Sunday 6 March 2011 On Benbecula, they know all too well that rising tides threaten the UK’s coastline. For the 1,200 inhabitants of the small, low-lying island in the Outer Hebrides, the sea’s encroachment is becoming a serious problem, especially on its western shores. Impacts of Climate Change on Disadvantaged UK Coastal Communities, a report to be published tomorrow by the Joseph Rowntree Foundation, an influential thinktank, records how local people have seen the coastline retreat before their eyes in just a few years. The threat posed by erosion has been exacerbated by the fact that the sea has taken material from the island’s beaches that is normally used for constructing roads and buildings. But Benbecula is not alone: the report claims that rising sea levels are likely to have a “severe impact” on much of the UK’s coastline by 2080. The authors note that “the total rise in sea levels off the UK coast may exceed one metre, and could potentially reach two metres”. They warn that “the frequency of intense storm events is expected to increase and, along with the rise in sea level, to lead to more coastal flooding”. As a result, many of the 30 million people living near the UK’s coastline – which has 291 inhabited islands – will need to anticipate how climate change will affect them. “We haven’t devoted enough time to debating these issues,” said Jeremy Richardson, director of the engineering consultancy URS-Scott Wilson, who co-authored the report. “Because we’re talking about what happens in 2050 to 2080, people tend not to talk about this, but the coast is going to be at the forefront of these climate change impacts. We’re not just talking about flooding or drought, but also rising sea levels and an increase in storminess; it will affect a lot of towns, many of which are especially vulnerable because they are isolated geographically.” …
