These mills and factories produce black smoke which gets mixed with air and increases the amount of CA. Burning of Gas such as Methane (CHI) and fuel also increase CA in the environment. Killing animals like birds, big cats, lions, tigers is also a alarming cause of Global Warming. The effects of Global Warming is very dangerous for our existence and survival. The sun’s scorching heat comes to earth in a direct way. Therefore, the earth’s surface becomes seriously heated. Agriculture, forestry and fishery is seriously be damaged. This can catastrophically reduce mankind’s ability to grow foods, destroy wildlife.
Global Warming also cause sea-water to swell up. All species are important for maintaining ecological balance. If one is lost, the whole natural environment changes. To prevent the dangerous effects of Global Warming necessary steps should immediately be taken. It increases the evaporation of water into the atmosphere. Is once water vapor itself is a greenhouse gas, this causes still more warming. The warming causes more water vapor to be evaporated. The CA level is expected to rise in future due to ongoing burning of fossil fuels and landaus change.

The rate of rise will depend largely on uncertain economic, sociological, technological and natural developments. Other gases such as methane, Cuffs, nitrous oxide, troposphere ozone are also responsible for global warming. Increases in all these gases are due to explosive population growth, increased industrial expansion, technological advancement, deforestation and growing arbitration, etc. Trees play a significant role in the global carbon cycle. They are the largest land-based mechanism for removing carbon dioxide from the air. Deforestation is checking these positive processes.
It is the second principle cause of atmospheric carbon dioxide. Deforestation is responsible for 25 per .NET of all carbon emissions entering the atmosphere, by the burning and cutting of 34 million acres of trees each year. Everyday over 5500 acres of rainforest’s are destroyed. As a consequence of massive loss of forests, global CO, levels rise approximately 0. 4 per cent each year, the levels not experienced on this planet for millions of years. As we know the forests are the great absorbers of There is a close relation between global warming and population growth.
Today the large population on earth is using the technologies which are destructive for the earth. Approximately, 80 per cent of atmospheric CA increases are due to man’s use of fossil fuels either in the form of coal, gas or oil. A large portion of carbon emission is attributed to the burning of gasoline in internal-combustion engine of vehicles. Vehicles with poor gas mileage contribute the most to global warming. Besides, the sulfur group gas is the most harmful for this. Its contribution is 30 per cent in global warming. This gas is also emitted from the burning of fossil fuels.
Increase in global temperatures will cause rise in sea level. It will lead to melting of glaciers, changes in rainfall patterns, increased intensity and frequency of extreme weather. As per the latest survey report the rate of melting of glaciers has seen sharp increase in recent times. Even those glaciers are affected from global warming which have been considered permanent. The shrinking of glaciers is going to pose a major problem of drinking water. The sea levels as a result of melting of glaciers have risen from 0. 35 mm to 0. 4 mm.
Scientists have warned in their reports that most of the glaciers will disappear within a period of 15 to 25 years. It will create problems of drinking water and food grains in most of the North American countries. India is not unaffected from it. The Himalayan glaciers have shrunk about 30 per cent after 1970. The rise in sea levels is a major cause of concern. A large number of cities located in coastal areas will submerge in the sea. Besides, many island countries will ultimately “lose their existence and will be washed away from the surface of the earth.
The damage of rising sea levels is diverse. Buildings and roads close to the water could be flooded and they could suffer damage from hurricanes and tropical storms. Experts believe that global warming could increase the intensity of hurricanes by over 50 per cent. In addition, a: he sea rises, beach erosion takes place, particularly on steep banks. Wetlands are lost as the level rises. Rise in atmospheric temperature will lee to the outbreak of air”borne and water-borne diseases. It would also contribute to the rise in death caused by heat.
The problem of drought woo be frequent. Consequently, malnutrition and starvation will pose serious challenge before humanity. Global warming is a great threat to the flora an fauna of the earth. A large number of species of them may become extinct. The expanse of desert would increase. Low rainfall and rising temperature could add to the intensity and frequency of dusty storm. This in turn Will immensely affect the quality of agricultural land, ultimately causing adverse effect on agricultural produce. It would have far-reaching socio-economic impact.
In Indian context, the impact of global warming is a matter of grave concern As is well known, India is mainly an agricultural country and agriculture here is gamble of the monsoon, e. G. Largely depending on rainfall. Though it is to affect the whole country, the worst likely impact would be on central and northern India which is high-yielding parts of the country. These are the regions which produce the largest agricultural yield. The rise in atmospheric temperature and fall in rain would naturally result in decline in crop production.
Moreover, it would have great effect on biodiversity as well. The growing concerns over global temperatures have led to the nations, states, corporations and individuals to draw out a plan of action to avert the situation. As a result the world’s primary international agreement on combating global warming was reached in Kyoto in 1 997 which came to be known as Kyoto protocol. However, ten years have passed; the situation doll not appear to be very changed. It seems that the member countries are not ere serious about its devastating effects.
