​THE ENHANCED GREENHOUSE EFFECT: FACT OR FICTION?
The energy that sustains most living things on Earth comes from the sun's radiation. The Earth's atmosphere acts like a protective blanket around our planet, allowing the sun's radiation to pass through and absorbing some of the energy radiated back from Earth that would otherwise escape. As a result of this, the average temperature of the Earth's atmosphere is higher than it would be if there were no atmosphere to trap the heat energy. The Earth's atmosphere thus has a similar effect to a greenhouse where the glass of the greenhouse traps heat energy from the sun and keeps the inside warm. The data indicate that the average temperature of the Earth's atmosphere has significantly increased over the last century. The reason for this average temperature increase is said to be because of increased atmospheric carbon dioxide, which causes the atmosphere to more effectively trap heat - the greenhouse effect is thus enhanced by CO2. André, a student, becomes interested in the possible relationship between the average temperature of the Earth's atmosphere and carbon dioxide emission on Earth.
André comes across two graphs on a Government website. He concluded from these two graphs that it is certain that the increase in the average temperature of the Earth’s atmosphere is due to the increase in the carbon emission.
What about the graphs supports André’s conclusion?

Another student, Jeanne, disagrees with André’s conclusion after comparing the two graphs.
Give an example of a part of the graphs that does not support André’s conclusion. Explain your answer.

AndrĂ© persist in his conclusion that the average temperature rise of the Earth's atmosphere is caused by the increased in carbon dioxide emission. But Jeanne thinks that his conclusion is premature. She says: "Before accepting this conclusion, you must be sure that other factors have not caused it."Â
Name one other factor that could have caused the mean temperature on the earth to vary:
For scientists to decide whether the rise in the average temperature is caused by increased emissions of carbon dioxide, which (one or more) of the following would be considered important to establishing a strong case:
In pursuing their different ideas and trying to find out who is correct, André and Jeanne research different sources of information, listed below. Tick those which you think are most trustworthy.
In debating the issue, André and Jeanne discuss whether scientists’ studies about climate change are influenced by political and social pressures and opinions. Which two of the following scientific practices are the most important for ensuring that scientific findings are reliable?
