Global Warming Essay In English 250 Words To Describe

Global warming is the very hot topic now because of being high risk environmental issue. Students are generally assigned to write or say something about the main causes of the global warming. In order to help your children, we have provided some easy paragraphs and simple long and short essay on the causes on global warming.

Essay on Causes of Global Warming

Causes of Global Warming Essay 1 (100 words)

Global warming is the gradual warming of the earth surface because of the continuous increasing in the temperature of the atmosphere due to some natural and human made causes. The main cause of the global warming is the collection of greenhouse gases in the earth atmosphere which work as a blanket and trap lots of heat causing rise in temperature of the atmosphere. CO2 (also called carbon dioxide) gas is not good for the atmosphere, if it remains longer in the atmosphere, it would trap heat extremely which ultimately increase global temperature. High level of CO2 emissions in the atmosphere are caused by the burning of fossil fuels, cars, vehicles, coal-burning power plants, etc.

Causes of Global Warming Essay 2 (150 words)

Global warming is caused by two reasons, one is natural causes and another is human made causes. Human beings are doing deforestation to a great extent however trees are main source to utilize carbon dioxide and perform global carbon cycle to maintain the percentage of this gas in the atmosphere. Deforestation has almost stopped this positive process of the plants of utilizing the CO2 which in turn increases the level of atmospheric carbon dioxide and rise in atmospheric temperature day by day.

Population growth is another main cause of the global warming. Increasing human population on the earth increases the need of living land and destruction of the forests. Increasing demands of the number of vehicles by the human beings cause fossil fuels to burn more which ultimately increases in the level of atmospheric carbon dioxide. The use of fossil fuels by the human beings in the transport vehicles cause carbon emission which gets collected in the atmosphere, trap heat, increase atmospheric temperature and cause global warming. Sulphur group gas (release from the burning of fossil fuels) is also very harmful which contribute around 30 percent rise in the global warming.

Causes of Global Warming Essay 3 (200 words)

Global warming is the ultimate rise in the atmospheric temperature which is caused by the some natural processes or some man-made causes. The most important cause of the global warming is the cutting of the plants and increasing level of burning of fossil fuels. Other reason of global warming is regular climate change cycles which repeat over a period time. From the creation of the earth the cycle of cooling and cycle of warming continues till now. However, global warming is also increasing by the some man-made causes which need us to worry about and start prevention methods.

Methane greenhouse gas is another cause which is released from the animals like cattle. Wetlands and tundra geography also contributes to release of this gas into the atmosphere which in turn traps heat and causes increase in warming of planet. Solar cycles, sunspots and rotation of the earth are also some natural causes of the global warming. In this, planet warms naturally without human efforts and contributions. Because of the sun spots and solar flares, earth temperature increase does warm up some but this is usually temporary, and when the solar cycle cools off so does the earth. However it is temporary and causes cooling in another cycle. Volcanoes are also a natural cause of increasing global warming.

Global warming is causes by the increase in the temperature of the planet gradually. It is gradual process however very dangerous for the whole human fraternity. It is the indication of the end of the life on this planet if the effects of global warming continue. Natural cause of the global warming is the variations in the solar radiation, solar flares or sunspots, etc are directly impacting the global temperature. Earlier in the seventeenth century the average global temperature was around 1 degree Celsius which was much cooler than today.

Some changes in the sun activity charged particles to originate from the exploding stars of galaxy which enters to the atmosphere and ionize with small moisture particles and form water droplets and then clouds. Such clouds causes reflection of sun energy back to the space and become the reason of rise in global temperature. Natural forest fires also cause increase in the atmospheric temperature as vegetation burning releases stored carbon and increase level of green house gasses. Melting permafrost in the North and South Poles at high level also contributes to the global warming. Other natural causes are the changes in solar activity, volcanic eruptions, natural forest fires, etc.

The main causes of the global warming are the human made causes which are deforestation, increasing human population, increasing demand of the vehicles, burning fossil fuels, burning of coal, oil, gas, etc which increases the atmospheric greenhouse effect and ultimately enhance the temperature of the atmosphere.

Causes of Global Warming Essay 5 (300 words)

The main cause of the increasing global warming is human being however some natural causes also contribute to the global warming. The main culprit of global warming is the increase in greenhouse gases in the atmosphere of this planet. Burning fossil fuels and deforestation causes carbon dioxide to store in the atmosphere which traps heat and becomes the reason of earth warming and greenhouse effect causing global warming. The most important contributors of causing greenhouse effect are carbon dioxide gas, water vapour, methane and ozone.

Coal and oil mining releases the methane gas to the atmosphere. Other natural leakage causes additional source of methane release. Human being are cutting down trees and forests to a great level per year which affect the natural carbon cycle and cause carbon dioxide gas to store in the atmosphere. Plants are considered as the main source to utilise all the carbon dioxide gas on the earth. In this way the increasing concentration of carbon dioxide gas causes increase in the greenhouse effect which again warm the atmosphere by increasing temperature.

Release of nitrous oxide from the fertilizers (used for crops) and gases used in the refrigerator including other industrial processes are also the main factors of global warming. Melting ice releases methane as ice has trapped a compound called methane clathrate which released after melting. Also the ice caps and glaciers reflect sunlight back to the space (means preventing earth from high temperature sun rays) and after melting of ice this process stops and causes earth to warm. Burning of wood at high level releases the oxidizable carbon in the earth atmosphere which ultimately elevates earth temperature. An emission of chlorofluorocarbons (used in the freeze) is the major reason of abnormal earth warming. It does not trap heat however it releases chlorine in the presence of UV sun rays which goes to the atmosphere and weakens the ozone layer by changing ozone molecules into the oxygen molecules.

Global warming is a gradual process however increasing day by day because of the human beings. There are many natural causes also but they are contributing less than the human made causes. Now the effects of global warming can be easily felt by us such as decreasing winter season length and increasing summer season length. Earth is getting warm and warmer, even in the last decades the temperature of the earth has increased to a great extent. There are some effective measures following on the global level by the human beings may reduce the effect of global warming. Increasing effect of global warming indicates the end of life existence on the earth. The main reason of the origin of this demon is the human mistakes.

Burning fossil fuel naturally or by man increases the level of carbon dioxide emissions (coal powered plants-93%, power production industries-40%, and other industries) in the atmosphere. Other reason of increasing CO2 emissions is increasing demand of the vehicles on the road. Vehicles use gasoline which causes emission of CO2 gas as a by-product. Some faulty engines of the vehicles or vehicles giving less mileage contribute more carbon emission. Now-a-days, automobile manufacturers have been warned to manufacture more efficient engines of the vehicles in order to reduce carbon dioxide gas emission to the atmosphere. Increasing demands of the vehicles are creating more challenges to the global warming.

Deforestation and increasing human population are the main reasons of the increasing global warming. Deforestation causes removal of plants from the earth which disturbs the natural carbon cycle. Plants are the main utilizers of the carbon dioxide gas as their food and when the number of plants decreases on the earth cause increase in the level of this harmful gas in the earth atmosphere. The released CO2 gets collected in the environment and absorbs more heat from the sun rays and ultimately increases the temperature of the earth. The increased earth temperature cause increase in the global warming.

Animals are also the source of releasing some methane into the atmosphere which is also harmful for the earth. Burning of coal, oil, and gas causes increase in atmospheric greenhouse effect and rise in temperature which causes ice caps to melt and heat the earth. Ice caps play great role in the cooling of the earth by reflecting sun heat back to the space, however cooling effects lasts when ice caps melts.

Essay on Global Warming

Global Warming Essay 1 (100 words)

Global warming is a major atmospheric issue all over the world. Our earth’s surface becoming hot day by day by trapping the sun’s heat and rise in the level of atmospheric carbon dioxide. The bad effects of it increasing day by day and causing major problems to the living of human being. It has become one of the subjects of big social issues which need social awareness to a great level. People should know its meaning, causes, effects and solutions to solve it immediately. People should come forth together and try to solve it in order to save life on the earth.

Global Warming Essay 2 (150 words)

Global warming is a big issue of the atmosphere on the earth which cause continuous rise in the surface temperature of the Earth. It has been estimated that in next 50 or 100 year the temperature of earth would be increased to a great level which would create big problem of living on earth. The highly known and most basic cause of increasing the Earth’s temperature is continuous rise in the atmospheric carbon dioxide.

Rise in the carbon dioxide level is the use fossil fuels like coal and oil, deforestation (cut down of plants) by the human beings on Earth. Decreasing number of the plants on the earth increases the level of carbon dioxide, as plants are the main source of the using carbon dioxide released by the human being (as a by-product of respiration) and other means. Increasing level of Earth’s temperature creates lots of problems like sea level becomes hotter and higher, glaciers melt, flood, strong storms, lack of food, diseases, death, etc.

Global Warming Essay 3 (200 words)

Global warming is the steady and continuous rise in the level of earth temperature. Out earth surface is becoming hotter day by day just because of some unnoticeable habits of human beings all across the world. Global warming has become the most worrying threat for the earth’s atmosphere as it is reducing the life possibilities on the earth day by day through a continuous and steady declining process.

Before planning the solutions of the global warming, we must think about the causes and effects of it on the atmosphere in order to get sure that we are in right direction of getting full relief from this issue. The continuous warming of the earth surface is the increasing emission of CO2 in the environment. However, the increasing level of CO2 is caused due to many reasons like deforestation, use of coal, oil, gas, burning of fossil fuels, burning of gasoline for transportation, unnecessary use of electricity, etc which in turn causes rise in earth temperature. Again it becomes the reason of rising sea level, occurrence of flooding, storms, cyclone, ozone layer damage, changing weather patterns, fear of epidemic diseases, lack of food, death, etc. We cannot blame any single entity for this as each and every human being is responsible for the increasing threat of global warming which can be solved only by the global awareness and kind efforts of everyone.


Global Warming Essay 4 (250 words)

Global warming is a steady process of continuous rise in the level of Earth temperature. Global warming has become one of the biggest problems faced by the world now. It is believed that increasing level of carbon dioxide gas and other greenhouse gases on the earth are the main reasons of heating the atmosphere of earth. If it is not noticed and solved immediately by the efforts of all countries worldwide, it would boom its effects and cause end of life on the earth a day.

Its threatening effects are increasing day by day and creating danger for human life. Global warming is the main and only reason of rising sea level, flooding, changes in weather patterns, storms, cyclone, epidemic diseases, lack of food, death, etc. The only solution to solve the issue of global warming is the individual level social awareness. People must be aware of its meaning, cause, bad effects and other things about global warming to get it eradicated from worldwide and make the possibilities of life on earth forever as usual.

People should stop producing C02 by just stopping their bad habits such as stop the use of oil, coal and gas, inhibit cutting plants (as they are main source to absorb carbon dioxide and produce oxygen), minimize the use of electricity, etc. Just small changes in everyone’s life all over the world, we can be able to stop the huge negative changes in the atmosphere by lessening the effects of global warming and even stop it a day.

Global Warming Essay 5 (300 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. As gradual increase in the earth temperature calls various threats as well as makes the existence of life hard on this planet. It enhances the gradual and permanent changes in the earth’s climate and thus affecting the nature’s balance.

Rise in the CO2 level on the earth impacts the human life to a great level through continued heat waves, sudden occurrence of strong storms, unpredictable and unexpected cyclone, damage to ozone layer, floods, heavy rain, drought, lack of food, diseases, death etc. It has been researched that increasing emissions of CO2 in the atmosphere is because of the nonstop burning of fossil fuels, usage of fertilizers, cutting forests, extra use of electricity, gases used in refrigerator etc. According to the statistics, it has been noted that by 2020 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 Essay 6 (400 words)

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. It has impacted the nature’s balance, biodiversity and climatic conditions of the earth over decades.

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 20th 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 1983, 1987, 1988, 1989 and 1991 as the warmest six years of the past century. This increasing global warming calls the unexpected disasters on the earth like flood, cyclones, tsunami, drought, landslides, ice melting, lack of food, epidemic diseases, death etc thus causing imbalance to the nature’s phenomenon and indicating end of life existence on this planet.

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.

What is Global Warming

Global warming is a gradual process of heating of earth’s surface and whole environment including oceans, ice caps, etc. The global rise in atmospheric temperature has been clearly noticed in the recent years. According to the Environmental Protection Agency, in the past century there is increase in the earth’s surface average temperature by around 1.4 degree Fahrenheit (means 0.8 degrees Celsius). It has also been estimated that global temperature may increase by another 2 to 11.5 degrees F in the next century.

Causes of Global Warming

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 20th 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 10-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 2000. There is no any clear trend of ozone layer declination in the winter or summer seasons.

Presence of various aerosols in the atmosphere is also causing earth’s surface temperature to increase. 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.

Effects of Global Warming

The effects of global warming have been very clear in the recent years because of increasing sources of global warming. According to the U.S. Geological Survey, it has been recorded that there were 150 glaciers located in the Montana’s Glacier National Park however because of increasing effect of global warming, only 25 glaciers are left. 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 2012 has been recorded as hottest year since 1895 and year 2013 together with 2003 as the warmest year since 1880.

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.

Solutions of Global Warming

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). However, we should not get back and try everyone’s best to reduce the effects of global warming by reducing the human causes of global warming. 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.
