After discussion with @anoukvlug, it seems that correcting by default the climate bias and variability with the baseline climate data (up to date, it's CRU databse) is important otherwise general users will not do this kind of correction despite its importance (Vlug et al., 2019, Zekollari et al., 2019).
However, it appears also important to document it, not only in the function itself, but also in the enhancements section and/or in the FAQ (both are in the documentation web site), in order to avoid miss interpretation about the quality of the climate model projections of the temperature / precipitation evolution.
I also think that we need to keep in mind that we do not know the variabiliy evolution of atmospherical variables in the future.
