It's not just about the melting of the ice. I mean, it is. Point 2 in this list is about an ice shelf that itself is mostly floating (so that melting in itself doesn't really contribute to sea level rise), but this shelf blocks a glacier on land, preventing a massive amount of land ice from sliding into the sea, and from what I understand, it sounds like once the shelf collapses, this glacier flowing into the sea could lead to quite rapid sea level rise. And that glacier is connected to other glaciers that could soon follow, leading to the collapse of all glaciers across West Antarctica, which would be quite serious.
And that shelf is already melting, and cracks are appearing. It's currently kept in place by an undersea mountain, but when it melts too much or breaks up, it could lose that grip, and things can start moving very quickly all of a sudden.
The fact that global temperatures are undeniably going up and are continuing to rise, isn't exactly helping with keeping all that ice in its place.
