Question

the data in the graph support which of the following claims?
a. human activity is the main influence on recent climate change.
b. natural processes are the main cause of rising global temperatures.
c. human activity and natural processes cancel each other out.
d. natural processes have a small cooling effect on climate change.

Explanation:

The graph shows that human activities (such as from greenhouse gases like \(CO_2\), halocarbons, ozone) have a warming effect. The "Net change due to human activities" bar is positive (warming), while the "Net change in energy from Sun" (a natural process - the first bar) has a very small warming effect compared to human - related factors. Natural processes (the first bar) do not have a significant warming or cooling effect in terms of being the main cause. Also, human activities are not canceled out by natural processes as the net human - related change is positive.

Answer:

A. Human activity is the main influence on recent climate change.
