Global Warming Questions and Answers Class 8th

The term global warming refers to the general increase in the average temperature of the earth caused by the presence of greenhouse gasses in the atmosphere, causing changes in climate patterns throughout the globe.


Global Warming is one of the major threats to the human race. It refers to the rise of about 0.80C. Its main reason is the increase in the greenhouse gases produced by human activities. Global Warming will increase sea water levels and cause extreme weather events including heat waves, droughts, and heavy rainfall.

Global Warming will melt all the glaciers in the Himalayan region and change the livelihood of millions of people of the subcontinent.

Even place like Kashmir will have an impact of this warming. Glaciers in Jammu and Kashmir are receding at an alarming rate. This has resulted in water scarcity and increased the threat of floods. Global warming has brought in high-velocity storms in the valley which have caused devastation to crops and fruits. The rapid melting of Kolhai glacier by 18% has evoked concern among environmentalist. This is mainly due to increase in temperature, caused by high levels of the population from various sources. The observation made by TERI has shown increased discharge trends due to increase in glacier melt runoff.

Global Warming has brought great changes in climate. The average temperatures have increased. The research carried out by the University of Kashmir has shown that the average increase in temperature in the valley by the end of the 21st century would be between 2 and 3 centigrade. Erratic snowfall, hotter summers, climate variability and change in precipitation levels will affect livelihoods. So, we need to come up with a strategy for the sustainable development of water resources in the region. Our children will curse as if we don’t do it now.

Q.1 Why has the Earth’s average surface temperature increased?

Ans: One of the major reasons for the increase in the Earth’s average surface temperature is the increasing concentrations of greenhouse gases produced by human activities such as deforestration and burning of fossil fuels. The increase in the carbon footprint by the developed and the developing countries is one of the major causes of global warming.

Q. 2 Why is the Himalayan region called the Water Tower of Asia?

Ans: The Himalayan region is called the Water Tower of Asia because it has a glacial coverage of 33000 square kilometers and it provides around 8.6 million cubic meters of water per annum to Asian countries.

Q. 3 What are the main sources of water in the Kashmir Valley?

Ans: The main sources of drinking water and irrigation in the Kashmir Valley are glaciers which feed most of the rivers and streams.

Q. 4 Why is water the most precious natural resource?

Ans: Life in general not possible without water. Water is required for animals and crops to grow. Thus water sustains life besides presenting itself as one of the major energy resources in the formation of electricity.

Q. 5 How has Kashmir been influenced by global warming?

Ans: Due to global warming, the glaciers in Kashmir are receding at an alarming rate. We have lost 18% of the Kolhai glacier, and about 16% of the glaciers in Suru basin. Besides this Kashmir is witnessing reduction in snowfall, occurance of high velocity wind storms, and drastic changes in prespitation and seasonal changes.

Q. 6 How is global warming the largest threat to humanity?

Ans: Global warming is catastrophic because it is going to render earth barren. Global warming is going to bring droughts, heatwaves and heavy downpour which will have disastrous consequences on the agricultural yields and consequently lead to species extinction. According to Noam Chomsky, after nuclear bomb environmental degradation is the second largest threat faced by man.

Q.7 What do you think is the cause of decrease in snowfall in Kashmir?

Ans: Ans. Global warming is the certain cause of the reduction in snowfall in Kashmir because global warming changes the precipitation patterns and thus leads to weather and eventually climate change.Thus, the main cause behind the decrease in snowfall in Kashmir is global warming.

Q. 8 What has been the impact of global warming on J&K so far?

Ans: Due to global warming, the glaciers in J&K are receding at an alarming rate as compared to other glacial regions in the world. J&K has lost about 18% of the Kolhai glacier and about 16% of glaciers in Sure basin alone in the last forty years.

Q. 9 What role do scientists play in J&K to deal with the global warming?


ii. Let’s discuss about making excuses
iii. She is unbeatable in arguing.
