Climate Change of Bangladesh as a result of Global Warming

Gradually the climate of Bangladesh is changing because of global warming. This is the most alarming news not only for Bangladesh but also for our planate. Let’s know about the climate change of Bangladesh as a result of global warming.

What is global warming?

One of the biggest environmental challenges that affect not only Bangladesh but also the whole world is the phenomenon of Climatic change. Worldwide it has been observed that the temperature has been slowly increasing in the 20th century. This phenomenon is called global warming.

Cause of global warming

The main reason for global warming is the increase in the level of carbon dioxide in the atmosphere, chiefly due to the burning of fossil fuels.

The sun’s rays pass through the earth’s atmosphere and strike the surface, warming up our planet and making it possible for life to exist. Some of the incoming rays are reflected back into the atmosphere, while others are absorbed on the surface.

The reflected waves cannot pass back into space; thus these waves are trapped within the earth’s atmosphere. The energy of these waves helps to heat up the earth more than if the atmosphere was not there. This is called the greenhouse effect, as a greenhouse is kept warmer than the surroundings by a similar method.

Some constituents of the atmosphere are more efficient at trapping heat, and such gasses are called greenhouse gasses, carbon dioxide being an important member of this group. The increase in the level of carbon dioxide in recent years has increased the trapping of the reflected heat, thus leading to global warming.

Effects of global warming on climate change of Bangladesh

It is thought that the effect of the increased temperature will be destructive to many areas of the world. In low-latitude areas, the change will be minimal about 0.05 to 0.25 degrees C. However, at higher latitudes, the changes will be more drastic, as much as 5-9 degrees C.

According to current predictions, this temperature rise will cause the polar and Himalayan ice caps to melt leading to a rise in the earth’s sea level of at least 2 to 3 meters by the year 2050. This will undoubtedly cause all the low-lying delta regions of the world to be submerged, and that is bad news for Bangladesh. A huge percentage of the southern part of the country is at risk of being submerged by the Bay of Bengal.

It has been found that an increase in the temperature of the sea aids in the formation of cyclones, which may have disastrous effects if they hit the country.

Increased water levels can lead to floods in the country that, in turn, increase the risk of inundation. In tropical countries like Bangladesh, this comes with diseases like malaria and cholera.
