> Oh and roughly 65M of sea level rise as the planet shifts to a snow/ice-free mode.
Where is this new figure coming from? It seems about 60X what's being published elsewhere.

If all glaciers and ice sheets on Earth melted, sea levels would rise roughly 65–70 meters (about 210–230 feet). It’s worth noting that a full melt of Antarctica alone would take many thousands of years even under extreme warming scenarios, so this is more of a thought experiment than a near-term risk. Current projections for this century focus on partial contributions, with estimates ranging from roughly 0.3 to over 1 meter of rise by 2100 depending on emissions pathways.
That's been known for a long time - it just hasn't been considered a likely scenario. It's the rise we'd expect if all the ice on Greenland and Antarctica were to melt:
