Global warming is causing climate change. There is also prediction of regional climate changes along the ecosystem. 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. 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. 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. 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.

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.

This essay on global warming needs to look at the causes of the problem. Global warming is caused by an acute heating of the earth’s atmosphere as a result of energy being trapped. Greenhouse gasses such as carbon dioxide and methane can cause the atmosphere to build up, leading to solar radiation becoming trapped within the earth like within a greenhouse, hence the name. Global warming is the warming near the earth's surface that results when the earth's atmosphere traps the sun's heat. The earth is getting warmer. The changes are small, so far, but they are expected to grow and speed up. Within the next fifty to one hundred years, the earth may be hotter than it 3/5(7).

Global warming also changes the weather patterns. Many areas of the earth are experiencing severe weather conditions, drought, floods, and other uncommon weather conditions. Order global warming essay. Carbon dioxide (C02) is a major constituent of the environment. It is causing a warming effect on the earth’s surface area. Global Warming Essay 5 ( words) Global warming is the continuous rise in warming of the earth’s surface due to the increased level of carbon dioxide gas in the environment. Global warming has become a big issue which need to be solved by the positive initiation of countries all over the world.
