by the anaerobic decomposition of organic materials. Other greenhouse gases are like oxides of nitrogen nitrous oxide , halocarbons, chlorofluorocarbons CFCs , chlorine and bromine compounds, etc. Such green house gases get collected to the atmosphere and disturb the radiative balance of atmosphere.
They have capability to absorb heat radiations and cause warming of the earth surface. Another cause of global warming is ozone depletion means declination of ozone layer over Antarctica. Ozone layer is declining day by day by increasing release of chlorofluorocarbon gas. It is a human generated cause of global warming. Chlorofluorocarbon gas is used at many places as aerosol propellants in the industrial cleaning fluids and in the refrigerators, the gradual release of which causes declination to the ozone layer in the atmosphere.
Ozone layer causes protection to the earth surface by inhibiting the harmful sun rays to coming to the earth. As a consequence of massive loss of forests, global CO, levels rise approximately 0. As we know the forests are the great absorbers of CO,,. There is a close relation between global warming and population growth. Today the large population on earth is using the technologies which are destructive for the earth.
A large portion of carbon emission is attributed to the burning of gasoline in internal-combustion engine of vehicles. Vehicles with poor gas mileage contribute the most to global warming. Besides, the sulphur group gas is the most harmful for this.
Its contribution is 30 per cent in global warming. This gas is also emitted from the burning of fossil fuels. Increase in global temperatures will cause rise in sea level. It will lead to melting of glaciers, changes in rainfall patterns, increased intensity and frequency of extreme weather. As per the latest survey report the rate of melting of glaciers has seen sharp increase in recent times. Even those glaciers are affected from global warming which have been considered permanent.
The shrinking of glaciers is going to pose a major problem of drinking water. The sea levels as a result of melting of glaciers have risen from 0. Scientists have warned in their reports that most of the glaciers will disappear within a period of 15 to 25 years. It will create problems of drinking water and food grains in most of the North American countries. India is not unaffected from it. The Himalayan glaciers have shrunk about 30 per cent after The rise in sea levels is a major cause of concern.
A large number of cities located in coastal areas will submerge in the sea. The damage of rising sea levels is diverse. Buildings and roads close to the water could be flooded and they could suffer damage from hurricanes and tropical storms. Experts believe that global warming could increase the intensity of hurricanes by over 50 per cent. In addition, as the sea rises, beach erosion takes place, particularly on steep banks.
Global warming is causing climate change. There is also prediction of regional climate changes along the ecosystem. One major consequence of global warming arising out of greenhouse effect is the rise in sea level. Four major changes take place prior to this. Thus, the coastal cities and ports may be submerged under sea-water. Many islands may vanish from the earth surface as well as from the world map.
Although changes in sea-level have received much publicity, problems of water availability are likely to be more serious and perhaps more expensive to solve. In future, warmer world will face water crisis in some parts while in other regions it will be wetter than it is now.
Keywords: global warming essay, causes of global warming, global warming solution. Introduction. What is global warming? Global warming is the average temperature of Earth has increases since until now the temperature continuing increasing. Global warming can also refers to climate change that causes an increase in the average of temperature.
Global warming is the increase in the surface and atmospheric temperature generally caused by presence of excess amount of greenhouse gases (such as carbon-di-oxide (CO2), Chlorofluorocarbons (CFCs), etc.) and other pollutants resulting in a change in climate, greenhouse effect, and other negative consequences on the environment.
atmosphere and thus might act as agents to offset global warming, but they also make the air hard to breathe. Because carbon cycle, read Rachel Oxburgh’s essay, isotope levels measured from ice cores and global ice. Global Warming is not controlled, no men, animals will be able to live, grow and thrive. So, we should try maintain the ecological balance to decrease the effects of Global Warming Global warming is the warming near the earth's surface that results when the earth's atmosphere traps the sun's heat. The earth is getting warmer.
Global Warming Essay 5 ( words) Global warming is the continuous rise in warming of the earth’s surface due to the increased level of carbon dioxide gas in the environment. Global warming has become a big issue which need to be solved by the positive initiation of countries all over the world. Global warming is a very hot topic of today’s world and students are assigned to write on global warming essay topics. The teachers ask the students to write papers on global warming, global warming argumentative essay or global warming persuasive essay. A global warming essay is somehow equivalent to any other general essay.
