One major consequence of global warming arising out of greenhouse effect is the rise in sea level. Four major changes take place prior to this. Thus, the coastal cities and ports may be submerged under sea-water. Many islands may vanish from the earth surface as well as from the world map. Although changes in sea-level have received much publicity, problems of water availability are likely to be more serious and perhaps more expensive to solve.
In future, warmer world will face water crisis in some parts while in other regions it will be wetter than it is now. There is uncertainty regarding regional forecasts of future precipitation as warming of globe makes it difficult to predict.
Also, pattern of agricultural changes, or effects on ecosystems in general are fairly unpredictable. This also puts threat on the rich biodiversity of the ecosystem. The human health is put at risk because of Global warming.
In recent years, there have been newer reports of spread of major tropical diseases with changing climate. As the earth becomes warmer, more and more people are likely to be affected by tropical diseases. The problem of Global Warming can be controlled by minimizing the emission of greenhouse gases into the environment.
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. If the imbalance continues to rise, one day this will pose a question mark on the existence of this planet. It increases the evaporation of water into the atmosphere.
Since water vapour itself is a greenhouse gas, this causes still more warming. The warming causes more water vapour to be evaporated. The C02 level is expected to rise in future due to ongoing burning of fossil fuels and landuse change. The rate of rise will depend largely on uncertain economic, sociological, technological and natural developments. Other gases such as methane, CFCs, nitrous oxide, tropospheric 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 urbanisation, 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 cent of all carbon emissions entering the atmosphere, by the burning and cutting of 34 million acres of trees each year.
Everyday over acres of rainforest are destroyed. As a consequence of massive loss of forests, global CO, levels rise approximately 0. 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. 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 risen from 0. 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 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. 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.
Global warming is also largely a result of the release of methane from cracks in the earth, landfill sites and through natural gas leaks. Methane has an effect on the atmosphere which is four times as bad for global warming as carbon dioxide.
Global warming is the increase in the surface and atmospheric temperature generally caused by presence of excess amount of greenhouse gases (such as carbon-di-oxide (CO2), Chlorofluorocarbons (CFCs), etc.) and other pollutants resulting in a change in climate, greenhouse effect, and other negative consequences on the environment.
Keywords: global warming essay, causes of global warming, global warming solution. Introduction. What is global warming? Global warming is the average temperature of Earth has increases since until now the temperature continuing increasing. Global warming can also refers to climate change that causes an increase in the average of temperature. Effects of Global Warming Essay Words | 6 Pages initiated a warming sequence as a result of human produced greenhouse gas, carbon dioxide, and methane that may lead to catastrophic weather conditions, the disappearance of Pacific islands, and a new ice age.
Essay Global Warming and Its Effects - Global warming is an increase in the earth's temperature due to fossil fuels, industry, and agricultural processes caused by human, natural, and other gas emissions. This results in an increased emission of greenhouse gases. An Interesting Global Warming Essay Example for College Students. Writing an academic paper on global warming and its effects is not a difficult task if you have a good example to follow. If you continue reading, you will find an essay on global warming that you can use as an example for your next school project. You can use this example at no cost.
