The report’s authors, however, say the factors driving climate change are quite clear.

“Many lines of evidence demonstrate that human activities, especially emissions of greenhouse gases, are primarily responsible for the observed climate changes over the last 15 decades,” the authors wrote. “There are no alternative explanations.”
