'In the absence of adaptation, beaches, sand dunes and cliffs currently eroding will continue to do so under increasing sea level .' 'Coastal squeeze is expected to accelerate with a rising sea level.

'In the absence of adaptation measures, beaches and sand dunes currently affected by erosion will continue to be affected under increasing sea levels .'
