Satellite sea level data has been “adjusted” upward by 34% over past 9 years alone

THE HOCKEY SCHTICK |October 30, 2013

There are many documented examples of sea level data from satellite altimeters being “adjusted” upward many years after publication, often repeatedly on the same data, and in defiance of the laws of probability, always in an upward direction. Seven documented examples can be found in the links in this post. A recent comment in a sea level article on the Yale Environment 360 site documents another example of sea level data being adjusted upward by 34% [by 1 mm/yr, equivalent to an additional 4 inches per century] over the 9 years since it was collected and published on the University of Colorado website.

Data published on U of Colorado website in 2004 shown in blue. Same data after 9 years of adjustments published on same website today shown in red. The slope of the same 1992-2004 data has somehow increased by 34% over the past 9 years. 

H/T: Based upon the comment by Steve Case in this article:

Here’s an interesting presentation by Dr. R. Steve Nerem, who is well quoted in the article:

“Why has an acceleration of sea level rise not been observed during the altimeter era?” R. Steven Nerem (University of Colorado)

One has to wonder what all the excitement is about if for the last twenty years there has been no acceleration of the rate. Couple that with the fact that it’s rather easy to determine that there’s been a good deal of inflating the rate of sea level rise by those same CU Sea Level Research Group scientists.

Simply put the URL of their home page (http://sealevel.colorado.edu/) into the Internet WayBack Machine (https://archive.org/) and see for yourself.

Changes have been made to the data resulting in an increase in the rate of reported sea level rise by nearly a millimeter per year.

Also see my comments on the same article:

Sea levels have been rising naturally for the past 20,000 years and at much, much faster rates in the past (up to 40 times faster than today). http://www.globalwarmingart.com/wiki/File:Post-Glacial_Sea_Level_png

Sea levels are currently rising 4 to 8 inches per century, and there is no acceleration, which means there is no evidence of a human influence on sea levels: http://hockeyschtick.blogspot.com/2013/09/new-paper-finds-sea-levels-rising-at.html

References finding no acceleration:

JM Gregory et al Journal of Climate 2012, M Beenstock et al 2013, NOAA 2005-2012 Sea Level Budget, Dean & Houston 2011 & 2013, Scafetta 2013, Holgate 2007, Boretti 2012, Morner 2004, Jevrejeva et al., 2006 & 2008, Wöppelmann et al., 2009

“no long-term acceleration of sea level has been identified using 20th-century data alone.”

“It is likely that GMSL (Global Mean Sea Level) rose between 1920 and 1950 at a rate comparable to that observed between 1993 and 2010”

… the authors find that sea level rise is a localized rather than global phenomenon, with 61 percent of tide gauge records demonstrating no change in sea levels, 4 percent showing a decrease, and a minority of 35 percent showing a rise. This implies relative sea level change is primarily related to subsidence or post-glacial rebound (land height changes) rather than melting ice or steric sea level changes (thermal expansion from warming). http://hockeyschtick.blogspot.com/2013/09/new-paper-finds-sea-levels-rising-at.html

  1. If a graph (data) is adjusted it means the data is adjusted. So the data is not considered accurate – it is estimated data. How do you measure the ocean;s height in real time anyway. With tides,, neap tides, wind, storms, currents.etc,etc Do you that an average – when, how often, where. Fossils in seaside cliffs show that the sea was far higher millions of years ago – or does it – maybe the land mass is rebounded from the last ice age, or plate tectonics are pushing the land upward or …… The best scientists are out of their league – too many variables and no real data to work with.
