The right response is A. Human activities are the cause of the recent high temperatures.
The burning of fossil fuels, logging of forests, and raising of livestock all have a rising impact on the climate and temperature of the planet. As a result, the amount of greenhouse gases in the atmosphere that are already there naturally increases, contributing to the greenhouse effect and global warming.
The graph missing in the query is attached below:
The agents of climate change are depicted in the graph. Natural processes are shown in the first row, human thermal interruption (W / m2) activities are shown in the second row, and the entire cumulative amount of human activities, which is near 2 W / m2, is shown in the third row, whereas natural processes are close to 0.3 W / m2. Therefore, it is possible to state that human activity is the primary reason of the temperature increase, making answer option A. Recent high temperatures are a result of human activity.
