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
