What these ancient clues tell us about future global sea level rise: Rock samples taken from the Greenland ice sheet’s Prudhoe Dome show it completely melted in the past 10,000 years — and could vanish again amid climate change.

I think an ice free earth is inevitable at this point along with sea level rise of 65-70 meters. The real question will be whether we cook ourselves in this greenhouse gas oven after migrating inland. And how long we sit on our hands before we make some pretty drastic societal changes to prepare for those scenarios.
