a) Nitrogen
b) Carbon monoxide
c) Carbon dioxide
d) Hydrogen
Answer: c
Clarification: Carbon dioxide is an important heat trapping gas. It is released through human activities such as deforestation and burning fossil fuels, as well as natural processes such as volcanic eruptions and respiration.
2. How many cubic kilometers of land ice decrease in Antarctica since 2002?
a) 100
b) 400
c) 500
d) 1000
Answer: a
Clarification: Decrease in land ice is one of the effects of climate change. The continent Antarctica has been losing more than 100 cubic kilometers of ice per year since the year 2002. These decreases in land ice result in the increase of sea level.
3. Which one of the following is the reason for a sea level rise?
a) Depression of sea water
b) Expansion of sea water
c) Due to heavy rainfall
d) Due to low rainfall
Answer: b
Clarification: Sea level rise is caused by the expansion of sea water. Sea water as it warms up due to sunlight it response to climate change and the widespread melting of land ice. Sea level rise consumes the coastal lands and islands.
4. What is the full form of IPCC?
a) Intergovernmental Panel on Climate Change
b) International Panel on Climate Change
c) Intergovernmental Protocols on Climate Change
d) International Panel on Climate Conservation
Answer: a
Clarification: IPCC stands for Intergovernmental Panel on Climate Change. It reviewed the results of several experiments in order to estimate changes in climate in the course of this century. These studies shown that, the mean average temperature will rise by 1.4 to 5.8 degree Celsius.
5. What is the estimation range of the global mean sea level rise by the year 2100?
a) 0-10 cm
b) 4-45 cm
c) 9-88 cm
d) 14-123 cm
Answer: c
Clarification: The global mean sea level is projected to rise by 9-88 cm by the year 2100. This cause various problems to humans as more than half of the world’s population now lives within 60 km of the sea.
6. Human society can sustain any kind of climate change.
a) True
b) False
Answer: b
Clarification: Human societies will be seriously affected by extremes in climate. Some of the climatic extremes which lead to droughts and floods will cause great damage to human society. This is also a fundamental concern for human health.
7. According to the World Health Organization estimation in 2001, which one of the following is the most vulnerable region for a rise in sea level?
a) Srilanka
b) Andaman and Nicobar
c) Ganges–Brahmaputra delta
d) Kutch
Answer: c
Clarification: According to World Health Organization, Ganges-Brahmaputra delta in Bangladesh is the most vulnerable region for rise in sea level among the above given options. They cause various problems for vegetations and as well as for organisms.
8. Which one of the following is a result of climate change?
a) Adequate rainfall
b) Pure air
c) Deficiency of freshwater
d) Less soil pollution
Answer: c
Clarification: Freshwater supplies may be seriously affected due to climate change. Reducing the availability of clean water for drinking leads to the death of humans and as well as animals. It leads to drought condition.
9. How food production reduced due to climate change?
a) Due to application of organic manures
b) Due to modern technologies
c) Due to increase in pests
d) Due to reduced in pollution
Answer: c
Clarification: Food production will be seriously reduced in vulnerable regions directly and also indirectly through an increase in pests and plant or animal diseases. This leads to reduce in the yield of crops and the quality of the crops also reduced.
10. How climate change leads to conflicts in vulnerable regions?
a) By shortage of human resources
b) By shortage of food and water
c) By shortage of land
d) By shortage of chemical manures
Answer: b
Clarification: Food and water shortages may lead to conflicts in vulnerable regions. Due to shortage of food and water both animals and humans suffer from starvation and malnutrition with long term health consequences.
11. What happens when seasonal transmission of vector species due to climate change?
a) Increase the spread of diseases
b) Decreased the spread of diseases
c) Vector species itself die
d) Vector species do not spread disease
Answer: a
Clarification: Due to change in climate vector species like mosquitoes, will increase the spread of diseases, such as malaria, dengue etc to new areas which lack good public health infrastructure and cause problems.
12. Which one of the following can achieve Global Climate Change?
a) World War-3
b) Making unwanted policies
c) Drinking less water than required
d) The training of researchers and health professionals
Answer: d
Clarification: The training of researchers and health professionals is essential towards the world becoming more responsible for the expected outcome of Global Climate Change. Thus we can protect the environment.
13. In which year the Pacific Ocean led to the most serious death in coral ever known?
a) 1993
b) 1995
c) 1997
d) 2000
Answer: c
Clarification: In 1997, the severity of periodic warming in the Pacific Ocean led to the most serious death in coral ever known. It is estimated that about 10% of the earth’s coral reefs were dead and another 30% were seriously affected.
14. World Health Organization warned that climate change may have a serious affect on human health.
a) True
b) False
Answer: a
Clarification: World Health Organization set up a task group which warned that climate change may have a serious affect on human health. Climate change will increase existing health problems and may also bring new heath problems.
