the data in the graph support which of the following statements?
a. there is no reason to believe humans are causing global warming.
b. natural weather patterns are evidence against global warming.
c. natural processes have a greater impact on global warming.
d. human activity has a greater impact on global warming.

Explanation:

The graph shows positive thermal disruptions (warming effect) from human - related greenhouse gases like CO₂, halocarbons, and ozone. The net change due to human activities is also positive, indicating warming. In contrast, natural processes have a much smaller impact on thermal disruption.

Answer:

D. Human activity has a greater impact on global warming.
