Default climate effects function in the case where no climate effect is simulated
additional arguments that are passed to LandR.CS
speciesCode, as well as
growthPred columns with % reduction/increase of mortality and
growth biomasses resulting from a climate effect.
These percentages are later multiplied by the by baseline biomasses of mortality and growth
(e.g. 0% meaning total mortality or growth reduction, and 100% meaning no reduction).
This default, no climate effect, function outputs 100% for all cohorts for both
