Global warming and the change of climate on earth |
Posted: February 15, 2020 |
The topic of global warming and climate change is gradually becoming a matter of discussion among educated society environmentalists, scientists media workers and certain public representatives. In the discussions of this subject, in view of the possibilities of climate change, a church has also started to have a possible impact on human civilization and all living beings. Environmentalists and certain scientists predict that if the concrete steps are not taken in time, the lives of many animals will be affected and the lives of some animals will disappear. Increasing the amount of greenhouse gases in the atmosphere is considered to be the cause of global warming and change of seasons. The main greenhouse gases of the atmosphere are water vapor, carbon dioxide, methane, nitrous oxide and ozone. Due to the absorption of some amount of radiation from the sun by these gases from the sun, the temperature of the earth's atmosphere increases. This temperature increase is called the effect of green house gases. Observations suggest that the amount of carbon dioxide in the atmosphere is continuously increasing. Increasing the temperature of the atmosphere by one degree centigrade results in more than 7 percent evaporation. According to the 'Intergovernmental Panel on Climate Change (IPCC)', the effects of greenhouse gases are making ocean water slowly acidic and increasing seasonal accidents. Due to the changes in lifestyle and industrialization, the use of coal and petroleum products is increasing. Burning them increases the amount of carbon dioxide gas in the atmosphere. Similarly, methane gas is released into the atmosphere due to gases produced in the stomach of animals due to rotting in the atmosphere without oxygen in the soil of rice fields. Methane and other gases are generated due to hard coal mining, exploration and transportation of natural gas, sewage disposal plants and underground disposal of urban wastes. The contribution of methane from other water structures including the sea is notable. This contribution is notable for the organic overflowing with floods. This contribution is due to the organic matter flowing with the floods and the vegetation produced in the water structures to rot in the oxygen-free environment of its bottom. Climate change will have an impact on the world economy. It is estimated that due to climate change the world economy will decrease by about 20 percent. Apart from this, due to change in sea level, there will be displacement of about 10 crore people. Drought areas will increase five-fold and millions of people will become refugees due to drought. Every sixth person will suffer from water problems. There will be a serious threat to the life of wild animals and it is estimated that about 40 percent of the species will be lost from the earth forever. Lastly, all previous climate changes were controlled by astronomical forces. Industrialization and human intervention have been added to the current climate change. This is the basic difference between the past and present era of climate change, due to which, what would have been the end result of climate change, it is difficult to say but it is certain that only lucky species will rule the earth.
