melting icebergs don't rise sea level. Water is denser than ice, even if the iceberg melts, water just fills previously occupied space

Unless the ice rest on land, like in Antarctica, which the article points out.

Definition of an iceberg: noun - a large floating mass of ice detached from a glacier or ice sheet and carried out to sea.

If it rests on land, it's not an iceberg, is it?

Northern Europe: (Likely) neutral to negative, due to land rise (from the latest ice age).

But the uplift is a lot slower than sea rise, yes ?

In most of Sweden (except the very south) the uplift is faster than the current projected sea rise.

But it can't be so for the long term, can it?, if projected sea rise is like over ten meters.

As an example: 10k years ago during the last major ice age, Stockholm was 150 meters below the current sea level. The land is springy...

In 2009 a dock needed to lowered by 0.5 meters to keep up with the land rise.

AFAIK there's not the same phenomena in Helsinki. Is it so much less springy across the gulf ?

Seems odd...
