The Innovation： Low-latitude forcing: A new insight into paleo-climate changes

PinxianWang11 State Key Laboratory of Marine Geology, Tongji University, Shanghai 200092, ChinaMain textThe origin of glacial cycles is central to paleo-climate research. A major breakthrough of Earth science in the 20th century was the discovery of orbital forcing of the glacial cycles, known as the Milankovitch theory. The periodicity of the glacial cycles over the last million years was successfully explained by the variations of June solar insolation at 65°N. In responding to the changes in
