Write a Paragraph on Climate Change

Climate change is now the most unpredictable (যার সম্বন্ধে আগে থেকে বলা যায় না) threat (হুমকি) to our planet. The earth’s climate has changed over the last century. There is stronger evidence (প্রমাণ) that most of the warming (উষ্ণায়ন) observed the last 50 years is due to human activities. Because of gas productions, temperatures should continue to rise over the 21st century. Its impact will be severely (গুরুতরভাবে) negative on both mankind and nature. Human activities that contribute (অবদান রাখে) to climate change include in particular the burning of fossil fuels (জীবাশ্ম জ্বালানী), agriculture and land-use changes like deforestation. These cause emissions (নির্গমন) of carbon dioxide. It is the main gas which is responsible for climate change. And for this possibly (সম্ভবত) many catastrophic (বিপর্যয়কর) changes will be inevitable (অনিবার্য). The more the greenhouse gases are emitted, the higher the tendency will be for the earth to warm. It will widespread the melting of snow and ice. Serious consequences (পরিণতি) will be a rise in sea levels, which will endanger coastal areas and small islands. Therefore, only reducing emissions of greenhouse gases should reduce the risk of the adverse effects .Many options for emission reduction (হ্রাস) is available. But the whole world needs to be concerned to remove this fatal (মারাত্মক) threat.
