Sea level rise is a key indicator of climate change. Yet there is still a significant amount of people who doubt the actual occurance of GMSL rise.
The GMSL is a 1-dimensional time series of globally averaged Sea Surface Height Anomalies (SSHA) from TOPEX/Poseidon, Jason-1, OSTM/Jason-2 and Jason-3. All biases and cross-calibrations have been applied to the data so SSHA are consistent between satellites. Data are reported as changes relative to January 1, 1993 and are 2-month averages. Glacial Isostatic Adjustment (GIA) has been applied. (https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/2017JC013090)
