Essay on Green House Effect and Global Warming

Green House Effect and Global Warming Essay 1 (100 words)

Greenhouse effect is caused by various green house gases in the atmosphere. All the green house gases available in the atmosphere allow the passage of short wavelengths of visible lights of sun through the transparent medium, absorb heat and check the infrared radiations of longer wavelength to pass back to the space. In this way green house gases trap the heat from long wavelength radiations which result in increased temperature of the earth’s surface. Our earth’s surface is getting warm day by day causing climate change, weather patterns change and declining the healthy living of human beings, plants and animals.

Green House Effect and Global Warming Essay 2 (150 words)

The atmosphere of earth receives energy on daily basis from various resources including sun. However, it is a natural cycle that earth’s atmosphere absorb heat which again passes back to the space in order to maintain the natural cycle in the universe. But, nowadays, increasing level of green house gases in the environment released through many sources has disturbed the natural cycle by trapping heat from many resources and protecting them to go back to the space. So the current environment has become warmer than the earlier environment.

More than 50% of the heat available at the top of the atmosphere gets absorbed by the earth’s surface. The level of excess heat trapping is increasing with the rising concentration of carbon dioxide and other green house gases in the atmosphere. Carbon dioxide gas has strong absorption power and absorbs infrared radiations however does not allow to escape back into space and cause global warming.

Green House Effect and Global Warming Essay 3 (200 words)

Greenhouse effect is a process caused by the green house gases during which thermal radiations of the earth’s surface gets absorbed which again re-radiated to all directions instead of escaping back to the space. Re-radiation of the heat increases temperature in the lower atmosphere of the earth which elevates the average surface temperature. Green house gases make a sheet like blanket in the atmosphere which allows heat to come inside however does not allow them to go outside and increase earth’s temperature. There are many gases come under the category of green house gases but four major gases are named as water vapour, methane, carbon dioxide and ozone.

Some other gases like clouds which are considered as non-gas contributor to the greenhouse effect, but truly they absorb and emit infrared radiations and thus involves in green house effect. There are many reasons of increasing green house gases in the atmosphere however one main reason is human activities such as burning fossil fuels in various ways, clearing of forests, etc causes global warming. Incoming radiations from sun become visible lights having temperature of 6,000 K which gets absorbed by the earth’s surface and disturbs the whole ecological balance.


Green House Effect and Global Warming Essay 4 (250 words)

Greenhouse effect is the process on the earth planet caused by the gases trapping heat and energy from the various sources. Such gases are called as green house gas like CO2, methane, nitrogen oxide, CFCs, ozone, etc trap heat and warm the earth surface. Such gases hold the heat in the earth atmosphere and cause many changes in the climate and weather. Global warming causes increase in heat waves, floods, droughts, increase in sea level, melting glaciers, endangering many animals and plants species, and negatively affected the way of living of human beings.

Some major green house gases are carbon dioxide, water vapour, methane, and ozone are hugely affecting the environment. The main natural sources of increasing CO2 level are decay of animals and respiration. And other main reason of decreased utilization of CO2 is plants cutting. Plants are the main source of utilizing carbon dioxide and maintaining the level of oxygen. Plants also have ability to reduce the emitted greenhouse gases through natural cycle. Use of refrigerator produces chloro fluro carbons which is a green house gas. Major cause of global warming is carbon dioxide pollution because of increasing industrialization and transportation measures.

Green House Effect and Global Warming Essay 5 (300 words)

In the modern age of global warming where everybody is talking about weather and climate change however nobody is thinking about solving it. According to the research, it has been found that average earth temperature has been raised by 0.2 degree celsius in every decade. Temperature and global warming, both are affecting each other. Global warming has become an imminent threat to the existence of life on the earth. Many green house gases absorbs high amount of solar energy and heat on daily basis as well as warming the earth surface. Earlier, most of absorbed heat was radiated back to the space by the earth in order to maintain natural process and balance of heat and energy in the environment however this process has been stopped.

Nowadays, once heat and energy absorbed on the earth by the green house gases do not go back to the space and remains on the earth. The availability of high level of heat on the earth causes many negative effects and disturbs the ecology balance. There are many green house gases available on the earth however carbon dioxide and water vapour have more power to absorb infrared radiations of the earth and block such radiations to go back to the atmosphere. All the absorbed heat gets re-emitted to the earth’s surface and heat up the whole earth’s surface by increasing the temperature is known as green-house effect.

Increasing temperature causes both carbon dioxide and water vapour to get combined which impacts the global climate. This combined effect may increase the temperature by 30 degree Celsius in the surface temperature if the level of CO2 becomes double. The most alarming fact about the ever increasing surface temperature by 1 degree Celsius may hugely affect crop production all over the world due to warming of surface layer.

Global warming and greenhouse effect are the major environmental issues catching the attention of everyone because of the clear climate changes. Greenhouse effect is considered as the natural process however going very fast nowadays and has become very serious because of some human activities. Greenhouse effect caused by the green house gases has to do a lot with the global warming. Green house gases are human released gases through many activities like deforestation, industrialization, use of electricity in every area of work, and so many. There are some natural sources of releasing green house gases however they are in balance. Greenhouse effect is continuously altering the temperature of earth’s surface.

Such a huge alteration in the temperature causes earth to get warmer day by day which results in the global warming. There are many benefits as well as disadvantages of the greenhouse effect to the lives on earth. In the absence of it, earth may get too cold and in the presence of it, earth may get too hot. Both are the harmful to the living beings so, it is required to keep it in balance. There are many causes of the greenhouse effect. Three of them are most common and major cause of greenhouse effect which are CO2, water vapour, and methane. Water vapour is known as natural atmospheric gas however highly strong to absorb sun rays heat. 80 percent of the total natural greenhouse warming is caused by the water vapour and left 20 percent by other gasses.

Carbon dioxide gas is considered as the second biggest heat absorber on the earth which absorbs heat from sun rays. The major reason of CO2 emission is human activities affecting the level of carbon dioxide in the earth’s atmosphere. Deforestation and fossil fuels burning are the main human made reasons for CO2 emission. This continuous in carbon dioxide and other gases causes earth’s temperature to increase and make it warmer than before. Methane is more powerful than CO2 and can absorb 25 times more infrared radiations. This gas is created by the biological activities like digestive process of domestic animals, rice cultivation, leakage in domestic and industrial gas lines, etc. according to the Environmental Media Services Organization, it is found that only through the greenhouse effect the earth’s surface temperature may increase by 6 degrees by the year 2100. Global warming is affecting the whole ecological balance, sea level, corals reefs, marine life, plants, human beings, etc.

Global Warming Essay

1. Global Warming Essay  [100 words]

Why do you think temperature goes too high in summers and too low in winters? Well, such a phenomenon is known as Global Warming.

Global Warming is the extreme rise or increase in the temperature of the surface of the Earth.
Earth’s surface includes both land and water which means that the temperature of not only land increases but that of water as well. Such heat creates many problems for all the living beings like plants, animals and human beings on Earth.

Global Warming is majorly the result of the increased Greenhouse effect. Because of this phenomenon, the water level of both sea and ocean has increased. Such a high increase in the level of water is unwanted and risky too as it can even result in a natural calamity like a flood.

We must take strict actions to prevent such natural disasters and to save our planet Earth.

2. Essay on Global Warming [200 words]

What is Global Warming?

In the most straightforward words –it is the heating up of the Earth’s atmosphere due to non-stop rise in temperature. The primary cause of temperature rise is greenhouse gases.

Global Warming happens because the amount of greenhouse gases like Carbon dioxide, Nitrous Oxide, Methane, etc. has increased mostly in last few years. These gases in the atmosphere soak up or absorb all the heat and raise the temperature which is known as greenhouse effect. This heat creates problems for all the living beings (plants, animals, and humans).

The greenhouse effect is necessary also because it keeps the Earth warm which makes life possible else Earth would freeze. But because of increasing greenhouse effect –Global Warming is taking place.

Global Warming leads to many serious effects which affect the environment severely. Some of the common ones are high sea and ocean level, destruction of aquatic life, high temperature, extreme weather conditions, melting of ice and glaciers, etc.

There are some prevention steps like the planting of trees, forestation, decreasing the use of hazardous chemicals, using of public transport, using wind and solar energy, etc. These measures can reduce the effect of global warming to an extent.

Global Warming is an important topic that can create enormous problems for the existence of life on Earth. Hence, taking measures to reduce Global Warming has become very important.

Model Answer:

Scientists have observed that the earth’s average temperature has risen substantially over the past centuries. Humans can be blamed for this as they have augmented the greenhouse emissions which is the leading cause of increasing temperatures. This essay will analyse the causes of global warming and will suggest remedies to lower the risk associated with this alarming problem.

Modernization, urbanisation, and Industrialization remain the cause of the rise in the overall temperature on the earth’s surface. Industries and vehicles emit a lot of harmful gases which leads to the pollution of air as well as increases the heat. Burning fossil fuels is the primary reason for global warming. Coal and gas are used to generate electricity which results in the emission of carbon dioxide in the air. Deforestationis another reason for this problem.

We can curb global warming by taking small steps like switching off lights and electrical appliances when not in use, using solar energy to heat water, switching to electric cars, growing plants, etc. These are some steps we can take care of at an individual level. The government should also promote the use of renewable energy instead of fossil fuels. In addition to that, monitoring factories, car industries and the cutting of trees will help reduce global warming.

To conclude, although global warming is a serious issue, there are steps that governments and individuals can take to reduce its effects. We must collectively come forward to save our planet.

3. Global Warming Essay: Causes, Effects & Solutions

Introduction

Global warming is a phenomenon due to which the temperature of the earth’s surface; land, water, and atmosphere, is rising year-by-year due to many natural and human-made causes.

Causes of Global Warming

The primary reason for global warming is the increase in the levels of greenhouse gases within the earth’s atmosphere. These gases absorb much of the heat that’s radiated out of the earth’s atmosphere. As the concentrations of these gases in the atmosphere increase, more and more heat energy that otherwise leaves the atmosphere is absorbed. Hence, resulting in an overall increase in the temperature of the earth’s atmosphere, land, and water. The rising levels of greenhouse gases are the primary cause of the phenomenon: Global Warming.

The level of greenhouse gases in the atmosphere is rising due to natural as well as human-made factors. The most prominent contributors to the rise in the level of greenhouse gases would be overpopulation, deforestation, farming, and electricity generation.

Effects Of Global Warming

The impact of global warming is both: short-term and long-term. The long-term effects, however, are much more significant. A reduction in the snow cover surrounding the poles is one significant long-term effect. In fact, as things stand today, the poles are already melting.

Sea-level consequently, is already growing. If things continue to move along this trajectory, it’s predicted that shortly many coast-line countries such as Singapore, Fiji, Egypt, Bangladesh etc. will soon be underwater.

When countries go underwater, there will be widespread damage to flora and fauna that live in these countries. The loss of life will be immeasurable. People who lived in these countries will migrate to other countries. Such migration will cause many economic and political complications in the countries that they choose to relocate. Many people will be fighting for the same land, the same food, the equal job opportunities.

What’s worse is that one of the other long-term effects of global warming is desertification. Desertificationis a type of land degradation in which a relatively dry area of land becomes increasingly arid, typically losing its bodies of water as well as vegetation and wildlife. The impact of widespread desertification is that the land which was earlier available for cultivation is no longer arable. Hence, there will be lesser land to grow food. Smaller area to grow food for more people equals to disaster. It’s a glimpse into the adverse impact that global warming can have in the long-run.

Solutions To Global Warming

Global warming is not a problem with a direct answer. We can not stop this phenomenon entirely, but it can be slowed down. To slow down global warming, every individual on this planet needs to take ownership of this problem that’s been created by them. The crux of the solution lies in reducing the abundance of greenhouse gases released into the atmosphere.

  • Reducing Greenhouse Gas Emissions

Out of all the human activities that contribute towards the release of greenhouse gases into the atmosphere, none is more harmful than the burning of gasoline. E-vehicles which do not use gas and instead run on electricity are gaining traction in the marketplace today. Car companies around the world have taken some initiative towards reducing pollution by manufacturing E-vehicles. Volvo, for example, has come out in public and stated that they would soon stop producing petrol and diesel powered engines in favour of E-vehicles and hybrid vehicles.

Renewable energy is one of the most effective tools we have in the fight against climate change. Generating electricity using these renewable sources will significantly slow-down the global warming process. Generate electricity using renewable sources like wind energy, solar energy, geothermal energy

Adopting the habit of recycling, too, will help slow down the process of global warming. The more we recycle, the lesser we waste. And the lesser we waste, the lesser we pollute the earth.

Conclusion

The human being is a selfish race. If we want to survive, we need to change our selfish ways. If we do not change our selfish means, then it’s highly possible that the children of the present generation may not live a life like the one they are living today. We must come forward to save our planet, Earth.
