Question

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

Column 1 Column 2 Column 2
Year Atmospheric Carbon Dioxide Concentration (ppm) Global Populations (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

Answer 1

1. The overall trend in columns 2 and 3 indicates an increase in both atmospheric carbon dioxide concentration and global population over time. a) Column 2 measures the concentration of atmospheric carbon dioxide in parts per million (ppm), while column 3 measures the global population in billions. b) For instance, in the year 1960, the CO2 concentration was 316 ppm, and the global population was 3.03 billion. By the year 2020, the CO2 concentration rose to 412 ppm, and the population increased to 7.79 billion.

2. The relationship between the data in column 2 and column 3 shows that as the global population increases, the atmospheric carbon dioxide concentration also tends to rise. This pattern suggests a correlation between population growth and CO2 levels.

3. The data are likely related because a growing population typically leads to higher levels of emissions from activities such as transportation, industry, and energy consumption. More people require more resources, which in turn can result in increased greenhouse gas emissions, including carbon dioxide.

4. To slow or reverse the trend of increasing atmospheric carbon dioxide, actions could include promoting renewable energy sources to reduce fossil fuel use, implementing stricter emissions regulations, and encouraging energy efficiency in industries and transportation. Additionally, initiatives for reforestation and afforestation could help absorb CO2 from the atmosphere.
