If you look back in time at various stable states of the Earth, and make the crude first-order assumption and connect the dots to make a line, it shows we could be in for around 50 metres of sea level rise, after the Earth system has done stabilising to a doubling of atmospheric Carbon Dioxide levels.

That, at least, should make you sit bolt upright in your chair and stop snoozing.
