Rising Seas Will Erase More Cities

Land projected to be below tideline in 2050

Improved elevation data indicate far greater global threats from sea level rise and coastal flooding than previously thought.

Much of Ho Chi Minh City, the nation’s economic center, would disappear with it, according to the research, which was produced by Climate Central, a science organization based in New Jersey, and published in the journal Nature Communications.

Looking at portins of the UK below, you can see the projected land mass that will be under water at high tide.

To see how bad rising tides have become, switch between the Legacy data and CostalDEM whilst viewing the map.


Read the related report: FLOODED FUTURE:Global vulnerability to sea level rise worse than previously understood whose EXECUTIVE SUMMARY states:

• As a result of heat-trapping pollution from human activities, rising sea levels could within three decades push chronic floods higher than land currently home to 300 million people

• By 2100, areas now home to 200 million people could fall permanently below the high tide line

• The new figures are the result of an improved global elevation dataset produced by Climate Central using machine learning, and revealing that coastal elevations are significantly lower than previously understood across wide areas

• The threat is concentrated in coastal Asia and could have profound economic and political consequences within the lifetimes of people alive today
