I noticed you have measurements for all ice in gigatons. If all the ice melted in the next 100-1000 years, how much freshwater would be added to our oceans? How less salty would our oceans be? What would be the new approximate average freezing temperature of our oceans if all our ice melted? Would we have less freezing or more freezing in the bearing strait?
Is it possible that the Stonehenge Altar Stone (Stone 80) may not have been transported from northern Scotland by man, but by glacial transport, possibly to Wales?

Curious here,

Hello Kyle,
Thanks for your comment. there is information on this here: https://www.antarcticglaciers.org/glaciers-and-climate/estimating-glacier-contribution-to-sea-level-rise/
It takes ~361Gt to raise global sea levels by an average of 1 mm.
Observed Sea level varies regionally, see here: https://www.antarcticglaciers.org/glaciers-and-climate/sea-level-rise-2/recovering-from-an-ice-age/
