So between Greenland and Antarctica, in the last 10 years, they were contributing about 1.5mm of sea level rise per year.

NASA says we are averaging 3.3mm per year: https://climate.nasa.gov/vital-signs/sea-level/

I wonder what contributes to the other 1.8mm.

Interestingly, you don't see a significant slope change around 2002-3 where this Greenland tipping point was found in the satellite data, but the ground data does look like there is an inflection around 2000.

Thermal expansion!

    Sea level has been rising at around one-eighth of an inch (3 millimeters) per year on average since 1993, with about half of that caused by the ocean expanding as it's heated, and the other half due to additional water added to the ocean, mostly from melting continental ice.
