I also went to that Wikipedia page. The “multiple possible / probable causes” listed are: “orbital cycles; decreased solar activity; increased volcanic activity; altered ocean current flows; fluctuations in the human population in different parts of the world causing reforestation, or deforestation; and the inherent variability of global climate change” Only one of those is human related. Bizarre.
