Global warming Paragraph

(a) What is global warming?

(b) What do many alarming reports say?

(c) What do most climatologists believe?

(d) What is the alarming news about Bangladesh?

(e) How can Bio-ban warming be prevented?

In recent years, there have been many alarming reports that the world's climate is undergoing a significant change. All these reports provide strong evidence that world temperatures are increasing day by day. This increase is known as global warming caused by increased amounts of carbon dioxide around the earth.

Most climatologists believe that the greenhouse effect is the most likely cause of this global warming. Climatologists predict that by midway through the next century temperatures may have risen by as much as 4C. This could catastrophically reduce mankind's ability to grow food, destroy or severely damage wildlife and wilderness, raise sea levels and thereby flood coastal areas and farmland. The alarming news about Bangladesh is that as a result of the rise of the sea level the lower southern part of the country may one day go underwater. The main culprits for global warming are carbon dioxide gas, produced by the burning of fossil fuels and forests and pollutants such as methane and chlorofluorocarbons.

Trees can play a great role in preventing global warming. Therefore, more trees should be planted and the tree plantation programme should be extended throughout the country. Moreover, we should abstain from cutting any burning trees at random. After all, we can prevent global warming by being careful and raising public awareness.

Global warming or Green House Effect

The rise in atmospheric temperature causes global warming. The main culprit for global warming is carbon dioxide gases. This gas is being released into our atmosphere for various activities. The burning of fossil fuel is the main cause. Every day a huge quantity of carbon dioxide gas is emitted into the atmosphere from the engines, vehicles, mills, factories etc. Trees and plants absorb carbon gases. But they are also being cut down in large number. So carbon gases are being increased in the atmosphere. 

Consequently, our earth is getting hotter. The effect of this global warming is dangerous. The ice in the polar regions is melting and if the process continues for a long time the water level in the oceans will rise and thereby flood coastal areas and farmlands, which will go underwater. The alarming news about Bangladesh is that for the rise of the sea level, the lower southern part of the country may one day go underwater.

Climatologists predict that in the middle of the next century, temperatures may have risen, up to 4°C. This could reduce mankind's ability to grow food and severely damage wildlife. So random cutting down of trees must be stopped. The tree plantation programme must be made more popular. Sources of emitting carbon dioxide and carbon monoxide should be controlled.
