Ancient buildings in the UK, older than the pyramids in Egypt, are at risk of being threatened by the effects of climate change.
This is a warning of British experts issued on 10/10, in the context of rising sea levels, greater rainfall and extreme weather events are endangering archaeological relics with high prices. historic value in Scotland.
The Orkney Islands off the north coast of Scotland are home to more than 3,000 historic sites. Archaeologists found evidence of human habitation in the archipelago 8,500 years ago. Some buildings on the Orkney Islands date back to the Iron Age, Viking and Medieval times. However, about 1,000 relics on the coast are at risk of being threatened.
One of them is the South Howe Broch heritage dating back to the Iron Age on Rousay Island. Built between 600-400 AD, seawater has invaded most of the western part of this monument. Currently the wall of the monument is sinking into the sea. Highlands and Islands University Lecturer Julie Gibson warned that the monument would eventually disappear.
South Howe Broch , a few hundred meters to the north, is Midhowe Broch, also dating from the Iron Age. Although this monument is well preserved, it also faces many risks due to climate change.
A report assessing the risks posed by climate to monuments on the Orkney Islands, published by the Historic Environment Scotland (HES) in July, shows the possible impacts due to climate change. Climate change in these monuments is “severe” and “high” vulnerability.
According to HES, average rainfall and snow in Scotland have increased by 27% since the early 1960s of the last century. During the same period, winter precipitation and snow increased by more than 70% in parts of northern Scotland. Wetter weather increases the risk of water intrusion and damage to structures that make buildings vulnerable to collapse. Sea level rise and coastal erosion are also potential threats to monuments.
