Preface Note on the status of this report This report supersedes the Phase 1 Interim Report. It updates the findings of the Interim Report to take account of the UKCP09 climate change projections. The symbol 09 has been used to indicate where the Interim Report findings have been modified to reflect the UKCP09 projections. Sections 2 and 3, and Appendix 11 of this report provide a detailed analysis of the implications of the UKCP09 projections for the study findings. These find that under UKCP09 and for Scotland, one variable – winter precipitation – is likely to be significantly different in terms of scale and spatial distribution, when compared to the relevant UKCIP02 projections.
