Coastal areas, where land meets the ocean, are important for people and the environment. The erosion of coastal cliffs is a natural process, but human activity and the effects of climate change have major implications on the dynamics of coastal change. In Denmark, human activity has a big impact on the coast, while in Greenland, the impact is smaller but the region is affected by climate change, which is happening faster in the Arctic. Coastal cliffs are not well studied compared to other coastal areas. In Denmark and Greenland, it is hard to understand why cliffs are eroding. This study looks at the dynamics of cliff erosion in Denmark and Greenland and how climate change is affecting this process. It also looks at landslides, which are a common cause of cliff erosion in Denmark. In Greenland, cliff erosion is caused by waves and rainfall and is expected to increase in the future due to more rainfall, storms, and less sea ice. The study also tested a new technology to measure cliff erosion accurately and quickly.
