Which cities face floods due to ice melt?

The Indian city of Kakinada in Andhra Pradesh is also at a risk of getting flooded.

An ice sheet is a continental glacier that covers a large area.

The GFM tool shows how troubling the rise of sea-levels is.

Previous NASA research has said that if Antarctic ice in the western portion of the continent were to melt, the world's sea levels would rise four feet across the globe, but the Eastern Seaboard of the US would see rises of more than triple that estimate.

The tool provided a way for governments to work out which ice sheets they should be most anxious about.

Explaining the importance of the new tool, Erik Ivins, senior scientist at Nasa's Jet Propulsion Laboratory in the USA said, "As cities and countries attempt to build plans to mitigate flooding, they have to be thinking about 100 years in the future and they want to assess risk in the same way that insurance companies do".

Glaciers - that hold 75 per cent of world's freshwater - are melting at a brisk place due to global warming.

Earlier this month, a major climate report released by the Trump administration revealed that global average sea level has risen by about 7-8 inches since 1900, with nearly half of that rise coming in the last 25 years. The rate is not constant due to gravity, the "push-pull influence" of ice, the wobble of the planet. For instance, the study finds that for Antartica and Greenland, changes in the predictions of a flood at major port cities depend on the location of the drainage system.

Climate scientists have said for decades that human-caused global warming causes ice to melt that in turn will raise global sea levels, and in recent years scientists have made increasingly precise projections about how individual cities will be affected.

Similarly, the research showed that Sydney, Australia is most affected by the melting of the Antarctic ice sheet on the other side of the Antarctic continent from the eastern Australian city.

He said that city officials can follow observations for the glaciers and polar regions likely to have the most impact on their city and use that data to map projected sea level rise.
