one wild card is the warming of the deep ocean suficient to cause the physical expansion of that water,driving sea level rise this is happening now,and is causing localised sea level rise,in the gulf of mexico something not fully accounted for is that the ice in the arctic is bieng formed from an increasingly fresh water top layer,it freezes fast.....and works as an insulative layer,locking in heat a more complicated source of heat is bieng generated in the greenland ice cap,where the surface melt water creates enough frictional heat as it falls through the miles of ice,to melteven more water,this is basic physics...as described by Mr Watt,james there are now enough positive inputs pushing sea level rise,that we now have multiple non zero chances at an ultra extream event,toggling the whole world ocean into different paterns the thing is that there are NO negative inputs and the full list of positive inputs is long,and all of those inputs are growing at an accelerating pace
