Controversy over Global Warming One of the largest argued topics in our world today is over global warming. People argue that is real, and others argue that it is fake. The effects of global warming create a growing danger for the ecosystem we live in by damaging glaciers and weather patterns. Humans contribute to global warming yet nonbellevers will think otherwise. Global warming is the greatest challenge facing our planet. According to the IPCC (Intergovernmental Panel of Climate Change) most of the case for global warming is a process that occurs when rays from the sun pass through the atmosphere warming the surface of the planet.

In short, global warming represents a fundamental threat to all living things on earth. Global temperature has risen significantly during the past century. The scientific view is that most of the temperature increases since mid-20th century has been caused by increases in the greenhouse gas concentrations, which are produced by everyday human activity. Most scientists agree that f people stop burning fossil fuels the greenhouse gases already e mitted will warm the planet two degrees by the end of the century. “The fact is, we are not making a lot of progress in reducing emissions”, Richard Moss. nbc. ews) As a result, the world is getting increasingly warmer and warmer each year. The years of 1983, 1987, 1988 and 1989 have been measured to be the warmest six years in the last hundred years. The year 1991 was the second warmest year of the past century. (“Untitled Document. unfortunately, the imbalance which we have created between our life and earth is already showing the signs disasters in the form of flood, cyclones, landslides, tsunami, drought, etc. Glaciers have shrunk, ice on rivers and lakes are breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner.
In North America there is a decrease in snow pack in western mountains and an increase in heat waves in the cities that have them (climate. nasa). If this continues to rise one day this may even threaten the existence of planet Earth. Carbon dioxide,

also known as C02, is an important component of environment. This element is causing a warming effect on the earth’s surface. 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 C02 level is expected to rise in future due to ongoing urning of fossil fuels and land use change. 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 cent of all carbon emissions entering the atmosphere, by the burning and cutting of 34 million acres of trees each year. Every day over 5500 acres of rainforest are destroyed.
As a consequence of massive loss of forests, global CO, levels rise approximately 0. 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 1 OF3 Approximately, 80 per cent of atmospheric C02 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 sulphur 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 isen 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. (“Science News )lt 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 he 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. (“Hurricane Intensity. “) Wetlands are lost as the level rises. Rise in atmospheric temperature will lead to the outbreak of airborne 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- In Indian context, the impact of global warming is a matter of conomic impact. 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 emperatures 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 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. Planting more trees and reducing timber cuts worldwide will help restore the 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, eco- 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.See More on Carbon dioxide
