What is greenhouse effect & How does work? | Major causes

What is greenhouse effect? There is a lot of discussion about this from the farmer adopting the modern farming system to the big scientist. A greenhouse is a building made of glass or plastic, which is used especially for growing plants. Greenhouses work to maintain temperature balance. This is a human-made artificial greenhouse, but the various gases present in the atmosphere around the earth act like greenhouses. Which we know as greenhouse gases.

What is greenhouse effect 

Greenhouse gases present in the Earth's atmosphere work to maintain the temperature balance in the Earth's environment. About 29 percent of solar energy coming from the Sun is reflected back to space by reflecting clouds, atmospheric particles, or shiny ground surfaces such as sea ice and snow. About 23 percent is absorbed into the Earth's atmosphere, and 48 percent is absorbed by the surface passing through the atmosphere. Overall, about 71 percent of the incoming solar energy plays a role in the Earth's climate system.

What is the role of the greenhouse effect in the Earth's climate system? Does the greenhouse effect cause solar energy to be absorbed into the atmosphere? Such questions will definitely arise in your mind. In this article, we will discuss in detail about these questions, along with answering these questions, what is the greenhouse effect, how does it work, etc. So let's first know what is greenhouse effect.

What is Greenhouse Effect?

The "greenhouse effect" is a natural process that keeps the Earth's surface warm. In this process, molecules of greenhouse gases present in the Earth's atmosphere absorb solar energy and produce heat that keeps the Earth's surface and atmosphere warm. The more greenhouse gases are concentrated in the atmosphere, the more heat is locked into the molecules.

Greenhouse gases are produced naturally and become part of our environment. The part that makes the Earth indelible to us is a naturally occurring greenhouse effect, which on average maintains the planet at 15 ° C (59 ° F). But in the last century, the increase in excess carbon dioxide in the air due to human activity has greatly interfered with the planet's energy balance. Because of which greenhouse gases are continuously increasing in the Earth's atmosphere, due to which the temperature is increasing day by day.


In 1824 Joseph Fuhrer first told about the greenhouse effect. He calculated that if there was no atmosphere, the Earth would have been colder. The arguments and evidence he gave were further strengthened by Claude Paulet in the years 1827 and 1838. John Tindall gave this reason in 1859 after experimenting and observing it. But in 1896 Swante Arrhenius first gave clear quantitative information by making quantitative forecasts. But no scientist had used the term greenhouse. The term was first used by Nils Gustaf Ekholm in 1901.

In 1895, Swedish chemist Svante Arrhenius reported that humans can increase the greenhouse effect by creating carbon dioxide and other greenhouse gases.

How does the greenhouse effect work?

In the modern agricultural system, the greenhouse of glass or plastic works to maintain the temperature balance. In the same way, the greenhouse gases present in the earth's atmosphere acts as a layer, which maintains the temperature balance on the earth.

The greenhouse used for plants is warm inside even during winter. In the daytime, sunlight shines in the greenhouse and heats the plants and the air. At night, it is cold outside, but the greenhouse remains very hot inside. This is because the glass walls of the greenhouse trap the heat of the sun.

In the same way, the greenhouse effect works on earth. During the day, the sun shines in the atmosphere. Earth's surface is warmed by sunlight. At night, the Earth's surface cools down, releasing heat back into the air. But some heat is trapped in the atmosphere by greenhouse gases. This is the reason why our Earth is on average 58 degrees Fahrenheit (14 degrees Celsius) warm and comfortable.

Major causes of greenhouse effect

Some of the main causes of the greenhouse effects are as follows:

Natural reason:

• Due to some elements naturally present on the earth, such as carbon dioxide found in the sea and methane which is produced by the decay of trees and natural fires, and nitrogen oxides which are found in some amount in land and water Greenhouse gases are manufactured. Only fluorinated gases are produced by humans, which are not naturally present in nature.

• Water vapor also contributes greatly to the greenhouse effect. Thermal energy is absorbed by the water vapor, most often when air is increased in volatility. So due to this, the temperature in the atmosphere also increases.

• Oxygen is taken from the atmosphere by animals and emits carbon dioxide and methane gas. It is one of the natural factors of the greenhouse effect.

Man-made reasons

• Combustion of fossil fuels such as oil and coal also contributes significantly to greenhouse effects. Burning fossil fuels also emit carbon dioxide into the atmosphere, which pollutes the atmosphere. Apart from this, digging of gas and coal mines and oil wells also emits methane gas.

• Deforestation is another major cause of the greenhouse effect. Plants also play an important role in reducing the amount of carbon dioxide in the environment and providing oxygen.

• Naturally made nitrogen which is used as fertilizer in crops. This emits nitrogen oxides in the atmosphere, thereby increasing the greenhouse effect.

• Very heavy industrial gases are emitted into the atmosphere throughout the world. Gases such as methane, carbon dioxide, and fluorine gas fall into the category of industrial gases.

• Agriculturally domesticated animals such as goats, pigs, cows, etc. also contribute significantly to the emission of greenhouse gases. When their food is digested by these animals, then methane gas is produced in their paint, which gets mixed into the atmosphere when they are dung. Harvesting of forests to create more farms for domesticated animals has also increased the emission of greenhouse gases.

Greenhouse effect on climate

Climate is dramatically affected by the emission of greenhouse gases in the atmosphere. Since the time of industrialization, the emission of many types of greenhouse gases in the atmosphere has increased considerably. Greenhouse gases arise from the combustion of most fossil fuels. Carbon dioxide (CO), water vapor (HO), methane (CH), ozone (O), nitrous oxide (NO), etc. are gases that enhance the greenhouse effect.

Greenhouse gases have the highest amount of CO and have increased up to 40% since the start of industrialization. As such, natural processes can absorb gases in the atmosphere. For example, the process of photosynthesis can absorb carbon dioxide, but due to the gradual increase in the amount of these gases, nature's ability to absorb them is decreasing. The imbalance between the emission of greenhouse gases and the ability to absorb gases has led to an acute increase in the emission of greenhouse gases in the atmosphere.

We have burned a lot of fossils fuels and our atmosphere has been polluted with poisonous gases due to the massive tree harvesting, massive methane generated by pets. Greenhouse gases, which absorb large amounts of radiation, due to their large presence in the atmosphere, have caused major problems like climate change and at present, global warming is the biggest problem faced by mankind.

Conclusion: The greenhouse effect is very important to maintain life on Earth, so we will have to maintain the balance of greenhouse gas emissions for balancing it.
