Climate change is a significant threat to communities, natural sites and historic buildings. Many of our unique cultural heritage assets are already being threatened as a result of sea level rise, coastal erosion, storm surges, regular flooding, and extreme weather events.

Rising sea levels
Sea level rise in the 21st Century is likely to exceed rates observed between 1971 and 2010 and an increase in average global surface temperatures is most likely to increase the amount and severity of rainfall, especially in high latitude areas.

Increased rainfall
The biggest climate related pressure is extreme weather and increased rainfall. According to the Climate Change Committee (CCC) report on Scotland in 2016, annual rainfall has increased by 13% since 1970.

Landslides and flooding
The erosion of the volcanic rock below Edinburgh Castle also poses a safety risk to pedestrians, vehicles, and tourists.

Increased tourism
Increased tourism is a risk to all heritage sites and the management of numbers of people passing through the historic buildings and parks and pedestrian routes will have an impact on the historic fabric of the area. The demand for increased tourism facilities is having a negative impact in Edinburgh resulting in an increase in the amount of waste being produced at the World Heritage Site.

Increasing levels of precipitation
Increasing levels of precipitation will also have a negative effect on the stone masonry of Edinburgh. Most buildings are made from porous sandstones and increased wetting and drying increased the decay of these stones.
