Discuss the causes and effect of global warming what measures need to be taken to control global warming
Answers
Answer:
Global warming is projected to have a number of effects on the ocean. Ongoing effects include rising sea leavels due to thermal expansion and melting of glaciers and ice sheet, and warming of the ocean surface, leading to increased temperature stratification.
To controle global warming follow the steps:-
1. Plant maximum numbers of trees as they releases oxygen absorbs CO2 present in atmosphere. In this way a tree balance the temperature of air and reduce the amount of CO2 present in air.
2. Vehicles release many harmful gases in air. we should minimum use of vehicals .
3. Use fans more than air conditions . Hot air release from air conditioner is major problem of global warming .
4. Instead of dryers take an advantage of sun to dry wet cloths.
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
