The temperature of the earth is continuously increasing due to the pollution and deteriorating environmental balance of the whole world, and this phenomenon is called Global Warming. Greenhouse gases have an important role in this process of global warming. In these, carbon – dioxide gas is the most responsible causative factor.
Due to being heavy, this gas accumulates in the form of a layer in the lower part of the atmosphere near the earth’s surface. Due to the formation of this layer of gas, the thermal radiation from the earth is reflected back to the earth. As a result, the temperature on the earth increases. In this way, the process of increasing temperature has emerged in the form of Global Warming.
Effects of Global Warming: There are many effects of the global warming.
The description of these effects is as follows:
1. There will be major changes in the climate due to the increase in temperature. The discrepancies seen in the weather and seasonal cycle in the present time are the result of this.
2. There will be a vast change in the nature of rainfall due to the increase in temperature of the earth. The evaporation will be more from aquatic parts due to the increased temperature. More temperature and evaporation result in more rainfall. Consequently, the cycle of season will change. The period of summer season will increase and that of the winter season will decrease.
3. There will be an increase in the El – Nino effect and in the frequency of cyclones due to global warming.
4. There will be rise in the water level of sea by the melting of snow in polar regions and mountain peaks due to the increase in average temperature of the world. Consequently, the coastal parts will be submerged. Islands located in the oceans will sink.
5. Snow of glaciers will melt in more amount due to increase in temperature. As a result, the increase in the amount of water in the rivers can result in severe flooding.
6. The most significant impact of the change in the cycle of season, which will occur due to the increased temperature, will be on agriculture. Due to this, the format and systems of agriculture will change.
7. Due to the increased temperature, the existence of living organisms, plants and trees will become threatened.
