Greenhouse Gases and Climate Change


I am a content writer , writing is my passions. My aim is to reach the world through articles and identify myself as a good writer.

Green House Effect Process


Green House Gases and Their Effects on Earth

Greenhouse gases are naturally present in the atmosphere and are also essential for life on earth. But, unfortunately due to industrial revolution there has been a huge increase in the emission of greenhouse gases in the atmosphere. Global warming has been seen to increase manifold by human activities. Due to which it has made its major contribution in increasing problems like climate change and global warming.

The effect of greenhouse is very important in the absorption of heat and makes the temperature of the earth warm and life-friendly. The biggest problem of the greenhouse effect is that it is increasing rapidly and the problem of climate change is arising due to the large amount of greenhouse gases emitted.

While greenhouse gases are also produced naturally, it is also produced by human activities and the balance of man-made greenhouse gases has been deteriorating from day to day. Due to which many serious problems are arising.

1.Carbon Dioxide (CO₂)

Carbon dioxide is the most important of all greenhouse gases and its main sources in the atmosphere are clearing of the land, burning fossil fuels and cement production and many other natural sources such as volcanoes, the use of oxygen for the respiration of organisms, the decay of organic matter and Combustion etc. Photosynthesis is done by natural objects that absorb carbon dioxide from the atmosphere, which is very important. Carbon dioxide found in oceans is also absorbed by marine organisms. But deforestation and the large number of trees being cut and new trees not being planted are also adversely affecting the environment.

2. Water vapor (H₂O)

Water vapor is one of the most powerful greenhouse gases in our planet's atmosphere. Evaporation of water present on the surface of the Earth has increased rapidly due to the warming climate of the Earth. The faster evaporation occurs, the faster the concentration of greenhouse gases increases.

3. Methane (CH₄)

A very small amount of methane is present in the Earth's atmosphere. Methane also stays in the atmosphere for a shorter period than carbon dioxide. Sources of methane include volcanoes, wetlands, seepage vents, methane oxidizing bacteria, livestock, burning of natural gases and coal, decomposition in landfillos, combustion of biomass, etc. This gas is mainly present in the soil and atmosphere.

4. Nitrous oxide (N₂O) and fluorinated gases

Greenhouse gases produced due to industrial activities include fluorinated gases and nitrous oxide. Of these, the three main gases are hydrofluorocarbons (HFCꜱ), sulfur hex fluorocarbons (SF₆) and perfurocarbons (PFCꜱ). Fluorinated gases do not occur naturally; they are man-made. It is mostly produced by human activities such as industrial work. Bacteria present in soil, stool urine management of animals and use of fertilizers in agriculture are its main sources.

5. Ozone (O₃)

Terrestrial ozone is one of the most important greenhouse gases in the atmosphere. It arises mainly due to air pollution and has a very different contribution to the balance of the earth's radiation. Ozone is present on both the upper and lower atmospheric surfaces of the Earth. Ozone is a very harmful air pollutant in the atmosphere, it is produced when particles emanating from vehicles, power plants, chemical plants, industrial boilers, refineries and other sources react chemically with the sun's radiation. .

Reasons for increasing greenhouse effect

Natural reason:

  • Due to some elements naturally present on the earth, such as carbon dioxide, which is 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 Green house gases are manufactured. Only fluorinated gases are produced by humans, which are not naturally present in nature.
  • Water vapor also has a very important contribution to the greenhouse effect.
  • Thermal energy is absorbed by water vapor, mostly when the air is increased in volatility. Due to this, the temperature in the atmosphere also increases.Animals take oxygen from the atmosphere

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, polluting the atmosphere. Apart from this, digging of gas and coal mines and oil wells also emits methane gas.
  • Deforestation is another major cause for the greenhouse effect. Plants also play an important role in reducing the amount of carbon dioxide in the environment and providing oxygen.
  • Unnaturally made nitrogen which is used as fertilizer in crops. Which emits nitrogen oxides in the atmosphere, thereby increasing the greenhouse effect.
  • Industrial gases are emitted in huge quantities throughout the world. Gases like methane, carbon dioxide and fluorine gas fall under 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 (CO₂), water vapor (H₂O), methane (CH₄), ozone (O₃), nitrous oxide (N₂O) etc. are gases that enhance the greenhouse effect.
  • Greenhouse gases have the largest amount of CO₂ 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 burnt a large amount of fossil fuels and our atmosphere has been polluted with poisonous gases due to massive tree harvesting, large quantities of 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.

The more greenhouse gases are emitted, the greater their concentration in the atmosphere. Each of these gases is present in the Earth's atmosphere for different times, such as from a few years to a few thousand years.

The effect of each of these is different and is more effective than some others and heats the temperature of the Earth more.

Along with this, many aspects of the environment have changed due to climate change such as hot climate, rising sea level, drought etc. Which will affect the temperature of the earth for centuries and with this we should also be prepared for the adverse effects of climate change in the future. I

If we still ignore the extent of its damage, then its consequences can be more serious in the future. We need to make efforts to prevent this already and for this we need to encourage more and more use of renewable energy resources.

because people aren't understanding it they are also paying off.

A very good work from your side, do more articles.

Ms Sharma (author) from India on July 18, 2020:

Thanks to read the article......

I think it is a great need in today's world that people understand the value of environment.

Devatva Tripathi from LUCKNOW on July 13, 2020:

It was explained in a very easy and understanding way.

these are real topics to be talked about.

very impressive
