UPDATE 12/4: The computer models for climate have been wired to produce hockey sticks. If you ever wanted a smoking gun, this is it. This chart shows one built-in algorithm which adjusts the temperature data to produce hockey sticks. You can see how dramatic the adjustments are - they will show hockey sticks even if random temperature data is input.
As investigators pour through the CRU data, they are finding ever more examples of fraud. The climate models themselves are coded to show warming: a bias to suppress the past and elevate the future is wired in. Previously investigators had shown that even random data plugged into the models showed hockey sticks. As I put it, garbage in, gospel out. Now they have reviewed the code itself and found the biased routines:
There are more code examples of built-in warming. The comments in the code reveal the fraud, with statements like "stop in 1940 to avoid the decline."
In 2 other programs, briffa_Sep98_d.pro and briffa_Sep98_e.pro, the “correction” is bolder by far. The programmer (Keith Briffa?) entitled the “adjustment” routine “Apply a VERY ARTIFICAL correction for decline!!” And he/she wasn’t kidding. Now, IDL is not a native language of mine, but its syntax is similar enough to others I’m familiar with, so please bear with me while I get a tad techie on you.
Here’s the “fudge factor” (notice the brash SOB actually called it that in his REM statement):
valadj=[0.,0.,0.,0.,0.,-0.1,-0.25,-0.3,0.,-0.1,0.3,0.8,1.2,1.7,2.5,2.6,2.6,2.6,2.6,2.6]*0.75 ; fudge factor
These 2 lines of code establish a 20 element array (yrloc) comprised of the year 1400 (base year but not sure why needed here) and 19 years between 1904 and 1994 in half-decade increments. Then the corresponding “fudge factor” (from the valadj matrix) is applied to each interval. As you can see, not only are temperatures biased to the upside later in the century (though certainly prior to 1960) but a few mid-century intervals are being biased slightly lower. That, coupled with the post-1930 restatement we encountered earlier, would imply that in addition to an embarrassing false decline experienced with their MXD after 1960 (or earlier), CRU’s “divergence problem” also includes a minor false incline after 1930.
