Historically the sea level given by models after past ice ages has tended to be too low and thus it was thought by some researchers that some component was missing from the models.
It seems this possibly could have been identified as being seawater intrusion into the ice causing cavities which then expand causing a feedback loop increasing the speed and volume of the melting:

“[Seawater intrusion] could basically be the missing piece,” said Dr Alexander Bradley of the British Antarctic Survey, who led the research. “We don’t really have many other good ideas. And there’s a lot of evidence that when you do include it, the amount of sea level rise the models predict could be much, much higher.”
Previous research has shown that seawater intrusion could double the rate of ice loss from some Antarctic ice shelves. There is also real-world evidence that seawater intrusion is causing melting today, including satellite data that shows drops in the height of ice sheets near grounding zones.
It's quite possible that all the horrible looking maps showing the expected coastlines in 2100 are actually too conservative.

Hmmm, maybe time to invest in a little beach front property in Peterborough. |  | | |

.... 'thus it was thought by some researchers that some component was missing from the models'
At a guess was the missing component an empty fairy liquid bottle or maybe some sticky back plastic ? |  | | |

That article links to this very good article https://www.theguardian.com/environment/2022/sep/08/world-on-brink-five-climate- which is a very handy read for anyone who doesn't know what tipping points means or which ones we are the most immediate danger from.
That excellent information like this is available, and yet the catastrophic environmental issues we face, and how we need to make positive and radical changes to win through, are not at the very front of everybody's minds (let alone in a General Election) I personally find bewildering. |  |
