What is the greenhouse effect and what are the main greenhouse gases?
A greenhouse effect is the heating phenomenon of the Earth and its environment due to sunlight incident radiation energy captured by greenhouse gases especially water vapors and carbon dioxide. This process occurs naturally, it happens whenever an incident striking shortwaves attains the gaseous layer surrounding the Earth, one portion is reflected back into space normally, and the other part is captured and emitted on the planet by greenhouse gases accumulated in the Earth’s troposphere. Consequently, this phenomenon keeps the globe warm and helps to maintain heat momentum. therefore, this natural process enhances Earth to support life smoothly and make it livable. Currently, the Greenhouse effect is being used as a special way of growing crops known as Greenhouse farming, it is mainly used in colder regions and in areas prone to climatic disasters, and also it is useful in places sunlight scarcity dominates, people use greenhouse gases to collect the sunlight, they help planted crops to attain the temperature which is required for the growth of the plant. Hence, these gases play the role of the greenhouse effect as they trap the radiation from the sun to support the growth of the plant, simply greenhouse effect is used in special greenhouse farming to grow special crops.
Advantages of the greenhouse effect
Without the greenhouse gases, all heat generated from the sun would have escaped from the Earth and it would have become cold and barren, it means no life would have been possible without the greenhouse effect, simply greenhouse effect is very important for the existence of life on Earth, and also to tackle the problem of food security in a region prone to climate disasters greenhouse farming system is a unique tool to do that.
The disadvantage of the greenhouse effect
As the surface temperature keep raising nowadays, from different sources such as burning fossil fuels, industrial emission, and automobiles exhaust, all those scenarios trigger Global warming, which is the increase of Earth’s average surface temperature due to the excess effect of greenhouse gases, when the surface temperature continues to raise it to lead to the rise of sea level which comes from glaciers and polar caps partially melt down, the areas surrounding the sea suffer a threat of flooding. The change in seasonal pattern is also influenced by the temperature which keeps raising, this change affects the natural habitat of wildlife, because the natural habitat of wildlife depends on the seasonal pattern, due to random and unexpected increases in the temperature, nowadays global warming is the threat to the existence of life on earth.
Greenhouse gases are mainly composed of carbon dioxide which contributes 40%, Methane with a 19% contribution, Chlorofluorocarbons (CFCs) which contributes 17%, Nitrous oxide contributes 12%, Ozone with an 8% contribution and water vapors with a 2% contribution of the greenhouse effect, the situation today on the matter of atmospheric pollution and warming of the Earth, the three major contributors got increased at remarkable extent since the 19th century at the start of industrial revolution accelerated by human activities. Carbon dioxide remains a crucial gas in developed countries and developing countries because it is a relevant source of energy and mainly depends on fossil fuels.
