Understanding Climategate's Hidden Decline

So not only did conspirators cherry-pick the one series of the four that approximated measured temperatures the longest, they also terminated that series at the point that it too, began to trend down. They then joined it to the actual 1980-1999 temperatures to “hide the decline” in the final product, as that decline created an inexplicable divergence between the reconstructed and measured temperatures..the existence of which challenges the entire series dating back to 1000 AD.

Remember, all the temperatures prior to 1850 were estimated by computer algorithms, and no actual readings exist to prove or disprove those figures. So a relatively short window of opportunity exists to test the programs against observations. Had 20th-century measured temperatures continued to align with those recreated as smoothly after 1960 as they did previously, then the programmers could declare their code and hence their millennial temperatures sound. But the divergence, if allowed to stand, instead reveals serious design flaws in the proxy reconstructions...which suggests that just as the decline was dealt with through trickery, so was the MWP.

Read the whole thing.  There's a lot more.
