Norfolk’s geological record tells a story of climate change.
Between 2.5 million and 900 000 years ago the coastline was much further inland than present day, but in many ways the environment and climate was quite similar.
Since then Norfolk has experienced cold stages, when the landscape was covered with glacier ice and the climate would probably have resembled that of present-day Iceland.
It has also experienced warm stages, when temperatures were much warmer than the present day, and the region resembled the ‘Costa del Cromer’!
These climatic changes had a large effect on the region's landscape and geography, and the position of the coastline.
