Reply to comment by CrustalTrudger in Why does the elevation of Greenland sink to near or below sea level in the center? by ILikePenguinss

Huh, so no help on sea level rise expected from this. I wondered.

Well here’s hoping scientists underestimated the short term impact an unprecedented amount of ice sliding into the ocean over a short period has on crust deflection and we get a fast enough rebound to reduce the impact of sea level rise (without, you know, massive earthquakes and the like)

Depends where you live. Overall, no. If you live in the PNW, then the land is rising enough to offset a significant portion of sea level rise.

With respect to GIA in the areas with extant ice sheets, there have been arguments that it could slow ice mass loss in certain areas (e.g., Vaughah et al., 2006, Zeitz et al., 2022), but broadly, these are pretty complicated dynamics with a lot of uncertainty in terms of how they'll actually play out.
