What are Greenhouse Gases (GHGs)?

What are Greenhouse Gases (GHGs)?

Greenhouse Gases (GHGs) are considered an important topic, attracting the attention of many people at the present time, as the world has become aware of the impact of these gases on the environment and its resources. These gases are one of the causes ofglobal warmingin the atmosphere surrounding the Earth on the one hand, and on the other hand their loss may cause the average temperature of the Earth’s surface to be about (-18) degrees Celsius, instead of the current average of (15) degrees Celsius.

Therefore, there is a relationship between increasing levels of Greenhouse Gases (GHGs) and increasing rates of global warming. Despite its importance in maintaining the Earth’s warmth – this is the secret of calling it a greenhouse – in recent years, it has gained a bad reputation after becoming a major cause ofglobal warming; These Greenhouse Gases (GHGs) are, quite rightly, Greenhouse Gases (GHGs). To learn more about the meaning of global warming, you can read the previous article “What is global warming?” from the series (What…?).

More clearly, the use offossil fuels – oil, coal, natural gas – causes the emission of carbon dioxide, in addition to farm animals that release large amounts ofmethane, and some other agricultural activities such as plowing fields, shipping crops to markets, and other practices that cause an increase in greenhouse gas emissions; Therefore, efforts to reduce these emissions and adapt to their impacts are an important path to preserving the health of the planet, and securing a sustainable future for us and for future generations.

Now, we will mention to you the most important types of Greenhouse Gases (GHGs), which are:

• Carbon dioxide:Carbon dioxide is considered one of the most important Greenhouse Gases (GHGs), as it contributes to about three-quarters of the emissions of these gases. Because it remains widespread in theatmospherefor thousands of years after negative activities such as: burning organic materials such as coal, oil, gas, and wood, as well as solid waste, cause its rates to increase. In this context, carbon dioxide levels in 2018 reached411 parts per million in the atmosphere above the city of Hawaii, the highest level ever recorded.
• Methane:Methane is the main component of natural gas, and is released from landfills,and petroleum industries, in addition to emissions produced by the digestive system of livestock.
• Nitrous oxide:Nitrous oxide makes up a small percentage of Greenhouse Gases (GHGs), but it is 264 times more potent than carbon dioxide. One of the mosthuman activitiesthat has caused its increase is the use of agricultural fertilizers.
• Water vapor:Water vapor is one of the most important Greenhouse Gases (GHGs). Despite this, it is not a direct cause of climate change. Therefore, changes in water vapor levels in the atmosphere are due to changes in surface temperatures and changes in climate patterns.

Effect ofGreenhouse Gases (GHGs) on climate

Greenhouse gas levels in the atmosphere – as we said previously – are rising as a result of human activities, which leads to an increase in the phenomenon of global warming, as we find thatClimate heatingleads to severe climate changes in the weather system worldwide, including an increase in surface temperatures, a rise in average sea levels, and changes in rainfall patterns, and then ecosystems and wildlife are affected. All of them.

The impact of Greenhouse Gases (GHGs) on the climate and environment is a global challenge, and it is a challenge that requires urgent action. To reduce emissions of these gases, by improving energy efficiency and encouraging the use of renewable energy sources. Accordingly,global efforts aim to achieve a balance in the rate of greenhouse gas emissions and reduce their environmental impact. In order to maintain the health and sustainability of planet Earth.

How can we reduce greenhouse gas emissions?

In this section of the article, we will present to you innovative solutions to reduce greenhouse gas emissions, which are:

• Reducing electricity consumption

Electricity production processes depend on burning coal or gas, which leads to the emission of large amounts of Greenhouse Gases (GHGs). Electricity consumption can be reduced through:

• Replacing traditional lamps with LED lamps.

• Adjust air conditioners to low levels in the winter and high levels in the summer.

• Installation of heat reflective glass.

• Amendment of farming methods:

Crop cultivation usually produces these harmful emissions to the environment, especially rice and corn crops, in addition to livestock raising. In theUnited States, for example, the agricultural sector contributes 9% of greenhouse emissions. But, how can we confront this? This can be addressed through:

• Reducing the use of heavy chemicals and petroleum fertilizers in agricultural operations.

• Reducing human nutrition on livestock.

• Using aerobic containment of fertilizer, as a way to reduce greenhouse gas emissions.

• Reliance onRenewable energy:

Coal-fired electricity production stationsare one of the largest sources of emissions, and this problem can be solved by relying on renewable energy sources, such as:

• Solar energy.

• Hydropower.

• Geothermal energy.

• Wind energy.

By following these solutions, we can reduce greenhouse gas emissions and reduce their impact on the environment and climate. That is why we must work to adopt sustainable lifestyles, and contribute topreserving our environment, for our sake and for the sake of future generations.

At the conclusion of this article, the magazineEarth Guardsemphasizes the importance of defining the term “Greenhouse Gases (GHGs)”, and it is an article from the series (What…?), which bringsenvironmental and development termscloser to people’s minds; So that we can achieve the Sustainable Development Goals (SDGs), and preserve and preserve the environment.
