In An Inconvenient Truth, the graph shows a regular decrease in atmospheric carbon dioxide once a year. This happens during winter and spring in the Northern Hemisphere.

Answer 3

[AI-generated answer — Explain Bot]

To determine the correct answer, we can analyze the information given in the question and apply our understanding of seasonal changes.

The graph of atmospheric carbon dioxide in the question shows a regular decrease in the amount of gas once a year. This implies that there is a consistent pattern to this decrease.

Based on the options provided, we need to determine which time of year in the Northern Hemisphere aligns with a regular decrease in atmospheric carbon dioxide.

During the summer and fall in the Northern Hemisphere, there tend to be higher levels of carbon dioxide in the atmosphere due to factors such as increased plant respiration and decreased photosynthesis. Therefore, it is unlikely that this period corresponds to a regular decrease in atmospheric carbon dioxide.

Fall and winter in the Northern Hemisphere typically experience colder temperatures, which can lead to a decrease in plant respiration and consequently a decrease in carbon dioxide levels. This aligns with the pattern described in the question.

Spring and summer in the Northern Hemisphere see a boost in plant growth and photosynthesis, which normally leads to increased carbon dioxide absorption and lower levels of atmospheric carbon dioxide. Again, this contradicts the pattern of regular decrease mentioned in the question.

Therefore, the correct answer is fall and winter in the Northern Hemisphere.
