This discovery creates further issues with climate models describing accelerating sea level rise, such as those with the Intergovernmental Panel on Climate Change (IPCC) and its followers with NOAA and NASA.

In other words, linear projections of sea level rise are likely to be widely off the mark by the end of the 21st Century as the net flow from cryosphere to ocean is looking to be nonlinearly accelerating.

Net mass flow is moving from mainly cryosphere (Greenland and Antarctica) to the ocean, with the resultant sea level rise from each region affecting global sea level is amazingly different ways, but a consistent story beginning to take shape that tells us to expect this shift in mass from cryosphere to ocean to accelerate as the 21st Century progresses.

Revised tallies confirm that the rate of sea level rise is accelerating as Earth warms and ice sheets thaw

The loud divergence between sea - level reality and climate change theory — the climate models predict an accelerated sea - level rise driven by the anthropogenic CO2 emission — has been also evidenced in other works such as Boretti (2012a, b), Boretti and Watson (2012), Douglas (1992), Douglas and Peltier (2002), Fasullo et al. (2016), Jevrejeva et al. (2006), Holgate (2007), Houston and Dean (2011), Mörner 2010a, b, 2016), Mörner and Parker (2013), Scafetta (2014), Wenzel and Schröter (2010) and Wunsch et al.

That's a key reason surface temperatures haven't appeared to warm as fast as many had expected in the past ten years — although ocean warming has sped up, and sea level rise has accelerated more than we thought, and Arctic sea ice has melted much faster than the models expected, as have the great ice sheets in Greenland and Antarctica
