Аnnotation: Peculiarities in the change in the specific energy of irradiation and the intensity of irradiation in the latitudinal zones of the Earth in the phase of decreasing axial tilt (in the interval from 3000 BC to 2999 AD) are determined. Changes in the annual specific irradiation energy and irradiation intensity have a similar character. There is an increase in irradiation in the equatorial region (a source of radiative heat) and a decrease in the polar regions (heat sink), that is, an increase in latitudinal contrast in the annual irradiation of the Earth. Changes in the semi-annual values of the specific energy of irradiation and the intensity of irradiation have a different character. There is a decrease in the specific energy of irradiation in the summer half-years and an increase in the winter half-years (seasonal differences for the specific energy of irradiation are smoothed out). For the intensity of exposure, a more complex pattern of change is noted, in which seasonal differences in the northern hemisphere smooth out more intensively than in the southern hemisphere. It was determined that in the phase of decreasing the angle of inclination, the area of the areas located beyond the polar circles decreases by approximately 25.93 %, the areas located between the tropics and the corresponding polar circles increase by 12.87 %, the areas located between the tropics and the equator in the phase of decreasing the angle of inclination decreases by 9.80 %.
