This has been averaging millions of measurements of satellite altimeter over oceans. That is considered more accurate than tidal gauges which are subject to local changes such subsidence near river mouths.
The 3 mm is a combination of land glacier melt and water thermal expansions. I have heard talks all over the map as to which factor is more dominant.
So 4-5 mm a year in the near future is not too off.
- poutine 7y agoI liked table 1 as a nice summary from a referenced paper in the above paper, found here: https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1002/2014EF000239 https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1002/2014... Their data suggests thermal expansion is the primary culprit.
