PALEOTEMPERATURES OF THE EARTH′S SURFACE. 2. DETERMINATION OF THE MIDLATITUDE NEAR-SURFACE HEAT-CAPACITY OF THE EARTH

Two methods have been proposed for calculating the midlatitude near-surface heat-capacity of the Earth: 1) using the latitude variation of the Earth temperature, and 2) using the insolation of the Earth in the modern epoch and its variation with time. Using the obtained values of this heat capacity, profi les have been determined for the midlatitude paleotemperatures of the Earth in three extreme epochs in the past 50 thousand years, and the evolution of the paleotemperature in the past 200 thousand years has been calculated.
