Abstract

This work considers a series of numerical experiments to identify the direct role of the sea ice reduction process in forming climatic trends in the northern hemisphere. We used two more or less independent mechanisms of ice reduction. The first is traditionally associated with increasing the concentration of carbon dioxide in the atmosphere from the historic level of 360 ppm to the level corresponding to the maximum concentration in implementing the mildest scenario RCP 2.6 - 450 ppm. Due to this growth, the average air temperature in the Arctic increases, and, by this, the ice volume decreases. The second mechanism is associated with a decrease in the reflectivity of ice and snow. As a result, the amount of solar radiation absorbed by the ice increases while the ice volume decreases. We assume that comparing the results of these two experiments allows us to judge the direct role of ice reduction, regardless of the reasons that caused this reduction.
