Sea level fraud by the Colorado Sea Level Research Group

A quick holiday fund-raising campaign for Behind the Black!
Scroll down to read this post.
In past years I have managed to avoid asking for donations for Behind the Black during the holiday season. My finances however now compel me to do a short one-week fund-raiser, from November 11 to November 17.
I do not use Twitter for ethical reasons, which I have been told cuts down on traffic to the website. So be it. Furthermore, Facebook has clearly acted in the past two years to limit traffic to Behind the Black, almost certainly for political reasons. So be this as well. Finally, I do not post outside ads, as I have found them annoying to my readers and not that profitable to me.


Therefore, I need to ask for the direct support from my readers. If you like what I do here, please consider contributing, either by making a one-time donation or a monthly subscription, as indicated in the tip jar below.


Regular readers can support Behind The Black with a contribution via paypal:

Or with a subscription with regular donations from your Paypal or credit card account:

If Paypal doesn't work for you, you can support Behind The Black directly by sending your donation by check, payable to Robert Zimmerman, to
Behind The Black

Or you could consider purchasing one of my books, as indicated in the boxes scattered throughout the website. My histories of space exploration are award-winning and are aimed for the general public. All are page-turners, and all not only tell the story of the beginning of the human exploration of space, they also help explain why we are where we are today. And I also have a science fiction book available, Pioneer, which tells its own exciting story while trying to predict what life in space will be like two hundred years in the future.


Note that for this week only I am also having a sale on the purchase of the last 20 hardbacks of Leaving Earth. (Click on the link for more information about the book, which was endorsed by Arthur C. Clarke himself!) This award-winning out-of-print book is now only available as an ebook, but I still have a handful of hardbacks available, normally for sale for $70 plus $5 shipping. For this week only you can buy them, personally autographed by me, for $50 plus $5 shipping! Just send me a check, payable to Robert Zimmerman, to the address above, with a note saying that the money is for the Leaving Earth hardback.


Please consider donating. Your help will make it possible for me to continue to be an independent reporter in the field of space, science, technology, and culture.

The dishonesty of climate scientists: A comparison of the raw data with the published adjusted sea level data reveals unexplained “adjustments” made by the Colorado Sea Level Research Group at the University of Colorado that increase the reported rate of sea level rise without any explanation.

In 2004, the rate of sea level rise for the 1990s was measured at 2.8 mm per year (margin of error 0.4 mm). Somehow, in 2015 that same data for the 1990s now shows the rate to be 3.3 mm per year, adjusted upward 0.5 mm per year, an amount greater than the margin of error noted in 2004. There is no justifiable reason that I can see for these adjustments, and if there is, they have not provided it.

Be sure you click on the link and look at the graphs. They are quite damning.

Note also that when I began my effort to unravel the climate change field back in 2004, I spent a lot of time reading older literature describing then what was known about sea level rise. These earlier published papers from the late 1990s, generally agreed that the rate of sea level rise for the past century had averaged around 2 mm per year. When I started looking at the modern data in 2004, however, the accepted rate was 2.8 mm, but I could find no explanation for why the consensus had upped the number from 2 mm. Nor did any published work explain how the previously published sea level data from before 1990 had somehow changed to this higher number.

They have now upped the rate again to 3.3 mm per year, but have once again provided no explanation as to why. The adjustments themselves are very suspicious, since they all go in one direction. Either they are allowing their biases to color their judgment, or they are committing outright fraud for the sake of selling the idea of global warming.

Either way, this is not science. Until they provide a good explanation for the adjustments, their funding should be stopped, now.

One more thought: Even at higher 3.3 mm per year, the total sea level rise for the next century will be a whopping one foot, hardly something to panic about.

    This is what you get when you measure sea level from a mile high and two thousand miles from the sea, maybe they should think about moving a little closer?

    (high IQ sarcasm alert)

    I would be more worried about the sea levels dropping.

    They would only drop for two reasons. Both very bad.

    One the glaciers are rebuilding and we are starting that ice age we are due for. Buy a new winter coat and expect less rainfall.

    Our oceans are being stolen by aliens at a rate noticeable by man. All hail our new overlords.

    We have all heard of “social justice”, now we have “climate justice”.

  • Edward

    It is reasonable for us to consider the possibility that a fraud is being perpetrated upon us.

    1) Explaining data and the differences between the data taken and the data used is basic science; more basic than Science 101, it is middle school science. It is the first thing taught about data reporting in the first science class in which a student is required to collect data. Thus for the Colorado Sea Level Research Group at the University of Colorado to ignore the data discrepancy is a violation of basic science.

    2) They should have noticed the discrepancy in the data between their own reports. It is their business, after all. Both graphs list TOPEX satellite data as their source for the 1993 to 2002 portions of the plots, but it is obvious by inspection that the data points are different between the two reports. First, the 60-day smoothed lines are greatly different. Second, differences between the data points on the two graphs are clearly different near the 1998 mark and the 2001 mark, where high level readings are not as high or are fewer in number. Even the Jason-1 data can be seen as different near the 2003 mark, demonstrating that the Jason-1 datasets are also suspect. One or more of each satellite’s dataset is not the original data.

    The 2015 report should explain or reference an explanation as to why these datasets are different from their prior report(s). If this is not done, they are either poor scientists or could be suspect of intentionally hiding something. This does not seem to be on their FAQ list: or their links page: or even the AVISO page (the TOPEX data-source site) It looks like it is AVISO that has made the adjustments without explanation, but the University of Colorado does not seem to have noticed or does not seem to care.

    3) The University of Colorado changed their data-presentation method between the two years, using different colors. This is suspicious. Not only does it make noticing the discrepancy harder, it obfuscates everything about the data. To make matters worse, the more recent map has a narrower range (-10 to +10mm) than the 2014 map (-15 to +15mm), and the 2014 map shows a few locations that exceed +12mm, which is well beyond the range in the reportedly worse situation of the 2015 map.

    4) It is obvious that the satellite datasets are being tampered with, and it is further obvious that the University of Colorado is drawing conclusions based upon their altered datasets without discussing these alterations and how they might affect the accuracy of their conclusions. The faking of data (changing without notice or explanation) is the very definition of fudged data: “ To fake or falsify: fudge casualty figures”

    5) If we cannot trust the satellite data, then what can we trust in the science of climatology? It seems that it is not only NOAA but foreign science organizations are also modifying their data without announcement or explanation – two violations of established methods of science. Put together, these appear to be actions of fudging data, and it appears that the University of Colorado is comfortable using such apparently fudged data.

  • Edward,

    Your research and writing in this post is so good it should be a post on the main page. If I wasn’t in Mexico on a semi-vacation I think I’d want to put it there, with your permission. If you say yes, I will see if I can make it happen.

  • Edward

    Thank you for the compliment. You have my permission.

  • Time is my problem right now. Between sightseeing and writing about what I see, I might not be able to do it. I will try however, if I can get the time.
