Global warming refers to the rise in the average surface temperature of the earth. Global warming is caused mainly due to human-induced factors. The main cause of global warming is the uncontrolled emission of greenhouse gases due to activities like industrialization and the burning of fossil fuel. Greenhouse gases, cause an effect known as the greenhouse effect, and trap the Sun’s heat from escaping back into the atmosphere, consequently resulting in a raised surface temperature of the earth. Though, the rise in the earth’s temperature is within 1 degree C, it still causing noticeable effects on the environment.
Long and Short Essay on Global Warming
Essay 1 (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 the level of carbon dioxide gas and other greenhouse gases on the earth are the main reasons for heating the atmosphere of the earth. If it is not noticed and solved immediately by the efforts of all countries worldwide, it would boom its effects and cause the 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 for rising sea levels, flooding, changes in weather patterns, storms, cyclones, epidemic diseases, lack of food, death, etc. The only solution to solve the issue of global warming is the individual level of 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 the 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 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 that needs to be solved by the positive initiation of countries all over the world. As a gradual increase in the earth’s 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.
The rise in the CO2 level on the earth impacts human life to a great level through continued heat waves, a sudden occurrence of strong storms, unpredictable and unexpected cyclones, damage to the 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 vapor, CO2, methane, ozone) absorbs thermal radiation, which in turn re-radiated to all directions and come back to earth surface causing an increase in the temperature of earth surface and lead to global warming.
In order to stop the life-threatening effects of global warming, we should take a permanent break from all the bad habits causing an increase in the CO2 level and other greenhouse gases leading to the greenhouse effect and then earth’s 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 the greatest challenge which we need to get solved permanently. In fact, global warming is the continuous and steady process of increasing the temperature of the earth’s 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 the decades.
Greenhouse gases like CO2, methane are the main reasons for increasing global warming on the earth which directly impacts the rising sea levels, melting ice caps, glaciers, an 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 floods, cyclones, tsunami, drought, landslides, ice melting, lack of food, epidemic diseases, death, etc thus causing imbalance to nature’s phenomenon and indicating the end of life existence on this planet.
Increasing global warming leads to more water evaporation from earth into the atmosphere, which in turn becomes a greenhouse gas and again causes a rise in 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 for global warming. The ultimate causes of such reasons are technological advancement, population explosion, increasing demand for industrial expansion, deforestation, priority towards urbanization, etc.
We are disturbing the natural processes through the deforestation and use of technological advancements like global carbon cycle, making a hole in the 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 deforestation and enhancing people for more plantation we can get success of reducing global warming to a great level. Controlling population growth is also a great hand towards reducing global warming all through the world as it lessens the use of destructive technologies on the earth.

There are many causes of 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 greenhouse gases has been seen in the 20th century because of the increasing population, economy, and use of energy. Increasing demand for industrialization in the modern world to fulfill almost every need is causing the release of a variety of greenhouse gases through many industrial processes in the atmosphere.
The release of carbon dioxide (CO2) and sulfur dioxide (SO2) gas has been increased in 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 greenhouse 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 greenhouse gases get collected to the atmosphere and disturb the radiative balance of the atmosphere. They have the capability to absorb heat radiations and cause warming of the earth’s surface.
Effects of Global Warming
The effects of global warming have been very clear in 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 Montana’s Glacier National Park however because of the 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 the cold upper atmosphere and warm Tropical Ocean). The year 2012 has been recorded as the hottest year since 1895 and the year 2013 together with 2003 as the warmest year since 1880.
Global warming causes a 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, the occurrence of heavy storms, cyclones, flood, drought, and so many effects.
Solutions of Global Warming
Many awareness programs to reduce global warming have been run and implemented by government agencies, business leaders, private sectors, NGOs, etc. Some of the damages through global warming cannot be returned by the solution (like the 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 the solar system, wind and geothermal. Reducing the level of coal and oil burning, use of transportation means, use of electrical devices, etc may reduce global warming to a great level.
