In the report the results of statistical analysis of the mean monthly and annual air temperature series in Poland in the period 1951-2000 have been presented. The calculated means have been based on data from 51 weather stations located at the altitude below 1000 m above the sea level. The mean of the year 2000 was a maximum value of all since 1951 and probably since the end of 18th century. The analysis of order of appearance of rising values using the method of rank trend of Mann--Kendall, has proved an essential positive trend of average annual, March and May temperature values in the period of 1951-2000. This effect has been confirmed by a simple linear trend analysis. The rise of annual mean in 50-year period has been estimated as 0,9 centigrade. The highest May, August and annual average values of temperatures in the period of 1981-2000 proved to be higher than in the period of 1951-2000. In the long-term time series of 1951-2000 a shorter 7-8 year period oscillations around average has been found. In the 80s. and 90s. the significant rise in the mean annual air temperature occurred. Some reasons of climate warming have been discussed including intensification of zonal circulation and rise of insolation in the end of studied 50-year period. The coincidence of climate warming in Poland with global temperature rise has been also stressed
