Even on the little thumbnail of that graph, I can see the curvature. Do you understand what that is? That's acceleration.

If the rate had not accelerated since that 1900-1930 rate, the total 2015 anomaly on this graph would be 69mm, not 176
If the rate simply stays at 4.4mm/yr, sea level rise anomaly by the year 2100 on this graph will be 550mm. But it's not. If it keeps accelerating as it has since 1900, by 2100 it will be just below 8mm/yr and the sea level anomaly on this graph will be 718mm. Now that assumes no massive ice collapses that could raise sea levels by feet essentially overnight.
