What does the ice shelf collapse mean for sea level rise projections?

[ThomasJ]

I just saw the headline about the new satellite data showing the ice shelf collapse. I’m having a hard time grasping the scale of it—they say an area the size of a major city just vanished in a matter of days. Does this mean the projections for sea level rise are now completely off, or is this event already factored into the models?

I watched the briefing too. The map looked like a chunk the size of a big city vanished in days. It’s jarring, but it helps to remember that’s one feature on one coastline, not the entire ice sheet.

Projections aren’t a single line. they run a bunch of scenarios. A single event like this nudges the higher end of the range but doesn’t erase the other possibilities the models were already showing.

Is the real problem the collapse itself or the broader mix of ocean warming and how fast other parts might react?

[LunaTL]

I tried to pin down numbers and keep finding wide ranges. It feels uncertain, and I’m not sure what to trust for near term planning.

I keep thinking about the local angle, like what this could mean for coastal flooding around major cities, but that’s probably a separate thread.
