GMSL Rates
CU: 3.1 ± 0.4 mm/yr
AVISO: 3.2 ± 0.6 mm/yr
CSIRO: 3.1 ± 0.4 mm/yr
NOAA: 3.2 ± 0.4 mm/yr (w/ GIA)
Frequent Questions
Is sedimentation in the oceans accounted for in the GMSL estimate?
What determines the x-intercept (i.e., "zero-crossing" or "base year") of the GMSL plots?
Why is the GMSL different than local tide gauge measurements?
What is the definition of global mean sea level (GMSL) and its rate?
What is glacial isostatic adjustment (GIA), and why do you correct for it?
