Everything else being equal,a gradual increase in global CO₂ would most likely bring about A) an increase in surface air temperature. B) a marked decrease in plant growth. C) a decrease in evaporation from the earth's oceans. D) no change in global climate.

Question

Quizplus · Accepted Answer

CO₂ (or carbon dioxide) is a greenhouse gas that traps heat in the atmosphere. Therefore, an increase in its concentration would result in an increase in surface air temperature. This is because more heat would be trapped in the atmosphere, resulting in global warming. There is also evidence that higher CO₂ levels can affect plant growth and decrease oceanic evaporation, but the most significant impact would be on global temperature. Overall, choice A is the best answer.
