Extremes of Summer Insolation in the Northern Hemisphere of the Earth and Global Climatic Events of the Holocene

Abstract

The synchronicity between the extreme values of summer insolation in the northern hemisphere and the global climatic events of the Holocene is found. The transition from the cold Pleistocene to the warm Holocene epoch is synchronized with the summer irradiation maximum. The Little Ice Age is synchronized with the minimum of summer irradiation in the northern hemisphere. For the Holocene and Late Pleistocene, the leading role of climatic precession in changes in the global climate of the Earth has been determined. Accounting for variations in solar activity made it possible to detail the structure of the minimum irradiation of the northern hemisphere during the Little Ice Age. The necessity and possibility of simultaneously taking variations in incoming radiation of different physical nature associated with changes in the Earth’s orbital motion and changes in the activity of the Sun into account are shown in the reconstruction and forecasting of global climatic events.
