The correct answer is A. Recent high temperatures are caused by human activities.
Explanation
The graph shows the agents of climate change. In the first row are the natural processes, in the second row are human activities concerning thermal interruption (W / m²), and in the third row is the accumulated total of human activities that reach close to 2 W / m², while natural processes are close to 0.3 W / m². Therefore, it is possible to affirm that the increase in temperature is mainly caused by human activity, so the correct answer is A. A. Recent high temperatures are caused by human activities.
