This article introduces new agro-climatic regionalizations in Poland in terms of the temperature change scenario under the global warming conditions. The following scenario has been determined: temperature increase by 1-2ºC each month during the growing period (April-October) and at the same times no change in atmospheric precipitation. The years 1971-2000 were established to be the reference period. According to the simulations carried out by the authors the area of the temperate-warm and warm region types (for the years 1971-2000) was as follows: 62 and 0%. When the temperature increased by 1ºC the values were respectively: 75 and 22%, and subsequently, when temperature increased by 2ºC, the values were respectively: 5 and 94%. As far as the precipitation regions are concerned, the area of the humid, optimal humid and temperate-dry regions changed from 10, 70 to 20% during the period 1971-2000 to 9, 48 and 43% for temperature increase by 1ºC, and to 7, 26 and 67% for temperature increase by 2ºC.
