[en] Paper deals with climate change in Estonia by main trends in mean air temperature. Three characteristics are given. In table 1 the ice-break (mean in northen Estonia) dates and standard deviation are presented for 33-34 year periods. The two last columns show the earliest and the latest date of ice-break in given period. In the table 2 the average air temperature of April-July in Tallinn is given in the same system. The time-series is reconstructed on observed air temperature combined with calculated from rye harvest dates air temperature. Table 3 presents mean winter (December-March) air temperature in Tallinn. In this case the average of periods before instrumental observations is estimated from break-off dates in Tallinn Port. The main conclusion is that general warming in this century is accelerating (author). 3 tabs
