  1. This map shows how much the ground is expected to sink over 50 years.

    **Keep in mind that a large part of the Netherlands is already below sea level.** [See dark blue areas in this image](http://www.pbl.nl/sites/default/files/cms/afbeeldingen/nap_dijkringen_72dpi.jpg) and [this detailed map indicating that some parts lie more than 5 metres under sea level.](http://avn.geo.uu.nl/15water/40/40.jpg) Further subsidence will only enlarge this difference with respect to sea level. This does not even include the effect of the rising sea level.

    The ground level sinking in the west is due to groundwater-related subsidence and due to the fact that reclaimed land has the tendency to sink over time. The vast orange blob in the north east (province of Groningen) indicates subsidence due to the extraction of natural gas. Normally, the gas pressure in the reservoirs also supports the soil layers above the field. If the pressure drops after extraction, the overburden pressure increases and this may lead to subsidence at the ground level. Since exploitation of the gas field started in the late 1960s, the ground level over a 250 km² area has dropped by a current maximum of 30 cm. [Read more](https://en.wikipedia.org/wiki/Subsidence)

  2. My area jumps from sea if we look at geological timeline, few mm/year anyways. I feel bad to win this one.
    Maybe finns should make “always 2nd” area and move itävaltalaiset there 🙂

  3. This mysterious land can only exist in Europe because we don’t have hurricanes, tropical storms or tsunamis, unlike many other populous coastal regions in the world. The Netherlands would be a massive basin for the flooding that such events would bring.

  4. Oh climate change is no big deal. /s
    When you are land under in the netherlands just come over to germany. We need more polite people here anyway, and more wheat and gouda. Bring this, too.
