Climate change has led to storms becoming more extreme and rising sea levels, threatening the future of coastal communities around the UK.
The British Geological Survey suggests up to 1.35 million homes could be at risk by the end of the century without further sea defences.
On this week's ClimateCast with Tom Heap, the team are on the Isle of Wight and in north Norfolk hearing from people who are losing their homes to the sea and from others fighting to protect their properties.
Tom also speaks to those who make the decisions on what should and shouldn't be saved from the sea.
