Answer :
If you were working with Dr. Keeling in the 1950s, an appropriate hypothesis for his research would be:
C) If carbon dioxide levels in the atmosphere increase, then average annual temperatures on Earth will increase.
This hypothesis is focused on the relationship between carbon dioxide levels in the atmosphere and average annual temperatures on Earth. It proposes a cause-and-effect scenario where an increase in carbon dioxide levels leads to a corresponding increase in average annual temperatures. This hypothesis aligns with Dr. Keeling's pioneering work on the Keeling Curve, which demonstrated the rising trend of carbon dioxide levels in the atmosphere.
By formulating this hypothesis, Dr. Keeling could design experiments or collect data to test the impact of changing carbon dioxide levels on Earth's temperatures. This hypothesis sets a clear direction for research and allows for the investigation of a significant environmental issue related to climate change.
Overall, hypothesis C provides a specific and testable statement that guides scientific inquiry into the relationship between carbon dioxide levels and global temperatures, reflecting the essence of Dr. Keeling's influential research in the field of climate science.
