In 2015, the Norwegian Centre for Climate Services launched a national report about the past, present and future climate, “Climate in Norway 2100”. This report gives a thorough understanding of the Norwegian climate, the possible future, and effects on storm surges, floods, avalanches and landslides. The information is too comprehensive for climate change adaptation measures in the municipalities. Therefore, in parallel with the production of the national report, a small project was carried out led by the county of Troms involving selected municipalities, the county authority, the Norwegian Centre for Climate Services and the Norwegian Directorate for Civil Protection.
The focus was on the officers in the municipalities responsible for land use planning and their needs for tailored information about climate, climate change and natural hazards. The result was an eight pages county level climate factsheet with highly condensed information. As the white paper on climate change adaptation in Norway states that adaptation measures should use the precautionary principle, RCP8.5 is the chosen emission scenario used as a basis for the factsheets. Climate factsheets have now been developed in collaboration with users from the counties and municipalities for all counties in Norway, seventeen in total. The factsheets have a clear structure:
- Introduction where the most serious climate risks for the county are presented
- Description of the expected future climate, i.e. temperature, precipitation and wind
- Effects on hydrology including floods
- Effects on avalanches and landslides
- Sea-level rise and storm surges
- Urban flooding
The factsheets have become popular, and are now better known than the Norwegian Centre for Climate Services. Multiple government organizations distribute the factsheets and recommend them as a basis for integrating climate change adaptation in various planning processes in the municipalities. The factsheets are also referred to as the basis for climate change adaptation in a new governmental planning instruction on climate adaptation.
