Essay on Greenhouse Effect for Students and Children

500 words essay on greenhouse effect.

The past month, July of 2019, has been the hottest month in the records of human history. This means on a global scale, the average climate and temperatures are now seen a steady rise year-on-year. The culprits of this climate change phenomenon are mainly pollution , overpopulation and general disregard for the environment by the human race. However, we can specifically point to two phenomenons that contribute to the rising temperatures – global warming and the greenhouse effect. Let us see more about them in this essay on the greenhouse effect.

The earth’s surface is surrounded by an envelope of the air we call the atmosphere. Gasses in this atmosphere trap the infrared radiation of the sun which generates heat on the surface of the earth. In an ideal scenario, this effect causes the temperature on the earth to be around 15c. And without such a phenomenon life could not sustain on earth.

However, due to rapid industrialization and rising pollution, the emission of greenhouse gases has increased multifold over the last few centuries. This, in turn, causes more radiation to be trapped in the earth’s atmosphere. And as a consequence, the temperature on the surface of the planet steadily rises. This is what we refer to when we talk about the man-made greenhouse effect.

Causes of Greenhouse Effect

As we saw earlier in this essay on the greenhouse effect, the phenomenon itself is naturally occurring and an important one to sustain life on our planet. However, there is an anthropogenic part of this effect. This is caused due to the activities of man.

The most prominent among this is the burning of fossil fuels . Our industries, vehicles, factories, etc are overly reliant on fossil fuels for their energy and power. This has caused an immense increase in emissions of harmful greenhouse gasses such as carbon dioxide, carbon monoxide, sulfides, etc. This has multiplied the greenhouse effect and we have seen a steady rise in surface temperatures.

Other harmful activities such as deforestation, excessive urbanization, harmful agricultural practices, etc. have also led to the release of excess carbon dioxide and made the greenhouse effect more prominent. Another harmful element that causes harm to the environment is CFC (chlorofluorocarbon).

Some Effects of Greenhouse Effect

Even after overwhelming proof, there are still people who deny the existence of climate change and its devastating pitfalls. However, there are so many effects and pieces of evidence of climate change it is now undeniable. The surface temperature of the planet has risen by 1c since the 19th century. This change is largely due to the increased emissions of carbon dioxide. The most harm has been seen in the past 35 years in particular.

The oceans and the seas have absorbed a lot of this increased heat. The surfaces of these oceans have seen a rise in temperatures of 0.4c. The ice sheets and glaciers are also rapidly shrinking. The rate at which the ice caps melt in Antartica has tripled in the last decade itself. These alarming statistics and facts are proof of the major disaster we face in the form of climate change.

600 Words Essay on Greenhouse Effect

A Greenhouse , as the term suggests, is a structure made of glass which is designed to trap heat inside. Thus, even on cold chilling winter days, there is warmth inside it. Similarly, Earth also traps energy from the Sun and prevents it from escaping back. The greenhouse gases or the molecules present in the atmosphere of the Earth trap the heat of the Sun. This is what we know as the Greenhouse effect.

Greenhouse Gases

These gases or molecules are naturally present in the atmosphere of the Earth. However, they are also released due to human activities. These gases play a vital role in trapping the heat of the Sun and thereby gradually warming the temperature of Earth. The Earth is habitable for humans due to the equilibrium of the energy it receives and the energy that it reflects back to space.

Global Warming and the Greenhouse Effect

The trapping and emission of radiation by the greenhouse gases present in the atmosphere is known as the Greenhouse effect. Without this process, Earth will either be very cold or very hot, which will make life impossible on Earth.

The greenhouse effect is a natural phenomenon. Due to wrong human activities such as clearing forests, burning fossil fuels, releasing industrial gas in the atmosphere, etc., the emission of greenhouse gases is increasing.

Thus, this has, in turn, resulted in global warming . We can see the effects due to these like extreme droughts, floods, hurricanes, landslides, rise in sea levels, etc. Global warming is adversely affecting our biodiversity, ecosystem and the life of the people. Also, the Himalayan glaciers are melting due to this.

There are broadly two causes of the greenhouse effect:

I. Natural Causes

• Some components that are present on the Earth naturally produce greenhouse gases. For example, carbon dioxide is present in the oceans, decaying of plants due to forest fires and the manure of some animals produces methane , and nitrogen oxide is present in water and soil.
• Water Vapour raises the temperature by absorbing energy when there is a rise in the humidity.
• Humans and animals breathe oxygen and release carbon dioxide in the atmosphere.

II. Man-made Causes

• Burning of fossil fuels such as oil and coal emits carbon dioxide in the atmosphere which causes an excessive greenhouse effect. Also, while digging a coal mine or an oil well, methane is released from the Earth, which pollutes it.
• Trees with the help of the process of photosynthesis absorb the carbon dioxide and release oxygen. Due to deforestation the carbon dioxide level is continuously increasing. This is also a major cause of the increase in the greenhouse effect.
• In order to get maximum yield, the farmers use artificial nitrogen in their fields. This releases nitrogen oxide in the atmosphere.
• Industries release harmful gases in the atmosphere like methane, carbon dioxide , and fluorine gas. These also enhance global warming.

All the countries of the world are facing the ill effects of global warming. The Government and non-governmental organizations need to take appropriate and concrete measures to control the emission of toxic greenhouse gases. They need to promote the greater use of renewable energy and forestation. Also, it is the duty of every individual to protect the environment and not use such means that harm the atmosphere. It is the need of the hour to protect our environment else that day is not far away when life on Earth will also become difficult.

Global warming describes the current rise in the average temperature of Earth’s air and oceans. Global warming is often described as the most recent example of climate change . Earth’s climate has changed many times. Our planet has gone through multiple ice ages , in which ice sheets and glaciers covered large portions of Earth. It has also gone through warm periods when temperatures were higher than they are today. Past changes in Earth’s temperature happened very slowly, over hundreds of thousands of years. However, the recent warming trend is happening much faster than it ever has. Natural cycles of warming and cooling are not enough to explain the amount of warming we have experienced in such a short time—only human activities can account for it. Scientists worry that the climate is changing faster than some living things can adapt to it. In 1988, the World Meteorological Organization and the United Nations Environment Programme established a committee of climatologists , meteorologists , geographers , and other scientists from around the world. This Intergovernmental Panel on Climate Change (IPCC) includes thousands of scientists who review the most up-to-date research available related to global warming and climate change. The IPCC evaluates the risk of climate change caused by human activities. According to the IPCC’s most recent report (in 2007), Earth’s average surface temperatures have risen about 0.74 degrees Celsius (1.33 degrees Fahrenheit) during the past 100 years. The increase is greater in northern latitudes . The IPCC also found that land regions are warming faster than oceans. The IPCC states that most of the temperature increase since the mid-20th century is likely due to human activities. The Greenhouse Effect Human activities contribute to global warming by increasing the greenhouse effect. The greenhouse effect happens when certain gases—known as greenhouse gases —collect in Earth’s atmosphere . These gases, which occur naturally in the atmosphere, include carbon dioxide , methane , nitrogen oxide, and fluorinated gases sometimes known as chlorofluorocarbons (CFCs). Greenhouse gases let the sun’s light shine onto Earth’s surface, but they trap the heat that reflects back up into the atmosphere. In this way, they act like the insulating glass walls of a greenhouse. The greenhouse effect keeps Earth’s climate comfortable. Without it, surface temperatures would be cooler by about 33 degrees Celsius (60 degrees Fahrenheit), and many life forms would freeze . Since the Industrial Revolution in the late 1700s and early 1800s, people have been releasing large quantities of greenhouse gases into the atmosphere. That amount has skyrocketed in the past century. Greenhouse gas emissions increased 70 percent between 1970 and 2004. Emissions of carbon dioxide, the most important greenhouse gas, rose by about 80 percent during that time. The amount of carbon dioxide in the atmosphere today far exceeds the natural range seen over the last 650,000 years. Most of the carbon dioxide that people put into the atmosphere comes from burning fossil fuels such as oil , coal , and natural gas . Cars, trucks, trains, and planes all burn fossil fuels. Many electric power plants also burn fossil fuels. Another way people release carbon dioxide into the atmosphere is by cutting down forests . This happens for two reasons. Decaying plant material, including trees, releases tons of carbon dioxide into the atmosphere. Living trees absorb carbon dioxide. By diminishing the number of trees to absorb carbon dioxide, the gas remains in the atmosphere. Most methane in the atmosphere comes from livestock farming , landfills , and fossil fuel production such as coal mining and natural gas processing. Nitrous oxide comes from agricultural technology and fossil fuel burning. Fluorinated gases include chlorofluorocarbons, hydrochlorofluorocarbons , and hydrofluorocarbons. These greenhouse gases are used in aerosol cans and refrigeration. All of these human activities add greenhouse gases to the atmosphere, trapping more heat than usual and contributing to global warming. Effects of Global Warming Even slight rises in average global temperatures can have huge effects. Perhaps the biggest, most obvious effect is that glaciers and ice caps melt faster than usual. The meltwater drains into the oceans, causing sea levels to rise and oceans to become less salty. Ice sheets and glaciers advance and retreat naturally. As Earth’s temperature has changed, the ice sheets have grown and shrunk, and sea levels have fallen and risen. Ancient corals found on land in Florida, Bermuda, and the Bahamas show that the sea level must have been five to six meters (16-20 feet) higher 130,000 years ago than it is today. Earth doesn’t need to become oven-hot to melt the glaciers. Northern summers were just three to five degrees Celsius (five to nine degrees Fahrenheit) warmer during the time of those ancient fossils than they are today. However, the speed at which global warming is taking place is unprecedented . The effects are unknown. Glaciers and ice caps cover about 10 percent of the world’s landmass today. They hold about 75 percent of the world’s fresh water. If all of this ice melted, sea levels would rise by about 70 meters (230 feet). The IPCC reported that the global sea level rose about 1.8 millimeters (0.07 inches) per year from 1961 to 1993, and 3.1 millimeters (0.12 inches) per year since 1993. Rising sea levels could flood coastal communities, displacing millions of people in areas such as Bangladesh, the Netherlands, and the U.S. state of Florida. Forced migration would impact not only those areas, but the regions to which the “ climate refugees ” flee . Millions more people in countries like Bolivia, Peru, and India depend on glacial meltwater for drinking, irrigation , and hydroelectric power . Rapid loss of these glaciers would devastate those countries. Glacial melt has already raised the global sea level slightly. However, scientists are discovering ways the sea level could increase even faster. For example, the melting of the Chacaltaya Glacier in Bolivia has exposed dark rocks beneath it. The rocks absorb heat from the sun, speeding up the melting process. Many scientists use the term “climate change” instead of “global warming.” This is because greenhouse gas emissions affect more than just temperature. Another effect involves changes in precipitation like rain and snow . Patterns in precipitation may change or become more extreme. Over the course of the 20th century, precipitation increased in eastern parts of North and South America, northern Europe, and northern and central Asia. However, it has decreased in parts of Africa, the Mediterranean, and parts of southern Asia. Future Changes Nobody can look into a crystal ball and predict the future with certainty. However, scientists can make estimates about future population growth, greenhouse gas emissions, and other factors that affect climate. They can enter those estimates into computer models to find out the most likely effects of global warming. The IPCC predicts that greenhouse gas emissions will continue to increase over the next few decades . As a result, they predict the average global temperature will increase by about 0.2 degrees Celsius (0.36 degrees Fahrenheit) per decade. Even if we reduce greenhouse gas and aerosol emissions to their 2000 levels, we can still expect a warming of about 0.1 degree Celsius (0.18 degrees Fahrenheit) per decade. The panel also predicts global warming will contribute to some serious changes in water supplies around the world. By the middle of the 21st century, the IPCC predicts, river runoff and water availability will most likely increase at high latitudes and in some tropical areas. However, many dry regions in the mid-latitudes and tropics will experience a decrease in water resources. As a result, millions of people may be exposed to water shortages . Water shortages decrease the amount of water available for drinking, electricity , and hygiene . Shortages also reduce water used for irrigation. Agricultural output would slow and food prices would climb. Consistent years of drought in the Great Plains of the United States and Canada would have this effect. IPCC data also suggest that the frequency of heat waves and extreme precipitation will increase. Weather patterns such as storms and tropical cyclones will become more intense. Storms themselves may be stronger, more frequent, and longer-lasting. They would be followed by stronger storm surges , the immediate rise in sea level following storms. Storm surges are particularly damaging to coastal areas because their effects (flooding, erosion , damage to buildings and crops) are lasting. What We Can Do Reducing our greenhouse gas emissions is a critical step in slowing the global warming trend. Many governments around the world are working toward this goal. The biggest effort so far has been the Kyoto Protocol , which was adopted in 1997 and went into effect in 2005. By the end of 2009, 187 countries had signed and ratified the agreement. Under the protocol , 37 industrialized countries and the European Union have committed to reducing their greenhouse gas emissions. There are several ways that governments, industries, and individuals can reduce greenhouse gases. We can improve energy efficiency in homes and businesses. We can improve the fuel efficiency of cars and other vehicles. We can also support development of alternative energy sources, such as solar power and biofuels , that don’t involve burning fossil fuels. Some scientists are working to capture carbon dioxide and store it underground, rather than let it go into the atmosphere. This process is called carbon sequestration . Trees and other plants absorb carbon dioxide as they grow. Protecting existing forests and planting new ones can help balance greenhouse gases in the atmosphere. Changes in farming practices could also reduce greenhouse gas emissions. For example, farms use large amounts of nitrogen-based fertilizers , which increase nitrogen oxide emissions from the soil. Reducing the use of these fertilizers would reduce the amount of this greenhouse gas in the atmosphere. The way farmers handle animal manure can also have an effect on global warming. When manure is stored as liquid or slurry in ponds or tanks, it releases methane. When it dries as a solid, however, it does not. Reducing greenhouse gas emissions is vitally important. However, the global temperature has already changed and will most likely continue to change for years to come. The IPCC suggests that people explore ways to adapt to global warming as well as try to slow or stop it. Some of the suggestions for adapting include:

• Expanding water supplies through rain catchment , conservation , reuse, and desalination .
• Adjusting crop locations, variety, and planting dates.
• Building seawalls and storm surge barriers and creating marshes and wetlands as buffers against rising sea levels .
• Creating heat-health action plans , boosting emergency medical services, and improving disease surveillance and control.
• Diversifying tourism attractions, because existing attractions like ski resorts and coral reefs may disappear.
• Planning for roads and rail lines to cope with warming and/or flooding.
• Strengthening energy infrastructure , improving energy efficiency, and reducing dependence on single sources of energy.

Barking up the Wrong Tree Spruce bark beetles in the U.S. state of Alaska have had a population boom thanks to 20 years of warmer-than-average summers. The insects have managed to chew their way through 1.6 million hectares (four million acres) of spruce trees.

Disappearing Penguins Emperor penguins ( Aptenodytes forsteri ) made a showbiz splash in the 2005 film March of the Penguins . Sadly, their encore might include a disappearing act. In the 1970s, an abnormally long warm spell caused these Antarctic birds' population to drop by 50 percent. Some scientists worry that continued global warming will push the creatures to extinction by changing their habitat and food supply.

Shell Shock A sudden increase in the amount of carbon dioxide in the atmosphere does more than change Earth's temperature. A lot of the carbon dioxide in the air dissolves into seawater. There, it forms carbonic acid in a process called ocean acidification. Ocean acidification is making it hard for some sea creatures to build shells and skeletal structures. This could alter the ecological balance in the oceans and cause problems for fishing and tourism industries.

Climate Change Sample Essay 250 Words

Climate change represents a pressing global challenge that demands immediate attention and concerted efforts. Human activities, primarily the burning of fossil fuels and deforestation, have significantly increased the concentration of greenhouse gases in the atmosphere. This results in a greenhouse effect, trapping heat and leading to a rise in global temperatures, commonly referred to as global warming.

The consequences of climate change are far-reaching and profound. Rising sea levels threaten coastal communities, displacing millions and endangering vital infrastructure. Extreme weather events, such as hurricanes, droughts, and wildfires, have become more frequent and severe, causing devastating economic and human losses. Disrupted ecosystems affect biodiversity and the availability of vital resources, from clean water to agricultural yields.

Moreover, climate change has serious implications for food and water security. Changing weather patterns disrupt traditional farming practices and strain freshwater resources, potentially leading to conflicts over access to essential commodities.

Addressing climate change necessitates a multifaceted approach. First, countries must reduce their greenhouse gas emissions through the transition to renewable energy sources, increased energy efficiency, and reforestation efforts. International cooperation is crucial to set emission reduction targets and hold nations accountable for meeting them.

In conclusion, climate change is a global crisis with profound and immediate consequences. Urgent action is needed to mitigate its impacts and secure a sustainable future for our planet. By reducing emissions and implementing adaptation strategies, we can protect vulnerable communities, preserve ecosystems, and ensure a livable planet for future generations. The time to act is now.

Essay on Climate Change

Climate Change Essay - The globe is growing increasingly sensitive to climate change. It is currently a serious worldwide concern. The term "Climate Change" describes changes to the earth's climate. It explains the atmospheric changes that have occurred across time, spanning from decades to millions of years. Here are some sample essays on climate change.

100 Words Essay on Climate Change

200 words essay on climate change, 500 words essay on climate change.

The climatic conditions on Earth are changing due to climate change. Several internal and external variables, such as solar radiation, variations in the Earth's orbit, volcanic eruptions, plate tectonics, etc., are to blame for this.

There are strategies for climate change reduction. If not implemented, the weather might get worse, there might be water scarcity, there could be lower agricultural output, and it might affect people's ability to make a living. In order to breathe clean air and drink pure water, you must concentrate on limiting human activity. These are the simple measures that may be taken to safeguard the environment and its resources.

The climate of the Earth has changed significantly over time. While some of these changes were brought on by natural events like volcanic eruptions, floods, forest fires, etc., many of the changes were brought on by human activity. The burning of fossil fuels, domesticating livestock, and other human activities produce a significant quantity of greenhouse gases. This results in an increase of greenhouse effect and global warming which are the major causes for climate change.

Reasons of Climate Change

Some of the reasons of climate change are:

Deforestation

Excessive use of fossil fuels

Water and soil pollution

Plastic and other non biodegradable waste

Wildlife and nature extinction

Consequences of Climate Change

All kinds of life on earth will be affected by climate change if it continues to change at the same pace. The earth's temperature will increase, the monsoon patterns will shift, the sea level will rise, and there will be more frequent storms, volcano eruptions, and other natural calamities. The earth's biological and ecological equilibrium will be disturbed. Humans won't be able to access clean water or air to breathe when the environment becomes contaminated. The end of life on this earth is imminent. To reduce the issue of climate change, we need to bring social awareness along with strict measures to protect and preserve the natural environment.

A shift in the world's climatic pattern is referred to as climate change. Over the centuries, the climate pattern of our planet has undergone modifications. The amount of carbon dioxide in the atmosphere has significantly grown.

When Did Climate Change Begin

It is possible to see signs of climate change as early as the beginning of the industrial revolution. The pace at which the manufacturers produced things on a large scale required a significant amount of raw materials. Since the raw materials being transformed into finished products now have such huge potential for profit, these business models have spread quickly over the world. Hazardous substances and chemicals build up in the environment as a result of company emissions and waste disposal.

Although climate change is a natural occurrence, it is evident that human activity is turning into the primary cause of the current climate change situation. The major cause is the growing population. Natural resources are utilised more and more as a result of the population's fast growth placing a heavy burden on the available resources. Over time, as more and more products and services are created, pollution will eventually increase.

Causes of Climate Change

There are a number of factors that have contributed towards weather change in the past and continue to do so. Let us look at a few:

Solar Radiation |The climate of earth is determined by how quickly the sun's energy is absorbed and distributed throughout space. This energy is transmitted throughout the world by the winds, ocean currents etc which affects the climatic conditions of the world. Changes in solar intensity have an effect on the world's climate.

Deforestation | The atmosphere's carbon dioxide is stored by trees. As a result of their destruction, carbon dioxide builds up more quickly since there are no trees to absorb it. Additionally, trees release the carbon they stored when we burn them.

Agriculture | Many kinds of greenhouse gases are released into the atmosphere by growing crops and raising livestock. Animals, for instance, create methane, a greenhouse gas that is 30 times more potent than carbon dioxide. The nitrous oxide used in fertilisers is roughly 300 times more strong than carbon dioxide.

How to Prevent Climate Change

We need to look out for drastic steps to stop climate change since it is affecting the resources and life on our planet. We can stop climate change if the right solutions are put in place. Here are some strategies for reducing climate change:

Raising public awareness of climate change

Prohibiting tree-cutting and deforestation.

Ensure the surroundings are clean.

Refrain from using chemical fertilisers.

Water and other natural resource waste should be reduced.

Protect the animals and plants.

Purchase energy-efficient goods and equipment.

Increase the number of trees in the neighbourhood and its surroundings.

Follow the law and safeguard the environment's resources.

Reduce the amount of energy you use.

During the last few decades especially, climate change has grown to be of concern. Global concern has been raised over changes in the Earth's climatic pattern. The causes of climate change are numerous, as well as the effects of it and it is our responsibility as inhabitants of this planet to look after its well being and leave it in a better condition for future generations.

Essay On Global Warming

Essay on global warming is an important topic for students to understand. The essay brings to light the plight of the environment and the repercussion of anthropogenic activities. Continue reading to discover tips and tricks for writing an engaging and interesting essay on global warming.

Essay On Global Warming in 300 Words

Global warming is a phenomenon where the earth’s average temperature rises due to increased amounts of greenhouse gases. Greenhouse gases such as carbon dioxide, methane and ozone trap the incoming radiation from the sun. This effect creates a natural “blanket”, which prevents the heat from escaping back into the atmosphere. This effect is called the greenhouse effect.

Contrary to popular belief, greenhouse gases are not inherently bad. In fact, the greenhouse effect is quite important for life on earth. Without this effect, the sun’s radiation would be reflected back into the atmosphere, freezing the surface and making life impossible. However, when greenhouse gases in excess amounts get trapped, serious repercussions begin to appear. The polar ice caps begin to melt, leading to a rise in sea levels. Furthermore, the greenhouse effect is accelerated when polar ice caps and sea ice melts. This is due to the fact the ice reflects 50% to 70% of the sun’s rays back into space, but without ice, the solar radiation gets absorbed. Seawater reflects only 6% of the sun’s radiation back into space. What’s more frightening is the fact that the poles contain large amounts of carbon dioxide trapped within the ice. If this ice melts, it will significantly contribute to global warming. 

A related scenario when this phenomenon goes out of control is the runaway-greenhouse effect. This scenario is essentially similar to an apocalypse, but it is all too real. Though this has never happened in the earth’s entire history, it is speculated to have occurred on Venus. Millions of years ago, Venus was thought to have an atmosphere similar to that of the earth. But due to the runaway greenhouse effect, surface temperatures around the planet began rising. 

If this occurs on the earth, the runaway greenhouse effect will lead to many unpleasant scenarios – temperatures will rise hot enough for oceans to evaporate. Once the oceans evaporate, the rocks will start to sublimate under heat. In order to prevent such a scenario, proper measures have to be taken to stop climate change.

What is the greenhouse effect?

The greenhouse effect is the process through which heat is trapped near Earth's surface by substances known as 'greenhouse gases.' Imagine these gases as a cozy blanket enveloping our planet, helping to maintain a warmer temperature than it would have otherwise. Greenhouse gases consist of carbon dioxide, methane, ozone, nitrous oxide, chlorofluorocarbons, and water vapor. Water vapor, which reacts to temperature changes, is referred to as a 'feedback', because it amplifies the effect of forces that initially caused the warming.

Scientists have determined that carbon dioxide plays a crucial role in maintaining the stability of Earth's atmosphere. If carbon dioxide were removed, the terrestrial greenhouse effect would collapse, and Earth's surface temperature would drop significantly, by approximately 33°C (59°F).

Greenhouse gases are part of Earth's atmosphere. This is why Earth is often called the 'Goldilocks' planet – its conditions are just right, not too hot or too cold, allowing life to thrive. Part of what makes Earth so amenable is its natural greenhouse effect, which maintains an average temperature of 15 ° C (59 ° F) . However, in the last century, human activities, primarily from burning fossil fuels that have led to the release of carbon dioxide and other greenhouse gases into the atmosphere, have disrupted Earth's energy balance. This has led to an increase in carbon dioxide in the atmosphere and ocean. The level of carbon dioxide in Earth’s atmosphere has been rising consistently for decades and traps extra heat near Earth's surface, causing temperatures to rise.

Essay on Greenhouse Effect: Causes, Problems, Effects and Prevention

The process by which radiation from a planet’s atmosphere warms its surface to a temperature which exceeds the normal temperature of the planet is called greenhouse effect. If a planet’s atmosphere contains greenhouse gases, the atmosphere will radiate the energy in various directions. Some part of this radiation will be towards the surface, making it warm. The downward component of the radiation, which is the strength of the greenhouse effect will depend on the atmosphere’s temperature and amount of greenhouse gases present in the atmosphere.

The earth’s atmosphere is warmed by absorbing infrared thermal radiation from the sun. The greenhouse gases which are present in the atmosphere radiate energy, some of which is directed to the surface and lower atmosphere. The mechanism which produces this difference between the actual surface temperature and effective temperature is due to the temperature, knows as greenhouse effect.

The natural greenhouse effect of the earth is critical to support life. Human activities such as burning the fossil fuels and clearing the forests have made an intense impact on natural greenhouse effect, leading to global warming.

History of Greenhouse Effect

The term greenhouse effect was first used by atmospheric scientists in early 1800s. The existence of greenhouse effect was brought up by Joseph Fourier in 1824. In 1896, the effect was fully qualified by Svante Arrhenius, who made the first quantitative prediction of global warming because of a hypothetical doubling of atmospheric carbon dioxide. At the time, it was used to describe the naturally occurring functions of greenhouse gases present in the atmosphere, and did not have any negative subtexts. It was not until the mid 1950s that greenhouse effect was teamed with concern for climate change.

Greenhouse gases that cause Greenhouse Effect

The major gases which contribute to the greenhouse effect on earth are as follows:-

• Water vapor 36-70%
• Carbon dioxide 9-26%
• Methane 4-9%

The below mentioned activities release gases which prove to be harmful for the planet. Following are the six major greenhouses which play a lead role in the greenhouse effect and global warming:-

1. Carbon dioxide (CO2)

It is a naturally occurring gas, produced by living organisms and fermentation. Carbon dioxide which is emitted from fuel burning is responsible for approx 87% of global warming, and has alarmingly increased by 27% since the industrial revolution.

2. Methane (CH4)

Methane is a naturally occurring inflammable gas which is produced by decomposition of organic matters and geological coal formations. The landfills hole the major credit to release methane, which adds up into the atmosphere and leads the global warming.

3. Nitrogen oxides (NOx)

Nitrogen oxides are naturally occurring from microbial action present in the soil. It is also produced by burning of fuels. Due to the increased use of nitrogen based fertilizers and catalytic converters in automobiles, the production of nitrogen oxides has raised, thus disturbing the ecosystem balance.

4. Hydrofluorocarbon gases (HFCs)

Chlorofluorocarbons (CFCs), coolant, cleaning and propellant gases were blacklisted internationally due to its harmful effect on the ozone layer. HFCs also play a crucial part in global warming, and are 4,000 to 10,000 times more harmful than carbon dioxide.

5. Sulphur hexafluoride (SF6)

Very low atmospheric concentration can make it a good test gas for gas concentration monitors. SF6 is a man-made gas used in water leakage detection for cable cooling systems and insulating materials for high voltage equipment.

6. Perfluorocrbons (PFCs)

PFCs are man-made replacement gases for CFCs, but they also result as a by-product of aluminum smelting. They are also used as a purging agent for semi conductor manufacturing. They cause severe damage to the atmosphere too.

What does increased greenhouse gases indicate?

The increase in greenhouse gases directly increases the heat on the planet’s surface and lower atmosphere. It has a dangerous effect as it can reduce or even create holes in the ozone layer. Due to this, harmful rays such as ultra violet rays can seep in though the thin areas and cause damage on earth.

What are the causes of greenhouse effect?

1. burning the fossil fuels.

Fossil fuels such as coal, natural gas and oil are an integral part of our lives, the elements which play a vital role in daily routines. The most important use of fossil fuels occurs in producing electricity and transportation. On burning the fossil fuels, the carbon dioxide stored inside them is released, which combines with oxygen in the air, resulting in production of carbon dioxide. As the population is increasing, the numbers of vehicles have made a high leap too. Due to this, the pollution has increased in the atmosphere. As these vehicles run, carbon dioxide is released, which is one of the main gases responsible for increase in greenhouse effect.

Electricity related emissions are high because we are still dependant on coal for generating electricity, which releases a huge amount of carbon dioxide into the atmosphere. Since it is the primary source of generating electricity, the loss of fossil fuels is massive, due to which the global warming has increased.

2. Deforestation

A major section of the land on our earth is covered by the forests. They are very important for a sustainable life on earth, as plants give out oxygen and inhale the carbon dioxide. Thus, the ecosystem is balanced due to the presence of trees. Sadly, large scale development of the urban landscapes has resulted in depletion of green cover of the earth. Forests are now being burnt down or chopped off to build concrete buildings instead. On burning the wood, the stored carbon is converted back to carbon dioxide, which adds up into the atmosphere, increasing the pollution.

3. Industrial waste and landfills

Various industries which are involved in cement production, fertilizers, extraction of oil, coal mining activities etc produce harmful greenhouse gases. Also, landfills filled with garbage produce carbon dioxide and methane, which play a major role in the greenhouse effect.

4. Population rise

Increase in population over the decades has led to high demand for food, clothing and shelter. Machines used in our daily lives such as air conditioners also exhale harmful gases, which contribute to the greenhouse effect. Also, more number of people means more usage of fossil fuels, which has made the situations much worse.

What are the harmful effects of greenhouse effect?

The adverse effects of greenhouse effect are alarming. They are already being experienced on the earth now, and can go much adverse changes in the near future. The major harmful effects of greenhouse effect are listed below:

• The sea levels will rise. There is more than 5,773,000 cubic miles of water present in form of ice caps, glaciers and permanent snow. According to the National Snow and Ice Data Center, if all of the glaciers met, the sea level would rise by 230 feet! This will not happen all at once, but the levels will rise certainly, submerging the low-lying areas.
• The balance of the global ecosystem will be affected. The fresh water stored in the ice caps will desalinate the ocean as they melt. The desalination in the gulf current will play a negative impact on the ocean currents, which regulate temperatures. It will be difficult to draw a pattern of warming and cooling in some areas.
• Warmer water and stronger hurricanes will be more frequent than now. Due to the rise in oceans’ temperature, the probability of frequent and stronger hurricanes may also become a threat.
• Weather patterns will continue to change. Most of the regions that are currently subjected to droughts will face much challenging conditions. The wet region will get wetter too. Mountain glaciers and snow caps will further shrink which will jeopardize many water supply systems. These negative changes have already begun to show their impact in some parts of the world.
• Ecosystems will be stressed due the impact of greenhouse effect and global warming. Flora and fauna will be massively affected. The animals which cannot adapt to the climatic changes will extinct over the time, thus misbalancing the ecosystem balance. A variety of pests and tropical diseases are expected to sprout in the warmer regions. Valuable species especially in the arctic will be the worst affected.

Evidence to the changes in earth’s climate: Global Warming

The effects of greenhouse effect and global warming have already started showing up in some parts of the world. Situations are predicted to get much worse. Some of the observations recorded by the Intergovernmental Panel on Climate Change (IPCC) are as follows: -

• Eleven out of twelve warmest years since 1850 occurred between 1996 and 2006. Average global temperatures have risen by approximately 0.74C between 1906 and 2005. This rise in temperature is widespread throughout the world, but higher at the northern latitudes.
• Sea levels have increased during the same period. Since 1961, the average rate has been 1.8 mm per year, but has now further increased to 3.1 mm per year since 1993.
• Some of the climate changes agencies from the United States have reported that the oceans all over the world are getting warmer at a rate much higher than predicted. The warming has occurred approximately 50% faster over that last century, than it was calculated previously.

A number of human activities contribute to the greenhouse effect, which has brought us to the alarming situations today. If continued without taking precautions to save the earth, the situations are going to be worse. Some of the human activities which produce greenhouse gases are as follows: -

• Fuel combustion
• Vehicle transport and automobiles
• Energy industries
• Use of oil and natural gas
• Metal production manufacturing industries and construction
• Fugitive emissions from fuels
• Mineral products
• Chemical industries
• Production of halocarbons
• Solvent and other product use
• Consumption of halocarbons and sulphur hexafluoride
• Production of halocarbons and sulphur hexafluoride
• Enteric fermentation
• Rice cultivation
• Agricultural soils
• Prescribes burning of savannas
• Solid waste disposal on land
• Wastewater handling
• Waste incineration
• Field burning of agricultural residues

What preventive should be taken against greenhouse effect?

It would not be late today if we take an initiative to make the earth a reliable place to live in. to reduce the harmful effects of greenhouse gases on the earth and atmosphere, change must be brought in our daily routine and lifestyles. Here are some of the best suggestive steps to keep in mind to reduce greenhouse gas emissions:-

• Reduce, Reuse, Recycle Following the three Rs in your daily life can make a difference too. Buying products with minimal packaging will help in reducing waste. Through recycling half of your household waste, 2,400 pounds of carbon dioxide can be saved from adding up in the atmosphere.
• By adding insulation to the walls, installing caulking or weather stripping around doors and windows.
• Lower the heat while sleeping and keep the temperature moderate all the time.
• Installing a programmable thermostat can save a large amount of carbon dioxide from being released. By setting it just 2 degrees lower during winter and higher in summer can save approx. 2,000 pounds of carbon dioxide each year.
• Replace the light bulbs with Compact Fluorescent Lights It is better to use compact fluorescent light (CFL) than the usual light bulbs. By replacing just one 60-watt incandescent light bulb with a CFL, over $30 will be saved over the life of the bulb. Also, the CFL gives off 70 percent less heat than the light bulbs and lasts 10 times longer than them too.
• Drive less and drive smart Walking and biking are a great form of exercise. Not only they will keep you fit, but also make your contribution towards saving the planet, since less driving means lesser emissions. Every gallon of gas saved will keep 20 pounds of carbon dioxide away from the atmosphere.
• Use less hot water Set your water heater at 120 degrees and wrap it in an insulating blanket if it is 15 years old. Also, use low flow showerheads to save hot water and approx 350 pounds of carbon dioxide every year.
• Buy energy efficient products Home appliances now come in a wide range of energy efficient models, and compact fluorescent bulbs are designed to use much lesser amount of energy than the regular light bulbs.
• Plant a tree Trees are the best solution to fight against the greenhouse effect and global warming. Not only they inhale carbon dioxide and release oxygen for us, plantation will also help in restoring the disturbed ecological balance.
• Use the ‘off’ switch Save electricity and reduce global warming by using power only when you need it. Make a habit to switch off lights, television, computer and other electronic devices when they are not in use. Turn off the water tap when you do not need the water. These simple steps will help you in reducing the energy usage and burning of fossil fuels. Less energy usage means less dependence on fossil fuels, which on burning contribute to the harmful greenhouse effect.

Greenhouse effect Essay Conclusion

Greenhouse effect and global warming are the biggest threat to human race and the biggest environmental challenge of 21st century that we need to tackle. It is important for all citizens to become fully aware of the causes and harmful consequences of greenhouse effect and global warming. The main culprits of greenhouse effect and global warming is the growing emission of harmful gases such as Methane, carbon dioxide and carbon monoxide resulting from emissions of industrial activities, incomplete combustion of petrol and diesel from vehicles as well as growing emissions of CFCs from air conditioners. It is important for individuals to choose greener alternatives such as cycling, hybrid clean fuels and for industries and governments to choose environmental friendly production methods and energy sources. Immediate action on this greenhouse effect and global warming is necessary to tackle this environmental problem.
