A change to sea level is expected as our climate changes. This will happen because:
Flooding at the car park in Lower Town, Fishguard.
Most people think that melting ice is the most important cause of sea level rise, but this is not true. It is the expansion of the sea water as it gets warmer that is causing the biggest change to sea levels.
According to the UK Government's UK Climate Change Risk Assessment 2017, sea levels in the UK are rising by approximately 3mm a year.
What might happen if sea level rises?
Most of us don't think that sea level rise will affect us much, but is that true?
Think of the land between Penally and Tenby. Much of it is low-lying, and just above sea level. If sea level rises the dunes will disappear, the sea will flood the coastal road and the railway line from Tenby to Pembroke.
The estuaries are also places where people keep their boats. Imagine the pill at Neyland or the harbour at Pembroke Dock. How will they change?
High spring and autumn tides affect places such as Angle and Fishguard on the coast, but also reach far up the Daugleddau Estuary to flood Carew and even Haverfordwest.
