Climate change is the most important issue at present in the world. It refers to the rise in average surface temperatures on Earth. The cause of climate change can be divided into two categories. They are due to natural causes and the causes created by men. The primary cause of climate change is the burning of fossil fuels, such as oil and coal, which emit greenhouse gases into the atmosphere—primarily carbon dioxide. Global warming is the main natural reason and using harmful chemicals in everyday life is the main reason created by man. Other human activities, such as agriculture and deforestation, also contribute to the proliferation of greenhouse gases that cause climate change. Tree plantation can reduce global warming which is the main natural reason for climate change.
The climate is changing rapidly that result in the rise of the earth’s average temperature. The developed nations, which are more responsible for such climate changes, should take responsibility to protect the victimized countries. The global climate change and its consequences are leaving, a bad impact on the developing countries like Bangladesh. The Maldives is also one of the worst victims of climate change. The serious consequences of climate change are, rising of temperature, greenhouse effect, erratic rainfall, floods, cyclones, drought, melting of polar ice-caps, etc. which seriously affect the livings of the people of poorer countries. Bangladesh, for its geographical locations, is likely to be the most affected. If everybody as one take a stand and try to end most of the climate changes that are occurring, this world would be a safer place to live on. The developed nations which are more, responsible for such climate changes, should take responsibility to protect the victimized countries. Climate change involves not only rising temperatures, but also extreme weather events, rising sea levels, shifting wildlife populations and habitats, and a range of other impacts. A one-meter rising of sea-level will submerge about one-third of the total ‘area of Bangladesh, which will uproot 25-30 million people of Bangladesh. Climate change is having economic and socio-political effects, too.
To reduce the bad impact of climate change people should be aware of it. Tree plantation can reduce global warming. Mass awareness about the environment and contribution of the international community in reducing greenhouse gas emissions can lessen the devastating change of climate. Avoiding the use of harmful chemicals can reduce environmental pollution. To materialize all these, Bangladesh has to work with the world community. Our warming climate is also creating a feedback loop as greenhouse gasses trapped in Arctic permafrost are released.
