Why Milankovitch Cycle Theory Is Like Astrology

Sometimes a hunch proves to be unworkable. The Milankovitch Cycle theory has too many complications. It’s time to give it up. In the 1920s, Milutin Milankovitch, a Serbian astronomer, mathematician and popularizer of science, had a bright idea. Knowing that certain orbital cycles drift over time, he wondered if they could influence the earth’s climate. […]
