They say if the whole thing melts, it's 24 feet of rising waters worldwide. But they don't project the odds of the whole thing melting, and don't share what they sense will melt at current rates.
In 1970, The Boston Globe ran the headline, "Scientist predicts a new ice age by 21st century." The Washington Post, for its part, published a Columbia University scientist's claim that the world could be "as little as 50 or 60 years away from a disastrous new ice age."

> Almost all land ice (∼99.5 %) is locked in theice sheets, with a volume in sea-level equivalent (SLE) termsof 7.4 m for Greenland and 58.3 m for Antarctica. It has beenestimated that approximately 25 % to 30 % of the total landice contribution to sea-level rise over the last decade camefrom the Greenland ice sheet
7.4 m corresponds to 24 feet so their claims are accurate.
Also, 58.3 m.... that's shocking. Predicted sea level rise until the end of this century is well below that but imagine the massive effort needed to deploy 69 m tall walls at our coastlines... scary as hell. Likely we'll just give up a lot of land.
