The Truth About Global WarmingThe Truth About Global Warming


1. What is the effect of the three rhetorical questions in the first paragraph? (1 mark)

The three rhetorical questions help to focus the reader’s attention on the main issues to be discussed in the passage.


2. What is the passage about? (1 mark) The passage is about how much

human action is to blame for the state of global warming and whether the causes that we have been hearing about are valid or not.

The Truth About Global WarmingThe Truth About Global Warming Yes it is significant because it seems to

have large repercussions in the ecological environment. A seemingly small average temperature change actually has a big climatic impact.

Hence over time, these small changes affect habitats of animals (tropical fishes moving northwards) and these then impacts on ecology; once the ecological balance is affected then other problems crop up.

Temperature decrease during the Ice Age which wiped out the world’s population.


4. What is so bad about “unstable permafrost in the Baikal area, Mongolia and China”? (1 mark)

danger of rising humidity May lead to flooding Unbalanced ecosystem Unstable construction/buildings


5. Why are there brackets around these words [of human- produced greenhouse gases] – in paragraph 17 (1 mark).

This is an academic convention to fill in some missing information that is not otherwise captured in the quotation.


6. What is the greenhouse effect? (1 mark)

Just as a greenhouse traps air inside a glass structure and lets the sun’s rays warm it up, so in the greenhouse effect, air is trapped under the Earth’s atmosphere and warms up. However, if this air gets too hot then life on earth will begin to become uncomfortably hot.

The Truth About Global WarmingThe Truth About Global Warming7. What’s convincing scientists that carbon dioxide is

responsible for the recent warming? (4 marks)

What seems to be convincing the scientists that CO2 is responsible for global warming is that this is the only gas that man produces quite a lot of (23.5 gigatonnes) annually and this seems to heat up the climate more according to Thomas Karl who is the Director of an environmental institute in America.. There appears to be evidence supporting this according to several scientific studies from other scientists like Professor Rahmstorf who has researched on rising temperatures and Professor Wunsch who researches in a similar field in America.


8. Would it be a problem if in 2008, carbon dioxide emissions were 10% higher than in 2007? (1 mark)

Yes it would because CO2 does not dissipate completely in the carbon cycle, only 50% will be recycled by plants into oxygen, while the other 50% remains possibly in the oceans where it turns into carbonic acid which would then affect marine life.


9. Explain the analogy between buying home insurance and taking immediate action against global warming (2 marks).

When one buys insurance one spends the money to protect the home but one does not expect to benefit from the insurance pay out because one would much prefer that the home did not burn down or be destroyed in any way. Thus in the same way, we should take preventative measures about climate change rather than suffer from any ill effects from it.

The SQ4R strategy is built around the idea that what you do before and after you read is as important as the reading itself.

Understanding and using the SQ4R strategy will increase your comprehension and your retention of the information.
