Hansen Convicts Himself Of Data Tampering

In 1998, Hansen wrote :

it is clear that 1998 did not match the record warmth of 1934, which occurred during the Dust Bowl era

NASA GISS: Global Temperature Trends (This document was deleted from NASA servers in 2004 or 2005)

His 1998 graph showed 1998 as being the third warmest year – after 1934 and 1921, with 1998 a full degree cooler than 1934. It also showed a strong cooling trend after the 1930s.

Two years later he simply altered the data to make 1998 warmer than 1934 and 1921.

The animation below shows how he magically altered the data to match the theory.

  1. I will say it again: This should be front-page news, around the world. (Well, to be fair to myself, and again: So should my Venus/Earth temperatures comparison–it should have been front-page news soon after I did it, nearly 3 years ago.)

    • Roy Spencer says:

      actually, Harry, Venus absorbs less sunlight than the Earth, despite being closer to the sun, because it’s albedo is so high from perpetual thick clouds.

    You can tell who the real deniers are, by presenting them with this animation. Every sane person who views it understands the lunacy, only the deluded make excuses for the adjustments.

  3. Eliza says:

    This has been shown many times here and should continue to be shown

    Outside of the government’s FantasyLand home base, Hansen would have been prosecuted for fraud a long time ago.

    And on the back of this politically motivated fraud foisted on to the whole western world, we have ensured the uptake of expensive radical changes to our way of doing business, we now live with fuel and energy costs skyrocketing, and futures that will continue to be blighted by this deceitful treachery.

    Mr. Obama remove this wall of fiction from our lives. End the indoctrination of UN Agenda 21 on our children and our society.

    Here’s another NASA/Hansen 1999 quote: “in the U.S. the warmest decade was the 1930s and the warmest year was 1934.” (or here)

    There’s also an interesting discussion here:

    Note that NASA says that the revisions to the data were done by NOAA’s NCDC, not by NASA/Hansen.

    I made some inquiries a couple of years ago, to try to learn the rationale for those revisions. Here’s an email transcript:
    Note that, due to top-posting, it’s mostly reverse-chronological. The original inquiry is the heavily indented green text about 50 lines up from the bottom.

  7. Phil Jones says:

    Most would claim the above represents only US temperature… And when Global Temperature is added in we have 1998 as the hottest year while the chart Globally changes to show a consistent upward trend…

    How would folks on here respond to that??
