Why is sea level rising?

Sea level rise                                             Relative sea level rise

Melting ice caps put more water in the sea and raise sea levels by 1.7 cm a year

But on top of that, in the Netherlands, at 0.2 mm per year, it is also falling...

Three reasons why NL is falling

1. Peat

2. Ice ages effects

3. Mining of minerals

Peat

Accumulation of plant material

Soil subsidence in the peat polder

Measures the Netherlands can do are:

1) Dike improvement

2) Sand suppletion
