Frequent Questions

  • Is sedimentation in the oceans accounted for in the GMSL estimate?
  • Can I subscribe to the mean sea level estimates?
  • What determines the x-intercept (i.e., "zero-crossing" or "base year") of the GMSL plots?
  • Do you account for plate tectonics in the global mean sea level trend?
  • What is the definition of global mean sea level (GMSL) and its rate?
