Some of the UK's coastal towns and villages may have to move - or face falling into the sea.
That's the warning that will be issued by the head of Environmental Agency as rising sea levels and erosion threaten a number of the country's coastal areas.
Sir James Bevan will tell a flooding and coastal erosion conference that the “hardest of all inconvenient truths” is that “in the long term, climate change means that some of our communities – both in this country and around the world – cannot stay where they are”.
