Definetion :-
The warming of the atmosphere whichvis due to our influence on the greenhouse effect is known as global warming.
Explanation :-
The increasing use of fossil fuels and the deforestation have led to an increase in the levels of CO2 in the air.Gases like water vspour,methane and CFCs also act in a similar way in the atmosphere. These gases are called green house gases.
The higher the concentration of green house gases in the air,the greater is the green house effect, and greater will be the increase in temperature.
Certain human activities are threatening to cause a significant increase in the greenhouse effect.
Global warming is due to an upset in the natural balance of the concentration of greenhouse gases in the atmosphere.
If global warming continues,then
●Temperature of the earth will gradually increase.
●Polar ice may melt and cause significant increase in sea levels.
●So the atmosphere becomes hotter.
●The earth climate may change,affecting both where there is rainfall and how much there is of it.This could cause both increased risk of flooding in some regions and drought in others.
