In today's era, man has been developing many new technologies day by day. Man is playing with nature in many ways for development, due to which it is becoming very difficult to maintain the balance of nature. Due to all this the earth is facing many problems. Out of which global warming is a very serious problem.
Global warming is a big problem not only for our country but for the whole world. Our earth is getting warmer day by day by continuously receiving sunlight, due to which the level of carbon dioxide in the atmosphere is increasing. This problem is harming not only humans, but every living being on the earth.
And to deal with this problem, every country is constantly taking some measures, but instead of decreasing global warming, it is increasing continuously. To deal with this problem, people should know its meaning, cause and effect so that its solution can be reached as soon as possible.
To combat this, we all should come forward together and solve it to save life on earth.
Global warming is the continuous increase in the temperature of the earth's atmosphere.
In other words - when the amount of carbon-dioxide in the atmosphere increases, the temperature of the atmosphere increases. This change in temperature is called global warming.
Meaning of global warming or global warming
Global means 'earth' and warming means 'hot'. Global warming (or global warming) refers to the increase and expected continuation of the average temperature of the Earth's near-surface air and ocean since the 20th century.
To understand in simple words, global warming means 'increased temperature of the earth and due to this changes in the weather'. This increase in Earth's temperature (which has been estimated at 10 Fahrenheit over a 100-year average temperature) results in changes in rainfall patterns, melting of icebergs and glaciers, rising sea levels, and impacts on flora and fauna. effects may come to the fore.
Due to global warmingÂ
Green house gas
Greenhouse gases are the most responsible for climate change caused by global warming. Greenhouse gases are those gases which absorb the heat from the sun. The most important of the greenhouse gases is carbon dioxide, which we living beings emit with our breath. According to environmental scientists, the amount of carbon dioxide in the Earth's atmosphere is increasing. Other greenhouse gases are nitrogen oxides, CFCs, chlorine and bromine compounds, etc. All these mix together in the atmosphere and disturb the radioactive balance of the atmosphere. They have the ability to absorb hot radiation, which causes the Earth's surface to heat up.
Pollution
Pollution is also one of the reasons for the continuous increase in the temperature of the atmosphere. There are many types of pollution – air pollution, water pollution, land pollution, noise pollution etc. Due to pollution, many types of gases are being formed in the atmosphere. These gases are the main reason for the rise in temperature and pollution helps in the formation of these gases.
Population Growth
Population growth also contributes significantly to increasing the temperature of the atmosphere because according to a report, 90 percent of global warming is contributed by anthropogenic carbon emissions.
Industrialization
Promoting urbanization, factories and companies are continuously increasing in urban areas. From which toxic substances, plastics, chemicals, smoke etc. come out. All these substances perform the function of heating the atmosphere very well.
Deforestation
Man keeps tampering with nature for his convenience. Man has made the atmosphere very hot by cutting down the trees and plants that keep the earth's atmosphere balanced, due to which the sea level is rising, due to such rise in the water level of the sea, many parts of the world are in water. There will be huge destruction, be it a world war or an "asteroid" from the earthThe devastation caused by a collision would be even worse.This will prove to be very harmful for our earth.
Depletion of ozone layer
Depletion of the ozone layer in Antarctica is also one of the reasons for global warming. The ozone layer is decreasing due to the increase of CFC gas. This is a man-made cause of global warming. cFC gas is used in many places as aerosol propellant in industrial cleaning liquids and in refrigerators, whose regular increase leads to depletion of the ozone layer.
The job of the ozone layer is to protect the earth from harmful rays. Whereas, increasing global warming of the Earth's surface is a sign that the ozone layer is depleting. Harmful ultraviolet rays of the sun enter the biosphere and are absorbed by greenhouse gases, which ultimately increases global warming.
Fertilizers and Pesticides
Fertilizers and pesticides used to protect crops from insects in the fields are harmful to the environment. They not only pollute the soil but also release gases like carbon dioxide, methane and nitrous oxide into the environment which are responsible for global warming.
Effects of global warming
(i) Due to the means of increasing global warming, its effect has become very clear in some years. According to the US Geological Survey, there used to be 150 glaciers in Montana Glacier National Park, but now only 25 remain because of its impact.
(ii) Hurricanes are becoming more dangerous and powerful due to major climate change. Natural storms are becoming more powerful by taking energy from temperature differences. The year 2012 has been recorded as the warmest year since 1895 and the year 2003 along with 2013 was recorded as the warmest year since 1880.
(iii) Many climate changes have taken place due to global warming such as increase in summer season, decrease in cold season, increase in temperature, change in wind-circulation, jet stream, off-season rains, snow peaks Melting, ozone layer depletion, severe storms, cyclones, floods, droughts etc.
(iv) If global warming continues to increase in this way, then all the icy places will melt and lose their existence. Nowadays the heat is increasing more and in winter the cold is getting less. When we look at the survey, we come to know that the temperature of the earth is increasing gradually.
(v) Cancer-like disease can occur due to the increase of carbon-dioxide gas.
(vi) Along with the expansion of the desert due to global warming, many species of animals and birds are also becoming extinct.
(vii) Due to the increase in global warming, the amount of oxygen is also decreasing, due to which the ozone layer is getting weaker.
Global warming is a process developed by humans because no change happens automatically without touching anything. If global warming is not stopped, then we will get to see its terrible form ahead, in which the earth may not exist, so we humans should think about it together with harmony, intelligence and unity, or it is necessary to find a solution,
Because the oxygen with which our breath moves, due to these dangerous gases, the same breath does not stop. Therefore good natural improvement is necessary more than technical and economic comfort. To reduce global warming, as many efforts as possible should be done.
People should be encouraged to plant trees, so that the amount of carbon-dioxide can be reduced and pollution can be reduced.
