North Sea Level rise
I have always had the idea, that past years the level of the North Sea has risen very rapidly. This is what the main stream media tries to make us aware of. Some meters rise coming years would be possible they say.
However, lately I bumped into this article:
https://klimaatgek.nl/wordpress/2021/01/17/de-zeespiegel-in-nederland-1901-t-m-2019/#more-7043
I found that the last 100 years the North Sea level rise is
lineair and does not show a grow acceleration. The absolute North Sea level
rise is appr. 15 centimeters in a century
(100 years).
This graph shows the average height of 6 sea costal
stations in The Netherlands.
In spite of this (only) 15 cm rise per century, I am not underestimating the forces of water and wind. I have a special interest in the sea level rise because I live on Goeree-Overflakkee. This island was struck by the ‘Watersnoodramp’ (North Sea flood) that took place in the night of 31 January/ 1 February 1953.
A combination of a high spring tide and a severe windstorm
over the North Sea caused a storm tide. Dykes broke and the sea flooded up to
about 6 meters above the mean sea level.
Today, this happened exactly 68 years ago. During this disaster 1836 people in Zeeland, Brabant and Zuid-Holland were killed. Also on the island where I live (Goeree-Overflakkee) more than 300 people lost their lives (Oude Tonge).
Today, many people in the neighbourhood commemorate the flood
and its victims.
Interesting story for radio amateurs: About 20 km from where
I live, in Zierikzee (capital city of Schouwen Duiveland), Peter Hossfelt jr. –working
in a radio store/shop - managed to make a 80 mtr band transmitter to inform the rest
of Holland about the disaster that had taken place. A replica of this
transmitter can nowadays be found in the ‘ Watersnoodmuseum’ in Ouwerkerk.
