Question

Quizplus · Accepted Answer

The IPCC Fifth Assessment Report states that humans are likely responsible for the temperature increase from 1951 to 2010 with 95% certainty. Therefore, option C is the correct answer. Options A and B are incorrect as they contradict the findings of the report. Option D is also incorrect as it implies there is no consensus, whereas the report clearly states that there is a consensus that human activity is a significant driver of climate change.
