Question

Global warming 10 lines

Answer 1

Global warming is a gradual increase in the temperature of the earth surface and atmosphere all around the world. It is caused due to the greenhouse effect of increased level of green house gases such as carbon dioxide, CFCs, etc. There are various types of pollutants also which involved in increasing the atmospheric temperature of the earth. Increasing use of fossil fuels by the people and deforestation is increasing carbon dioxide emissions which trap heat and cause greenhouse effect.

Water vapor is also a significant greenhouse gas which is not directly produced by humankind but involve in global warming hugely. A slight increase in the level of CO2 causes marked increase in earth temperature. Green house gases absorb and re-radiate infrared radiations which ultimately cause green house effect. Because of deforestation, CO2 is not absorbed well and remain in the atmosphere for long time and trap heat.

Answer 2

1) Global warming refers to the above average rise of earth’s temperature.

2) Global warming is caused due to green house effect.

3) Gases like carbon dioxide (CO2) and Methane (CH4) play vital role in causing green house effect and subsequently global warming.

4) Industries emitting CO2 as byproduct add to the global warming.

5) Earth’s temperature ahs warmed up by 0.9°Celsius (33.62 degree Fahrenheit) since 1901.

6) Deforestation and suspended particulate matter also play their part in global warming.

7) Global warming results in extreme climate changes.

8) Global warming causes melting of glaciers and rise in sea level.

9) It causes disturbance in monsoon patterns.

10) Causes more frequent occurrence of draughts and unexpected climatic changes.
