Frequent Questions

  • What determines the x-intercept (i.e., "zero-crossing" or "base year") of the GMSL plots?
  • Is sedimentation in the oceans accounted for in the GMSL estimate?
  • What is the format of the dates in the GMSL time series?
  • What is glacial isostatic adjustment (GIA), and why do you correct for it?
  • How often are the global mean sea level estimates updated?
