climate scenarios for impact studies in the Netherlands update WB21

These scenarios described here are an update from the WB21 [1] scenarios. Originally formulated for
the NRP IRMA project, this document is also meant to serve as a guideline how to translate the
difference in global climate projections between the recently released IPCC Third Assessment Report
TAR [2] and the 1995 IPCC Second Assessment Report SAR [3] into the previously formulated
climate scenarios for impact studies in Europe and the Netherlands [1, 4-5].
