That's a questionable comparison since we don't have reliable data from before 1993.
If the actual sea level rise was 3mm/year recently, we should surely not expect it to rise 25mm/year on average for the next 80 years?
- simonh 7y agoYep the historical data is an estimate. I don’t understand your last point. A 2m rise by 2100 isn’t the prediction of the article, it’s more likely under a metre. 2m is the 95th percentile outlier or something. Even so, if carbon emissions are continuing, the rate of warming will increase. Also I’d expect to see a hysteresis effect, where the effects of warming lag the cause so it wouldn’t be surprising to me to see an acceleration of its consequences. Finally, if the rate of sea level rise could up to triple in a few decades, why couldn’t it triple again? And again? I just don’t see the basis of your argument.
