“no long-term acceleration of sea level has been identified using 20th-century data alone.”
“It is likely that GMSL [Global Mean Sea Level] rose between 1920 and 1950 at a rate comparable to that observed between 1993 and 2010”
The instantaneous rate of interannual variability of (a) the GMSL, (b) the global mean steric sea level, and (c) the global mean ocean mass, i.e. the first-order time derivative of third IMFs shown in Fig. 1.
a. Regression of total sea level (observed by altimeters) during 1993-2012 on the third IMF of the GMSL given in Fig. 1a.
b. Same as Fig. 3a but for the steric sea level.
a. The intrinsic trend of the GMSL, i.e. the first-order time-derivative of the trend function of the GMSL given in Fig. 1a. Thick solid black line denotes the mean intrinsic trend of all the sub-samples of the GMSL during 1993-2012. Thin solid black line gives the linear trend of the GMSL rise, and the thin dashed lines give its one standard deviation.
b. Same as Fig. 4a but for the intrinsic trend of the global mean steric sea level.
c. Same as Fig. 4a but for the intrinsic trend of the global mean ocean mass during 2003-2012.
a. Mean trend of the total sea level rise during (top) Period 1 (1993-2003) and (bottom) Period 2 (2004-2012).
b. Same as Fig. 5a but for the steric sea level.
