Climate Change Effect On Earth

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 temperature is increasing day by day. This increase in global warming is 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.

What is the greenhouse effect? It is the gradual warming of the air surrounding the earth as a result of heat being trapped by environmental pollution. This is exemplified by the destruction and burning down of tropical rainforests, by traffic that clogs up city streets, by the rapid growth of the industry, the use of chlorofluorocarbons(CFCs) in packaging and manufacturing commercial products, the use of detergents such as washing powder and washing up liquid and so on. The oceans are also said to be affected both because of human waste and because of pollution caused by industrial waste products, oil seeping from damaged supertankers and from other maritime disasters. However, 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.
Climatologists predict that by midway through the next century temperature may have risen by as much as 4 ͦ C. 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 under water.
