The greenhouse effect: fact or invention?

Living beings need energy to survive. The energy that life on the Earth receives comes from the Sun. Due to its enormous heat, it radiates energy into space. A tiny part of this energy reaches the Earth.

The atmosphere of the Earth acts as a protective blanket over the surface of our planet, preventing the temperature fluctuations that would occur in an airless world.

A large part of the incoming solar energy penetrates through the Earth's atmosphere. The Earth absorbs a part of this energy, and another part is radiated back from the Earth's surface. This reflected energy is partially absorbed by the atmosphere.

As a result, the average temperature above the Earth's surface is higher than it would be if there were no atmosphere. The Earth's atmosphere has the same effect as a greenhouse, hence the term greenhouse effect.

The greenhouse effect is said to have intensified in the 20th century.

The fact is that the average temperature of the Earth's atmosphere has increased. In newspapers and magazines, the main reason for the rise in temperature in the 20th century is often stated to be the increased carbon dioxide emissions.

The student Alex begins to be interested in the possible connection between the average temperature of the Earth's atmosphere, and the emissions of carbon dioxide on the Earth. In a library, he finds the following two graphical representations.

Your classmate Alex concludes from these two graphical representations that the increase in the average temperature of the Earth's atmosphere is most certainly due to the increase in carbon dioxide emissions.

Kate, another student, disagrees with Alex's conclusion. She compares the two graphs, and says that some sections of the graphical representations do not support his conclusion.

Choose the answer that does not support Alex's conclusion.

The temperature in the 19th century remained pretty much the same, but the first graph continues to rise.

Between 1950 and 1980, the temperature did not rise, but the carbon dioxide emissions rose.

The temperature rises when CO2 is emitted.

Everything is rising.

The information lines on the graphs rise together.

As emissions increased, the temperature increased.
