World with a 100 meters sea level rise
The global sea-level rise started around the beginning of the 20th century. From 1900 to 2016, the average sea level on the planet rose by 16–21 centimeters or 6.3–8.3 inches.
According to the extreme scenario, an increase in sea level can be presumed as 189 centimeters (6.2 feet) by 2100. Maldives or Tuvalu and other low-lying island nations are among the territories at the highest level of danger. At current rates, the sea level would be high enough to make the Maldives unlivable by 2100.
The maps below show how our planet will change if all the ice on the land melts and drains into the sea.

The coastal populations most at risk are those occupying low lying land. People in these areas will have no choice but to migrate further inland.
One reason for forced migration is that rising sea levels will result in the loss of agricultural lands due to permanent submersion or frequent flooding, causing the water table’s salinity and making the soil unproductive.
Economically, GDP per capita is generally above average for coastal populations and cities [Dasgupta et al., 2007]. That coastal areas are critical to international trade and commerce in today’s globalized economy, significant disruptions to important port cities would have widespread ramifications. Alongside port infrastructure, inland infrastructures such as roads, railways, and airports in low-lying regions are vulnerable to loss or damage [US EPA,2009]. Other industries important to GDP, in particular travel and tourism, would also be severely affected.
Rise sea level will necessarily have an impact on biodiversity, potentially leading to loss. Many species are specially adapted for a particular type of coastal habitat and maybe threatened if this habitat is affected by erosion, increased salinity, loss of wetlands, mangroves, tidal marshes, more frequent flooding, etc
I love old maps. I have a map alleged to be millions of years ago carved in rock…
Why on Earth should Sweden give away territory to Denmark?
The parts of Sweden that you call new Denmark have never, ever been Danish. For all I care, they can drown if they don’t want to emmigrate.
Kehehe
I like how fired up that got you~
100 meters! Absurd.
Agreed. Even if Earth’s surface ice melted entirely, that would only cause a rise of 70m. Without any ice left to melt, where would the other 30m come from?
Water expands when heated. Basic physics 101
Aren’t we confusing issues here? What do changes in countries’ boundaries have to do with sea level rise?
The first is a wild ass guess, and the second is a ludicrous worst case scenario.
Directly, nothing. Indirectly…some countries will have difficulty accessing land that is no long contiguous. Others will have difficulty mustering military defenses against proximate aggressive neighbors. The scenario here is exaggerated, but there is still merit in its position. Not all of these changes are possible. Some of the possible changes are unlikely, but…America already has experts making contingency plans for these sorts of changes on the instructions of the Department of Defense. It’s a safe guess that at least some other countries’ governments are making similar plans.
