The figure is labeled in the NOAA report with the following comment: 


“Figure 3. a) GMSL rise from -500 to 1900 CE from Kopp et al. (2016a)’s geological and tide gauge-based reconstruction [black line with blue error estimates], from 1900 to 2010 from Hay et al. (2015)’s tide gauge-based reconstruction [black], and from 1992 to 2015 from the satellite-based reconstruction updated from Nerem et al. (2010) [magenta]…”



Dr. Morner believes this curve has almost no backing up by observational facts in nature itself.



Again like flaws of the Gore-Mann hockey stick chart this new NOAA  sea level hockey stick chart has foundational errors:


a.       The foremost error is the implication that the world’s sea levels operated within a relatively narrow range for the past 2,500 years until the late 20th century when mankind began to produce large amounts of industrial CO2. At which point during the satellite era, shown in magenta color on the far right of the chart, the world’s oceans took off on a high rate of sea level growth that NOAA’s says will swamp mankind’s largest coastal cities by 2100. Mann’s hockey stick chart had the identical false premise. Al Gore may not get his previously predicted 21 feet of sea level rise but NOAA’s 8 feet can still do a lot of damage, providing him some vindication, right? Wrong!



b.      This chart, which grafts on recent satellite measurements onto the extensive tidal gauge measurements covering hundreds of years, is a patently false picture of global sea level trends. It improperly combines two disparate data sets using vastly different measurement methods with substantially different sea level rise rates in an attempt to portray an accurate and coherent sea level rise trend. This latest ‘hockey stick’chart put together by NOAA is yet another wholesale and historical embarrassment to the scientific community. It is without question, unrepresentative of what sea level rise has been and in no way should be relied upon for future sea level height projections. 



Work done by me and others using highly reliable solar driven climate models along with Dr. Morner’s historical measurements over the eons of sea level rise and fall, suggest a more accurate picture of the next seven or eight decades of sea level rise. He and I announced as much during an August 2014 news conference in Miami:
