Question

Which of the following is/are the advantages of global warming?
A. Arctic, Antarctic, Siberia, and other frozen regions of earth may experience more plant growth and milder climates.
B. The next ice age may be prevented from occurring.
C. Less need for energy consumption to warm cold places.
D. All of the above.

Answer 1

Hint:By definition, global warming means an increase in earth’s temperature due to trapping of greenhouse effect which is caused by trapping of gases like carbon dioxide, CFCs, methane and other pollutants. It has many advantages as well as many disadvantages. It increases heat related illness and deaths. On the other hand, it also increases the growing season which means increased agricultural production.We need to read every option and try to analyze them and figure out if they are advantages of global warming.

Complete answer:
Global warming is heating up the earth's surface due to trapping of greenhouse gases like methane, CFCs, carbon dioxide and other pollutants. The substantial increase in the earth's temperature in recent years is an effect of global warming.

Now let us read every option one by one and understand and analyze them.
Option A: Arctic, Antarctic, Siberia, and other frozen regions of earth may experience more plant growth and milder climates.
Yes, this is clearly an advantage. The climate of the frozen regions is very extreme. Global warming makes them milder and due to which there will be increased plant growth in those regions.

Option B: The next ice age may be prevented from occurring.
Because of global warming, there is a boost in the carbon dioxide levels in the atmosphere which reduces the cooling. Therefore, it may have prevented the ice age.

Option C: Less need for energy consumption to warm cold places.
Since global warming produced substantial increase in the temperature, it has already warmed up the cold places. Therefore, we wouldn’t require any extra energy to warm the cold places. Therefore, all the options are correct.

Hence, the right answer is option D.

Note:We need to know the definition of global warming to answer this question correctly. We should read every option and understand them and analyze them properly. We also need to realize that no matter how many advantages global warming has, it has many negative effects as well. So, we need to prevent global warming by not using CFCs, planting more trees etc.
