Secular Perturbations in the Elements of the Earth's Orbit and Astronomical Theory of Climate Variations (Vekovye Izmeneniya Elementov Orbity Zemli i Astronomicheskaya Teoriya Kolebanii Klimata)
Abstract
The present paper deals with the astronomical theory of climate variations. The tables of secular perturbations in the earth's orbital elements for 3,000,000 years time interval backward and 1,000,000 years time interval forward from the epoch 1950.0 are given. The secular course of the solar radiation (in canonical units) in the earth's latitude 65 degrees north and south is illustrated since 1950.0 and in the form of the diagrams for the past 30,000,000 years and the future 1,000,000 years, the equivalent latitudes being used instead of the radiation values in canonical units. The problem of temperature changes due to the variations in solar radiation arriving at the earth's surface is discussed, only the influence of celestial-mechanic factors on the sun's radiation being considered.
