Essay on Role of Human Activities in Global Warming – Short Essay for Kids and Children (Essay 1 – 200 Words)

Introduction:

Role of human activities in Global warming is on the highest scale. We are the major contributors in making the planet hotter and an unlivable place to be. Last century alone has seen unprecedented warming of the earth’s surface thus leading to adverse effects.

Human activities contribute to Global Warming – True?

Human activities are the major contributors to Global Warming and this is an undeniable truth. This is because the atmospheric concentration of CO2 has increased approximately 280 parts per million (ppm) since the pre-industrial era (AD 1000 – 1750) to today’s 400 ppm. Credit goes to the mankind for the increased use of fossil fuels.

Climate Drivers:

Human activities such as emissions from cars and other power plants traps the heat, this phenomenon called forcing makes the planet hotter. Burning fossil fuels also emits tiny particles along with CO2 and creates black soot, this soot has the capability to hold heat and causes heating effect.

Conclusion:

Human activities has induced global warming and so finding a solution to this is their responsibility. Energy efficient technologies should be adopted by everyone. Humans should go back to their basics and start looking at saving the planet from the imminent danger and look for sustainable ways of living. Every human should take it on himself to make the planet a better place to live.


Essay on Role of Human Activities in Global Warming – 10+ Lines Written in English (Essay 2 – 250 Words)

Global warming is caused by different human activities like burning of fossil fuels and farming. These human activities lead to a change in climate by causing changes in Earth’s atmosphere by increasing the amount of greenhouse gases, aerosols and cloudiness.

Burning fossil fuel – When fossil fuels are burned, carbon dioxide is released into the atmosphere. Vehicles, industries and electricity generation is one of the main causes of pollution with carbon dioxide as a source. It can be lowered by using alternative sources of energy like solar, wind. These sources emit less amount of carbon.

Deforestation – Humans are involved in deforestation for urban development or infrastructure development. They cut trees for raw materials like wood and oil. Trees act as carbon sinks and help in maintaining the levels of CO2 in atmosphere. When they are chopped or burnt, all the stored carbon is released back into atmosphere. The effect of deforestation can be reduced by preventing it from happening and through reforestation.

Farming – Animals like livestock produce methane which is a greenhouse gas. It is also another source of global warming.

All these human activities have an overall effect on the climate. The impact of these activities is even greater than any impact caused by natural process like solar changes and volcanic eruptions. These human activities will make the Earth warmer. This in turn will lead to more evaporation and precipitation overall. There will also be warming of oceans and melting of ice caps and glaciers, resulting in rise of sea level.


Essay on Role of Human Activities in Global Warming (Essay 3 – 300 Words)

Introduction:

Global warming is mainly a climate change resulting from human activities. Human activities form part of the climatic forcings that cause climate change. Human activities are external climatic forcings and they contribute to climate change more than the internal climatic forcings. Environmental pollution by human activities like industrialization, agricultural activities and fuel and energy generation processes like combustion. The pollutants that end up in the earth’s atmosphere cause changes in the components and processes in the atmosphere which eventually cause a change in climate.

Greenhouse Gases:

These are gases in the atmosphere that cause absorption and emission of radiation energy in the thermal infrared range. Greenhouse gases include water vapor, carbon dioxide, hydrofluorocarbons and ozone. An increase in concentration of these gases result in climate changes.

How human activities cause global warming:

Combustion of fossil fuels is a human activity that results in the largest emission of carbon dioxide gas to the atmosphere. Other greenhouse gases end up in the atmosphere due to release from factories and industries while unfiltered and untreated. These greenhouse gases in the atmosphere causes greenhouse effect through the destruction of layers of the atmosphere i.e., the ozone layer that regulates radiations and sun rays that get to the earth’s surface. Due to penetration of radiations and sunrays to the earth without regulation in terms of intensity, there will be an effect of raised temperatures which is referred to as global warming. The effect of pollutants in the atmosphere can either cause a cooling or a warming effect in the climate system.

Conclusion:

It is evident that human activities play a major role in global warming. The main activity is the release of greenhouse gases that cause the greenhouse effect which results in change of climate.


Essay on Role of Human Activities in Global Warming – For School Students (Class 6, 7, 8, 9, 10, 11 and 12 Standard) (Essay 4 – 400 Words)

Introduction:

Human activities in global warming are a great concern to all who love mother earth. The beautiful earth possessing all the essentials for a normal human life has been mistreated unknowingly for the past few centuries. With the onset of inventions and industrialization, which were considered boons for modern living, the livability of earth has deteriorated. Therefore, human activities in global warming and the resultant climate change has become cause of great concern for enthusiasts, who adore mother earth and care for the future generation.

Global Warming:

The Greenhouse Effect in the atmosphere maintains our earth at an optimum warm temperature. The greenhouse gases like Carbon dioxide, Nitrous Oxide, Methane and Chlorofluorocarbons (CFCs) form an enclosure in the atmosphere and prevent excess thermal energy from escaping into the atmosphere. But due to human activities like burning of fossil fuels, large amounts of greenhouse gases are released, they totally prohibit the escape of thermal energy into the atmosphere. This phenomenon results in the increase of earth’s temperature called Global Warming.

Human Activities:

Role of human activities in global warming contribute more than 75% as against natural phenomenon like gases released from volcano eruptions, smokes released from wildfires, emissions from radioactive substances and evaporations from volatile compounds.

One of the major role of human activities in global warming is the production of energy from fossil fuels. This energy is used in several modes of transportation, to operate various industries, generate power etc. All these activities result in emission of Carbon dioxide into the atmosphere.

Nature provides sufficient trees in every region to release oxygen for our survival. But human activities in global warming includes cutting down these trees for various purposes. They result in non-absorption of Carbon dioxide exhaled by us. It also reduces the availability of fresh source of oxygen breathed out by these trees.

The use of Nitrogen based fertilizers to promote agriculture is also seen as one of the role of human activities in global warming. Nitrogen gases from vehicle exhausts are a great source too. These activities release excess greenhouse gas Nitrous Oxide into the atmosphere.

Chlorofluorocarbons (CFCs) are extensively produced from cooling equipments, from aerosol spray cans, from production of polystyrene packing material etc. CFCs thus produced are found to destroy the ozone layer and have been detected as one of the role of human activities in global warming.

Studies further reveal that another greenhouse gas Methane gets released from paddy fields, garbage landfills etc.

These roles of human activities in global warming have ultimately resulted in flash floods, wildfires, droughts, hot summers, extremely cold winters, rising sea levels, melting snow on mountain tops, etc. They interrupt the normal life of human beings and other creatures of the earth.

Conclusion:

Role of human activities in global warming have caused year 2018 to set records in high temperatures and prolonged period of summers throughout the world. The Scientists at the Intergovernmental Panel on Climate Change (IPCC) have given suggestions to inhibit human activities in global warming. They promote insulating homes, eating local seasonal food, preventing wastage of food, walking or cycling frequently, avoiding car drive etc., in order to reduce carbon footprint at the personal level. These simple daily tasks would eventually lessen the role of human activities in global warming.


Essay on Role of Human Activities in Global Warming – With Remedies and Conclusion (Essay 5 – 500 Words)

Introduction:

In more than one instance human activities have proved to be nothing but harmful to nature. One such adverse effect inflicted on nature by humans is Global Warming. Quite often we hear the term Global Warming these days, but might not know the exact meaning. It simply means rise in surface temperature of our earth due to the emission of greenhouse gases like carbon dioxide, nitrous oxide, ozone and methane.

Enhanced Greenhouse Effect:

When sun’s rays reach the earth, some of it is reflected back to space and a bulk of it is absorbed by the earth’s surface. This absorption of sun’s heat warms up earth’s surface which in-turn radiates heat back to the atmosphere. This radiated heat is absorbed by greenhouse gases present in the atmosphere causing increase in temperature. This is a natural process which keeps temperature in check. However, the reason behind global warming is not greenhouse effect but it is enhanced greenhouse effect. When the concentration of greenhouse gases in the atmosphere increases than its norm, temperature increases above the necessary degree.

Role of Human Activities in Global Warming:

Several human activities cause increase in greenhouse gases in the atmosphere thus resulting in Global Warming.

1. Deforestation:

It is one of the major role of human activities in Global Warming. Trees absorb carbon dioxide and emit oxygen. Due to industrialization, mass destruction of trees around the globe takes place to provide for wood and paper. This naturally increases the amount of atmospheric carbon dioxide. This results in global warming.

2. Burning of Fossil Fuels:

To generate electricity and heat, large amounts of fossil fuels, oils and coal are being burned. This causes release of several greenhouse gases into the atmosphere which causes rise in atmospheric temperature thus resulting in Global Warming.

3. Farming:

Rearing of large flocks of sheep, goat and cow leads to emission of methane into the atmosphere. Also heavy use of chemical fertilizers results in the emission of nitrous oxide which is absorbs hundred fold more heat. This in turn leads to Global Warming that has adverse effects.

4. Plastic Waste:

Recycling of plastic waste releases harmful gases into the atmosphere. Burning of plastic waste is also toxic to our atmosphere. These accumulate and then lead to Global Warming.

5. Overpopulation:

All the above reasons are driven by one factor; population. Increase in human population leads to increase in demand for wood, paper, energy, meat, vegetables, fruits, spices and other natural foods and plastic products. This is also considered to be a major cause of Global Warming.

Remedies:

When these are known to be unavoidable circumstances in the world today, there are different ways to reduce the role of human activities in Global Warming as well. To avoid burning of fossil fuels and coal, greener forms of energy production like renewable energy should be preferred. This not only addresses enhanced greenhouse effect issue but also aids in making a cleaner and greener world thus pushing down the Global Warming affect to a much lower level.

Deforestation should be strictly punished and vast expanses of land should be allocated for new trees to be planted. Farmers should switch back to organic farming methods and completely eliminate the use of chemical fertilizers to keep our world green and clean. Use of plastics should not be encouraged. As much as possible, we should switch to greener solutions in every aspect of our lives. A small step taken initially can lead to a greener revolution thus reversing the Global Warming affect!

Conclusion:

God created humans to live in harmony with nature. Yet, we have only gone against nature in the name of advancement and science. It is high time we realise that nature has the ultimate say in things. Any negative impact we cause on nature will only reflect back to our living conditions. It is better late than never to take steps to work against Global Warming.


Essay on Role of Human Activities in Global Warming – For College and University Students (Essay 6 – 600 Words)

Human activities in global warming are only recently being accepted as a great contributing factor in the latest climate change. Even though scientists have been warning about the human activities in global warming and about their side effects on the climate for the past few decades, there is no big initiatives to resolve this global issue.

Non- Human Factors:

Some people will argue that there is no influence of human activities in global warming and that this climate change we are experiencing is just a natural phase in the earth warming and heating cycles. Such an opinion is not based on facts and scientist are showing us that the biggest contributors in this story are the human activities in global warming.

The volcanoes and other natural factors that could contribute to global warming cannot cause such a drastic rise in the surface temperature of the earth. After considering and measuring all the other potential sources for the drastic rise in temperature we are witnessing researchers became certain that none of the other factors come close to the influence of human activities in global warming.

Green House Gases:

Human activities in global warming are an issue because of the greenhouse gases that are produced daily. Everything that is linked with modern urban living contributes to the number of greenhouse gases that warm up the atmosphere and cause all of the drastic climate changes we are witnessing today. Human activities in global warming produce a lot of steam, carbon dioxide, methane, and such gases have the ability to radiate the heat they absorb from sunlight. Since human activities in global warming release a lot of those gases there are more molecules in the atmosphere that radiate heat and through this cause the global temperature to rise.

Climate Change:

Human activities in global warming have contributed to climate change and this can no longer be treated as a passing issue. Therefore, we all have a responsibility, even as students, to think about how we contribute to human activities in global warming. The thing is we have to plant the seeds of good habits in our practices from the beginning of our adult lives, through such discipline we can lessen the effects of climate change over time.

Human activities in global warming are the biggest contributor to global warming and this is because the issue is a systematic one. The only solution is to take a step back and to analyze the human activities in global warming from a new perspective and change our bad habits while we still have the time to make a real contribution.

Conclusion:

Questioning the notion of the influence of human activities in global warming have on the environment is without an effect. We should concentrate on what we can do to cut down on the human activities in global warming and to make the earth cool down because the other solution is to destroy our natural habitat and the planet that gave us life.

Human activities in global warming contribute to climate change and it also changes the general quality of life on earth. Over time the changes can cause drastic droughts and cause food shortages in different areas on the planet while it can also cause some other places to flood and destroy the entire cities.

Thinking about the human activities in global warming is an important lesson for every student regardless of what they are studying because this is not a problem that can be resolved just by the experts, each of us needs to pitch in and make their contribution.


Essay on Role of Human Activities in Global Warming – With Evidence, Preventive Steps and Conclusion (Essay 7 – 750 Words)

Earth’s surface has experienced uncommon warming since the earlier times, and particularly in this century. Each and every year since 1977 has been hotter than the twentieth century normal, with 16 of the 17 hottest years on record happening since 2001, and 2016 being the hottest year on written history. As an agriculturist can tell, the common attributes of the atmosphere have been altered. We realize that warming and cooling have occurred previously, and sometime before people even existed. Yet, what’s causing the present remarkable warming is there any role of human activities in global warming?

Evidence of Role of Human Activities in Global Warming:

It has been well established that the main gas contributing for the trapping of heat in the earth’s atmosphere is Carbon-dioxide. Researchers have long realized that ozone-harming substances in the environment, for example, carbon dioxide, methane, or water vapour retain certain frequencies of infrared radiation and dissipate them back toward the Earth. These gases basically keep warm from getting away rapidly again into space, catching that radiation at the surface and keeping the planet warm. This is a strong evidence of the role of human activities in global warming as deforestation has led to the increase in carbon-dioxide in the atmosphere.

Climate researchers additionally realize that convergences of ozone-depleting substances in the environment have developed essentially since the Industrial Revolution. The cooling systems such as air conditioners all use chlorofluro carbons (CFCs) which are responsible for the depletion of ozone layers covering the earth’s atmosphere. The excessive use of these CFCs has led to a hole in the ozone layer which protected us from the harmful infra-red rays of the sun. So it makes sense that more ozone-harming substances would prompt more warmth. What’s more, in reality, satellite estimations have demonstrated that less infrared radiation is getting away into space after some time and rather coming back to the Earth’s surface. That is solid proof about the role of human activities in global warming.

There are other evidence as well to establish the role of human activities in global warming. For example, the increase in pollution levels due to emissions from vehicles and industries has led to the trapping of harmful substances in the earth’s atmosphere. These substances not only increase the temperature on the earth but are harmful to humans and animals alike. In fact, there is a danger of many species being extinct due to this rise in temperature and pollution levels.

Preventive Steps Required:

There are a lot many steps which can be undertaken by us in order to reverse the role of human activities in global warming. First and foremost is to move on towards energy efficient sources and renewable sources of energy. The use of fossil fuels must be extremely reduced. Less use of chlorofluro carbons is another measure which can help in the reversal of the role of human activities in global warming. We must try and save whatever ozone layer is there so that we can protect ourselves from the harmful infra-red rays of the sun. Use of LED bulbs is another measure which can help in the contribution towards saving energy.

Last, but not least, we must reduce our dependency on vehicles. We must walk wherever we can, it serves a dual purpose. One, we remain healthy and second we save fuel and save the earth. Moreover, we can go for carpools as well wherever possible which again shall help us save fuels and earth alike. We can use electric vehicles as well which shall again help us save fossil fuels which are as on date being used in a catastrophe manner.

Conclusion:

A worldwide temperature alteration has turned into a long-term test that requires constant activity and speculation over decades. It is certainly not a day’s task to go back to the older days of good climate. It would likewise require different short and long-term measures by all the countries to achieve the objective. Measures are expected to enhance vitality effectiveness and advance the utilization of low-carbon fills.

The role of human activities in global warming has long been proved. The real move must be made against an unnatural weather change. Arrangements are required for vitality proficiency and to energize the utilization of fewer carbon powers. Utilization of sustainable power ought to be expanded. Reforestation rather than deforestation ought to be the objective. We all need to make efforts so that the role of human activities in global warming could be converted to the role of human activities in saving the planet. Planting trees are one of the least complex and successful approaches to do as such.


Essay on Role of Human Activities in Global Warming – Long Essay for Competitive Exams like IAS, IPS and UPSC (Essay 8 – 1000 Words)

The role of human activities in global warming is very essential. Global warming can simply be said to mean there is a temperature increases, it causes the earth (globe) to become warmer. Global warming is generally believed to be a result of greenhouse effect. Global warming is an extremely important issue that must be handled.

There has been a continual and exponential rise in the earth’s temperature some of the activities of man that contribute to global warming include overpopulation, deforestation, farming, fossil fuels burning and garbage. These human activities cause a release of various greenhouse gases into the environment and atmosphere which leads to global warming.

In other words, global warming is basically the rise of the mean temperature of the earth. We are prone to exploiting nature for our own personal and selfish benefits and we tend to neglect the environment and nature while doing this. This causes a lot of damage to the environment and global warming is one of the many effects.

There are some natural factors also along with some human activities that can be seen as responsible for global warming. Human beings are actually not the only contributors to global warming. In fact, global warming has been in existence long before the evolution of man. The sun largely determines the climate.

The earth’s temperature rises majorly when the energy entering the atmosphere from the sun is a lot more than the energy that bounces or goes back into the space. When solar activity reduces, the climate becomes colder than normal. Some other factors that are responsible include the eruption of volcanoes and many other forms of heat trapping substances and gases that are in the air or atmosphere.

The main human factors contributing to the climate are the emissions of heat trapping from oil and gas in cars and in the power plants, burning of coal, pollution from black carbon, the clearing of forests, etc. A major gas that brings harm to the atmosphere is carbon dioxide. Carbon dioxide is emitted when humans burn coal, fossil fuels and oils in order to produce energy that can be used for transport, powering of houses, television, smart phones and a lot if other devices. Some other gases of greenhouse include nitrous oxide, ozone and methane.

In order to fully battle global warming and its numerous dangers, some solutions and regulations must be out in place.

Some of the measures that can be put in place to help prevent and fight global warming are discussed below:

1. Stop Deforestation:

Deforestation is a major cause of global warming and accounts for a large amount of emission of heat trapping. Reducing or permanently stopping deforestation and also doing our best to help promote and encourage reforestation can go a long way to help in reducing global warming.

2. Using Renewable Sources as Energy Sources:

There are a lot of studies that have shown that the burning of some fossil fuels including gas, coal and oil increases the temperature of the atmosphere and the air through the release of various greenhouse gases into the atmosphere. A switch of energy sources to the renewable sources like wind, solar and hydropower can help in reducing the demand for energy sources that are fossil fuels. This will subsequently drop the emission rate of the greenhouse gases into the atmosphere and air.

3. An Economy of Clean Energy:

Investing in technologies and also industries that are energy efficient can go a long way in building an economy that has clean energy and this will help curtail global warming because the amount of greenhouse gases released into the atmosphere will drastically reduce.

4. Investment into Agriculture:

Some agricultural practices can help in reducing the release of methane and nitrous oxide into the air and atmosphere and these agricultural practices should be encouraged and improved by investing in them.

Having discussed some of the regulations that the government can put in place to fight global warming, it is very important to also look at some of the things that all of us as members of the society can do towards reducing Global Warming.

A few of the steps that can be taken to lower global warming are highlighted below:

1. Light bulbs that are fluorescent should be used instead of light bulbs that are incandescent because the light bulbs that are fluorescent consume about 25% energy when they are compared to the bulbs that are incandescent. LED technology and LED bulbs can also be used for lighting as they save a lot of electricity.

2. Electrical home appliances that are not in use should always be switched off when they are not in use so as to save electricity.

3. Fans can be used instead of using air conditioners as air conditioners use more energy than fans.

4. Only appliances that are energy efficient should be used at home.

5. We should endeavour to reuse and recycle things.

6. When packaging products, the minimum amount of packaging should be used.

7. Solar cookers can be used for cooking and heating systems can be converted into using solar energy.

8. The use of hybrid or electric cars should be encouraged instead of using gasoline cars. Government can also try to subsidise electric cars so that they are affordable.

9. Trees should be planted and there should be education about how planting of trees can help our environment by releasing oxygen and absorbing carbon dioxide.

10. We should try to reduce the lighting of our homes during the day. Sunlight from the windows and doors can serve as natural lighting.

11. We can save the quantity of water we consume by turning the tap off when we are brushing our teeth, reducing the period of time we spend under the shower and try to reduce the quantity and frequency of hot water we use.

12. We can also try to use the public transport more instead of using cars of our own as this would go a long way in reducing pollution by air and also save energy.
