Climate change means the changes in climate. Human activities are greatly responsible for climate change. For habitation and agricultural purpose, we are cutting down trees and destroying forests. This affects the climate adversely. Besides, use of CFCs and various other chemicals in industries causes serious harm to the ozone layer in the atmosphere.
As a result. there is a rapid increase in earth’s average temperature causing greenhouse effect. This is because, the world is greatly affected by climate change. Everyday one or another part of the world is now affected by natural calamities. Climate change has also serious impact on Bangladesh.
Because of climate change the glaciers are melting and the sea level is rising. Bangladesh may face different types of natural disasters such as floods, droughts. cyclone. Sidr. Ayla etc. Besides, some parts of the coastal areas of the country may go under water in near future.
So to solve this problem, the government of Bangladesh should take adequate precautionary measures to save life and property from the cruel claws of these natural calamities. Bangladesh has to work with the world community to save her people from the dangerous impacts of climate change.(150-200 words)
Changes in the earth’s weather including changes in temperature wind patterns and rainfall refer to as climate change. Climate change is a long term change in weather patterns over a long period of time. It’s now a major global concern. Greenhouse gases that include carbon dioxide, methane and CFC are tine main causes of this climate change.
Our atmosphere which is guarded by an ozone layer resists the entrance of ultra-violet rays from the sun causing greenhouse effect. Climate change is the worst of all the problems that affect all the flora and fauna of the environment.
Bangladesh, being a low-lying, land, may become the worst victim of it. There are many plants and animals that are vulnerable to climate change, The summer and rainy seasons are already prolonging and winter is shrinking. The river banks are being eroded and crop land is being reduced. Besides, saline water is Intruding into the rivers in the coastal areas resulting in damage to farm lands. Moreover, floods, droughts and other disasters hit the country more frequently nowadays.
Over the past century, sea level has risen by 10 to 20 centimetres as a result of global warming. The Sundarbans, world’s largest mangrove forest is also at severe risk. All these lead to more landless people and climate refugees in the country.(150-200 words)
Your paragraph should include the answer to the following questions:
- What does climate change mean?
- What are the causes of climate change?
- What are the effects of climate change?
- Why is Bangladesh vulnerable to climate change?
- What is the world’s largest mangrove forest?
- Why is it at risk now?
Climate Change in Bangladesh
We take various elements from nature for our use. We also behave rudely with nature. It has destroyed the balance of nature. The elements of nature are limited: most of the one we target it. However, unplanned urbanization and industrialization have affected the world environment, enormously. The enormous pollution of the environment is the most significant cause of the change of the world climate. Bangladesh is also under the threat of it.
The climate is changing mostly because of the greenhouse effect. The balance of the environment is breaking down for increasing the average temperature owing to the greenhouse effect.
According to the observation of the IPCC, the average temperature of Bangladesh has increased from 0.2 to degree celsius. Bangladesh is under the great threat because it is in the Asian region.
The probable posing threats to Bangladesh for global warming include:
Flood, cyclone, high tide, etc. which will be increased due to the change of the climate. It is damage our assets and lives massively specially in our coastal areas.
According to the opinion of the IPCC, the sea level of the Bay of Bengal will be increased about one metre by this century.
Rainfall will increase abruptly wit in the rainy areas for the change of the climate. So the global warming is increasing the threat for our coastal areas and low lands.
On the one hand, global warming will increase the rainfall in the rainy areas and on the other hand, it will stop the rainfall in the dry areas. So the desertification will happen in some areas of our country for the change of the climate.
The average temperature of Bangladesh will be increased up to 2 degree celsius by the year 10 2050. It will diminish the production of rice upto 10 and wheat upto 30% due to the shortage of the water for irrigation.
The temperature and the salinity of the sea water are increasing for the change of the climate. It will spoil the fishes of the sea and the mangrove trees and plants of the forest .
Bangladesh is under the great threat of the global warming. The change of climate is affecting the Asia greatly. Bangladesh, however, should take the following precautions facing the challenges of the climate change:
- To stop use of the CFC and the other greenhouse gases.
- To stop the use of firewoods and bio-fuels.
- To increase the public awareness about protecting the environment.
- To expand the programmes of planting trees all over the country, specially in the coastal areas.
- To monitor the behaviours of the world climate and taking decisions accordingly.
We should prepare effective and sustainable policies and strategies for facing the challenges of the climate change. It is our duty to remove the imbalance.(400-450 words)
