Question

Explain the following term/process in detail:
Global Warming

Answer 1

• Global Warming: The temperature on the earth is rising. This phenomenon known as Global Warming is the result of enhanced concentration of Greenhouse gases in the atmosphere caused mainly by human activities. Consequences of Global Warming:

1. Global temperature is likely rise by 2 to 5°C during the next century. Due to rise in temperature by 2 to 5°C, there is a chance of melting of ice caps on Earth’s poles. This melting of ice will result in the rise of the sea level. Large stretches of low lying areas will submerge and many island countries will face deep encroachment by seawater. Some may disappear altogether.
2. As the increase in temperature will be uniform all over the surface of the world, there will be serious climatic changes. This will bring various changes in wind and rain patterns.
3. Higher temperature will cause rise in transpiration, which in turn, will affect the groundwater table.
4. As the climatic belts shift from equator towards pole, the vegetation would also shift away from the equator.
5. Insects and pests will increase in the warmer climatic conditions. Thus, pathogenic diseases will multiply.
