Brief Comment by Kip Hansen
Have you ever noticed that whenever NASA or NOAA presents a graph of satellite-era Global Mean Sea Level rise, there are no error bars? There are no Confidence Intervals? There is no Uncertainty Range? In a previous essay on SLR, I annotated the graph at the left to show that while tide gauge-based SLR data had (way-too-small) error bars, satellite-based global mean sea level was [sarcastically] “errorless” — meaning only that it shows no indication of uncertainty.
Here’s what I mean, this is the most current version of satellite Global Mean SLR from NOAA:
This version of the graph does not have the seasonal signals removed [meaning it is less processed], shows the satellite mission that produced the data, and rather interestingly shows that, as of yesterday, satellite-derived Global Mean SLR has slowed to 2.8 ± 0.4 mm/year. NOAA NESDIS STAR has been…
