Question

Discuss the causes and effects of global warming. What measures need to be taken to control global warming?

Answer 1

it deplets ice caps and then it mixed with sea water and that water we can't drink . it is caused cutting of trees and increase in amount of co2 and chlorofluorocarbons

Answer 2

Answer:

An increase in the average temperature of the surface of earth is termed as Global warming. It can be caused due to the following reasons:

Increased concentration of the greenhouse gases in the atmosphere of the earth causes the phenomena of global warming. These gases are methane, carbon dioxide and water vapor which trap solar rays that are given out by the Earth helping to keep the planet warm, thus aiding human survival. Rise in the level of these greenhouse gases can cause a huge increase in the temperature of the Earth resulting in Global warming

Global warming can also be caused due to burning of fossil fuels, industrialization and the act of deforestation

Impact of Global warming:

It has been observed over the past few decades that global warming has led the average temperature of the Earth to increase by 0.6 ˚C, causing a disturbance in the natural water cycle, hence fluctuations in the pattern of rainfall. These changes also have an impact on the rainfall.

Global warming has also caused the polar ice caps and mountain glaciers to melt, leading to an increase in the sea level, hence the inundation of coastal areas.

Preventive measures:

Use of fossil fuels must be reduced

Increase the usage of bio-fuels

Switch to renewable source of energy such as CNG

Promote reforestation

Encourage and carry out recycling of materials

Energy must be efficiently used
