This report assesses which of Scotland’s nationally and internationally important rocks and landforms are most at risk from climate change. It develops a risk-based approach for assessing future impacts of climate change on groups of similar geological and geomorphological features.
The assessment uses a systematic approach combining current understanding of how climate change will affect Earth Science features, and knowledge of the characteristics of these features in Scotland. Of the 650 plus Earth Science features notified in Scotland’s SSSIs, the report concludes that when it comes to risk from climate change impacts:
• 73% are likely to be fairly robust (at ‘medium’ to ‘low’ risk)
• 17% could be at moderate (‘medium-high’) risk and
• 10% could be at ‘high’ risk
• increased erosion,
• coastal flooding,
• changes in rainfall and storminess,
• changes in vegetation cover,
• and reduced freezing of the ground in winter.
Though there are some ‘high’ risk rock and fossil-bearing features, the majority of features at risk are sediments and landforms created during the last Ice Age and those still actively forming today. This assessment is intended as a sound base from which to incorporate climate change planning for geoheritage features into climate change action plans, and could be adapted to be applicable internationally.
