Whenever glaciation resumes the effect will be much lower sea levels. This may not happen for a 1,000 years or more. What they are saying in this article is that sea levels may rise before then. OK. We will have to deal with it if it happens.
This means we will have to adapt to rising or falling sea levels. Our efforts should focus on how to adapt rather than some ridiculous idea that we can control the climate at this stage which we can’t.

“During the peak of the last glacial cycle (around 20,000 years ago), global sea levels were approximately 400 to 425 feet (122 to 130 meters) lower than today.
This was because a large amount of Earth’s water was locked up in massive continental ice sheets.
Consequently, many areas now underwater were dry land, such as the Bering Land Bridge connecting Asia and North America. “
There are old Roman Era docks in western Europe made of concrete (they invented it) that are several meters under water, so only 2000 years or so we had some major ice sheets still covering parts of the northern part of the globe..............
