Climate change is expected to lead to a rise in sea level. Primarily this will be because as the sea gets warmer, in response to the warming climate, it will expand. Glacier and ice-cap melt will also add to the equation, which is expected to cause a rise in sea levels in the region of 50 cm across the globe in the next 100 years.

To make things worse in Norfolk, the South East of England is sinking. It is sinking as the land adjusts to the ice melt which happened in Scotland at the end of the last ice-age.

In a worst case scenario, these two factors could combine to produce a sea level rise in the Norfolk region of up to 80cm in the next 50 years. In the best case scenario, produced by UEA, there will still be a 22cm rise.
