Scientists around the world are making great initiatives to combat the adverse consequences of the greenhouse effect. However, many of us are still aren’t much aware of it in detail which has emerged as the biggest threat to existence of life on planet Earth so far. Thus, if you are one of those who wants to know about this burning issue ‘what is greenhouse effect’, then here is what you need to know. The warming of Earth’s lowest layer of atmosphere (troposphere) and its surface because of trapping and absorption of the Sun’s radiation is known as the Greenhouse effect.
Causes of the Greenhouse Effect
Following here we would like to throw some light on the major factors responsible for it.
Typically, there are three significant factors that contribute to this burning environmental issue which includes:
● Chemical composition of the atmosphere which, relate to the greenhouse gases and their concentration levels.
● Total amount of energy influx of the sun which is related to the distance between the Earth and the Sun.
● Ability of our planet Earth’s surface to reflect light back to the space.
Now when we are aware of the major causes of the greenhouse effect, let us discuss about a step-by-step representation of formation of this natural phenomenon.
● Step 1 : Radiation from the Sun reaches the atmosphere of our planet Earth, some of which are being reflected back.
● Step 2 : Rest of the solar radiation is being absorbed by oceans and land of the Earth, which is gradually heating up our planet.
● Step 3 : Heat is being radiated from our planet to the space.
● Step 4 : A certain proportion of this heat is being trapped by the greenhouse gases present in the atmosphere which, help in keeping our planet enough warm to ensure life sustenance.
● Step 5 : Anthropogenic reasons like burning of fossil fuels, deforestation and agriculture are increasing the proportion of greenhouse gases in the atmosphere of our planet.
● Step 6 : This trapping of extra heat is rising the temperature of our planet further.
Human activities are certainly a reason behind the increased amount of greenhouse gases in the atmosphere since the onset of the Industrial Revolution. The amounts of carbon dioxide, nitrous oxide and methane have been increased rapidly over the past fifty years.
Anthropogenic Issues related to Global Warming
The greenhouse effect happens to be a natural-occurring phenomenon indeed. However, the harmful human activities, especially fossil fuel consumption in the transportation and energy sectors have multiplied the extremity of this natural effect by boosting the concentration of carbon dioxide, methane, nitrous oxide and other greenhouse gases in the atmosphere.
The most powerful weapon to fight against global warming is to enact aggressive policies and practices and follow them sincerely to reduce the concentration of greenhouse gases in the planet’s atmosphere. Though the Governments have imposed dozens of regulations related to carbon emissions, however, it is pivotal to make people aware of the dreadful environmental issue and bring that sense of caution to promote a sustainable living.
