In this article scientometric analysis of the data on the number of publications on six environmental issues is conducted. The following methods of analysis were applied: the method of linear interpolation, ssa method and correlation analysis. An analytical expression to describe the changes in the number of publications over time was found by the method of linear interpolation. The degree of the data “pollution” was analyzed by SSA method. The rate of change in the number of publications in a given time interval is analyzed in details. The substantial significance of external factors on the initial number and dynamics of the publications growth is shown.
