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?
