considered in prospective climate change analysis, potential future changes of P and T
in particular months in time horizon 2070–2100 varied in the range 17–57 mm in the
case of the average monthly sum of precipitation, and from 1.2 up to 5.8
C in the case
of the average monthly air temperature. Lower and upper extreme projections derived
from the GCM-RCM’s analysed for each particular month were considered for the
purpose of this study as the boundaries of the projection’s uncertainty range
(Fig. 14.3a–d). In other words, the uncertainty range of prospective changes in P
and T in the Biebrza Valley can be considered as a most probable range of climate
change dimensions predicted with the analysed GCM-RCM and emission scenarios
combinations.
Among the GCM-RCM-emission scenarios ensembles analysed for the Biebrza
Valley, a general increase in average monthly air temperature is projected
(Fig. 15.3a). Throughout the whole prospective average year in 2070–2100, the
