Refer to the graph, showing a continual increase in CO₂ since measurements began about 1960. In addition to the data plotted in the graph, data from air trapped in ice caps show that CO₂ levels have been strongly correlated with atmospheric temperatures for hundreds of thousands of years.What is one conclusion that might be drawn from these two sets of data? A) Adding CO₂ to the atmosphere is raising global temperatures. B) Adding CO₂ to the atmosphere is lowering global temperatures. C) CO₂ levels can be controlled by stopping CO₂ measurements. D) CO₂ levels can be controlled by controlling global temperatures. E) The most likely way to control CO₂ is by controlling rates of photosynthesis.

Question

Quizplus · Accepted Answer

The data shows a strong correlation between increasing CO₂ levels and rising atmospheric temperatures, both over the past few decades and over hundreds of thousands of years. This suggests that adding CO₂ to the atmosphere is contributing to global warming. The other choices are not supported by the data or are not relevant to the question.
