Cheating With Sea Level – Same Old Data Tampering Story

In 1982, NASA showed about three inches (~8cm) of sea level rise from 1880 to 1980.

The EPA now shows double that amount, six inches of sea level rise from 1880 to 1980

This image overlays the two graphs, to show how they have doubled sea level rise as funding and political requirements have changed.


Particularly interesting is how in the 1982 study, sea level went flat after 1950. The EPA has conveniently made that disappear.

    Neither graph makes accommodations for aquifer depletion. Each graph should show what the the effect is for aquifer depletion, ice melting, corrections and ocean expansion to inform the public better of what each contributes to the overall rise in sea level. If they did, aquifer depletion would overwhelm the other effects and make the climate alarmists look foolish.

    • Lonny Eachus says:

      Land subsidence is, on average, compensated by the lifting of land elsewhere. So subsidence only accounts for regional measurements of “rise”, and tends to be averaged out by regional measurements of “fall” in other places.

      Still, let’s not forget that those prone to cherry-pick have pointed out the areas of land subsidence as “sea level rise”, and ignored the areas where land has been rising, which by the same measure would be lower sea level.

    If you use the Internet Archives WayBack Machine you can find old pages from CU’s Sea Level Research Group:
    and old versions of raw data files:

    Download (copy and paste) into Excel and use Excel’s Slope function to figure the rate of sea level rise for the entire time series:

    year msl_ib_ns(mm) #version_2004_rel1.2
    1992.928 -4.489

    2003.842 18.55

    You will find it comes to 2.6 mm/yr

    Do the same thing for today’s version except find the slope for the same time series as the above (#version_2004_rel1.2)

    year msl_ib_ns(mm) #version_2015_rel2
    1992.9595 -5.818

    2003.873 30.516

    You will find the rate to be 3.5 mm/yr

    Over the last ten years the historical data for satellite sea level has been rewritten resulting in an increase of 0.9 mm/yr in the rate of sea level rise.

    It’s funny how the alarminati don’t like satellite derived temperatures but when they found that satellite based sea level measurements sang their song they couldn’t help themselves.
