What would be the sea level rise if all fossil fuel resources are burned? Tokarska et al. (2016), a Nature article from a team of the University of Victoria, predicted a global temperature increase of 7&plusmn;2.5°C and 17.2&plusmn;2.5°C at the equator and at the poles respectively if all proven fossil carbon resources are burned (about 5 trillion tons of carbon).  

What would be the sea level rise with this temperature?
At the upper end of that range, all ice on Earth would melt.

That would ultimately give roughly 70 metre sea level rise from melting ice alone, but it may take thousands of years before it reaches equilibrium.

Add a bit to that to account for the thermal expansion of sea water.
