Question

question 4 of 27
the graph below shows forces affecting climate change. which claim does
the graph support?
chart: agents of climate change, with natural processes (net change in energy from sun), human activities (co₂, halocarbons, ozone, greenhouse gases, total aerosols, net change due to human activities); warming effect (brown), cooling effect (blue)

a. natural processes are the primary force affecting climate change.
b. human activity is the primary force affecting climate change.
c. human activity and natural processes have equal effects.
d. natural processes are a tiny cooling force on climate change.

Explanation:

To determine which claim the graph supports, we analyze the visual data:

• For natural processes (Net change in energy from Sun), the thermal disruption is small (near 0, warming effect).
• For human activities, the "Net change due to human activities" has a significant warming effect, and individual human - caused factors (e.g., CO₂, Halocarbons, Ozone as warming; Total aerosols as cooling, but net human effect is still significant).
• Option A: Natural processes have a small effect, not primary. Eliminate.
• Option B: Human activity (net change and individual factors) has a more significant impact than natural processes, so it is the primary force.
• Option C: Effects are not equal (human effect is larger). Eliminate.
• Option D: Natural processes here have a tiny warming (not cooling) effect. Eliminate.

Answer:

B. Human activity is the primary force affecting climate change.
