The root cause for the increase in temperature is called as GLOBAL WARMING or CLIMATE CHANGE.
-Why does it occur?
It is due to increase in usage of substances that cause damage to ozone layer and earth!
These substances which cause global warming are known as green house gases and they include Carbon dioxide (CO2) and air pollutants.
These gases cause rise in temperature and cause climate change!
Also , due to rise in temperature, the icebergs and north pole areas get melted and sea level rises and causes disturbances.
Measures to prevent Climate Change:-
1)We must start afforestation and stop deforestation
2)We must use resources which don’t pollute the atmosphere
3) We must use vehicles which are run on CNG and LPG
4) We must not burn fossil fuels instead we must convert to renewable resources.
