Expert on the Dutch sea level rise in 7 stages!

On Monday 20 June 2022, more than 1000 sustainable cyclists will cycle almost 400 kilometres. A journey along the coastline that is created in the Netherlands when the sea level rises too far. A coastline that, as far as Cycling 4 Climate is concerned, may never become reality. But what exactly is the problem with rising sea levels? And what causes it? We answer these questions ".Understanding in 7 stages how and why the Dutch sea level is rising!".

The1st stage:

Climate warming caused by increased greenhouse gas emissions will inevitably lead to a rise in global sea levels. How this will affect the sea level in the North Sea is complicated because more processes are involved than in the open ocean.

Expansion of ocean water

The global sea level is currently rising by about 4 millimetres per year. This is not only because the quantity of seawater is increasing due to melting land ice, but also because the seawater is warming up and expanding. The latter effect is not equally strong everywhere and the related sea level rise is therefore not equally great everywhere. For example, in a kilometre-deep ocean the effect of warming is potentially much greater than in the shallow North Sea, as there is more water that can expand. 1]

Melting Antarctica

In the Netherlands, future sea level rise will probably be just above the global average. This increased rise is due to the fact that the melting of Antarctica has 100 to 120 % more effect on the Dutch sea level rise than the global average. Exactly how this works will be discussed in detail in the second part of this section.

Melting Greenland

On the other hand, the contribution of Greenland's melting is less here in the Netherlands, because we are relatively close to the melting ice cap. A large ice mass like Greenland's raises sea levels locally. As this ice mass loses mass, its attraction to the nearby oceans decreases. Locally - up to a distance of 2500 kilometres from the Greenland ice sheet - this decrease leads to a drop in the sea level. Further away from the ice cap, however, the sea level will rise even more. The Netherlands is at a distance of 3200 km from Greenland, where the contribution is still relatively small, about 20 to 30 percent of the global average. [2]


What does this mean for the Netherlands in the future? How long do we have before it becomes disastrous? And what is currently being done to counter this effect? We will deal with that in the next stages of this section!

  1. I am enormously concerned about the future. It seems to me that humanity has gone too far in being unboundedly taken with itself. This has created an ever-increasing alienation between man and nature. Nature our mother and protector is now considered a source of enrichment for far developed countries and some specific multi-millionaire, selfish figures among us. I am Brazilian, born and raised there and it hurts with enormous pain to see how mountains rich in important mineral ores are being torn down until they disappear and in their place a deep hole is left in the ground. The ores are used to quench the appetite for luxury, well-being and wealth of the few; eternal old trees are cut down in Mata Atlantica the stretch of primeval forest, which runs from Atlantic Ocean to the west to the Pacific Ocean and in the primeval forest: the Amazonas.
    The violence against nature is so great that the trees are toppled by tractors, armed with thick chains, driving parallel into the forest. The logs (hardwood) are sold to distant rich countries, the waste that remains is burned and the empty space is sold to unscrupulous farmers to grow soy or maintain 'pecuaria' cattle. Cattle for export action to rich countries. The result is that the major rivers dry up, in mass the fish, crocodiles and other aquatic animals die. Appen, jaguars, 'antas', anteaters, snakes, all kinds of insects and even birds that don't want to leave their nests, like parrots and 'araras' are being burned alive.
    People who live in the north, above the Equator, and do not know the primeval forest, and cannot make their own representation of it, think that nature recovers itself. But... how do recover if some plant or animal species disappeared in its totality?
    In the same way, mankind acts towards the Oceans, and their indispensable fauna and flora.
    Nature is not to serve man! We humans are otherwise part of nature and must learn to live in a concerned complicity with the laws of Mother Earth, or else, we choose to totally ruin our race and all other life on our planet.
    The climate crisis we caused, or will we recognize that and work hard to restore nature and on land and water, or will our children have to pay for it. I'm afraid that's the way it is not otherwise....
