![]() All three are proving extremely difficult to achieve in places where hitherto the environment has been assumed to be more or less stable. 2Īdapting to rising sea levels involves three general strategies, that is, 1) the construction of defensive structures, 2) so called 'nature based strategies' - a combination of preserving and reconstructing coastal landscapes so they buffer and absorb rising waters, and finally 3) gradual retreat from the coastline. In Europe, a lot of big and famous cities would go the. National Geographic created interactive maps that show how would world coastlines look like if all the polar ice caps melt. Even if sea level rises only 0.74 meters by 2100 as is conservatively predicted some 115 million people will likely be displaced and 420,000 km 2 of land will be lost to the encroaching seas. If all the ice on land has melted and drained into the sea, the sea level would rise 216 feet (66 meters) and create new shorelines for our continents and inland seas. 1 In this scenario, vast new coastlines and inland seas will be created and 50 of the world's major cities would become architectural reefs. This map shows the land which would be flooded if the ice caps melt in entirety, in which case the sea level would rise by 80.32 meters. If we keep burning fossil fuels indefinitely, global warming will eventually melt all the ice at the poles and on mountaintops, raising sea level by 216. The difference now is that we are both causal to and threatened by the changes taking place. This visualization is a collection of maps, by continent, that project the impact on coastlines of a 216-foot rise in sea level, which. Inversely, in warmer periods the oceans have been anywhere between 6 to 30 meters higher than where they are currently. Sea level is now 120 meters higher than it was 20,000 years ago a world of more ice and land bridges unrecognizable to us now. ![]() The climate has always been changing and the oceans have risen and fallen accordingly.
