You can’t just eyeball these graphs and assume the trend is linear: https://tamino.wordpress.com/2019/10/09/sea-level-accelerati...

I hope you'll forgive the reader for interpreting this as them positing that the trend is linear.
> Although the trend may vary with the end year, there is no statistically significant difference between the calculated trends if their 95% confidence intervals overlap. Therefore, the most recent calculated trend is not necessarily more accurate than the previous trends; it is merely a little more precise. If several recent years have anomalously high or low water levels, the values may actually move slightly away from the true long-term linear trend.
