Looking at the graph there it appears the slope from 2010 onwards is steeper than before 2010 but I'd have to look at the raw data to check. Edit: It's clearer

Looking at the graph there it appears the slope from 2010 onwards is steeper than before 2010 but I'd have to look at the raw data to check.
Edit: It's clearer on the second graph below. From 1870 to present it looks very much like an exponential growth curve, particularly the last few decades.
- gus_massa 7y agoThe second graph is evidently curved, but it can be fitted quite good by a parabola. Crappy fit: https://imgur.com/a/ViBR21p https://imgur.com/a/ViBR21p Why do you think it is an exponential function?
- dwaltrip 7y agoExponential or parabolic, the rise is still accelerating. The second derivate of sea level is positive in either case.
- gus_massa 7y agoYep, like .2 mm/y^2. Exponentials grow much faster than parabolas. When you see that an exponential changes from almost 0 to something, it will change from something to too big to fit in the graph soon, really soon. Parabolas grow more smoothly. The difference is important to make some realistic predictions.
