Global Warming

One major human cause is pollution. People are creating more and more of it. One type of pollutant is greenhouse gases. These gases trap solar energy, increasing Earth’s temperature, rather than letting the heat back into space. Another cause is the burning of fossil fuels. Some fossil fuels are oil, gas, and coal. These produce carbon dioxide. We are producing too much of It Into our atmosphere too quickly and plants can’t absorb all of that carbon dioxide. We even cause global warming to be sped up by being alive. We exhale carbon doodle with every breath we take.

If we want to reduce global warming, to a state we can deal with and not worry about It, we need to start by reducing all of the pollution we create. Global warming may be a natural cause but “humans can be a powerful influence on the climate as well. ” It increases the evaporation of water into the atmosphere. Since water vapor itself is a greenhouse gas, this causes still more warming. The warming causes more water vapor to be evaporated. The CO 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 gallants 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 cent 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 CO. 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 CO Increases are due to man’s use of fossil fuels either In the form of coal, gas or 011. A large portion of carbon emulsion Is attributed to the burning of gasoline in internal-combustion engine of vehicles. Vehicles with poor gas mileage 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 port 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, as the sea rises, beach erosion takes place, particularly on steep banks. Wetlands are lost as the level rises. Rise in atmospheric temperature will lead 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 would be frequent. Consequently, malnutrition and starvation will pose serious challenge before humanity. Global warming is a great threat to the flora and 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. Argyle 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 1997 which came to be known as Kyoto Protocol. However, ten years have passed; the situation does not appear to be very changed. It seems that the member countries are not very serious about its devastating effects. In addition, forestation can be of great help in this regard. Imbalance. Secondly, we must follow on environmental policy of ‘reduce, reuse, recycle’, I. E. Promoting the reuse of anything.

Thirdly, the use of fuel-efficient vehicles should be promoted as these vehicles have lower emissions of harmful gases. Fourthly, every individual should be aware of the importance of the protecting environment. Besides, CEO- friendly technologies must be promoted, and must be substituted with the technologies which cause great emission of global warming gases. Public awareness campaign can be of great help in this regard because unless each and every individual is aware only governments’ effect cannot bring desired difference.
