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.
However, gradually declining ozone layer is the big indication of increasing global warming of the earth surface.
Harmful ultraviolet sun rays are entering to the biosphere and get absorbed by the green houses gases which ultimately increase the global warming. According to the statistics, it has been estimated that the size of ozone hole has been twice the size of Antarctica more than 25 million km2 by There is no any clear trend of ozone layer declination in the winter or summer seasons.
Atmospheric aerosols are fully capable to scatter causes cooling to the planet and absorb makes air warm the solar and infrared radiations. They are also capable to change the microphysical and chemical properties of the clouds and possibly their lifetime and extent. The increasing amount of aerosols in the atmosphere is because of human contribution.
Dust is produced by agriculture, organic droplets and soot particles are produced by biomass burning, and aerosols are produced by the industrial processes through the burning of wide variety of products in the manufacturing process.
Various emissions by means of transport generate different pollutants which get converted to the aerosols through many chemical reactions in the atmosphere. The effects of global warming have been very clear in the recent years because of increasing sources of global warming. According to the U. Huge level climate changes are making hurricanes more dangerous and powerful. Natural storms are getting so strong by taking energy from temperature difference of cold upper atmosphere and warm Tropical Ocean.
Year has been recorded as hottest year since and year together with as the warmest year since Global warming causes lot of climate changes in the atmosphere such as increasing summer season, decreasing winter season, increasing temperature, changes in air circulation patterns, jet stream, rain without season, melting ice caps, declining ozone layer, occurrence of heavy storms, cyclones, flood, drought, and so many effects.
Many awareness programmes and programmes to reduce global warming have been run and implemented by the government agencies, business leaders, private sectors, NGOs, etc. Some of the damages through global warming cannot be returned by the solution like melting of ice caps. We should try to reduce the emissions of greenhouse gases to the atmosphere and adopt some climate changes which are already happening for years.
Instead of using electrical energy we should try using clean energy or energy produced by solar system, wind and geothermal. Reducing the level of coal and oil burning, use of transportation means, use of electrical devices, etc may reduce the global warming to a great level. Causes of Global Warming Essay. Effects of Global Warming Essay.
Causes and Effects of Global Warming Essay. Prevention of Global Warming Essay. If Global warming continues the world would be in danger. The major effects and impacts of Global Warming are:. 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. There is uncertainty regarding regional forecasts of future precipitation as warming of globe makes it difficult to predict. Also, pattern of agricultural changes, or effects on ecosystems in general are fairly unpredictable.
This also puts threat on the rich biodiversity of the ecosystem.
