There are many tens of thousands of observations of
sea -

Although the calculations of 18 - year rates of GMSL rise based on the different reconstruction methods disagree by as much as 2 mm mm yr - 1 before 1950 and on details of the variability (Figure 3.14), all do indicate 18 - year
trends that were significantly higher than the 20th century average at certain times (1920 — 1950, 1990 — present) and lower at other periods (1910 — 1920, 1955 — 1980), likely related to multidecadal variability.The IPCC AR5 found that it is likely that a
