Global warming : INDIA

We keep reading about rising temperatures and sea-levels in other parts of the world like United States and the UK, but actually India is one of the most vulnerable countries when it comes to effects of global warming. India has a vast coastal line and the rising sea levels caused by global warming will cause an ecological disaster.

Bengal will suffer
The Himalayan glaciers have started to melt and the average rate of retreat is almost twice (34 metres) per year as compared to the 1971 levels of 19 metres. The melting glaciers will cause temperatures and sea-levels to rise and there will be a cascading effect on the crops and the monsoons. Worse - whole islands are expected to vanish! In fact two have already gone under - two islands in the Sunderbans, an area which India shares with Bangladesh. Temperatures in the group of islands has already gone up by one degree centigrade.

Rising sea-levels will be a disaster
While some climatologists say that sea levels will increase by just 4-35 inches from 1990 levels in another hundred years…some feel that the range could be higher - 20-55 inches. Thats a lot and will affect human habitat in a big way. In fact, as far back as 1993 a study to evaluate the impact of rising sea levels on India was carried out by JNU (Jawaharlal Nehru University). They calculated what would happen if the sea-levels rose by just 1 metre…and they found that as many as 7 million people would be displaced and 5,764 sq km of land and 4,200 km of roads would be lost!

Why is only the east coast of India being affected?
This is because the Bay of Bengal is landlocked from three sides and there is a huge delta of the rivers Brahmaputra and the Ganga. These rivers will carry the water from the melting Himalayan snows. However this does not mean that the western coastal regions are immune…just that the eastern coast is more vulnerable at this stage.

So what are these green house gases which are causing the snows to melt? According to the Wiki greenhouse gases are “include water vapor, carbon dioxide, methane, nitrous oxide, and ozonecomponents of the atmosphere that contribute to the greenhouse effect. Some greenhouse gases occur naturally in the atmosphere, while others result from human activities.
