Global Sea Level Change
We compute the GMSL rate from altimetry data over five-year-long moving windows to show the interannual variance in the period 1993–2014 and depict the results in Fig. 4.1. The average trend from 1993 to 2014 is 3.2 ± 0.4 mm/yr. Rates faster/slower than the whole-period average are expressed in red/blue. Figure 4.1 shows that the GMSL rate was fast in 1996–2004 and slow in 2005–2010. Since then, the five-year trend appears to be accelerating again, indicating that the GMSL is rising faster since 2010.
