In the analysis of the potential of applying models to estimate threat of heat waves in Poland up to the end of the 21stcentury, two discrepant climate change models: the MPI‑M‑REMO‑ECHAM5 and DMI‑HIRHAM5‑ARPEGE have been used. In this regard, the maximum air temperature was analysed. The accepted definition of a heat wave was 3 and 5 consecutivedays of temperatures ≥30°C. According to the more realistic ARPEGE model, after 2040, the number of 3 day heatwaves will rise by 370% and after 2070 – 460%. In Warsaw, the extent of possible mortality rates due to cardiovasculardisease in heat waves amounted to +134% in the period after 2070 according to the ARPEGE model.
