UK Isostatic sea level rise

Question 1

Why is isostatic sea level change occurring in the UK?

Answer 1

Glacial Rebound in Scotland from the last glacial period is causing the NW to rise and the SE to fall, resulting in sea level change.

Question 2

UK Ria Example:

Answer 2

Poole Harbour in Dorset is a Ria (drowned river valley) formed at the end of the last ice age due to isostatic and Eustatic sea level rise.

Question 3

How is London at risk?

Answer 3

Isostatic and Eustatic sea level rise risks flooding and large tidal changes up the Thames.

Question 4

How much have sea levels risen?

Answer 4

Sea levels have risen by around 16.5cm since 1900, but the Met Office says the rate of rise is increasing.
They are now rising by 3-5.2mm a year, which is more than double the rate of increase in the early part of last century.
