Rocky coasts are also in danger of disappearing due to climate change

Not only sandy beaches are affected: the rise in sea level as a result of the global rise in temperature threatens to accelerate the erosion of rocky coasts dramatically. This is the result of a study by Imperial College London. According to this, rocky coasts could recede by the year 2100 at up to ten times the rate of previous erosion – depending on how much global warming progresses.

Up to 22 meters less coast by 2100

According to the calculations, in two sections of the British coast this will probably lead to the rock formations receding by at least 10 to 22 meters in 2100 – with dramatic consequences for people and infrastructure. ‘Coastals around the world are home to hundreds of millions of people and hundreds of billions of dollars worth of infrastructure such as housing, businesses, nuclear power plants, transport links and agriculture,’ the British researchers said. There has not been a comparable erosion of rocky coasts for 3,000 to 5,000 years. Rocky coasts account for more than half of the coastline worldwide.

According to the scientists, the study is one of the first to deal with the decline of rocky coastal sections. So far, the consequences on sandy coasts have been investigated.
