The Problem of Meridional Heat Transport in the Astronomical Climate Theory

The reduction of solar radiation arriving in the summer half of the years by 65° N has been found to be a consequence of decreased inclination of the rotation axis and increased meridional contrast in insolation, rather than a result of climate cooling. Thus, the astronomical climate theory involves a paradox related to the fact that the change in the meridional heat transfer due to a change in the inclination of the rotation axis is disregarded. In this context, the mechanism of the astronomical chronology of climatic events in the Pleistocene needs to be revised.
