Climatic changes have become more prominent now because of the global warming which is a global concern. Both are hot issues of the current time and it is the time to analyse causes and prevention methods to prevent the global warming. The release of various green house gases in the atmosphere by many natural means and human activities causes increase in atmospheric temperature because such gases have capability to absorb all the heat of environment from sun, burning coal, etc. Such gases never let sun rays to go back to the atmosphere however trap heat from them.
Increase in atmospheric temperature causes many climate changes like increase in sea level, flood, drought, weather changes, increase summer season, decrease winter season, melting glaciers, increase death rate, increase number of disease, declining ozone layer and other so many climate changes. Fossil fuels burning release more carbon dioxide which is increasing day by day because of deforestation. Plants are the main source to utilize carbon dioxide as a food however we are disturbing the natural cycle by cutting more plants.
Burning coal, oil and natural gases are the main cause of global warming. CO2 gas acts as a blanket which retains environmental heat and warms the earth’s surface. The level of carbon dioxide has become increased to a great level in last century. The earth surface has become successively warmer than ever in the last three decades. Each month is becoming warmer than ever which we can feel very clearly. This increasing heat affecting the lives of human beings, plants and animals even many species have been endangered.
