Question

Review the data table below. Answer the questions that follow (in your own words.)

Column 1| Column 2 | Column 3
Year | Atmospheric Carbon Dioxide Concentration(ppm)| Global Population (billions)
1920 | 303 | 1.86
1940 | 310 | 2.30
1960 | 316 | 3.03
1980 | 339 | 4.43
2000 | 369 | 6.12
2020 | 412 | 7.79



For this question, please answer the following: 1. Describe the overall pattern/trend you see in columns 2 and 3. Include in your description: a) what is being measured in each column and b) state two specific data points from Columns 2 and/or Column 3. 2. Next, describe the relationship of the data in column 2 and column 3 (in other words, how is the pattern in column 2 related to the pattern in column 3?). 3. Explain why the data in column 2 and column 3 are related in the way you described in part 2. You are making a hypothesis/educated guess here! 4. State the actions that could be taken to slow or reverse the pattern/trend in column 2. Grading Considerations: All 4 parts should be answered. Be sure to include parts a and b in part 1. Create a list numbered 1-4 in your answer to ensure you answer all parts! Answers should be in complete sentences. Answers longer than 8 sentences will not be considered. Answering concisely and to the point is evidence for your understanding of the topic. (4 points)

Answer 1

1. The overall trend in Column 2 shows a significant increase in atmospheric carbon dioxide concentration (measured in parts per million, ppm) over the years, rising from 303 ppm in 1920 to 412 ppm in 2020. In Column 3, the global population (measured in billions) also exhibits a consistent upward trend, increasing from 1.86 billion in 1920 to 7.79 billion in 2020. Notably, the decrease in carbon dioxide concentration from 1920 to 1940 was followed by a steady rise thereafter, paralleling the population growth.

2. The data in Column 2 and Column 3 appear to be related; as the global population has increased, the atmospheric carbon dioxide concentration has also risen. Specifically, both values show a pattern of growth, suggesting a connection between higher populations and increased carbon emissions.

3. This relationship can be hypothesized to stem from the greater demands for energy and resources resulting from a larger population. Increased industrial activities, transportation needs, and energy consumption typically accompany population growth, leading to a rise in carbon emissions, thereby elevating atmospheric CO2 levels.

4. To slow or reverse the increase in atmospheric carbon dioxide, actions could include implementing renewable energy sources, promoting energy efficiency, and encouraging sustainable agricultural practices. Additionally, initiatives to reforest and protect existing forests, alongside policies aimed at reducing fossil fuel consumption, would also contribute to lowering CO2 concentrations.
