If researchers never evaluated the amount of ¹⁴C in the atmosphere, they could still use ¹³C levels to demonstrate causation between human activities and increased atmospheric CO₂.

Question

Quizplus · Accepted Answer

The statement is incorrect because both ¹³C and ¹⁴C are isotopes of carbon dioxide, and their levels in the atmosphere are affected by both natural and anthropogenic activities. Therefore, in order to definitively attribute changes in atmospheric CO2 to human activities and establish causation, scientists need to measure the specific isotopic ratios and evaluate any changes over time.
