Very revealing programmer comments found in the hacked emails in the Climategate scandal, and they explain how we have 'Global Warming' no matter what the temperatures may actually be.
And note how they call the temperatures they want to see the 'real' temperatures, when ordinary people might think the MEASURED proxy temperatures would be the 'real' temperatures or else the proxy temps are worthless anyway!
Climategate: hide the decline ? codified | Watts Up With That?
WUWT blogging ally Ecotretas writes in to say that he has made a compendium of programming code segments that show comments by the programmer that suggest places where data may be corrected, modified, adjusted, or busted. Some the HARRY_READ_ME comments are quite revealing. For those that don’t understand computer programming, don’t fret, the comments by the programmer tell the story quite well even if the code itself makes no sense to you....
