The customized airtight glass buildings that are majorly used to grow plants in inhabitable cold weather are termed as greenhouses. These constructions are majorly used by the botanists and the traders.
The major working principle behind the greenhouses is the scientific theory that the heat absorbed from the sunlight is emitted by the earth’s surface as thermal radiation, which is further absorbed by the greenhouse gases present in the atmosphere. The heat absorbed by greenhouse gases is circulated in every direction. The major gases which come under the category of greenhouse gases are ozone, water vapor, methane, and carbon dioxide. Likewise, the roof of the greenhouses is created with translucent substance, which though allows the entrance of the sunlight, would not allow the absorbed heat to escape from the building. It is seen in this disadvantages and advantages of greenhouse effect article that it is the infrared energy with a higher wavelength that heats the walls of the greenhouses. The houses in the nations with cold climate use this technology which has proven to save up to 35 % of the domestic electricity bill.
The gases present in the atmosphere of the earth are not capable of absorbing the heat directly from the sunlight. It is why the earth gets heated first because of solar radiation. As mentioned in the above section of this article on disadvantages and advantages of greenhouse effect, it is the resultant radiation coming out of the earth’s surface that heat up the greenhouse gases. The whole process is altogether termed as the greenhouse effect. Until there was human intervention or exploitation of the ecosystem, there was an appropriate balance between the heat absorbed by earth and radiation expelled into the space. The increase in carbon dioxide because of activities like deforestation, inconsiderate combustion of fossil fuels, etc. has considerably increased the impact of the greenhouse effect.
Below are listed down the disadvantages and advantages of greenhouse effect.
– Makes it possible to cultivate seasonal crops even in an inhabitable environment.
– Helps in sustaining appropriate temperature on earth by acting as a filter towards escaping thermal radiation to space.
– It is the greenhouse effect that sustains the livable environment on earth. In its absence, the earth would have been hostile for life.
– Leading towards abrupt climatic alterations that have led to unforeseen natural disasters. It is the effect of global warming that frequent droughts and hurricanes are striking various parts of the earth.
– The increase in fossil fuel combustion has increased the level of carbon dioxide in the environment. The resultant increase in global temperature has led to the decline of many species.
– The increased level of carbon dioxide in the environment is slowing down the pace of photosynthesis in animals. It is further adding up to the accumulation of carbon dioxide in the environment.
As mentioned above in this article of the Disadvantages and advantages of greenhouse effects, the major greenhouse gases are: –
Though the high rate if human intervention in the ecosystem has introduced more potential greenhouse effects in the atmosphere. They are: –
Now let us move on to the detailed discussion over the disadvantages and advantages of greenhouse effect.
Though the greenhouse effect is considered as the major villain in the global scenario because of its considerable role in hiking global warming, the phenomenon itself is the exclusive factor that sustains life on our planet. Hence there are some evident advantages of greenhouse effect. The appropriate temperature to sustain life on earth is made possible by the phenomenon of the greenhouse effect. If there was no filter for escaping terrestrial heat radiations, the earth would have been a cold and barren planet.
It is by the dint of the greenhouse effects that the water level of the planet is sustained at a particular level. It is by the appropriate regulation by the greenhouse effect that the ice at the poles still remains intact with the same volume. The melting down of the polar ice would considerably increase the sea level and even destroy the whole terrestrial life forms.
One of the most crucial greenhouse gases is ozone which prevents the entry of harmful Ultraviolet rays to the surface of the earth. The exposure to the ultraviolet rays would result in the extinction of the majority of life forms from the earth.
Various harmful radiations fail to reach the surface of the earth because of the presence of various greenhouse gases. The layer of greenhouse gases in fact acts as the filter to avoid any entry of the harmful radiation to the surface of the earth.
These are some of the major advantages of greenhouse effects on earth. It is the prolonged effect of greenhouse effects through millennia that has transformed the earth into an inhabitable land. The greenhouse effect act as a balancing agent between the incoming energy and reflected energy.
The evident impact of the greenhouse effect on global warming is now an undeniable fact. The increasing greenhouse effect is creating a lot of menacing effects all around the world. The major negative effect of the greenhouse effect is the rising sea level which would risk the lives of millions of people living in islands and seashore. The increased rate of melting in polar ice because of the fluctuating global climate has contributed a lot to the increasing seal level. It has also been observed by the scientists that the increased level of carbon dioxide is sabotaging the marine biomes along with disrupting the rate of photosynthesis among vegetation. Though we have discussed numerous advantages of greenhouse effect in the previous section of this article named as disadvantages and advantages of greenhouse effect, let us have a look at some of its evident disadvantages: –
The above-mentioned disadvantages reveal the significance of taking the issue of the greenhouse effect as a serious matter among the global community.
Major initiatives were taken to address the impact of global warming
The menace caused by the greenhouse effect on the global level has grabbed the attention of environmentalists and major steps have been taken by global organizations to counter it. The interventions made by the UN international bodies like IPCC- Intergovernmental Panel on Climate Change in the year of 1990 and 1992 is highly commendable in the field of environment conservation. It is by the efforts of IPCC that led to the establishment of the United Nations Framework Convention on Climate Change (UNFCC). The decision to establish the UNFC body was made at the United Nations Conference in Environment and Development (UNCED). The function was organized in the city of Rio de Janeiro, Brazil in 1992. The conference is also termed as Earth Summit.
Many interventions to be made were suggested at this conference. They are: –
In this agreement, various countries ensured the imminent need of checking the emission of greenhouse gases. The Paris agreement is considered to be a milestone towards the efforts to save the environment of the earth by sustaining its natural environment. The agreement was signed around by 175 countries, who were curious about the future of the global environment.
