Climatic models are essentially based on the energy, received by Earth from the Sun. The article shows methodic derivation of equations that lead to the daily insolation, i. e. the quantity of energy that hits a given area of spherically-shaped earth surface at given geographical amplitude on a given day. Analytical approximations are proposed for the time variation of the tilt of the geographical axis with respect to elliptic and of the eccentricity of Earth's orbit. The relative quantity of energy is calculated for the period of Würm glace age (up to 160 thousand years in the past). A comparison with other calculations and measured climatic variations shows that the simple model reproduces well the main features of the climatic curve.
